The specific embodiment
Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
Referring to figs. 1 through Fig. 3, an embodiment of a kind of LED light fixture of the present utility model is proposed, be connected with from the bottom to top holder structure, radiator, LED light source assembly, diffuser 500 in turn.Holder structure comprises lamp holder nut 100, the bulb socket 200 being connected with lamp holder nut 100, radiator comprises heat dissipation base 300, is located at the light source mounting disc 400 of heat dissipation base 300 upper ends, light source mounting disc 400 centers, upper surface are provided with light source cavity 403, light source cavity 403 center is provided with wire hole 404, the light source mounting disc 400 sides circular radiating ring that extends outwardly out, heat dissipating ring is provided with some heat radiation through holes 401, heat radiation through hole 401 extends the second radiating fin 402 down, and diffuser 500 is installed and is fixed on light source cavity 403 by bonding way.
Bulb socket 200 lower port are connected with the lamp holder nut 100 of being made by conductive material with spiro connection structure, bulb socket 200 upper port are connected with heat dissipation base 300 with screw connecting mode, bulb socket 200 is made by insulating materials, play and stop electric current directly by lamp holder nut 100, to be passed to the effect of heat dissipation base 300, improve the security of product, profile is also more attractive in appearance, generous simultaneously.
Heat dissipation base 300 inside are set to hollow cavity and lateral wall is provided with the contact area that some the first radiating fin 301, the first radiating fins 301 increase heat dissipation base 300 and extraneous air, have greatly accelerated heat radiation express delivery.LED light source assembly comprises being close to and is installed on the circuit board of light source cavity 403 bottoms, is evenly laid in the some LED lamp pearls on circuit board, the drive unit being electrically connected to LED lamp pearl, and drive unit is placed in heat dissipation base 300 hollow cavities.Heat dissipation base 300 inside are set to hollow cavity, and the heat that drive unit produces like this has enough space divergences to go out, heat dishoarding, and rapid heat dissipation, has guaranteed the long-term normal work of LED light source assembly effectively, has extended the service life of LED light source assembly.
It is fixing, into a single integrated structure that heat dissipation base 300 and light source mounting disc 400 are connected by screw, and heat dissipation base 300 makes by heat-conducting metal with light source mounting disc 400, heat-conducting metal aluminium, copper or iron.The heat producing while being close to the LED light source work in light source mounting disc 400, can be delivered to rapidly on each position of heat dissipation base 300 and light source mounting disc 400, rapid heat dissipation, thermal conductivity are good, further guarantee the long-term normal work of LED light source assembly, extended the service life of LED light source assembly.
Especially the light source mounting disc 400 sides circular radiating ring that extends outwardly out, heat dissipating ring is provided with some heat radiation through holes 401, and heat radiation through hole 401 extends some the second radiating fins 402 down.Heat radiation through hole 401 utilizes the cross-ventilated natural law to carry out exchange heat, reaches the object of quick heat radiating.Through hole 401 extended some the second radiating fins 402 down dispel the heat simultaneously, both the area of dissipation having increased widely, the heat producing during effectively by LED chip and drive unit work is dispersed into rapidly in extraneous air, guaranteed the long-term normal work of LED light source assembly, extended the service life of LED light source assembly, also effectively utilized perforate clout, met the theory of low-carbon energy-saving environmental protection, and simple in structure, production cost is low, aesthetic in appearance.The perfect adaptation of heat dissipating ring, heat radiation through hole 401 and the second radiating fin 402, has overcome traditional high-powered LED lamp radiator structure complexity, designs comparatively stiff singlely, and radiating effect is undesirable shortcoming also.
Diffuser 500 is made by glass or plastics, is smooth, smooth-going cambered surface.Light becomes evenly soft after seeing through diffuser 500, and visual effect is splendid, has eliminated light pollution, and illumination effect is good and do not produce dazzle and make people feel dizzy.
