Q:What is patch LED?
Patch LED refers to surface mount LED.The LED is separated from the PCB board in the form of inline and surface mount. Piranha, 3mm lights, and 5mm lights are all pins. While most high-power LED is surface mount, that is, patches. Small power LED also has the form of surface mount such as PLCC-2 and PLCC-4.
Q:SMD LED lamp working voltage?
LED is a light emitting device of low voltage, low current, low power forward current general patch type LED when using (IF) 20MA, (VF) 1.8-2.5V, voltage of red green and blue (VF) voltage is 3.0-3.6V. Different manufacturers also have small differences, so first of all, look at the color,Of course. The multi chip assembly in high voltage chip together, some current: 1 watts, 1 watts and above. A wide variety of varieties, as follows:
Q:How many volts is a single LED on the LED patch band?
LED patch lamp is made of FPC circuit board, LED lamp and high quality silica gel sleeve. Waterproof performance, using low voltage DC power supply is safe and convenient, light colors, bright colors; outdoor use can be anti UV aging, yellowing, high temperature resistance and other advantages, the products are widely used in building lights, decorative lighting, advertising and entertainment quasi decorative lighting lighting field.
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 patches have several ways of welding. Which ones can be reflow? What can be done by eutectic welding? Is the welding of viscose and lens material is required?
L electrode for eutectic solder reflow, the other can be used, regardless of the kind of welding, the temperature is not lower than 100 degrees, the flammable soluble materials have strict requirements, depending on whether the welding temperature is lower than the melting point of what you said or. Otherwise, there will be deformation or damage to the material in the reflow process.
Q:LED package and LED SMD LED lamp, what is the difference? Will the release agent be used in that part?
Packaging is for TOP series LED, that is, the type of plastic molding. The patch is based on the PCB circuit board for molding. Mold release agent is used in molding.
Q:What are the storage requirements of SMT patch LED (LED)?
Keep in storage- the original sealing bag packing in the condition of the <40 C and <90% RH degrees for 12 months, more than the storage period will bake.Please check the leak before opening the packing bagIn opening the sealed bag, should be placed in SMD LED and C 60%RH. < < 30 degrees under the conditions in the above conditions, SMD LED must be in the open package using reflow within 24 hours. If placed more than 24 hours, you need to bake- baked, SMD LED in C + 80 degrees 5 degrees C and <=10%RH relative humidity in the oven for 24 hours• remove the pouch before baking, and do not open the oven door frequently
Q:How to detect LED SMD beads
Resistance voltage ordinary pointer table 1.5V in general, and some only in the high resistance file (*10K file) with 9V or 15V battery, so the pointer table to measure LeD beads to hit the highest resistance profile measurement, otherwise useless, of course, at this time the brightness is very small, can not see, can only to judge the positive and negative resistance values see.
Q:Patch LED manual welding, how can welding not burn lights?
When soldering, the temperature is best to be lower, and the average welding temperature is about 360. That's enough, because the melting temperature of the tin wire is about 220 degrees, so if it is allowed, the temperature can be reduced as low as possible.
Q:Patch LED features
The seismic resistance, high reliability, low operation cost system.It is easy to small, thin, lightweight, easy to shape without restrictions, made all kinds of application.
