Q: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?: Epoxy resins turn yellow during short wave irradiation or long periods of high temperature, so they are very short lived when applied to high power lighting. That's why the LED lighting market is dominated by silica gel.But because of the low price of epoxy resin (silica gel and not at a level), and storage, use and processing is superior to silica gel, so the low power LED and some optical components still use epoxy resin package.

Q:Notes on patch LED: Storage bags are sealed and stored at a temperature of <40 DEG C.

Q:Patch LED light broken one, short circuit can use it?: Can not casually short-circuit, according to the LED connection, but also to see the power supply voltage and current, all the LED can not flow. Any short circuit may cause excess LED to flow over or over, causing a chain reaction, a bad string,...... .

Q:What is the difference between patch LED beads and LED beads: General: Patch is a LED lamp, 0805, SMD beads 3014, 3528, 2835, 5050, 5630, 5730 and so on.

Q: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?: If you choose the brightness of blue light in the light of the relatively high, so when debugging the white balance (by changing the resistance to change the current, and then change the RGB brightness LED lamp), it is difficult to transfer to the pure white. Therefore, when selecting the lamp, the blue light is generally not bright.

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:How to detect LED SMD beads: The output voltage of the digital clock diode file is not high, generally below 2.5V, so the measurement of LED lamp does not work, the best way is to external electrical measurement. If there are a lot of beads to measure it, can take a constant current power measurement.

Q:LED light SMD LED package in what form, trouble you under the guidance of...: There are 3 types of LED packages: inline LED, piranha LED, and surface mount LED

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:LED patch lamp band, how to calculate how many watts a meter, such as 3528-60 beads is how much?: 3528 single lamp is 0.06W 0.06*60 lamp =3.6W 3528-60 bead is 3.6W/ meters
