LED as a lighting source currently needs to be solved

LED as a lighting source is still a problem that needs to be solved at present. In fact, the current LED is still facing some problems in the field of lighting. The reason why it can arouse people's high attention is mainly because its characteristics in terms of energy saving, environmental protection, longevity, safe low-voltage ignition and variety of shapes are unmatched by traditional lamps, but currently on the market led lighting products Due to factors such as the materials used, manufacturing industry, and cost, these characteristics cannot be fully demonstrated. These products are side by side and mixed. According to the use environment, there are mainly outdoor and indoor lamps. For example, outdoor lamps mainly include: street lamps, landscape lamps, construction spotlights, car lamps, wall washers, floodlights, etc.; indoor lamps mainly include PAR lamps Series, GU(.,)(MR) series, fluorescent lamp series (mainly T), candle lamp series, down lamp series, recessed lamp series, wall lamp, ceiling lamp, curtain wall, etc., track lamp, etc. According to the direction of light emission, it can be divided into directional lights and non-directional lights. Unfortunately, regardless of the appearance or purpose of these lamps, we can find the shadow of traditional lamps. In other words, in the current lighting field, LEDs have not yet positioned themselves, and they are not entirely their own. This has seriously affected the development of LED in the field of lighting.　　In terms of technology, LEDs also face some difficulties. For example, heat dissipation. According to related research and years of work summary, at present, a good light source design can make the electrical-optical conversion efficiency reach about %. But still% of electric energy is converted into heat. Take a W led bulb lamp as an example. If the driving efficiency is %, then the light source gets the power of W. According to the electric-to-optical conversion efficiency of %, there is still .W electric energy converted into heat energy, plus the front driver board For the loss of about W, a W bulb lamp will produce .W heat energy. This is the main reason why the temperature rise of the led lamps we designed remains high.
