Light-driving integrated LED fluorescent lamp and manufacture process thereof

Abstract

The invention relates to a light-driving integrated LED fluorescent lamp and a manufacture process thereof. The light-driving integrated LED fluorescent lamp comprises a fluorescent tube and an LED driving board device mounted in the fluorescent tube. A plug communicated with an external power supply is arranged at the end of the fluorescent tube. The light-driving integrated LED fluorescent lamp is characterized in that the LED driving board device comprises a light board distributed with LED lamps and a power supply driving board connected with the light board, the input end of the power supply driving board is communicated with the plug at the end of the fluorescent tube through a lead, and the power supply driving board and the light board are separated by a thermal conducting silicone film. In addition, the invention also provides a manufacture process of the LED fluorescent lamp which has reliable insulation, connection and quake resistance and reasonable wiring rule as well as a pin processing process of elements and devices, can avoid shorted-circuit phenomena caused by insufficient bottom wiring insulation and insulation layer piercing by the pins and can also prevent a creepage phenomenon due to the parallel operation of an AC power line of the light board and a DC from burning the light source.

Description

technical field [0001] The invention relates to the technical field of lighting products, in particular to a lamp-driven integrated LED fluorescent lamp and a manufacturing process thereof. Background technique [0002] There are roughly two ways to place the power supply of LED fluorescent lamps on the market, one is an external power supply, and the other is a built-in power supply! The built-in power supply of the built-in LED fluorescent lamp and the fixing method of the lamp board include single-end fixing and double-end fixing. . The company's LED fluorescent lamp is also a double-terminal fixing method with a built-in power supply. [0003] Now the LED fluorescent lamp with built-in power supply is on the market. The first method of double-terminal fixing is as follows: when designing the circuit board, design the power input of the lamp board just at the power output position, so that the power board can be connected to the power board with a single-core hard wire. ...

AI Technical Summary

Problems solved by technology

[0005] The disadvantages of the prior art are as follows: firstly, the double-terminal fixed LED fluorescent lamps, the low-voltage wires that input the AC power from the AC terminal and the direct current of the lamp board are laid on the same PCB together, which has potential safety hazards! If the mains power fluctuates or is unstable, the voltage may rise. When the safety distance is not enough, it will creep into the low-voltage circuit of the light board, causing all LED light sources to break down and cause heavy losses.

[0006] Secondly, there are many plug-in components on the power board. Although there is a layer of green shell paper, the pins of the components are very sharp. It is very likely to pierce the green shell paper, touch the circuit of the light board, and lead high voltage to the light board. It will break down the LED light source! In addition, most of the existing power driver boards on the market use double-sided boards, that is to say, there are lines passing through the bottom of the power board, and the voltage of the power board is usually high voltage. It is easy to cause a short circuit between the power supply and the lamp board, and burn the lamp board; and the green shell paper is also easy to fall off during assembly, transportation, and use, causing the lamp tube to be burned during use

[0007] Once again, the single-end fixed LED fluorescent lamp also has the above problems, and there is a serious problem as follows: because it is fixed at one end, the other end bears a certain gravity and vibration tension, and the LED fluorescent lamp will produce a certain length when it is working. Heat, only by the connection of two hard wires, if things go on like this, it is very likely that the solder joints will become weak or fall off! If it falls off and touches the aluminum shell, it will cause electric shock when the human body touches it, which will have serious consequences for human life.
