Abstract

The invention discloses a manual dimmer which mainly consists of an electronic board dimming circuit, wherein the electronic board dimming circuit consists of a timer, a first resistor R1, a second resistor R2, a third resistor R3, a first diode D1, a second diode D2, a first capacitor C1 and a second capacitor C2, one end of the second capacitor C2 is connected with a foot of the timer 6 and the other end of the second capacitor C2 is connected with a ground wire, the second resistor R2 is connected with the negative electrode end of the second diode D2, one end of the first resistor R1 is connected with the second resistor R2, the other end of the first resistor R1 is connected with the circuit power supply end, the third resistor R3 is connected with a positive electrode of the second diode D2, and the other end of the third resistor R3 is connected with a negative electrode of the first diode D1. The manual dimmer has simple structure and low element density and is safe to use. In addition, the manual dimmer has the load short circuit protection function, can realize the short circuit protection function on fluorescent lamps, can prevent the fault of a power supply circuit, and brings great assurance for the normal life of people.

Description

technical field [0001] The invention relates to a dimmer, in particular to an electronic dimmer provided with a circuit board and connection terminals. Background technique [0002] Traditional mechanical and electronic switches only perform simple on-off control when turning on the fluorescent lamp. When the lamp is turned on, the light current has the largest mutation in a short period of time, which can easily cause a strong impact on human vision due to ambient brightness. This phenomenon is particularly prominent when the lights are turned on at night, and this turn-on mode is also one of the main causes of damage to the load bulb. Because the physical characteristic of the fluorescent lamp is that the resistance in the cold state is much smaller than that in the hot state, a large current flows through the bulb when the fluorescent lamp is turned on, and it is easy to cause damage to the bulb. At the same time, this way of adjusting the voltage through metal sheets or...
