Let's take a look at the common problems of poor quality LED street lights.
1. Configure the virtual label
The fiery heat of adjustable LED street light is also accompanied by the reduction of price profits. The fierce competition has also led many merchants to start to have the parameters of smashing and smashing the standard products. This is also caused by repeated price comparisons by customers, requiring low prices, and also with some manufacturers. Related to the practice.
2. Counterfeit chips
The core of LED luminaires is the chip, which directly determines the performance of the luminaire! However, some unscrupulous merchants take advantage of the customer's unprofessionalism. From the perspective of cost, the use of low-cost chips enables customers to purchase low-quality products at high unit prices, causing direct economic losses and causing serious quality hazards to LED lights.
3. The design of the light distribution system of the street lamp is unreasonable.
In terms of optical design, if the design of the light distribution system of the street lamp is unreasonable, the lighting effect is not satisfactory. In the test, there will be problems such as "light under the light", "black under the light", "zebra crossing", "uneven illumination", "yellow circle" and so on.
4. Poor heat dissipation design
In terms of heat dissipation design, for every 10 degrees increase in the PN junction temperature of the LED chip, the lifetime of the semiconductor device is multiplied. Due to the high brightness requirements of LED street lights, the use environment is harsh. If the heat dissipation is not well solved, the LED will be aging quickly and the stability will be reduced.
