Abstract

The invention relates to a miner lamp used for a mine, in particular to a high-safety miner lamp. The high-safety miner lamp comprises a circuit board, a charging module with the model being TP4056, an LED driving chip with the model being SN 3135, a storage battery and a main and auxiliary LED light source, wherein the charging module is fixed on the circuit board, the circuit board is an aluminum substrate facilitating heat dissipation of the miner lamp, an element on the circuit board is a patch type element and does not fall off easily, the bottom of the charging module is provided with cooling fins, and the cooling fins make contact with the circuit board through heat-conducting glue. Automatic switching between main lamp body lighting and auxiliary lamp lighting of the LED light source is achieved by being controlled by the LED driving chip, a branch voltage can be formed on a second pin of the LED driving chip by the storage battery, the LED driving chip achieves reasonable switching between main lamp body lighting and auxiliary lamp body lighting according to a compared result of the branch voltage and a set undervoltage threshold value, electric energy in the storage battery is reasonably used, lighting time of the LED light source is prolonged, and service life of the storage battery is prolonged.

Description

Technical field [0001] The invention relates to a miner's lamp used in coal mines, in particular to a miner's lamp with high safety performance. Background technique [0002] Miner's lamp is a necessary underground lighting tool for coal miners. It is a special explosion-proof product whose safety performance and quality are closely related to coal mine safety production. The safety of the miner’s lamp is related to the battery inside the miner’s lamp and the use of the light source, while the existing miner’s lamp has few protection measures for the battery. For example, when charging the battery of the miner’s lamp, there is no temperature protection measure, and the battery temperature is too high during the charging process. , The battery is easy to explode, the discharge of the battery is generally extensive discharge, the discharge method cannot be determined according to the battery's own voltage, which will reduce the lighting time of the battery, thus affecting the safet...
