[Text|High-tech LED reporter Long Zonghui] At the end of October, Energy Star held a regular annual meeting in the United States. At the annual meeting, a consensus was reached on increasing the frequency of sampling and shortening the test time and simplifying the test content. However, specific initiatives are still under discussion, including testing time to shorten the lumen maintenance rate and eliminating outdated and unreasonable requirements.
According to Dr. Wang Yang, director of the US R&D Testing Technology Development at the Energy Star Annual Meeting, ENERGY STAR believes that the number of LED lighting products currently on the market has risen sharply, and the market life of the products has been shortened to about one year. The six-month sampling time set is obviously too long, especially if the test sample has been placed on the market.
The US Environmental Protection Agency reiterated that the purpose of sampling is to promote market regulation and improve the quality of SSL products. At present, ENERGY STAR still insists on adopting a random sampling method of the market, and the CB (certification institution) that has approved the certification organizes the manufacturer to test in a qualified laboratory. In order to ensure that the sampling is representative and statistically significant, the number of samples is determined by a certain percentage of the total number of products on the market.
The current sampling standard for ENERGY STAR implementation is Lamp 1.1, which was launched on August 28, 2014. Compared with Lamp 1.0, which has been in operation for one year, the changes are not too large ( please download the PDF file for details ). ENERGY STAR During the sampling of 278 test products, LED bulbs did not pass the lumen maintenance test for 3000-6000 hours and the lumen efficacy and color rendering index (CRI) of the lamps and lamps. The problem of more than 5% is still very prominent. In fact, the results of the test are not compared with the parameters when the product was originally certified. The test is actually relaxed.
Although the industry and the US Environmental Protection Agency reached a consensus to shorten the test time and simplify the test content without affecting the validity of the test results. However, related initiatives are still under discussion, including the time to shorten the lumen maintenance test and the elimination of outdated and unreasonable requirements. The US Environmental Protection Agency believes that the revised test specification is a dynamic process, because some of the content involves the formulation of standards by relevant organizations such as IESNA, and no specific timetable has yet been given.
The outdated and unreasonable requirements mentioned above include that the color temperature angular distribution uniformity test is required to be high. When testing the large angle parameters of the directional lamp, the test equipment is limited to cause poor test repeatability; the ignition time test is no longer applicable to SSL. The characteristics of the product itself, the sampling results show a very high pass rate; the market has been occupied by the low CCF electronic starter, the CCF parameter test will lose its original meaning; for the zonal lumen density The restrictions are too large to be able to take advantage of SSL to meet the needs of users in specific applications such as local lighting.
In addition, this annual meeting also discussed new developments in ENERGY STAR in terms of specifications and definitions. For example, regarding the requirements of optical components in the definition of LED engines, many opinions suggest that the current definition does not meet the emerging product design requirements. The EPA will discuss with relevant parties and make appropriate amendments. In the face of the general improvement in lumen conversion efficiency, the new standards to be introduced will also need to keep pace with the industry. The hot lighting smart networking function may also be included in the "Lamp 2.0" requirements.

Road Traffic Signs are graphical symbols that display traffic regulations and road information. They can make traffic regulations visually, concisely and concisely expressed. At the same time, they also express the content that is difficult to describe in words. They are used to manage traffic and indicate the direction of driving to ensure the smooth flow of roads and the safety of driving. Applicable to highways, urban roads and all special highways, with the nature of the law, vehicles, pedestrians must comply with.
