Q:What does patch LED light mean?
The patch may be said, adding that the patch board PCB light source, light source lamp light source generally refers to, patch may refer to the combination of PCB plate and two lens beads.
Q:SMD LED lamp working voltage?
Single chip of 1 watts, more than a lot, different colors, the voltage will be different. White is usually 3.0-3.6V.* in addition to their working voltage, working current is more important parameters, once the flow, it will burn out.The LED lamp. With chips is variety, many tricks, they can be connected in series and parallel. The voltage is divided into high voltage, low voltage and medium voltage
Q:Patch LED market conditions
Chinese suppliers also offer mature, but less profitable two-color and trichromatic products, which are mostly used in backlighting, appliances, consumer products, consumer electronics and display. Despite low market demand, vendors continue to offer sideview SMD LED, including 335 (4008), 020 (3806) and 215 (2810)
Q:How to detect LED SMD beads
The output voltage of the digital clock diode file is not high, generally below 2.5V, so the measurement of LED lamp does not work, the best way is to external electrical measurement. If there are a lot of beads to measure it, can take a constant current power measurement.
Q:The quality of the LED patch module
Quality of circuit board. In the same quality of LED, the quality of PCB will have an important impact on the life of LED. The circuit board is divided into aluminum plate, glass fiber board, semi glass fiber board and paperboard. The quality of aluminum is the best, the best cooling effect, but the cost is too high, the domestic manufacturers generally only in high-power LED products use, LED module manufacturers generally use cardboard, semi glass fiber and glass fiber board. Module, piranha, straw hat module monochrome is generally used in cardboard or semi glass, commonly used glass fiber or semi SMD glass fiber board. Colorful and full color module series generally at least half of glass fiber, so as to match.
Q:Patch LED light does not flash, why?
Are you saying that lamp is flashing? You can check the power output, according to your standard parameters and SMD beads, lamp panel series parallel mode, calculate the power output to output power of the test, you may be wrong, power, overload, but also the effective part of you may be the circuit for power transmission is not stable or low
Q:SMD LED specification
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: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.
Q:What is patch SMD-LED?
SMD LED is the surface mount light emitting diode. It is a solid state semiconductor device that converts electricity directly into light. The heart of LED is a semiconductor wafer, one end of which is attached to a bracket, one end is negative, and the other is connected to the positive electrode of the power to encapsulate the entire wafer with epoxy resin.
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?
To package with epoxy SMD beads are used in a lot of outdoor display, because the epoxy adhesive with good adhesion to all better PPI support in outdoor use, our high quality and inexpensive epoxy epoxy call for samples
