Abstract
The invention discloses a high-power LED streetlamp cap capable of radiating heat by adopting a water-cooling way, which comprises an LED lamp. Heat radiating fins are arranged on the LED lamp. The high-power LED streetlamp cap capable of radiating heat by adopting the water-cooling way is characterized in that a vacuum water bag is arranged above the heat radiating fins; the bag body of the water bag is made from airtight fireproof fibers; a shield covers the water bag; a plurality of ventilating and heat radiating small hoes are arranged around the shield to form convection for improving the heat radiating effect. As the heat radiation by a heat radiating fin way is combined with the heat radiation by a water-cooling way and the plurality of heat radiating vent holes are arranged in the shield to form the heat energy convection, the quite ideal radiating effect is achieved.
Description
Technical field
The present invention relates to a kind of lighting, relate 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.Chinese patent CN201149184 cross-ventilation radiating high-power LED road lamp and for example.Its objective is and solve the high-power LED lamp heat dissipation problem, a kind of cross-ventilation radiating high-power LED road lamp is proposed, it includes lamp adapter assembly, light fixture radiator assembly and lamp tail assembly, light fixture radiator assembly is an arc post to which the strings of a musical instrument are attached shape housing, both ends open, its arc column face two sides are facade, facade also has array through-hole, arc post to which the strings of a musical instrument are attached shape housing inner chamber be provided with 4～10 axially-aligned and with the affixed stud heat-conducting plate of arc column face chord cylinder, two facades of stud heat-conducting plate arc string cylindrical shell both sides also all have array through-hole, and two facades of stud heat-conducting plate arc string cylindrical shell both sides form the heat dissipation channel that 5～11 hot-airs flow in light fixture radiator assembly.It is desirable that above-mentioned technology former structure complexity, latter's radiating effect are also owed.
Summary of the invention
The present invention solves 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 invention 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.
Technical scheme of the present invention can also be further perfect:
As preferably, on water bag, be coated with protective cover, be provided with a plurality of ventilation and heat apertures around the protective cover, form convection current to improve radiating effect.
As preferably, the protective cover 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.
As preferably, the water in the water-cooled bag is anticorrosion water.
Beneficial effect of the present invention 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 are average about 50 ℃; The temperature of fin of the present invention when the light fixture operate as normal is up between average 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 invention;
Accompanying drawing 2 is vertical views of Fig. 1.
The specific embodiment
Below by embodiment, and in conjunction with the accompanying drawings, technical scheme of the present invention 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.
Embodiment 2:
Ventilation and heat aperture 1 is arranged on around the side of protective cover 4, causes cross-ventilation, improves radiating effect.Other are identical with embodiment 1.
