Tungsten filament lamp is an incandescent lamp made with tungsten filament as the filament. Tungsten filament lamps can generate continuous spectra for use in the visible spectral range of 400-780nm. Used as a visible light source in a spectrophotometer. Its spectral effective region can extend to 3 μ m. Therefore, it is also used as a light source in the near-infrared region
Lamp testing items:
Electrical performance parameters: working voltage, working current, power, power factor, lamp safety level, insulation resistance, etc.
Optical parameters: light intensity (light intensity distribution curve, equivalent light intensity curve), light flux (total light flux, effective light flux, etc.), etc.
Illuminance: (light intensity distribution, equivalent light intensity curve), light source (number of light sources, light source model, etc.), color temperature Luminaire luminous angle, etc.
Structure and appearance: shell structure material, type of lamp, weight of lamp, label of lamp, protection level of lamp, etc.
