]]> LED-Selection-Guide http://www.led-display.cc/LED-Selection-Guide/ 7-Segment-LED-Display Seven-segment LED display is a form of electronic display device for displaying decimal numerals that is an alternative to the more complex dot-matrix led displays. Seven-segment led displays are widely used in digital clocks, electronic meters, and other electronic devices for displaying numerical information.]]> http://www.led-display.cc/7-Segment-LED-Display/ 14-Segment-LED-display
A 14-segment led display is a led component based on 14 segments that can be turned on or off according to the graphic pattern to be produced. It is an extension of the more common seven-segment led display, having an additional four diagonal and two vertical segments with the middle horizontal segment broken in half.
]]> http://www.led-display.cc/14-Segment-LED-display/ 16-Segment-LED-Display A sixteen-segment display is a type of led display based on 16 segments that can be turned on or off according to the graphic pattern to be produced. It is an extension of the more common seven-segment led display, adding four diagonal and two vertical segments and splitting the three horizontal segments in half.]]> http://www.led-display.cc/16-Segment-LED-Display/ Special-LED-Display http://www.led-display.cc/Special-LED-Display/ Special-LED-Display Special led displays include 5 digits led display, 6 digits led display, 5 segment led display, 9 segment led display and other irrugular led display.

 

 

]]> http://www.led-display.cc/Special-LED-Display/ LED-Dot-Matrix Our LED dot matrix is a through-hole LED component. Usuall there are 5x7 LED matrix, 5x8 LED matrix and 8x8 LED matrix. The dots are round and seldom sqaure. Most of them are for indoor use. But some which are made from lamp type leds can be for outdoor use.

]]> http://www.led-display.cc/LED-Dot-Matrix/ LED-Light-Bar Bar graphs have 10 segment, 12 segment, 20 segment and other ones.

 

]]> http://www.led-display.cc/LED-Light-Bar/ Standard-LED       Standard led means the brightness is not very high in comparison with high-brightness led. It is used as a signal, for example in alarm item, it shows the running status. The requirements to standard led are relatively not high in current viewing angle and brightness. Usually standard leds are 3mm round led or 5mm round led, which can be various light emitting colors, such as: red, green, yellow, amber, blue and white.]]> http://www.led-display.cc/Standard-LED/ High-Brightness-LED Compared with standard led, high brightness led is a kind of high-intensity led, which requires high current and voltage to drive. Here we divide them into two types, super brightness led and ultra brightness led. Actually they do not have clear boundary between these two types of led. Generally, indoor use leds are super brightness leds and outdoor use leds to be ultra brightness leds.]]> http://www.led-display.cc/High-Brightness-LED/ Single-Digit-LED-Display Single digit  7-seg led display means there is only one digit can be displayed by this led display.

]]> http://www.led-display.cc/Single-Digit-LED-Display/ Dual-Digit-LED-Display Dual digit  7-seg led display means there are 2 digits can be displayed by this led display.

]]> http://www.led-display.cc/Dual-Digit-LED-Display/ Three-Digit-LED-Display Three digit  7-seg led display means there are 3 digits can be displayed by this led display. ]]> http://www.led-display.cc/Three-Digit-LED-Display/ Four-Digit-LED-Display Four digit  7-seg led display means there are 4 digits can be displayed by this led display.

 

]]> http://www.led-display.cc/Four-Digit-LED-Display/ Sighboard-oval-LED Signboard leds can be round, oval and even rectangular. But most oval leds are used as signboard leds. Oval led has two viewing angles, one is horizontal viewing angle and the other is vertical viewing angle.]]> http://www.led-display.cc/Sighboard-oval-LED/ Flahing-LED Flashing LED is also called blinking led. Flashing LED is like an ordinary led besides its IC which makes led flash in some frequency. It is usually used as a signal to draw peoples' attention. ]]> http://www.led-display.cc/Flahing-LED/ Traffic-LED Traffic leds are usually red, bluish-green and yellow leds. But traffic leds has the international-standard requirements for the color wavelengths. Traffic leds are round 5mm leds with small viewing angles.]]> http://www.led-display.cc/Traffic-LED/ White-LED There are two ways of producing high intensity white light using LEDs. One is to use individual LEDs that emit three primary colors red, green, and blue, and then mix all the colors to produce white light. The other is to use a phosphor material to convert monochromatic light from a blue or UV LED to broad-spectrum white light. RGB white led has rarely been used to mass produce white LEDs in the industry because of its high cost. But and our white led is made of blue led and yellow phosphor. White leds have warm white and cool white.]]> http://www.led-display.cc/White-LED/ SMD-LED SMD led stands for surface mounted device led which is also called surface mounted technology led (SMT led).
There are several advantages of SMD led over the older through-hole led.Fewer space needs when it is implemented.
Lower resistance and inductance at the connection (leading to better performance for high frequency parts).
Better mechanical performance under shake and vibration conditions.
Fewer unwanted RF signal effects in SMT parts when compared to leaded parts, yielding better predictability of component characteristics.
]]> http://www.led-display.cc/SMD-LED/ High-Power-LED High power LEDs (HPLED) can be driven at hundreds of mA (vs. tens of mA for other LEDs), some with more than one ampere of current, and give out large amounts of light. Since overheating is destructive, the HPLEDs must be highly efficient to minimize excess heat; furthermore, they are often mounted on a heat sink to allow for heat dissipation. If the heat from a HPLED is not removed, the device will burn out in seconds. High power leds are usually measured in watt. 0.5 watt, 1 watt, and 3 watt items are very common ones. But even higher watt items are available too.]]> http://www.led-display.cc/High-Power-LED/ Super-Flux-LED Unlike other leds, super flux led has 4 pins and which can have high power consumption and brightness efficiency. And it requires higher power supply both in voltage and current compared with standard and high-brightness leds.]]> http://www.led-display.cc/Super-Flux-LED/ Multi-color-LED Multi-color led as it name implies means single through-hole led can emit 2 colors or even more. Usually they are bi-color led, tri-color led, and RGB led.

Bi-color LEDs are actually two different LEDs in one package. It consists of two dies connected to the same two leads but in opposite directions. One led die can be lit at one time. Current flow in one direction produces one color, and current in the opposite direction produces the other color. But if both colors are lit in proper frequency, there will be a blended third color.

Tri-color LED is two LEDs in one case too, but the two LEDs are connected to separate leads. There are two leads control two colors respectively, and the third lead is the common anode or cathode lead. Having three leads is the most obvious difference of tri-color led from bi-color led.

A RGB LED has red, green and blue dies inside, generally using a four-wire connection with one common anode or cathode lead.

]]> http://www.led-display.cc/Multi-color-LED/ Infrared-LED Infrared led emits invisible infrared light which wavelength is below red wavelength. They are used for remote control, smoke detecting, night vision and so on.]]> http://www.led-display.cc/Infrared-LED/ 5*7-LED-Matrix 5*7 LED Matrix]]> http://www.led-display.cc/5*7-LED-Matrix/ 5*8-LED-Matrix 5*8 LED Matrix]]> http://www.led-display.cc/5*8-LED-Matrix/ 8*8-LED-Matrix 8*8 LED Matrix]]> http://www.led-display.cc/8*8-LED-Matrix/ Special-LED-Matrix http://www.led-display.cc/Special-LED-Matrix/ Photodiode-Silicon Photodiode silicon and infrared led can be a pair used in compact disc players, smoke detectors, and the receivers for remote controls in VCRs and televisions.]]> http://www.led-display.cc/Photodiode-Silicon/ LED-Application http://www.led-display.cc/LED-Application/ 5*8 LED Matrix - LM46058: 4.6 inch 5X8 single color LED dot matrix 2011-11-1
