Q:What is the rated current for the white patch LED?
LED high power and low power, small white rated current and LED wafer, such as a chip is 20MA two 40MA.... High power 0.5W, 100-150MA, 1W, 350MA current rating in the relevant product specifications
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:How many volts is a single LED on the LED patch band?
3V or so, generally three, a group plus a resistor, power supply with 12V
Q:What determines the brightness of the patch LED?
Lamp brightness level itself, is also in the rated current situation, its brightness
Q:How to install the patch LED lamp band?
Installed indoors, you can directly tear off the stickers on the 3M double-sided adhesive surface, and then fix the light bar where it needs to be installed. Just press it with your hands.
Q:LED package and LED SMD LED lamp, what is the difference? Will the release agent be used in that part?
They differ in form and belong to the SMDLED category. Encapsulation uses liquid silicone and epoxy resins as well. The patches are basically made of epoxy resin. Relatively speaking, the amount of liquid silica should be relatively large.
Q:The ten patch LED lights are connected in parallel. The rated power is 5 watts. How much voltage do you need?
The voltage needs to be determined according to the product specification, usually 3.1 - 3.5V
Q:How many voltages and how many W drivers are used in series and parallel connection with 20 1W patches LED?
In series, the voltage is 20 times the rated voltage, in parallel, the voltage is rated voltage, but in tandem, a LED is broken, it is not bright, so it is recommended not to use it.
Q:Indoor full color LED display module and LED what is the difference between a full color?
The classification of the LED display according to the installation environment: indoor LED display screen, semi outdoor LED display, outdoor LED display; according to color: color LED screen, dual color LED display screen, LED display screen, the color LED display screen; according to the functional area can be divided into graphic screen, screen, screen, screen, digital dot matrix digital hybrid screen.
Q:Welding method and notice of SMT LED
It is best to use a hot-air gun heat transfer high air volume adjustable low moment welding, the specific heat jump to the appropriate place to see what you use what kind of welding wire, welding wire of different because of the different melting point impurities also some differences. The air volume is too high, easy to blow the original
