ABSTRACT:
An improved brightness control apparatus of a light bulb module replaces a portion of a conventional light bulb module brightness control apparatus by a signal receiving circuit, an amplification circuit and a failure protection circuit to maintain an even brightness of light emitted by each light bulb of the light bulb module of a lamp, so that the brightness of the light bulbs in the light bulb module will not be too dark or even not lit. The signal receiving circuit is provided for connecting an external remote control device for controlling the light bulb module. If the control circuit fails, the failure protection device can maintain a temporary illumination and an overall aesthetic look of the lamp. When the control circuit is operated normally, the total power consumption of the light bulbs of the light bulb module can comply with the normal rated standard of illumination equipments.
