Problems solved by technology
It has become a trend to replace incandescent lamps and fluorescent lamps with LED semiconductor solid-state light sources. However, due to the limitation of LEDs' own characteristics, the increase in operating temperature will cause serious light attenuation and affect the service life. It is even more necessary to have a radiator with better heat dissipation to quickly dissipate the heat generated by the LED chip when it is working
The radiator of the existing single high-power LED lighting lamp usually uses a light source that densely arranges one or more LED chips together and then fixes it on the aluminum alloy plate, and the heat sink naturally dissipates heat through the aluminum alloy plate. The conduction to the edge is relatively far away. Since the LED chips are densely packed together, it is difficult to quickly dissipate the accumulated heat. Long-term work will cause the temperature of the LED chip to exceed its operating temperature, thus affecting the lighting effect of the LED chip and service life

The invention aims at providing a heat radiator for a single-particle super-power LED (light emitting diode) light source illuminating lamp. In the lamp, single-color chips are combined in series and in parallel, silica gel is coated on the surface of the radiator for encapsulation, a lens is arranged externally, and a metal substrate serves as heat sink; by utilizing a principle that a proper working solution added into a vacuum cavity can quickly conduct heat, the substrate heat sink is directly utilized as one edge of the bottom of the vacuum cavity to serve as a combination of a heating end, heat produced when the substrate heat sink works on the LED chip can be quickly scattered to the upper and lower surfaces of the lamp; and the LED can radiate heat by utilizing the sufficient radiating face on the surface of the lamp, so that the heat can be quickly scattered.
Description
technical field [0001] The invention relates to a radiator for a single ultra-high-power LED light source lighting lamp technical background [0002] Light-emitting diodes, referred to as LEDs, have the advantages of small size, low energy consumption, high brightness, and low-voltage operation, and are widely used in various industrial fields. It has become a trend to replace incandescent lamps and fluorescent lamps with LED semiconductor solid-state light sources. However, due to the limitation of LEDs' own characteristics, the increase in operating temperature will cause serious light attenuation and affect the service life. It is even more necessary to have a heat sink with better heat dissipation to quickly dissipate the heat generated by the LED chip when it is working.
