Frequently Asked Questions (FAQ) for LED Down Light

Led lights strips install?

LED is designed to focus its light and can be directed to a specific location without the use of an external reflector, achieving a higher application efficiency than conventional lighting. Well designed LED illumination systems are able to deliver light more efficiently to the desired location. Also, you can have your measurements known to the seller and they will be more than glad to do the slashing for you prior to sending the items. It comes in different brightness and it is actually defined by the number and size of LED present in the strips

Controlling a normal florescent bulb using usb duplicate

Since this involves switching mains voltage, and Mains Voltage can kill, a beginner should not try to make one from scratch. Either go with a ready made commercial Usb Controlled Outlet, use a X-10 outlet designed for inductive loads with a X-10 Usb controller, or use a wireless remote controlled system that's used for outdoor lights (like they sell at christmas), with a USB GPIO module hacked to the remote control.Alternatively, use a Led light bulb, not a CFL/Florescent light. Much easier. Some can even be controlled by iphones/android

Above cabinet LED light placement

This is a matter of personal preference, however that being said you should avoid direct line of sight with the strip. For example, if you can see the LED strip while walking down stairs then it would be better to adjust the strip as to avoid this if possible as they are pretty intense on the eyes. An easy to make wooden lighting rail that basically looks like a triangle would direct the light up on the wall which has a nice effect and also keeps the light away from the eyes.

Led light strip flashing duplicate

it's not a connection issue, those don't get better over time. your driver is failing because the capacitors in it are drying out. this will get worse sooner than later. As the LED strip warms, it uses more current. To supply more current, the driver increases its output voltage. When the voltage increases, a cap of a given capacity stores more energy. When the voltage catches up with demand, the flickering stops. Note that higher voltages tend to heat the capacitors and cause them to age even faster; a run-away cycle you're in the early stages of

Arduino's Serial Monitor Showing Constant Value

In your initialisation where you declare each variable and 'connecting' them to a pin you make a mistake. Now you say that senRead is a digital pin instead of a analog pin. Change the value to A0 so you will get int senRead A0;Also in your void Setup() you forget to declare your analog pin as an input. Add a pinMode command that sets senRead as an input. If this doesn't fix your problem then it is probably hardware related. Check the connections on your breadboard will most of the times solve alot of problems.

how can money save a polar bear?

You should be suspicious when someone asks you for money to save polar bears. You could donate money to a reputable organization, like the World Wildlife Fund. If you want to save polar bears by stopping global warming, use alternatives for fossil fuels or use energy more efficiently. Use compact fluorescent lights or LED lights instead of carbon filament lights. Walk, cycle or take public transit, where possible, instead of driving. Install solar panels on your house. Write a letter to your regulatory agency and your power supplier in support of nuclear power.

What's the difference between a Plasma-TV, LCD-TV and a LED-TV?

Plasma TVs are emissive devices. A gas is excited to radiate either red, green or blue at each screen pixel. LCDs (Liquid crystal displays) are transmissive devices. Each pixel is a variable transmission shutter whose transmission is varied by varying the electric field on it. A cold cathode fluorescent lamp is used as the backlight. LED (light emitting diode) TVs are identical to LCD TVs but use LEDs as the backlight. They typically use less power and allow greater control of the backlight intensity in different parts of the screen. They also allow a much thinner screen.

How do those new flat LED street lights save energy ?

LED offer excellent visibility with color accuracy, they lose nothing when it comes to energy efficiency, In fact, they significantly outperform HPS lamps in this category. When comparing the two, energy-saving lights bulbs consume 40-80% less electricity than do standard HPS lamps. A 30W LED lamp approximates the light output of a 80W HPS. This feat of efficiency stems from the directionality of LEDs, which focus light downwards and spreads illumination evenly over a given area. As a result, one LED lamp requires significantly less wattage than does an HPS to illuminate the same area

------

Does this RGB LED really need 220 ohm resistors per color?

In my experience, red will dominate when using the same resistor values with the same voltage applied to each pin (common cathode). This is because the RGB LEDs I have used (and the one you are using) have a 2V drop for red, and 3.2V drop for green and blue. PWM can compensate for that (as can a higher resistance value on the red pin), depending on how you program the duty cycle for each pin. They are probably telling you to use the same resistor value to make the project simpler and cheaper

Bedtime for 12-13 year old girl

Let her go to bed a half hour later for a week and see how she acts. If she is harder to wake up in the morning, forgetful, cranky, etc, move it back to the usual time. If, however, everything remains the same, keep it going for a month and then make bedtime 10pm. Do this again, for a week and see how it goes. A week of too little sleep won't hurt her, and if she really doesn't need the sleep, lying in bed wide awake like that can cause insomnia later on

Is this a good laptop?

my advice would be try and avoid lithium ion batteries as mine in my laptop have already burnt out after a month because its constatly plugged in and its got power managent software which is meant to incease battery life not decrrease it i know they last longer but ateast with the old ones they will last longer and wont burn out ive got a old hp laptop aswell thats about 8 years old and the battery in that still lasts for 5 hours and thats constantly on charge whats wrong with the good old fashioned batteries ay?

How to turn off a light sensor LED light?

The white "screws", are knockout plugs. A knockout is simply a hole where conduit, cable, wire, or a device can attach/enter the box. A knockout plug, is used to fill unused knockouts.Here is a similar box cover with the knockouts unplugged.

This allows you to attach devices, like lamp holders and motion sensors.Any extra holes would be filled with a plug.You should be able to hire an Electrician to install a switch as you mention, but it would depend on if you have the legal right to (own vs. rent, etc.

Why is everyone that is looking for LED lamps, also looking for China LED light manufacturers?

Why is everyone that is looking for LED lamps, also looking for China LED light manufacturers?They aren't.As somebody who uses A LOT of lighting equipment of every configuration, I recommend people source standard configuration LED lamps from the major manufacturers, such as Philips or GE, or perhaps Cree or TCP, or even Feit. If it's specialized configurations, find a manufacturer who will stand behind the product (ie: take it back if it blows out and replace/refund as appropriate).

Efficiency of solar panel under warm-white LED light

You may find some other LED (cool white, or blue or even red) has a higher overall efficiency. And you probably need to arrange multiple LEDs for maximum evenness of illumination to avoid energy loss in the "shaded" part of the solar cell, and possibly reflectors to minimise spill outside the cell area.But once you factor in the LED's own efficiency, even the best cheap solar cells (currently about 22%, back contact cells like Sunpower Maxeon) won't give you 5%. Jonk's 1% may be realistic, but with care and experimentation you may be able to reach 2% or so

Magnetic connector for LED light on tent mesh

I dont know of anything off the shelf that is a magnetic connector but there is a thing called a cable pass-through or cable gland that you could use to pierce the netting and pass your cable through while sealing it from insects. Go to an electricians shop and describe what youre up to. Alternatively if you dont mind ugly, you could hand stitch or glue a patch of camp mattress foam into the netting with a slit in it that would allow you to push your wire through while keeping out the bugs.

Where can I find a linear mount LED light?

the present passing contained in the direction of the wires will reason the wires to warmth up if no longer adequate guage. think of of the thousands and thousands of little electrons pushing and shoving lower back and forth, all this action reasons friction on a molecular point and of direction all of us know friction equals warmth. In a larger guage twine there is extra area for the same style of electons. that is incredibly that easy. Use as heavy a guage speaker twine which you will. you will have no sign loss and little warmth

King James Bible archaic style

The answer to your first question probably lies in the fact that the Old Testament is translated from Hebrew. Arabic frequently begins sentences with and. I wouldnt be surprised if the other main Semitic language did the same.

We might need a biblical scholar to answer your second question. It is, Id hazard, to do with the respect due to the Almighty, just as some people begin pronouns referring to God with a capital letter.(If you're interested in other linguistic aspects of the King James Bible, I recommend David Crystal's 'Begat'.

What is the main advantage of LED light bulb ?

The future of household lighting will soon be the wide spread adoption and use of white energy efficient LED light bulbs. Though the present market for finished white LED products is geared mainly towards enthusiasts and early-adopters, the efficiency and cost effectiveness of LED lighting systems will drive demand for more affordable LED lights. Opto-electronics is an exciting area and we predict, that in the near future, white LED lighting applications will be powerful and cheap enough to replace incandescent lighting for everyday use in our homes, in street lights, outdoor signs, and offices.

Best led or LCD tv for watching tv and gaming?

plasma is better due to it does NOT have motion blur that you get with SOME lcd tv's LED TV is a bit of a misnomer but as manufacturers and retailers continue to use the term, it makes it's way into the public conscience and is worth deliberating on the differences. LED televisions are really just LCD televisions that use LED lights for back lighting instead of the flourescent CFL lighting traditionally used for LCDs. Both employ the liquid crystal diode (LCD) technology front panel containing the twisting crystals which define LCD technology.

How Does Traditional Market Research Integrate Blockchain
Insights network launched the install blockchain, which is one of the most unique blockchain technology use cases seen in the world. In this article, we will discuss how our blockchain Market Research Network works from a technical perspective, and how this technology can improve data quality, reduce costs, reduce fraud, and empower data creators.Next, we will focus on some of the most common problems in the traditional market research industry. Since the birth of the Internet, there has been no innovative standard practice in the traditional market research industry.Problem: low quality users. Unconfirmed false data. The traditional panel only allows users to register and select demographic information. We call it personal data value (age, gender, income level, number of children, pet owner, etc.). IP address detection is the basis for deciding whether to allow consumers to participate in the survey. In some cases, a method called "river sampling" is used to conduct real-time surveys of respondents. In this method, anyone who visits the survey link will begin to be screened for demographic questions and enter the relevant surveys (if available). This will lead to a poor user experience, which we will discuss in another article on this blog.Solution: verify the blockchain account. The submitted value is assigned to the install blockchain account as a hash value after verification. The insights network blockchain authentication account is assigned a hash value, allowing the account to participate in the smart contract. The identity is verified by a third-party authentication partner, and the value of the profile is submitted as an unexplained hash value, so it is impossible to know what value is assigned to each user. We use our patent application zero knowledge proof authentication scheme as a filter to ensure that authentication partners cannot track the documents they are validating. The technology we are applying for patent will be published and disclosed in detail before the end of 2019. Next, you will see the account verification record that occurs in real time and recorded on the blockchain. In this example, the account "fbtiezh3sty4" has received the authentication credentials assigned to its account and submitted to the install blockchain as "commit".Install blockchain record of the validated profile value submitted to the blockchain accountProblem: poor user experience. When conducting the survey on the traditional market research platform, a method called "river sampling" is adopted to conduct real-time survey on the respondents. In this method, anyone who visits the link will begin to be screened for demographic questions and guided to the relevant survey (if any). This leads to a bad user experience, and users constantly jump out of the survey in the process of accepting the survey. This is a waste of investigators' time and creates great frustration among the team members, resulting in a low retention rate of the team. For example, a requester can set a condition that only men aged 30-40 who drive a white car, own a dog and have mortgage debt are eligible to participate in the survey. Instead of predetermining these values before service users, they ask them when investigators conduct surveys. Some surveys may take 45 minutes to complete. Imagine that you spent 25 minutes completing a survey, but when they asked you if you had a pet and you said no, you were rejected. What would you think. This happened to most respondents.Solution: determine the "match" in advance before providing users with investigation opportunities. Through the smart contract on the install blockchain, you can find the value of the blockchain account submitted to each user and the local storage of the encryption profile value on the user's device. Every time a survey opportunity is created and funded, it enters the insights network data exchange smart contract. The contract then polls each device connected to the network for a device that matches the requested survey. The same selection criteria as traditional market research products can be set by the requester, but it does not allow anyone on the local IP address to access the survey - just to pop up unqualified participants afterwards - the smart contract searches for active devices on the network and only shows the survey opportunities to providers who meet the exact criteria specified by the requester. We use the so-called disconnection circuit to calculate the encryption profile value of each user to determine the "match". During the matching process, encrypted data polled for eligible demographic data will never be decrypted - giving users complete control over the visibility of their data. Here is how to record a match on the blockchain:Complete the "matched" install blockchain recordOnce a match is determined, the provider can see an investigation opportunity. Users can view the compensation provided for completing the survey, the personal data requested and the submitted data, and agree when exchanging personal data and responding to the survey. The submitted answer cannot be represented by a hash value.Install blockchain record for data exchangeQuestion: can you really believe these data? Most panel companies that complete the brand survey sample provide data sets to brands in an opaque situation. Previously, the industry has been plagued by the sharing of personally identifiable information (also known as "PII"). However, with the introduction of the general data protection regulation (gdpr) by the European Union (EU), this system has undergone major adjustments. It is illegal to collect consumers' personal identity information and sell it to a third party without consumers' consent. If the PII of consumers cannot be shared, it is more difficult to provide accurate information about the surveyed users. Nevertheless, most online panel companies have completely unauthenticated user databases, and trust in people is the only determinant of data quality.Solution: the blockchain can verify the transaction ID. When running an example on the insights network, the blockchain transaction ID is associated with each respondent. This creates audit trails that are not available in the current market research industry. There is now a clear record of team members' submissions and the relevant summary values of each team member. In addition to transparency, these transaction IDS can also be used as your consent records, that is, the consumers you investigate and exchange data agree to the data exchange you pay for them. Some gdpr laws require applicants to keep records of subjects' consent. Using the insights network, this feature is built-in to the end-to-end experience.The following is a screenshot of the data export of a survey recently launched by insight networ. As the requester, this is the data you paid and the data you received. As an additional feature, insights network uses one-time pad encryption for all data you purchase. This means that insights network cannot pry into the data set you pay as a requester. After you export the data, this is the only time you can export the data.Results of a survey sponsored by insights network on the popular cryptocurrency chainlinkProblem: slow invoicing and long revenue turnover time. At present, the invoicing time of the market research industry needs at least 60-90 days, and a brand can pay the expenses of researchers. This means that team members also have to wait for their bonus. The core reason is the lack of high-quality data and deceptive survey responses that need to be evaluated and filtered from the final data set. This may take several weeks for the brand to comb through the data and determine which data sets are available and which are false. This is a particularly painful experience for group companies because they are waiting for feedback from the brand. Basically, the brand tells them how much they will get from the data set provided by group members.Solution: early data verification and smart contract payment data exchange. As mentioned in this article, the verification of profile values, matching on blockchain and smart contract governance create a more efficient and high-quality end-to-end experience. The last thing to record is the payment scheme. Because surveys can be provided to pre-determined, pre validated audiences, payments occur immediately and are subject to smart contracts. Install cryptocurrency provides funds for the smart contract according to the budget determined by the requester, and pays the provider with blockchain transaction immediately after the provider submits and agrees to the data exchange. The following is the transaction ID of the data exchange smart contract paid to the provider who completed and agreed to exchange in the network.Blockchain transaction ID of payment data exchangeCryptocurrency payments on the blockchain and install blockchain are borderless and can be sent to anyone around the world within 1 second. It also opens up access to emerging markets that were previously inaccessible due to the collapse of their banking systems.Development prospectAt present, we are running the survey sample on the install blockchain network as the first use case of insights network. This technology has unlimited scalability, can safely verify data, and communicate privately on the network in a transparent record, such as sending bitcoin payment to friends. Some future use cases we are dealing with include releasing previously unavailable data exchange / sharing opportunities, such as nuclear power plant data exchange, PII involving Enterprise Market Research (Q4) using secret state data prediction, and simpler use cases, such as receipt data exchange and micro customer experience survey. The most beautiful aspect of blockchain technology is the global cooperation opportunities it provides.Source: blocknet
