ABSTRACT:
A brightness control device for a light bulb module utilizes a microcontroller equipped with a first control circuit, a second control circuit, a third control circuit, and a fourth control circuit to maintain an even luminance of each light bulb in the light bulb module of a lighting fixture to avoid the situation that one of the light bulbs is darker than others or even fails to illuminate. Therefore, the lighting artistry of the whole lighting fixture can be maintained, and the total consumed power of all the light bulbs in the light bulb module is capable of meeting the requirement of the maximum rated power consumption of the illumination equipment under the local ordinance.
