Abstract
The utility model discloses a scheme of the full -color energy -conserving wide voltage display screen module of LED, this scheme is by LED banks (RGB), DC synchronous Rectifier dual output voltage reducing module, IC drive, components such as frame. Through the use that increases DC synchronous Rectifier dual output voltage reducing module, to take to carry out the subregion power supply mode to the banks, the voltage in the control module group uses, reaches the energy -conserving purpose of consumption that reduces the module.
Description
Technical field
The invention that the utility model belongs to electronic technology upgrades, specifically a kind of energy-conservation display screen module of the full-color Width funtion of LED used for LED display industry.
Background technology
Along with LED display widely using commercially, the production of LED display and innovation are also in continuous change, but suitable large of the power consumption of LED display, concept energy-conservation so also just puts forward thereupon, Ye You producer have employed the mode reducing power voltage supply and produces energy-conservation LED module, but because voltage is low, the reason that line loss is large, also the power consumption of fraction is only the reduction of, but display brightness but reduces, also easily produce flower screen, do not reach the request for utilization of user, fundamentally there is not large breakthrough, thus also make power-saving technology also become bottleneck.
Summary of the invention
Instant invention overcomes above-mentioned shortcoming, adopt new method and structure, reach energy-conservation object, led the innovation of LED display in industry, using electricity wisely reduces atmospheric pollution, reaches the effect reducing costs protection of the environment.
Technical scheme of the present invention realizes with under type: the energy-conservation display screen module of the full-color Width funtion of LED, respectively by the lamp group that red, green, blue three lamp is a group, DC synchronous rectification dual output voltage reduction module, IC drives, framework forms, it is characterized in that: adopt DC synchronous rectification dual output voltage reduction module, voltage partition is directly supplied lamp group, and DC synchronous rectification dual output voltage reduction module and module are grouped together; Or adopt independent DC synchronous rectification dual output voltage reduction module to combine with the shortest 0-10 centimetre of spacing, to reduce the line loss of circuit, reach the object of saving electric energy.Power supply 8-36V, after DC synchronous rectification dual output voltage reduction module, converts 2.3-2.5V and 3.3-3.5V to and directly supplies LED group and IC use.To reduce line loss.
Present invention employs the numerical value changing conventional electron voltage, power with the supply voltage of top efficiency.Energy-conservation effect is reached more than comprehensive.

Embodiment
Illustrate further elaboration of the present invention below in conjunction with accompanying drawing.
Fig. 1-Fig. 3 is structural drawing of the present invention, 1: be LED module framework, 2: be DC synchronous rectification dual output voltage reduction module, 3: be LED module lamp district.
Accompanying drawing 4, principle of work of the present invention, which show and convert 2.3-2.5V and 3.3-3.5V to CMOS tube (2) and drive IC (4) power supply by 8-36V through DC synchronous rectification dual output voltage reduction module (1).The CMOS tube of access 2.3-2.5V is powered (3) to R red light; The CMOS tube of access 3.3-3.5V is powered (3) to G green light and the blue lamp of B.Eventually pass drive IC loop (4) and make RGB (red, green, blue lamp) shinny display.
The above, by conventional 5V single service to module, change into 2.3-2.5V and 3.3-3.5V that supply power with double circuit to module, and carry out switched-mode power supply by according to the VF value of RGB lamp (RGB), make it reach energy-conservation object.
On market, LED display module is all adopt 5v to power, wherein need resistance to carry out step-down, drop to the power voltage supply required for VF value of lamp, also have between power supply to module and have circuit different in size, just cause resistance and circuit power consumption is lost, also easily make LED display flower screen.
This programme is by adding DC voltage reduction module, removing resistance, directly presses the VF value power supply of lamp, saves the loss of resistance.This scheme together must be accomplished above the template of module DC voltage reduction module, or adopt independent DC voltage reduction module, with the shortest 0-10 centimetre of spacing combination, to reduce the loss of electric current and voltage, utilize the principle that voltage is high, electric current is little, line loss is few, adopt voltage 8-36v Width funtion to power, because be the use of Width funtion to power, voltage fluctuation does not affect the stability of DC voltage reduction module, and ensure that the brightness uniformity of LED display, solves the problem of LED display flower screen.
Example: not during switched-mode power supply, general outdoor P10 module, one square metre of power consumption is about 700 watts; When adopting switched-mode power supply, general outdoor P10 module, one square metre of electricity consumption about 424 watts; Adopt the highlighted P10 module of outdoor energy-saving, one square metre of actual measurement electricity consumption, less than 100 watts, has saved power consumption greatly.
