9 of the main factors affect the price of LED lights belt

purchasing LED lights belt, don't just focus on the price. Now teach you from the following several aspects to the comprehensive evaluation, in order to get the best cost-effective LED lamp belt.

1, LED lights belt adopts chip: there are domestic and Taiwan chip and chip (entrance Including the United States, Germany, Japan cmos chip, etc. ) 。 The chip is different, the price difference is very big. At present the most expensive is the chip, followed by Japan and Germany chip, price moderate Taiwan chip. Detailed the chip? To achieve what kind of effect? Let the affair before purchasing.

2, LED encapsulation: resin encapsulation and silica gel encapsulation. Price of resin encapsulation is cheaper, due to the heat dissipation function is a bit poor, the other is the same. Silica gel encapsulation cooling function is good, so the price a little expensive than resin encapsulation.

3, LED color consistency: the need to have a lot assembly house, large and small combined there are thousands of home, of course, also have strong and weak points of the power. Have greatly small assembly house because there is no testing machine, so either not testing, or outgoing, so it is difficult to guarantee for quality. No LED by spectral color separation, the color consistency is bad, in the LED lamp with light after the effect is not so good, of course the price difference is bigger.

4, LED welding effect: commercial ceiling lamps belt assembly manual welding and welding machine, manual welding is to use iron, using the most primitive way to welding. This way of work out a product is a shame ( Spot size inconsistent, flux residues, solder joint is not smooth, LED encapsulation was burnt, etc. ) And electrostatic protection is not good, a lot of LED chip is punctured, lead to careless or not on the light when electricity phenomenon.

welding is different to the machine, reflow soldering machine welding is used welding, after welding products not only look beautiful, Spot size is consistent, solder joint is smooth, helpless, flux residues, LED packaging in good condition) And will not be electrostatic chips on the burn out. At the same time, the LED position and direction are more beautiful. This can be seen directly from the appearance.

5, FPC material: FPC copper rolling of copper and apply two, apply the copper plate is cheaper, rolled copper is more expensive. Apply the copper welding plate fall off easily when bending, and rolling of copper will not. Detailed adopt what kind of material of FPC, to see whether the buyers themselves according to use environment to make a decision.

6, FPC presence through environmental certification, UL certification? Leds have patent, etc. Through the certification and patents, the price is more expensive, not cheap.

7, the brightness of the LED: different brightness LED price, ordinary brightness and highlight LED price comparison. Therefore, when purchasing must clearly know oneself need is what kind of brightness, so as to correct positioning their products.

8, LED color: the color is different, the price is different. Because the color white, green and testing is difficult, so the prices higher than the price of the other colors to; Red, yellow, blue wait for color testing more easily, and consistency is better, so the price a little cheaper. Special color because the color such as purple, brown, its price is the most expensive.

9, the size of leds, LED the size of different specification, the price is different. Such as LED, 0603, and 1210 ( That is, 3528) LED, its price is large difference; And the price of 1210 and 5050 specifications of the LED and a step.
