Description

[0001] POWER-SAVING MULTIFUNCTION OUTDOOR ILLUMINATOR [0002]

The present invention relates to an outdoor lighting device, and more particularly to a power saving multi-function outdoor lighting device.

Outdoor lighting devices, such as street lights or walking lights, are installed to illuminate the dark night, primarily to ensure the safety of pedestrians and vehicles. The outdoor lighting system is preferentially installed in dense areas, but its purpose is to provide safety for pedestrians and vehicles. Therefore, it can be said that the effect is greater in places where people are rarely used.

However, it is costly to install the outdoor lighting devices individually in a remote place where people are unfamiliar. A large proportion of these installation costs is to install a wired line such as a power supply line for power supply or a wired communication network for remote control when the lighting apparatus is placed in a required position. This is because, in the case of the wired line, the construction must be performed not only at the place where the lighting apparatus is disposed but also at other places. Recently, techniques such as individual power generation technology and wireless remote control technology have been introduced so that a wired line is not required for an outdoor lighting device.

However, since the amount of power generated by the self-generated power generation technique is not so large, there is a need to reduce the power consumption of the outdoor lighting device.

Hereinafter, the present invention will be described in detail with reference to the preferred embodiments of the present invention with reference to the accompanying drawings. However, the present invention can be implemented in various different forms, and is not limited to the embodiments described. In order to clearly describe the present invention, parts that are not related to the description are omitted, and the same reference numerals in the drawings denote the same members.

Throughout the specification, when an element is referred to as " including " an element, it does not exclude other elements unless specifically stated to the contrary. The terms "part", "unit", "module", "block", and the like described in the specification mean units for processing at least one function or operation, And a combination of software.

FIG. 1 shows the appearance of a power saving multi-function lighting device according to an embodiment of the present invention.

1, the power saving multi-function outdoor lighting apparatus of the present invention includes a support ST for supporting at least one lamp LP, a solar power generation module SM and a wind power generation module WM, At least one lamp (LP) for irradiating light according to control, a wind power generation module (WM) for performing wind power generation as a power supply means, a solar power generation module (SM) for performing solar power generation, a general connection terminal , A control unit (CT) for controlling at least one lamp (LP), a solar power generation module (SM), a wind power generation module (WM) and a universal connection terminal (PT).

The strut ST is utilized to dispose at least one lamp LP, a wind power generation module WM and a solar power generation module SM at predetermined predetermined heights, and a lighting device, such as a street lamp, Otherwise, it may be omitted. For example, when an outdoor lighting device is installed on a telephone pole or used for building landscaping, at least one lamp (LP), a wind power generation module (WM), and a solar power generation module (SM) Do.

The at least one lamp LP emits light under the control of the control unit CT and may be embodied as a halogen lamp, a metal halide lamp, a sodium lamp, or the like. Especially recently, LED lamps have been preferred to reduce power consumption, long lamp life, and low maintenance costs.

In the present invention, the amount of light irradiated by each of the at least one lamp (LP) under the control of the controller (CT) can be adjusted. That is, a dimming operation can be performed.

Wind power generation module (WM) and solar power generation module (SM) are eco-friendly power generation means for supplying electric power to outdoor lighting devices, so that outdoor lighting devices can function as lighting devices independently without additional wired power supply.

The wind power generation module (WM) includes a rotor rotating by wind force and a nacelle which converts the rotational force of the rotor into electrical energy, and converts wind power into electric energy to produce electric power for turning on the LED lamp. FIG. 1 shows an embodiment of the wind power generation module WM. However, it may be provided with a wind power generation module WM having a rotor blade, such as a conventional wind power generation module WM. Recently, the wind power generation module (WM) has been transformed into various forms considering the design. Accordingly, the shape of the wind power generation module (WM) can be variously changed.

The solar power generation module SM converts sunlight into electric energy including a plurality of solar cells that generate electric energy in response to incident sunlight when sunlight is incident. The photovoltaic power generation module (SM) can be implemented in various forms such as a wind power generation module (WM). In some cases, the photovoltaic generation module (SM) and the wind power generation module have.

The photovoltaic power generation module SM and the wind power generation module WM may be freely disposed in the strut ST but may be disposed at the top of the LED lamp LP as shown in FIG. This is to increase the power generation efficiency of the solar power generation module (SM) and the wind power generation module (WM).

The photovoltaic power generation module SM and the wind power generation module WM may each include a battery (not shown) and a battery charge / discharge circuit (not shown) for storing converted electrical energy, .

The control unit CT controls the lamp LP using power generated by the solar power generation module SM and the wind power generation module WM. In the present invention, the controller CT can adjust the illuminance of the lamp LP according to various setting conditions such as ambient illuminance, time, and power amount. For example, the controller CT senses the ambient illuminance of the illuminator and increases the intensity of the light emitted from the lamp LP as the ambient illuminance is lower. It is possible to set the lamp to irradiate light with brightness of 70% from 19:00 to 21:00 and brightness of 100% from 21:00 to 05:00 with the brightness of 50% of the set maximum illuminance. In addition, it is also possible to check the amount of power stored in the battery and adjust the illuminance of the lamp LP by calculating the amount of power to the lighting time so that the lamp LP is not turned off due to power shortage.

When the control unit CT adjusts the illuminance of the lamp LP according to the ambient illuminance, the illuminating apparatus may further include a sensor unit (not shown) for sensing the ambient illuminance. The sensor unit (not shown) includes various sensors including an illuminance sensor, and detects ambient illuminance and transmits a sensing signal corresponding to the ambient illuminance to the controller CT.

In FIG. 1, the controller CT is included in the ST. However, the controller CT may be separately implemented outside the ST.

The universal connection terminal PT not only electrically connects the lighting device with various portable devices so that the lighting device can supply power to external devices such as portable devices and additional devices but also provides communication between the lighting device and the external device . The universal connection terminal (PT) supplies power stored in the battery to an external device when an external device is connected. For example, when a portable device such as a smart phone or a smart pad is connected to an illumination device as an external device, power is supplied to the portable device. That is, an outdoor lighting device can provide a function as a temporary charging device for pedestrians who have to quickly charge the portable device.

When the communication request is received from the external device, communication with the external device is performed. In particular, the universal connection terminal PT communicates between the control unit CT and the external device so as to receive various commands from the external device to the lighting device or to transmit the status of the lighting device. Therefore, the manager of the outdoor lighting device can analyze the state of the lighting device by connecting an external device such as a notebook or smart pad to the universal connection terminal PT, and can apply a user command including the setting signal to the lighting device . For example, in order to control the illuminance of the lamp (LP), a setting signal for the illuminance according to the amount of power and the illuminance according to the ambient illuminance and the illuminance according to the time can be inputted.

Conventional outdoor lighting devices transmit state of the lighting device mainly through wired communication or are authorized by the user. However, since the wired communication network increases the installation cost as described above, the case of using the wireless communication network is gradually increasing recently. Nevertheless, there are many places where the outdoor lighting devices are arranged, and thus some lighting devices may be disposed at positions where it is difficult to perform wireless communication. In the case where the outdoor lighting device is placed in a place where both wired and wireless communication is difficult, or when the outdoor lighting device manager needs to repair the outdoor lighting device, the outdoor lighting device manager can easily operate the outdoor lighting device There is a need to enter state checking and user commands. Accordingly, the administrator of the outdoor lighting device can easily maintain the outdoor lighting device by connecting his / her portable device to the universal connection terminal (PT). At this time, the control unit (CT) may request user authentication or device authentication.

In addition, the universal connection terminal (PT) enables power to be supplied or controlled by the additional device when an additional device such as a CCTV is installed in the outdoor lighting device. Recently, as interest in safety has increased, the necessity of crime prevention is increasing, and crime prevention devices such as CCTV are increasingly installed. In the case of installing the outdoor security system separately, the cost of the installation cost is very large, so that the outdoor lighting system is often installed together with the outdoor lighting system in the place where the outdoor lighting system is disposed. When a security device is added after an outdoor lighting device is installed, an outdoor lighting device such as a power line connection and a communication network connection, (ST). However, since the outdoor lighting device of the present invention provides the universal connection terminal, it can be used immediately after simply connecting the security device to the universal connection terminal. Therefore, the installation cost of the additional device such as the crime prevention device can be minimized. At this time, the controller CT analyzes the connected external device and controls the connected external device if it is determined that the connected external device is a predetermined controllable device.

Therefore, the outdoor lighting device of the present invention is further provided with a universal connection terminal (PT), so that it can be easily connected to various external devices to supply power or perform communication. Here, the universal connection terminal PT may be a variety of terminals such as a USB (Universal Serial Bus), a SATA (Serial ATA), and an RS232 terminal. In the present invention, It is assumed that it is utilized. However, the outdoor lighting device of the present invention may have a plurality of general-purpose connection terminals PT, and the plurality of general-purpose connection terminals PT may be implemented as connection terminals of the same kind, It is possible.
