Ex-proof Fluorescent Luminaires

Ex-proof fluorescent luminaires are special luminaires designed for use in explosive atmospheres. These luminaires can be used in hazardous areas where flammable gases, vapors, liquids, or dusts are present.

Ex-proof fluorescent luminaires vary according to protection classes. The most common protection classes are known as Ex d, Ex e, and Ex n. Protaş products are of Ex d type flameproof.

Luminaires in the Ex d protection class are covered with explosion-proof enclosures. These enclosures prevent gases and vapors that can cause explosions from entering and protect the internal parts of the luminaire.

Luminaires in the Ex e protection class are made using comprehensive sealing and gasket techniques. Thus, the luminaire prevents the internal parts from contacting flammable environments.

Luminaires in the Ex n protection class are made of high-resistance materials that protect electrical parts without using protective shells or enclosures against explosions.

Some features of Ex-proof fluorescent luminaires are as follows:

• They can operate over a wide temperature range (-20°C to +60°C).
• They have a high protection level (IP65 and above).
• They provide easy installation and maintenance.
• They are long-lasting.
• They are energy-efficient with low power consumption.
• Various lengths, powers, and lamp types are available.

Ex-proof fluorescent luminaires are commonly used in industrial facilities such as petroleum refineries, chemical plants, mines, ships, furnaces, storage tanks, and other explosive environments.

If you need more detailed information about ex-proof fluorescent luminaires, it is recommended to contact an expert electrical engineer or industrial lighting specialist.

Production Principle

The part that causes the arc in the normal operation of fluorescent lamps is the STARTER. Like incandescent filament lamps, the surface temperature of the tube is also an issue. In Protaş fluorescent lamps, the starter is placed in a special protective and pressure- and impact-resistant special tube inside the fluorescent tube, thus eliminating the surface temperature problem. Protaş ex-proof fluorescent lamps have chosen high quality for this special production product.

Protaş fluorescent lamps place the starter and fluorescent tube separately inside a d-type protected enclosure. Recently, since a capacitor is also requested to correct the power factor (cos α), the starter and capacitor are manufactured together inside the same d-type enclosure. The Protaş fluorescent tube is placed inside a specially manufactured glass tube resistant to pressure. This tube has been tested and certified to be pressure-resistant. Being in the form of a round tube, it is easier to manufacture compared to a glass globe and is more resistant to pressure and impact. D-type protected fluorescent luminaires are more common in Turkey.
