What are the problems with the use of multiple combined light sources for LED street lights?
With the development of the market, LED street light sources began to use multi-chip combined light sources, but due to the immature technology, there are still some problems in using multi-chip combined light sources in LED street lights. LED street lamp manufacturers ED street lamps have much higher light color rendering than high-pressure sodium lamps. The color rendering index of high-pressure sodium lamps is only about 23, while the color rendering index of LED street lamps is more than 75. From the perspective of visual psychology, it can reach the same brightness and the illuminance of LED street lamps is average. It can be reduced by more than 20% compared with high-pressure sodium lamps. Low maintenance cost of LED street lights: Compared with traditional street lights, the maintenance cost of LED street lights is extremely low. After comparison, all input costs can be recovered in less than 6 years. The LED street lamp has an automatic control energy-saving device, which can achieve the greatest possible reduction in power and energy saving under the condition of meeting the lighting requirements of different periods. It can realize computer dimming, time period control, light control, temperature control, automatic inspection and other humanized functions. What are these problems? We will organize the relevant instructions below for you.
First of all, let us understand the multi-chip combined light source used in LED street lamps. According to the current status of the LED street lamp market, the power of LED microcontrollers on the market is generally between 1 and 5W, and the luminous flux output is only a few hundred lumens. In order for LEDs to be used in general lighting on a large scale, the luminous flux of LED street light sources must reach thousands or even tens of thousands of lumens, and a single chip cannot achieve such a high light output. In order to meet such high light output requirements, a combination light source with multiple LED chips (usually 1W) has been adopted at home and abroad. So, what are the problems of using multi-chip combined light sources for LED street lights?
1. The production process of LED street lamp lighting is cumbersome, with low production efficiency and low reliability.
2. The design of the luminaire is limited by the number and arrangement of individual LEDs. It is difficult to balance the appearance and performance of lamps.
3. The secondary light distribution design of the luminaire is complicated, and it is difficult to meet the requirements of different lighting designs, which reduces the light efficiency of the luminaire.
4. Dozens of single-chip LEDs are installed in the same lamp. The photoelectric performance parameters of each LED chip must be consistent, otherwise the photoelectric performance and performance of the lamp will be greatly reduced.
5. During use, blind spots caused by partial failures are prone to occur, causing blind spots and increasing maintenance costs.
The above is about the problems that still exist in the use of multi-chip combined light sources for LED street lights. If you want to know more related instructions, you can follow our website for more consultation, or you can call to inquire.
