Abstract

The utility model discloses an LED light source module. A cooling fin, a circuit board and a fixing plate are connected in sequence; the cooling fin is connected with the circuit board; the circuit board is fixed on the cooling fin by the fixing plate through a cored screw to perform glue filling and sealing; the cooling fin is sectionalized; and ventilating fixed holes are formed in the upper part and the lower part of the module. The LED light source module adopting the technical scheme has the advantages of simple structure and good lighting effect.

Description

The led light source module

Technical field

The utility model relates to the led light source module of a kind of road high-power illumination system.

Background technology

What the led light source majority that uses in the road lighting at present adopted is whole integrated, the main fin heat radiation of leaning on light fixture of its heat radiation, and led light source itself is non-watertight, and light source is positioned over lamp interior, reaches waterproof and printing opacity by the glass face shield.Such lamp interior air can not circulate, and light efficiency is low.

Summary of the invention

In order to overcome the led light source heat dissipation problem, the utility model provides a kind of led light source module, and this led light source modular structure is simple, lighting effect good.

The scheme that its technical problem that solves the utility model adopts is: a kind of led light source module, radiating fin, wiring board, fixed head are linked in sequence, it is characterized in that: radiating fin connection line plate, fixed head is fixed in wiring board on the radiating fin by cored screw, carries out sealant pouring and sealing.

Described radiating fin is a segmented, described led light source module the ventilation fixing hole arranged up and down.

Specifically, in the led light source module, radiating fin is segmentation, is positioned at the top of module.In the middle of the module then is the copper base circuit board, and the copper base circuit board closely is connected with radiating fin by heat-conducting silicone grease, and led light source is fixing in the circuit board.The bottom of module is a fixed head, and copper base circuit board and radiating fin are fixed.Distributed above the module and be used for connecting up and down and the hole of ventilation usefulness.When led light source was driven power supply and lights, light source can produce a large amount of heats.Heat is transmitted on the radiating fin through heat-conducting silicone grease by the copper base circuit board, heat above the radiating fin of segmentation at this moment can be taken away heat by air all around, because the hole that distributes on the module can provide air to circulate up and down for the heat radiation of fin approach, fin at this time utilizes the air heat radiation to reach optimum effect, has solved the led light source heat dissipation problem fully.The led light source module carries out sealant pouring and sealing to be handled, and degree of protection reaches IP67, can be used in combination out of doors, and the air of circulation can contact with it fully, and the heat that the led light source module produces can be taken away by air rapidly.

Led light source module common in the utility model and the prior art is compared, and it has the following advantages:

Because led light source module described in the utility model, it is with radiating fin connection line plate, and fixed head is fixed in wiring board on the radiating fin by cored screw, carries out sealant pouring and sealing, the led light source module that this technical scheme constituted has advantage simple in structure, that lighting effect is good.

The specific embodiment

The utility model will be further described below in conjunction with accompanying drawing.

Extremely shown in Figure 5 according to Fig. 1, led light source module described in the utility model, its radiating fin 1, wiring board 2, fixed head 4 are linked in sequence, radiating fin 1 connects described wiring board 2, be connected with the electric power connection line 5 that aims at led light source 3 power supplies on the heat sink 2, fixed head 4 is fixed in wiring board 2 on the radiating fin 1 by cored screw, during led light source 3 be to be fixedly installed on the radiating fin 1, carry out sealant pouring and sealing subsequently.Fixed head 4 is fixed in wiring board 2 on the radiating fin 1 by cored screw, carries out sealant pouring and sealing.

During this time, radiating fin 1 is a segmented, and module has the ventilation fixing hole up and down.The degree of protection of the led light source module after the sealing reaches IP67.

Fig. 5-1, Fig. 5-2, Fig. 5-3 and Fig. 5-4 are front view of the present utility model, vertical view, upward view and left view respectively in turn.

Wherein, be to lump together successively in proper order up and down in the structure of anticipating shown in Fig. 1 by the radiating fin of Fig. 2, the wiring board of Fig. 3, the fixed head of Fig. 4, being locked through the aperture on the module with hollow brass screws forms the led light source module of an integral body.At last the led light source module is carried out encapsulation process, draw power supply wiring, form a led light source module that waterproof is independently used, the led light source module that this technical scheme constituted has advantage simple in structure, that lighting effect is good.
