Abstract
The utility model provides an LED (Light Emitting Diode) daylight lamp, which comprises a plurality of LED (Light Emitting Diode) lamp series branches which are connected in parallel, wherein each LED lamp series branch is formed by connecting a plurality of LED lamps in series, and each LED lamp in any LED lamp series branch is connected with a voltage-regulator diode in parallel. During the normal period, the voltage of two ends of each LED lamp is smaller than the voltage regulation value of the voltage-regulator diode, and the voltage-regulator diode does not work. When any LED lamp in one series branch is damaged, the voltage of the parallel voltage-regulator diode can automatically rise to the voltage regulation value to open the voltage-regulator diode, the current passes through the voltage-regulator diode to form a passageway, the series branch can not open circuit, and other normal LED lamps can normally give out light.
Description
[technical field]
The utility model relates to a kind of lighting, but particularly a kind of LED fluorescent lamp of stabilized illumination.
[background technology]
The LED fluorescent lamp is used widely because of it has superior luminescent properties.After some occasions needs a plurality of LED lamps are connected in series a plurality of branch roads again with a plurality of branch roads and be connected into a LED fluorescent lamp and use, this application mode, as long as there is a LED lamp to damage in arbitrary branch road, will cause this branch road open circuit, make other normal LED lamp of this branch road all not luminous, use the inconvenience and the wasting of resources thereby cause.
[summary of the invention]
The technical problems to be solved in the utility model is to provide a kind of LED fluorescent lamp, when whichever LED lamp in certain series arm damages, all can not cause this series arm open circuit.
The utility model is achieved in that a kind of LED fluorescent lamp, comprise that a plurality of LED lamp series arms are connected in parallel, described LED lamp series arm is connected in series by a plurality of LED lamps and forms, wherein, and the Zener diode that all is connected in parallel of each the LED lamp in described arbitrary LED lamp series arm.
The utlity model has following advantage: the Zener diode that all is connected in parallel of each the LED lamp in arbitrary LED lamp series arm, just often, the voltage at LED lamp two ends is less than the voltage stabilizing value of Zener diode, Zener diode is not worked, when whichever LED lamp in certain series arm damages, the voltage on the Zener diode in parallel can rise to the voltage stabilizing value automatically and make Zener diode open-minded, electric current constitutes path by this Zener diode, can not cause this series arm open circuit, other normal LED lamp all can be normally luminous, do not influence use.
[description of drawings]
In conjunction with the embodiments the utility model is further described with reference to the accompanying drawings.
Fig. 1 is the utility model LED daylight lamp circuit connection diagram.
[specific embodiment]
Seeing also shown in Figure 1ly, is the utility model LED daylight lamp circuit connection diagram.This LED fluorescent lamp 1, comprise that a plurality of LED lamp series arms 12 are connected in parallel, described LED lamp series arm 12 is connected in series by a plurality of LED lamps 14 and forms, wherein, and each LED lamp 14 of 12 Zener diode 16 that all is connected in parallel in described arbitrary LED lamp series arm.Just often, the voltage at LED lamp 14 two ends is less than the voltage stabilizing value of Zener diode 16, Zener diode 16 is not worked, when whichever LED lamp in certain LED lamp series arm 12 14 damages, the voltage at Zener diode 16 two ends rises to the voltage stabilizing value and makes Zener diode 16 conductings, and electric current can constitute path by this Zener diode 16, can not cause this LED lamp series arm 12 open circuits, these LED lamp series arm 12 other normal LED lamps 14 all can be normally luminous, do not influence use.
Claims (1)
1. LED fluorescent lamp, comprise that a plurality of LED lamp series arms are connected in parallel, described LED lamp series arm is connected in series by a plurality of LED lamps and forms, and it is characterized in that: the Zener diode that all is connected in parallel of each the LED lamp in described arbitrary LED lamp series arm.
