Mine lamps, also known as mining lamps or miners' lamps, are specialized lighting devices designed for use in underground mining environments. The requirements for mine lamps are typically governed by regulatory bodies in the countries where they are used, and may vary depending on the specific type of mine and the type of mining operation. However, some general requirements for mine lamps include:

1. Safety: Mine lamps must be designed to be safe for use in hazardous environments, where there may be a risk of explosion or other safety hazards. This may include features such as explosion-proof casings and battery cells, robust and durable construction materials, and mechanisms to prevent accidental ignition.

2. Brightness: Mine lamps must be capable of providing sufficient illumination to allow miners to see clearly in low-light or complete darkness. This may include features such as high-intensity bulbs, reflectors, and lenses to focus the beam of light.

3. Battery life: Mine lamps must have a long enough battery life to last for the duration of a typical shift in a mine. This may require the use of high-capacity batteries or the ability to recharge the battery quickly and easily.

4. Durability: Mine lamps must be able to withstand the harsh conditions of underground mining, including exposure to water, dust, and other environmental factors. The lamp must be designed to be rugged and durable, with components that can withstand shock, vibration, and other types of physical stress.

5. Comfort: Mine lamps must be comfortable for miners to wear for extended periods of time. This may include features such as lightweight construction, adjustable straps, and ergonomic design.

6. Regulatory compliance: Mine lamps must comply with relevant safety regulations and standards in the country or region where they are used. This may include requirements for certifications, testing, and other safety features.
