3 the semisealed beam lamp unified socket for H3 halogen electric-light bulb

摘要

The present invention relates to a semi-shielded beam lamp mainly used for lighting or other auxiliary lamps such as transportation and construction heavy equipment, and the socket and reflector are integrally manufactured to enable the use of H3 type halogen bulbs with small size and excellent illumination. It is manufactured to have a stepped part on the socket, and the lens, the reflector and the socket are all made of Pyrex-grade borosilicate glass, which is excellent in waterproof and moisture proof effect, and has excellent weather resistance and thermal shock resistance.;Looking at the configuration through the assembly process, first, the lens 10 and the reflector 20 is formed and processed from a Pyrex-grade borosilicate glass material, and then deposited on the inner surface of the reflector 20 to enable high-brightness reflection. After the lens 10 and the reflecting mirror 20 are brought into contact with each other, the substrate is firmly and hermetically bonded by applying a strong heat to the fusion splicing portion 11, and then the sub reflecting mirror 42 is inserted into the socket 30. In order to insert the H3 halogen bulb 40, the metal washer 52, and the rubber washer 53 in sequence, the wire 54 and the ground wire 46 are drawn out to the outside, and the screw bone of the stopper 50 ( The assembly of the present invention is completed by screwing 51 and the thread 31 of the socket 30.;As described above, the subject innovation is to manufacture the reflector and the socket integrally, but the socket is formed stepped, the diameter of the socket opening is made based on the locking step of the H3 type halogen bulb, the small size of the H3 type bulb It is possible to insert the, and by having a sub reflector and the ground terminal integrally there is no black spots when irradiating light has an effect that the area irradiated is bright, and there is no need to provide a separate ground means.;In addition, the lens and the reflector are made of Pyrex-grade borosilicate glass having the same physical properties, and the inside of the reflector is heated and volatilized in a vacuum to deposit a thin layer on the surface, and is then integrated by glass welding with the lens. By doing so, even when used for a long time is not deformed by the heat or detached from each other, there is another effect that can achieve a perfect waterproof and moisture-proof.
