Description

The efficient LED lighting device

Technical field

The utility model belongs to lighting field, is specifically related to a kind of efficient LED lighting device.

Background technology

The LED lamp is called light emitting diode again, is luminous efficiency height, the long semiconductor light emitting source of life-span of generally acknowledging at present, under rated condition, can reach its service life more than 100,000 hours, so be used widely, after the voltage of LED lamp doubled, its brightness meeting became the increase of several times; But in the prior art, the voltage of every LED lamp is at 3V to 3.2V, electric current is at 20MA, comprise more existing high-power, expensive light emitting diodes, brightness does not all include outstanding, being only limited to closely illumination uses, thereby it is poor in result of use more than 6 meters or on the advertisement Projecting Lamp product, if will increase luminosity by the voltage that increases LED lamp two ends, but the caloric value that can make the LED lamp simultaneously increases and the LED lamp is burnt out, and this shows, in the prior art, the LED lamp has hindered the raising of lamp brightness owing to be subjected to the restriction that hot pressing presses down (bright height promptly generates heat).

Summary of the invention

The purpose of this utility model is to provide a kind of efficient LED lighting device.

The utility model is achieved through the following technical solutions:

A kind of efficient LED lighting device, in housing, be provided with circuit board, the lamp courage of LED lamp is connected on the circuit board by connecting pin, on housing, be provided with import, outlet, being provided with the cooling duct in housing connects import, outlet, lamp courage to small part places in this cooling duct, is provided with blower fan on one of them at least in described import, outlet or cooling duct.

In the utility model, the lamp courage is as main heat generating components, the lamp courage of LED lamp is placed in the cooling duct, the heat that the lamp courage is produced is dispersed in the cooling duct, the lamp courage of LED lamp can be cooled timely, so can more work under the high voltage at the LED lamp, its luminous intensity can become the increase of several times like this, luminous intensity is big, as being 12 to 80W at LED lamp power, when being 12 to 24V, voltage can reach the illuminance of 100 to 400 watts of metal halide lamps, Bao Wenke reaches 2500 to 6500K, is reaching under the equal brightness condition, and its power consumption is than 5 to 10 times of common metal halogen lamp power savings.

Further improvement of the utility model is:

On described housing, be provided with positive and negative two light-emitting areas, be equipped with described LED lamp on each light-emitting area.

Perhaps described LED lamp is at least two rows, and every row is made up of at least three LED lamps.Further, described housing is provided with at least three light-emitting areas, is equipped with the described LED lamp of at least one row on each light-emitting area.

Perhaps described LED lamp is a plurality of LED lamp arrays of forming, and its LED lamp array can be regular polygon (as equilateral triangle, regular hexagon) or circle.

Each described LED lamp serial or parallel connection is provided with.

At least be provided with blower fan on one of them in described import, outlet or cooling duct.Can in the cooling duct, feed cold wind by blower fan, to strengthen the cooling effect of LED lamp.

This lighting device also includes heat dissipation box, and lamp courage to the small part of described LED lamp places in the heat dissipation box, and fills Heat Conduction Material in the slit between heat dissipation box and lamp courage.The heat that LED lamp courage is produced passes to Heat Conduction Material, heat dissipation box successively, is dispersed into heat in the cooling duct by heat dissipation box again or is passed to outside this lighting device, makes the cooling effect of LED lamp better.Wherein, heat dissipation box can adopt metal material to make, and Heat Conduction Material can be selected thermal conductivity good silicone grease glue or refrigerant for use.
