Description
Technical field
The utility model relates to a kind of LED light fixture, particularly relates to a kind of high-efficiency heat radiating LED lamp.
Background technology
LED (Light Emitting Diode, light emitting diode) is a kind of solid-state semiconductor devices that can be visible ray by electric energy conversion.Because LED can directly be converted into light electricity, LED has very high photoelectric transformation efficiency, therefore LED is more energy-conservation.And because LED is not because there is no filament, be pure semiconductor light-emitting component, it has quite high service life.Be 150 times of ordinary incandescent lamp the service life of LED lamp, is 75 times of fluorescent tube electricity-saving lamp.The service life of general qualified LED lamp is all more than 3～60,000 hours.As the operating current to LED lamp, carry out effectively and control, can reach 8～100,000 hours its service life.And because the inside of LED lamp is without qi of chong channel ascending adversely body, unlike the photophore inside having, rush pernicious gas, do not need the harmful substance composition of excitation electron yet.For example fluorescent tube electricity-saving lamp just must be with the liquid mercury of excitation electron, therefore the relatively environmental protection of LED lamp.In addition, the lamp pearl of LED lamp smaller, be suitable for small space illumination.Therefore, LED lamp is widely used in illuminating industry.
LED light fixture in use can produce a large amount of heat, if heat dissipating not in time can directly have influence on service life and the efficiency of LED particle so.Therefore for to LED heat radiation, be conventionally furnished with in addition radiator in LED light fixture, the body of radiator and LED light fixture is connected or clamping by screw conventionally; Because the body of radiator and LED light fixture is connected or clamping by screw, usually cause the body of radiator and LED light fixture not fit tightly, the heat producing in the LED light fixture course of work, can not transmit a radiator fast.Radiator mainly consists of the rounded thermal column in a plurality of cross sections.In order to improve the radiating effect of LED light fixture, usually need the radiator that dose volume is larger, to increase area of dissipation, cause LED light fixture volume larger, and increased manufacturing cost.
Utility model content
The shortcoming of prior art in view of the above, the purpose of this utility model is to provide a kind of excellent in heat dissipation effect, volume is little and the high-efficiency heat radiating LED lamp of low cost of manufacture.
For achieving the above object and other relevant objects, the utility model provides a kind of high-efficiency heat radiating LED lamp, and described LED light fixture comprises lampshade, radiator, LED module, shadow shield and lens, and described lampshade upper end is connected with described radiator; On described radiator lower surface, order is provided with described LED module, shadow shield and lens, described LED module, shadow shield and lens are all included in described lampshade, described radiator is made by aluminum, and described radiator is closely connected by heat-conducting silicone grease with described LED module; Described radiator comprises pedestal and is located at the many thermal columns in described base top surface, the c-shaped or U-shaped of the cross section of described thermal column; Described pedestal is connected with suspension hook, and described radiator end face is provided with for blocking the decoration top cover of described suspension hook and described pedestal junction, and described decoration top cover is enclosed within described suspension hook lower end.
Further, described thermal column is arranged along the concentric circles contour of many different-diameters.
Further, described pedestal is provided with joint pin, and described decoration top cover is connected with described joint pin by screw.
Further, described shadow shield is all connected with described pedestal by screw with lens.
Further, described decoration top cover is plate-like.
As mentioned above, a kind of high-efficiency heat radiating LED lamp of the present utility model, has following beneficial effect:
Because described radiator is made by aluminum, described radiator is closely connected by heat-conducting silicone grease with described LED module, therefore a large amount of heat energy that produce when described LED module is worked pass to described radiator enough fast, and falls by described heat sink radiates; And because described radiator comprises pedestal and is located at the many thermal columns in described base top surface, c-shaped or the U-shaped of the cross section of described thermal column, this cross section thermal column c-shaped or U-shaped is equivalent to ventilating duct, and itself and air form free convection, heat can be dissipated rapidly; Simultaneously, it is larger that the cross section thermal column thermal column rounded with cross section c-shaped or U-shaped compared area of dissipation, and for same LED light fixture, the radiator of smaller size smaller just can be realized preferably radiating effect, thereby reduced the volume of LED light fixture, and reduced manufacturing cost.
