Problems solved by technology

At present, in order to meet the needs of lighting, semiconductor lighting fixtures, especially street lighting fixtures, must be assembled and packaged with multiple high-power chips to meet the design requirements. The temperature rise cannot be effectively suppressed, and the junction temperature will be quickly dissipated in the air, which will directly affect the service life and luminous efficiency of the LED, and even burn the LED
At present, most application manufacturers use a single 1W high-power chip to directly fix the light source on the heat dissipation lamp body when they have not solved the heat conduction solution. This method is easy to dissipate heat due to the low power, but the luminous intensity is not enough. , the effective range is insufficient, and it cannot be used as a light source for elevated street lights, but we also know that most of the electric energy of the light-emitting diodes in the prior art will be converted into heat energy. For LED devices packaged with multiple high-power chips, the large dissipation Power, large calorific value and high light output efficiency cannot be solved by the heat dissipation method and material of a single 1W LED device. If the heat generated by the high-power packaged LED cannot be effectively dissipated in the In the air, the temperature of the high-power integrated package LED chip is easy to be too high, resulting in a serious drop in luminous efficiency, or even burning the light-emitting diode
At present, when high-power light-emitting diodes are assembled and packaged for street lighting, the problem of heat dissipation cannot be solved, so it cannot be adopted and implemented.
