If a 100 Watt Incandecent Bulb Is Equal to a 23 Watt Flourecent Than a 21 Watt LED Light Is Equal to

Look at the output in lumens. A 100W incandescent lamp and an equivalent fluorescent lamp give around 1750 lumens. Your LED could be anywhere (expect it to be between 840 and 1600). 60W incandescent lamps give around 825 lumens. Also look at the color of the LED if they have it. 6500K is white(ish). Anything higher than that is pretty blue

4. How to improve the white LED light efficiency? What are the solutions? - NEWS - Yangzhou Xinghui Lighting Engineering Group Co., Ltd.

a) Enhance the internal quantum efficiency to generate more blue light in the active region and reduce the absorption at the blue output. With the development of epitaxial growth technology and multi-quantum well structure, the internal quantum efficiency of ultra-high brightness LEDs has been very large. Improvement, blue LED has reached more than 90%; b) Improve the light extraction efficiency, adopt the flip-chip structure to avoid the electrode and gold wire of the formal structure to block the light; balance the contradiction between the light absorption and the diffusion current of the transparent conductive film; the bottom reflection layer causes the blue light to reflect in the front light direction; the surface pattern or surface Roughening technology avoids excessive total reflection due to large difference in refractive index; etc.; packaging material close to the refractive index of the chip; c) improving the external quantum efficiency of phosphor photoluminescence conversion, developing phosphor materials and ratios with high photoluminescence conversion efficiency; d) Improve the light-emitting efficiency of the package. The high refractive index of the package material is beneficial to the extraction rate of the chip light, but it also increases the difference in refractive index from the air. For the planar package, it causes the total in-reflection with the air interface. Increasing, thereby reducing the light extraction rate, therefore, a secondary transparent encapsulation layer with a refractive index transition can be considered on the planar package; in addition, for non-planar packaging, the phosphor coating thickness is improved and The shape and the shape of the package structure avoid excessive total reflection of the emitted light due to the large difference in refractive index. The highest light efficiency of blue chip type white LEDs is mainly limited by four parts: 1 The internal quantum efficiency of blue light is estimated to be no more than 90% (under high temperature influence, while low power normal temperature can reach about 95%); 2 The light extraction efficiency of the epitaxial layer is estimated to be no more than 85% (the total reflection angle determined by the refractive index of the material of GaN and silica or epoxy resin in the formal and vertical structures is about 42; the total reflection threshold of GaN and Al2O3 in the flip-chip structure) The angle is about 46; it is estimated that the pattern optimization will not exceed 75); 3 The highest quantum efficiency of blue light converted to white light is estimated to be no more than 70% (see the most efficient lossless single-spectrum 555nm green light, and the photoluminescence efficiency of all blue light converted to 555nm monochromatic green light is less than 78%); 4 Phosphor layer white light out of the ball type package efficiency is not more than 95% (plane package output rate will be much lower, this one is usually less concerned, because light from silica gel or epoxy resin to the total reflection of air The critical angle is only about 42). The integrated optical efficiency of the four parts multiplied is estimated to be no more than 50%; that is to say, the luminous efficacy of the blue chip type white LED does not exceed 340 Lm/W. According to reports, the world's highest luminous white LED is the US CREE company announced in March 2014 that 303Lm / W. It is close to the limit of the estimated white LED efficacy of the above analysis. Progress in Light Efficiency of White LEDs in Silicon Carbide Substrate of American CREE Laboratory China's current domestic LED light efficiency has also gradually caught up with the international advanced level. Many years ago, the Nanchang University team in China used pre-rasterization etching on silicon wafers to alleviate the cracks and dislocation defects caused by the large difference in thermal matching during the cooling process after GaN growth. The key components of MOCVD equipment were improved by special measures. The trachea" to improve the uniformity of GaN growth and other independent patented technology, broke through the key technology of high-efficiency GaN-based blue light-emitting diodes on silicon substrates, and became the third country to master the independent intellectual property rights of blue-light LEDs after Japan and the United States. It broke the situation that Japanese sapphire substrate and American silicon carbide substrate have long monopolized the core technology of international LED lighting, and formed a global three-pronged force with Japanese and American technology. According to the "2018 China Blueprint for the Development of Semiconductor Lighting Industry" released by the National Semiconductor Lighting Engineering R&D and Industry Alliance: "In 2018, China's industrialized white LED light efficiency level reached 180Lm/W,3%,6%". This is commendable, but in the semiconductor integrated circuit industry, 8 inch, 12 inch and other mainstream large-size silicon wafers should be applied to the LED lighting industry on a large scale. At present, the mainstream is still a small size sapphire substrate below 6 inches in the LED lighting industry. When the chain has formed a first-mover advantage, the process maturity and low-cost advantages of the silicon wafer itself cannot be exerted. It is expected that when the industrial chain such as packaging equipment is upgraded to a mainstream with 6-inch or more substrates, the large-volume demand for silicon-based LEDs will continue to return to its original cost less than sapphire and gallium nitride substrates. A lot of advantages, when the market prospects for silicon-based LED applications are very bright. In the early days, because of the low light efficiency of red light, especially green LEDs, the RGB type consisting of three red, green and blue LEDs is limited to display or decorative lighting applications. With the gradual improvement of green LED light efficiency, RGB type White LEDs enter practical lighting. The main advantages of RGB white LEDs are: First, there is no need for phosphors to convert light. This alone can theoretically reduce at least 20-30% of the photoluminescence energy conversion losses in blue chip-type white LEDs; secondly, Easy to adjust color temperature and color, which is very important in smart lighting applications. However, the main disadvantage of RGB white LEDs is that the efficacy of green LEDs is still not high, resulting in a total luminous efficiency that is currently much lower than that of blue chip-type white LEDs; another RGB three LEDs must be strictly matched with luminosity and chromaticity distribution. The light color distribution curve of the three LEDs of red, green and blue should be smooth and completely consistent and the projection direction is consistent, otherwise the luminosity and chromaticity unevenness in different distances and directions are serious; there are also three LEDs of red, green and blue. Three sets of power supply systems complicate the drive circuit and increase the cost. The uneven distribution of luminosity and chromaticity is an inherent defect inherent in blue chip type white LEDs and RGB type white LEDs, but to a different extent. Since the human eye does not perceive the ultraviolet light, the ultraviolet light emitted by the ultraviolet LED chip is absorbed by the red, green and blue primary color phosphors in the package coating and converted into white light, so the ultraviolet chip type white light LED has no chromaticity distribution like the conventional fluorescent lamp. The unevenness of the photometry is also much better than the blue chip type and the RGB type, which is its greatest advantage. The main disadvantage of UV chip type white LEDs is that, in general, when the spectral envelope of phosphor photoluminescence conversion is similar to the continuous spectrum of blue light white light, the ultraviolet chip type white light LED has higher luminous efficiency than the blue chip type. Low, the shorter the ultraviolet wavelength, the lower the conversion efficiency (the light conversion efficiency of the phosphor under 254 nm ultraviolet light does not exceed 50%), and the manufacturing difficulty is multiplied, so it is theoretically impossible to use the short-wave ultraviolet chip for illumination. Make white LEDs. In addition, high-efficiency phosphors for long-wave UV excitation are needed. Moreover, the author suggests that the spectrum emitted by the phosphor after conversion should be like the three primary colors of the energy-saving fluorescent lamp, such as red, green and blue, forming a discrete discontinuous spectrum, each of which is a narrow spectrum, and the green peak should be close to the highest light efficiency of 555 nm. The green light with red and blue light may easily exceed the limit light efficiency of the 340 Lm/W blue chip type white LED. Of course, even if the phosphor can do this, the current half-width of the light-emitting wavelength of the LED chip is not too wide, and the 254-nm working ultraviolet light generated by the low-pressure discharge in the conventional fluorescent lamp cannot be matched with the phosphor by its very narrow wavelength half-width. The effect may still be poor.

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
