Abstract
The utility model discloses a circuit capable of stabilizing voltages of light emitting diodes. The circuit comprises a plurality of LED lamp beads that are in series connection. The circuit is characterized in that a voltage stabilizing resistor is in parallel connection between two ends of each LED lamp bead. The voltage stabilizing resistors are in parallel connection with the LED lamp beads, so that voltages on the two ends of each LED lamp bead are stabilized, each LED lamp bead is lighting more stably, brightness of the whole LED lamp bead is more uniform, and the service life of each LED lamp bead is prolonged.
Description
Technical field
The utility model relates to a kind of LED circuit for lamp, is specifically related to a kind of stabilized illumination diode electrically volt circuit.
Background technology
The lightings such as existing fluorescent lamp, its power consumption is large, and needs the accessory such as ballast, and production cost is high, and the appearance of LED lamp then is expected to solve the problem that luminous field exists at present.And the LED light fixture has high brightness, the characteristics such as energy-conservation, use in each occasion more and more extensive, such as other indoor places such as market, bank, hospital, hotel, restaurants.
LED lamp pearl generally adopts the mode of series circuit to work, namely count the work that is together in series of LED lamp pearls, in the work of LED lamp pearl, owing to be to adopt series circuit, if one of them LED lamp pearl damages, will affect the work of whole circuit, be subjected to the impact of power supply ripple voltage, the long-term work of LED lamp pearl causes the light decay of lamp pearl to increase under high ripple voltage, and the LED lamp life shortens.Simultaneously, the internal resistance of LED lamp pearl size in the series circuit has determined the voltage of this lamp pearl, because inconsistent each LED lamp pearl both end voltage that causes of internal resistance is variant, the light fixture brightness that shows as a plurality of LED lamp pearls compositions is inconsistent, and uniformity of luminance is poor, affects visual effect.
Summary of the invention
The utility model purpose provides a kind of stabilized illumination diode electrically volt circuit of stable LED voltage of both ends of lamp, improves the uniformity of luminance of LED lamp, useful life.
For achieving the above object, the technical solution adopted in the utility model is: a kind of stabilized illumination diode electrically volt circuit, comprise that a plurality of LED lamp pearls are connected in series, and each described LED lamp pearl two ends is parallel with a voltage regulation resistance.
In the technique scheme, the internal resistance resistance of the described LED lamp pearl that each described voltage regulation resistance is corresponding with it coupling.
Utilize in the parallel circuits, voltage on each branch road is the same, the voltage that is the voltage regulation resistance two ends is consistent with LED lamp pearl both end voltage, because the resistance of resistance is easy to control in production engineering, guarantee that each resistance value is error free, thus the resistance both end voltage (U=I * R) relatively stable is so that the voltage on each LED lamp pearl also equates, stablize LED lamp pearl voltage, guaranteed the consistency of luminosity.
Because technique scheme is used, the advantage that the utility model compared with prior art has is:
1, because the utility model adopts voltage regulation resistance in parallel with LED lamp pearl, when LED lamp pearl damages, can connect by voltage regulation resistance, guarantee normally lighting of light fixture; In addition, because the resistance consistency of voltage regulation resistance is good, can stable phase answer LED lamp pearl both end voltage in parallel, make the LED lamp luminescence more even, also can prevent the impact that power-supply ripple causes the LED lamp simultaneously, prolong the useful life of LED light fixture;
2, the utility model is simple in structure, is easy to realize.
Description of drawings
Fig. 1 is the circuit theory schematic diagram of the utility model embodiment one.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described:
Embodiment one: referring to shown in Figure 1, a kind of stabilized illumination diode electrically volt circuit, comprise that 3 LED lamp pearls are connected in series, each described LED lamp pearl two ends is parallel with a voltage regulation resistance R, the internal resistance resistance coupling of the described LED lamp pearl that each described voltage regulation resistance R is corresponding with it.
In the present embodiment, each LED lamp pearl two ends also meets a voltage regulation resistance R, utilize the principle that the voltage on each branch road equates in the parallel circuits, the steady resistance both end voltage is namely stablized LED lamp pearl both end voltage, because the resistance of resistance is easy to control in production engineering, guarantee that each resistance value is error free, so resistance both end voltage (U=I * R) relatively stable, so that the voltage on each LED lamp pearl also equates, reach the purpose of stablizing LED lamp pearl voltage, guaranteed the consistency of lamp luminescence brightness.
