Problems solved by technology

[0002] Flashlight is a common electronic lamp in daily life. It can emit flashing lights. It is often used for road construction, safety warning, stage lights and indicator arrows. As a safety warning light, it can greatly reduce the probability of accidents. As a stage light It can greatly increase the atmosphere of the stage. At present, most common flashlights are composed of oscillators combined with switching elements. This structure not only has many circuit components, but also has a short service life and is easy to be damaged.

Abstract

The invention discloses a double-LED flasher circuit. The double-LED flasher circuit comprises a resistor R1, a capacitor C1, a triode VT1, a triode VT2, a resistor R6 and an LED 1, wherein one end of the resistor R1 is connected with a control signal Vi and the resistor R2, the other end of the resistor R1 is connected with a base electrode of the triode VT1, a collector of the triode VT1 is connected with a base electrode of a triode VT4, an emitting electrode of the triode VT4 is connected with a power source VCC, a collector of the triode VT4 is connected with the LED 1, and the other end of the resistor R2 is connected with a base electrode of the triode VT2. The double-LED flasher circuit adopting triode control is capable of controlling alternate flickering of high level and low level of control signals, and is quite simple in circuit structure and wide in application range.

Description

technical field [0001] The invention relates to an LED circuit, in particular to a double LED flashing circuit. Background technique [0002] Flashlight is a common electronic lamp in daily life. It can emit flashing lights. It is often used for road construction, safety warning, stage lights and indicator arrows. As a safety warning light, it can greatly reduce the probability of accidents. As a stage light It can greatly increase the atmosphere of the stage. At present, most common flashlights are composed of oscillators combined with switching elements. This structure not only has many circuit components, but also has a short service life and is easy to be damaged. The invention provides a double LED flashing circuit controlled by triodes, which can alternately flash according to the high and low levels of the control signal, has a very simple circuit structure and is widely used. Contents of the invention [0003] The purpose of the present invention is to provide a d...
