Description

Technical Field

[0001] The utility model belongs to the technical field of lighting fixtures, and in particular relates to an LED explosion-proof lamp. Background Art

[0002] With the rapid development of industries such as petroleum, chemical industry, and mining, lighting fixtures are increasingly used in production, storage, and rescue, and there are more and more varieties. How to prevent accidental explosions of lighting fixtures in dangerous places with explosive gases has become a very important issue. Since lighting fixtures inevitably generate sparks or form hot surfaces when working, once they encounter explosive gas mixtures at the production or rescue site, they will cause explosion accidents, directly endangering national property and the lives of citizens. Therefore, as the most widely used lighting fixtures, its explosion-proof technology issues have long attracted widespread attention and great attention.

[0003] To this end, while ensuring the lighting of dangerous places such as gas stations, people have invented explosion-proof lamps to prevent explosion accidents caused by lighting. Explosion-proof lamps are used in the presence of flammable gases and dust, which can prevent the arc, sparks and high temperature that may be generated inside the lamp from igniting the flammable gases and dust in the surrounding environment, thereby meeting the explosion-proof requirements. Currently available LED explosion-proof lamps usually irradiate with high-intensity light, and the traditional lens structure has the disadvantages of: the light is not concentrated enough and it is easy to cause dazzle.

[0014] Compared with the prior art, the advantages of the utility model are: the utility model has an explosion-proof layer, a sealing groove, significant heat dissipation, rust-proof and durable, and also improves the lens plate that is not sufficiently concentrated and easily causes dazzle to people. By designing the convex lenses on the lens plate to be convex lenses with an optical angle of 60°, a more focused lighting effect can be obtained. Because the light source plate and the lens plate are installed in a fitting manner, the focal lengths of the two are fixed and known, the focusing effect can be improved based on the principle that the smaller the optical angle, the more focused the light. The inner side of the radiator is also provided with a reflective coating. Such a design can further reflect the light directed to the outside to achieve convergence, thereby making the light more concentrated, so that users have a better lighting effect while not easily causing dazzle to the human eye due to insufficient light concentration.
