Description

Functional lighting using a light guide plate {LIGHT WITH LIGHT GUIDE PLATE} The present invention relates to a functional lighting fixture using a light guide plate that is fixedly installed on the ceiling of a home or office, and more specifically, it is a functional lighting fixture using a light guide plate that deviates from the structure of conventional ceiling lighting fixtures by being formed separately into a ceiling fixing plate body and a lighting frame body, and configured such that a flat light source body using a light guide plate is installed and fixed in the lighting frame body, thereby allowing the lighting frame body having a light source to be fastened and installed to the fixing plate body installed in close contact with the ceiling, thereby faithfully achieving the original purpose of the lighting fixture while simultaneously creating a more luxurious and simple exterior by being installed in close contact with the ceiling surface. Generally, lighting fixtures are essential for brightly illuminating the interior of homes, such as detached houses or apartment buildings, and must also be provided to ensure excellent indoor illumination within buildings such as offices, officetels, schools, and government offices. Lighting fixtures are mostly installed either fixedly or recessedly in the lower part of the indoor ceiling. Depending on the installation method, they are classified into ceiling-mounted lights and ceiling-hanging lights; depending on the installation form, they are classified as ceiling lights or ceiling-recessed lights; and depending on the type of lamp embedded in them, they are classified into fluorescent lights, incandescent lights, and LED lights. Ceiling lights are most commonly constructed by installing a lamp, socket, and ballast inside a fixed body formed by bending a metal plate into a circular or square shape, and attaching a lighting cover made of milky white synthetic resin or glass to the bottom of the fixed body. When power is applied to the lamp coupled inside the fixed body and it lights up, the light from the lamp is transmitted and diffused through the lower lighting cover, performing the function of evenly illuminating the entire room. Ceiling lights consist of a combination of a fixed body and a lighting cover, which are the most basic structures. Since this basic structure provides the most efficient manufacturing and productivity while generating economic benefits through mass production, most ceiling lights have the same structure, form, and function. Conventional ceiling lights necessarily use a bracket to fix the main body to the ceiling finishing material or ceiling slab. Since the bracket, which is made by bending a metal plate and is a rectangular shape smaller than the main body, is directly fixed to the underside of the ceiling finishing material or slab and the main body is then fixed using said bracket, conventional ceiling lights have a certain distance or gap from the ceiling surface. Conventional ceiling lights have a problem in that, when applying various light sources such as fluorescent lights or LEDs, they cannot break away from the thickness or height of lights used since the past due to the inherent thickness of fluorescent lights or the converters that are essential when using LEDs, and thus must always maintain an installation state where they protrude from the ceiling surface toward the interior. Ceiling lights in the form of flat light sources utilizing side light sources and light guide plates are being used as a measure to reduce the thickness or height of ceiling lights while simultaneously achieving more even lighting. In lighting fixtures using flat plate light sources, a light guide plate is placed for a side light source, such as a fluorescent lamp or an LED light source, and a reflective sheet and a diffuser sheet are placed above and below the light guide plate, respectively, so that the light from the side light source is illuminated in a flat plate shape through the light guide plate. The reflective sheet blocks the light from the light guide plate from being lost in unnecessary directions, and the light from the diffuser sheet is diffused more evenly to prevent glare or localized concentrated light emission. Ceiling lights using flat panel light sources can be installed flush against the lower surface of the ceiling, allowing for a more minimalist and luxurious interior design. Conventional ceiling lights with flat panel light sources have the problem that the frame itself, which is used to combine and fix light source modules such as side light sources and light guide plates, is directly fixed to the ceiling, so the frame fixing members are exposed to the outside and protrude, resulting in an unattractive appearance and a failure to create a luxurious and simple exterior due to the exposure of the frame fixing members.
