The specific embodiment
As Figure 1-3, led lamp of the present utility model comprises two lamp bodies 100 and is used to install a fixed mount 200 of described lamp body 100.Each lamp body 100 is the truncated rectangular pyramids shape that the middle part is run through up and down.
See also Figure 45, each lamp body 100 comprises that transmissive mirror 80, that the lamp housing 10, of a Connection Bracket 200 is installed on these lamp housing 10 bottoms is installed on the radiator 30 between lamp housing 10 and the transmissive mirror 80 and is installed in light emitting diode module 40 on the radiator 30.One reflector 50 is installed between lamp housing 10 and the radiator 30, with the reflection of light that light emitting diode module 40 is sent and pass transmissive mirror 80, to reach the effect of illumination.
This lamp housing 10 is the truncated rectangular pyramids shape of hollow, comprises that a roughly rectangular top board 11 reaches from downward, the outward extending sidewall 12 of top board 11 4 edge tilt.These top board 11 middle parts are provided with a through hole 110, and top board 11 evenly is extended with six lugs 112 with fixedly connected radiator 30 towards through hole 110.These top board 11 bottoms are convexly equipped with plurality of fixed post 116 downwards with fixing reflector 50 in the periphery of through hole 110.Outer surface one corner of the lamp housing 10 i.e. bottom, junction of two sidewalls 12 is provided with the connecting plate 13 of a parallel top board 11 and the dividing plate 14 that extends vertically upward from connecting plate 13 inside edges.This connecting plate 13 is provided with through wires hole 133 and fixing hole 131, is used for Connection Bracket 200 so that lamp body 100 is fixed on fixed mount 200.Vertical respectively connecting plate 13 and the dividing plate 14 of connecting of some triangle stiffeners 16 is with the intensity of reinforced company's fishplate bar 13.One lid, 18 correspondences are installed on the outer ledge of connecting plate 13 and dividing plate 14, and form the chambers of a sealing jointly to accommodate the electric wire (scheming not show) that is connected lamp body 100 and fixed mount 200 with connecting plate 13 and dividing plate 14.
This reflector 50 is hollow truncated rectangular pyramids shape and similar to lamp housing 10 shapes.This reflector 50 comprises that a top board 51 reaches from downward, the outward extending sidewall 52 of top board 51 4 edge tilt.Top board 51 middle parts are provided with a through hole 510 with sheathed radiator 30 of correspondence and light emitting diode module 40.The end face of this top board 51 convexes with the fixed leg 116 of four fixed legs 516 with corresponding lamp housing 10 in through hole 510 peripheries, the fixed leg 516 that some screws (figure does not show) pass reflector 50 is screwed in the fixed leg 116 of lamp housing 10, so that reflector 50 is fixed on the top board 51.The wherein junction of two sidewalls 52 of this reflector 50 forms the dividing plate 14 of a dividing plate 54 with corresponding lamp housing 10.
Please consult Fig. 5 once more, during lamp body 100 assemblings, earlier reflector 50 correspondences are fixed on lamp housing 10 inboards; The radiator 30 that light emitting diode module 40 will be installed then passes the through hole 510 of luminous plaque 50, the upper end of radiator 30 is resisted against on the lamp housing 10, the lug 112 that some screws pass lamp housing 10 is screwed on the connection rib 35 of radiator 30, thereby radiator 30 is installed on the lamp housing 10; At last, transmissive mirror 80 is mounted to the bottom of lamp housing 10, its lug 812 is resisted against the bottom of radiator 30, and the packing ring 60 by a ring-type be sticked on transmissive mirror 80 for screw (figure does not show) pass packing ring 60, transmissive mirror 80 screws togather with the connection rib 35 of radiator 30.One packing ring 70 corresponding with transmissive mirror 80 outward flange shapes is sticked and in the bottom of transmissive mirror 80 and by screw (figure does not show) packing ring 70 is fixed on the lamp housing 10.
Please consult Figure 23 once more, fixed mount 200 comprises a cup-shaped main part 210 and a loam cake 220.This main part 210 is the hollow setting, comprises all around a wall 211 and a base plate 213.This base plate 213 is provided with a centre bore 215 to connect a lamppost (figure does not show).These loam cake 220 rectangular settings, its two relative angle is respectively equipped with a through wires hole 223 and double-screw bolt 221, with the through wires hole 133 and the fixing hole 131 of the connecting plate 13 of corresponding each lamp body 100.Each lamp body 100 is mounted to lid 18 on the lamp body 100 after being fixedly mounted on the fixed mount 200 again.
When using this led lamp, after light emitting diode 44 energisings, the heat of its generation conducts in the entire radiator 30 via heat-conducting block 39, thereby has avoided the accumulation of heat.Heat is distributed to the air of the through hole 37 that is arranged in radiator 30 via the fin 33 of radiator 30.Because the through hole 37 of radiator 30 is connected the external world up and down with the through hole 810 of the through hole 110 of lamp housing 10, transmissive mirror 80, makes the air that is heated at radiator 30 middle parts expand into the less hot-air of density, rising is passed lamp housing 10 and is left radiator 30; The through hole 810 that the cold air that be positioned at radiator 30 bottoms this moment passes transmissive mirror 80 moves up, and enters radiator 10 inside; This part absorption of air heat is transformed into hot-air once again afterwards, thereby realizes cross-ventilation constantly, constantly removes the heat of led lamp.And because light emitting diode module 40 around radiator 30 outer wall settings, can be adjusted light by reflector 50 reflections, penetrate, reach a preferable illuminating effect from transmissive mirror 80.
In sum, the radiator 30 of the utility model led lamp is arranged on the middle part and the up/down perforation of lamp body, the heat that the light emitting diode 40 that is sticked around radiator 30 can be produced promptly transfers to entire radiator 30, rapidly heat is dispelled the heat to extraneous air by free convection up and down, and then improved the radiating efficiency of radiator 30; And because the connecting plate 13 of the end by lamp body 100 is fixed on the fixed mount 200, make lamp body 100 under the situation of the circulation of air that does not influence middle part radiator 30, realize its installation well, and can adjust the quantity of the lamp body 100 on the fixed mount 200 according to the actual needs.
