Description

A kind of LED shot-light

[affiliated technical field]

The utility model relates to a kind of light fixture, refers in particular to a kind of LED shot-light.

[background technology]

At present, LED (Light Emitting Diode) technology is day by day ripe, and begins to come into the appearance of the great power LED product of lighting field, especially 80lm/W at home gradually, and allowing LED replace traditional lighting bulb becomes possibility.

With respect to traditional light source, great power LED is as lighting bulb, it is low-voltage power supply a little, single-chip LED operating voltage is generally at 3～4 volts, far below the operating voltage of common bulb, and safe and reliable, simple in structure, because LED is a solid state light emitter, with respect to traditional osram lamp, have shock-resistant, vibration resistance, be difficult for advantages such as fragmentation, LED is a cold light source in addition, and controllability is good, and response speed is fast, can be repeatedly frequent light on and off and can not damaging, therefore its long service life (more than 50,000 hours) is 4～5 times of conventional light source such as incandescent lamp, avoids frequent maintenance and changes; And the LED high-efficient energy-saving environment friendly, its luminescent spectrum nearly all concentrates on visible light wave range, illuminating effect is more energy-conservation more than 50% than conventional light source, and do not contain harmful element and heavy metal pollution-free.

Now, the light source that mainly uses of LED light fixture is great power LED on the market, the luminous flux of its single great power LED is more than 80lm, can reduce the quantity of led light source, make uniformity relatively easy to control, the reliability height, but great power LED when work caloric value is bigger, if heat is not distributed when anxious, will cause the life-span of LED light fixture to descend, therefore heat dissipation problem is the problem that must solve in the great power LED use, yet the radiator processed complex of great power LED on the market cost an arm and a leg, and the overall structure of LED light fixture is loaded down with trivial details now, thereby caused holding at high price of LED light fixture, be unfavorable for the popularization of LED light fixture.

In order to solve the problems of the technologies described above, the purpose of this utility model be to provide a kind of simple in structure, cost of manufacture is cheap, simple in structure, moulding succinct, good heat dissipation effect, and the effective LED shot-light of bright dipping.

The utility model is that the technical scheme that its technical problem of solution is taked is: a kind of LED shot-light comprises a led light source; One is used to carry the heat-conducting substrate of described led light source; One is connected to the constant current control piece of described heat-conducting substrate; The input and the lamp holder of described constant current control piece are electrically connected;

It is characterized in that: described led light source top is provided with lens, between described heat-conducting substrate and lamp holder, be provided with an aluminium extruded type radiator, described constant current control piece is placed in the aluminium extruded type radiator, one fixedly snap ring described lens are fixed, between described lamp holder and aluminium extruded type radiator, also be provided with a lamp holder connector.

Described heat-conducting substrate is close to by heat conduction colloid and aluminium extruded type radiator upper surface, and fixes by screw, and the tail end of described aluminium extruded type radiator is fixedlyed connected with the lamp holder connector by screw.

Described aluminium extruded type radiator is provided with a plurality of radiating fins, and described a plurality of radiating fins are emitting shape along the axis of aluminium extruded type radiator and arrange.

The top of described a plurality of radiating fins and tail end respectively are provided with a retainer ring, are reserved with the fixed interval (FI) of conducting up and down between the described radiating fin.

The technical solution of the utility model is compared with prior art: because it has adopted Eco-power aluminium extruded type radiator, therefore its cost of manufacture reduces greatly, and all connecting screws all are arranged on lamp interior, so appearance and modeling is attractive in appearance, and the purity of this aluminium extruded type radiator aluminium is up to 99%, effectively ensured better heat radiating effect, the utility model is provided with lens above light source, so its intensity of illumination can rise by straight line, thereby provide a kind of cost of manufacture cheap, simple in structure, moulding is succinct, good heat dissipation effect, and the effective LED shot-light of bright dipping.
