Abstract
The utility model discloses an LED series lamp group which comprises a plurality of LEDs, wherein the LEDs are connected in series together, and each LED comprises an LED illuminant and parallel voltage regulator diodes. The LED illuminants and the voltage regulator diodes are simultaneously encapsulated inside the LEDs. The plurality of LEDs are connected in series and used together, so that the LED series lamp group has high luminous efficiency; the current passing through each LED is small, thus the LED has low heat productivity; in addition, the LED series lamp group only has a group of currents, thus the currents are very stable, the currents are still stable even through one LED is damaged, and the phenomenon that the whole LED series lamp group is not lightened can not occur by adding the parallel voltage regulator diodes.
Description
Technical field:
The utility model relates to technical field of lamps, especially relates to a kind of LED lamp group.
Background technology:
LED (light emitting diode) is one of common light source, has advantages such as consumed power is low, long service life, no ultraviolet radiation owing to it and obtains more and more widely application, and using the LED illumination to substitute existing lighting will become trend.Present LED lamp group is all in parallel the use, and is big by electric current, caloric value is high, luminous efficiency is low and every group of electric current inequality.Its each LED of led light source shown in Figure 1 promptly adopts the connection of three groups of incidence matrixs, and three groups of electric current I 1, I2, I3 be balance not necessarily, if there is a LED to damage, the electric current that flows through other LED will increase, and quickens the damage of led light source easily.
The utility model content:
The purpose of this utility model is the weak point that exists at prior art and a kind of LED series lamp group is provided, it have little by electric current, caloric value is low, luminous efficiency is high, the characteristics of long service life.
For achieving the above object, LED series lamp group of the present utility model is made of a plurality of LED that are cascaded, and each LED comprises LED illuminator and Zener diode in parallel.
Described LED illuminator and Zener diode are packaged in LED inside simultaneously.
The beneficial effects of the utility model are: it is a plurality of LED use that is cascaded, the luminous efficiency height, and little by the electric current of each LED, the LED caloric value is low; In addition, it has only one group of electric current, so electric current is highly stable, even there is a LED to damage, electric current is still the same, adds and is parallel with Zener diode, does not have the situation appearance that whole LED lamp group does not work.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is further described:
Accompanying drawing 1 is the circuit theory diagrams of existing LED lamp group;
Accompanying drawing 2 is circuit theory diagrams of the present utility model.
The specific embodiment:
The following stated only is preferred embodiment of the present utility model, does not therefore limit protection domain of the present utility model.
See shown in the accompanying drawing 1: LED series lamp group of the present utility model is made of a plurality of LED10 that are cascaded, and each LED10 comprises LED illuminator 11 and Zener diode 12 in parallel.LED illuminator 11 and Zener diode 12 are packaged in LED10 inside simultaneously, have only one group of electric current I 1 during work, even the LED illuminator of certain LED10 inside 11 damages, also can not influence the normal use of whole LED lamp group.
Claims (2)
1. LED series lamp group is characterized in that: it is made of a plurality of LED that are cascaded (10), and each LED (10) comprises LED illuminator (11) and Zener diode (12) in parallel.
2. LED series lamp group according to claim 1 is characterized in that: described LED illuminator (11) and Zener diode (12) are packaged in LED (10) inside simultaneously.
