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)

What are the skills when buying LED lamp beads

Time of issue : 2022-06-09

LED beads are light-emitting diodes, which are often used in the commercial and home lighting industry to a class of decorative lighting products, which not only has the effect of lighting, and because of its soft light, used for indoor decoration, and because the type and type of LED beads on the market are very diverse, then consumers should pay attention to what details in the process of buying and selling. LED lamp beads purchase skills following these points.

Do you understand the principle of LED light beads

Time of issue : 2022-06-09

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?

Time of issue : 2022-06-09

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?

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.

(Summary description)Have you ever known what categories of led beads there are? Let me tell you. Category. 1, inline small power specifications are: straw hat / steel helmet, round head, concave, oval, square (2 * 3 * 4) bullet head, flat head, (3 / 5 / flat head / bread type) piranha, etc.. 2, SMD SMD is generally divided into (3020/3528/5050 these are front light) / 1016/1024, etc. These are side light sources. 3, high-power LEDs can not be classified to the SMD series, their power and current use are not the same, and the difference between the photoelectric parameters is huge. Single high-power LED light source such as not adding heat dissipation base (generally hexagonal aluminum seat), its appearance and ordinary SMD without much difference, high-power LED light source is round, the package is basically the same as SMD SMD, but with SMD SMD in the use of conditions / environment / effects have essential differences.
