Abstract
A light emitting device including a lighting unit and a conversion material is disclosed. The conversion material is configured to convert a part of the invisible light emitted from the lighting unit into a visible light, which indicates that the lighting unit is in operation. The spectral energy of visible light is less than 20% of the spectral energy measured within a wavelength range of 200 nm to 380 nm.
