Problems solved by technology

However, the thermal expansion coefficient of ordinary aluminum alloys is very different from that of LED chips. When the temperature changes greatly or the packaging operation is improper, thermal distortion will easily occur, causing chip defects and lower luminous efficiency.
Since the LED brightness increases with the increase of the driving current, for higher brightness LEDs, the ordinary aluminum alloy casing can no longer meet its heat dissipation requirements; therefore, it is necessary to develop a new LED lamp casing to improve the heat dissipation speed of the lamp
