Description
Technical field
The utility model relates to a kind of power pack, particularly relates to a kind of LED power pack.
Background technology
Development along with the LED technology; Increasing illuminating lamp is replaced by the LED lamp, but LED is the components and parts that caloric value is bigger, and the luminous power supply of driving LED also is a very important heater; In the course of work of LED lamp; If the heat that its driving power is not produced is not handled, not only can have influence on LED lamp whole useful life, even make it can't operate as normal.Traditional LED lamp adopts the aluminium extruded housing more, directly is put into the inside to circuit board, adopts encapsulating to realize heat radiation and sealing as heat-conducting piece; Can make the quality of power supply heavier like this; Because the conductive capability of encapsulating is poor, can cause the heat in the power pack not distribute timely, influence the environment for use and the life-span thereof of power supply; And if use heat-conducting glue preferably, the cost of power supply is increased greatly.
The utility model content
The utility model provides a kind of simple in structure in order to address the above problem, perfect heat-dissipating, the LED power pack that the waterproof anti-explosion function is strong.
The technical scheme of the utility model is:
A kind of LED power pack; The box body of the side's of comprising tubular and the end cap at two ends; The box body madial wall is provided with a heat conduction aluminum strip, is respectively equipped with two corresponding PCB holddown grooves on two relative sidewalls in the box body, and pcb board is fixed in the PCB holddown groove; Heating electronic component on the pcb board is fixedly connected with the heat conduction aluminum strip, and the end cap junction at box body and two ends is provided with seal gasket.
Said box body one side is provided with screwing through hole, the heat conduction aluminum strip through the screw in the screwing through hole on the madial wall of box body.
The material of said box body is an aluminium alloy, and layer of oxide layer is contained on the surface of box body.
The lateral surface of said box body is provided with the heat radiation raised item.
The end cap at said box body two ends is provided with the extension, and the extension is provided with and installs and fixes the hole.
The beneficial effect of the utility model:
1, the utility model is simple in structure, and is succinctly general, is mainly used in 50 ~ 200W large power supply, and two PCB holddown grooves that have on the box body play fixedly pcb board, can prevent effectively that pcb board from moving in box body.
2, the utility model heat conduction, waterproof, explosion-proof effect are good; The heat conduction aluminum strip that is provided with in the box body is fixed with the main heating electronic devices and components on the pcb board, and is close to through screw and box body; Make the heat of generation directly pass on the box body; Reach the purpose of dispelling the heat preferably,, realized integral waterproofing, the explosion prevention function of power supply through the seal gasket between box body and the two end cap.
3, need not encapsulating in the power pack, the whole quality of power pack is lightened, reduced cost; The heat radiation raised item that the power pack outside is provided with, the more heat that can shed, heat dissipation capacity is up to 50W; Make power work stable more, reliable, cost reduces, and helps producing in enormous quantities.

Embodiment
Like Fig. 1, Fig. 2, Fig. 3, Fig. 4, shown in Figure 5, a kind of LED power pack, the box body 1 of the side's of comprising tubular and the end cap 2 at two ends; Box body 1 inside is provided with a heat conduction aluminum strip 7, is provided with two PCB holddown grooves in the box body 1, and the heating electronic component 11 on the pcb board is fixedly connected with heat conduction aluminum strip 7; Box body 1 one sides are provided with two screwing through hole 9; Be used for fixing heat conduction aluminum strip 7, the lateral surface of box body 1 is provided with heat radiation raised item 3, has increased area of dissipation; Oxidation processes has been done on its surface, can make heat dissipation capacity up to 50W.
The pcb board 6 of LED power supply; Its input and output power line is installed in the box body 1 through the through hole 8 on the box body two end cap, and pcb board 6 is fixed in the box body 1 through holddown groove 10, and the main heating electronic devices and components are fixed on heat conduction aluminum strip 7 and the pcb board 6; And be close to through screw and box body; Make the heat of generation directly pass to box body 1, play the effect of heat conduction efficiently, heat radiation, make power pack need not encapsulating and just can reach better radiating effect.
Seal gasket is located at the junction between box body 1 and the two end cap 2, realizes integral waterproofing, the explosion prevention function of power pack.
Install and fix hole 5 on LED power pack end cap 2 extensions, can be used for the fixed power source box.
