High brightness, low power consumption: Longcheng Optoelectronics creates outdoor energy-saving LED display screens
High brightness, low power consumption:
Longcheng Optoelectronics creates outdoor energy-saving LED display screens In the digital age, outdoor LED displays are an important part of urban lighting. Whether for commercial advertisements or public information dissemination, their application scenarios are very extensive. However, with the enhancement of environmental awareness and the increase in energy costs, how to achieve high brightness display effects while reducing power consumption has become a focus of concern for both LED display manufacturers and users. This article will deeply explore the technical paths for outdoor LED displays to achieve high brightness and low power consumption simultaneously, providing sustainable solutions for the industry.
Traditional outdoor LED displays often encounter high energy consumption issues when aiming for high brightness display. A medium-sized full-color LED display (about 50 square meters) consumes up to 30-50 kW of power at normal brightness, which is equivalent to the power consumption of dozens of household air conditioners operating simultaneously. This high energy consumption not only increases operating costs but also brings about significant environmental burdens.Brightness and power consumption are often positively correlated in traditional LED technology. To remain clearly visible under direct sunlight, outdoor LED displays typically need to reach a brightness level of 5000-8000 cd/m², which directly leads to a significant increase in energy consumption. How to find a balance between the two becomes the key to technological breakthroughs. Select high-efficiency LED chips The energy consumption of outdoor full-color displays mainly comes from LED chips. Choosing high-efficiency LED chips is the key to reducing the energy consumption of the display. Currently, there are mainly two types of LED chips on the market: traditional SIC LEDs and SMD LEDs. Compared with each other, SMD LEDs have higher brightness, lower power consumption, and better stability. Therefore, when designing outdoor full-color displays, SMD LEDs should be preferred. Optimize the driving circuit The driving circuit of outdoor full-color displays also has a significant impact on energy consumption. Optimizing the driving circuit can improve the efficiency of LED chips and reduce power consumption. Specific methods include: using high-efficiency driving ICs to reduce circuit losses; using dynamic scanning technology to improve display effect and reduce energy consumption. Improve optical design level The optical design of outdoor full-color displays has an important impact on energy consumption and display effect. By optimizing the optical design, the utilization rate of LED chips can be improved and the power consumption of the display can be reduced. Specific methods include: optimizing optical lenses to improve light efficiency; using reflective design to reduce light loss. Intelligent control system The intelligent control system of outdoor full-color displays can automatically adjust the brightness of the display based on monitoring of environmental light, temperature, etc., achieving the purpose of energy saving. The intelligent control system can also realize remote control, facilitating energy management by managers. Use energy-saving materials In the production process of outdoor full-color displays, using energy-saving materials is also an important means to reduce energy consumption. For example, using low-power LED chips, high-efficiency driving ICs, and high-quality optical lenses, etc.
The energy-saving technology for outdoor full-color displays requires us to start from every aspect and meticulously refine it in order to be achieved. This is similar to energy conservation and emission reduction in our daily lives, where we need to start from every detail in order to reach our overall goals. Therefore, when we are doing it, we must pay attention to the details and cannot ignore any single aspect. This is a long-term task that requires our continuous efforts to be accomplished.
