Description

The long-range Projecting Lamp of LED

Technical field

The present invention relates to the long-range Projecting Lamp of a kind of LED, particularly a kind of light path reaches 300 meters long-distance projection lamp, can be applicable to projection illumination and the High-Pole Lamp illumination in station, harbour, mine, goods yard.

Background technology

At present, the kind that the LED lamp replaces conventional lights relates to all trades and professions, because the restriction of luminous intensity distribution technology, never can release the long-range Projecting Lamp of LED that range reaches 300 meters on the market and replace this quasi-tradition Projecting Lamp, and the application of long-range Projecting Lamp in industrial production and communications and transportation is very extensive, therefore, the long-range Projecting Lamp of design LED is very necessarily.

What be most widely used in the long-range Projecting Lamp of tradition is the 400w high-pressure mercury lamp, compares with the present invention as example, and the radiation response behind the long-range Projecting Lamp light projector of LED reaches on the basis of conventional lights effect, can realize that power saving rate is more than 70%; Improve service life more than 3 times, colour rendering index improves more than 10%, and the colour temperature of light can adjust arbitrarily according to demand, and the weight of lamp also can alleviate half, and these advantages will impel the long-range Projecting Lamp of LED to obtain widely promotion and application.

In sum, also do not have in the market the long-range Projecting Lamp of LED of light path to 300 meter, the present invention will fill up this blank, and be the higher technical scheme of a cost performance.

Summary of the invention

The purpose of this invention is to provide the long-range Projecting Lamp of a kind of LED, adopted a light-output device to realize projecting light onto remote purpose, design has used pyromagnetic new material to be used for heat radiation as lamp body, has realized half purpose of lamp weight saving.

The objective of the invention is to be achieved through the following technical solutions:

The long-range Projecting Lamp of a kind of LED, described Projecting Lamp is comprised of many groups LED light projector device, every group of light projector device comprises led light source and light-output device, described light-output device is positioned at the front end of led light source, comprise taper light conducting cylinder and the little convex lens that are positioned at the light conducting cylinder two ends and large convex lens, described little convex lens are near led light source.

Light conducting cylinder is furnished with the light conducting cylinder sheath outward, and little convex lens and large convex lens all are installed on the two ends of described light conducting cylinder sheath by support and trim ring.

Described led light source is connected with radiator by heat conductive pad.

Described many group LED light projector devices are installed in the housing, are provided with light shield at the hull outside front end.

Described heat conductive pad is the graphite heat conducting pad.

Described housing comprises cover, end cap, bonnet and power storehouse, and described cover, end cap, bonnet form and hold cavity; Described power storehouse is positioned at the back side of housing.

Described housing bonnet adopts thermal-magnetizing material to make, and doubles as the radiator of described led light source.

Described LED light projector device is two groups, and its emergent light has respectively two illumination centers that distance is different.

Also comprise the light fixture fixed mount, connect with the lamp body shell, in order to install and adjusting angle.

The long-range Projecting Lamp of LED of the present invention adopts many group light projector devices, every group of light projector device has far and near different light projector center, every group of light projector device gathers on the gonglion of large convex lens to greatest extent by little convex lens and light conducting cylinder, then light is all throwed away, realize the long-range projection of light.Although two groups of its structures of light-output device of long-range Projecting Lamp are identical, but the lens thickness that uses is not identical, this is that the hot spot that utilizes the principle of the focal length of lens that projection is gone out produces former and later two far and near different illumination centers, allow the photographed object surface form far and near different long strip type hot spot, by that analogy, more how far can produce as required nearly different hot spot, a plurality of different hot spots connect together and can form the optical channel of a strip, in order to satisfy various actual needs.
