Lighting Transformers

Lighting transformers

A lighting transformer is a dedicated distribution transformer designed specifically for lighting systems. Its core function is to convert the high voltage of the power grid (such as 220V/380V) into a safe voltage suitable for lighting loads (such as 36V, 24V, etc.), and to cut off the direct electrical connection between the primary and secondary sides through an isolation structure, providing safe and stable power output for the lighting circuit.

1,Our lighting inverter products utilize high-purity silicon steel cores and oxygen-free copper windings, coupled with a precision winding process to effectively reduce hysteresis and copper losses. No-load losses are as low as below 0.5%, while conversion efficiencies exceed 95%, achieving both energy efficiency and long-term stability. A key highlight lies in the built-in dual safety protection design. The first is a fully isolated transformer structure that completely isolates the direct electrical connection between the primary and secondary sides, significantly reducing the risk of electric shock in the lighting circuit and meeting safety regulations. The second is a triple protection mechanism for overcurrent, overload, and overheating. In the event of an abnormal load or circuit fault, the power supply is quickly cut off to avoid equipment damage and potential safety hazards.

2,Furthermore, our product's housing is molded from cold-rolled steel and treated with an anti-corrosion spray coating, offering excellent dust and moisture resistance, making it suitable for complex environments such as workshops and basements. It also supports a wide voltage input range (160V-250V), ensuring stable output of rated voltage even in fluctuating grid voltages, ensuring uniform, flicker-free brightness for lighting fixtures and extending the life of the light source. From stable commercial lighting to secure power supply in industrial scenarios, this lighting transformer's professional design empowers a wide range of lighting systems, providing an ideal power distribution solution that balances safety, reliability, and affordability.

1. Industrial Production: Suitable for workshops, factories, underground mines, and other areas. These environments are often humid, dusty, and prone to frequent movement. Lighting transformers reduce voltage to a safe 36V or below, preventing equipment leakage and electric shock accidents. They also stabilize output voltage, reducing the impact of grid fluctuations on workshop lighting during the startup of high-power equipment such as machine tools, ensuring stable production lighting.

2. Public and Commercial: These include underground garages, shopping mall showrooms, hospital wards, and subway stations. Enclosed and humid environments like underground garages and subways require isolation to reduce the risk of leakage. Places like shopping malls and hospitals require high lighting stability. Transformers filter grid noise, prevent lamp flicker, and enhance the lighting experience. Hospital ward lighting, in particular, requires a stable power supply to ensure medical staff and patients can rest.

3. Emergency Lighting: These include building emergency passages, fire emergency lighting systems, and temporary outdoor construction lighting. Emergency lighting must operate reliably during power outages and grid anomalies. The lighting transformer's wide input voltage (accommodating fluctuations in emergency power or generator voltage) and overload protection ensure continuous operation in emergency situations and prevent damage to the equipment due to load fluctuations.

4. Special Environments: These include humid bathrooms, commercial kitchens, open-air plazas, and auxiliary lighting for chemical plants exposed to corrosive gases. The high humidity and corrosive environments in these scenarios can easily cause leakage in conventional lighting circuits. The transformer's moisture-proof and corrosion-resistant casing (IP44 or higher) and isolation design ensure its adaptability to harsh environments, while also stabilizing voltage and extending the life of the lamps.

◆ Altitude not exceeding 2,000 meters;

◆ Ambient air temperature -25°C to +40°C, with a 24-hour average not exceeding +35°C;

◆ Relative humidity not exceeding 90% at +25°C and 50% at +40°C;

◆ Location free from severe vibration and impact, and protected from rain or snow;

◆ In a non-explosive medium, free from gases and conductive dust that could corrode metal or damage insulation;

A. Lighting transformers are available in voltage levels of 42, 36, 24, 12, and 6V. Their operating principle is similar to that of ordinary transformers. Structurally, they feature good insulation between the primary and secondary windings, and between the primary winding and ground. Direct electrical contact between the primary and secondary windings is prohibited. This means that tapping the primary winding to achieve a safe voltage is not permitted. Lighting transformers are equipped with a grounding terminal, which must be connected to the ground before use to ensure electrical safety.

B. High Safety: By reducing the voltage, the risk of electric shock is reduced.

Easy Maintenance: The simple structure makes it easy to install and maintain.

Adaptable: The output voltage can be adjusted to meet different lighting needs.
