| titleOfInvention | A light emitting device |
| abstract | A light emitting method for emitting light is characterised in that, a primary light source 23 emitting primary light 22 activates a secondary light source 24 to emit secondary light 25 of a colour different from that of the primary light. A blue led may be used to pump a layer of transitional metal compound, transitional complex metal compound, azo compound, or a variety of fluorescent or phosphate materials to produce a secondary light source. The secondary light produced may be orange, blue or red. The primary and secondary light sources may be mixed, the resulting light 27 may be for example white or violet light. A further layer of coloured material 31 may be used to filter the white light in order to produce light having the same colour as that of the further layer of coloured material. |
