Battery-powered fluorescent lamp circuit 1

The circuit described is a battery-powered fluorescent lamp system designed for temporary emergency lighting during power outages. It utilizes a transistor (V7) and a boosting transformer (T) along with an inductive feedback oscillator to generate a high-voltage output. When the circuit is activated, it excites the fluorescent tube (E) to emit light. The circuit employs a 2SD88 type transistor and high-power silicon diodes. It is designed to operate with a 6V, 41h maintenance-free battery, and includes a variable voltage regulator. The transformer should be constructed using a ferrite core with a cross-sectional area of 5mm and wound with high-strength wire of 0.22mm diameter. The circuit is relatively straightforward and does not require extensive trial and error for proper operation. Adjustments to resistor (R) and capacitor (C) values may be necessary to achieve the desired brightness of the fluorescent lamp.

The battery-powered fluorescent lamp circuit serves as an efficient solution for providing illumination during power outages. The core component, a boosting transformer (T), is essential for stepping up the low voltage from the battery to the high voltage required to excite the fluorescent tube (E). The use of an inductive feedback oscillator allows the circuit to maintain a consistent oscillation frequency, ensuring stable operation of the fluorescent lamp.

The transistor (V7), specifically the 2SD88 type, functions as a switching element within the circuit. It controls the flow of current through the transformer, enabling the generation of the necessary high-voltage output. The inclusion of high-power silicon diodes ensures that the circuit can handle the increased current without failure, contributing to the reliability of the system.

For the transformer construction, the choice of a ferrite core with a cross-sectional area of 5mm is critical for optimizing the magnetic coupling and efficiency of the transformer. The winding of the transformer should be done using 0.22mm high-strength wire, which allows for a sufficient number of turns (approximately 20) to achieve the desired inductance. Care must be taken to maintain consistent winding practices to ensure that the inductance values are accurate and that the transformer functions effectively.

The circuit's simplicity facilitates ease of troubleshooting. If the fluorescent lamp does not illuminate, adjustments to the resistor (R) and capacitor (C) values may be necessary to fine-tune the brightness. Additionally, if the lamp fails to start, it could indicate a miswiring of the transformer or an issue with the coil connections. Ensuring that all connections are secure and correctly configured is essential for the circuit's successful operation.

Overall, this battery-powered fluorescent lamp circuit is a practical and efficient design for emergency lighting, combining readily available components with straightforward construction techniques to deliver reliable performance in critical situations.285 is indiscriminately using a battery-powered fluorescent lamp circuit, towns during a power outage use it as a temporary emergency according to the invention.
