Problems solved by technology

Indicator lights are usually used to reflect the working state of the circuit (with or without electricity), the working state of electrical equipment (running, outage or test) and position state (closed or disconnected), etc., and its function is to prompt or warn people. However, the currently used indicator lights have certain limitations in use. For example, when in use, the lamps cannot play an explosion-proof effect, and the life of the indicator lights is short, and when in use, the distance between the electronic components and the housing Smaller, it is easy to affect the working efficiency of the lamps, and the currently used indicator lamps cannot solve these disadvantages very well, and have certain limitations

Abstract

The invention discloses an explosion-proof indicating lamp. The explosion-proof indicating lamp comprises a casing, an indicating lamp nameplate is embedded into the upper surface of the casing, an LED lamp is embedded into the casing, a transparent part is arranged in one side of the LED lamp, a chromatic circle resistor and a fuse are welded to the other side of the LED lamp, one end of the chromatic circle resistor and one end of the fuse are welded to cables respectively, and the internal of the casing is filled with a gum compound. The explosion-proof indicating lamp is reasonable in design and has practical functions, the fuse is arranged to protect a circuit effectively, and as a temperature protective fuse device, the fuse can ensure that epoxy resin works within an effective temperature range effectively, the internal of the lamp is filled with the epoxy resin material in the thickness of 0.2-0.5cm, the transparent part of a silica gel material can increase the transmittance effectively, and the working efficiency of the lamp is further improved; and the explosion-proof indicating lamp is diversified in structure, comprehensive in functions and suitable for widely popularization.

Description

technical field [0001] The invention relates to the technical field of lighting equipment, in particular to an explosion-proof indicator light. Background technique [0002] An indicator light is a device that uses light to monitor the working or position status of circuits and electrical equipment. Indicator lights are usually used to reflect the working state of the circuit (with or without electricity), the working state of electrical equipment (running, outage or test) and position state (closed or disconnected), etc., and its function is to prompt or warn people. However, the currently used indicator lights have certain limitations in use. For example, when in use, the lamps cannot play an explosion-proof effect, and the life of the indicator lights is short, and when in use, the distance between the electronic components and the housing Smaller, it is easy to affect the working efficiency of the lamps, and the currently used indicator lamps cannot solve these disadvan...
