Underground passive beta emergency access indicating lamp

Abstract

The invention discloses an underground passive beta emergency access indicating lamp, and relates to a passive indicating lamp which is designed to be fully sealed, safe, explosionproof and suitable for underground coal mine and non-coal mine emergency accesses. According to the technical scheme, the underground passive beta emergency access indicating lamp comprises a shell with an indicating pattern, and a luminophor, the luminophor is mounted in the shell, the passive luminophor is adopted by the indicating lamp, and comprises a tritium tube and a high-transparency epoxy resin body, and thetritium tube is poured and sealed in the high-transparency epoxy resin body. The surface of the high-transparency epoxy resin body is sequentially coated with a reflection layer and a protection layer, the indicating pattern is arranged on the front face of the high-transparency epoxy resin body, and the surface of the indicating pattern is not covered with a coating. The high-transparency epoxyresin body is provided with a frame for protecting the passive luminophor.

Description

technical field [0001] The invention relates to a passive indicator light used for emergency passages in underground coal mines and non-coal mines. Background technique [0002] Tritium tube, also known as tritium lamp or beta lamp, is a light-emitting device made of the radioactivity of tritium, a hydrogen isotope. Its main structure is to fill a closed glass tube with tritium gas, which is released by tritium during beta decay. The electrons hit the phosphor powder coated inside the glass tube, which fluoresces. This process is called radioluminescence. The luminescence of tritium tubes does not need to receive electrical energy from the outside world, so it is often used in warning devices and watches. In recent years, light-emitting devices similar to tritium tubes have replaced traditional light sources made of highly radioactive and harmful elements such as radium. [0003] Both underground coal mines and non-coal mine emergency passages require indicator lights. T...

Problems solved by technology

[0004] This traditional emergency channel indicator light that requires external power supply needs to be wired. When the power is off, it can only light up for a few hours by relying on the internal backup rechargeable battery. The internal step-down circuit will generate a certain amount of heat due to long-term power-on operation, which will cause the loss of original devices.
