Abstract
The utility model discloses a semiconductor cold light aft sidelight for an airplane, including a lamp head, a lamp holder arranged in the lamp head and a connection point arranged at the bottom of the lamp head. The connection point connects with one end of a wire arranged in the lamp head; the other end of the wire connects with an electric bridge arranged in the lamp head; a circuit board arranged on the end of the lamp holder connects with the electric bridge, and a voltage-dropping and current-limiting resistor and a semiconductor LED are mounted on the circuit board. The utility model is reasonably designed, has a simple structure, works stably, has perfect aseismic capacity, a long lifespan, and appreciable electricity-saving effect and is universal. And the original electrical and mechanical interfaces of the light source need not to be changed, so the utility is convenient for use and maintenance, and the cost is low.
Description
Technical field
The utility model relates to a kind of aircraft semiconductor cold light source tail navigation lights.
Background technology
At present, illumination of using on the home-built aircraft and information light source all adopt traditional incandescent lamp, and incandescent lamp belongs to heat radiation light source.This intensity of light is low, hear rate is big, visual range is short, shock resistance is poor, service life is short, working service is inconvenient.As the average night flight of the FJ28 type bulb service life as airplane external illuminating be 1/10～1/20 of projected life, promptly 5～10 hours, not only cause the material damage supply amount big, use and keep in repair inconvenience, and directly influence flight safety and training.
The utility model content
The purpose of this utility model is the deficiency that exists at existing light source technology, and a kind of reasonable in design, simple in structure, reliable working performance, shock resistance is strong, the life-span is long, power savings is obvious, versatility is good, working service is convenient, cost is low aircraft semiconductor cold light source tail navigation lights are provided.
The technical solution of the utility model is: a kind of aircraft semiconductor cold light source tail navigation lights, comprise lamp holder 1, be arranged on lamp holder 2 in the lamp holder 1 and the contact 3 that is arranged on lamp holder 1 bottom, it is characterized in that: an end of the lead 4 that described contact 3 is interior with being arranged on lamp holder 1 is connected; The other end of lead 4 is connected with electric bridge 5 in being arranged on lamp holder 1; The circuit board 6 that is arranged on lamp holder 2 ports links to each other with electric bridge 5, and step-down current-limiting resistance 8 and semiconductor light-emitting-diode 7 are installed on the circuit board 6.
The utility model is compared with existing light source technology and had the following advantages: the utility model is reasonable in design, simple in structure, reliable working performance, shock resistance is strong, the life-span is long, and power savings is obvious, versatility good, working service is convenient, cost is low.
