Abstract

The present invention is a lighting device using a Fresnel prism is composed of a light emitting light and a first Fresnel prism installed in the lower portion of the light to adjust the path of the light can adjust the light path in the direction desired by the user have.

Description

Lighting device using Fresnel prism {ILLUMINATING DEVICE USING FRESNEL PRISM}

The present invention relates to a lighting device, and more particularly to a lighting device using a Fresnel prism for adjusting the light path.

In general, a lighting device converts electrical energy into light energy to illuminate a space, and there are various types of incandescent lamps, fluorescent lamps, and LEDs.

However, in the conventional lighting device, since the light is irradiated in a straight line, when you want to intensively illuminate a part in a certain space, that is, to change the path of the light, an additional lighting device is installed at each position or the angle is adjusted from the beginning. You must install it. In addition, it is inconvenient to adjust the direction of the light by installing an angle adjuster to the lighting device.

An object of the present invention for solving the above problems is to provide a lighting device using a Fresnel prism to rotate the Fresnel prism to adjust the path of light.

The lighting device using the Fresnel prism of the present invention for achieving the above object is an illumination for emitting light; And a first Fresnel prism installed at a lower portion of the illumination to adjust a light path.

And a second Fresnel prism rotating below the first Fresnel prism.

The light path may be adjusted by rotating either one of the first Fresnel prism or the second Fresnel prism.

Rotating the first Fresnel prism and the second Fresnel prism is characterized in that for adjusting the light path.

Lighting device using a Fresnel prism according to the present invention has the effect that the user can adjust the path of the light to the desired position by rotating the Fresnel prism.

1 is a cross-sectional view of a lighting apparatus according to a first embodiment of the present invention.
2 is a cross-sectional view of a lighting apparatus according to a second embodiment of the present invention.

Hereinafter, a lighting apparatus using the Fresnel prism of the present invention will be described in detail with reference to the accompanying drawings.

1 is a cross-sectional view of a lighting apparatus according to a first embodiment of the present invention.

Referring to FIG. 1, the lighting apparatus according to the first embodiment of the present invention includes an illumination 100 and a first Fresnel prism 200.

The lighting 100 is an incandescent lamp, a fluorescent lamp, an LED lamp, etc., which converts electrical energy into light energy to brighten a space, and various other types of lamps may be used.

The first Fresnel prism 200 is installed under the light 100 to refract the light 400 emitted from the light 100 to change the path of the light 400, that is, the angle of the light 400. . Here, when the first Fresnel prism 200 is rotated, the path of the light 400 can be adjusted.

This allows a user to select and illuminate a space required by a user with a single lighting device without having to have multiple lights in a large space.

2 is a cross-sectional view of a lighting apparatus according to a second embodiment of the present invention.

2, the lighting apparatus according to the second embodiment of the present invention further includes a second Fresnel prism 300 under the first Fresnel prism 200 of FIG. 1.

Here, when the first Fresnel prism 200 and the second Fresnel prism 300 is installed symmetrically, the light 400 is refracted by the first Fresnel prism 200 and the second Fresnel prism 300 As the angle of the light 400 is increased by one more refraction, the light path may be adjusted in a wider range when only one first Fresnel prism is used.

In addition, when one of the first Fresnel prism 200 or the second Fresnel prism 300 is rotated to control the path of the light 400 in a predetermined direction, the first Fresnel prism 200 and the first Rotating both of the two prism prisms 300 can control the path of the light 400 in various directions than when rotating one.

While the present invention has been particularly shown and described with reference to exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, Of course, this is possible. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be defined by the equivalents as well as the claims that follow.

100: lighting 200: first Fresnel prism
300: second Fresnel prism 400: light
