SMD led characteristics

① Cold glow serves the principle is of light, rather than through heating and discharge luminescence, so about 50~100 times longer life than the tungsten lamp, about 100,000 hours.

② No warming lamps and light response speed faster than General Electric (~ 3 ~400ns).

③ Electro-optical conversion efficiency, low power consumption, energy consumption than the bulb about 1/3 ~ 1/20.

④ Excellent shock resistance, high reliability and low running costs of the system.

⑤ Is small, thin, lightweight, no shape limits, easy to make all kinds of applications.

Line type LED package takes the form of encapsulation. Potting process is LED before forming intraluminal injection of liquid epoxy resin, and then insert the weldingLED bracket, placed into the oven cured epoxy resin will be LED away from the cavity that is forming. Because the manufacturing process is relatively simple, low cost, has a high market share.

2. Damp-proof, in order to avoid moisture during transportation and storage, packaging is of the SMD LED with aluminum moisture-proof bags and packaging bagwith desiccant and humidity cards, mainly to control the bag of desiccant and humidity, humidity is aiming to monitor humidity in the bag.

3. Storage bag sealed storage conditions temperature < 40 ℃.

1, the solid Crystal: light grains by automatic machine crystalline solid to stand on,wafer through the glue at the bottom (including silver glue and Scotch tape).

2, wire: high precision wire bonders, chip electrodes and bracket with a purity of 99.99 gold link principle is ultrasonic welding.

3, glue: chip class through the laminator plastic cake moments through 170 high-temperature melting moments and solidification is attached to the surface and exposed to protect grain and gold from damage. Top class are dispensing technology,by dispensing droplets of glue onto the top led lamp Cup, through high temperature baking frozen, also aims to protect grain and gold.

4, dicing: above the material is arranged in one of hundreds of thousands of boards, need to cut into a single one is a finished product size.

5, light: material (grain size) are mixed together, so you need to test light to brightness differences between different product categories (this should be under the same type of the same color), splitting the main voltage test data, brightness, color temperature, wavelengths, whether leakage (leakage control 5 microamps). Light can appear many different stalls.

6, and packaging: posted tablets glow diode industry also will its called series with, is will a star star small of led into contains with Shang, usually put same color same voltage same brightness same wavelength of led packaging in with, General used rubber disc to mount with, so everyone see of are a volume a volume of, purpose is to in using Shi can through automatically posted tablets machine take material.

(2) According to the colors red, Orange, yellow, green and other types.

(3) In terms of structure, reflector, seven in a single-stage and single-chip integrated.

(4) The light from each electrode connection with common anode and two common cathode.

Industrial control equipment technology (oil and gas flow meter, for heavy-duty motor control technology and welding line with drive control panel)

Military applications (including aircraft, ground vehicles, GPS and radio system).

Equipment (including an oven, microwave and dishwasher displays).

Generally we use dot matrix display Chinese character is 16*16 in the lattice of song typeface library, known as 16*16, is a character in vertical and horizontal 16 shows in the region. That is with four 8*8 of the lattice into a 16*16 grid. Like to displayed “you” is corresponding of points points bright, due to lattice in column line Shang is low level effective, and row line Shang is high level effective, so to displayed “you” Word, is it of bit code information to take anti-, that all column (13~16 feet) sent (0xF7,0x7F), and first line (9 feet) sent 1 signal, then first line sent 0. Sending data to display the second row (13~16 feet) to (0xF7,0x7F), while the second (14 feet) to send 1 signal. And so on, as long as the interval is short enough to display per row, using human Visual suspensive effect, which sent data is scanned after the 16 # 16 you will see a “you”; the second method is the type of the data signal to line scan line is the same way. Same with “you” to explain, 16 rows (9, 14, 8, 12, 1, 7,2, 5), sent (, 0x00,0x00) and the first column (13 foot) delivery, “0”. Similarly scan the second column. When the line to send the 16 data lines after scanning 16 a “you” is displayed.

Ultra high density can be achieved: indoor up to 62.5 points/square meter (P4). Manufacturers can do to P3. Density required for better heat dissipation.

Mix well: using light-emitting devices their own micro-processing and the wave-particle duality of light, makes the Red particles, pure green light particles, Blu-ray three particles are fully mixed up with each other.

Environmental performance: wet, hot and cold resistance, high resistance to corrosion

Antistatic performance strong: production environment with strict standards and product structure design.

Viewing angle: 140 degrees (horizontal)

High permeability: a new generation of dot-matrix technology by virtue of its highdegree of purity, and epoxy resin material almost 100% light flux, reached near-perfect permeability.

2) Anti-static work area, the use of anti-static floor in the area, ESD workstation, anti-static ground leads, and anti-static devices, and the relative humidity at 40 per cent.

3) The harm caused by static electricity on electronic equipment may be released inany part of the equipment from the manufacturer to the wild. Harm because therewas no adequate, effective training and equipment caused by steering failure. LEDdevices are sensitive to static electricity. INGAN chips are generally considered tobe “first” are subject to interference. ALINGAP LEDS SHI “second” or better.

4) ESD damaged devices can display a Dim, fuzzy, out, short or low VF or VR. ESDdamage of equipment should not confuse overload, such as: due to faulty designor drive chip hook, cable shield ground or packaging, or general environment-induced stress.

5) Safety and ESD control program: very similar to most electronic and electro-optical company of ESD and have successfully realized the device’s ESD control, manipulation and the main program. These programs for ESD ancient has instrumentsused to detect quality results. ISO-9000 certification such as his normal control procedures.
