Description

A kind of color selector LED light source regulating system
Technical field
The utility model is related to color selector technical field more particularly to a kind of color selector LED light source regulating systems
Background technology
At present, as people's living standard gradually steps up, color selector is appearing in people at the moment often.In traditional color selector Color sorting different material, for different material colour gradings, it is necessary to different background luminances.The many color selectors in market are all at present With motor background board is driven to adjust angle, background light source brightness is adjusted so as to reach to change background light source irradiating angle with this Purpose.But motor is rotated there are motor rotation slowly, precision is not high, and it is not in place to use very easy rotational angle It happens.Simultaneously in big type, since the long such background board of fuselage length is also long.Long background board meeting Since intermediate sagging occurs in self gravitation, while long background light also results in needs more high torque motor to support, Cost is excessively high.The utility model proposes color selector LED light source regulating system, not needing rotate background board, it is only necessary to one Fixed background board, and application method will not increase use cost, only need to simply transform the Switching Power Supply of background light i.e. The purpose of voltage can be adjusted.
Utility model content
The purpose of this utility model is to provide a kind of color selector LED light source regulating system, to solve above-mentioned background technology The problem of middle proposition.
To achieve the above object, the utility model provides following technical solution:
A kind of color selector LED light source regulating system, including host computer, microcontroller, digital regulation resistance, LED light, switch electricity Source.
The host computer adjusts voltage instruction for sending, and receives the voltage value feedback of microcontroller passback, described upper Machine is connected by serial ports 232 with microcontroller, and the microcontroller is connected with digital regulation resistance, and the Switching Power Supply passes through conducting wire and list Piece machine connects, and resistance is in series between Switching Power Supply and microcontroller.
The Switching Power Supply is connected by conducting wire with digital regulation resistance, LED light, the ground wire of Switching Power Supply and digital current potential The ground wire of device, the ground wire of microcontroller need to be maintained on same ground level.
Further, the digital regulation resistance is equipped with two groups, respectively coarse tune digital potentiometer, fine tuning digital regulation resistance, The coarse tune digital potentiometer is connected with fine tuning digital regulation resistance.
Further, the adjustable range of the coarse tune digital potentiometer is five to ten times of fine tuning potentiometer.
Further, the microcontroller is connected by SPI or I2C with digital regulation resistance.
Further, the resistance connected between the Switching Power Supply and microcontroller is high-accuracy resistance.
The beneficial effects of the utility model are:It is more traditional there is provided the control system that can automatically adjust LED light brightness The method for adjusting LED light source irradiating angle, it is more intelligent, and can be with intensifier service life, by adjusting number electricity The gear of position device achievees the purpose that the input voltage for adjusting LED light, adjusts more accurate, color sorting quality higher.
