What are the characteristics of SMD LED beads
What are the characteristics of SMD LED beads
The characteristics of SMD LED beads are these. SMD LED beads are divided into common brightness LEDs in accordance with the luminous intensity and operating current, and the luminous intensity between 10 and 100mcd is called high brightness SMD LED beads. Common SMD LED beads operating current, and low-current LED operating current of 2mA or less, SMD LED beads in the use of small size, long service life, low power consumption, high brightness, environmental protection, suitable for mass production, rugged and reliable, fast response, energy saving, shock resistance, shockproof, high resolution, can be designed and many other advantages. In the industrial field is now used in large quantities. Translated with www.DeepL.com/Translator (free version)

Speaking of LED beads believe that many people know what they are used for, LED beads, to put it bluntly, is a light-emitting diode made of semiconductor materials, in order to directly convert electrical energy into light energy, electrical signal into light signal light-emitting devices, SMD lamp beads in the use of the most important is heat dissipation, according to different manufacturers of lamp beads, with different packaging glue, pre-baking to pay attention to the time and temperature, and later to pay attention to SMD temperature, but many people do not know the principle of LED light-emitting beads, the following analysis of the principle of LED light-emitting beads for everyone.

What determines the light-emitting color of a light-emitting diode?
What determines the light-emitting color of a light-emitting diode?
What do you know about what determines the color of light-emitting diodes? Let me tell you. Light-emitting diodes are also known as led beads. Usually we see colorful light-emitting diodes, green, red, blue, purple, orange, yellow ...... Colorful, there are infrared and ultraviolet light. So, do you know what determines the different colors of light it emits? When an electron leaps from the conduction band to the valence band will radiate a photon, the energy of this photon E is equal to the forbidden band width Eg, and the wavelength of the photon λ = 1.24/Eg (μm), so the forbidden band width of the semiconductor basically determines the color of the diode light. Light-emitting diodes emit white light is not monochromatic light, but by a variety of light mixture. Common white light-emitting diodes using gallium nitride semiconductor material, its forbidden band width of about 3.39eV, the formation of the pn junction issued by the blue light (has been adjusted by impurity energy level photon energy). However, in the light-emitting diode pn junction outside coated with a layer of yellow phosphor, when the blue light hit the yellow phosphor, the light-emitting diode will issue a mixture of yellow and blue light from the white light.

During the process of capacitor charging, the lamp is off, and the lamp can be seen to be off with the naked eye because of the low current inside the capacitor, which leads to a slow charging rate. When the capacitor is fully charged, the electrical energy is released at once and the lamp will be lit. But because the stored electric energy is less, the electric light will go out soon, and keep charging and discharging repeatedly, and what you see with the naked eye, is the light flickering.

(Summary description)Have you ever understood how to buy led light beads? Let me tell you. Selection skills. 1, brightness LED brightness is different, the price is different. LEDs used in LED lamps and lanterns should meet the standard of laser class Ⅰ. 2, antistatic ability antistatic ability of LED, long life, and therefore high prices. Usually, LEDs with antistatic ability greater than 700V can be used in LED lighting. 3, wavelength wavelength consistent LED, consistent color, such as the requirement of consistent color, the price is high. No LED spectrophotometer manufacturers are difficult to produce pure color products. 4, leakage current LED is a one-way conductive luminous body, if there is a reverse current, it is called leakage, leakage current LED, short life, low price. 5, luminous angle Use of different LED luminous angle is not the same. Special light-emitting angle, the price is higher. Such as full diffuse angle, the price is higher.

5, luminous angle Use of different LED luminous angle is not the same. Special light-emitting angle, the price is higher. Such as full diffuse angle, the price is higher.
6, life The key to different quality is the life, life by the light decay decision. Light decay is small, long life, long life, high price.
7, the chip LED light-emitting body for the chip, different chips, the price varies greatly. Japan, the United States of chips more expensive, generally Taiwan and domestic chip prices are lower than Japan, the United States.
8, the chip size The size of the chip to the side length, the large chip LED quality is better than the small chip. Price is proportional to the size of the chip.
9, colloid The ordinary LED colloid is generally epoxy resin, with anti-UV and fire retardant LED more expensive, high-quality outdoor LED lighting should be anti-UV and fire.
