FIELD: physics.SUBSTANCE: light-emitting device (100) according to the invention has a light emitter (101) situated on a substrate (102) and a reflecting optical housing (103, 108) surrounding said light emitter (101). The space (106) between said reflecting optical housing (103, 108) and said light emitter (101) is filled with a suspension of reflecting material (104). The light-emitting device further includes at least one channel (105) which is suitable for use of said reflecting material (104). Also disclosed is a method of making the light-emitting device described above.EFFECT: improved luminous efficacy, simple technique of making the light-emitting device, low consumption of material of making the light-emitting device.10 cl, 10 dwg |
