Product Introduction

This luminaire replaces a white phosphor source and colored sleeve with LEDs that emit principally in the amber region. The controlled spectrum is used where photoresists, films or light-sensitive materials must be handled under reduced blue and near-UV energy. The fixture retains the same gasketed white housing and smooth optical face used for general cleanroom lighting, while amber lenses or indicators clearly distinguish the circuit.

Key Features

Native amber emitters avoid relying only on a fading external filter.

The narrow spectrum reduces unwanted short-wavelength energy at the work surface.

A sealed optical chamber protects LEDs and wiring from room cleaning.

Amber identification makes the protected lighting circuit visually obvious.

Dimming allows the illuminance to be matched to the sensitivity of the process.

Customer Product Concerns

A yellow-looking lamp is not necessarily spectrally suitable; emitted blue energy and filter aging must be considered separately from appearance.

A white LED behind a yellow cover still leaks short-wavelength energy.Native amber emitters minimize blue content at the source.

Colored plastic filters fade after heat and cleaning exposure.The spectral function comes from the LED source rather than only from the cover tint.

Operators accidentally switch on ordinary white lights.Distinct amber fixtures and separately identified controls differentiate the protected circuit.

Excessive intensity can still affect a highly sensitive process.Dimming and layout selection tune illuminance as well as wavelength.

Typical Applications
