Cleverly Analyzing the Color Rendering of LED Beads.P2.5 indoor LED Display

　　As a traditional industry, the LED industry is deeply rooted in our daily lives. Many professionals, both inside and outside the industry, are familiar with it and even interested in some technical issues that they do not understand. Today, I will explain the color rendering in the LED bead technology index in simple and easy to understand terms. So what is color rendering? What is the color rendering property to distinguish? Please shift your gaze to the next line after all that time.

　　Color rendering refers to the degree to which the lighting source restores the surface color of the illuminated object. It is represented by the color rendering index Ra, which ranges from 0 to 100. The closer the Ra value is to 100, the higher the color rendering, and the better the color restoration of the illuminated object surface. The color rendering of the light source requires professional instrument testing. From the spectrum of the sun, it can be seen that the solar spectrum is the most abundant and the best color rendering light source. The color rendering performance of artificial light sources is always lower than that of sunlight. Therefore, the best way to distinguish the color rendering performance of artificial light sources is to compare it with sunlight. The simplest method is to compare the color of the palm or face of the hand under sunlight and artificial light sources. The closer the color is to sunlight, the better the color rendering performance. You can also point your palm towards the light source, If the color of the palm is gray or yellow, the color rendering is not good. If the color of the palm is red, the color rendering is normal. For LED light sources, Ra can be roughly divided into three levels: Ra less than 69, Ra between 70 and 79, and Ra greater than 80. For high-quality indoor lighting, light sources with Ra greater than 80 should be used.

　　If you want to purchase LED products with high color rendering performance in order to improve the color rendering of your face, I suggest that buyers undergo a color blindness test. People with color blindness cannot purchase lighting sources with high color rendering performance. Color blindness, also known as Dalton's disease, refers to the inability of the human eye to distinguish certain colors and the loss of color when seeing colored objects. Color blindness is more common in red green, while blue and panchromatic blindness are less common. When choosing lighting sources, first test yourself for color blindness, otherwise you won't be able to purchase high-quality lighting sources; When choosing lighting sources, we hope that the higher the color rendering, the better. However, the higher the color rendering, the lower the luminous efficiency and the higher the power consumption of the light source. For less important occasions, we can consider reducing the color rendering requirements, such as stairs and corridors. For LED light sources, LEDs with high color rendering also have high costs, and light sources with high color rendering have relatively good quality. Choosing LED light sources with high color rendering is also one of the simple methods to identify high-quality lighting products. Color rendering is an important indicator of lighting quality. A high color rendering lighting space can make people feel clear levels, colorful items, and achieve visual beauty.
