Patent ID: 8525952

Claim:
An illumination device including a plurality of light source modules, being connected in parallel and driven by a single power voltage, each of the plurality of light source modules comprising: a substrate; at least four red LED devices provided on the substrate; at least four green LED devices provided on the substrate; at least four blue LED devices provided on the substrate; three wiring lines being connected in parallel, including a wiring line having the at least four red LED devices implemented in series; a wiring line having the at least four green LED devices implemented in series; and a wiring line having the at least four blue LED devices implemented in series; at least one zener diode having an operating voltage which varies in accordance with temperature, being provided respectively in at least one of the three wiring lines so as to compensate a voltage variation with temperature of the LED devices provided respectively in the at least one of the three wiring lines under a condition of constant luminance and constant light intensity; and a power supply circuit for driving both of (a) a control signal timing controller circuit mounted on a liquid crystal display device and (b) the plurality of light source modules connected in parallel according to the single power voltage, the power supply circuit being built in the liquid crystal display device.
