Usually, there are many bulbs in a ceiling lamp, when the power is on, all the bulbs are lighting, if the ceiling lamp is working for a long time, it will be energy-consuming. The ceiling lamp control circuit that will be introduced can choose to control the number of the lighting bulb in 8 bulbs, according to the need. The switch circuit consists of the power supply circuit and control circuit, which is shown in the figure. Element selection R1 is adopted with the 1/2W metal film resistor; R2～R12 can be the 1/4W carbon film resistor or metal film resistor.
