The specific embodiment
Shown in Fig. 1-2, led lamp of the present invention comprises that some light emitting diode module 100, are used to settle the radiator 200 of these some light emitting diode module 100, are installed on the lampshade 300 that some heat pipes 500, in this radiator 200 are installed on these radiator 200 middle parts, and a transmissive mirror 400 that is fixed on lampshade 300 bottoms.
See also Fig. 3 and Fig. 4, above-mentioned radiator 200 is the aluminium extruded type radiator, and it comprises the heat carrier 230 of a hollow tube-shape and the some radiating fins 240 that are connected with heat carrier 230.This heat carrier 230 comprises a radiating part 235 and an endothermic section 238.The radiating part 235 of this heat carrier 230 is extended with four connection ribs (figure is mark not) in axial direction from the surface.Each connection rib top is equipped with an installing hole to connect a lamp holder (figure does not show) by connector, and this lamp holder is a standard component, can buy from the market.These some radiating fins 240 extend to the excircle radiation from the outer surface of the radiating part 235 of this heat carrier 230, wherein are extended with three radiating fins 240 on each connection rib.Each radiating fin 240 extends parallel connection rib along the axial direction of heat carrier 230.At week of this heat carrier 230 even some short radiating fins 240 spaced apart upwards, the length that these some short radiating fins 240 make progress in these heat carrier 230 footpaths than around radiating fin 240 short, and axial length to.Form some gas channels between the adjacent radiating fin 240 for circulation of air.This heat carrier 230 has a columniform inner surface 254, is provided with some grooves 256 on inner surface 254 equably, with ccontaining heat pipe 500.Described groove 256 extends axially along heat carrier 230, and runs through connection endothermic section 238 and radiating part 235.Each heat pipe 500 is linearly, is contained in the groove 256 of the correspondence of heat carrier 230, and connects the radiating part 235 and endothermic section 238 of heat carrier 230.
Please consult Fig. 1 and Fig. 2 again, above-mentioned lampshade 300 is bowl structure, has a concave surface and is provided with a perforate 310 at this concave surface middle part, and the endothermic section 238 of heat carrier 230 is contained in this lampshade 300 by this perforate 310.The light that this lampshade 300 is used for light emitting diode module 100 is sent is towards a default direction reflection.
Described transmissive mirror 400 is made by suitable materials such as plastics, glass usually, to reach the effect of printing opacity.This transmissive mirror 400 is installed in the bottom of lampshade 300, and the cavity of forming a sealing with lampshade 300 is with ccontaining light emitting diode module 100 and stop objects such as dust, insect to enter the lighting effects that lampshade 300 influences light emitting diode module 100.
The surface that above-mentioned light emitting diode module 100 is installed on the endothermic section 238 of heat carrier 230 forms the light source of a three-dimensional to increase the illumination effect of led lamp.Each light emitting diode module 100 comprises a circuit board 120 and is fixed on some light emitting diodes 110 on this circuit board 120.This circuit board 120 is provided with circuit (figure does not show), to electrically connect with respective leds 110.Circuit on each circuit board 120 passes radiator 200 or other method and a power supply by electric wire (figure does not show) and electrically connects.
