Conrad Electronic SE electrical components are common light-emitting devices that emit light by releasing energy through the recombination of electrons and holes, and they are widely used in the lighting field. Light-emitting diodes can efficiently convert electrical energy into light energy and have extensive applications in modern society, such as in lighting, flat-panel displays, and medical devices. This electronic component first appeared in 1962, initially emitting only low-intensity red light. Later, versions emitting other monochromatic lights were developed, covering visible light, infrared, and ultraviolet spectra, with luminous intensity increased to a considerable level. Applications have expanded from initial uses as indicator lights and display panels; light-emitting diodes are abbreviated as LED. They are made from compounds containing gallium, arsenic, phosphorus, nitrogen, etc. When electrons and holes recombine, they radiate visible light, making them suitable for manufacturing light-emitting diodes. They serve as indicator lights in circuits and instruments or form character and numeric displays. Gallium arsenide diodes emit red light, gallium phosphide diodes emit green light, silicon carbide diodes emit yellow light, and gallium nitride diodes emit blue light. Based on chemical properties, they are divided into organic light-emitting diodes (OLED) and inorganic light-emitting diodes (LED). LED was initially used for indicative lighting in instruments and meters, later expanding to traffic signals, landscape lighting, automotive lighting, and mobile phone keypads and backlights. Later, new technology for micro-light-emitting diodes (micro-LED) was developed, significantly reducing the size of traditional light-emitting diodes. Arrays of independently emitting red, blue, and green micro-LEDs form display arrays for display technology applications. Micro-LEDs feature self-emissive display characteristics, offering higher efficiency, longer lifespan, and greater stability against environmental influences compared to self-emissive organic light-emitting diodes.

Conrad Electronic SE electrical component features

1. High sensitivity; 2. Geometric shape offers multi-faceted adaptability, allowing the manufacture of fiber optic sensors in any shape; 3. Capable of manufacturing devices that sense various physical information (sound, magnetism, temperature, rotation, etc.); 4. Suitable for high voltage, electrical noise, high temperature, corrosion, or other harsh environments; 8. And possesses inherent compatibility with fiber optic telemetry technology. The advantages of fiber optic sensors, compared to traditional sensors, include using light as the carrier of sensitive information and optical fiber as the medium for transmitting sensitive information. They possess the characteristics of fiber optics and optical measurement, offering a series of unique advantages. These include good electrical insulation, strong anti-electromagnetic interference capability, non-invasiveness, high sensitivity, ease of realizing long-distance monitoring of measured signals, corrosion resistance, explosion-proof properties, flexibility of the optical path, and ease of connection to computers. Sensors are developing towards greater sensitivity, precision, adaptability, compactness, and intelligence. They can act as human eyes and ears in places inaccessible to humans (such as high-temperature areas or zones harmful to humans, like nuclear radiation areas) and can even surpass human physiological limits by receiving external information imperceptible to human senses.

Conrad Electronic SE electrical component structure

The rated current of the fuse element is not equal to the rated current of the fuse. The rated current of the fuse element is selected based on the load current of the protected equipment. The rated current of the fuse should be greater than the rated current of the fuse element and determined in coordination with the main electrical appliance. The fuse mainly consists of 8 parts: the fuse element, the housing, and the support. The fuse element is the key component controlling the fusing characteristics. The material, dimensions, and shape of the fuse element determine the fusing characteristics. Fuse element materials are divided into two categories: low melting point and high melting point. Low melting point materials, such as lead and lead alloys, have low melting points and fuse easily. Due to their higher resistivity, they require larger cross-sectional dimensions when made into fuse elements. They generate more metal vapor during fusing and are only suitable for fuses with low breaking capacity. High melting point materials, such as copper and silver, have high melting points and do not fuse easily. However, due to their lower resistivity, they can be made with smaller cross-sectional dimensions than low melting point fuse elements. They generate less metal vapor during fusing and are suitable for fuses with high breaking capacity. The shape of the fuse element is divided into wire-shaped and strip-shaped. Changing the shape of the variable cross-section can significantly alter the fusing characteristics of the fuse. Fuses have various different fusing characteristic curves, suitable for the needs of different types of protected objects.

Conrad Electronic SE electrical component principles

A diesel engine drives the generator to operate, converting the energy of diesel into electrical energy. Inside the diesel engine cylinder, clean air filtered through the air filter mixes thoroughly with high-pressure atomized diesel injected by the fuel injector. Under the compression of the upward-moving piston, the volume decreases, and the temperature rises rapidly, reaching the ignition point of diesel. The diesel ignites, causing the mixed gas to burn violently. The volume expands rapidly, pushing the piston downward, known as 'work'. A gasoline engine drives the generator to operate, converting the energy of gasoline into electrical energy. Inside the gasoline engine cylinder, the mixed gas burns violently, the volume expands rapidly, and pushes the piston downward to perform work. Whether it is a diesel generator or a gasoline generator, each cylinder performs work in a certain sequence. The thrust acting on the piston is converted into force driving the crankshaft rotation via the connecting rod, thereby rotating the crankshaft. By installing a brushless synchronous AC generator coaxially with the power machine's crankshaft, the rotation of the power machine drives the rotor of the generator. Using the principle of 'electromagnetic induction', the generator outputs induced electromotive force, generating current through a closed load circuit.
