A kind of high-powered LED lamp bar
Affiliated technical field
The utility model relates to a kind of LED lamp bar, particularly a kind of high-powered LED lamp bar.
The LED lamp is because of characteristics such as its low-power consumption, long-lives, be widely used in the various fields in life by people, particularly LED lamp bar is used for various ornament lamps and is widely used, because LED lamp bar uses for the decoration that is suitable for different shape, but be the technical problem that the high-powered LED lamp bar needs to be resolved hurrily for the heat dissipation problem of high-power LED lamp bar always.
Summary of the invention
For solving the heat dissipation problem of high-power LED lamp bar, the utility model designs a kind of high-powered LED lamp bar structure, by improvement PCB structure, heat dissipation metal lamp bar housing is directly dispelled the heat to the LED lamp, thermoelectric separated structures has guaranteed the normal operating temperature of LED lamp, improves the service life of high-powered LED lamp bar.
The utility model realizes that the technical scheme that goal of the invention adopts is, a kind of high-powered LED lamp bar, comprise: lamp bar housing, LED lamp and PCB circuit board, lamp bar housing is the heat dissipation metal housing, LED lamp and PCB circuit board are arranged in the lamp bar housing, and the sealing inserts is arranged on LED lamp and PCB circuit board sealing and fixing in the lamp bar housing.On the outer surface of lamp bar housing, be provided with one group of radiating fin.Lamp bar housing is the aluminium alloy radiating shell.
The beneficial effects of the utility model are, and are simple in structure, with low cost, easy to install, advantages such as safe and reliable and long service life.
Below in conjunction with accompanying drawing the utility model is elaborated.
Description of drawings
Accompanying drawing 1 is the utility model schematic diagram.
Accompanying drawing 2 is an accompanying drawing 1A-A amplification view.
In the accompanying drawing, 1 lamp bar housing, 2LED lamp, 3PCB circuit board, 4 sealing inserts, 5 radiating fins.
The specific embodiment
Referring to accompanying drawing, a kind of high-powered LED lamp bar, comprise: lamp bar housing 1, LED lamp 2 and PCB circuit board 3, lamp bar housing 1 is the heat dissipation metal housing, LED lamp 2 and PCB circuit board 3 are arranged in the lamp bar housing 1, and sealing inserts 4 is arranged on LED lamp 2 and PCB circuit board 3 sealing and fixing in the lamp bar housing 1.
During use, the through hole that the heat that LED lamp 2 produces sees through PCB circuit board 3 directly sheds by lamp bar housing 1, has solved the heat dissipation problem of high-powered LED lamp bar.
For further improving the radiating effect of lamp bar housing 1, on the outer surface of lamp bar housing 1, be provided with one group of radiating fin 5.Radiating fin 5 has increased the area of dissipation of the outer surface of lamp bar housing 1 greatly.Lamp bar housing 1 can adopt the aluminium alloy radiating shell simultaneously.
