Traditional Fog-proof light uses tengsten lamp or fluorescent lamp, and not only luminous efficiency is low, and energy consumption is high, and the thing followed is that its caloric value is high, and life of product is short, needs frequent maintain and replace bulb.LED is as a kind of novel energy-conserving light source, because of advantages such as its high light efficiency, long-life, heat radiation are low obtain application more and more widely, also produces as the Fog-proof light of light source with LED thereupon.The working environment of LED Fog-proof light and use occasion often require light fixture to be in the middle of the environment of sealing, and normally on the light fixture glass outer cover are set, and protective cover is set on the outer cover, cause the inefficacy of light fixture to avoid after slight impact glass to be unlikely to break.Although the traditional relatively Fog-proof light of heat that produces during LED work greatly reduces; But because the restriction of working environment; When adopting great power LED, Fog-proof light is efficiently radiates heat how, also is the important technological problems that faces in the prior art thereby improve the product efficiency, increase the service life.

There is following problem in existing LED Fog-proof light on heat dissipation design:

1, spends radial mode to the outgrowth fin with 360; Because LED thermal source and aluminum metal fins conducting path are far away, a large amount of thermals source can't effectively be done cold cycling exchange rapidly with thermal source and normal temperature by path fin far away; Cause the LED temperature too high, the too fast lifetime of LED light decay.2, the radiating fin of positive effect is far used more greatly and do not have to heat dissipation path, causes the excessive preponderance of small product size.

Summary of the invention

The technical problem that the utility model will solve provides a kind of LED Fog-proof light, and this Fog-proof light can significantly improve the radiating effect of great power LED, prolongs the service life of Fog-proof light.

For solving above technical problem, the utility model adopts following technical scheme:

The LED Fog-proof light comprises cloche, is arranged at the led light source in the said cloche; And be arranged at the outer metal coating mask of cloche; The stiff end of said led light source also is connected with radiator, and one section of said radiator is arranged in the cloche, and another section is arranged at outside the cloche.

Preferred scheme, said radiator are arranged at outer one section of cloche and disperse vertically and be some radiating fins; The heat radiation air flue that connects about forming between the said radiating fin; Said radiating fin is the radiated rib of fin shape.

Scheme further, the quantity of said radiating fin are at least 6; The diameter that said radiator is arranged at interior one section of cloche is to be arranged at 1/2nd of the outer one section diameter of cloche.

Advantage and characteristics that the utility model technical scheme is main are following:

1, the radiating fin that adopts left and right sides uniformity direction to arrange has formed the heat radiation air flue between the radiating fin, the conducting path between radiating fin and LED thermal source shortens, and area of dissipation strengthens, and helps the LED heat radiation, delays the LED light decay, improves service life.2, the compact conformation of radiating fin effectively alleviates the weight of Fog-proof light.

Description of drawings

Fig. 2 is the half sectional view of the utility model LED Fog-proof light;

Fig. 3 illustrates the full sectional view of the utility model LED Fog-proof light.

The specific embodiment

The cardinal principle of the utility model technical scheme is as shown in Figure 1:

The heat that the Fog-proof light internal LED light source is produced is transmitted to the external world via aluminum heat dissipation metal body.The part that radiator is positioned at the Fog-proof light outside is the radiating fin of dispersing, and the part that radiator is connected with led light source is the cylinder of rule.The heat that led light source produces is evenly after the conduction, does heat exchange by exposing at the radiating fin part of several outside high surface areas of Fog-proof light and normal temperature air on every side, reaches heat sinking function.Because of radiating fin is that left and right sides uniformity direction is arranged, promptly radiating fin exposed part symmetric arrangement has formed the air flue that dispels the heat between the radiating fin.When wind direction is a left and right directions when blowing over aluminum heat dissipation metal fin, the thermal source that great power LED produced, the wind band of the aluminum heat dissipation metal fin that will be flowed rapidly leaves around the fin, making heat radiation reach best efficiency.

The half sectional view of the utility model LED Fog-proof light as shown in Figure 2, radiator are positioned at the inner part of Fog-proof light and are cylinder, and the led light source heat of its absorption conducts to the external world via radiating fin.Owing to formed the air flue of heat radiation between the radiating fin, so its area of dissipation is very big.When no any wind, the thermal source air around the radiating fin moves up and leaves around the fin, and cold air gets into the aluminum metal fins by lower and replenishes, and forms the cooling mechanism of the cold cycling of nature.

Shown in Fig. 2 and 3, the outermost of the utility model LED Fog-proof light is provided with aluminum protection mask 4, the damage of breaking of cloche 3 that this protection mask 4 can be avoided being caused after the slight impact of LED Fog-proof light and led light source 2.

Described cloche 3 is arranged at said protection mask 4 inboards, and said led light source 2 is arranged at the inboard of said cloche 3.Said cloche 3 is rotary bodies that an end has opening; It among the embodiment shown in Fig. 2 and 3 rotary body of U-shaped cross-section; Can be spheroid, cylinder etc. also, said cloche 3 be enclosed in the part of led light source 2 and radiating fin 1 in the airtight cavity.

One section of said led light source 2 and radiator 1 is connected.One section of being connected with said led light source 2 of said radiator 1, this part are the cylinder of rule.One section outside that is arranged on protection mask 4 of said radiator 1 is provided with the multi-disc radiating fin, and rule of thumb, said radiating fin is at least 6 could realize better radiating effect.Said radiating fin adopts left and right sides uniformity direction to arrange, and promptly above-mentioned radiating fin is along the cross section symmetric arrangement of LED Fog-proof light, and is connected with LED Fog-proof light stiff end.Form between the said radiating fin and can let the heat radiation air flue of air left and right sides runner.The cylinder diameter that said radiator 1 is positioned at cloche is not less than 1/2nd of cloche diameter

When no any air-flow, the part that radiator 1 is connected with led light source 2 absorbs led light source 2 and ambient heat thereof, and partly conducts to the radiating fin that exposes in protection mask 4 outsides.Expose the radiating fin part in protection mask 4 outsides, owing to adopt left and right sides uniformity direction to arrange, promptly radiating fin exposed part symmetric arrangement forms the heat radiation air flue, and has bigger area of dissipation, therefore, has better radiating effect.Because the radiating rate of radiating fin is faster, has produced heat bridge effect between inside and outside two parts of radiator, form the cooling mechanism of the cold cycling of nature.

As shown in Figure 3, the radiating fin of the utility model Fog-proof light is the radiated rib of type of being assembling manch shape, and its area of dissipation is big, and volume is little, helps to improve radiating efficiency and alleviates light fixture weight.

Need to prove at last; The above is merely the preferred embodiment of the utility model; Rather than, anyly be equal to replacement or corresponding improvement to what the utility model technical characterictic did to the qualification of the utility model technical scheme, still within the protection domain of the utility model.
