Problems solved by technology

In this way, when the search light works in this environment, its bulb often breaks
In addition, since the positive and negative poles of the xenon arc lamp are located at both ends of the xenon arc lamp, when the xenon arc lamp is installed, the positive pole is inserted into the anode conductive end at the end of the search lamp lamp housing, and the negative pole is placed in the lamp housing. The cathode wire at the front end of the inner cavity is directly connected; in this way, when the search light is subjected to strong bumps, the negative electrode of the bulb and the cathode wire interface will be disconnected due to loosening, which will bring difficulties to night work.

Abstract

The invention discloses a device for fixing a search lamp bulb, which comprises a light transmitting cover and a bracket, wherein the light transmitting cover is in a cup-shaped structure, and the bottom center of the light transmitting cover is provided with a first cathode conducting hole for plugging the negative pole of the bulb; one end of the bracket is connected with the bottom surface of the light transmitting cover, and the other end of the bracket is provided with a connecting block on which a lead connecting hole is arranged. Compared with the prior art, the device for fixing the search lamp bulb can effectively prevent the bulb from being broken and prevent the circuit break phenomenon of the bulb from occurring.

Description

technical field [0001] The invention relates to a light bulb fixing device, in particular to a search light bulb fixing device. Background technique [0002] Search lights are widely used in aviation or shipping fields due to their high brightness and long projection distance. Usually, search lights are installed on aviation rescue planes or ships and warships, and their working environment often has strong vibration or bumpiness; moreover, the bulbs of existing search lights generally adopt elongated xenon arc lamps. In this way, when the search light works in this environment, its bulb often breaks. In addition, since the positive and negative poles of the xenon arc lamp are located at both ends of the xenon arc lamp, when the xenon arc lamp is installed, the positive pole is inserted into the anode conductive end at the end of the search lamp lamp housing, and the negative pole is placed in the lamp housing. The cathode wire at the front end of the inner cavity is direc...
