Problems solved by technology

Similarly, it can be even more expensive to equip such powered devices with a digital data backhaul communication link
[0009] In addition, if the power receiving device is hardware connected to an external power source, the installation, emergency repair, service, maintenance, upgrade or replacement of such power receiving device is also an additional burden
For example, air quality sensors are laboriously installed on top of public utility poles, and even upgrading that sensor can be onerous, as it often requires someone with an electronics and / or telecommunications background to travel to each widespread installation to disconnect Hardware connects power and remote communication links, and reconnects newly upgraded sensors

Abstract

Power over Ethernet power sourcing device is provided inside a light fixture to enable a communications interface and provide electrical power to devices such as cameras, rain sensors, chemical sensors, wireless data uplink units, and other power over Ethernet powered devices. The power over Ethernet system is especially adapted for use in LED street lights and must be able to operate from a wide AC voltage supply range that is typically found in these types of lights.

Description

Background technique [0001] Broadly speaking, the present invention relates to street lighting, and by taking advantage of the ubiquitous availability of street lights, the advantage can be gained to support the operation of additional useful electronic equipment, such as traffic cameras, air quality monitoring devices and telecommunication transceivers. The present invention also relates to lighting devices, preferably lighting devices with solid-state lighting, preferably light-emitting diode lighting units (LEDs), and more particularly to solid-state lighting devices or devices comprising at least one Power over Ethernet (POE) power supply, the power supply The device may be used to provide power and data connections to one or more powered devices, which may be mounted inside or outside the lighting device, or located adjacent to the lighting device. [0002] The lighting device of the present invention is suitable for connection to any type of light source, including incan...
