Explosion-proof lighting

Abstract

The invention provides an anti-explosion illuminating lamp. The anti-explosion illuminating lamp is internally provided with a base of a power module; a rotary shaft is arranged at the lower port of the anti-explosion illuminating lamp; a semispherical rigid protective shell is fixed on the rotary shaft; the protective shell is externally sleeved with a transparent spherical cover, the transparent spherical cover comprises two symmetrical hemispheres and a section of middle cylinder, the inner diameter of the hemispheres is equal to the outer diameter of the rigid protective shell; a stripe hole is formed at a position, intersected with the rotary shaft, on the cylinder; pore teeth are formed at one side of the stripe hole; the pore teeth are meshed with a gear arranged in the stripe hole and fixed on the rotary shaft; when the stripe hole descends to an extreme position, the rigid protective shell rotates to be right above the rotary shaft; when the stripe hole ascends to the extreme position, the rigid protective shell rotates to be right below the rotary shaft and fits to the inner surface of the hemisphere below the transparent spherical shell; the rigid protective shell is lighter than the transparent spherical shell; and a lampwick is arranged in the base. The anti-explosion illuminating lamp not only has a good anti-explosion function, but also cannot affect the appearance and the illumination effect of lamps.

Description

technical field [0001] The invention relates to the lighting field, in particular to an explosion-proof lighting lamp. Background technique [0002] In the field of engineering lighting, due to the complex environment, it is usually necessary to use explosion-proof lamps; however, the current explosion-proof lamps are very rough, and the main protective structure is to wrap metal guardrails outside the bulbs. This structure not only makes the appearance of the lamps very ugly, but also, if If the distribution of metal fences is sparse, it is difficult to play a protective role, and if the distribution of metal fences is dense, it will obviously affect the brightness of the lighting; therefore, the current explosion-proof lighting is not ideal. Contents of the invention [0003] In view of the above problems, the object of the present invention is to provide an explosion-proof lighting lamp, which not only has a good explosion-proof function, but also does not affect the ap...
