FAQ
- How can I install the patch LED lamp belt on the wood chip casting board? With double-sided glue will be hot, and can not use the clip on the screw, what should I do?
- More attention is paid to the lamp with waterproof and the installation of a solid in the outdoor installation, outdoor installation often adopts the mode of fixed card slot, need to cut and connected place, and indoor installation, just need another with waterproof glue, waterproof effect to consolidate the connection point.
- 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.
- 0603，0805，1206，3020，3528，5050，355 what is the current and voltage of these patch LED? Please give advice!
- SMD LED specification:(1) metal stent type: 0402, 0603, 0805, 1206, 3mm, 5mm, 6mm, 8mm, 10mm and so on.(2) metal support (commonly known as small butterfly) type: 2mm, 3mm and so on.(3) TOP LED (white shell) type: 1208 (30*20), 1311 (35*28), 1312 (35*32), 2220 (55*50) and so on(4) side light LED:0905 (22*12), 1105 (28*12) 1605 (40*14) and so on.
- LED light SMD LED package in what form, trouble you under the guidance of...
- The LED chip has bumps and is welded to the PCB board using FLIP CHIP to packaging technology.LED is English light emitting diode (light emitting diode) abbreviation, its basic structure is a electroluminescent semiconductor chip light emitting materials, with silver glue or glue curing to the bracket, connecting a chip and a circuit board and then with silver or gold, then sealed with epoxy resin around, to protect the internal core role finally, the installation shell, so the seismic performance of LED lamp is good. Field of application involves mobile phones, desk lamps, household appliances and other daily household electrical appliances and machinery production.
- What is the difference between SMT LED packaging with silicone and epoxy resin transparent package? What is the market situation of these two types of packaging?
- At present, it is basically made of silica gel, and the epoxy resin is very few. Only those with lower price may use some. Why is it rare to use epoxy? Because of the use of LED epoxy patch cited some discomfort because the cable used in the above: reflow welding, high temperature resistant epoxy epoxy and silicone not lead to separation, produce decay dead lights etc..
- 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!
- LED patch lamp band, how to calculate how many watts a meter, such as 3528-60 beads is how much?
- LED patch lamp with 3528-60 beads should be 4.8W/ meters.Because the LED light belt is made according to the manufacturer's standard, the parameters are different, and the parameters of the LED lamp belt and the method of use are best connected with the manufacturer's confirmation. Some common parameters are given here for reference only
- Production of a number of substrates, the use of SMD LED lights, red lights and green lights are not bad, blue lights appear mass dark, do not know why? Is the LED blue light material easy to use dark?
- The pressure drop of the blue light is greater than that of the red light and the green light. If the series connection is the same as that of the green light and red light, the current limiting resistor will tend to dim
