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)

Do you understand the principle of LED light beads
Do you understand the principle of LED light beads
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.

What causes LED lights to flicker?
What causes LED lights to flicker?
Time of issue : 2022-06-08
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.

Have you ever understood what are the characteristics of led light-emitting diodes? I'll tell you. LED light characteristics: LED lights are light-emitting diodes, is the use of solid semiconductor chips for light-emitting materials, compared with traditional lamps and lanterns, LED lights energy saving, environmental protection, color rendering and good response speed.
(A) energy saving is the most prominent feature of LED lights In terms of energy consumption, the energy consumption of LED lights is one tenth of incandescent lamps, is a quarter of energy-saving lamps. This is one of the most important features of LED lights. Nowadays, people advocate energy saving and environmental protection, and it is because of this feature of energy saving that LED lights are widely used, making LED lights very popular. 
(B) can work in the high-speed switching state We usually walk on the road, will find that each LED composed of a screen or screen are unpredictable. This shows that LED lights can work at high speed switch. However, for our usual use of incandescent lamps, it can not reach such a working state. In ordinary life, if the number of switches is too much, will directly lead to incandescent filament breakage. This is also an important reason for the popularity of LED lights.
(C) environmental protection LED lights do not contain any mercury and other heavy metal materials inside, but fluorescent lamps contain, which reflects the characteristics of LED lights environmental protection. Nowadays, people attach great importance to environmental protection, so there will be more people willing to choose environmentally friendly LED lights.
(D) fast response speed LED lights also have a prominent feature, that is, the speed of response is relatively fast. As soon as the power is turned on, the LED lights will immediately light up. Compared to the energy-saving lamps we usually use, its response speed is faster, when turning on the traditional light bulb, it often takes a long time to light up the room, after the bulb is thoroughly heated up. 
(E) compared to other light sources, LED lights more "clean" The so-called "clean" does not refer to the surface of the lamp and the internal clean, but this light is a cold light source, will not produce too much heat, will not attract those insects like light and heat.
Especially in the summer, the rural insects will be particularly large. Some bugs like heat by nature, incandescent lamps and energy-saving lamps will produce heat after a period of time, this heat is just like bugs, it is easy to attract bugs to come. This will undoubtedly bring a lot of pollutants to the surface of the lamp, and, insect excrement will also make the room become very dirty. However, LED lights are cold light sources that do not attract bugs to them, so that they do not produce bug excrement. So, LED lights are more "clean".
