Abstract
The utility model discloses a high-power LED street lamp cap adopting water-cooling heat dissipation, which is provided with a LED lamp, wherein a radiating fin is arranged on the LED lamp; and the high-power LED street lamp cap is characterized in that a vacuum water bag is arranged above the radiating fin, the bag body of the water bag adopts the airtight fire-proof fiber, a protective cover covers the water bag, and the periphery of the protective cover is provided with a plurality of ventilating heat dissipation holes which form convection current so as to increase the heat dissipation effect. As the heat dissipation of the radiating fin and the water-cooling heat dissipation are combined in the high-power LED street lamp cap and the protective cover is provided with the plurality of ventilating head dissipation holes which form heat convection current, the perfect heat dissipation effect is achieved.
Description
Technical field
The utility model relates to a kind of lighting, relates in particular to a kind of high-power LED street lamp cap.
Background technology
Light emitting diode is with its low energy consumption, high light efficiency, long-life and in the industry the extensive concern of being subjected to throwing light on.Because LED need be could reliably working below 80 ℃, but during great power LED work its moment caloric value very big.If it is not smooth to dispel the heat, will cause a series of problems such as emission wavelength drift, light extraction efficiency decline, fluorescent material accelerated ageing and shortening in service life.The general employing of the heat radiation of LED street lamp cap solves technology such as chip epitaxial structure optimal design, use surface coarsening, use pottery, composite metal substrate and fin on the market, but above technology is unsatisfactory to the effect of single great power LED (more than the 10W).Therefore, how to solve the research focus that the great power LED cooling problem has become lighting field.Be with external radiator high-power LED street lamp fixture as one kind of Chinese patent application CN101201154, comprise light fitting main casing, lampshade, the LED lamp, external radiator, power circuit system, comprise housing (1) on its light fitting main casing, heat pipe connector (2), LED lamp socket (3), heat pipe (8), radiating component (6) constitutes, one end of its light fitting main casing is provided with heat pipe connector (2), one end of heat pipe connector (2) is provided with and is no less than one or one group of heat pipe and is connected in LED lamp socket (3), and the other end of heat pipe connector (2) is provided with and is no less than one or one group of heat pipe and is connected in external radiator.Its external radiator constitutes by being no less than the combination of two unit member couplings.Above-mentioned technical pattern complexity, production cost is higher.
Summary of the invention
The utility model mainly is to solve the existing in prior technology deficiency, thereby develops a kind of simple in structurely, and radiating effect is good, adopts the water cooling high-power LED street lamp cap that combines with the wind-cooling heat dissipating sheet.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of high-power LED street lamp cap that adopts water-cooling, has the LED lamp, on the LED lamp, fin is arranged, it is characterized in that: vacuum water bag (or claiming the water-cooled bag) is installed above fin; The bag of described water bag adopts air-locked fire proofing firbre, and the water in the water-cooled bag is anticorrosion water; On water bag, be coated with protective cover.
The technical solution of the utility model can also be further perfect:
As preferably, around the protective cover or side is provided with a plurality of ventilation and heat apertures, forms convection current to improve radiating effect.
As preferably, protective cover is an arc surface.
The utility model beneficial effect is: because the fin heat radiation is combined with water-cooling, and on protective cover, be provided with a plurality of heat dissipation ventilations hole, and make it to form the heat convection current, reached very good radiating effect:
1, the reasonable fin of prior art, the temperature when the light fixture operate as normal is on average about 50 ℃; The temperature of fin of the present utility model when the light fixture operate as normal is up on average between 30-33 ℃.
2, radiating effect has improved more than 30% than general LED street lamp cap, has solved the heat dissipation problem of high-power LED street lamp cap substantially.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the present utility model;
Accompanying drawing 2 is vertical views of Fig. 1.
The specific embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is further described in detail.
Embodiment 1:
The high-power LED street lamp cap of employing water-cooling as shown in Figure 1, 2, has the LED lamp, fin 2 is arranged on the LED lamp, the hermetically sealed vacuum-packed water bag 3 that adopts fire proofing firbre to make is installed above fin, and the water in the vacuum water bag is anticorrosion water, is coated with protective cover 4 above the water bag, protective cover is an arc surface, around protective cover 4, be provided with a plurality of ventilation and heat apertures 1, cause cross-ventilation, improve radiating effect.
Claims (3)
1. a high-power LED street lamp cap that adopts water-cooling has the LED lamp, and fin (2) is arranged on the LED lamp, it is characterized in that: fin (2) top is equipped with vacuum water bag (3); The bag of described vacuum water bag adopts air-locked fire proofing firbre; On vacuum water bag (3), be coated with protective cover (4).
2. the high-power LED street lamp cap of employing water-cooling according to claim 1 is characterized in that: protective cover (4) has a plurality of ventilation and heat apertures (1) all around.
3. the high-power LED street lamp cap of employing water-cooling according to claim 1 and 2 is characterized in that: protective cover (4) is an arc surface.
