Problems solved by technology

[0007] However, there are various problems in the above-mentioned scheme. A large number of heat conductors must be used for heat conduction. The heat conductor is mainly made of metal. Even if aluminum with good thermal conductivity and light weight is used, its weight is still large and the manufacturing cost is relatively high.
The heat dissipation efficiency of heat radiation is low, and the heat cannot be dissipated in time. The heat convection structure is complex, the processing is difficult, and the circuit is large, which increases power consumption.

Description

technical field [0001] The invention relates to the field of LED lighting lamps, in particular to a light-weight, high-efficiency, heat-dissipating LED lamp. Background technique [0002] LED lights have become a widely used light source because of their energy saving, durability, small size and environmental protection. When the LED lights are gathered together, if the heat cannot be dissipated in time, the junction temperature of the LED lights will increase significantly, which will result in reduced luminous efficiency and shortened service life of the LED lights. [0003] In order to solve this problem, various solutions have been proposed in the industry, and the following three are commonly used: [0004] 1. Heat conduction, that is, the heat is exported to the low-temperature environment through the heat conductor. The more commonly used means include setting heat dissipation fins, or supplementing the heat dissipation fins with low-temperature refrigerants to take ...
