Like Fig. 7,8, shown in 9 and 10, be front schematic perspective view, back side schematic perspective view, decomposition texture sketch map and the cross section structure sketch map of the light source assembly of the high canopy lamp of LED of the utility model embodiment.
Led light source plate 1-7 is by the moulding of aluminium base welding led chip, and led light source plate 1-7 is fixed on the heat transfer plate 1-8 through screw, smears conduction estersil between led light source plate 1-7 and the heat transfer plate 1-8 to reduce the thermal contact resistance between led light source plate 1-7 and the heat transfer plate 1-8; Upward wiring board 1-6, led light source plate 1-7 also together are fixed on the base 1-9 to base 1-9 thereby heat transfer plate 1-8 seat is put; Be welded with the electric wire that links to each other with driver 10 on the electrical fitting 1-10 and be provided with electrical contact; Thereby electrical fitting 1-10 active card is contained in base 1-9 and goes up the electrical contact that makes said electrical fitting 1-10 in the preset draw-in groove and go up the connector that welds with said wiring board 1-6 and be connected; Guaranteed that through connector and this electrical activity connected mode of electrical contact light source assembly is connected with conducting between the external power source and is easy to dismounting and change, when being electrically connected of dismounting light source assembly 1 only need with electrical fitting 1-10 from base 1-9 preset draw-in groove extract and can break off with the connector of wiring board 1-6.
Can on base 1-9, preset to opening, on the heat transfer plate 1-8 with the correspondence position of directed opening on preset gib block, be convenient to heat transfer plate 1-8 and sit to put can make between connector and the electrical fitting 1-10 to the base 1-9 and be electrically connected exactly.In actual use; Electrical fitting 1-10 is a printed on both sides pcb board; Wherein simultaneously weld the electric wire that links to each other with driver 10 and be convenient to external cabling, another side is preset pad, can add the connector that forms on electrical contact and the wiring board 1-6 behind the scolding tin and be electrically connected.On structure, can think that electrical fitting 1-10 constitutes the part that light source assembly 1 is electrically connected; Certainly; On structure, can think that also electrical fitting 1-10 is not the part of light source assembly 1, but the bridge that is electrically connected between light source assembly 1 and the fitting structure.
Wiring board 1-6 is laid in led light source plate 1-7 periphery and is fixed on the heat transfer plate 1-8 through screw, is electrically connected through the welding electric wire between wiring board 1-6 and the led light source plate 1-7; In actual use, wiring board 1-6 can be a loop configuration, thus wherein the position for the hollow structure that adapts with led light source plate 1-7 geomery so that wiring board 1-6 saves the space around being set in led light source plate 1-7.In actual use, wiring board 1-6 is the pcb board that is printed on one side.
Reflector 1-5 is bonded on the led light source plate 1-7 with heat-resistant adhesive, and around the solid brilliant position that is used for fixing the LED wafer, the reflecting surface high polish of its inwall fully reflects with the light that the LED wafer is sent at the bottom of the hollow cup of reflector 1-5; Support 1-4 has the hollow structure of the rim of a cup geomery of an adaptation reflector 1-5, and said support 1-4 cover is detained led light source plate 1-7 and fixed through screw with heat transfer plate 1-8, and reflector 1-5 is passed by the hollow structure of support 1-4.
Face-piece 1-2 also has the hollow structure of the rim of a cup geomery of an adaptation reflector 1-5; Face-piece 1-2 cover fastens support 1-4 and clamps fixing; Diffuser 1-1 cover is detained said hollow structure and is clamped with face-piece 1-2; Diffuser 1-1 reflects the light of reflector 1-5 reflection and forms even, soft irradiation light, thereby thereby screwing to be connected through screw thread between face-piece 1-2 and the base 1-9 is received into inside with support 1-4, reflector 1-5, wiring board 1-6, led light source plate 1-7, heat transfer plate 1-8 and forms a stand-alone product.Helicitic texture between face-piece 1-2 and the base 1-9 has guaranteed to disassemble face-piece 1-2 apace, twists with said light source assembly 1 quick dismounting and change thereby support 1-4 is gone up fixed light source assembly 1 and the screw of heat sink assembly 3.Can screw thread screws between face-piece 1-2 and the base 1-9 to make things convenient at preset one section guiding curved surface on the base 1-9.Simultaneously screw mode, can on face-piece 1-2, some depressed parts of being affectedly bashful that are suitable for pointing be set according to hand-type for matching thread, thereby as unscrewing and impetus when screwing face-piece.
Leave one section relative sliding space between support 1-4 and the face-piece 1-2; Spring 1-3 is installed in said sliding space; And be placed in the upward preset ring-shaped groove of support 1-4 spring 1-3 fixing; Spring 1-3 can push support 1-4 through the reaction force of face-piece 1-2, thereby will outwards push up with the fixing heat transfer plate 1-8 of support 1-4 all the time, and heat transfer plate 1-8 is closely contacted with the light source fixed head 3-1 of heat sink assembly 3; The heat that led light source produces can be led away through lamp radiator sooner; Fully prolonged the service life of led light source, made that the movable connection structure between led light source assembly and heat sink assembly is compact more, guaranteed to flexibly connect do not influence down radiating effect, more convenient to operate, safety coefficient is higher.
In general; Light source assembly is not encapsulated as a product with light fixture as stand-alone product; Its structure generally is difficult to take into account the safe ready of electric wiring, the tight of quick and easy and radiator structure of fixed connection contacts, and the helicitic texture between the electrical contact of spring 1-3, electrical fitting 1-10, the connector of wiring board 1-6, face-piece 1-2 and the base 1-9 all is that light source assembly can be used as stand-alone product and realizes quick-replaceable basis.
Present embodiment is the indoor application light fixture, and good performance of heat dissipation and moulding are arranged, and the integral protection grade is not less than IP (water proof and dust proof grade) 20.The material of all exposed structures possesses certain corrosion-resistant, ageing resistace.
The high canopy lamp of the utility model other LED more of the same type has following advantage:
The high canopy lamp of the LED of the utility model utilizes copper heat pipe to combine the radiator structure of aluminium alloy radiating fin, has guaranteed better heat radiating effect.
The existing high canopy lamp of LED of the same type; Mostly adopt the radiator structure of aluminium alloy extruded section bar; Because the restriction of aluminium alloy extrusions heat-sinking capability needs to rely on the mode that increases section bar surface area and volume to satisfy the heat radiation requirement, thereby increases light fixture weight or technology difficulty; And the radiator structure of the utility model has alleviated the light fixture overall weight, satisfies the heat radiation requirement simultaneously.
The existing high canopy lamp of LED of the same type; Adopt the mode of fan forced convection to dispel the heat; This can increase environmental noise on the one hand; The life cycle of fan is restricting the service life of the high canopy light fixture of LED again on the other hand, and the heat sink assembly of the utility model particular design combines reflector under the situation of not using fan, to guarantee convection effects, and can obtain same even better radiating effect.
