Abstract
The utility model discloses a high-power LED (light-emitting diode) anti-explosion lamp and a heat radiation device thereof. The utility model mainly solves the problem that the existing heat radiation device has a poor heat radiation effect. The high-power LED anti-explosion lamp and the heat radiation device thereof are characterized in that a shell of the lamp is annular, the shell of the lamp is provided with radiating fins, the radiating fins are uniformly distributed on a shell of a lamp base, and a transparent heat radiation cavity is formed between every two adjacent radiating fins. The high-power LED anti-explosion lamp and the heat radiation device thereof have the advantages that natural wind enters the heat radiation cavities so as to accelerate heat radiation; in addition, the superficial area of the radiating fins is large, and the heat radiation effect is better.
Description
Technical field
The utility model relates to a kind of heat abstractor, is specifically related to a kind of heat abstractor of high-power LED explosion-proof lamp.
Background technology
Illumination at explosive gas atmosphere must be used explosion-proof lamp, in order to reach explosion-proof purpose, the inside and outside necessary strict seal isolation of light fixture, the shell that the heat that the electric light source of lamp interior produces in luminous like this can only pass through light fixture is to external radiation, and radiating condition is poor.Current explosion-proof lamp heat abstractor utilizes the thermolysis of having held concurrently of the reinforcement on lamp outer casing more, but light fixture easily gathers amount of heat like this, and the electric light source temperature rise is too high causes shorten service life.
The utility model content
In order to overcome the deficiency of background technology, the utility model provides that a kind of heat exchanger effectiveness is high, simple in structure, the heat abstractor of adaptable high-power LED explosion-proof lamp.
The technical scheme that the utility model adopts: a kind of heat abstractor of high-power LED explosion-proof lamp, comprise lamp outer casing, lamp outer casing is annular, described lamp outer casing is provided with a plurality of fin, described fin is evenly distributed on outer cover of lamp holder, forms the heat radiation chamber of a transmission between two adjacent fin.
The bottom core of described fin is higher than Outboard Sections, and the bottom of described fin is circular shape.
A kind of high-power LED explosion-proof lamp with described heat abstractor, comprise lamp outer casing, LED illumination component, described lamp outer casing is annular, described lamp outer casing bottom is provided with Transparent lamp shade, described LED illumination component is installed in lamp outer casing, described lamp outer casing is provided with a plurality of fin, and described fin is evenly distributed on outer cover of lamp holder, forms the heat radiation chamber of a transmission between two adjacent fin.
The beneficial effects of the utility model are: adopt above scheme, natural wind screws in fin, by the heat radiation chamber, can accelerate heat radiation, and fin surface is long-pending large, and radiating effect is better.
The accompanying drawing explanation
Fig. 1 is the utility model example structure schematic diagram.
The cutaway view that Fig. 2 is the utility model embodiment.
Fig. 3 is the utility model example structure schematic diagram.
1-lamp casing in figure, 2-fin, 21-fin bottom, the 3-chamber of dispelling the heat, 4-Transparent lamp shade, 5-LED illumination component.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model embodiment is described further:
As shown in Figure 1, a kind of heat abstractor of high-power LED explosion-proof lamp, comprise lamp outer casing 1, lamp outer casing 1 is annular, described lamp outer casing 1 is provided with fin 2, and described fin 2 is evenly distributed on outer cover of lamp holder 1, often between two adjacent fin 2, forms the heat radiation chamber 3 of a transmission, when natural wind is blown over, just can accelerate the fin heat radiation by the heat radiation chamber, simultaneously described fin 2 reinforcement on original shell body of comparing, its surface area is larger, dispels the heat faster.
As shown in Figure 2, bottom 21 cores of described fin 2 are higher than Outboard Sections, and this kind of structure is conducive to wind is screwed in to the heat radiation chamber more, accelerates heat radiation, and described fin 2 bottoms are circular shape, the circular shape better effects if.
As Fig. 1, shown in Fig. 2 and Fig. 3, a kind of high-power LED explosion-proof lamp with described heat abstractor, comprise lamp outer casing 1, LED illumination component 5, described lamp outer casing 1 is annular, , described lamp outer casing 1 bottom is provided with Transparent lamp shade 4, described LED illumination component 5 is installed in lamp outer casing 1, described lamp outer casing 1 is provided with a plurality of fin 2, described fin 2 is evenly distributed on outer cover of lamp holder 1, often between two adjacent fin 2, form the heat radiation chamber 3 of a transmission, LED illumination component 5 sees through Transparent lamp shade 4 and outwards throws light on, utilize fin 2 to be dispelled the heat simultaneously, when blowing, natural wind just can be involved in heat radiation chamber 3, thereby accelerate heat radiation, fin 2 quantity are many simultaneously, contact area is large, make radiating rate faster, can effectively control light fixture heats up, increase the service life.
