Fig. 1: Night-vision clock circuit LEDs are used in the following two different night lamp circuits. Both of them might be utilized in different ways; one as a night-vision clock, and the other as a TV lamp. Both of the circuits are AC-operated and draw an extremely low amount of electricity. Additionally, these are guarded against oscillations in the mains. The night-vision lamp has twelve LEDs laid out in a circular design similar to that of a wall clock, whilst the TV lamp has twenty-four LEDs placed in a prism-like pattern. The circuit of the night-vision clock is depicted in Figure 1. The voltage is kept at a safe level by the 15V zener diode, the current is lowered to a safe limit by capacitor C1 (0.22uF), which is responsible for reducing the current, and diode D1 is responsible for providing rectified DC, which brings out the characteristic color of white LEDs. The circuit is guarded against a high inrush current by the resistor R2, and it has additional LED protection provided by the resistor R1, which is employed.

Fig. 2: TV lamp circuit Assemble the circuit on a PCB that serves a general function, and then mount the white LEDs (LED1 through LED12) in the circular format of the clock dial, using drilled holes and the appropriate spacing between each LED. In a similar manner, it is possible to place LEDs on another dial of the clock. Figure 2 depicts the circuit for the TV lamp. Watching television in a dimly lit room causes pressure on your eyes. As a result, a lighting of 10-15W is advised. The Ken Schultz circuit is what people commonly refer to as this particular circuit. It is perfectly balanced against surges and voltage spikes and uses a total of 24 white LEDs (LED13 to LED36). Almost no heat is generated by the bulb. Install the white LEDs (LED13 through LED36) in a triangular arrangement before putting the circuit together on a PCB that can be used for a variety of purposes. Next, place it within the TV lamp fitting that was suggested.
