本发明涉及LED照明领域，尤其涉及一种智能化杀虫的LED路灯系统。The invention relates to the field of LED lighting, in particular to an intelligent insecticidal LED street lamp system.
背景技术Background technique
路灯是为人们提供夜间照明的重要设备，也用于为夜间汽车的出行提供方便。由于路灯使用数量众多，虽然单个路灯的耗电量有限，但是所有路灯的耗电量非常可观，如果都是使用市电供电，对市政管理部门造成巨大的运营成本，因此，路灯的制造厂商一直在寻找节能环保的路灯照明方案。Street lamps are important equipment for people to provide lighting at night, and are also used to facilitate the travel of cars at night. Due to the large number of street lamps used, although the power consumption of a single street lamp is limited, the power consumption of all street lamps is very considerable. If they are all powered by mains power, it will cause huge operating costs for the municipal management department. Therefore, street lamp manufacturers have been Looking for energy-saving and environmentally friendly street lighting solutions.
LED路灯具有环保无污染、耗电少、光效高、寿命长等特点，因此，LED路灯将成为节能改造的最佳选择。LED路灯与常规路灯不同的是，LED光源采用低压直流供电、由GaN基功率型蓝光LED与黄色合成的高效白光，具有高效、安全、节能、环保、寿命长、响应速度快、显色指数高等独特优点，可广泛应用于道路。LED street lamps have the characteristics of environmental protection, no pollution, low power consumption, high luminous efficiency, and long life. Therefore, LED street lamps will become the best choice for energy-saving renovation. The difference between LED street lamps and conventional street lamps is that the LED light source adopts low-voltage DC power supply, high-efficiency white light synthesized by GaN-based power blue LED and yellow, which has high efficiency, safety, energy saving, environmental protection, long life, fast response speed, and high color rendering index. With unique advantages, it can be widely used on roads.
然而，LED路灯一般建造在人行道旁边，与树木放置在一起，如果树木形成的树叶覆盖面积过大，不仅仅会影响LED路灯的照明效果，而且在LED路灯的长期照射下容易引起事故，例如，在秋天，如果LED路灯长期照射大量枯叶，很有可能引起火灾，以及如果因为某些原因，LED路灯存在一些暴露在外的电路线头，也可能点燃附近大面积的树叶，对LED路灯设备以及过往行人和车辆造成不利影响。However, LED street lights are generally built next to the sidewalk and placed together with trees. If the leaves covered by trees are too large, it will not only affect the lighting effect of LED street lights, but also easily cause accidents under the long-term irradiation of LED street lights. For example, In autumn, if the LED street light irradiates a large number of dead leaves for a long time, it is likely to cause a fire, and if for some reason, the LED street light has some exposed circuit wires, it may also ignite a large area of nearby leaves. Pedestrians and vehicles are adversely affected.
为此，本发明提出了一种智能化杀虫的LED路灯系统，能够对每一个LED路灯系统周围的树叶覆盖情况进行检测，以在检测出覆盖面积过大时，及时向相关管理部门发出报警，以便于相关管理部门采取相关措施，避免事故发生。For this reason, the present invention proposes an intelligent insecticidal LED street lamp system, which can detect the leaf coverage around each LED street lamp system, and send an alarm to the relevant management department in time when the coverage area is detected to be too large , so that relevant management departments can take relevant measures to avoid accidents.
