Abstract (en)
[origin: EP2660503A1] The lamp has an LED (16) that is arranged at specific distance from a screen (20) so that light from the LED falls on an inner side of screen. A light transmission layer (S1) of screen is set for transmitting light of first wavelength (L1). A color conversion layer (S2) is made of color-converting phosphor material and support material. A light transmission layer (S3) is set for transmitting light of first wavelength and second wavelength (L2) which is larger than first wavelength. The light transmission layers are made of plastic or glass material.
