Drawback is that greater volume than ordinary 5mmLED, angle at about 3045,60,90,120,140,160, no other point of view, full-color RGB mixing well, 5mm Hat LED well.

Piranha in the low power LED LED is the brightest, but brightness compared with high power 1W and 3W.5W, even if not much, Piranha LED is used most in advertising light module

Each LED has its own usefulness, not brightness, outsider is always better than brightness, my wife is the parameter ratio, consistency, with chips and so on.

NET lights and eyebrow lights on in the car, 10MM LED high power 1W LED or better, using small-angle, Piranha is no small point.

Use when you want to clean it, fixed on the bracket and LED chips in a bowl. Afterdrying welding poles LED chip and chip and out according to the size of the angleof light, choose the appropriate mode of grain. Fill in the die size plastic, Piranha LED chip welding inverted bracket alignment mode particle in die size. Stay dry (oven dry) after release. Cut it here and put it into the bars die down, followed by testing and sorting. Piranha LED specification LED with other package specification is the same. Multiple chip package in a Piranha bracket should take into account the thermal resistance, should try to reduce the thermal resistance in order to prolongthe service life.

Since the Piranha LED four feet, so in order to install the Piranha LED on the printed circuit board, on which there should be four holes. Since LED two electrodes connected on all four legs, two legs connected an electrode. Installation to confirm which of the two legs is positive, which two legs is negative, then the PCB design.

Piranha encapsulation mode particle shape is also varied, 3mm head and 5mm round head, flat shape of the concave shape. Light angle according to the requirements, you can choose from a variety of packaged die size.

As line contour light of the lamp is generally used as an urban high-rise buildings,and backlight advertising screens and large-font light is placed up high, if the LEDdoes not light or dark, its maintenance is very difficult. Because Piranha LED heat well, relatively ordinary LED 5mm, lumen maintenance, long life time, so the time youused, so you can save considerable maintenance costs.

Piranha LED can also be used to do the car’s brake lights, turn signals and reverselights. Because Piranha LED heat sink has the advantage, so affordable 70~80mA currents. In the exercise of the car, storage battery voltage fluctuations, especially when using the brake lights, current will suddenly increase, but it has much effect onPiranha LED, so it is widely used in the automotive lighting.

The second step: gum. Crystal wafer expansion will extend well into the shave on the silver-coated adhesive surface, silver on the back. Silver paste. Suitable for LEDchips in bulk. Dispenser the amount of paste on the PCB printed circuit boards.

Step three: put the prepared paste wafer expansion ring into thorn lattice, under the microscope by an operator LED chip Crystal pen with thorn thorns on the PCBprinted circuit boards.

Fourth step: thorn good Crystal PCB printed circuit board into the thermal cyclingoven thermostat can be replaced for a period of time, be the cured paste out (nolonger reset, or coating baked yellow LED chip, namely oxidation, cause difficultiesfor bonding). If the LED chip bonding, you need more than a few steps if only IC chip State rules to cancel the above steps.

Fifth step: Visco-chip. Dispensing machine in the PCB Board of IC position on the right amount of glue (or vinyl), and anti-static equipment (vacuum wand or child) put the IC die right in on a red plastic or vinyl.

The sixth step: drying. Taped naked in hot circulating oven is placed flat on the heating plate temperature can be replaced for some time, also cured naturally (a long time).

Seventh step: bonding (wire). Using aluminum wire welding machine will chip (grain or IC chip LED) and the corresponding pad on the PCB Board aluminum wire forbridge, COB of lead soldering.

Eighth step: pre-test. Use the detection tool (by COB have different equipment fordifferent purposes, simple is the high-precision power supply) testing COB plate, repair the unqualified Board back.

Nineth: dispensing. By dispensing the AB glue will mix a proper place of bondingwell LED on the grain, IC uses vinyl packaging and appearance packages according to customer requirements.

Tenth step: curing. Sealed gel PCB printed circuit board into the thermal cycling oven thermostat can be replaced on request different drying time can be set.

11th step: post-test. Will be packaged using dedicated PCB printed circuit board testing electrical performance testing tool, the bad quality.

This infrared to control the managed device, the control distance is proportional to the power. In order to increase the control distance of infrared, infrared light emitting diode operating in pulse mode, pulse of light (modulated light), the effectivetransmission distance is proportional to pulse peak current, just maximize peak Ip,you can increase the transmission distance of infrared light. Method for improvingthe Ip, is reducing the pulse duty cycle, pulse width t. Its frequency is below 300KHz.

High-Brightness LED is normal. According to normal diode current is 25 Ma, and each diode’s resistance to 128 euro for seven total resistance of the diode is 896 euros, seven diode voltage 3.2 times 7 is 22.4V,48 required less 22.4 equal to 25.6V. 25.6V divided by 1024 euro resistance derived from current 25 Ma. Seven highbrightness light emitting diode string joins 48 volt voltage resistor 1024-Europe.

2) Drives the low: use low voltage power supply led power supply voltages between 6-24V.

3) Applicability: small size, each led can be prepared into a variety of shapes, andsuitable for variable environments.

4) Environmental pollution: no harmful mercury.

In the architectural landscape lighting market, led are widely used, including architectural, interior decoration, tourist attractions such as, mainly used for important buildings, commercial centers, monuments, bridges, community, home, leisure andentertainment of the decorative lighting, set decoration and advertising of commercial lighting. In line with the high-tech Olympics and Green Olympics, people’s Olympics, Beijing has proposed an led as a light source should be used to beautify the capital at night.

COB light source can be simply understood as integrated high power source, according to product shape design light area and size of the light source.

Product features: cheap, easy

Electrical stability, optical design, circuit design, thermal design a scientific and reasonable;

Use of heat sink technology, ensure the heat flow out of the LED industry-leadingmaintenance rate (95%).

Quadratic optical matching of products, improve the quality of lighting.

High color, uniform light, without spot, and healthy environment.

Simple to install, easy to use, reduce the difficulty of lighting design, lighting process and subsequent maintenance cost savings.
