Common terminology for tungsten halogen lamps

1. Lamp Axis

The lamp axis refers to the central line passing through the geometric center of the light source. It is a key parameter in determining the direction and alignment of the light emitted by the bulb.

2. Initial Photoelectric Parameters

These are the optical and electrical values measured at the end of the bulb's aging process. They typically include color temperature, luminous flux, and power consumption, which provide essential information about the bulb's performance and efficiency.

3. Height of the Light Center

This term describes the vertical distance between the effective geometric centerline of the filament and the contact point at the bottom of the lamp base. It plays an important role in ensuring proper installation and optimal light distribution.

4. Cylindrical Tungsten Halogen Bulb

A cylindrical halogen bulb that is designed with a single-ended structure. This type of bulb is commonly used in applications where space is limited, and a compact design is required.

5. Cold Reflection Directional Lighting Tungsten Halogen Bulb

This type of tungsten halogen lamp incorporates a multi-plane dielectric film mirror to reflect light more efficiently, reducing heat emission while directing the light precisely. When combined with a lens, it becomes a closed cold reflection directional lighting bulb, ideal for focused illumination in various lighting systems.
