Detailed Description
The utility model is described in further detail below with reference to fig. 2-3.
The embodiment of the utility model discloses a down lamp induction electric discharge circuit. Referring to fig. 2, the down lamp induction electric discharge circuit includes a power supply, a down lamp string is connected to a current output end of the power supply, and an induction current consumption load is connected between a current input end and a current output end of the down lamp string; the electric input end of the down lamp is connected with a grounded capacitor discharge assembly; the current output end of the down lamp string is connected with a controlled switch component, the controlled switch component is used for controlling whether the power supply supplies power to the down lamp string or not, and the current output end of the controlled switch component is connected with the current input end of the power supply.
In implementation, on the one hand, realize the discharge of some induced currents through the induced current consumption load in order to consume the induced current's that produces in the down lamp mode, another convenient mode that leads into the earth with induced current through the electric capacity discharge assembly realizes the discharge of surplus induced current to make induced current be difficult to through down lamp string, and then after closing the down lamp, induced current no longer makes down lamp string slightly light, so is convenient for realize the thoroughly of down lamp, thereby promotes the use experience after the remote control down lamp closes.
Specifically, referring to fig. 3, the power supply is electrically connected to a power supply driver, and the power supply driver is used for converting the voltage and the current input to the down lamp string by the power supply; the down lamp string comprises a cold lamp string LED1 and a warm lamp string LED2 which are connected to the current output end of the power driver, and the current input ends of the cold lamp string LED1 and the warm lamp string LED2 are electrically connected with the current output end of the power driver. The induction current consumption load comprises a first load R1 connected between the current input end and the current output end of the cold color light string LED1, and further comprises a second load R2 connected between the current input end and the current output end of the warm color light string LED2, wherein the first load R1 is arranged in parallel with the cold color light string LED1, and the second load R2 is arranged in parallel with the warm color light string LED 2. The controlled switch assembly comprises a first control switch device M1 connected in series with the current output end of the cold color light string LED1, the current output end of the first control switch device M1 is connected with the current input end of the power driver, and the first control switch device M1 is used for controlling whether the power supply is open or not with the cold color light string LED 1; the controlled switch assembly further comprises a second control switch device M2 connected in series with the current output end of the warm color light string LED2, the current output end of the second control switch device M2 is connected with the current input end of the power driver, and the second control switch device M2 is used for controlling whether the power supply is opened or not with the warm color light string LED 2.
In this embodiment, the first load R1 and the second load R2 are preferably resistors, and the resistance of the resistors is smaller than that of the down lamp string; the cold color light string LED1 is a cold color light string preferentially, and the warm color light string LED2 is a warm color light string preferentially.
In implementation, if the down lamp needs to be turned off, the first control switch device M1 is manually controlled to make the power supply and the cold light string LED1 in an open state, and the second control switch device M2 is manually controlled to make the power supply and the warm light string LED2 in an open state, so that the power supply does not normally supply power to the cold light string LED1 and the warm light string LED 2; at this time, the power supply and the power supply driver are in a power-on state, and the current input ends of the cold color light string LED1 and the warm color light string LED2 are in a connection state, so that the current input ends of the cold color light string LED1 and the warm color light string LED2 have high potential; although the first control switch device M1 is no longer connected to the current input ends of the cold string LED1 and the power driver, the second control switch device M2 is no longer connected to the current input ends of the warm string LED2 and the power driver, the metal structure including the metal lamp cover and the metal radiator in the down lamp is close to the cold string LED1 and the warm string LED2, so that low potential is induced at the current output ends of the cold string LED1 and the warm string LED2, thus potential difference is induced at both ends of the cold string LED1 and both ends of the warm string LED2, induced current is induced in the cold string LED1 and the warm string LED2 due to the potential difference, and the cold string LED1 and the warm string LED2 still emit light slightly under the condition that both ends are in an open state with the power supply due to the existence of the induced current.
However, in the present embodiment, since the first load R1 is connected in parallel to the cold string LED1, and the resistance of the first load R1 is lower than that of the cold string LED1, the induced current induced by the potential difference at two ends of the cold string LED1 mainly passes through the first load R1 and is consumed by the first load R1, so that even though a small portion of the induced current passes through the cold string LED1, it is difficult to drive the cold string LED1, so that the cold string LED1 is not slightly lighted when the first control switch device M1 is in the off state; similarly, since the second load R2 is connected in parallel to the warm string LED2, and the resistance of the second load R2 is lower than that of the warm string LED2, the induced current induced by the potential difference at two ends of the warm string LED2 mainly passes through the second load R2 and is consumed by the second load R2, and even if the remaining small part passes through the warm string LED2, it is difficult to light the warm string LED2, so that the warm string LED2 is not slightly lighted when the second control switch device M2 is in the off state.
With continued reference to fig. 2, the capacitor discharge assembly specifically includes a discharge capacitor C connected to the current input of the cold string LED1 and the current input of the warm string LED2, and a discharge capacitor J connected in series to ground.
In order to thoroughly avoid small induction current flowing through the cold string LED1 and the warm string LED2, the resistance between the discharge flashlight and the discharge capacitor J and the ground is far lower than that of the cold string LED1 or the warm string LED2, so that small induction current flowing through the cold string LED1 or the warm string LED2 originally flows to the ground through the discharge capacitor C and the discharge capacitor J, thereby further facilitating the prevention of the induction current from slightly lighting the cold string LED1 and the warm string LED2, and thoroughly discharging the induction current, thereby thoroughly turning off the down lamp and avoiding the light.
