Abstract

The utility model relates to an LED lamp with a voltage stabilizing tube, which consists of several LED lamps connected in series to form a group, multiple groups of LED lamps are connected in parallel and then connected to a power supply, and in the series connected LED lamps, every 2 to 6 LED lamps are connected in parallel with a stabilizer tube. pressure tube, and at the same time, a resistor is connected in series with the LED lamps grouped in series. Compared with the existing technology, this design is easy to install. When an LED lamp in the lamp group has an open-circuit fault during use, the voltage regulator tube can be used to conduct the circuit, thus keeping the entire circuit conducting, so that other LED lamps can work normally. The passing current remains unchanged, which avoids the phenomenon that the entire lamp group does not light up due to damage to one LED lamp. When encountering voltage fluctuations at both ends of the lamp group, the voltage regulator tube can also play a role in stabilizing the voltage and buffering, without affecting the LED. Lamp service life and luminous effect.

Description

LED light with Zener tube

technical field

The utility model relates to an LED lamp group, in particular to an LED lamp with a voltage stabilizing tube.

Background technique

Light-emitting diode (LED) lamps are widely used in various occasions because of their energy saving and long service life, especially in lighting fixtures, and such lighting fixtures will gradually replace fluorescent lamps or ordinary light bulbs as lighting sources. In the process of use, several LED lights are often connected in series to form a group, and multiple groups are connected in parallel to the power supply for use, such as festival lights. When there is an open circuit fault due to false welding or quality problems of the LED itself, the result will be that the entire group of LED lights will not light up, not only will the visual effect be lost, but also for the LED load powered by constant current, the entire current will be added to the other groups, so It will shorten the life of LED lamps.

Contents of the invention

The purpose of the invention of the utility model is to avoid the defects of the prior art and provide an LED lamp with a voltage regulator tube that can still keep the entire circuit conducting when an open circuit fault occurs in the LED lamp group, so that the LED lamp can be used normally and the service life can be improved. .

According to the purpose of the above invention, the utility model is realized through the following technical solutions: an LED lamp with a voltage regulator tube, which includes a plurality of LED lamps connected in series to form a group, and multiple groups are connected in parallel to the power supply, which is characterized in that the series In the group of LED lamps, every 2 to 6 LED lamps are connected in parallel with a voltage regulator tube.

A resistor is connected in series in the series-connected LED lamp groups.

Compared with the prior art, because the utility model adopts the method of parallel connection of voltage regulator tubes, even if one of the LEDs fails, only a few LEDs connected in parallel with the voltage regulator tubes will not light up, which will not affect the normal operation of other LED lights. The passing current is also unchanged, the luminous effect and service life are hardly affected, and the installation is convenient.

Description of drawings

Fig. 1 has provided the circuit connection structural diagram of the utility model.

Detailed ways

The LED lamp with a voltage regulator, as shown in Figure 1, consists of several LED lights connected in series, and a voltage regulator D is connected in parallel to each 3 LED lights to conduct the entire circuit, and the LEDs are connected in series to form a group. A resistor R is connected in series in the lamp group, which is used for current sharing and current limiting, and multiple groups of LED lamps connected in series are connected in parallel and then connected to the power supply. During use, when an open-circuit fault occurs in one of the LED lamps in the lamp group, the voltage regulator tube D can conduct the circuit, thus maintaining the conduction of the entire circuit, so that other LED lamps can work normally, and the passing current remains unchanged. If one LED lamp is damaged, the whole lamp group will not light up; when the voltage applied to both ends of the lamp group fluctuates, the voltage regulator tube can also play a role in stabilizing the voltage and buffering, without affecting the service life and luminous effect of the LED lamp.
