LIGHT SOURCE CONTROL DEVICE, ILLUMINATON DEVICE, AND LIQUID CRYSTAL DISPLAY DEVICE
Abstract:
A light emission device capable of holding a uniform color in various environments. A light source control device has a light detection device for detecting emission brightness of light sources that emit different colors and controlling emission brightness of at least one light source of the light sources based on the detection result of the light detection device. A through-hole is formed in a reflection member for reflecting light emitted from the light source, and the reflection is in a predetermined direction. The light detection device is provided across the reflection member from the light source, and the light propagation member is provided at the through-hole.
