What is a miner's lamp?

LED miner's lamp adopts the 4th generation light source. Compared with incandescent lamp, high-pressure sodium lamp, high-pressure mercury lamp, electrodeless lamp and other light sources, it has the following advantages: voltage: LED miner's lamp adopts low-voltage power supply, and the single voltage is between 1.9-4V, which is safer than using high-voltage power supply. Efficiency: high luminous efficiency, which has reached the highest luminous efficiency in the laboratory at present? 16 1 lm/w(cree) is the lighting product with the highest luminous efficiency at present. Theoretically, the luminous efficiency of LED per watt is as high as 370 lm/w, and it is no problem for LED to reach per watt 150LM with good technology under the condition that the current chip structure remains unchanged. At this brightness, basically all lighting fields can be replaced. It is predicted that in the next 1 ~ 3 years, the LED light source will reach the light efficiency of 300 lumens per watt. At present, the LED in American laboratories has reached the luminous efficiency per watt 16 1 lumen, and the total luminous flux is 175 LM. Earthquake resistance: LED is a solid-state light source, which has unparalleled earthquake resistance due to its particularity. Stability: 654.38+100000 hours, and light attenuation is 70% of the initial value.
