Background technique

LED (Light Emitting Diode), that is, semiconductor electric light source, light-emitting diode, also known as semiconductor lamp, is a kind of electric light source without filament, which directly converts electrical energy into light energy.

LED lights have the characteristics of energy saving and long life, avoiding the trouble of changing bulbs frequently, and are favored by more and more users. However, the heat dissipation problem of LED lights is also a key issue, which seriously affects the light efficiency and life of LED light sources. For traditional LED lamps, the lampshade used for concentrating light is generally closed. Such a lampshade cannot dissipate heat from the substrate, resulting in low heat dissipation efficiency, resulting in high temperature of the LED light source and power supply, which affects the LED light. efficacy and lifespan.

A plurality of cooling holes 122 are arranged in parallel in each interval, and the cooling holes 122 may be square or oval.

The lampshade 140 includes a connecting plate 142 , a plurality of reflective cups 141 connected to the connecting plate 142 and a radiator 150 connected to the connecting plate 142 . The heat sink 150 is composed of multi-layer mesh sheets. The reflective cups 141 accommodate the LED lamp beads 111 in one-to-one correspondence, and the connecting plate 142 and the reflective cups 141 are connected with light exit holes 1421 corresponding to the reflective cups 141 one-to-one. A lens is also stuck in the light exit hole 1421 .

A pipe 1422 is connected between the connecting plate 142 and the base plate 110, and the pipe 1422 may be a circular pipe, a square pipe or an oval pipe, preferably a circular pipe. One end of the pipe 1422 passes through the connecting plate 142 , and the other end of the pipe 1422 passes through the through hole 112 of the substrate 110 . The opening of the end of the pipe 1422 connected to the connecting plate 142 is larger than the opening of the end of the pipe 1422 connected to the substrate 110 . The connecting surface of the pipe 1422 and the connecting plate 142 is coated with thermal silica gel, and the connecting surface of the pipe 1422 and the substrate 110 is also coated with thermal silica gel.
