Discharge lamps produce light by passing an electric current through an ionized gas or metal vapor, and are known for their high-intensity, energy efficiency, and long life. They are widely used in applications like street lighting, industrial settings, and sports facilities. Common types include fluorescent lamps, high-pressure sodium lamps, and metal halide lamps, which all require control gear to operate.

High-pressure sodium ( HPS) lamps:

Produce a characteristic golden-orange light. They are highly efficient and used for street and area lighting where good colour rendering isn’t critical.

Metal Halide ( MH ) lamps:

Produce a bright, white light with good colour rendering. They are used for a wide range of applications, including sports arenas, factories, and retail spaces.

SON/MH ignitors are crucial electronic components for starting High-Intensity Discharge (HID) lamps, specifically High-Pressure Sodium (SON) and Metal Halide (MH) bulbs, providing the initial high voltage needed for arc ignition, often working with a ballast to deliver a brief, powerful voltage spike for reliable startup, common in streetlights and industrial settings.

How They Work

Ballast Role: The ballast supplies the operating current, but the ignitor provides the starting pulse.

Voltage Spike: The ignitor contains capacitors that charge up and then discharge a short, high-voltage pulse (thousands of volts) across the lamp terminals.

Arc Creation: This intense voltage creates an arc through the gas inside the lamp, initiating light production, especially for SON (sodium vapor) and MH (metal halide) lamps.

Voltage Difference: The ignitor’s pulse voltage is higher than the ballast’s open-circuit voltage, allowing it to start the arc before the ballast takes over.

Key Features & Types

Compatibility: Designed for specific wattage ranges (e.g., 100W-400W, 100W-1800W) and lamp types (SON, MH, HPI, CDM).

Design: Often fully encapsulated for protection and durability, with low internal losses.

Operation: Can be external or integrated into some lamp designs (e.g., SON-T).

Brands: Common manufacturers include Philips (e.g., SN58, SN59), Venture, and Vossloh Schwabe.

Why They’re Used

Reliable Starting: Ensures HID lamps ignite quickly and consistently.

Energy Efficiency: Helps HID lamps operate at peak performance in outdoor, street, and industrial lighting.
