Street lighting is an essential service that provides safety, security, and visibility for motorists and pedestrians. However, not all street lights are created equal. Traditional lighting sources, such as incandescent, fluorescent, and high-pressure sodium lamps, suffer from lumen depreciation over time. This means that they gradually lose their brightness and efficiency, requiring more energy and maintenance to achieve the same level of illumination. Fortunately, there is a better alternative: LED street lights with constant lumen output (CLO) technology. CLO is a feature that enables LED fixtures to maintain a consistent level of brightness throughout their lifespan, regardless of environmental factors or aging. In this article, we will explore the advantages of Outdoor Street Lights with CLO and how they can benefit your community.
What is Constant Lumen Output?
Constant lumen output, or CLO, is a term that describes the ability of a light source to deliver a constant amount of light over its lifetime. Unlike traditional lighting sources, which experience a gradual decline in light output due to factors such as temperature, voltage fluctuations, dust accumulation, and lamp degradation, LED street lights with CLO can compensate for these effects and adjust their power consumption accordingly. This ensures that the street lights always provide the desired level of illumination, without compromising on quality or performance. How Does CLO Work?
CLO works by using a feedback mechanism that monitors the light output of the LED fixture and adjusts the power input accordingly. For example, if the LED fixture detects that its light output has decreased due to aging or environmental factors, it will increase its power input to compensate for the loss and maintain the target lumen output. Conversely, if the LED fixture detects that its light output has increased due to favorable conditions, it will decrease its power input to save energy and prevent overdriving the LEDs. CLO can be implemented in different ways, depending on the design and configuration of the LED fixture. Some common methods include: Using a built-in sensor that measures the light output of the LED fixture and sends a signal to the driver to adjust the power input. Using a pre-programmed driver that calculates the expected lumen depreciation of the LED fixture based on its operating hours and environmental conditions and adjusts the power input accordingly. Using a remote control system that communicates with the LED fixture and sends commands to adjust the power input based on the measured or estimated light output.
What are the Advantages of CLO?
CLO offers several advantages for outdoor street lighting applications, such as: Energy savings: CLO reduces the energy consumption of LED street lights by preventing overdriving or underdriving the LEDs. This means that the LED street lights only use the minimum amount of power required to achieve the target lumen output, resulting in lower electricity bills and carbon emissions. Maintenance savings: CLO extends the lifespan of LED street lights by preventing premature aging and degradation of the LEDs. This means that the LED street lights require less frequent replacement and maintenance, resulting in lower labor and material costs and less disruption to traffic and pedestrians. Uniformity and quality: CLO ensures that the LED street lights provide a uniform and consistent level of illumination across the road and sidewalk, without creating dark spots or glare. This means that the LED street lights improve the visual quality and comfort for motorists and pedestrians, as well as the safety and security of the area. Flexibility and adaptability: CLO allows the LED street lights to adapt to different scenarios and requirements, such as changing traffic patterns, weather conditions, or daylight hours. This means that the LED street lights can provide the optimal level of illumination for each situation, without wasting energy or compromising on performance. How to Choose LED Street Lights with CLO?
If you are interested in upgrading your outdoor street lighting system with LED street lights with CLO, there are some factors that you should consider, such as: The target lumen output: This is the amount of light that you want the LED street lights to provide, measured in lumens. The target lumen output depends on the type and function of the road, the pedestrian traffic, and the pavement material. You can consult the Illuminating Engineering Society`s recommended practice for the design and maintenance of roadway lighting (IES RP-8-18) for guidance on the appropriate lumen output for different applications . The expected lumen depreciation: This is the amount of light that the LED street lights will lose over time, measured in percentage. The expected lumen depreciation depends on the quality and design of the LED fixture, as well as the environmental and operating conditions. You can consult the manufacturer`s specifications and warranty for information on the expected lumen depreciation of the LED fixture. The CLO method and configuration: This is the way that the LED street lights implement and control the CLO feature, as described above. The CLO method and configuration affect the accuracy and reliability of the CLO feature, as well as the ease and cost of installation and maintenance. You can consult the manufacturer`s instructions and recommendations for the best CLO method and configuration for your LED fixture. Conclusion
LED street lights with CLO are a smart and sustainable choice for outdoor street lighting applications. They offer significant benefits in terms of energy savings, maintenance savings, uniformity and quality, flexibility and adaptability, and environmental friendliness. By choosing LED street lights with CLO, you can illuminate your streets with confidence and efficiency, and enhance the well-being and prosperity of your community.
