LED emergency light is a type of lighting that can be used to provide a light source during a power outage that is not expected. LED performance, however, is not just Dependent on the quality of the LED light, but also on the charging circuit, discharge control, battery and electrical protection system. Charging currents that are too high or too low, or uncontrolled battery discharge, can reduce battery life and even cause battery failure.
Controlled charging and discharge protection is also a vital part of the correct design of an emergency lighting system to ensure that the system operates safely and has reliable backup times and system life.
These features are essential at industrial plants and commercial buildings, warehouses, hospitals and other locations that need illumination for safety or the continuous operation of the facility.
Pyrotech Technologies Pvt. Ltd. provides LED Emergency Lighting and Emergency Driver Solutions to provide alternate illumination in case of any power failure. Depending on the product specification, it will have protection features such as battery overcharge, over-discharge, over-voltage, under-voltage, and short-circuit protection in its emergency kits.
Key Benefits of Proper Battery Charging and Discharge Protection
Knowing Battery Charging Current and Discharge Current
What is the battery charging current?
Charging current refers to the electrical current that is applied to a rechargeable battery during the charging process. LED emergency Illumination is a lighting system in which the storage battery is charged during the standard electrical power.
The charging current shall be suitable for the battery chemistry, temperature capacity, and manufacturer's charging specifications. Depending on the type of battery and charging design, the system can be either constant current or constant voltage charging or controlled maintenance.
If you follow good charging circuit design, overcharging, overheating, and additional battery degradation will be avoided.
What is Battery Discharge current?
Discharge current is the current that will be drawn from the battery when the power goes out to run the LED light.
Discharge current is based upon the LED load, battery voltage, driver efficiency, and desired backup time. For instance, if you have a three-hour backup system, you would need a matching battery and emergency driver to provide the load for that duration at given operating conditions.
The over-discharge protection prevents the battery from being discharged to the limits.
Charging Current vs. Discharge Current
| Parameter | Charging current | Discharge current |
| Purpose | Recharges the battery | Power the LED during an outage |
| When it operates | During the charging period | During battery- powered operation |
| Main design requirement | Safe, controlled charging | Required light output and backup duration |
| Main protection concern | Overcharging & heat buildup | Excessive or deep discharge |
| Performance benefits | Supports battery health | Supports reliable emergency lighting |
Technical Details of LED Emergency Lighting Systems
The following specifications are published for Pyrotech's emergency kit and LED emergency lighting solutions. Exact values depend on the selected model.
Pyrotech Technologies Pvt. Ltd. offers LED Lighting and LED Driver solutions that are tailored to meet the needs of consistent lighting, electrical protection and performance in industrial/commercial applications.
Pyrotech Products: Reliable Emergency Lighting
Emergency Kit / Emergency LED Driver: Power backup for LED loads compatible when the power goes out. The following protection types are included in integrated protection: over-charging, over-discharge, over-voltage, under-voltage and short circuit protection.
LED Emergency Light: Backs up the power during unexpected power outages, helping to keep corridors, stairs, offices and designated emergency exit routes illuminated.
Industrial Emergency Light: Emergency illumination for industrial buildings, production areas, warehouses, and maintenance areas that are required to be visible for operating and work there safely.
Flameproof Emergency Light: For zones where flammable gases may be present, the product selected must be properly certified for the hazardous zones classification. The product selected must meet certification requirements for the hazardous zones classification
LED Drivers and Ballast Solutions: Control electrical energy to LED lighting. Stable operation is achieved by suitable driver designs; battery-powered lighting can be performed by compatible emergency drivers during mains failure.
How Battery Protection Works During Operation
A properly designed emergency lighting system manages three important operating stages:
Overall Application Areas
If a loss of light in one area may pose a safety hazard or affect necessary tasks, then LED emergency lights and/or battery-back emergency lighting may be beneficial.
Industrial plants: maintenance areas, Production floors and Selected emergency access routes. Selected operating areas, service corridors and essential access locations at power plants.
Cement and Steel industries: Work areas and designated routes.
Logistics and warehouse: Loading areas, emergency exits and storage.
Healthcare and hospital: staircases, emergency lighting and corridors.
Commercial buildings: hotels, public areas, shopping centres and Offices.
Infrastructure projects: stairwells, passages and escape routes.
Lighting requirements include the light level needed, environmental factors, backup power time, safety codes and mounting layout.
Certificates, Approvals and Compliance
We release information about product test results. Our certificate items include PESO approval for flameproof well-glass lighting and RITES references, IP protection testing, surge testing, and relevant IEC standards.
We also mention testing voltage, thermal stability and EMC compliance according to corresponding IEC standards for emergency kits.
