Technical scheme of the present invention is following:

A kind of photomask that is applicable to the LED light fixture; It comprises photomask, LED light emitting source, lamp housing and fin; Wherein the LED light emitting source is evenly distributed on the upper surface of lamp housing, and photomask is located at the top of LED light emitting source and is connected with the upper surface of lamp housing, and fin is evenly distributed on the lower surface of lamp housing.

Further, the top of described lamp housing also is provided with translucent cover, and translucent cover is connected with lamp housing.

Further, described lamp housing is the plane.

Further, described lamp housing is a circular arc.

Further, described lamp housing is made up of prismatic surface, and the angle between adjacent two prismatic surfaces is greater than 90 degree.

Further, the number of described prismatic surface is at least 3.

Further, the gap between the described fin is 10～25mm, and the height of fin is 30～70mm.

Further, described photomask is a hollow cone platform shape, and the height of photomask is 20～50mm, and back cut diameter is 20～50mm, and lower port diameter is 8～20mm.

Further, the inner surface of described photomask is provided with reflex block, and reflex block is radial evenly distributed along the photomask generatrix direction.

Further, the number of described reflex block is 300～900.

Compared with prior art, the invention has the beneficial effects as follows, owing to adopted photomask and be provided with reflex block at the photomask inner surface; The light source of LED light fixture is reflexed to more than 95% on the object that needs illumination, improved the luminous efficiency of LED light fixture, owing to adopted translucent cover; Can the better protection photomask, avoid the erosion of dust and steam, owing to adopted fin; The heat that can better the LED light fixture be produced distributes, and has prolonged the service life of LED light fixture.The present invention has practiced thrift the energy, has increased substantially the luminous efficiency of LED light fixture, and is simple in structure, easy to use.
