First, pins and packaging Generally, the infrared receiver has three pins: VCC power positive, GND power negative, and OUT output. Packaging usually includes iron shielding and epoxy plastic packaging, but the shapes are different, including chips, plug-ins, nose bridges, straw hats, cylinders, hemispheres, etc. Different manufacturers have different receiving head pin sequence and shell shape. Second, the main parameters of the infrared receiver The main parameters of the infrared receiv
Compared with traditional incandescent lamps, photodiodes have several advantages. First of all, the photodiode has no filament, which eliminates the possibility of burnout, so it has a longer service life. In addition, the small plastic bulb of the photodiode makes the photodiode more durable. Today's electronic circuits are also easier to use. The light-emitting process of conventional incandescent lamps contains a lot of heat, which is a waste of energy. If you don't use the lamp a
When the infrared receiving head emits infrared to control the controlled equipment, there are corresponding infrared photoelectric conversion elements in the controlled equipment, such as infrared receiving diode, infrared receiving head, photosensitive audio, etc. The appearance of conventional infrared LED beads is similar to ordinary LED beads, but they produce infrared rays. Usually the voltage is around 1.4V, and the working current is generally below 20 mA. In order to adapt to different
Let us take you to discuss how to choose a high-quality photodiode manufacturer. Many manufacturers of finished LED lamps are confused. In addition to choosing a good manufacturer, there is also the quality of the photodiode, which directly affects its life. First, look at the scale It is recommended that you choose a large-scale regular photodiode manufacturer and have the corresponding production qualifications to ensure the production of high-quality photodiode products. Second, look at
The current fluctuations of several milliamperes flowing through the light-emitting diode may have a great influence on the life and light attenuation of the light-emitting diode. Therefore, the current flowing through the light-emitting diode should be considered in the design. Many circuits powered by dry batteries usually cancel the current-limiting resistor RA, so that the light-emitting diodes work directly under the output voltage of the battery, and the current is limited by the interna
The harm of salt spray corrosion of LED lamp beads The salt spray corrosion of LED lamp beads will damage the metal protective layer, make it lose its decorativeness and reduce its mechanical strength. Some LED lamp bead electrical circuits are interrupted due to corrosion, especially in an environment with vibration.Factors affecting the results of the salt spray test of the LED lamp beads. When the salt spray of the LED lamp beads falls on the surface of the insulator, the surface resistance

When electrons and holes recombine, they can radiate visible light, so they can be used to make photodiodes. As an indicator light for circuits and instruments, or form a text or digital display. Gallium arsenide diodes are red, gallium phosphide diodes are green, silicon carbide diodes are yellow, and gallium nitride diodes are blue. Due to chemical properties, it can be divided into organic photodiodes and inorganic photodiodes. Photodiode is a commonly used light-emitting device, which emit
Light is a form of energy that can be released by atoms. It is composed of many small particles with energy and power but no mass. These particles are called photons and are the most basic unit of light. Photons are released by the movement of electrons. In an atom, electrons move in the form of orbits around the atom. Electrons have different energies in different orbital functions. Generally speaking, electrons with greater energy move away from the nucleus through orbits. When an electron

Infrared receivers are divided into level type and pulse type. The pulse type is mostly, and the level type is rare. level type, receiving continuous 38K signal, can output continuous low level, unlimited time. Its internal amplification and pulse shaping are directly coupled, so it can receive and output continuous signals. Pulse type can only receive intermittent 38K signals. If it receives a continuous 38K signal, it will remain high after a few hundred milliseconds, unless the distance
Photodiodes are semiconductor devices that convert electrical signals from light signals. The core part is a PN junction. Compared with ordinary diodes, the structure is different. The PN junction area is larger and the electrode area is smaller. The PN junction is generally very shallow, less than 1 micron. The work of photodiodes is started under reverse voltage. When there is no light, the reverse current generally does not exceed 0.1 microampere. This situation is called dark current. Whe
