Abstract

The utility model discloses an LED lamp with the good heat radiating effect. The LED lamp comprises a hollow lamp main body, wherein a round cup-shaped radiator is arranged at the tail portion of the lamp main body, an LED light-emitting body used for giving out light is arranged at the bottom of the inner wall of the radiator, a solid heat conducting column is arranged in the middle of the outer wall of the bottom of the radiator, a plurality of radiating fins connected with the outer peripheral wall of the radiator are evenly arranged on the outer peripheral wall of the heat conducting column, and the sections of the radiating fins are in arc shapes. The solid heat conducting column is arranged in the middle of the outer wall of the bottom of the radiator, so that heat generated by the LED light-emitting body in work can be quickly transmitted to the radiating fins through the heat conducting column and then exchanges energy with the air efficiently through the radiating fins. Thus, the LED lamp is good in heat radiating effect.

Description

A kind of LED lamp of good heat dissipation effect

Technical field

The utility model relates to a kind of LED lamp of good heat dissipation effect.

Background technology

Along with social development and scientific and technical progress; people more and more focus on saving the energy and protection of the environment; there are the advantages such as energy consumption is low, long service life due to LED light fixture and are more and more subject to people's favor; but LED lamp in the course of the work; heating is large; easily cause it to damage, therefore people need to solve the large problem of LED lamp caloric value.

Utility model content

In order to address the above problem, it is a kind of simple in structure that the purpose of this utility model is to provide, the LED lamp of good heat dissipation effect simultaneously.

The utility model is that the technical scheme that its technical problem of solution adopts is:

A kind of LED lamp of good heat dissipation effect, comprise the lamp main body of hollow, the afterbody of this lamp main body is provided with the radiator of a rounded cup-shaped, the inwall bottom of radiator is provided with for luminous LED illuminator, the bottom outer wall middle of described radiator is provided with a solid heating column, on the periphery wall of this heating column, be evenly provided with the some radiating fins that are connected with radiator periphery wall, the cross section of described radiating fin is circular arc.

As the improvement of technique scheme, the gradient of described radiating fin peripheral region is 1-10 degree.

As the further improvement of technique scheme, the periphery wall of described radiator between adjacent two radiating fins is arc surface.

Further, the bottom of described radiator is provided with a through hole of making way for electric lead.

Further again, on the periphery wall of described lamp main body, be symmetrically arranged with two buckles.

Further, in the inner chamber of described radiator, be provided with a reflector that is looped around described LED illuminator periphery.

The beneficial effects of the utility model are: because the utility model arranges a solid heating column by the bottom outer wall middle at radiator, the heat producing when LED illuminator can be worked by this heating column is promptly delivered to radiating fin place, and then carry out efficient exchange heat by radiating fin and air, thereby make LED lamp good heat dissipation effect of the present utility model, simultaneously because the cross section of radiating fin is circular arc, in the case of not changing the diameter dimension of radiator, increase the contact area of radiating fin and air, strengthen the heat-sinking capability of radiator, thereby make the radiating effect of LED lamp of the present utility model can be better, the periphery wall of described radiator between adjacent two radiating fins is arc surface in addition, therefore after the air between adjacent two radiating fins is heated, can be more easily toward rising along this arc surface, accelerate the Air Flow between adjacent two radiating fins, further promote the heat-sinking capability of radiator, ensured that LED of the present utility model has good radiating effect.

Detailed description of the invention

Referring to figs. 1 through Fig. 3, a kind of LED lamp of good heat dissipation effect, comprise the lamp main body 1 of hollow, the afterbody of this lamp main body 1 is provided with the radiator 2 of a rounded cup-shaped, in order to ensure the heat-sinking capability of radiator 2, in the utility model, the preferential environment-friendly highly efficient heat conduction aluminum alloy that adopts of described radiator 2 is manufactured, further, the bottom wall thickness of this radiator 2 is 8-16 centimetre, the inwall bottom of described radiator 2 is provided with for luminous LED illuminator 3, the bottom outer wall middle of described radiator 2 is provided with a solid heating column 20, preferably, the diameter of described heating column 20 is 15-32 centimetre, on the periphery wall of this heating column 20, be evenly provided with the some radiating fins 21 that are connected with radiator 2 periphery walls, the cross section of described radiating fin 21 is circular arc, because the utility model arranges a solid heating column 20 by the bottom outer wall middle at radiator 2, the heat producing when LED illuminator 3 can be worked by this heating column 20 is promptly delivered to radiating fin 21 places, and then carry out efficient exchange heat by radiating fin 21 and air, thereby make LED lamp good heat dissipation effect of the present utility model, simultaneously because the cross section of radiating fin 21 is circular arc, in the case of not changing the diameter dimension of radiator 2, increase the contact area of radiating fin 21 with air, strengthen the heat-sinking capability of radiator 2, thereby make the radiating effect of LED lamp of the present utility model can be better.

Further, in order to make the manufacture of radiator 2 simpler, enterprise can adopt the mode of casting to produce radiator 2, the gradient of described radiating fin 21 peripheral regions is 1-10 degree, because the gradient of radiating fin 21 peripheral regions is 1-10 degree, therefore enterprise adopts the mode of casting to produce after radiator 2, can facilitate its molding, thereby makes the manufacture of radiator 2 more simple and convenient quick.

Further again, in order to make to accelerate the Air Flow between adjacent two radiating fins 21, the heat-sinking capability of heat radiation device 2, the periphery wall of described radiator 2 between adjacent two radiating fins 21 is arc surface.

Further, in order to make the wiring of LED lamp of the present utility model convenient, the bottom of described radiator 2 is provided with a through hole 22 of making way for electric lead, therefore the electric lead being connected with LED illuminator 3 can pass from the through hole of radiator 2 22, avoids electric lead pass and affect attractive in appearance from the front portion of LED lamp.

Further again, be fixedly mounted on other objects for the ease of LED lamp of the present utility model, on the periphery wall of described lamp main body 1, be symmetrically arranged with two buckles 10.

Further, in order to ensure that LED light fixture of the present utility model has reasonable illuminating effect, in the inner chamber of described radiator 2, be provided with a reflector 4 that is looped around described LED illuminator 3 peripheries, the light reflection that LED illuminator 3 can be sent by reflector lamp 4 concentrates on the position of required illumination, thereby makes the illuminating effect of LED lamp of the present utility model better.

The foregoing is only preferential embodiment of the present utility model, as long as within the technical scheme that realizes the utility model object with basic identical means all belongs to protection domain of the present utility model.
