What factors affect the brightness of LED words
LED light-emitting character because of its excellent transparency, excellent weather resistance, good processability and excellent comprehensive performance, non-toxic, and many other advantages, so the LED luminous word by market favour, but because of the service life of LED light-emitting character is limited, so luminous word daily maintenance is very important, most consumers know luminous word use bright color will darken after a period of time? How to solve similar problems to make a lot of consumers headache, luminous words today small make up and everyone to understand what factors affect the brightness of LED luminous words, how to solve?
The brightness of LED words is mainly affected by the following aspects:
I. the reasons affecting the brightness of LED luminous words are as follows:
1. Light absorption -- influence of LED and electrical devices inside the font on light;
2. LED quantity, type, light output, color, wavelength, and LED position in the light box;
3. Materials -- the transmittance, light reflection, light absorption and diffusion factors of the acrylic plates used;
4. Font size -- size, thickness of special light box and reflection factor of coating or other coating materials used inside the light box;
5, maintenance - light output intensity with the increase of service life of the influence of the internal accumulation of dust and font is abate, LED luminous words in acrylic and in most of the cost of light source, the lower the price, had to cut the sheet and the cost of light source, material decreased, the light transmittance of acrylic board, light reflection, light absorption and diffusion factor also fell.
Two, the light source fell, and then good plate also in vain. At the end of the dark, the final soft not dazzling! LED belongs to the luminescent body of the wafer. In a simple way, by applying constant pressure to the crystal, the molecules inside the crystal will drift and generate light energy. From this layer of principle, LED is a soft light source without flashing green environmental protection light. Luminous word itself is a kind of eye-catching signs. Bright, purity is tall, the colour of warm color attune is marked sex is tall, and the brightness that marked grade unit is illuminant. Yiyi believes that for the brightness of LED words, the most influential factor should be the number of acrylic sheets. Therefore, when choosing materials, merchants should not be greedy for small profits. In addition, the number of LED lights can be appropriately increased to improve the brightness of the words.
