This shows, the beneficial effects of the utility model are: in the disclosed LED cylinder lamp structure of the utility model, bottom at Lamp cup is provided with radiator, the heat that the LED luminescence unit produces can shed by Lamp cup and radiator simultaneously, increased the area of dissipation of LED Down lamp, the more heat that can shed in the unit interval has improved the radiating efficiency of LED Down lamp, need not to dispel the heat by adding radiator.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment, to do simple introduction to the accompanying drawing of required use among the embodiment below, apparently, accompanying drawing in describing below only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the structural representation of the disclosed LED Down lamp of the utility model embodiment;
Fig. 2 is the structural representation of the disclosed radiator of the utility model embodiment.
The specific embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making under the creative work prerequisite, and the every other embodiment that is obtained belongs to the utility model protection domain.
The utility model discloses a kind of LED Down lamp, itself have radiating efficiency preferably, do not need to dispel the heat by adding radiator.
Referring to Fig. 1 and Fig. 2, Fig. 1 is the structural representation of the disclosed LED Down lamp of the utility model embodiment, and Fig. 2 is the structural representation of the disclosed radiator of the utility model embodiment.
This LED Down lamp comprises: led driver (not shown), Lamp cup 1, substrate 2, LED luminescence unit 3, lampshade 4 and radiator 5.
Wherein, substrate 2 is arranged at the bottom of Lamp cup 1; LED luminescence unit 3 is arranged on the substrate 2, and is connected with led driver; Lampshade 4 is arranged at the top of Lamp cup 1, can cover LED luminescence unit 3 and substrate 2, plays the effect of dustproof and waterproof, and guarantees that the bright dipping of LED Down lamp is even; Radiator 5 comprises main body 51 and fin 52, and main body 51 is arranged on the periphery of Lamp cup 1 bottom, and the shape of its shape and Lamp cup 1 bottom is adaptive, and fin 52 is arranged on the periphery of main body 51.Main body 51 inside at radiator 5 can be provided with a cavity, and led driver is placed wherein, guarantee the aesthetic property of LED Down lamp.
In the LED Down lamp course of work, LED luminescence unit 3 is luminous under the driving of led driver, and produces heat.The heat part that LED luminescence unit 3 produces directly is dispersed on the Lamp cup 1, another part is delivered on the Lamp cup 1 by the substrate 2 that directly contacts with it, because the surface area of Lamp cup 1 is bigger, can play thermolysis, in order to improve the radiating efficiency of LED Down lamp, Lamp cup 1 can be designed to aluminum material,, help heat radiation because aluminium has good thermal conductivity.In addition because Lamp cup 1 is connected with the main body 51 of radiator 5, so the heat on the Lamp cup 1 will be delivered on the main body 51 of radiator 5, main body 51 be arranged on the effect that fin 52 on the main body 51 all can play heat radiation.After radiator 5 is set, increased the area of dissipation of LED Down lamp, help improving the radiating efficiency of LED Down lamp.
