Q:What does patch LED light mean?
The screen is divided into standard lamp and patch type, the light emitting diode lamp is inserted into the circuit board, and the patch is a patch welded on the circuit board. Two light sources are not the same. If only light, not so clear.
Q:Is the forward voltage drop of the patch LED too large or too small?
The pressure drop in the normal range is generally better. The smaller the pressure drop, the lower the power dissipation. The more you save the electricity bill.But not to say that the smaller the better, not in the normal range of low pressure drop products may be defective.In addition, the uniformity of the LED pressure drop is also important.
Q:Why is the patch LED blue light dim?
When making a batch of LED lights, the brightness values of various lights are in accordance with certain rules. Due to achieve a white balance, three RGB color brightness required by the ratio of 3:6:1, that is to say the blue light required brightness is very low.
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
Q:How many voltages and how many W drivers are used in series and parallel connection with 20 1W patches LED?
LED lights are current driven, first of all, look at your LED's IF and VF values. How much power do you have?. Make sure the current is in line with the IF and the current limit can be achieved with resistors.
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: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:How do led patches measure good or bad?
The patch LED is also called SMD LED. Its principle of luminescence is to pass the current through the compound semiconductor. Through the combination of the electron and the hole, the excess energy will be released in the form of light to achieve the effect of luminescence.
Q:Patch LED beads can be bought in what place?
If you don't want to constantly change with it, suggest you go to OSRAM, Nichia, Corey, Taiwan Tongjia enterprise authorized agency purchase.
Q:Welding method and notice of SMT LED
I recommend reflow soldering under normal conditions and manual welding only when repaired. 2 manual soldering electric soldering iron maximum power can not exceed 30W, welding temperature is controlled within 300 degrees, welding time less than 3 seconds. 3 do not touch the colloidal iron welding head. 4 when the pin is heated to 85 degrees centigrade or higher than this temperature, it can not be pressed. Otherwise, the welding will be broken.
