Abstract
A luminous device includes a luminous module. The luminous module includes a plurality of LED chips, a driving chip and a package body. The driving chip is configured to selectively drive the LED chips to emit light. The driving chip includes a power pad, a plurality of LED pads corresponding to the plurality of LED chips respectively and a ground pad. The driving chip receives a power signal having a selecting signal and a luminous signal by the power pin, and determines the LED chips to emit light according to the luminous signal or not based on the selecting signal. The luminous device uses the power signal of selecting the LED chip as the driving power for driving the LED chips to emit light in the same time. The luminous device not only reduces the volume, but also saves the cost.
