Also require that lighting device being capable of modulated light.In the prior art, it is necessary to right in the indicative lighting device of such as some equipment
The light source that sign is illuminated, especially LED are dimmed, for example, control it to be turned on or off.Because this instruction
Property lighting device often in the narrower region in space of equipment, therefore generally by the control unit in equipment,
The conventional single-chip microcomputers such as the common single-chip microcomputer of such as in the market, such as the ATtiny25 of ATMEL, the PIC16F1826 of MICROCHIP
LED is controlled, the space shared by indicative lighting device thus can be as far as possible reduced.
Figure 1 illustrates prior art in scheme in, be lower margin as the lower left corner of the single-chip microcomputer of control unit 1, it is right
Upper angle is supply pin VCC.In this scenario, by common I/O mouthfuls of the lower right corner come output control signal, to drive field-effect
Transistor Q1 controls LED light emitting diode D1 light on and off.But because I/O mouthfuls of common driving force is not very big, if LED sends out
Optical diode D1 needs high current (representative value is more than 10mA), then common I/O can be not competent, so needing extra increase field
Effect transistor Q1 come be realize.Additionally, also needing in the circuit using multiple resistance R1, R2, this also occupies certain
Space.Meanwhile, in the technical scheme, in order to control LED, it is necessary to additionally take one I/O mouthfuls, this is also limited to a certain extent
The range of application of single-chip microcomputer is made.
The content of the invention
To solve the above problems, the present invention proposes a kind of Dimmable lighting component.Dimmable lighting group of the invention
Part can apply the relatively large luminescence unit of power, and device of its application is relatively fewer, and the space of occupancy is also relatively
It is small, and will not also take the resource of control unit.Additionally, the present invention also proposes a kind of Dimmable lighting with the above-mentioned type
The indicative lighting device of component.
First purpose of the invention is achieved in by a kind of Dimmable lighting component, i.e. Dimmable lighting component tool
There is control unit and be connected to the luminescence unit of control unit, wherein Dimmable lighting component also has voltage regulation unit, control

The conventional single-chip microcomputer such as PIC16F1826.Since it is designed that the control unit of single-chip microcomputer is in parallel with luminescence unit, and single-chip microcomputer
Supply pin is connected directly to voltage regulation unit, then luminescence unit is also connected to the supply pin of single-chip microcomputer.In actual operation
In, the single-chip microcomputer in parallel with luminescence unit can produce shunting action to the electric current from power supply, so as to control the light of luminescence unit
Output intensity.Further, since luminescence unit is connected directly to the supply pin of single-chip microcomputer, therefore need not additionally take single-chip microcomputer
One I/O mouthfuls, I/O mouthfuls that this is saved can be used for other purposes.In addition, the supply pin of single-chip microcomputer has stronger driving force,
Therefore it can drive the luminescence unit for needing relatively large electric current.
Preferably, luminescence unit is made up of at least one LED light emitting diodes.Can be with design of the invention
Multiple LED light emitting diodes are concatenated as needed, so as to obtain the instruction pattern or configured information of various configuration.
It may further be preferable that by activating the D/A switch function or sleep mode of microcontroller to from power supply
Electric current shunted.In the microcontroller can be by software activation above-mentioned functions, naturally it is also possible to activate microcontroller
Other inherent functions.When these functions are activated, the power consumption of microcontroller can be increased, so as to reduce to luminescence unit
Electric current is exported, so as to reach shunting purpose.
It is proposed, according to the invention, that power supply is dc source.LED light emitting diodes are driven by the dc source.
In design of the invention, voltage regulation unit is adjusted including at least one pair of voltage from power supply
Diode.Diode is down to the level of the rated operational voltage of microcontroller by voltage, so that it is guaranteed that microcontroller is normal
Work.
Another object of the present invention passes through a kind of indicative lighting device of the Dimmable lighting component with the above-mentioned type
Realize.Lighting device of the invention has less device, takes less space, with low cost, and it can be carried
For relatively large light output intensity.
