Abstract

The utility model relates to an intelligence grading control source adopts the drive IC of the adjustable luminance of ordinary tap, like BYD electronic BF1030, add other a conventional constant current drive chip again, like brilliant feng ming source BP2832A, two circuit are worked respectively, and conventional IC works always, adjust the electric current of exporting all the way through conventional switching regulator IC internal circuit, reach the regulation of luminance, finally accomplish the effect of colour mixture. Compare with the scheme of present existence, this utility model can greatly reduce the material cost, including saving rectification filter circuit, the improvement of integrated level, the very big circuit volume that has reduced, can be more nimble use in the scene of difference, and can reach the effect of multiple colour mixture, when the switch button, the mixing of colors IC divide the electric current that four segment outputs are different, just can thoughtlessly go out the photochromic of four kinds of styles, the effect of colour mixture has greatly been richened, the effect of adjusting lamps and lanterns luminance of also playing when inserting two tunnel the same light sources.

Description

A kind of intelligent distribution controls power supply

Technical field

The utility model design field of intelligent control, specifically a kind of intelligent distribution controls power supply.

Background technology

Along with the development of technology, people have had more and more higher requirement to life kind, very high requirement be there has also been to the requirement of light, such as the light fixture of warm colour temperature is needed to be that in room, sensation is warm in the winter of cold, in the summer of sweltering heat, need again the light fixture of cool colour temperature to feel nice and cool to the sensation of people, need usually again the neutral light close to sunlight, this just needs a kind of light fixture of adjustable color temperature.

Along with the pollution of environment and the minimizing in arable land, the technical development of artificial growth is also advanced by leaps and bounds, artificial growth is most important is exactly allow plant carry out photosynthesis greatly, and plant carries out photosynthesis most important is exactly illumination, research shows that most important is exactly present extensively product LED blue light and ruddiness, but ruddiness promotes the quick growth of plant leaf, blue light promotes the growth of plant stem, so different plants just needs different red blue light proportionings.

Present fresh lamp on the market generally adopts the light of red white two kinds of colors to allot the use of various applicable different occasion, such as sell meat shelves and just need more redness, vegetables vegetables and fruits need neutrality a bit, seafood burns white some light of cured needs, and various different demand causes need of production to output various different circuit board to arrange different colours proportioning.

Very large Cost Problems is there is in the colour temperature occurred on the market now above regulating, with a switch-segment switch add 2 independently power supply light cold white or warm white LED lamp pearl respectively, and regulate color temperature mode very single, a complete bright warm Bai Dengquan of cold white lamp is only had to go out the cold light being, the complete bright cold warm white entirely gone out in vain of warm white lamp is exactly the entirely bright neutral light of positive Bai Nuanbai lamp three kinds of colour temperatures at one.

Summary of the invention

For the deficiency existed now, provide a kind of integrated, cost is low, the intelligent luminous intensity distribution power supply of environmental protection and energy saving.There is multistage adjustment, as the red blue proportioning lamp application of colour temperature, plant lamp.

The utility model comprises rectification circuit, input filter circuit, high accuracy adjusting and voltage-reduction switch dimming LED (Light Emitting Diode) current constant control chip, voltage-dropping type LED constant current driving chip, output filter circuit, it is characterized in that, by rectification circuit by voltage commutation, again after filtering, enter adjusting and voltage-reduction switch dimming LED (Light Emitting Diode) current constant control chip and voltage-dropping type LED constant current driving electrical chip respectively, be transformed into the output of different electric current to control the different light fixture of two-way, the output of LED constant current driving chip regulates different electric currents to export by the number of times of switch, reaches the effect of colour mixture.

The utility model adopts following technology to realize, by adopting a high accuracy adjusting and voltage-reduction switch dimming LED (Light Emitting Diode) current constant control chip, as the BF1030 of BYD electronics, add one piece of voltage-dropping type LED constant current driving chip again, as brilliant Feng Ming source BP2832A, by the combination of two chip circuits, save phase element and circuit board, as rectifier bridge part and filter circuit can share to two pieces of driving chip, two circuit work respectively, conventional IC works always, by ordinary tap circuit Push And Release, the electric current that switch brightness-adjustable IC internal circuit regulates a road to export, reach the adjustment of brightness, finally complete the effect of colour mixture, also the effect regulating lamp brightness can be played when the light source that access two-way is identical.

With the scheme existed now, this utility model greatly can reduce Material Cost, comprise saving current rectifying and wave filtering circuit, the raising of integrated level, reduces the volume of power supply greatly, can be applied in more flexibly in different scenes, this utility model and the effect of multiple colour mixture can be reached, when switch key toning IC divides four sections of adjustment colour temperatures, just can mix out the photochromic of four kinds of styles, greatly enrich the effect of colour mixture.Also the effect regulating lamp brightness can be played when the light source that access two-way is identical.
