Projection type emergency escape light source device suitable for underground workshop

Abstract

The invention discloses a projection type emergency escape light source device suitable for an underground workshop. The projection type emergency escape light source device comprises a ground projection lamp, a light sensing device, LED illuminating lamps and a control circuit board, wherein the control circuit board is arranged in a device lamp box; the ground projection lamp and the light sensing device are located below the device lamp box; the LED illuminating lamps are located above the device lamp box; the ground projection lamp, the light sensing device and the LED illuminating lamps are connected with the control circuit board separately; the control circuit board comprises a charging management module, an emergency switching module, a battery capacity testing module, a single-chip microcomputer module and a state indicating lamp, wherein the single-chip microcomputer module is connected with the charging management module, the emergency switching module and the battery capacity testing module separately, and is also connected with the state indicating lamp; when 220V alternating current is used for supplying power, a safety outlet identification is turned on constantly; and when the alternating current is interrupted and when an internal lithium battery pack supplies power, the ground projection lamp is used for clearly projecting the emergency escape identification to the ground outside two meters, so that an important escape identification is provided when illumination interruption of the underground plant occurs, thereby providing precious help for emergency escape.

Description

technical field [0001] The invention relates to the technical field of electrical equipment, in particular to a projection type emergency escape light source device suitable for underground workshops. Background technique [0002] When the 220V AC lighting power supply of the underground workshop is interrupted, the underground workshop will be completely dark. Traditional emergency lights are usually installed on the wall, and can only indicate the direction of emergency escape through the blue and white backlight on the wall. It is worth noting that the walls of underground workshops are usually equipped with equipment and facilities such as maintenance power boxes, switchboards, and hand-held fire extinguishing devices. Personnel escape along the wall along the wall markings in a dark environment, and the equipment and facilities near the wall can easily become obstacles for personnel to escape. [0003] The device of the present invention realizes that when the 220V AC...
