Currently, many LED companies, in order to get more profits in the fierce competition, their products in fact exist within a lot of problems. However the layman can not see any transmission of the disease of their products. Teach you how to distinguish good led lights & led COB display products, it need to reach these kinds of standards.
LED display on the ambient temperature is very picky. Theoretically at a room temperature of 25 ℃, the best of their work status. But actually, the outdoor display in the application ambient temperature is quite complicated, summer maximum temperature may be above 60 ℃, the lowest temperature in winter may be -20 ℃ below. LED, IC efficiency and performance are inconsistent brightness inconsistent display screen body as a whole will naturally become spent. Under different temperature conditions, the red, green, and blue three lamp brightness decay and fall is different, at 25 ℃, the white balance is normal, but at 60 ℃, three-color outdoor led lights brightness declined, and the attenuation values do not match, it will produce the entire screen brightness down and cast the phenomenon, will decline in the quality of the entire screen. The internal display Other positive efforts to the large number of improvements in aspects of the design, process, and can effectively control the temperature of the external environment on the ultimate effect of the display, as much as possible of the LED display can be in a variety of complicated conditions perfect display.
Power supply also affects the quality of an important part of an led lights display system. Power under different temperature conditions, the stability of their work, the output voltage value and with a load capacity will vary, because it is responsible for logistical role, its ability to protect the direct impact on the quality of the screen. Performance and stability, power supply prices of different brands and specifications are also considerable differences. Not just look at the low price without looking at the performance and quality to choose.
A well-known brands such as LED, is to go through the long-term market hard work to get recognized by the society. Enterprises depending on the brand for life and will never be easy for short-term interests and hurt their brand image.
