Abstract
A light emitting diode (LED) converter and device are provided. The LED converter includes: a controller which is configured to control a power supply for a LED, and a push button which is configured to couple with the controller, wherein the push button is isolated from the controller by at least one safety capacitor between the push button and the controller. Therefore, the push button can be isolated from the controller to improve safety while with a simple structure and a low cost.
Claims (10)
1. A light emitting diode (LED) converter, comprising: a controller which is configured to control a power supply for a light emi tting diode (LED) , and a push button which is configured to couple with the controller, wherein the push button is isolated from the controller by at least one s afety capacitor between the push button and the controller.
2. The converter according to claim 1, wherein the converter further comprises: a resistance which is configured to connect with the controller; wherein a first safety capacitor and the resistance are configured betwee n the controller and the push button.
3. The converter according to claim 2, wherein the first safety capacitor is a Y-Cap.
4. The converter according to claim 2, wherein the push button is supplied by a voltage, and a second safety capacitor is configured between the voltage and the p ush button.
5. The converter according to claim 4, wherein the second safety capacitor is a Y-Cap.
6. The converter according to claim 4, wherein when the push button is pushed to be on, a current is picked up to the controller through the resistance; when the push button is pushed to be off, there is not current on the resistance.
7. The converter according to claim 2, wherein the push button is supplied by a pulse width modulation (PWM) signal, and a second safety capacitor is configured between the pulse width modul ation (PWM) signal and the push button.
8. The converter according to claim 7, wherein the second safety capacitor is a Y-Cap.
9. The converter according to claim 7, wherein when the push button is pushed to be on, a signal is picked up to the controller through the resistance; when the push button is pushed to be off, there is not signal on the resistance.
10. A light emitting diode (LED) device, comprising: a transformer having a primary side and a secondary side, wherein the secondary side is connected to a light emitting diode (LED) ; a switching element which is configured to connect to the primary side and control a power supply for the light emitting diode; a controller which is configured to control the switching element, and a push button which is configured to couple with the controller, wherein the push button is isolated from the controller by at least one s afety capacitor between the push button and the controller.
