Description

Lighting apparatus

The present invention relates to a lighting apparatus, and to a lighting apparatus including a plurality of light emitting diode modules electrically connected to each other.

Fluorescent lamps are widely used as light sources for lighting devices today.

The fluorescent lamp includes a vacuum glass tube coated with a fluorescent material on an inner wall, a mercury gas filled inside the vacuum glass tube, and electrodes disposed at both ends of the vacuum glass tube. Here, when a high voltage is applied to the electrode, a discharge occurs inside the vacuum glass tube, and the mercury gas emits ultraviolet rays by the discharge. In this case, the emitted ultraviolet rays are converted into visible light by the fluorescent material and emitted to the outside.

When such a fluorescent lamp is applied to the subway, there was a case where the fluorescent lamp is temporarily unlit in a section in which the power supply is changed. In addition, when the fluorescent lamp is re-lit, it may increase eye fatigue due to the flicker of the fluorescent lamp. In addition, the fluorescent lamp has only 25% of the energy efficiency of converting to visible light in terms of structure, and the lamp has a short lifespan, which has to be replaced frequently from 6 to 13 months of continuous operation.

In particular, fluorescent lamps use mercury, which is harmful to the human body, and thus are subject to environmental regulations. Therefore, it is urgent to develop new light sources for lighting devices.

Therefore, as a fluorescent lamp mainly used as a conventional lighting device has problems such as environmental problems and driving instability, a new light source that can replace this has to be developed.

An object of the present invention is to provide a lighting device that is eco-friendly and does not flicker upon lighting, including a plurality of light emitting diode modules electrically connected to each other.

In order to achieve the above technical problem, an aspect of the present invention provides a lighting device. The lighting device includes a case having a receiving portion; A plurality of light emitting diode modules disposed in the receiving portion; An electrical connection member electrically connecting the plurality of light emitting diode modules to each other; And a driving unit disposed on a rear surface of the case and configured to apply a driving voltage to the light emitting diode module.

The light emitting diode module may include a printed circuit board; A plurality of light emitting diode chips mounted on the printed circuit board; And a connector housing mounted at both ends of the printed circuit board and fastened to the electrical connection member.

In addition, the electrical connection member includes a wire and a connector respectively disposed at both ends of the wire and electrically connected to the printed circuit board.

In addition, the connector is provided with a locking member for fixing to the printed circuit board.

In addition, the light emitting diode module may further include a diffusion member covering the case.

In addition, the case may further comprise a fixing member for fixing the light emitting diode module.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings of the lighting apparatus. The following embodiments are provided as examples to sufficiently convey the spirit of the present invention to those skilled in the art. Accordingly, the invention is not limited to the embodiments described below and may be embodied in other forms. In the drawings, the size and thickness of the device may be exaggerated for convenience. Like numbers refer to like elements throughout.

The light emitting diode chip 111 may include a light emitting diode device which is a semiconductor device that emits light when a current is applied. That is, the light emitting diode chip emits light at the same time as power is input, and thus is more stable than the fluorescent lamp. As a result, the LED chip can eliminate visual discomfort compared to the fluorescent lamp.

The light emitting diode chip 111 implements white light. For example, the light emitting diode chip may include a light emitting diode emitting light with blue light and a phosphor disposed around the light emitting diode to convert a part of the blue light into yellow light. In this case, the light emitting diode chip may implement white light due to the color mixture of the blue light and the yellow light. Alternatively, the light emitting diode chip may include a light emitting diode device emitting red, green, and blue light, respectively, and the light supplied from the light emitting diode device may be mixed with each other to implement white light.

Accordingly, since the light emitting diode chip 111 does not require a mercury gas, which is harmful to a human body like a conventional fluorescent lamp, it may be environmentally friendly compared to a conventional fluorescent lamp and thus may be free from environmental regulations.

The connector housing 113 serves to electrically connect the plurality of light emitting diode modules 110 together with the electrical connection member 117 to be described later. The connector housing 113 is mounted at both ends of the printed circuit board 112.

The distance D between the connector housing 113 and the edge of the printed circuit board 112 may be 15 mm to 20 mm. This is because the length of the electrical connection member 117 to be described later is formed in the range of 20mm to 40mm. Here, the distance between the edge of the connector housing 113 and the printed circuit board 112 may be changed according to the length of the electrical connection member 117.

The case 100 has a driving unit 120 for applying a driving voltage to the printed circuit board 112. The driver 120 may be electrically connected to at least one of the plurality of light emitting diode modules 110. For example, the driving unit 120 is electrically connected to the first and second connector housings 130a and 130b provided in the light emitting diode module 110 disposed in the center of the plurality of light emitting diode modules 110. Can be.

The plurality of light emitting diode modules may be electrically connected to each other by an electrical connection member, and the driving unit may apply a driving voltage to all of the plurality of light emitting diode modules. In this case, when any one of the plurality of light emitting diode modules causes a failure to be turned on, only the defective light emitting diode module or the light emitting diode chip may be easily replaced, thereby reducing the maintenance cost of the lighting apparatus.

In the embodiment of the present invention, although shown and described as the first and second connectors 130a and 130b for direct electrical connection with the drive unit 120, the connector housing for direct electrical connection with the drive unit 120 It does not limit the number of 113. For example, one or more connector housings 113 for electrical connection with the driving unit 120 may be provided. In addition, although the first and second connector housings 130a and 130b are illustrated and described as being disposed at the center portion of the case 100, the first and second connector housings 130a and 130b may be used to define the positions of the first and second connector housings 130a and 130b. It is not. For example, the first and second connector housings 130a and 130b may be disposed at an edge of the case 100.

In addition, the light emitting diode module 110 may further include a diffusion member 130 covering the case. The diffusion member 130 diffuses the light provided from the light emitting diode module 110, the illumination device can uniformly emit light.

In addition, the light emitting diode module 110 may be fixed and assembled to the case using a fixing member (not shown). Examples of the fixing member may be a screw or an adhesive member.

Therefore, in the exemplary embodiment of the present invention, the lighting apparatus may include a plurality of light emitting diode modules, and thus may be free from environmental regulations by providing an environment-friendly light source as compared to a conventional fluorescent lamp. In addition, since the light emitting diode module is driven at the same time as the current is applied, it is possible to solve the visual inconvenience such as flicker that occurs in the conventional fluorescent lamp.
