Q:The quality of the LED patch module

Chip manufacturers, the top chip mainly from the United States, Germany, Japan and South Korea and so on. But on the mainland LED module manufacturers to use the vast majority of chip from Taiwan, of course, there are a lot of use of chip, market positioning, the main users of the product features with the manufacturers and government policies, different chip manufacturers are different its stable performance. Maybe you will ask why not CREE, OSRAM, Nichia, first of the world's top chip manufacturers have fixed target market positioning, such as defense orders, and said, specially import a little CREE chip manufacturing module, it is also not cost-effective; and if the driver is not supporting the raw materials, it can not be completely play the advantage, so is also a great waste.

Q:What determines the brightness of the patch LED?

The brightness is consistent over a short period of time, that is, only by considering current and voltage consistency.Long term brightness is consistent with the consideration of the spacing and heat dissipation of different circuits. Uneven heat can also affect brightness.

Q:What is patch LED?

LED lights, a common model, has 34654635285050 piranha.The most common assembly of lights and PCB boards is the DIP, that is, dual in line and SMT surface mount technology two.The 346546 is the LED with two positive and negative pins, which are inserted into the PCB board after cutting the foot;3528 and 5050 are a cube with 3 LED lights inside, known as the "three in one" LED lamp. It has no pin underneath, but has a metal patch that can be passed through the reflow soldering machine through the solder to the PCB board.General indoor LED screen with more patches, outdoor screen with more pins.

Q:How does the LED placement lamp distinguish the positive and negative poles? There is no sign on the light. Thank you

The light emitting diode is fixed regardless of color. The light emitting diode 1, line: foot length is positive, the negative is short. The electrodes inside the tube can also be carefully observed, while the smaller ones are positive and the large ones, similar to the bowl, are negative. 2, SMD: overlooking the side with the color line is negative, the other side is positive.

Q:Patch LED market conditions

With good market expectations for the future status of SMD LED, all the major manufacturers have launched their own SMD LED development planning and prototype products, all of a sudden, SMD LED market showing a flourishing and lively atmosphere of contention of a hundred schools of thought.

Q:What is the principle used in SMD LED lamp, should pay attention to what the problem?

LED installation method 1, don't install the LED pin in 2, under the condition of deformation in printed circuit board when installing LED, circuit board hole center distance and LED pin center spacing should be the same, if the hole spacing will make the lamp feet have residual stress and welding...

Q:Which is good for LED patch and LED bulb?

LED (light emitting diode) patch (package)LED patch (SMD) made by FPC circuit board, LED, high quality silica gel. The waterproof performance, using low voltage DC power supply is safe and convenient, light colors, bright colors; outdoor use can be anti UV aging, yellowing, high temperature resistance and other advantages, the products are widely used in building lights, decorative lighting, advertising - Entertainment decorative lighting lighting field.LED bulbA solid state semiconductor device that converts electric energy into visible light by means of LED (light-emitting diode), which converts electricity directly into light; LED = Large, Electronic, Display,;

Q:Led lamp and Led patch two what is the difference between ah, the feeling is a patch of long service life, whether or not? 5-10 meters pan area lighting lamp selection Everbright shaped or patch shape?

Patches do some high-end things, large luminous area, from afar to see more clearly, 5-10 meters with patches better!

Q:LED patch lamp band, how to calculate how many watts a meter, such as 3528-60 beads is how much?

3528-60 is 60 meters per lamp, 3528 SMD lamp with no 5050 light, about 10 watts per meter. Copper wires have less resistance and may be less than 10 watts per meter.

Q:What does patch LED light mean?

Look, what's your product?. Some products have volume requirements, straight line will be relatively large, patches of small affixed to the circuit board does not occupy space, if only the light source, it may be an ordinary light bulb, as LED power saving.
