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?
Pressure drop does not mean good or bad, the greater the pressure drop, the better to choose the right for you
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: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:How does the LED patch lamp differentiate between positive and negative poles?
You can also use the ohmmeter's ohmmeter. To dial multimeter, to "ohm X1" file, the light emitting diode when the red pen is connected to the positive terminal of SMD LED, the black probe is connected to the negative terminal of SMD LED.
Q:Patch LED light does not flash, why?
Light emitting diodes, referred to as LED. Made from compounds containing gallium (Ga), arsenic (As), phosphorus (P), nitrogen (N) and so on.When electrons and holes are combined, they can radiate visible light, so they can be used to make light-emitting diodes. In circuits and instruments, as an indicator, or in combination with text or digital display. GaAs diodes glow diode gap, green silicon carbide, yellow light diode, light emitting diode gan. Because of the chemical properties and organic light-emitting diode OLED and inorganic light-emitting diode LED.
Q:Indoor full color LED display module and LED what is the difference between a full color?
(1): LED full color light emitting module display module is generally yellow green, pure green module price is more expensive; SMD full color LED display using pure green tube coreThe display module (2): LED full color pixel visual feeling is thick, low brightness, easy to have the mosaic phenomenon; patch LED full color consistent, high brightness;(3): maintenance module LED full color display is not easy to maintain, the whole module replacement cost is high; SMD full-color LED screen for easy maintenance, repair and replacement of single lamp;
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 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:Which is good for LED patch and LED bulb?
Chip LEDLED patch lamp (SMD) 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.LED bulbThe light emitting diode, is capable of converting electrical energy into visible solid semiconductor devices, which can be directly converted into electricity to light; LED Large Electronic = Display, LED = large electronic display; Lupus erythematosus disseminatus, systemic lupus erythematosus, a chronic idiopathic autoimmune disease; LED lead the past and past participle, meaning "leadership, led the Russian Pulkovo Airport IATA code.
