Description

Bionic honeycomb type LED radiator

Technical Field

The utility model relates to the technical field of radiators, in particular to a bionic honeycomb type LED radiator.

Background

Semiconductor Light Emitting Diodes (LEDs) also generate heat during operation, which depends somewhat on the overall luminous efficiency. Under the action of external electric energy, the radiation recombination of electrons and holes generates electroluminescence, and the light radiated near the PN junction can reach the outside (air) only through the semiconductor medium and the packaging medium of the chip (chip). And the current injection efficiency, the radiation luminescence quantum efficiency, the chip external light extraction efficiency and the like are synthesized, and only 30-40% of input electric energy is converted into light energy, and the rest 60-70% of energy is mainly converted into heat energy in a non-radiation composite generated lattice vibration mode.

Generally, whether the LED lamp works stably or not, the quality is good, the heat dissipation of the LED lamp and the lamp body is very important, the heat dissipation of the high-brightness LED lamp in the market usually adopts natural heat dissipation, and the effect is not ideal. The LED lamp manufactured by the LED light source consists of an LED, a heat radiation structure, a driver and a lens, so that heat radiation is also an important part, and if the LED cannot radiate well, the service life of the LED can be influenced. Currently, due to technical limitations, the photoelectric conversion efficiency of LEDs is still low, and most of the electrical energy is converted into thermal energy. Because the working characteristics of the semiconductor device are extremely sensitive to temperature, if heat is not timely dissipated, the higher the temperature of the LED light source is, the lower the luminous efficiency of the LED is, and the service life of the LED lamp is influenced by light attenuation. Existing LED heatsinks typically include a mounting substrate, thermally conductive posts, and heat dissipating fins. However, such design still has the problem that the fin heat dissipation area is small, and the heat dissipation effect is not ideal. Such as the product currently commercially available, the network links are: http:// www.etongfeng.com/item.phpid= 43688566546. Therefore, it becomes very important for the LED heat dissipation design.
