Background technology
LED (Light Emitting Diode light-emitting diode) is the high-performance solid light source that a kind of novel faint electric energy of usefulness just can be luminous, and its spectrum almost all concentrates on visible light frequency band.In recent years, along with the crystalline growth technology of GaP, GaN based III-V group compound semiconductor and the progress of nanometer technology, the light efficiency of LED and high-power integrated technology all are greatly improved, and luminous efficiency is up to more than 90%.Compare with incandescent lamp, tungsten lamp and fluorescent lamp, LED has the advantage that volume is little, the life-span is long.Do not have ultraviolet ray and infrared ray in the LED spectrum, caloric value is low, energy utilization rate is high, no stroboscopic, radiationless, discarded object is recyclable, belongs to typical green illumination light source.Therefore, LED is described as the 21 century new light sources, be about to become after incandescent lamp, fluorescent lamp, high-intensity gas discharge lamp the 4th generation light source.This novel illumination light source of led light source will replace the traditional lighting light source, is just driving a new Industrial Revolution---the illumination revolution.
Adopt the LED light fixture of great power LED at present,, adopt the constant voltage driving mode to light LED mostly as LED street lamp, LED fluorescent lamp as light source.If the multiple branch circuit LED that uses in parallel, the inconsistent problem of luminosity that can occur because each paths of LEDs current unevenness etc. causes; If a large amount of serial number LEDs use, the dead lamp of a LEDs can occur and cause the dead lamp of whole piece branch road, have a strong impact on the problem of light fixture lighting effect, and the series LED number can make that too much the branch road both end voltage is too high, causes potential safety hazard.Simultaneously, because the difference of lighting environment, LED light fixture producer must select different LED numbers for use according to different lighting demands, and designs different led light source plates, has prolonged product development cycle, has improved cost, is unfavorable for being extensive use of of great power LED.
The utility model content
Technical problem to be solved in the utility model is exactly the above-mentioned shortcoming at prior art, and a kind of modularization LED constant current driving circuit plate that adopts the grouping series connection is provided.
The utility model solve the technical problem, the technical scheme that adopts is, the LED source constant-current driven module, comprise substrate, drive circuit and light-emitting diode, it is characterized in that, described drive circuit has 2 tunnel output channels at least, and described light-emitting diode packet chain is associated on the described drive circuit output channel.
The beneficial effects of the utility model are, constant-current drive circuit drives two-way or the above led light source of two-way, and each road electric current can be consistent, and has guaranteed the uniformity of led light source brightness.Single LEDs opens circuit and can not make whole module LED extinguish, and only influences this LED place branch road.Because adopt constant current drive mode, it is normally luminous that single LEDs short circuit can not influence other LED, greatly improved the reliability of the LED light fixture that this module is assembled on the circuit design.
