TL;DR: In this paper, a lamp post monitoring and light controlling device of an energy-saving type street light and a security light which uses a Zigbee network is provided not only to perform functions that monitor and read a lamppost, but also to check electric energy which is consumed by each lamp post and to transmits information on the checked electric energy to a control center.
Abstract: PURPOSE: A lamp post monitoring and light controlling device of an energy-saving type street light and a security light which uses a Zigbee network is provided not only to perform functions that monitor and read a lamp post, but also to check electric energy which is consumed by each lamp post and to transmits information on the checked electric energy to a control center, thereby controlling the total power consumption of a street light including the power consumption of each lamp post. CONSTITUTION: A lamp post monitoring and light controlling device includes a lamp post controller(10) which is connected to a street light or a security light; a central control server(20); and a gateway(30) which is communicated through the medium of a central control server with the lamp post controller. The status information of a street light or a security light is transmitted through the gateway to the central control server. A control command, which is made by the central control server, is transmitted through the gateway to the lamp post controller for the control of the lamp post. [Reference numerals] (20) Central control server for street lamps; (30) Distribution board controller

TL;DR: In this article, a high effective solar street light is disclosed, which is an illumination device that is composed of a solar cell group, a storage cell groups, an illumination part, a structural part as well as a control circuit combination of charging and discharging control, light sensitive control, pedestrian detection control and timing control.
Abstract: A high effective solar street light is disclosed, which is an illumination device that is composed of a solar cell group, a storage cell group, an illumination part, a structural part as well as a control circuit combination of charging and discharging control, light sensitive control, pedestrian detection control and timing control, takes solar energy as resource and can operate independently outdoors. During the day, the solar cell group charges the storage cell group via the charging and discharging control circuit, at night, when no pedestrians pass by, the street light operates with lowerpower, only when a pedestrian passes by, the pedestrian detection control circuit output changes to cause the street light to operate with full power. The high effective solar street light has the beneficial effects of reducing electricity consumption of the street light, facilitating pedestrians at night, displaying a street light scene, and obviously improving efficiency of solar street light.

TL;DR: In this article, the authors proposed a utility model for an LED street lamp system using an Internet and a series radio-frequency network, which comprises a control center, at least one domain station and at least a way of LED street unit.
Abstract: The utility model relates to an LED street lamp system using an Internet and a series radio-frequency network, which comprises a control center, at least one domain station and at least one way of LED street lamp unit, wherein the control center is used for sending LED street light control instructions to the domain stations through the Internet and receiving supervision signals of one way of LED street lamp unit belonging to the domain station which are fed back by the domain station, and the one way of LED street lamp unit comprises at least one LED street lamp device; and the LED street lamp device is used for turning on or off LED lamps and adjusting the corresponding brightness according to the received control instructions and acquired light intensity. The system can integrally, partitionedly or independently control and supervise each street lamp of the whole city, districts and streets under the management of the control center, and can set the turning-on, turning-off and brightness adjustment of the street lamps in different periods of time so as to achieve the energy-saving effect, and simultaneously can supervise the operational state of each street lamp, and detect which street lamp has a fault and timely maintain the faulty street lamp so as to ensure road safety.
