Description

technical field [0001] The invention belongs to the technical field of LED lamps, and in particular relates to a heat-absorbing, decompressing, heat-conducting and heat-insulating structure for liquid quantum dot LED lamps. Background technique [0002] As a high-efficiency solid-state light source, light-emitting diodes (LEDs) are considered to be one of the most promising products in the 21st century due to their low energy consumption, high luminous efficiency, small size, safety and reliability, environmental protection, and simple structure. Quantum dots have Unique optical and electrical properties such as wide absorption, narrow emission, and large quantum yield. When its physical size is smaller than the Bohr radius of excitons, it has unique optical and electronic properties due to the quantum size effect. Its optical The properties depend largely on the particle size of the quantum dots, regardless of the composition. By changing the size of the quantum dots, the e...

Problems solved by technology

[0003] Since most of the energy of the liquid quantum dot LED light-emitting chip is converted into heat energy, the current existing liquid quantum dot LED lamps do not have a good heat dissipation effect, and a large part of the heat dissipated is still transmitted to the quantum dots, and the temperature is too high. The luminous effect is invalid, and the poor heat dissipation performance of the lamp will affect the service life and luminous efficiency of the lamp

Therefore, it is not practical in the market
