Description

LED fluorescent lamp

technical field

The utility model relates to a light-emitting lamp, in particular to an LED fluorescent lamp using LED light-emitting diodes.

Background technique

In the prior art, in order to save energy, diode light-emitting lamps are being vigorously promoted. Existing diode light-emitting lamps generate a lot of heat, have poor stability, and are not very versatile. The cost is high. In addition, each group of luminous tubes in the existing diode light-emitting lamps is connected in series, and the method of connecting in parallel and then in series is not adopted. Therefore, when one of the luminous tubes is damaged, due to this If the circuit of the group is disconnected, the other luminous tubes connected in series in this group will not emit light, thus affecting the luminous brightness of the entire lamp.

Utility model content

The purpose of this utility model is to provide an LED fluorescent lamp, which can directly replace the existing ordinary fluorescent lamp, and when one of the luminous tubes is damaged, it will not affect the work of other luminous tubes.

Provided is an LED fluorescent lamp, which includes a lamp housing, and also includes multiple groups of LED light-emitting tubes arranged in the lamp housing. Multiple groups of LED light-emitting tubes are connected in parallel, and the ends of different names of adjacent groups are connected in series to form a network-like light emitting tube. In the array light group, the total positive and negative poles connected in parallel are connected to the output port of a built-in power module.

In the above-mentioned LED fluorescent lamp, each group of luminous tubes is connected in series with 18 luminous tubes, and 15 groups of LED luminous tubes are connected in parallel.

In the above-mentioned LED fluorescent lamp, the output voltage of the built-in constant power supply is 58-65VDC, 240-260mA. The PCB of the LED light-emitting array lamp set is made of 94V0CEM-1 material.

The utility model has the following advantages: the built-in power supply of 58-65VDC is adopted, the voltage is not high, the safety factor is high, and the power supply within this voltage range generates low heat; in addition, the built-in power supply can be used in series with ordinary fluorescent tube ballasts, No need to replace the existing fluorescent lamp bracket, no need to change the circuit, just remove the starter from the traditional fluorescent lamp rack, and directly replace the original lamp tube to save electricity by 60%; strong versatility: 15 LED light-emitting tubes are connected in parallel and then connected in series, a total of 18 groups are connected in series, forming a network array. The advantage of this arrangement is that when one LED in the same group is abnormally damaged, only this LED will not light up, and the other LEDs in the same group will not be affected. The loss is small, and there is no need to replace the lamp tube, thereby prolonging the service life of the lamp tube.

Fig. 1 is the schematic circuit diagram of the utility model LED fluorescent lamp.

Detailed ways

As shown in Fig. 1, an LED fluorescent lamp is provided, which is provided with a lamp housing, and multiple groups of LED light-emitting tubes 3 are arranged in the lamp housing, and multiple groups of LED light-emitting tubes 3 are connected in parallel, and the opposite ends of adjacent groups are connected in series Finally, a network-like light-emitting array lamp group 2 is formed, and the total positive and negative electrodes connected in parallel are connected with a power output port of a power module 1 built in the lamp housing.

In the above-mentioned LED fluorescent lamp, each group of luminous tubes is connected in series with 18 luminous tubes, and 15 groups of LED luminous tubes 3 are connected in parallel. It is also possible to set multiple or multiple groups of luminous tubes 3 to be connected in parallel as required; the luminous tubes are assembled by patch components.

The output voltage of the built-in constant power supply is 58-65VDC, 240-260mA. The PCB of the LED light-emitting array light group is made of 94V0CEM-1 material.

The voltage of the built-in power supply of 58-65VDC is not high, and the safety factor is high. At the same time, the power supply within this voltage range has low heat generation; this kind of built-in power supply can be used in series with ordinary fluorescent lamp ballasts, without replacing the existing fluorescent lamp circuit and bracket. , no need to change the circuit, remove the starter from the traditional fluorescent lamp stand, and directly replace the original lamp to save electricity by 60%; strong versatility, 15 LED light-emitting tubes are connected in parallel and then connected in series, a total of 18 groups are connected in series, forming a network Array, the advantage of this arrangement is: when one of the LEDs in the same group is damaged abnormally, only the LED is not lit, and the other LEDs in the same group are not affected, the brightness loss is very small, and there is no need to replace the lamp .
