In the solar LED street light, the chip is equivalent to the human brain, serving as the central control in the entire lighting system. The solar street light chip faces a mismatch of thermal expansion coefficients between the chip, silicone (or resin), metal support, and leads. This mismatch is more pronounced in regions with significant temperature variations, such as plateaus. The expansion and contraction exacerbate, leading to excessive internal pressure. When the internal pressure is too high, it increases the distance between the LED wire points, significantly reducing the lifespan of the wires. It may also lead to some solder points becoming detached, and in severe cases, the LED chip may experience delamination and peeling.
Another significant effect of temperature changes on solar LED street lights is the operational issues of the driving device under extreme cold conditions. From the current market performance, there may be occurrences when the device fails to turn on at very low temperatures.
Bitpott is a manufacturer that integrates research, production, and sales of solar street lights. The main products include solar street lights, solar landscape lights, courtyard lights, LED street lights, high pole lights, and thousands of other products. These products have successively passed ISO9001 international quality system certification, CCC certification, CE certification, and international standard product mark certification.
