With the continuous maturity of the LED market and technology, LED products are becoming more and more diverse, and the quality is getting better and better. However, the price of LED products on the market is becoming more and more unspeakable, and often the same product price will vary by ten. A few yuan or even tens of dollars, want to know the mystery of the middle? And look at the small series for everyone to do the analysis:
First of all, the most important main part of the guardrail tube: the price difference of the LED lamp product. Reason: The common brightness and light decay control of the lamp bead market is better at 0.36-0.43 yuan/group RGB low price. There are 0.2/group RGBLED applications to analyze the angle: 1. The former has high brightness, long life, long light decay, small color mixing effect, good dead light rate, the latter is low brightness, short life, short light decay, obvious mixed color unevenness (after 50 mA current) After the impact test, the conclusion is that the price difference between each guardrail tube is about 7-8 yuan.
LED product price difference reason: circuit board circuit board: can be divided into wave fiber half-wave fiber flame retardant cardboard where is it?
Wave fiber board: the flexibility is not easy to break, the damage to the original device is small, the life is long, the copper skin is thick, and the overcurrent is large.
Cardboard: On the contrary, if there is strong vibration during transportation or installation, it may break the board, the copper skin is thin, and it is easy to cause copper peel in the tin. Even if it is long or there is water vapor in the tube, it will be corroded. Then the board can save 0.5-1.2 yuan.
Safety line: It should be or shouldn't be debated by many people now. Of course, it is good to add it. Of course, the overcurrent is relatively large. If it is 220V, it should be a problem if you have a connector of 15 meters. If you don't add it, Can save 0.6 yuan.
Electronic components: almost all tin: the true murder of the virtual welding 40 degrees -55 degrees, the price difference of 10-15 pieces / kg can be seen from the circuit board, of course, the good is brighter, 40 degrees is easier to fall, easy to cause virtual Welding, of course, may not all be seen at the beginning, but the time is long. When you find that the small size of the guardrail tube you bought is not the same, then the murderer is in front of you. The average is about 0.5 yuan per meter.
Next, the PC tube has a PC tube that is of course the first material and the second material or even three times. The explosion phenomenon in the general market should be related to this material. Of course, it is also related to the paint water. If you use him If the tube for the secondary or tertiary material is used for a long time, it should be rare. Generally, industrial alcohol is used, so that there is no chemical reaction. The price difference between primary and tertiary materials should be: 1.5-2.5 or so.
Waterproof: Nowadays, many manufacturers use plugs for resin. Of course, they are also made of silica gel. The hardness of silica gel is of course not enough. If you connect it in actual engineering installation, then pull it up. If it is installed, it is possible to pull the cable out or loosen it.
The plug is fixed, hot melt adhesive silica gel is used by people, the cost of playing silica gel inside and outside the tube should be about 1.5-2 yuan, but if the cost of using hot melt adhesive inside should be about 0.7-1 yuan, then we Also saved 1 yuan, so where is the difference? Bad weather will prove hot melt adhesive - no, our company put the packaged tube into the freezer for three days and then exposed it. After several times, it was found that the hot melt gel completely fell off, and the plug was easily removed. .
For the wiring: the difference between the medium and the bad price is 0.5 yuan. When installing, please don't fold it too tightly. The water is not from the joint. If you have water in the line, you can't look at the line and the pressure on the joint. The location of the terminal, you will thank me.
Ok, after the analysis is over, let's calculate the price difference. We have removed the highest price and the lowest price. Let's take a look: Lamp Bead: 7.5 yuan circuit board: 1 yuan security line: 0.6 tin: 0.5 yuan PC Tube: 2 yuan silica gel: 1. Yuan pair wiring 0.5 yuan, so the calculation is very obvious, each tube can save 13.1 yuan, then you understand why the LED product price difference is so big, right?
