Description

LED lamp driver device

Technical field

The improvement design of the relevant a kind of LED lamp driver device of the utility model mainly is to utilize the effect of burning voltage, electric current to cooperate the effect of rectification, makes the LED lamp be reached voltage stabilizing and all-wave is luminous, and does not produce the purpose of the perceptible flicker of human eye.

Background technology

The prior art relevant with the utility model has M311833 number novel patent of tw Taiwan patent as shown in Figure 1, this patent case is utilized the current limliting pressure stabilization function of resistor and capacitor because of it, and can under alternating current all-wave shape, operate, reach the lamp string and use required three-wire type requirement, but resistor is followed an ohm theorem, electric current just increases when voltage raises, make its effect under the unsettled environment of input voltage, light emitting diode is burnt, and the electrolytic capacitor volume that uses is too big, make that the hardware volume on using is relatively also excessive, not good to the protection effect of light emitting diode yet; Figure 2 shows that M356843 number novel patent of tw Taiwan patent for another example, this patent case makes it can't reach the effect that can continue to be connected in series because of the restriction of circuit design, that is is unfavorable for the productive value on the lamp string industry; Be illustrated in figure 3 as M351310 number novel patent of tw Taiwan patent in addition, this patent case is too much because of the passive device in its circuit design such as elements such as resistance, electric capacity, and circuit can't use with the simplest three-way lamp string that needs serial connection to use of reaching, and limited applicable scope.

Summary of the invention

When main purpose of the present utility model is a kind of circuit design of LED lamp is provided, utilize the high characteristic of the linear galvanostat stability of active member and the effect of dual collocation, making LED lamp of the present utility model reach all-wave uses, and be able to the three-way application that needs serial connection of reaching, can be widely used in fields such as LED bulb, fluorescent tube and lamp string.

In order to achieve the above object, the utility model provides a kind of LED lamp driver device, includes:

Group diode before one, it is formed by two diode reverse butt joints;

The specific embodiment

See also Fig. 4 to shown in Figure 6, the utility model is a kind of LED lamp driver device, LED lamp driver in Fig. 4 mainly is made up of preceding group of diode 1, lamp group 2, threshold currents device 3 and back group diode 4, group diode 1 is oppositely docked by

diode

11,12 and forms wherein, then organizing diode 4 is forward docked by

diode

41,42 and forms, therefore when this device carries out electrically conducting, by the burning voltage of threshold currents device 3, the effect of electric current, can keep lamp group 2 luminous, and have simple structure and the little effect of volume with all-wave.

See also shown in Figure 5, group diode 1 rear end and before the threshold currents device 3 in the utility model LED lamp driver is serially connected in the position of lamp group 2 front ends.

See also shown in Figure 6, threshold currents device 3 in the utility model LED lamp driver can be serially connected in the front and back ends position of lamp group 2 respectively simultaneously, so can avoid threshold currents device 3 to cause the short circuit electric circuit high-tension electricity directly across LED lamp group 2 in single damage, cause big electric current to cause the damage of LED lamp, keep burning voltage and electrically conducting to keep LED lamp group 2 operate as normal and can reach.

See also Fig. 7 to shown in Figure 8; the another kind of LED lamp driver of the utility model device; but diode group 4 reverse parallel connections serial connection wherein, and cooperate threshold currents device 6 and be connected in an end of the LED bulb group 5 of twin-core sheet (CHIP), it also can keep protecting the effect of LED lamp and all-wave stabilized illumination.

In sum, the utility model can solve the existing shortcoming that has existed for a long time with LED lamp group leader really, is one to have the utility model of patentability, and can reaches the practical value of utilizing on the industry, proposes novel patent application in accordance with the law.

More than explanation is just illustrative for the utility model; and it is nonrestrictive; those of ordinary skills understand; under the situation of the spirit and scope that do not break away from claims and limited; can make many modifications, variation or equivalence, but all will fall in the protection domain of the present utility model.
