LED (Light Emitting Diode) lens for front navigation lamp of airplane

Abstract

The invention discloses an LED (Light Emitting Diode) lens for a front navigation lamp of an airplane. The LED lens comprises an inner total reflection system and an optical prism system, wherein the inner total reflection system is used for collecting light emitted by an LED light source, performing total reflection on the light and causing the light to emit at a small angle; the optical prism system is used for adjusting the emitting direction and optical distribution of the light at the small angle emitted by the inner total reflection system; a groove for collecting the light emitted from the LED light source is arranged on the inner total reflection system. The LED lens can meet the light distribution demand of the front navigation lamp of the airplane; the realizing mode is simple; the LED lens can be integrally formed; the mounting is simpler; the cost is lower; the maintenance difficulty and the maintenance hidden danger are reduced; the application of the LED light source in the front navigation lamp of the airplane is benefited; the LED lens can be widely applied to the front navigation lamp of the airplane.

Description

technical field [0001] The invention relates to an LED lens, in particular to an LED lens used for aircraft front navigation lights. Background technique [0002] As a new lighting source, LED light source is rapidly entering the lighting field. Compared with traditional light sources, LED light source has the advantages of high light efficiency, low energy consumption, long life, high reliability, etc., and has distinct advantages in the lighting field. [0003] With the development of LED technology, LED lighting has gradually penetrated into the field of special lighting. At present, it has been widely used in the fields of automobiles, railways, ships and aerospace. In the field of aerospace, aircraft navigation lights are used to attract the attention of other aircraft flying in the same space when flying at night, so as to avoid collisions between aircraft. Incandescent lamps are mainly used in traditional aircraft navigation lights, which have a limited service life,...

AI Technical Summary

Problems solved by technology

The current lenses used for LED light sources generally can only simply gather or diffuse the light, which cannot meet the figure 1 and figure 2 The light distribution requirements of the aircraft's front navigation lights, so it may be necessary to use multiple LED light sources combined with multiple lenses or supplementary lighting to realize the front navigation lights solution. It is also large, which is not conducive to the application of LED light sources in aircraft front navigation lights
