How Can Outdoor LED Displays Be Energy Efficient And Environmentally Friendly? -- A Case Study of Genesis II

As one of the most popular ways of outdoor advertising, outdoor LED displays have been widely used in a variety of public places. While it is getting increasingly popular, the bright light from the displays also have a detrimental impact on the cities. So, how can outdoor LED displays achieve energy efficiency and environmental protection? Let’s take Dakco’s Genesis II outdoor LED display as an example.

1) Adopt an auto dimming system that can adjust the brightness automatically.

The ambient brightness can be detected simply by installing a light sensor. The regulating system then automatically adjusts the brightness to appropriate level for the the surroundings. The display will be bright during the daytime when sunlight is strong. The screen will be dim when the light is faint at night.

2) Adopt a scientific circuit design

Although the LED display itself uses energy-saving light-emitting materials, outdoor LED displays are often larger in size, longer in service, which results in higher power consumption. A well-designed circuit might greatly improve the situation. While traditional common anode technology is more common, circuit using common cathode technology has been proven to have a perfecter performance. With common cathode technology, Genesis II uses less energy and create less heat, saving over 30%.

3) Adopt a well-thought-out thermal design

High RPM fans(maximum speed: 4000rpm) are integrated into the cabinets to remove heat. The cooling fans of Genesis II start working when the temperature hits 40℃to maintain thermal conditions and reduce failure risk. When the temperature drops to 35℃, it stops working. The control system makes sure that every use of electricity is at maximum efficiency. 

To summarize, by adopting an auto dimming system, a scientific circuit design and a well-considered thermal design, outdoor LED displays can be energy-saving and environmentally friendly. Genesis II is a perfevct outdoor LED display that can satisfy all.
