Description

A kind of LED lamp of many side heat radiations

Technical field

The utility model relates to LED lamp field, specially refers to the wandering hot LED lamp of a kind of novel realization side.

Background technology

In the LED field, its heat dissipation problem perplexs numerous research staff always, because the LED working time is long, the space of its lamp body encapsulation is more and more littler, heat dissipation problem will be more outstanding, traditional LED lamp arranges the fin heat radiation in the periphery of Lamp cup, and for the LED lamp, power supply is absolutely necessary, general power supply all is arranged on the lamp holder, and the distance between lamp holder and the led chip is very short, generally all be to separate by a fixed head between it, when the caloric requirement that led chip produces was dispelled the heat by fin, heat will pass through lamp holder, the power supply of lamp holder setting itself produces certain heat owing to work long hours, and adds that the heat of led chip just might make power source life reduce.In addition for the long LED fluorescent tube of some length, for can adopting cross-ventilated mode, the effect that improves its heat radiation dispels the heat, but existing LED lamp adopts general aluminium base to be made into column, and the LED lamp is set in the above, though can reach the effect of heat radiation, but these structures can not be dismantled, can not more talk about, moreover, the LED fluorescent tube that length is long, the flow path of its hot-air convection heat radiation is long also to be unfavorable for dispelling the heat.

The utility model content

The technical problem to be solved in the present invention provides a kind of LED lamp of heat loss through convection, and its good heat dissipation effect is easy for installation, can remove and install, and realizes that the side heat radiation improves radiating efficiency.

Be achieved through the following technical solutions above-mentioned purpose:

A kind of LED lamp of many side heat radiations, comprise lampshade, radiator, LED, pcb board, power supply and Lamp cup, described LED is arranged on the described pcb board, on the described radiator pcb board is set, described LED arranges lampshade outward, and described radiator is connected with Lamp cup by fixed leg, described power supply is arranged in the described Lamp cup, described radiator is column structure, uniform radiating groove on the described radiator lateral surface, and the outer surface of the described relatively radiator of described radiating groove caves inward.

Described lampshade comprises some arc lampshade bars.Described arc lampshade bar both sides arrange bending part, and described bending part is to the inside bending of arc lampshade bar.The part of the radiator between the adjacent radiating groove is symmetrical arranged two openings recess outwardly and two recesses that opening is relative, on the radiator and between the relative recess of two openings groove is being set.Described pcb board both sides are stretched into described two recesses that opening is relative respectively, the fixing described pcb board of the recess that described two openings are relative, the bending part of described lampshade stretches into two described openings recess outwardly respectively, and described arc lampshade bar is fixed on the described radiator.

The beneficial effects of the utility model are: use the radiator with column, this radiator arranges a plurality of radiating grooves, and the heat of pcb board dispels the heat to radiating groove from groove, dispels the heat from side by many radiating grooves, reaches the effect of quick heat radiating, improves radiating efficiency.

The specific embodiment

Below in conjunction with accompanying drawing the present invention is further specified:

The direction term of mentioning in following examples, for example " upper and lower, left and right " only are directions with reference to the accompanying drawings, therefore, the direction term of use is to illustrate not to be to limit the utility model.

As depicted in figs. 1 and 2, a kind of LED lamp of many side heat radiations, comprise lampshade 1, radiator 2, LED3, pcb board 4, power supply 5 and Lamp cup 6, described LED3 is arranged on the described pcb board 4, on the described radiator 2 pcb board 4 is set, described LED3 arranges lampshade 1 outward, described radiator 2 is connected with Lamp cup 6 by fixed leg 7, described power supply 5 is arranged in the described Lamp cup 6, described radiator 2 is column structure, uniform radiating groove 8 on described radiator 2 lateral surfaces, the outer surface of the described relatively radiator 2 of described radiating groove 8 caves inward, radiating groove 8 in this structure can realize air in radiating groove 8 from top to bottom heat radiation can realize that also side flows out the air heat radiation, thereby reach the purpose of quick heat radiating.

Described lampshade 1 comprises some arc lampshade bars.The shape of certain described arc lampshade bar also is not limited to arc; for example Figure 2 shows that wherein a kind of alternate embodiment of lampshade shape; the shape of lampshade can have a plurality of the lampshades that constitute curve shape; should be understood that every pcb board periphery that can coat can be enough realizes that to the LED of the inside the lampshade bar of other shapes of light diffusion function all should fall into protection domain of the present utility model.Described arc lampshade bar both sides arrange bending part 12, and described bending part 12 is to the inside bending of arc lampshade bar.The part of the radiator 2 between the adjacent radiating groove 8 is symmetrical arranged two openings recess 10 outwardly and two recesses 11 that opening is relative, on the radiator 2 and between the relative recess of two openings groove 9 is being set.Described pcb board 4 both sides are stretched into the relative recess 11 of described two openings respectively, the recess 11 fixing described pcb boards 4 that described two openings are relative, the bending part 12 of described lampshade 1 stretches into two described openings recess 10 outwardly respectively, and described arc lampshade bar is fixed on the described radiator 2.Find out that as shown in Figure 1 and Figure 2 its anabolic process is very simple, dismounting also is to make things convenient for very much.
