What is the Gas Station LED Canopy Light?

Gas Station LED Canopy Light is a specialized type of LED luminaire designed specifically for illuminating the canopies of gas stations. It is typically installed under the gas station canopy using either pendant or recessed mounting methods, aiming to deliver bright, uniform, and efficient illumination to ensure safety and visibility at the gas station.

What is an emergency battery backup（UPS- uninterruptible power supply）?

Emergency battery backup, canopy light with battery backup also known as an Uninterruptible Power Supply (UPS), is a device used to provide power backup. Its primary function is to offer short-term electrical supply to critical equipment in the event of a main power failure or outage.

A UPS typically consists of batteries and a controller, which can convert electrical energy into direct current (DC) and supply it to the equipment when needed. When the main power is available, the UPS automatically charges the batteries to maintain their charge. Once the main power is interrupted, the UPS detects it and switches to the backup battery power immediately, ensuring continuous power supply to the equipment.

Types of batteries used in UPS systems include:

Sealed Lead Acid (SLA) batteries: These are the earliest types used in emergency lighting systems. Canopy light with battery backup are cost-effective, reliable, and easy to maintain. SLA batteries are rechargeable and can last up to five years or more with proper maintenance.

Nickel Cadmium (NiCad) batteries: These batteries are also commonly used in emergency lighting systems. They are known for their long lifespan, high energy density, and resistance to extreme temperatures. NiCad batteries require less maintenance than SLA batteries but are more expensive.

Lithium-Ion (Li-Ion) batteries (also recommended): These batteries are becoming increasingly popular in emergency lighting systems due to their high energy density, lightweight, and long lifespan. They are also more expensive than SLA and NiCad batteries but require less maintenance and can last up to 10 years or more.

Nickel Metal Hydride (NiMH) batteries: These batteries have a high energy density and lightweight, making them an attractive choice for emergency lighting systems. However, they are less common than the other battery types mentioned above due to their higher cost.

Key features of using a UPS include:

Instantaneous switching: The UPS can quickly switch to battery backup power when the main power is interrupted.

Power stability: UPS provides a stable power output.

Reduced power supply: Emergency usage typically requires only 10% of normal illumination, lasting for 90 minutes.

Automatic switching: The UPS automatically switches to battery power when it detects no voltage input, eliminating the need for manual intervention.

Why the Gas Station LED Canopy Light needs to install the emergency battery backup?

The installation of an emergency battery backup for Gas Station LED Canopy Light is primarily based on safety considerations. In the event of a main power failure or outage, the gas station requires emergency lighting to ensure the safety of the work area. As gas stations operate 24/7 and involve many hazardous elements such as flammable materials and high-pressure equipment, emergency lighting is critical during power outages or other emergency situations to safeguard the well-being of staff and customers.

Furthermore, gas stations may face security risks at night, such as theft and robbery. In case of a main power interruption, emergency lighting can provide sufficient illumination, reducing potential security hazards and protecting the safety of customers and employees.

Basic principle and wiring diagram of canopy light with battery backup

Scenario 1: No need for lighting – Switch OFF

When the switch is OFF, the Emergency LED Driver detects that the main power supply has voltage, so both the Emergency LED Driver and the LED driver will not supply power to the luminaire. At the same time, if the battery voltage is sufficient, the Emergency LED Driver will provide a weak charge to the battery. However, if the battery voltage is too low, the Emergency LED Driver will charge the battery. In this case, the luminaire will not operate.

Scenario 2: Regular lighting – Switch ON

When the switch is ON, the main power supply powers the luminaire. The Emergency LED Driver detects that the main power supply has voltage, so it will not supply power to the luminaire. At the same time, if the battery voltage is sufficient, the Emergency LED Driver will provide a weak charge to the battery. If the battery voltage is too low, the Emergency LED Driver will charge the battery. In this case, the luminaire operates at full power.

Scenario 3: Main power failure

When the main power supply fails, regardless of the switch position, as long as the Emergency LED Driver detects that there is no voltage from the main power supply, it will automatically switch to battery power supply. At the same time, the Emergency LED Driver will reduce the output current. In this case, the luminaire operates at reduced power.

Lighting simulation to confirm quantity and wattage

Usually, customers may not be aware of the required quantity and wattage of luminaires, but no worries! We have a solution to help you determine that. According to the International Electrotechnical Commission (IEC) recommendations, the illumination intensity for gas stations should reach 500 lux. This ensures that the work areas at the gas station have sufficient bright lighting, providing a safe and comfortable working environment.

For example, if a customer has a gas station with dimensions of 25 meters in length, 25 meters in width, and 7 meters in height for the refueling area, they would need to install adequately bright luminaires. Based on the Dialux lighting simulation software, we can recommend installing 20 units of ZGSM-GS04-150R luminaires with a power rating of 150 watts each. This configuration ensures that the gas station meets the requirement of 500 lux illuminance intensity.

Emergency power and time toconfirm battery specification

According to the relevant standards, regular public area emergency lighting should reach 10% of the normal lighting level and sustain for 90 minutes. However, you can also request a higher emergency power configuration, such as 30%. Now, let’s try it out. With the emergency scenario set to 30% power, the Dialux simulation displays an illuminance of 187 lux.

In terms of battery configuration, we need to calculate the battery capacity using the formula: Battery Capacity (WH) = Load Power (W) * Operating Time (hours) / Factor (0.9). Applying the formula, we get: Battery Capacity = 150 * 0.3 * 1.5 * 1.9 / 0.9 = 84 WH. Thus, we need to configure a battery with a capacity greater than 84 WH. Considering battery losses and degradation, we typically recommend a 100 WH battery. However, if you don’t need to take these factors into account, a battery with 84 WH capacity would also suffice.
