Background technology
LED lamp is light emitting diode, and it is applied in lighting apparatus widely.Through checking, the life-span of LED lamp is 100 times of ordinary incandescent lamp, and power consumption is well below incandescent lamp, and the cost of changing is also lower.The function of existing flexible LED lamp more comprehensively, not only for general lighting, and can play good decoration function.Existing flexible LDE lamp band has been widely used in landscape art, commercial advertisement and amusement decoration places.Its advantage is arbitrarily to bend moulding, cuts randomly.
General, the color of LED lamp defines by the type of diode, by using dissimilar diode combinations, can make lamp bar produce different colors and brightness.LED lamp band is generally encapsulated on circuit board.
Full-color LED lamp bar, due to its color variation, can be realized various effect under the cooperation of controller, is more and more subject to user's favor.The array that full-color lamp bar forms more can be realized low cost, the LED display of high reliability.Traditional full-color lamp bar is take 12V and 5V as main, in the product of 12V, and general three LED lamp that drive of IC, its pixel is more discrete, and in the product of 5V, a general IC drives a LED lamp, and its pixel point density is the highest, and the effect of realization is also better.But pixel point density is higher, the electric current of its consumption is larger, and common length is the LED lamp bar of a meter, in the time that brightness is the highest, can consume about 2A electric current.Along with the integrated LED lamp of built-in IC occurs, picture element density has been brought up to one meter 60, even higher, and the electric current that now a rice lamp bar consumes can be up to 3.6A, and that this class lamp bar is generally 5 meter of one volume is even higher, and current value in theory can be up to 18A.Be generally FPC or FR4 material for the sheet material of making lamp bar, the width of plank is also only 10mm, cannot bear so large electric current.In this application, conventionally can cause two problems to occur: the normal working distance defection of lamp bar is significantly shortened, cannot normally work to the length of 5 meters, there is flicker in the lantern festival far away apart from power supply; The colour consistency of lamp bar is poor, near higher, far away apart from the power supply lamp of lamp brightness of distance power supply in lamp bar, and brightness is lower, and aberration is large.
In order to solve above-mentioned deficiency of the prior art, the utility model proposes a kind of new solution.
Utility model content
The purpose of this utility model is to provide one kind of multiple power supply modes, reduces voltage drop, thereby promotes effective active length of lamp bar, solves the situation of the inconsistent and Luminance Distribution inequality of aberration simultaneously.
For reaching above-mentioned purpose, the technical scheme that the utility model adopts is: the soft lamp bar of a kind of LED is provided, comprise substrate and be printed on the power bus in substrate, substrate is provided with the power port and the IC that are connected with power bus, IC is electrically connected with LED lamp pearl, described power bus comprises 5V power bus and 12V power bus, wherein 5V power bus is electrically connected with LED lamp pearl, wherein 12V power bus is connected with some dc source administration modules, and each dc source administration module will be respectively 25 ~ 35 LED lamp pearl parallel operations after input voltage step-down.
Preferably, substrate is pcb board; Voltage after the step-down of dc source administration module is 4V.
Preferably, LED lamp pearl comprises LED lamp pearl and the adjustable LED lamp pearl of brightness that color is adjustable.
Preferably, dc source administration module and LED lamp pearl are separately fixed at substrate both sides.
Preferably, dc source administration module will be respectively 30 LED lamp pearl parallel operations after input voltage step-down.
In sum, the utlity model has following advantage:
The utility model is by increasing the power bus of 12V, promote supply voltage, improve the power supply architecture in lamp bar, adopt distributed power source is the power supply of LED lamp simultaneously, significantly reduce the electric current in power bus, increased the voltage range of LED lamp bar steady operation, the normal active length that has effectively extended lamp bar, reduce the heating of lamp bar simultaneously, promoted the stability of lamp bar.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model;
Fig. 2 is the side view of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in detail.
