SMD LED is a high-brightness light-emitting diode, its low heat, high brightness, sturdiness and durability is widely used in urban projects, large-screen display systems, audio-visual equipment, electronic dictionaries, LCD backlight, automotive instrumentation, automotive instrumentation, outdoor kanban and other products.
SMD LED is a kind of LED components, and plug-in LED is different from only the package form, it has a smaller volume, better controllability, luminous angle is also greater, SMD LED it has a good controllability, blue-jin photoelectric can be used in different semiconductor materials to produce different light-emitting color led, and through the fluorescent powder, SMD LED process color and other ways to finally get a variety of visible light.
Use of SMD LED:
Since the SMD led popular, gradually preempted the plug-in led market, SMD LED's main use distribution in 6 of LED application market.
1, LED display, the last century 90 's, LED technology leaps and bounds, LED display rapidly open up the market, Blue led appearance, LED display into the Full-color era, today, outdoor LED display everywhere, become a bright figure in the advertising industry.
2, car lighting, super bright LED can be made into a car brake lights, taillights and directional lights, can also be used for instrument lighting and interior lighting, SMD LED it has a distinct advantage over incandescent lamps in vibration resistance, power saving, and long-life. Used as a brake light, it has a response time of 60ns, much shorter than the 140ms of the incandescent lamp, and on a typical freeway, SMD LED it increases the safe distance of the 4-6m. LED as a recognized, low-carbon environmental protection of the typical representative, low voltage and high light efficiency features, so that it quickly become the field of automotive lighting darlings, thus forming Bai, and even Chi market demand, LED automotive lighting market prospects.
3, LCD backlight, LED as LCD backlight, it can not only as green, red, blue, white, SMD LED but also as a color backlight, many products have entered the production and application stage. Recently, the mobile phone on the LCD screen led to make backlight, improve the product grade, the effect is very good. The backlight of 15in (1in≈2.5cm) LCD screen made of 8 blue, 24 green, 32 red bosmfc-led, can reach 120W, $number lm, Brightness 18000nits ($literal). 22 LCD backlight has also been made, only 6mm thick, not only a good color mixing effect, SMD LED color index also reached more than 80. At present, large backlight is in the development stage, but the potential is great.
4, lighting, SMD LED due to the increase in brightness and price of light-emitting diode, coupled with long life, energy-saving, drive and control is simpler than neon, not only can blink, but also color, so with ultra-high brightness led made of monochrome, SMD LED multi-color and even discoloration of the light-emitting column with other shapes of various colored light-emitting units, decorative high-rise buildings, bridges, streets and squares and other landscape works well, showing a faction of colorful, starlight flashing and streamer splendor of the scene. There are many units to produce LED light beam up to more than million meters, Lights tens of thousands of, LED lighting set up the city's embellishment.
SMD LED Advantages:
1, small size: SMD LED is basically a small chip is encapsulated in the epoxy resin inside, very small, convenient for a variety of light source equipment design.
2, Pure color: SMD LED light color pure, soft, no glare, suitable for buildings, homes, shopping malls, banks, guesthouses, hotels, all kinds of public fields to do decorative lighting, add city color.
3, low heat: Single SMD LED power is very low, generally 0.04~0.08W, and light efficiency, so the calorific value is not high. Therefore, LED lamps and lanterns can be used as decorative lighting in the aquarium, and not produce a lot of heat caused by water temperature rise, SMD LED affecting the growth of ornamental fish.
4, energy-saving: light efficiency, low calorific value to create led components of the super energy-saving, LED lamps compared to traditional lighting and decorative lamps, LED lighting power is several times lower, but the effect is still high.
5, Controllability is strong: SMD LED color can almost cover the entire spectrum, the reaction speed is fast, at the same time has a strong controllability, SMD LED can use control system for all kinds of control it is different from other light source of the salient characteristics.
6, environmental protection: LED soft lamp composition of the material whether led or FPC, its material is the use of environmentally friendly materials, belong to recyclable type, not because of a large number of use caused by environmental pollution and destruction.
7, low demand: SMD LED voltage is very low, can be a few number of light source with a linear constant-current driver can be perfect to achieve efficient and safe and stable led work.
8, fast response: Blue-jin SMD led no need to warm the lamp time, sensitivity about 10^-9 seconds, so that it can be used in a variety of high-precision testing equipment.
9, sturdiness and durability: LED is fully encapsulated inside the epoxy resin, stronger than bulbs and fluorescent tubes. The lamp body also does not loosen the part, causes the LED not to be easy to damage.
10, long life: LED lamp normal service life is $number million hours, 24 hours a day non-stop work, its life expectancy nearly 10 years. As a result, the life expectancy of LED lamps is several times that of traditional lamps.
11, low radiation: no ultraviolet and infra-red in the spectrum, no heat, no radiation, small glare, cold light source, can be safely touched, belonging to the typical green light source.
SMD LED Features:
1, can be arbitrarily curved, can be fixed at any concave surface;
2, every 3 ledled supplier lamp can form a circuit;
3, small size, rich color;
4, each three LEDs can be arbitrarily truncated along the above tangent, SMD LED without damaging the other parts;
5, by the printed circuit board printed circuit board suppliers, back with double-sided adhesive, used for product fixed;
6, can achieve chasing, scanning, font, animation and other changes;
Characteristics of SMD LED
① luminescence principle is a cold glow, rather than by heating or discharge luminous, so the component life than tungsten bubble length about $number times, about 100,000 hours.
② does not need to warm the lamp time, the light response speed is faster than the General Electric lamp (about 3 ~ 400ns).
The ③ electro-optic conversion efficiency is high, the electricity consumption is small, compared to the bulb province about 1/3 ~ 1/20 energy consumption.
⑤ has good shock resistance, high reliability and low system running cost.
⑥ easy to small, thin, lightweight, no shape restrictions, easy to make all kinds of applications.
