Decided to LED lights with the price of nine major factors
Led size: different specifications of the size of the LED price is different. Such as 0603 LED and 1210 that 3528 LED its price difference between the larger; and 1210 and 5050 specifications of the LED price difference between a step. Do not just pay attention to the price when buying LED lights. Should be from the following aspects to a comprehensive assessment, in order to buy inexpensive LED lights with.
LED lights with the use of chips: chip and Taiwan chip and imported chips (including the US chip, the Japanese chip, the German chip, etc.). Chip different, the price difference is very large. At present the most expensive US chip, followed by the Japanese chip and the German chip, the lowest price of Taiwan chips, cooling performance is slightly worse. What exactly is the chip? What kind of effect to achieve? Before you buy the first number of mind.
LED package: sub-resin package and silicone package. The price of the resin package is cheaper. The other is the same. Silicone package heat dissipation is good, so the price is slightly more expensive than the resin package.
LED color consistency: At present there are many domestic packaging plant. Large and small plus there are thousands, of course, there is the strength of the strength of the points. There are many small packaging plant because there is no split color separation machine, so either split color separation, or is outgoing, so that the quality is difficult to guarantee. No color separation of the LED color consistency is poor, installed in the LED lights on the effect after the light is not so good, of course, the price difference is relatively large.
LED welding effect: LED lamp with the assembly of manual welding and machine welding two. Manual welding is the use of soldering iron, using the most primitive method of welding. This mode of operation into the product is a ugly appearance (solder joint size inconsistent Fuzhou LED electronic display) Second, the electrostatic maintenance measures are not good, many LED chips were breakdown, resulting in power when the phenomenon of light or not bright. Machine welding is reflow soldering, machine welding is not the same. Not only after the welding of the product looks beautiful (solder joint size consistent, solder joints smooth, no flux residue, LED package intact) and the chip will not be the phenomenon of electrostatic burnout. At the same time, LED location and direction are more beautiful. This can be seen directly from the appearance.
FPC material: FPC partial pressure copper and copper two. Copper plate is cheaper, more expensive copper rolling. Copper plate of the pad in the bend easily fall off, and rolling copper will not. Which kind of material to use the specific FPC to see the seller according to their own use of the environment to make decisions.
FPC with or without environmental certification, UL certification? Whether the patent LED. No price is cheap. There is a certified and patented price is more expensive.
LED brightness: different brightness of the LED price is different. Ordinary brightness and highlight the price difference between the LED is very poor. Therefore, when buying must be clear to know what kind of brightness, so that the ability to accurately locate their own products.
LED color: different colors. The price is different. Red, green and other color color is more difficult, so the price is higher than the price of other colors; red, yellow, blue and other color separation is easier, and consistency is better, so the price is slightly cheaper. Special colors such as purple, brown and so on because of color reasons, the price is the most expensive.
