Abstract

The utility model discloses an LED lamp graphite heat conducting and radiating device, which comprises an LED lamp body and an LED light source, wherein the LED light source is mounted at the front surface of a heat radiating substrate, a plurality of strip projections which are formed integratedly are evenly arranged at the back surface of the heat radiating substrate, the back surface of the heat radiating substrate is provided with a groove which is filled with heat conducting and radiating graphite plates, and the external edge of the graphite plate is coated by a bracing frame and fixed on the heat conducting substrate. The heat conducting substrate and the bracing frame are made of aluminium section bar or copper section bar. In the graphite heat conducting device of the utility model which is composed of a graphite plate, a heat radiating section bar and an aluminium bracing frame, the graphite plate is tightly inserted into the groove of the heat radiating substrate, and is fixed on the heat radiating substrate by the aluminium section bracing frame which are tightly coated to form a whole, therefore the graphite heat conducting device can rapidly absorb the heat generated by the LED light source lighting and rapidly radiate by the surfaces of a plurality of groups of graphite plates, thereby effectively reducing the high temperature generated by the LED lamp light source, and ensuring the lamp equipment normal operation and lighting.

Description

A kind of LED lamp graphite heat conducting heat abstractor

Technical field

The utility model belongs to the material technology field, relates to a kind of graphite heat conducting material, is specifically related to a kind of LED lamp graphite heat radiator.

Background technology

In existing electric light source technology, adopt LED lamp very general, of all kinds, the bright and colourful LED lamp that throws light on to increase fine view for people's life.Though the LED lamp is a kind of light that requires of composite energy-saving environment protection,, the LED lamp is lighted simultaneously in energising, can produce higher heat, and heat distributes speed can produce significant effects to the LED lamp life-span.Thereby at present general LED lamp all dispels the heat with heat conducting element.And the metal species heat conducting element that dispels the heat used usually, higher and thermal conductivity factor is lower because of itself density, can not carry out the LED lamp is played the effect of heat conduction cooling effectively, tend to make the LED lamp of operate as normal to burn out, initiating failure, cause some unexpected consequences to people, bring many sorry.

Summary of the invention

The purpose of this utility model is to utilize the superior heat conductivity energy of graphite flake, low thermal resistance, lightweight characteristics, provide a kind of simple in structure, the graphite heat conducting device of radiating and cooling easy to use, as to be suitable for the LED lamp, it is poor to have solved the heat conduction that the LED lamp exists in prior art cooling, burn out the problem of initiating failure easily.

The technical scheme that the utility model adopted is, a kind of LED lamp graphite heat conducting heat abstractor, comprise LED lamp body and led light source, described led light source is installed on the heat-radiating substrate front, in the groove that the integrally formed evenly distributed a plurality of strip projected parts in the heat-radiating substrate back side are provided with, the heat conduction and heat radiation graphite flake is housed, and it is coated and be fixed on the heat-radiating substrate with it to continue to use bracing frame at heat conduction and heat radiation graphite flake outer.

LED lamp graphite heat conducting heat abstractor described in the utility model, its feature also be,

Described heat-radiating substrate and bracing frame are and are aluminium section.

The beneficial effects of the utility model are, owing on the heat-radiating substrate of LED lamp, installed and fixed and had superconduction heat, low thermal resistance, lightweight graphite flake, by graphite flake, graphite flake inserts in the groove of heat-radiating substrate tightly in the graphite heat conducting heat abstractor that heat radiating material and aluminium matter bracing frame are formed, tightly coated aluminium matter bracing frame is fixed on the heat-radiating substrate and becomes one, therefore the heat that can be rapidly led light source be produced when luminous of this graphite heat conducting heat abstractor absorbs rapidly and comes and distribute fast by the surface of many groups graphite flake, reduce the high temperature that the LED lamp source produces timely and effectively, guaranteed normal operation of light units and illumination.

The specific embodiment

Below in conjunction with the drawings and specific embodiments the utility model is elaborated.

A kind of LED lamp graphite heat conducting heat abstractor, as depicted in figs. 1 and 2, comprise LED lamp body 1 and led light source 2, described led light source 2 is installed on heat-radiating substrate 3 fronts, in the groove 5 that the integrally formed evenly distributed a plurality of strip projected parts 4 in heat-radiating substrate 3 back sides are provided with, heat conduction and heat radiation graphite flake 6 is housed, and it is coated and be fixed on the heat-radiating substrate 3 with it to continue to use bracing frame 7 at heat conduction and heat radiation graphite flake 6 outer.

Plant as can be seen from Fig. 2, because graphite flake 6 inserts in the groove 5 of heat-radiating substrate tightly, use aluminium matter bracing frame with its tightly coated again, and be fixed on the heat-radiating substrate 3 and become one, therefore the heat that can be rapidly led light source 2 be produced when luminous of this graphite heat conducting heat abstractor absorbs rapidly and comes and distribute fast by the surface of many groups graphite flake 6, reduce the high temperature that led light source 2 produces timely and effectively, guaranteed normal operation of light units and illumination.

Consider the reliable and more effectively heat radiation that helps the LED lamp fastening, be used for described heat-radiating substrate 3 of the utility model graphite heat conducting heat abstractor and bracing frame 7 and be thermal conductivity preferred metal aluminium section.

Fig. 3 and Fig. 4 are square with the circular LED lamp graphite heat conducting heat abstractor example schematic of the utility model, in addition, can also make the shape of other geometric figure structure.

Several examples that the utility model is above-mentioned; not enforcement and the interest field that is used for limiting utility model; all equivalences of making according to the described content of the utility model patent protection scope change and modify, and all should be included in the utility model claim.
