Description

Heat radiator for LED lamp

Technical field

The utility model is related to LED lamp, and in particular to a kind of heat radiator for LED lamp.

Background technology

Have that small volume, power saving, reaction time be fast, color by LED (Light Emitting Diode, light-emittingdiode) The advantageous characteristics such as abundant and environmental protection, already as important light-emitting component indispensable in the modern life.Its also generally conduct Lamp lighting is used, and forms a LED lamp.

LED can produce heat and high temperature, when it often raises 1 DEG C, the LED when illumination uses and is converted into luminous energy by electric energy Brightness will decline 0.9%.Influence of the temperature-rise effect to LED luminance as can be seen here has more important.So how effectively to dissipate Heat becomes the important problems of the LED to keep the brightness of the LED.

LED be used to illuminate and as illuminator in use, being usually to set and dissipated with multiple in the lampholder shell of LED lamp Hot fin, to be used as radiating.However, during using radiating fin as sinking path, it only has the radiating effect of heat transfer, And the radiating effect without free convection, and because radiating fin is excessively intensive, some heat temperature can also lodge in each heat radiating fin Between piece, thus its radiating effect is not kindhearted.

Utility model content

In view of the shortcomings of the prior art, the purpose of this utility model aims to provide the LED of good heat dissipation effect a kind of with dissipating Hot device

To achieve the above object, the utility model is adopted the following technical scheme that：

Heat radiator for LED lamp, it is made by Heat Conduction Material, including

Heavy remaining power supply mounting hole is provided with the middle part of the bottom plate of toroidal, surface thereof, in the outer of heavy remaining power supply mounting hole Enclose and circumferentially spaced about be evenly distributed with heat emission hole；

Fin, its interval is evenly distributed on another surface of bottom plate, is formed between two adjacent, parallel fin Transversal ventilation groove；Fin is distributed four fin groups of formation, respectively the first fin group, the second radiating on bottom plate Piece group, the 3rd fin group and the 4th fin group, wherein, the first fin group and the 4th fin group with A diameter of symmetry axis of bottom plate is symmetrically disposed in the circumferential edge of bottom plate, and the second fin group and the 3rd fin group set It is placed between the first fin group and the 4th fin group, longitudinal ventilation groove is formed between two adjacent fin groups, Transversal ventilation groove in adjacent two fin group is relative and sets；If in the second fin group and the 3rd fin group Screw mounting groove is formed with dry fin.

Lamp installation frame is provided with the circumferential edge of the bottom plate.

The radiator is drawn by fine aluminium and is molded.

The width of the transversal ventilation groove is 3-8mm, and the width of the longitudinal ventilation groove is 2-6mm.

The beneficial effects of the utility model are：

The utility model heat radiator for LED lamp has two kinds of radiating modes, conduction and convection current simultaneously, leads to than existing frequently-used Crossing the radiating mode of single conduction has more preferable radiating effect, so that the service life of product is significantly carried It is high.

Embodiment

Below, with reference to accompanying drawing and embodiment, the utility model is described further：

As Figure 1-4, heat radiator for LED lamp of the present utility model, it is made by Heat Conduction Material, including toroidal Bottom plate 2, heavy remaining power supply mounting hole 20 is provided with the middle part of surface thereof, in this way, heavy remaining power supply can be provided with bottom plate, To ensure the work of LED, interval is evenly distributed with heat emission hole 21 in the peripheral circumferential of heavy remaining power supply mounting hole；

Fin 1, its interval is evenly distributed on another surface of bottom plate 2, shape between two adjacent, parallel fin 1 Ventilation slot 10 is open into, in this way, in this way, LED heat produced when working can be by the fin on the back side of bottom plate 2 1 distributes, meanwhile, heat is dispersed into air by the transversal ventilation groove 10 on bottom plate 2 and the backflow of heat emission hole 21, is formed Convection current with surrounding air is conducted, and also can distribute heat in time in the case of no natural wind, that is to say, that this dissipates Hot device has two kinds of radiating modes simultaneously：Conduction and convection current, have more than the existing frequently-used radiating mode by single conduction Good radiating effect, so that the service life of product is greatly enhanced.

Further, fin 1 is distributed four fin groups of formation, respectively the first fin group on a base plate 2 100th, the second fin group 200, the 3rd fin group 300 and the 4th fin group 400, wherein, the first fin Fin group 400 of group 100 and the 4th is symmetrically disposed in the circumferential edge of bottom plate 2 with a diameter of symmetry axis of bottom plate 2, the Two fin groups 200 and the 3rd fin group 300 are arranged at the first fin group 100 and the 4th fin group 400 Between, the transversal ventilation groove 10 formed between two adjacent fin groups in longitudinal ventilation groove 30, adjacent two fin group It is relative and set, in this way, ventilation slot can " ten " shape be interspersed, compared with traditional " one " shape, greatly improve air Flowing velocity, is conducive to the quick of heat to disperse；In some of the second fin group 200 and the 3rd fin group 300 Screw mounting groove 11 is formed with fin 1, in this way, whole radiator can be installed by screw mounting groove 11, in order to Installation and maintenance.

Wherein, lamp installation frame 3 is provided with the circumferential edge of above-mentioned bottom plate 2, as shown in figure 5, passing through lamp installation frame 3 The installation of lampshade 4 can be greatly facilitated so that whole light fixture is more aesthetically pleasing, it is even more important that can effectively prevent rainwater Into with the service life for ensureing security and extending light fixture.

Further, above-mentioned radiator is drawn by fine aluminium and is molded, and the thermal conductivity of aluminium is 237W/ (m.k), and proportion is 2.7g/cm 3, than conventional radiator cast aluminium light specific gravity, thermal conduction effect is more preferable.

Further, since the width of ventilation slot is to influence one of key factor of radiator heat-dissipation performance, if ventilation slot Width is excessive, then shows that the distance between fin 1 is also just excessive, the quantity of fin 1 of distribution on a base plate 2 will subtract It is small, then it is unfavorable for the conduction of heat, if however, the quantity of fin 1 is excessively intensive, although be conducive to the conduction of heat, but The distance that may result between ventilation slot groove is too small, is unfavorable for dispersing for heat, and in order to solve this technical barrier, inventor is through excessive Quantifier elimination finds, when the width of transversal ventilation groove 10 is 3-8mm, when the width of longitudinal ventilation groove 30 is 2-6mm, this radiator Not only there is good heat conductive energy, and rapidly can disperse heat, specific in the present embodiment, transversal ventilation The width of groove 10 is 5mm, and the width of longitudinal ventilation groove 30 is 3mm.

It will be apparent to those skilled in the art that technical scheme that can be as described above and design, make other various It is corresponding to change and deformation, and all these change and deformation should all belong to the protection of the utility model claim Within the scope of.
