Novel automatic exhaust light projecting lamp

Abstract

The invention relates to a novel automatic exhaust light projecting lamp. At present, light projecting lamps have the disadvantages that the design in the safety aspect is not enough, the sealing performance of the lamps is poor, short circuit can be caused by water leakage, electrical elements and bulbs in the lamps can be burned out; if the light projecting lamps are sealed, the gas in the lamps can not be exhausted when lamp emitters generate gas pressure as the bulbs are lightened, and the lamps can explode to cause potential safety hazard. In the invention, the sealing performance is good, a rear cover of a lamp holder is provided with an automatic exhaust valve, and once the bulb is lightened, gas pressure is generated in the lamp; if the pressure exceeds the standard pressure, the automatic exhaust valve exhausts automatically and then seals automatically when the pressure is normal after gas exhaust. The invention reaches the requirement on lamp seal performance and ensures the service life of electrical elements and bulbs.

Description

technical field [0001] The invention belongs to the lamp industry, in particular to a novel automatic exhaust light projection lamp. technical background [0002] At present, the safety design of floodlights in the market is insufficient, the sealing of the lamps is poor, and the water leakage of the lamps often causes a short circuit of the power supply, which burns out the internal electrical components and bulbs of the lamps. [0003] If the floodlights are designed to be sealed and the light bulbs are turned on, air pressure will be generated in the emitter of the lamps, and the gas cannot be discharged, causing the lamps to explode and bring safety hazards. Contents of the invention [0004] The purpose of the present invention is to overcome the design deficiency of the above-mentioned flood-lighting lamp, and to provide a new type of automatic exhaust flood-light lamp. Automatic exhaust valve device, which consists of: lamp surface glass, sealing ring, lamp head ri...

Problems solved by technology

[0002] At present, the safety design of floodlights in the market is insufficient, the sealing of the lamps is poor, and the water leakage of the lamps often causes a short circuit of the power supply, and burns out the internal electrical components and bulbs of the lamps.

[0003] If the design of the spotlight lamp is sealed, the lamp lights up the bulb, the air pressure is generated in the emitter of the lamp, and the gas cannot be discharged, causing the lamp to explode and bring safety hazards
