Detailed description of the invention
Below in conjunction with specific embodiment and accompanying drawing, the utility model light source module is described in further detail.
Refer to Fig. 1, in an embodiment, the circuit board 53 that light source module of the present utility model mainly comprises a radiator 54 and is attached on radiator 54, circuit board 53 is also disposed with the light guide 51 be substantially rectangle and rectangle baffle 52.
Light guide 51 upper surface is formed with multiple lens 511, and lower surface is formed with at least two locating dowel (not shown).Baffle 52 tightly sticks on light guide 51, it is formed with the through hole mated with lens.This baffle 52 preferably adopts stainless steel, for the protection of lens 511, improves the impact strength of light source module, and improves the weatherability of lens environment out of doors.Radiator 54 comprises a heat-conducting plate be substantially rectangle 541.Circuit board 53 is fixed between light guide 51 and heat-conducting plate 541, is provided with the LED light source 532 corresponding with multiple lens 511.In the present embodiment; circuit board 53 and heat-conducting plate 541 are formed and the suitable locating hole of locating dowel on light guide 51 respectively; and by locating dowel through the also fastening successively of corresponding locating hole; can either ensure that lens 511 on light guide 51 and LED light source are accurately located, by fixed screw 57, light guide 51, baffle 52, circuit board 53 and heat-conducting plate 541 be tightened together again.
In order to realize sealing, light guide 51 periphery can integrally extend backplate perpendicular to light guide or be formed with groove, and heat-conducting plate 541 is formed the groove corresponding with the backplate of light guide or groove and wall, thus light guide 51 is buckled in after on heat-conducting plate 541, be formed with the space (host cavity) for holding sealing ring 55 between the two.In the present embodiment, sealing ring 55 adopts water-proof silica-gel.In addition; the correspondence position of light guide 51 and baffle 52 is formed with multiple fixing hole; circuit board 53 dual-side is formed with multiple arc notch 531 corresponding with fixing hole on light guide; the shape of water-proof silica-gel 55 and the mating shapes of circuit board 53 outside; and be enclosed within circuit board 53 outside, guarantee that fixed screw 57 is positioned at outside water-proof silica-gel 55.When baffle 52, light guide 51 and circuit board 53 are fixed on after on heat-conducting plate 541 by fixed screw 57; water-proof silica-gel 55 is squeezed tightly between at light guide 51, between circuit board 53 and heat-conducting plate 541; now water-proof silica-gel 55 can produce distortion because of pressurized; gap sealing between light guide 51 and heat-conducting plate 541 is got up; ensure that circuit board 53 and LED light source can not make moist, guarantee light source life.
In the present embodiment, radiator 54 mainly adopts the aluminium section with certain bending, its except comprise one tightly stick in circuit board lower surface, except the heat-conducting plate 541 that is rectangle, also comprise and be basically perpendicular to two piece of second heat transfer plate 542 that heat-conducting plate integrally extends and the 3rd heat transfer plate 543 coupled together by the end of described two piece of second heat transfer plate from the dual-side of heat-conducting plate 541 lower surface.Wherein the length of the second heat transfer plate 542 is less than heat-conducting plate 541, thus the 3rd heat transfer plate 543 covering part heat-conducting plate 541, make the two ends of heat-conducting plate 541 in the state of stretching out, the heat sink benefits of this structure in improving radiating efficiency, strengthening the intensity of radiator, and effectively prevents dust, leaf, sandstone, bird dung long-term accumulated portion or inside on a heat sink.
In addition, please also refer to Fig. 2, circuit board 53 is also formed with the pad 538 for connecting power line 70.For convenience of describing, the one side being provided with multiple LED light source of circuit board 53 being defined as first surface, the one side opposing with first surface is defined as second.In the present embodiment, the position near one end on the first surface of circuit board 53 is provided with pad 538.U-shaped breach 539 is formed near the end of pad 538.
Please also refer to Fig. 3, position relative with U-shaped breach 539 on heat-conducting plate 541 is formed with string holes 532, after one end of power line 70 is connected with the corresponding pad 538 of circuit board 53, bend from U-shaped breach 539, extend towards string holes 532, and stretch out from string holes 532, be exposed to light source module outside, be connected with a connection-peg 78.For reaching the object of waterproof and moistureproof sealing, between power line 70 and string holes 532, be provided with silica gel plug assembly or sealing-plug 59.
In other embodiments, available one is formed in opening (through hole) near pad 538, that can expose string holes 532 replaces U-shaped breach.
Especially, heat-conducting plate 541 has test through hole 5518, in test through hole 5518, be plugged with waterproof bolt 5519.The space that test through hole 5518 surrounds with light guide 51, heat-conducting plate 541 and water-proof silica-gel 55 communicates.During test, the syringe needle of test syringe is inserted on waterproof bolt 5519, then light source module is put into water tank, inflating in light source module with test syringe.After extracting syringe needle, see whether each gap place of light source module has bubble to overflow, thus judge water resistance.Preferably, heat-conducting plate 541 is also formed with groove 5517 in the one side of circuit board.The space that groove 5517 is communicated with test through hole 5518 and is formed between circuit board and heat-conducting plate, such as but not limited to the path of power line 70 process---such as relative with U-shaped breach 539 and near or by the position of string holes 532.Be communicated with test through hole 5518 and wire casing 5415 or wire casing 5416 or be connected to the path of power line 70 process.So, the air entered from test through hole 5518 along the void diffusion of power line and circumferential component, thus can guarantee that the air injected in light source module enough tests use, guarantees the accuracy of testing.Because waterproof plug is squeezed state, the pin hole that rear waterproof plug extracted by syringe needle can close automatically, and light source module still can keep good waterproof moisture-proof effect.
In other embodiments, pad also can be arranged on circuit board towards in the one side of heat-conducting plate.In other embodiments, other light sources can be adopted to replace LED light source.
Although carry out in conjunction with above specific embodiment description of the present utility model, those skilled in the art can carry out many replacements, modifications and variations, be apparent according to above-mentioned content.Therefore, all like this substitute, improve and change be all included in the spirit and scope of attached claim.
