Emergency lighting is a type of lamps that can effectively light up and display evacuation channels when normal lighting power failures, can effectively light up and display evacuation channels, or continue to light up and uninterrupted work.Widely used in public places and places that cannot be interrupted.
How to use emergency lighting
"Fire Fire Standards for Architecture" and "Fire Fire Standards for High -rise Civil Building Design" to be closed stairs, smoke -proof staircases and their former rooms, audience halls, exhibition halls, multi -functional halls, restaurants, and commercial departments of public buildingsThe evacuation aisle in public buildings should be clearly provided for emergency lighting and evacuation indicator lamps.
Principles of emergency lighting work
220V AC power supply through C1 lowered voltage (R1 is a discharge resistance), VD1 ~ VD4 rectification, C2 filtering to electromagnetic relay J with a conversion contact, provides a DC current of about 100mA to suck it, J-1 guide, charging charging, charging, charging, charging, chargingThe circuit is charged by the battery GB through VD5.When LED1 and LED2 are on, the indication is charging.
Emergency lighting model
YYJD-ZZ-66 emergency light, using switching power control circuit, stable performance, can adapt to a loose voltage environment; micro-treatment centralized control technology, US FairchildPWMIC voltage voltage technology; Hengli constant voltage voltage power supply technology, effectively enhances the service life of the battery.Intelligent faults are automatically detected, and performance is stable; high -quality nickel -cadmium batteries, large battery capacity; patch process, stable product quality; LED light source, energy saving and environmental protection, long service life.
Emergency lighting price
The light source is a 2D tube, 11W or 16W, the lighting time is not less than 3 hours. The charging method is a floating -charged top -suction emergency lighting light. The lowest price is 220 yuan/set. The cheaper quality is not reliable.many.Supplement: What kind of human induction, iron leather paint base, ordinary plastic lampshade, and lighting for the longest period of 90 minutes (the brightness is equivalent to 8W, the actual power consumption is rarely) The actual price should be 60 ~ 80 yuan/setEssence
Emergency lighting installation specification
First, in addition to normal power supply, there should be another spare power supply.The two must take reliable measures to prevent side -to -town operations.Second, the conversion time of the two -way power supply: evacuation and lighting and spare lighting are not greater than 15s; finance, stores, and exchange spare lighting is not more than 1.5s; safety lighting is not greater than 0.5s.Third, the height of the safety export logo is not less than 2m from the ground, and it is installed above the evacuation exit and the inside of the stairs.Fourth, the evacuation signs are installed on the top of the safe outlet, and the staircase, evacuation aisle and turning should be installed on the wall below 1m.If the conditions are not available, it can be installed in the upper part.The distance between the logo lamps on the evacuation channel is not more than 20m, and the civil defense engineering is not more than 10m.
