ENIKA electrical components Germany ENIKA model ENIKA price

ENIKA electrical components are devices for detachable (active) connection between optical fibers. They precisely align the end faces of two optical fibers to maximize the coupling of light energy from the transmitting fiber into the receiving fiber, while minimizing the impact on the system due to their insertion in the optical link. This is the basic requirement for fiber optic connectors. To a certain extent, fiber optic connectors affect the reliability and various performance characteristics of optical transmission systems.

ENIKA electrical components classification

Light-emitting diodes can also be divided into ordinary monochrome light-emitting diodes, high-brightness light-emitting diodes, ultra-high-brightness light-emitting diodes, color-changing light-emitting diodes, flashing light-emitting diodes, voltage-controlled light-emitting diodes, infrared light-emitting diodes, and negative-resistance light-emitting diodes. The control modes of LED include constant current and constant voltage. There are various dimming methods, such as analog dimming and PWM dimming. Most LED units adopt constant current control, which maintains stable LED current, makes it less susceptible to changes in VF, and extends the service life of LED luminaires.

ENIKA electrical components principle

Lasing principle of laser diodes: The P-N junction in a laser diode is formed by two doped gallium arsenide layers. It has a parallel-end structure, parallel to a mirror at one end (highly reflective surface) and a partially reflective surface at the other. The wavelength of the emitted light is directly related to the length of the junction. When the P-N junction is forward-biased by an external voltage source, electrons move through the junction and recombine as in ordinary diodes. When electrons recombine with holes, photons are released. These photons strike atoms, causing more photons to be released. As the forward bias current increases, more electrons enter the depletion region, resulting in the emission of more photons. Eventually, some photons drifting randomly within the depletion region strike the reflective surface perpendicularly and are reflected back along their original path. The reflected photons are again reflected back from the other end of the junction. This movement of photons from one end to the other occurs continuously multiple times. During photon movement, due to the avalanche effect, more atoms release more photons. This process of reflection and generation of increasing numbers of photons produces a very intense laser beam. Each photon generated in the emission process described above is identical to other photons in terms of energy level, phase relationship, and frequency. Therefore, the emission process yields a laser beam of a single wavelength. To generate a laser beam, the current of the laser diode must exceed a certain threshold level. Current below the threshold level forces the diode to behave as a LED, emitting incoherent light.

ENIKA electrical components parameters

Important aspects of the optical parameters of LED include: luminous flux, luminous efficacy, luminous intensity, light intensity distribution, and wavelength. 1. Luminous efficacy is the ratio of luminous flux to electrical power, with the unit generally being lm/W. Luminous efficacy represents the energy-saving characteristics of a light source and is an important indicator for measuring the performance of modern light sources. 2.LED Luminous intensity characterizes the strength of light emission in a specific direction. Since the light intensity of LED varies significantly at different spatial angles, we have studied the light intensity distribution characteristics of LED. This parameter has significant practical implications, directly affecting the minimum viewing angle of LED display devices. For example, in large-color LED displays in sports stadiums, if the selected LED single-tube distribution range is very narrow, viewers at larger angles relative to the display will see distorted images. Moreover, traffic sign lights also require recognition by people over a wide range. 9. Regarding the spectral characteristics of LED, we mainly examine whether its monochromaticity is excellent, and pay attention to whether the main colors such as red, yellow, blue, green, and white LED are pure. Because in many occasions, such as traffic signal lights, the requirements for color are quite strict. However, observations show that in some LED signal lights in China, the green appears bluish and the red appears deep red. From this phenomenon, it is very necessary and meaningful to conduct specialized research on the spectral characteristics of LED.
