Problems solved by technology

However, there are two problems in the existing explosion-proof headlights: 1. The battery only has a single protection. When the battery management module fails, it is easy to cause overcharge and overdischarge, or even short circuit, causing an explosion accident; The light distribution device must work with a larger current to achieve the same illuminance, so the battery capacity is large, the headlight is heavy, and it is inconvenient to carry and use

Abstract

A minisize explosion-proof lamp comprises a lamp cap device and a battery device, wherein the battery device is provided with a battery box, the lamp cap device is electrically connected with the battery box which is provided with a dual-protection circuit for maintaining normal operation of the battery. The dual-protection circuit comprises an electrically connected voltage shaping circuit for storing electric charge and smoothing waveform of the battery voltage, a current-limiting circuit for sampling voltage and limiting current, a charging-discharging switch circuit and a battery management module for controlling the charging-discharging switch circuit to charge and discharge the battery. The invention not only reduces the volume of the optical assembly and the whole weight of the lamp cap device, but also reduces potential accident probability.

Description

technical field [0001] The invention relates to the field of explosion-proof lamps, in particular to a miniature explosion-proof headlamp which can be used in inflammable and explosive environments. Background technique [0002] Explosion-proof headlights are usually used in harsh environments, so explosion-proof performance is required for explosion-proof headlights. In the existing technology, the design of the explosion-proof headlight usually includes three parts: optical design, structural design and circuit design. However, there are two problems in the existing explosion-proof headlights: 1. The battery only has a single protection. When the battery management module fails, it is easy to cause overcharge and overdischarge, or even short circuit, causing explosion accidents; 2. The use of reflectors and other common The light distribution device must work with a larger current to achieve the same illuminance, so the battery capacity is large, the headlight is heavy, a...
