Description

LED lighting with rotation and tilt

The present invention relates to LED lighting capable of rotation and tilting, and more particularly, to an LED lighting apparatus capable of rotation and tilting, which is easy to supply power even when the LED lighting unit rotates.

In general, LEDs have a longer life and lower power consumption than conventional lights, and recently, products that can replace existing lights such as street lamps and indoor lights have been developed.

In particular, the LED lighting device that can control the light distribution from the LED lighting device having a fixed light distribution has been developed by the 'Light Pollution Prevention by Artificial Lighting Act', which has been implemented since February 1, 2013. The main contents of the Act on the Prevention of Light Pollution by Artificial Lighting are to protect people's health from misuse of artificial lighting and to prevent ecosystems, and to set the light emission allowance standards for building lighting, signboards, and various infrastructure lighting. It is to manage the light.

This means that street lights and other lights on the road must comply with the light emission limits in order to prevent intruded light from entering urban buildings, buildings, billboards, etc. into the surrounding buildings at night. Directional light distribution needs to be adjusted.

As the legal basis for adjusting the light distribution of the LED lighting device is prepared, recent LED lighting devices have been proposed to control light distribution.

Structures for adjusting the light distribution of the conventional LED lighting apparatus, relates to a structure for widening the light distribution of the lighting module, such as Patent Publication 10-2011-0108269, or to adjust the light distribution using a lens, such as Patent No. 10-0961676 There are proposed inventions for how to do this.

However, the structure of widening the light distribution of the lighting module has a problem of increasing the light pollution by increasing the penetration light according to the increase of the light distribution area, and the technology of controlling the light distribution using the lens can reduce the light efficiency by using the lens. In addition, it is possible to anticipate the inconvenience of having to replace a suitable lens as necessary and a problem of making a suitable lens for each lighting.

In the LED lighting apparatus including a plurality of lighting module units to adjust the light distribution, an example of adjusting the angle of each lighting module unit is disclosed in Korean Patent Publication No. 10-2012-0093712 (LED lighting apparatus for adjusting the irradiation angle, published date 2012 August 23).

This is related to the configuration of coupling to the heat sink in a state where the installation angles of a plurality of lights are adjusted, but there is no detailed description of how to power the LEDs in the lights, once installed once again to adjust the angle There was a problem that must be combined after adjusting the angle.

In addition, when power is supplied to the LED of the lighting unit using the wire, there is a possibility that problems such as the flow angle or the degree of rotation may be limited by the wire or the wire may be disconnected due to excessive rotation.

The technical problem to be solved by the present invention in view of the above problems is to provide a LED lighting apparatus capable of rotating a plurality of lighting modules, the rotation and tilting can adjust the tilt angle.

In addition, another technical problem to be solved by the present invention, it is possible to supply the power stably even when rotating each of the lighting module, the rotation and tilting to prevent the degree of rotation is limited by the disconnection or interference of the wires It is to provide a possible LED lighting device.

In addition, another technical problem to be solved by the present invention is to provide an LED lighting device capable of rotating and tilting that can easily replace the lighting module, if an error occurs in each of the lighting module.

LED rotatable and tiltable LED lighting apparatus for solving the above problems, the body portion, the rotating portion coupled to the body portion and rotatable in a direction parallel to the coupling surface of the body portion, the body portion and the rotating portion While connecting the power between, including a power connection for supplying power by contact between the electrodes regardless of the degree of rotation of the rotating portion.

LED lighting device capable of rotating and tilting the present invention, by using a power connection that can stably supply power even in the rotating state of the lighting module, without using a wire when coupling each of the plurality of lighting modules to the body, Rotating and tilting the lighting module freely, there is an effect that the light distribution can be easily adjusted.

In addition, when the lighting module rotates according to the use of the power connection, there is an effect that the wire is disconnected or the rotation angle is limited by the wire.

In addition, since the present invention does not use a wire, each of the plurality of lighting modules can be separated and replaced, thereby reducing the time required for maintenance and repair, and reducing the cost.

In this case, since the position thereof does not vary, the coupling part 50 is in contact with each other in a state in which the rotating part 40 is coupled to the flange 30, and one or more spring electrodes 22 are provided at the center. Since it is spaced apart from the electrode 21 by a certain distance, the ring-shaped electrode 62 is also a ring-shaped structure spaced apart by the distance between the spring electrode 22 and the center electrode 21 with respect to the electrode pin 61. The spring electrode 22 can be in contact with the rotating part 40 regardless of the rotation state.

Therefore, even if the rotating part 40 is free to rotate, the power supplied to the first substrate 20 can be easily transferred to the second substrate 60.

Power supplied to the electrode pin 61 and the ring-shaped electrode 62 of the second substrate 60 is supplied to the optical module unit 80 through the wire 63.

Tilting is possible in the vertical direction.

The shape of the second tilt arm 71 of the tilt part 70 is also an empty space except for the second tilting center part 73 in which the fastening hole 42 is provided, and in the first tilt arm 41. An extended wire 63 may extend to the second tilt arm 71.

A lower portion of the second tilt arm 71 is provided with a mounting portion 74 to which the optical module unit 80 is coupled, and a second wire passing through the mounting portion 74 from the second tilt arm 71.
