Yunanengji The luminescence principle of colorful LEDs is as follows: To understand the luminescence principle of colorful LEDs, we must first understand the three primary colors of red (R), green (G), and blue (B). These three colors can be combined to obtain other different colors.
Masalan, when red light and green light are lit at the same time, red and green light are mixed into yellow. The color-changing principle of color-changing lamps is that when two LEDs are lit by three primary color LEDs respectively, yellow, purple, and cyan can be emitted (for example, purple light is emitted when red and blue LEDs are lit). If red, green, and blue LEDs are lit at the same time, white light will be produced.
If there is a circuit that can make red, green, and blue LEDs light up in pairs, light up individually, va uchta asosiy rangli LEDni bir vaqtning o'zida yoritadi, yetti xil yorug'lik rangi chiqarilishi mumkin, shunday qilib, rangli LED chiroqlar hodisasi paydo bo'ladi. Ularning turli superpozitsiya nisbatlari sababli, turli ranglar ishlab chiqariladi.
Rangli LEDlar keng qo'llaniladi. Rangli LEDlar turli yorug'liklarni chiqarishi va davriy bo'lishi mumkin, ular ko'pincha reklama belgilarida ishlatiladi, yorug'lik qutisi orqa chiroqlari, nuqta yorug'lik manbalari, yoritish mahsulotlari, elektron asboblar, mebel bezagi, o'yinchoqlar va sovg'alar, va hokazo.
