Abstract
The utility model discloses an LED full-color light source, which comprises a one-chip microcomputer, a PWM output circuit, a voltage-current conversion and driving circuit and a three-primary-color LED, wherein the output end of the one-chip microcomputer is connected with the three-primary-color LED by way of the PWM output circuit and the voltage-current conversion and driving circuit in order. The one-chip microcomputer controls ten paths of PWM output circuits, voltage-current conversion and driving circuits and three-primary-color LEDs, controls the color composition of ten paths of three-primary-color LEDs and the variation of ten paths of outputs, and displays color and brightness in dynamic variation.
Description
Technical field
The utility model belongs to the electric component technical field, relates to a kind of LED All colour light source.
Background technology
Nowadays; The LED All colour light source is widely used in bridge, square, building profile, strides the street air corridor, contour of building, road lamp decoration, various illuminated signs board, show window, stage, mansion, hotel are decorated; According to the requirement of city lighting engineering, hope can realize dynamic change in color and brightness.Because LED has semi-conductive physical characteristic, be difficult to adjust brightness and change with voltage control mode, generally all drive with the constant-current source mode, owing to be the cause of constant current, its brightness is non-adjustable.Present LED control device all is single pass simultaneously, can only control paths of LEDs output, and the three-primary color LED limited amount is adorned on every road, can not show more multicolour and color combinations.
The utility model content
The utility model technical problem to be solved provides a kind of LED All colour light source, adopts the color of Single-chip Controlling ten road three-primary color LEDs synthetic, takes PWM to regulate the brightness of every road three-primary color LED simultaneously, can realize the dynamic change of 1,000,000 colors and brightness.
The technical solution of utility model is following:
A kind of LED All colour light source comprises single-chip microcomputer, PWM output circuit, electric current and voltage conversion and drive circuit and three-primary color LED; The output of said single-chip microcomputer is connected three-primary color LED through the PWM output circuit with electric current and voltage conversion and drive circuit successively.
Said single-chip microcomputer is the 98C58 chip.
Comprise ten driving branch roads of forming by PWM output circuit, electric current and voltage conversion and drive circuit and three-primary color LED.
Beneficial effect:
The utility model LED All colour light source adopts the color of Single-chip Controlling ten road three-primary color LEDs synthetic, takes PWM to regulate the brightness of every road three-primary color LED simultaneously, can realize the dynamic change of 1,000,000 colors and brightness.
Below in conjunction with accompanying drawing the utility model is done further to describe in detail.
Description of drawings
Fig. 1 is the utility model LED All colour light source sketch map.
Embodiment
Below will combine accompanying drawing and specific embodiment that the utility model is explained further details:
As shown in Figure 1, the utility model LED All colour light source comprises single-chip microcomputer, PWM output circuit, electric current and voltage conversion and drive circuit and three-primary color LED; The output of said single-chip microcomputer is connected three-primary color LED through the PWM output circuit with electric current and voltage conversion and drive circuit successively.Single-chip microcomputer output pwm control signal is given the PWM output circuit, supplies with three-primary color LED through voltage/current conversion and output driving circuit then, realizes the adjusting to LED brightness.
Single-chip microcomputer can be elected the 98C58 chip as; Have 30 input/output ports; Per 3 input/output ports are used to control the color of one road three-primary color LED; Thereby can control ten road PWM output circuits, electric current and voltage conversion and drive circuit and three-primary color LED, every road connects three input/output ports of single-chip microcomputer.Every road three-primary color LED is a light source, can send 1,000,000 colors, and the Single-chip Controlling color synthesizes the variation with ten tunnel outputs, demonstrates the color and the brightness of dynamic change.
