Problems solved by technology

Mainly: the safety performance of lithium batteries is poor, although the protection circuit is added, there are still serious accidents of battery pack burning and explosion
Poor safety is still the main problem of mining hat lights
In addition, after the miner's lamp is switched to lithium-ion batteries, the original charging rack cannot charge the lithium battery miner's lamp, and the mine must replace the charging rack, resulting in a huge waste of resources

Abstract

The semiconductor lamp for miner's cap with discharge and recharge control and protection system consists of lamp socket, electric cable and rechargeable battery. The lamp socket casing, lamp, reflector, lens and cover; and the rechargeable battery includes casing, battery, top cap, wire clamp and bottom sheet. The present invention features the semiconductor lamp with radiating fins, the focusing hood in front of the lamp, the discharge and recharge control circuit on the circuit board behind the lamp, the lithium battery, the charge, and the discharge and short-circuit protecting circuit on circuit board inside the bottom sheet. The present invention has the advantages of small size, light weight, less maintenance, safety and other advantages, and may be sued in various kinds of mines

Description

1. Technical field [0001] The invention belongs to mine lamps, in particular to a semiconductor lighting mine cap lamp with its own charging and discharging control and protection system. 2. Background technology [0002] Existing mine cap lamp is made up of mine cap lamp holder, cable wire and rechargeable battery; Battery power supply is lead-acid battery mostly, uses common incandescent bulb in the lamp holder. CN 208129U patent " a kind of less maintenance lead-acid storage battery cap is used miner's lamp " as disclosed in China. They are larger in size, heavier in weight, short in service life, and heavy in maintenance workload, and their safety performance is still relatively poor especially in coal mines. [0003] In order to reduce the size and weight, lithium batteries have been used in mining cap lamps in recent years. In the practical popularization and application of this novel miner's lamp, many serious problems have been found. Mainly include: the safety pe...
