Description
Technical Field
The present invention relates to a lighting unit in an intelligent outdoor lighting network, in particular to a lighting unit for an outdoor lighting network.
Background
Digital lighting technology, i.e. lighting based on semiconductor light sources such as Light Emitting Diodes (LEDs), provides a viable alternative to conventional fluorescent, HID and incandescent lamps. Recent advances in LED technology have provided efficient and robust full spectrum illumination sources capable of achieving a variety of illumination effects in many applications. Some devices embodying these sources feature a lighting module that includes one or more LEDs capable of producing different colors, such as red, green, and basket, and a controller for independently controlling the outputs of the LEDs to produce various colors and color changing lighting effects.
Outdoor lighting, such as the illumination of roads, streets, parking lots, parks, scenic spots, sidewalks and bike tracks, is typically managed by a single regulatory agency. Centralized control by a management department allows for safer, more coordinated use and reduced maintenance costs. Currently most outdoor lights operate independently or in small groups powered by a common power source to enable timed control of the lighting system of a tile on and off.
New generation lights such as LEDs have the ability to adjust the lighting intensity level and color as desired. This allows additional flexibility in saving energy, reducing light pollution, and complying with local lighting regulations. But currently no control and management system is employed for outdoor lighting that can take advantage of this flexibility.
Current management systems contain specialized software tools that are not flexible enough and require extensive training to use, which results in significant costs. In many cases, the managed outdoor lighting network may include thousands of lighting units. In some cases the lighting units may be configured in groups, but this also generally does not adequately make the deployment manageable. Especially in China, various lighting networks such as oversized cities, large cities, medium and small cities and villages are respectively arranged, and the lighting networks of different types of cities have unique characteristics, but at present, large data collection, analysis and summarization of the lighting requirements of different types of cities cannot be realized, and unique lighting requirements are formed, furthermore, the lighting requirements of different areas of the oversized cities are different, and the current lighting management system cannot refine the requirements of different areas and perform lighting management according to local conditions.
The existing systems are also inflexible in terms of energy management. For example, solar street lamps have appeared, and new energy sources have been able to make outdoor light units self-sufficient in a part of areas, but as an entire system, energy sources cannot be allocated, and the situation of automatically sensing and adjusting the energy source supply of each lighting node through the system cannot be realized, so that the effect is poor in terms of energy saving.
The existing systems are also inflexible from the standpoint of device configuration, operation, and performance. The existing small number of interfaces of the control platform can only be controlled in a hundred flowers and are put together, unified standards are not realized, and a large number of lighting units, such as tens of thousands, can be deployed in the whole city under the condition of an outdoor lighting network. Currently, there is no convenient way to reconfigure the performance of a lighting system to meet new performance and operational requirements, and there is currently no convenient way to quickly replace consumable parts, resulting in inefficient replacement of the consumable parts.
