Embodiment Construction

[0017] The infrared anti-reflection film enclosed incandescent lamp is composed of a lens (or screen) 1, a luminous body 2, a reflector (commonly known as "cone") 3, an infrared anti-reflection film 4, a guide wire 5 and a contact piece 6, and the illuminant 2 is welded A mounting part is formed on the guide wire 5, and placed on the focal point of the reflector (commonly known as "cone") 3, the inner surface of reflector (commonly known as "cone") 3 is a paraboloid, and the inner wall of the paraboloid is coated with an infrared anti-reflection film 4, and the lens (or screen) 1 and the reflector (commonly known as "cone") 3 are edge sealed to form a sealed glass cavity, and then the air is exhausted on the exhaust car and filled with inert gas to seal it off, and finally the contact piece is welded on the lead-out electrode 6.

[0018] In the present embodiment, the infrared anti-reflection film 4 is formed by alternately and uniformly vapor-depositing ZnS coating and SiO on...

Abstract

The infrared anti-reflection film enclosed incandescent lamp and the preparation method of the infrared anti-reflection film is an infrared anti-reflection film enclosed incandescent lamp for aircraft landing and taxiing, which is composed of a lens, a luminous body, a reflector, a guide wire and a contact sheet. Welded on the guide wire to form a mounting piece, placed on the focal point of the reflector, the lens and the reflector are edge-sealed to form a sealed glass cavity, and the inner wall of the parabola of the reflector is coated with an infrared anti-reflection film, and the infrared anti-reflection The film adopts the evaporation coating method. The steps of evaporation are degassing before plating, ZnS coating first, SiO2 coating after, alternating and uniform evaporation, and finally aging and firming. Using infrared anti-reflection film instead of aluminum film can effectively solve the problem. In addition to the problem of PAR lamp explosion, it improves the luminous intensity and life of the bulb, reduces the loss of quality, and improves social and economic benefits.

Description

technical field [0001] The invention relates to an infrared anti-reflection film enclosed incandescent lamp, in particular to an infrared anti-reflection film enclosed incandescent lamp for aircraft landing and taxiing. Background technique [0002] At present, high-power enclosed incandescent lamps are generally used as light sources for aircraft landing and taxiing. The illuminants are usually incandescent filaments (or tungsten-halogen wicks), which are made according to the principle of thermal radiation luminescence. Usually, the filaments are heated to incandescence by electric energy to emit light. The general life of the lamp is about ten hours, the effective irradiation distance is 30 meters, the beam divergence angle is 12 degrees horizontally, 8 degrees vertically, and the color temperature is 2800-3200K. The lamp's reflector (commonly known as the "cone") and lens (or screen) are composed of precisely pressed glass elements. The inner su...
