ORGA lamp electrical components, German ORGA lamp models, ORGA lamp prices

ORGA lamp electrical components are parts that connect the battery to external conductors. In electrical engineering, terminals mostly refer to wiring ends, also called terminal blocks. Types include single-hole, double-hole, socket, hook, etc. By material, they are classified as silver-plated copper, galvanized copper, copper, aluminum, iron, etc. Their main function is to transmit electrical signals or conduct electricity. In engineering, they are interfaces reserved by pre-station works for post-station works, and are embedded facilities for post-station interface works. When observing objects with a terminal cross-section inspection microscope, it can produce an upright three-dimensional spatial image with strong stereoscopic effect, clear and wide imaging, and a long working distance; equipped with a high-precision harness terminal image measurement and analysis system, combined into a harness terminal inspection microscope, the perfect combination of a high-quality optical system and a high-resolution camera makes the cross-section image clearer, and the unique fixed magnification and fixed grade make measurements more precise. To detect whether the terminal crimping is good, professional testing equipment is required. Common terminal testing equipment includes: terminal cross-section analyzer.

ORGA lamp electrical component structure

Common electrodynamic cone paper loudspeakers. Electrodynamic cone loudspeakers were formerly known as paper cone loudspeakers; although the diaphragm is still mainly paper cone, many polymer material diaphragms and metal diaphragms have appeared, so the term cone loudspeaker is appropriate. Cone paper loudspeakers generally consist of three main parts: the magnetic circuit system (permanent magnet, core pole, magnetic plate), the vibration system (paper cone, voice coil), and the support auxiliary system (centering spider, basket, surround). 1. Voice coil: The voice coil is the drive unit of the cone paper loudspeaker. It is made of very fine copper wire wound in two layers on a paper tube, generally with dozens of turns, also called a coil, placed in the magnetic gap formed by the magnetic core pole and the magnetic plate. The voice coil is fixed to the paper cone. When the audio current signal is applied to the voice coil, the vibration of the voice coil drives the paper cone to vibrate. 2. Paper cone: There are many types of materials used for the cone diaphragm of cone paper loudspeakers, generally divided into natural fibers and synthetic fibers. Natural fibers often use cotton, wood, wool, silk, etc., while synthetic fibers use rayon, nylon, fiberglass, etc. Since the paper cone is the sound radiation device of the loudspeaker, it largely determines the sound performance of the loudspeaker. Therefore, regardless of the type of paper cone, it is required to be lightweight and have good rigidity, and must not deform due to changes in ambient temperature and humidity. 3. Surround: The surround is set to ensure the axial movement of the paper cone along the loudspeaker and restrict lateral movement, while also blocking the flow of air between the front and back of the paper cone. In addition to the materials commonly used for paper cones, the surround material also uses plastic, natural rubber, etc., which are thermally bonded to the paper cone. 4. Centering spider: The centering spider is used to support the joint area of the voice coil and the paper cone, ensuring it remains vertical and not skewed. The centering spider has many concentric rings, allowing the voice coil to move freely up and down in the magnetic gap without lateral movement, ensuring the voice coil does not touch the magnetic plate. The dust cap on the centering spider is to prevent external dust from falling into the magnetic gap, avoiding friction between dust and the voice coil, which would cause abnormal sounds from the loudspeaker. Generally, a loudspeaker is composed of: magnet, frame, centering spider, molded surround, and cone paper cone.

ORGA lamp electrical component parameters

(1) Nominal capacitance is the capacitance marked on the capacitor. However, there is a deviation between the actual capacitance of the capacitor and the nominal capacitance. The accuracy class corresponds to the allowable error. General capacitors commonly use classes I, II, and III, while electrolytic capacitors use classes IV, V, and VI to indicate capacitance accuracy, selected according to the application. The capacitance value of an electrolytic capacitor depends on the impedance presented when operating under AC voltage. The capacitance value changes with changes in operating frequency, temperature, voltage, and measurement method. The unit of capacitance is F (Farad). Since a capacitor is a "container" for storing charge, there is the issue of "capacity" size. To measure the ability of a capacitor to store charge, the physical quantity of capacitance is defined. A capacitor can only store charge under the action of an applied voltage. Different capacitors may store different amounts of charge under voltage action. Internationally, it is uniformly stipulated that when a DC voltage of 1 volts is applied to a capacitor, the amount of charge it can store is the capacitance of that capacitor (i.e., the charge per unit voltage), represented by the letter C. The basic unit of capacitance is the Farad (F). (2) Rated voltage is the maximum DC voltage that can be continuously applied to the capacitor at the minimum ambient temperature and rated ambient temperature. If the operating voltage exceeds the withstand voltage of the capacitor, the capacitor will break down, causing damage. In practice, as the temperature rises, the withstand voltage value will decrease. (3) Insulation resistance. When DC voltage is applied to a capacitor, leakage current is generated. The ratio of the two is called insulation resistance. When the capacitor is small, its value mainly depends on the surface state of the capacitor. Generally, the higher the insulation resistance, the better. (4) Loss. The energy consumed by heat generation per unit time under the action of an electric field is called loss. Loss is related to frequency range, dielectric, conductivity, resistance of the metal parts of the capacitor, etc. (6) Frequency characteristics. As the frequency increases, the capacitance of general capacitors shows a decreasing trend. When the capacitor operates below its resonant frequency, it behaves capacitively; when it exceeds its resonant frequency, it behaves inductively, at which point it is no longer a capacitor but an inductor. Therefore, it is essential to avoid operating the capacitor above its resonant frequency.

ORGA lamp electrical component classification

Thyristors have multiple classification methods: (1) Classification by turn-off, conduction, and control methods: Thyristors can be divided into ordinary thyristors, bidirectional thyristors, reverse-conducting thyristors, gate turn-off thyristors, BTG thyristors, temperature-controlled thyristors, and light-controlled thyristors, among others, based on their turn-off, conduction, and control methods. (2) Classification by pins and polarity: Thyristors can be divided into two-pin thyristors, three-pin thyristors, and four-pin thyristors based on their pins and polarity. (3) Classification by package form: Thyristors can be divided into three types based on their package form: metal-packaged thyristors, plastic-packaged thyristors, and ceramic-packaged thyristors. Among them, metal-packaged thyristors are further divided into bolt-type, flat-type, round-case type, etc.; plastic-packaged thyristors are divided into two types: with heat sink and without heat sink. (4) Classification by current capacity: Thyristors can be divided into high-power thyristors, medium-power thyristors, and low-power thyristors based on current capacity. Usually, high-power thyristors mostly adopt metal shell packaging, while medium and low-power thyristors mostly adopt plastic or ceramic packaging. (5) Classification by turn-off speed: Thyristors can be divided into ordinary thyristors and high-frequency (fast) thyristors based on their turn-off speed. (6) Zero-crossing triggering - generally for power regulation, i.e., triggering occurs when the phase of the sinusoidal AC voltage crosses zero. Triggering must occur at the zero-crossing point to conduct the thyristor. (7) Non-zero-crossing triggering - the thyristor can be triggered to conduct regardless of the phase of the AC voltage. Commonly, this is phase-shift triggering, i.e., changing the output percentage by changing the conduction angle (phase angle) of the sinusoidal AC voltage.
