With the development of the market, the LED street lamp light source is adopted more chips combined sources, but because the technology is not mature, using a combination of multiple chips in the LED street lamp light source also has some problems. Manufacturer of LED lights ED street lamp light is higher than high pressure sodium lamp many color, high pressure sodium lamp only around 23, color rendering index and the LED street light color rendering index above 75, think in terms of visual psychology, to achieve the same brightness, LED street light can, on average, more than 20% lower than the high-pressure sodium lamp. LED street lights maintenance costs low, compared with the traditional street light, LED street lights maintenance cost is extremely low, through the comparison, can recover all input costs less than 6 years. LED street light automatic control and energy saving device, can realize to meet the requirements of different times lighting cases, most likely to reduce the power, saves the electricity. Can realize the computer dimming, period and control, light control, temperature control, humanized functions such as automatic inspection. What are these problems? We will arrange for you the following instructions. First of all, let's look at the LED street lamp light more chips used in combination. According to the situation of LED street lamp market, the market LED the MCU power generally between 1 ~ 5 w, only a few hundred lumen flux output. In order to make the large-scale application in the field of general lighting, LED the luminous flux LED street lamp lighting must meet thousands or even tens of thousands of lumen, single chip can't achieve such a high light output. In order to meet such a high light output requirements, both at home and abroad have adopted a more LED chip ( Usually is 1 w) The combination of light source. So, at present the LED street lamp light source using a combination of many chips which problems? 1, Ed street lamp lighting production process trival, low production efficiency, low reliability. 2. The design of lamps and lanterns restricted by the number and arrangement of a single LED. It is difficult to give attention to both the appearance and performance of lamps and lanterns. 3. The secondary light distribution design of lamps and lanterns is complex, difficult to meet the requirements of different lighting design, reduces the luminous efficiency of lamps and lanterns. 4. Dozens of single chip installed in the same lamps and lanterns of LED. Each LED chip photoelectric performance parameters must be consistent, otherwise will greatly reduce the photoelectric performance and performance of lamps and lanterns. 5. In use process prone to partial failure caused by blind spots, blind spots, increase the maintenance cost. Above is about the LED street lamp light source using a combination of many chips still exists the problem, if you want to know more about relevant specification, you can focus on our website for more consulting, also can make a phone call to ask.
