ILLUMINATION DEVICE AND LIQUID-CRYSTAL DISPLAY DEVICE Russian patent published in 2011 - IPC H05B37/02 H01L27/15 G02F1/133 

FIELD: physics.

SUBSTANCE: light-emitting diode (LED) assembly 20, LED former, comprising a FET 42 (field-effect transistor, current regulating transistor, excitation section) and a thermistor 30 lie on a substrate 10. A plurality of such LED assemblies 20 lie on a substrate 10, whereby an area 50 and area 60, each defined by vertices corresponding to LED assemblies 20, are formed on the substrate 10. The thermistor 30 lies in area 50, and the FET 42 lies on the area 60, which lies outside the area 50. The thermistor 30 detects temperature on area 50. Such a configuration enables the thermistor 30 to detect, in accordance with temperature in area 50, temperature due to heat transferred from the LED assemblies 20, without being affected by heat generated by the FET 42.

EFFECT: efficient temperature correction in order to stabilise colour temperature and brightness.
