Shenzhen Sunrise Optoelectronics Technology is located in Pinghu, Shenzhen, is a LED display manufacturer, the factory covers an area of 12,000 square meters, with advanced production equipment, gathering manufacturing and sales as one, the main business: fixed LED display, medical cross LED display, stadium LED display, lease LED display, car LED display, etc. Transparent LED display.
The outdoor LED display signs
are faced with the following problems before installation and use. These problems must be dealt with in order to run safely.
First, the LED display logo may be subjected to strong lightning and strong magnetic attack caused by lightning.
Two, the environmental temperature varies greatly. Outdoor LED display signs
work itself to produce a certain amount of heat, if the ambient temperature is too high and heat dissipation is not good, integrated circuits may not work properly, or even be burned down, so that the display system can not work properly.
Third, LED display signs installed in the outdoor, often sunlight, rain, wind dust cover, poor working environment. Wetting or serious dampness of electronic equipment can cause short circuit or even fire, causing failure or even fire, causing losses.
Fourth, the outdoor LED display signs, wide audience, visual distance, wide vision requirements; environmental light changes greatly, especially may be directly sunlight.
Above is the special requirements of the outdoor LED display signs, in view of these characteristics, the following sunrise ?Xiaobian (www.sunriseleddisplay.com) to summarize the outdoor LED display screen logo a few points for attention.
1.The LED display screen
and the combination of the screen and the building must be strictly waterproof and leak-proof; the screen should have good drainage measures, once water can be discharged smoothly.
2, install lightning arresters on LED screens and buildings. The main body and the outer shell of the display screen are well grounded, and the grounding resistance is less than 3 ohms, so that the large current caused by lightning can be released in time.
3, install ventilation equipment to cool down, so that the outdoor LED display
temperature is between -10 and 40 degrees. Axial fan is installed above the screen to discharge heat.
4.Choose industrial-grade IC chips whose working temperature is between - 40 ~80 ~C to prevent the LED display from starting when the temperature is too low in winter.
5.In order to ensure long-distance visibility under strong ambient light, the outdoor LED display must choose ultra-high brightness LED.
6.The display medium of LED display screen is a new type of wide-angle tube. It has wide viewing angle, pure color, consistent and coordinated, and its service life exceeds 100,000 hours. Display media packaging is currently the most popular square cylinder with shielding edges, silicone seals, non-metallized assembly; its exquisite appearance, solid and durable, with direct sunlight, dust, waterproof, high temperature, short circuit protection features of the "Five Prevention".
Deal with the above questions, your outdoor LED display logo is safe.
