AI Technical Summary

Problems solved by technology

The working characteristics of light-emitting diodes (LEDs) are low voltage and high current, and the heat generated by high-current lamps will be large, and the temperature of lamps has a direct impact on the luminous efficiency and life of LEDs. How to solve the heat dissipation problem of LED lamps, reduce the temperature of lamps, and improve The luminous efficiency and service life of lamps are still a major problem restricting the development of LED light sources. In order to solve the heat dissipation problem of LED lamps on the market, the common method is to increase the heat dissipation area and design the outer surface of the lamp for heat dissipation. Good air convection, this design has poor heat dissipation effect, resulting in low luminous efficiency of the lamp and affecting the life of the lamp

For some lamps such as industrial and mining lamps used in high places, because the heat dissipation area is only blindly increased, it will inevitably lead to an increase in the weight and cost of the lamps, resulting in inconvenience in the installation of the lamps, and there are problems such as potential safety hazards.

[0003] In addition, many of the current LED lamps have a structure in which the lamp beads are connected to the aluminum substrate, the aluminum substrate is connected to the base plate, and the base plate is connected to the heat dissipation structure. This creates a multi-layer thermal resistance in the middle, which affects the heat dissipation of the lamp. Most LED lamps can only do low power cooling
