In actual construction engineering, the emergency lighting power supply should be selected according to the structure of the layer number, size, complexity, how many buildings stay and mobile people, the production and use of building characteristics, fire danger degree and the importance of the buildings, and other emergency power Settings And so on, comprehensive consideration for technical and economic analysis and comparison, choose the optimal emergency lighting power supply. The combination power supply mode has the advantages of more than two kinds of power supply, and the unilateral disadvantages can complement each other. Although the investment is large, it is still widely used in high-rise buildings and some particularly important large buildings due to its high reliability.

Emergency light is the general term of lamps and lanterns used for emergency lighting. Reasonable choice of power supply and control mode and wiring mode of emergency lighting system and good daily maintenance work directly affect the play of the role of fire emergency lighting system. Let's talk about the principle of emergency light. Classification of emergency lights Emergency lights are mainly divided into: double-headed emergency lights, hand-held emergency lights, fire emergency lights, LED emergency lights, energy-saving emergency lights, explosion-proof emergency lights, underwater emergency lights, rechargeable emergency lights, solar emergency lights, multi-functional emergency lights.

Rechargeable lifting emergency light is an integrated portable DC mobile lighting system. It is composed of chassis, pneumatic lift lamp pole, 2X180W high brightness LED light source, rechargeable battery pack, control system and other parts. Rechargeable lift emergency working light comes with battery, automatic rise, fall, light source using 180W high brightness LED light source, green environmental protection; The whole equipment has reasonable structure and convenient operation. Scope of application: Rechargeable lifting emergency lights are widely used in all kinds of night emergency lighting, operation construction, engineering repair, and other occasions, to meet the needs of large area of lighting on site.

The guide plate is a new type of vehicle-type traffic light. The guide card set is composed of left and right display card and operation control box, exquisite and beautiful in appearance, simple in operation and easy to install. Its advantages are overall light weight, low power consumption during use, long service life, long visual distance, good visual effect. The guide plate is widely used, such as engineering emergency vehicle, sprinkler, road construction vehicle, road maintenance vehicle, road sweeper and road warning signs.

1. Suitable for any type of car, low power consumption, rainproof and waterproof. 2, light weight, movable, easy to use. 3, high brightness, omnidirectional, can be attached to the roof or other metal. 4. Powered by car battery, no need to worry about insufficient power supply. 5. Equipped with tripod and extended wire, it is more convenient to illuminate long-distance targets.

Illuminating distance special light distribution design, high reflective efficiency, light concentration, strong. The lighting source adopts imported titanium metal tungsten halogen bulb or xenon headlamp of advanced car, which can make full use of 12V large-capacity battery of automobile (12V), ship (24V) and other mechanical and electrical equipment for a long time; It can also be equipped with large capacity high-energy battery lighting.

It is suitable for all kinds of high altitude and wilderness operations to omni-directional, multi-angle, long-distance and large-scale inspection, search, tracking, rescue and operation construction; If railway, electric power, public security, iron and steel, petrochemical and other units project lighting car, patrol car, accident repair car, etc
