Abstract

The utility model discloses an integrated direct-conduction radiating type LED lamp, which comprises a heat conducting substrate (5) and a transparent body (3) fixed inside a casing (13) hermetically, LED lamp bulbs (4) mounted on the heat conducting substrate and end covers (1) fixedly and hermetically connected with two ends of the casing. A light source area (16) is formed among the heat conducting substrate, the transparent body and the casing; a radiating area (17) is arranged below the heat conducting substrate; at least one layer of folded integrated radiating fins (6) are arranged in the radiating area; and fin holes (12) are arranged on the integrated radiating fins. As the integrated radiating fins are in direct contact with the heat conducting substrate on the LED lamp, heat in the heat conducting substrate can be quickly and directly transferred to the integrated radiating fins and is dissipated to the outside through the radiating area or the casing and ventilating and radiating holes on the casing. Therefore, heat radiating speed is increased, service life of the LED lamp is prolonged, and the size and the wall thickness of the casing are reduced. In addition, the casing of the lamp can be made of nonmetal, thereby saving precious metal, reducing production cost of the casing and the cost of the LED lamp and being favorable for the popularization of the LED lamp.

Description

The integrated radiating type LED lamp of directly leading

Technical field

The utility model relates to the LED lamp, especially relates to a kind of not only simple in structure, low cost of manufacture, and use reliable and stable, the integrated radiating type LED lamp of directly leading that effect is good again.

Background technology

Along with rapid economic development and people's living standard improve constantly, power consumption increases sharply rapidly and with more and more nervous.As everyone knows, compare with existing incandescent lamp, fluorescent lamp, the LED light fixture has the luminous intensity height, the long and few advantage of power consumption of life-span, and the LED lamp has been widely used as illuminating lamp, Landscape Lamp, advertising lamp, wall lamp and Ceiling light etc., its both applicable real electricity, therefore also applicable solar energy and wind power generation are popularized in an all-round way and are used the LED lamp, both had result of use and improved, again the advantage of saves energy in a large number.But in use also there are a heat dissipation problem in existing LED lamp, particularly high-powered LED lamp: it is just high more to increase its caloric value with LED lamp power, if radiating condition is bad, causes LED light to decline easily and burns out.For the LED lamp can fully be dispelled the heat, a heat abstractor just must be set.The LED heat sink for lamp dispels the heat by the case surface of lamp entirely at present, this radiating mode has following point: the one, when LED lamp caloric value increases, housing must enlarge, otherwise the housing heat radiation causes LED light to decline inadequately and burns out, the 2nd, housing must be confined to metal material housings such as the good aluminium of heat conduction, copper, no matter be that housing enlarges or employing precious metal material is made housing, all improved LED lamp manufacturing cost, be unfavorable for promoting the popularization use of LED lamp.

The utility model content

There is the manufacturing cost height at LED lamp in the above-mentioned prior art, be unfavorable for the problem that the LED lamp is extensively popularized, the utility model provides a kind of not only good heat dissipation effect, and it is simple in structure, in light weight, volume is little, the integrated radiating type LED lamp of directly leading that can save precious metal and reduce manufacturing cost, help promoting the popularization use.

The technical scheme that the technical problems to be solved in the utility model is taked is: described integrated directly lead radiating type LED lamp comprise heat-conducting substrate and the transparent body of sealing and fixing in housing, be arranged on the heat-conducting substrate LED lamp pearl and with the sealed at both ends end cap that is fixedly linked of housing, form light source region between the heat-conducting substrate and the transparent body and the housing, heat-conducting substrate is following to be radiating area, is provided with the integrated radiating fin that one deck at least unfolds in radiating area.

According to the environment difference that the LED lamp uses, described LED light source region also can not be provided with waterproof sealing.

In order to improve the heat-conducting substrate and the transparent body sealing property in housing, the housings support projection that is used for fixing the transparent body is provided with seal groove, be provided with encapsulants such as glass cement in the seal groove, be provided with sealing gasket at end cap and the transparent body and heat-conducting substrate joint, to satisfy LED lamp seal request.

Integrated radiating fin is a sheet metal, and thickness 0.3 millimeter preferably adopts aluminium pool, copper pool to make, and for improving integrated radiating fin thermal diffusivity, is processed with the fin fenestra of strip window formula on integrated radiating fin.

The utility model radiating area is that heat-conducting substrate direct by integrated radiating fin and on the LED lamp contacts, thereby can directly the heat on the heat-conducting substrate be delivered on the integrated radiating fin fast, utilize hot-air nature rising principle, heat can directly dispel the heat to the external world to external world's heat radiation or by the ventilating heat dissipating hole on shell and the shell by radiating area, accelerated radiating rate, enlarge heat dissipation capacity, improved LED lamp service life.Integrated radiating fin is identical with the housing volume down, the area of dissipation that integrated radiating fin area contacts with air is more much bigger than the area of dissipation that housing area contacts with air, therefore integrated radiating fin heat radiation is better than the procapsid heat radiation, thereby can dwindle the housing volume, reduce the housing wall thickness, also nonmetallic materials manufacturing such as available plastics of housing, can save the precious metal material, reduce the housing manufacturing cost, reduce LED lamp manufacturing cost, help the LED lamp and extensively popularize.
