Abstract
Various examples of a lighting device, backlight module and illumination module are described. A lighting device includes a carrier component, an LED chip, a thermistor, and a plurality of metal wires. The carrier component includes a plurality of electrodes. The LED chip and the thermistor are disposed on the carrier component and electrically coupled to each other. The plurality of metal wires form a circuit with the plurality of electrodes, the LED chip, and the thermistor. The thermistor has dimensions in chip-level scale when viewed from the top of the lighting device. A backlight module includes the aforementioned lighting device. An illumination module includes the aforementioned lighting device and a driver which is electrically coupled to the lighting device.
