In the busy streets of the city, outdoor display screens can be seen everywhere as important advertising carriers. They attract the attention of pedestrians with gorgeous pictures and dynamic displays, and convey rich business information to merchants. However, behind this, traditional outdoor display screens hide an increasingly prominent problem - the huge electricity bills caused by high energy consumption are quietly "stealing" your electricity bills.

Traditional outdoor display screens, such as common large light box advertisements, mostly use incandescent lamps and fluorescent lamps as light sources. These light sources have low luminous efficiency, and a large amount of electrical energy is wasted in the form of heat energy during the conversion into light energy. For example, a traditional light box with a large area can consume up to dozens of degrees of electricity per day. Although traditional outdoor LED display screens have made some progress compared to light boxes, they still have many problems in terms of energy consumption.

From the working principle point of view, the traditional outdoor LED display screen is composed of a large number of LED lamp beads. When the lamp beads emit light, part of the electrical energy is converted into heat energy, resulting in prominent heat dissipation problems. In order to ensure the normal operation of the display screen, it has to be equipped with a complex and high-energy cooling system, such as cooling fans, liquid cooling equipment, etc., which further aggravates energy consumption. A 100-square-meter traditional outdoor LED display screen has an average power consumption of at least 250W/㎡. If it runs 12 hours a day, 365 days a year, calculated at 1.3 yuan per kilowatt-hour, the electricity bill for the screen display alone exceeds 140,000 yuan a year (not counting the electricity bill of the heat dissipation equipment).

In addition, the power supply method of the traditional display screen is also unreasonable. Usually, a unified voltage of 5V is used to power all lamp beads. Some lamp beads actually only need 3V voltage to work normally. The excess voltage causes additional power loss and is converted into heat energy, which wastes energy and increases the heat dissipation burden. In the process of power conversion, the energy loss ratio of traditional power modules is as high as 10%-20%, and a large amount of power is lost in the conversion link.

Faced with the energy consumption dilemma of traditional outdoor display screens, outdoor LED advertising machines have become a reliable solution to reduce energy consumption and save electricity bills with advanced technology and innovative design. Outdoor LED advertising machines use LED light-emitting technology, which greatly improves the luminous efficiency. Compared with traditional light boxes, the power of outdoor LED advertising machines is only 1/3 - 1/5 of that of traditional light boxes under the same area. Taking a 10-square-meter LED advertising screen as an example, it works 12 hours a day on average and consumes only about 36 - 60 degrees of electricity. This is due to the fact that LED lamp beads can convert electrical energy into light energy more efficiently, reduce heat energy loss, and reduce energy consumption from the source.

Modern outdoor LED advertising machines are equipped with intelligent power management systems, which can provide fine power supply according to the actual needs of lamp beads. Through real-time monitoring of the working status of lamp beads, the system automatically adjusts the power supply voltage and current to ensure that each lamp bead can work under the best power conditions, avoiding the waste of power caused by excessive voltage in traditional power supply methods. This precise power supply method is like tailoring a "power package" for each lamp bead, which greatly improves the utilization rate of electricity and reduces unnecessary energy consumption.

The outdoor LED advertising machine is also equipped with a light sensing system that can automatically adjust the screen brightness according to the intensity of the ambient light. When the light is sufficient during the day, the screen automatically increases the brightness to ensure that the advertising content is clearly visible. When the light is dim at night, the screen brightness automatically decreases, which not only saves energy but also avoids light pollution to pedestrians. This adaptive adjustment function allows the advertising machine to maintain the best display effect in different environments while minimizing energy consumption. According to statistics, through the light sensing adjustment function, the outdoor LED advertising machine can save about 20%-30% of electricity.

In terms of heat dissipation, the outdoor LED advertising machine adopts an innovative heat dissipation design. On the one hand, the selection of lamp bead packaging materials and box materials with better heat dissipation, such as aluminum boxes, effectively improves the heat dissipation efficiency; on the other hand, the packaging technology is optimized so that the heat inside the display can be quickly dissipated. Good heat dissipation performance reduces the dependence on large heat dissipation equipment such as air conditioners and reduces additional power consumption. At the same time, due to the reduced heat generation, the aging speed of the electronic components of the display screen slows down, extending the service life of the equipment and further reducing the overall operating costs.

Some high-end outdoor LED advertising machines also have a variety of energy-saving modes. When the screen displays a large area of black or dark images, the system automatically reduces the current of the lamp beads and enters low-power mode. During non-peak hours, the screen can be set to reduce the brightness or sleep in some areas at regular intervals, so as to achieve deep energy saving without affecting the advertising display effect. These flexible and diverse energy-saving modes provide users with more personalized energy-saving options to meet the energy-saving needs in different scenarios.

LED advertising machines can display pictures and videos in a high-brightness, high-resolution and high-dynamic way, and can clearly present advertising content whether it is during direct sunlight during the day or at night with dark light. Its high color reproduction and strong contrast can vividly display advertising details, attract the attention of pedestrians, and enhance the communication effect of advertising. In shopping malls, transportation hubs and other places with large traffic, it can effectively improve the exposure and memory of advertisements. Traditional outdoor display screens often require manual operation to change advertising content, which consumes a lot of time and energy. Outdoor LED advertising machines can be remotely operated through the Internet and update advertising content anytime and anywhere. This not only saves labor costs, but also can timely adjust advertising strategies according to market changes and marketing needs, achieve precision marketing, and improve the return on investment of advertising.

In today's environment of advocating green and low-carbon, energy conservation and emission reduction, the high energy consumption of traditional outdoor display screens has become a bottleneck restricting its development. Outdoor LED advertising machines have become a reliable choice for solving the energy consumption problem of traditional outdoor display screens with their excellent energy-saving performance, excellent display effects, convenient content update methods and a wide range of application scenarios. Choosing outdoor LED advertising machines can not only save companies considerable electricity bills and reduce operating costs, but also keep up with the pace of the times, contribute to environmental protection, and achieve a win-win situation of economic and environmental benefits.
