Transmission-type light distribution method for aircraft landing lamp

Abstract

The invention discloses a transmission-type light distribution method for an aircraft landing lamp, which comprises a radiator base, the left side of the radiator base is fixedly connected with an LED and substrate, the left side of the LED and substrate is movably connected with a primary lens, the outer side of the LED and substrate is sleeved with a second-level lens pressing ring, the surface of the second-level lens pressing ring is movably connected with a second-level lens body, the surface of the second-level lens pressing ring is sleeved with a light shield, the right side of the light shield is fixedly connected with the connecting position of the radiator base, and the left side of an inner cavity of the light shield is movably connected with a third-level lens. Through the radiator base, the LED, the substrate, the second-level lens pressing ring, the second-level lens body, the primary lens, the light shield, the third-level lens and the protective glass, the landing lamp has the advantages of being high in light ray utilization rate and convenient to use, and the problems of low light ray utilization rate, large size and weight and uneven light spots caused by an existing reflection type light distribution method are solved.

Description

technical field [0001] The invention relates to the technical field of aircraft landing lights, in particular to a transmissive light distribution method for aircraft landing lights. Background technique [0002] The existing landing lights all adopt reflective cup light distribution, that is, the landing light source is composed of a group of independent lamp beads arranged in a certain form, and each lamp bead has an independent reflective cup, that is, the reflective light distribution method is used to achieve landing The lamp head light source and reflector cup type light distribution scheme are relatively simple and easy to implement, but they have the following defects: [0003] The utilization rate of the outgoing light is low: the deepest reflector is about 60%. As an airborne light source, the power of the landing light is strictly limited. The low utilization rate will lead to insufficient light intensity of the light source and severe heat generation. In other w...
