PCR light source
PCR light source:For the irradiation end of the rapid PCR instrument, if the diameter of 5/8/10mm in-line LED is used, the optical path is shown in Figure 1 after optimized design. The light emitted by the in-line LED is first collimated by a plano-convex glass lens, and then passed through a tape Filter the light through the filter, and finally condense the light into the fiber through a glass spherical lens. Plano-convex glass lens and filter, glass ball lens fiber pass light, numerical aperture NA = 0.56. Separation between filter and glass ball lens = 3-5mm. The light spot at the end face of the fiber is shown in Figure 2. ZEMAX simulation found that the energy utilization rate of light is about 25.658%, compared with the packaged SMD LED (the energy utilization rate of light is about 85%)
4040 LED
Product Features Compact Right Angle PLCC-2 package 4.0 x 3.6 x 4.0 mm (LxWxH) Compatible with automatic placement equipments Moisture Sensitivity level: 3 RoHS compliant
3528 LEDs
Queendom monochromatic SMD LEDs are available in SMD LED, 3528 led, led3528, led datasheet with regular brightness and high brightness. hey are packaged with AlGaAs, AlInGaP and InGaN chips provided by well-known chip manufacturers, with complete colors.
5050RGB-4 Pin RGB LEDs
The control circuit and the RGB chip are integrated in a 5050 packaged component to form a complete external control pixel. Built-in signal shaping circuit, any pixel point receives the signal after waveform shaping and then output, to ensure that the line waveform distortion will not accumulate. Built-in power-on reset and power-down reset circuits.
 PLCC-4 package.  Intelligent reverse connect protection, the power supply reverse connection does not damage the IC.  The control circuit and the LED share the only power source.  Control circuit and RGB chip are integrated in a package of 5050 components, form a complete control of pixel point.  Built-in signal reshaping circuit, after wave reshaping to the next driver, ensure wave-form distortion not accumulate.  Built-in electric reset circuit and power lost reset circuit.

3W high power infrared LED
The effect is related to the angle of the infrareddiode, the number of light groups, the board, and the lens. The infrared camerais designed to use a larger-angle IR transmitter tube when the distance iscloser, and it must match the angle of view of the lens; For those above 20 meters, Taiwanese positive 12milor above chips must be used, and Japanese ones are also acceptable
1W High Power infrared  LED's
characteristic 1. Remote control sensor, concealed infraredsurveillance camera, infrared supplement light emitting tube, householdappliances, 3C digital products, lighting, gift toys, traffic signalapplications, communication product applications, etc. 2. Infrared emission tube (infrared lamp tube) canbe widely used in infrared cameras, audio output and other infrared referenceproducts. The power of the chip inside usually determines the emissiondistance, but infrared surveillance cameras
