A. Split type composition: explosion-proof lamps + explosion-proof emergency electrical box (built-in emergency circuit board and conventional energy-saving and environmentally friendly lithium battery packs or old lead-acid battery packs on the market).
Advantages: Split type explosion-proof emergency light Because the explosion-proof electrical box and the lamp are separated, the working temperature of the lamp will not affect the emergency circuit board and battery in the explosion-proof electrical box, improving the explosion-proof performance and the life of the emergency circuit board and battery.
Disadvantages: The split type increases the cost and installation time due to the addition of an explosion-proof electrical box shell.
B. Integrated composition: The integrated design of explosion-proof lamps and electrical boxes is directly equipped with emergency circuit boards and battery packs, eliminating the need for explosion-proof electrical boxes.
Advantages: The one-piece explosion-proof lamp is cheap and easy to install.
Disadvantages: The integrated explosion-proof emergency light can only be used with low power, and the power will affect the service life of the circuit board and battery.
