Q:What does "1210" mean in patch LED?

1210 refers to the lamp specifications.LED common lamp specifications and parameters of patch0603, 0805, 1210, 3528, 5050 refers to the LED lamp belt, often used in light-emitting components ----LED size (English / Metric) name, for example, 0603 refers to the length of 0.06 inches, width of 0.03 inches. But note that the 3528 and 5050 units are metric

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?

The main difference is the encapsulation method. The liquid silicone is mainly encapsulated and encapsulated, while the gum cake is solid and adopts a transfer molding package. Of course, there is a fundamental difference between the material, silica gel can be used for white light high-power LED, suitable for lighting. The epoxy can only be used in low-power monochrome LED, suitable for display, backlight, induction and other components.

Q:Notes on patch LED

Moisture proof, in order to avoid the products in the transport and storage of moisture, SMD LED packaging is moisture-proof aluminum packaging, and packaging bag containing a desiccant and humidity card, mainly to control the desiccant bag, humidity, humidity card is mainly to monitor the packaging bag of humidity

Q:The ten patch LED lights are connected in parallel. The rated power is 5 watts. How much voltage do you need?

Shunt split current series split voltageIs your single lamp voltage rated voltageIn addition to the red and green LED lights, the voltage is between 2 and 2.4, and the other colors are 3 to 3.6V

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:The quality of the LED patch module

Chip size. The larger the size of the same chip, the higher the general brightness, the stronger the bearing capacity, the higher the stability performance, of course, the price is relatively high. The size of the module chips now includes: 9MIL, 10MIL, 12MIL, 14MIL, 23MIL, and so on.

Q:What, in what way do I shunt the 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:LED light SMD LED package in what form, trouble you under the guidance of...

Draw your own line, mm is replaced by mil on the line, with vernier caliper measurement, or know the model, count the number of mil. For example, 5050 is a close square with a width of 5.0mm*5.0mmInline LED (such as straw hat lights, 5mm), piranha LED, surface mount LEDSinglechip collection from hardware to software chm

Q:What determines the brightness of the patch LED?

The current through the lamp itself. If the same lamp, so it is necessary to ensure consistency in the different current circuit, the test voltage of little significance, especially in the case of parallel lamp, current a few beads each share is not the same, some big, some small.

Q:Does anyone know what the current rating of a white high brightness LED patch is? Where can I find out?

The high power 1W is 350MA, and 3W is 700MA. They are all fixed and can be found everywhere.
