Description

TECHNICAL FIELD

[0001] The present application relates to the field of lamp technology, in particular to an explosion-proof lamp. BACKGROUND

[0002] At present, most of the LED explosion-proof lamps on the market only have basic lighting functions, and are limited by explosion-proof standards and the design requirements of traditional explosion-proof lamps, lacking intelligent control functions. With the rapid development of intelligent technology, traditional single-function lamps have been unable to meet the growing market demand. The few existing explosion-proof lamps with intelligent control functions usually use dial switches or knob switches to achieve power and color temperature adjustment. Although this adjustment method is common in ordinary LED lamps, due to the strict requirements of explosion-proof standards, this method has potential risks in environments where electrical components may generate electric arcs or sparks, and therefore is only suitable for Division 1 hazardous areas, not for Division 2 hazardous areas.

[0003] In Division 1 hazardous areas, explosion-proof lamps must use explosion-proof enclosures as explosion-proof types to ensure the safety of the lamps in explosive environments. However, the use of explosion-proof enclosures not only increases the volume, weight and structural thickness of the lamps, but also leads to complex production processes and high costs. In addition, for intelligent control, the cover must be adjusted, and the continuity of the explosion-proof surface must be ensured after the control is completed, otherwise it will cause explosion-proof failure, which puts higher requirements on the safety and reliability of the equipment. In contrast, explosion-proof lamps in Division 2 hazardous areas are not strictly required to use explosion-proof enclosures, so the structural design is more flexible and can reduce safety risks, but existing explosion-proof lamps still cannot effectively solve the problem of power and color temperature control.

[0004] Therefore, how to improve the control function of LED explosion-proof lamps in Division 2 areas, especially the power and color temperature control, while ensuring explosion-proof safety, is a key problem to be solved in current technical development. CONTENT OF THE INVENTION
