Description

technical field [0001] The invention relates to an explosion-proof lamp in an explosion-proof environment, in particular to a light-emitting assembly for an explosion-proof explosion-proof lamp and to an explosion-proof explosion-proof lamp. Background technique [0002] A device or appliance that converts electrical energy into light energy to provide luminous flux can be called an electric light source. Electric light sources are divided into thermal radiation light sources, gas discharge light sources and field-induced light sources according to their different luminous principles. Among them, incandescent lamps and halogen tungsten lamps are heat radiation light sources and are the first generation light sources; ordinary fluorescent lamps, energy-saving lamps and low-pressure sodium lamps belong to low-pressure discharge lamps in gas discharge light sources and are the second-generation light sources; high-pressure sodium lamps, high-pressure mercury lamps and The meta...

AI Technical Summary

Problems solved by technology

[0008] a. Luminous efficiency problem: The theoretical luminous efficacy of electrodeless lamps is only 80Lm / W, while the actual product luminous efficacy is only 65Lm / W, comparable to energy-saving lamps. Although it is better than incandescent lamps, it cannot be compared with the "sodium lamps" currently used in street lamps. / Metal halide lamp" compared with (sodium lamp / metal halide lighting effect 110-120Lm / W)

[0009] b. Electromagnetic interference and space electromagnetic radiation problems: Electrodeless lamps rely on "electromagnetic waves or microwaves" to work, and their microwave generators emit ultra-high-power electromagnetic waves, with a transmission distance of up to a thousand kilometers, and become an unsolvable "interference source" at short distances. , and even a serious accident of "electrodeless lights interfering with the aviation navigation system"

[0013] 3) The electromagnetic interference and space electromagnetic radiation of the gas discharge lamp are high,

[0014] 4) The stroboscopic problem of the gas discharge lamp is serious,

[0015] 5) The gas discharge lamp takes a long time to start,

[0016] 6) Gas discharge lighting has low efficiency and thus high power consumption

[0017] In addition, in the LED lamps currently on the market, the LED light source module and the lamp are integrally fixed (for example, glued to the lamp body) and cannot be disassembled. Therefore, if the LED is damaged, it needs to be destructively removed and replaced, which is complicated to replace and maintain. , and even had to return the whole lamp to the factory for processing. This process is complicated and time-consuming, resulting in a waste of manpower and material resources.
