Problems solved by technology

[0003] In order to improve the output stability of the light-emitting diode, a large capacitor is mounted on the output stage of the driver circuit of the light-emitting diode. If the output is in a low-dimming (low current) state, the LED will light up because the capacitor charging time is too long It takes too long to start up, causing users to misjudge whether the LED light is working properly
The main reason for this problem is the working voltage characteristics of the LED. When the capacitor charging voltage has not reached the working voltage of the LED, the LED light has been over-charged but the voltage is insufficient and still stays in the cut-off area of ​​the LED light, resulting in the LED not being able to light up.

Abstract

The invention provides a quick start system without voltage detection, which includes a drive circuit, a current control switch, and a controller. The drive circuit feeds current to the load and the filter capacitor set corresponding to the load. The current control switch is connected to the output of the driving circuit, and the loop is opened and closed through the received signal to control the input power of the load and the filter capacitor. The controller is connected to the current control switch. The controller records the relevant parameters of the previous capacitor discharge to obtain the equivalent charging period for reaching the LED operating voltage parameter, and sends a control signal to the current according to the equivalent charging period. A switch is controlled to switch the load and the input power of the filter capacitor.

Description

technical field [0001] The present invention relates to a quick-start system for LEDs, in particular to a quick-start system without voltage detection. Background technique [0002] With the development of technology and the breakthrough of white light LED technology, light-emitting diodes have been widely used in various household lighting devices. Since LED lamp itself is a high-efficiency lighting source, it is gradually replacing traditional incandescent lamps and fluorescent lamps in recent years and has become the mainstream of the lighting market. [0003] In order to improve the output stability of the light-emitting diode, a large capacitor is mounted on the output stage of the current light-emitting diode drive circuit. If the output is in a low-dimming (low current) state, the LED will turn on because the capacitor charging time is too long It takes too long to start, causing users to misjudge whether the LED light is working properly. The main cause of this pro...
