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:Is the forward voltage drop of the patch LED too large or too small?

Pressure drop does not mean good or bad, the greater the pressure drop, the better to choose the right for you

Q:What is the difference between patch LED beads and LED beads: General

A LED chip is led lamp. Common LED has two or four pins, and there is no needle foot, close to the circuit board, copper foil welding, are the same. You should choose the lamp the key is to consider the color temperature, color rendering index, light efficiency, light, and power quality, buy these things to buy better quality, common is topclass photoelectric

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:What is the difference in performance between the LED plug-in and the LED patch?

No difference, because the core of the two is the same, are diode PN junction, but no packaging, the production process is a little different

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: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:LED package and LED SMD LED lamp, what is the difference? Will the release agent be used in that part?

Mold release agent is a functional substance between the mold and the finished product. The release agent is chemically resistant and is not soluble in contact with the chemical constituents of different resins (especially styrene and amines). Release agent also has heat and stress properties, not easy to decompose or wear; release agent bonded to the mold, and not transferred to the processed parts, without prejudice to painting or other two processing operations. Because of the rapid development of injection molding, extrusion, calendering, molding and laminating, the dosage of mould release agent is greatly improved.

Q:Led lamp and Led patch two what is the difference between ah, the feeling is a patch of long service life, whether or not? 5-10 meters pan area lighting lamp selection Everbright shaped or patch shape?

First of all, I want to say, in the same light emitting chip case, two is not what were, just a different process is a DIP plugin, a SMD patch process, the 3 floor of the right, just some high grade patch.

Q:What are the storage requirements of SMT patch LED (LED)?

Moisture-proof packing- anti SMD LED in the transport and storage of moisture absorption, SMD LED shall be placed in sealed moisture-proof bag, inside put damp proof agent for protection, and placed the humidity humidity SMD display card packaging bag.
