Abstract

A reading light for a vehicle, in particular for fitting above a vehicle seat of a vehicle, such as an airplane, comprises at least one LED emitting white light, and a reflector and/or a light cover, the reflector and/or the light cover being provided with a coating that absorbs or reduces the intensity of the light of the at least one LED whose wavelength is less than a predefinable wavelength value.

Claims

1. A reading light for a vehicle, in particular for fitting above a vehicle seat of a vehicle, such as an airplane, comprising

at least one LED emitting white light, and

a reflector and/or a light cover,

the reflector and/or the light cover being provided with a coating that absorbs or reduces the intensity of the light of the at least one LED whose wavelength is less than a predefinable wavelength value.

2. The reading light of claim 1, wherein the at least one LED emits light at least in the wavelength range between about 380 nm to about 780 nm, and wherein the coating absorbs or reduces the intensity of light in the wavelength range below about 500 nm.
