Product Specifications

Technical details and manufacturing context for Light Head

Definition
A light head is the primary optical assembly within an adjustable lighting system, containing the light source (such as LED, halogen, or fluorescent bulbs), reflector, lens, and mounting interface. It serves as the functional endpoint that converts electrical energy into controlled visible light output, with adjustable positioning mechanisms allowing precise directional control of illumination. The light head is typically mounted on an arm, track, or pendant, and its orientation can be adjusted via ball joints, swivel arms, or gimbal systems. The housing is usually made of aluminum alloy, polycarbonate, or glass, providing durability and thermal management. The optical system shapes the beam, with beam angles ranging from 15° to 120°, and color temperatures from 2700 K to 6500 K. Rated power varies from 5 W to 50 W, depending on the LED module and driver, and luminous flux ranges from 500 lm to 5000 lm. Input voltage is universal (100–240 V AC), and IP ratings range from IP20 to IP65 for indoor or outdoor use. Operating temperature ranges from -20°C to 50°C. Connection types include screw bases (E26–E40) per IEC 60061. Housing material is often aluminum alloy 6063 per GB/T 5237. Weight varies from 0.3 kg to 2.5 kg. These specifications are typical ranges; verify model-specific values with the manufacturer. The light head is a component, not a complete luminaire, and requires a compatible driver and mounting system. It is used in applications such as track lighting, spotlights, and adjustable task lighting. Proper installation and alignment are essential for optimal performance. Regular inspection for loose connections, lens damage, or overheating is recommended. Failure to maintain may result in reduced light output or premature failure. Always consult the supplier for specific technical data and compliance information.
Working Principle
Electrical current powers the integrated light source within the sealed housing. The reflector and lens assembly then shapes and directs the emitted light beam. Adjustable mounting mechanisms (such as ball joints, swivel arms, or gimbal systems) enable users to precisely orient the light head to achieve optimal illumination angles and coverage patterns. The light source may be an LED module, halogen bulb, or fluorescent tube, each with distinct electrical and thermal characteristics. The housing dissipates heat to maintain safe operating temperatures. The beam angle and intensity are determined by the optical design and the power supplied. Users can adjust the direction to highlight specific areas or objects. The light head is designed to be connected to a compatible power source and control system, such as a dimmer or smart controller, if applicable. Proper installation ensures secure mounting and electrical safety. The working principle is straightforward: electrical energy is converted to light, and the optical system directs it as needed.
