Abstract

DC60 (03/04/43) This light-diffusing device operates on a power supply with variable voltage, requiring only minimal change in charging time. Specifically, a diode bridge (DB) is used as a rectifier to adjust the AC current (Vs) between the primary terminals of a triac (TRC). Resistor R5 and capacitor C1 are connected between the DC supply terminals of the diode bridge (DB) to create a time-constant circuit. A voltage generator circuit is then connected between the DC supply terminals by a fixed resistor (R3) and a variable resistor (VR), and a direct-fit resistor (R4). A transistor (Q1) is in the ON state when the potential difference (V1) across capacitor C1 exceeds the potential difference (V2), which is the potential difference between the base of transistor Q1 and the ammeter of transistor Q2. When transistor Q1 is ON, transistor Q2 also turns ON, charging capacitor C2, and triggering the device. At the gate of the selected Triac TRC (Figure 1), a light-diffusing device is used, which can operate with a power supply that may have slight voltage changes, with only minimal variation in charging time for the lamp. Specifically, a diode bridge (DB) is connected as a rectifier to adjust the AC current (Vs) between the main terminals of the Triac TRC. Resistor R5 is connected to capacitor C1 between the DC supply terminals of the diode bridge (DB) to create a time-constant circuit. A voltage generator circuit is then connected between the DC supply terminals by connecting a fixed resistor (R3) to a variable resistor (VR) and a direct-connected resistor (R4). In the comparison circuit, transistor Q1 is in the ON state when the potential difference V1 across capacitor C1 is higher than the potential difference V2 (the potential difference between the base of transistor Q1 and the ammeter of transistor Q2). When transistor Q1 is ON, transistor Q2 also turns ON, charging capacitor C2, and a trigger signal is sent to the gate of the selected Triac TRC (Figure 1).
