AC light flashing power lamp using SCR

This circuit uses a half cycle of AC power Voltage , for feed give with AC Lamp. The part again a half cycle that go to give with capacitor C1. For build voltage to feed reach a pin G of SCR. When arrive at the dot at firing angle SCR will lead the electric current and let Current at still remain again a half cycle. This change reach at AC lamp make lamp stick can wink. By capacitor appraise 100uF 50V, R1 equal to 2.7K , R2 = 22K , R3 = 3.3K , VR4 = 100K use for fine the speed in winking of Lamp. D1-D2 number HEP R0053 ,SCR number GEC106B1 , which set up on let off the heat with.

Lamp 6 volt flashing by two transistor

This be Lamp Flasher again model apply to Lamp small-sized 6 Volt, by use the principle Amplifier Circuit that use transistor 2 pcs. By have regenerative feedback send pulse of current 60 mS. Which there is tall size arrives at many amp change low voltage lamp. For brightness rate of something flasher , The tall , by don’t go to destroy , Power Lamp the detail is other , see in the circuit adds.

Easy Lamp Flasher to warn

This is lamp flasher circuit. It is use transistor 2 pcs. For the system shows matters for objection which rub encourage give work by the alarm. An officer will take the alarm by pressure the Secretariat of the switch Sa. Which will change a light bulb from the winking to sticking bright is unfinished. a tube is model 6V size entrailses will pull the trend s about 0.3A change transistor Q2. But a resister that is load of transistor Q1 that will limit the trend that change the transistor 6mA very thus. Then transistor that have small-sized can get down.
