Problems solved by technology

However, since the driving capability of the ordinary I / O port is not very large, if the LED light-emitting diode D1 requires a large current (typically greater than 10mA), the ordinary I / O is not competent, so an additional field effect transistor Q1 is required to realize
In addition, multiple resistors R1, R2 need to be used in this circuit, which also takes up a certain amount of space
At the same time, in this technical solution, in order to control the LED, an additional I / O port needs to be occupied, which also limits the application range of the single-chip microcomputer to a certain extent.

Abstract

The invention relates to a dimmable lighting module provided with a control unit, a light-emitting unit connected to the control unit and a voltage regulation unit. On one hand, the control unit and the voltage regulation unit are serially connected between a power source (Vcc) and the ground (GND), and on the other hand, the control unit and the light-emitting unit are parallelly connected between the ground (GND) and the voltage regulation unit. The control unit is used for shunting current of the power source (Vcc) so as to control light output intensity of the light-emitting unit. Besides, the invention further relates to a directive lighting device with the dimmable lighting module.

Description

technical field [0001] The present invention relates to a dimmable lighting assembly for an indicator lighting device. Furthermore, the present invention also relates to an indicator lighting device having a dimmable lighting assembly of the above-mentioned type. Background technique [0002] With the widespread introduction of LED lighting technology, people have higher and higher requirements for lighting devices, such as requiring lighting devices to have higher light efficiency and longer life, and to obtain different lighting in order to apply in different environments effect, it is also required that the lighting device can be dimmed. In the prior art, for example, in an indicator lighting device of some equipment, it is necessary to adjust the light source for illuminating the indicator sign, especially the LED, for example, to control its turning on or off. Because this kind of indicative lighting device is often installed in an area where the space of the equipmen...
