The layout of the SMD LED industry chain in the United States

The United States has conducted deployment research on the upgrading of the SMD LED industry chain layout. In addition, in the SMD packaging field, the growth and form of any component supplied with fixed growth components according to the protocol are expected to increase to 95-85% of the low-temperature lamp bead market in SMD packaging within the next two years.

How to calculate the power of LED light emitting diodes based on the packaging size diagram of LED light emitting diodes? What are the usage conditions that LED light emitting diodes need to have in order to improve the rated efficiency of LED beads, and how to use them.

I am a professional manufacturer of LED LED products with excellent development, specializing in providing customers with environmentally friendly, energy-saving, long-life, and processing technology LED LED products. Our products have been supplied from countries and regions such as Europe, America, and Taiwan, gradually meeting market demand. From product customization to product development, the domestic LED packaging mass production has officially started.

Light emitting diodes can be divided into ordinary monochromatic light emitting diodes, high brightness light emitting diodes, color changing light emitting diodes, voltage controlled light emitting diodes, voltage drop light emitting diodes, ordinary light emitting diodes, deep light emitting diodes, white light emitting diodes, etc. according to the type of light emitted.

Ordinary monochromatic LED have advantages such as small size, low working voltage, high brightness, fast response speed, and long lifespan. They can be lit by various DC, AC, pulse power sources. It belongs to current controlled semiconductor devices, and suitable current limiting resistors need to be connected in series when used.

The emission color of ordinary monochromatic LED is related to the wavelength of the emission, which in turn depends on the semiconductor material used to manufacture the LED. The wavelength of red LED is generally 650-700nm, amber LED is generally 630-650nm, orange LED is generally 610-630nm, yellow LED is generally 585nm, and green LED is generally 555-570nm.

The commonly used domestic ordinary monochromatic LED include the BT (factory standard model) series, FG (ministerial standard model) series, and 2EF series. Commonly used imported ordinary monochromatic LED include SLR series and SLC series.

The semiconductor materials used in high brightness monochromatic LED and ultra-high brightness monochromatic LED are different from ordinary monochromatic LED, so the intensity of luminescence is also different. Usually, high brightness monochromatic LED are made using an arsenic aluminizer. As mercury is the negative electrode, dual color LED use phosphor materials from phosphorus and arsenide instruments. However, using phosphor materials cannot change its number and remaining electrical power.

The semiconductor materials used in high brightness monochromatic LED are different from ordinary monochromatic LED, so the intensity of light emission is also different. On weekdays, high brightness monochromatic LED are made using an arsenic aluminizer. Due to their high heat dissipation requirements, they are called high brightness monochromatic LED.
