How to buy fluorescent lamps? The basic steps of LED fluorescent lamp installation
LED fluorescent lamps are commonly known as straight tube lamps. They are a substitute for traditional fluorescent tubes. Relatively speaking, they are more energy-efficient. Generally, fluorescent lamps are used in offices and classrooms. The better choice of lamps will be better, so how to choose fluorescent lamps purchase? What are the basic steps for installing led fluorescent lamps? Don't worry, BENWEI Lighting is here to explain it for everyone, let's take a look.

How to buy fluorescent lamps?
1. Security
In fact, this is the most basic requirement and guarantee for an LED tube. Of course, the most important factor for all products is safety. This is why Zhongxiang people put safety first in the product, including production. Safety, but often the most basic requirement, has been ignored by most LED manufacturers. What they value most is how to save costs and maximize profits instead of taking into account the interests of customers. This is why many LED lighting The reason why manufacturers continue to close down.
2. LED light source
Although the traditional plug-in LED tube products can conduct heat out through the pins, due to the extremely poor conduction ability, the heat of the LED chip will accumulate a lot over time, which greatly reduces the life of the LED lamp beads.
We use LED post film lamp beads, and its characteristics are as follows:
1. The chips are all regular square LED chips from Kellett Taiwan (Note: The quality and price of square and round chips are very different from those of raw chips, and most of Zhongshan uses raw chips). There are only two types of glue for LED packaging: Dow Corning, Shin-Etsu glue; anyone who knows a little about the LED market knows that these two glues are very expensive, 3 to 5 times the price of ordinary glues. Many manufacturers pursuing price maximization basically choose ordinary domestic glue. The products made by this product have no problems at the beginning of use. After a long time, you will find that the light decay is serious, the color of the lamp beads is easy to turn yellow, or even the lamp is dead. ,Affect.
2. 99.9999% pure gold wire is used for the lead in the LED chip. The pulling ability and thermal conductivity of the gold wire are very good, which is also the most basic common sense.
It is precisely because of the above 2 points that the thermal conductivity of our LED lamp beads is stable, so that the LED can conduct the heat of the chip to the aluminum profile when it is working, and then let the aluminum profile radiate the heat into the air. In this way, the LED chip The temperature is extremely low during operation, which guarantees the life of the LED tube to the greatest extent and slows down the light decay of the LED lamp beads.
Three, power source
The main requirement of LED drive power supply is double high, namely: high power factor (PF), high conversion efficiency. Products with a PF=0.9 and above have far exceeded the standard requirements of power grids around the world, reducing power grid pollution; while products with high conversion efficiency, electrical energy is converted to light energy at the maximum limit, reducing heat generation.
Usually there are two options for LED drive power: isolation and non-isolation. The author teaches you the most earthy way to judge whether the LED driver is isolated or non-isolated: the isolated volume is too large, and the safety factor is the highest in use. However, due to cost reasons, the market for isolated products is not as good as the cost of non-isolated products. So here the author mainly discusses non-isolated drive schemes. The following are the characteristics of our power supply:
1. Accept the normal power supply from all over the world (85V-264V), constant current IC control, general voltage fluctuation (the voltage difference between day and night is relatively large) does not affect the brightness of the LED, ensuring constant brightness and chip work temperature;
2. Low power consumption, the conversion efficiency of the power supply is as high as 0.9, and the power factor is as high as 92%;
3. With load open circuit protection, short circuit protection, output overvoltage protection and other functions, the current ripple characteristic is good, the output current is similar to DC, and no light flicker is guaranteed;
Four, heat dissipation
Everyone knows that the most important thing about the lifespan of an LED is whether the heat is dissipated. As we all know, there are three ways to dissipate heat: conduction, convection and radiation.
The following are the heat dissipation characteristics of Zhongxiang Innovative Technology LED tube:
1. The use of high-quality aluminum substrates with a thermal conductivity of 1.2 and high-quality LED lamp beads ensure the smooth conduction of heat from the chip to the aluminum substrate. The quality of the aluminum substrate determines whether the heat can be transferred to the aluminum substrate. On aluminum profile;
2. The aluminum substrate with the LED lamp beads is tightly attached to the aluminum profile through the thermal paste to make the heat flow smoothly, which is different from the phenomenon that the contact surface between the aluminum substrate and the shell of the general LED tube is too small and the heat conduction is not smooth.
After the above heat dissipation treatment, under the working environment temperature of 25 ℃, the LED tube produced by Zhongxiang Innovation Technology has been tested and found that the shell temperature is about 45 degrees, and the normal temperature rise is 13-15 degrees. At this time, the LED chip works The temperature is around 60 degrees.

The basic steps of LED fluorescent lamp installation:
1. First remove the old fluorescent tube, which has springs on both sides, push it to one side with a little force, and it will come out.
2. Then remove the bracket cover, press the bottom plate with your left hand, hold the cover with your right hand and pull it up to remove the cover.
3. Then remove the electronic ballast, cut off the input and output wires of the electronic ballast with diagonal pliers, and use a screwdriver to unscrew the screws that fix the electronic ballast, then the electronic ballast can be easily removed.
4. Then it is the wiring. Connect the wires of the power grid and the inlet wires of the bracket, and wrap them with electrical tape.
5. Then close the cover plate tightly, straighten out the wrapped wires, and fix them in the wire groove of the bracket, hold the cover plate with both hands, and press down firmly to cover the cover plate.
6. Finally, install the LED tube, insert the wiring at both ends of the LED tube into the mounting seam of the bracket, and then you can easily put it in and install it.
