Title:
UNIVERSAL LED CHILD-MOTHER LAMP
Document Type and Number:
WIPO Patent Application WO/2015/131383
Kind Code:
A1
Abstract:
Provided is a universal LED child-mother lamp, comprising a child LED lamp (202), a mother LED lamp (201) and a controller for adjusting the luminous flux of the LED lamps, wherein a PWM dimming module (43) is embedded in the controller; and a circuit of the PWM dimming module comprises a first LED drive circuit (431) used for driving the mother LED lamp, a second LED drive circuit (432) used for driving the child LED lamp, a programmable microcontroller (435) connected to the first and second LED drive circuits, and a double-control switch circuit (434) connected to the programmable microcontroller, wherein each of the first and second LED drive circuits is formed by a high-frequency circuit (436) and a DC/DC PWM current amplifier (437). During a high-frequency operation, a stable electric power can be output to the LED lamp to prevent frequent flashes, and because the DC/DC PWM current amplifier (437) overcomes the shortcoming of frequent flashes, a comfortable and soft light and a light modulation function ranging from 0 to 100 percent are provided.
