ILLUMINATING APPARATUS AND METHOD OF CONTROLLING ILLUMINATING APPARATUS
First Claim
1. An illuminating apparatus comprising:
- a first light source configured to output white light, having a first light emitting diode emitting blue light and a first phosphor layer containing blue excited phosphors that emit light when excited by the blue light from the first light emitting diode; and
a second light source configured to output white light, having a second light emitting diode emitting blue light, a second phosphor layer containing blue excited phosphors that emit light when excited by the blue light from the second light emitting diode, and a filter layer configured to partly block blue light that is emitted from the second light emitting diode and is transmitted through the second phosphor layer.

Abstract
An illuminating apparatus 1 includes a first light source 10 to output white light, having a first light emitting diode 11 to emit blue light and a first phosphor layer 12 containing blue excited phosphors M1 that emit light when excited by the blue light from the first light emitting diode 11 and a second light source 20 to output white light, having a second light emitting diode 21 to emit blue light, a second phosphor layer 22 containing blue excited phosphors M2 that emit light when excited by the blue light from the second light emitting diode 21, and a filter layer 23 to partly block blue light that is emitted from the second light emitting diode 21 and is transmitted through the second phosphor layer 22.

11. A method of controlling an illuminating apparatus that includes a first light source of white light having a first light emitting diode to emit blue light and a first phosphor layer containing blue excited phosphors that emit light when excited by the blue light from the first light emitting diode and
a second light source configured to output white light and having a second light emitting diode to emit blue light, a second phosphor layer containing blue excited phosphors that emit light when excited by the blue light from the second light emitting diode, and a filter layer to partly block blue light that is emitted from the second light emitting diode and is transmitted through the second phosphor layer, the method comprising controlling the first and second light sources such that, brightness of the output light from one of the first and second light source is decreased as brightness of the output light from the other is increased.
