Description

LED lighting fixtures capable of multi-color indirect lighting}

The present invention relates to a frame that forms the side of a lighting fixture by double-injecting synthetic resin of an opaque material and a transparent material and cutting and bending a frame extending in the longitudinal direction to a required length, and more particularly, LED lighting inside the opaque part. It relates to an LED lighting fixture capable of indirect multicolored lighting that can produce more diverse lighting by combining color plates of various colors that can transmit light.

As a commonly used indoor lighting, a so-called ceiling lamp in which a box-shaped case is coupled to or embedded in a ceiling and installed, and a light source such as a fluorescent lamp is installed in the case is widely used. Ceiling lamps are provided in the form of an open interior side of the case, but there are also examples in which a light diffusion plate or a protective plate for protecting a light source is installed for soft indoor lighting.

Recently, lighting using LEDs (Light Emitting Diodes) has been attracting attention. LED lighting devices use a plurality of LEDs as a light source, and compared to light sources such as incandescent lamps and halogens, they are smaller, have longer lifespan, and have higher efficiency and faster response. There is an advantage.

Among these LED lights, the light that requires directionality uses a lens unit and a reflective member to give the light emitted from the LED element a certain directionality so that it is irradiated to a desired irradiation area, and the LED light that does not require directionality is diffused by scattering light. It is common to use a plate, and a representative example is a flat-type LED light, and such an LED light requires a frame for supporting the diffuser plate.

In Patent Registration No. 10-1069726, in order to solve the problem that the fixing bolt is exposed to the outer surface of the frame and spoils the appearance, a support having an accommodation groove for accommodating the head of the fixing bolt is coupled to the support and covers the accommodation groove. By introducing a concealing member that conceals the fixing bolts, a neat ceiling-type lighting fixture body frame was proposed without compromising the appearance of the lighting fixture.

However, these conventional lighting fixtures have problems that are not economical due to increased manufacturing and assembly costs because a separate mold must be manufactured or a frame and a corner member must be separately manufactured and assembled to configure the body.

In addition, since the lighting of the light source is diffused only downward through the diffusion plate, there is a limitation in directing various lighting suitable for space and atmosphere.

Accordingly, the applicant of the present application cuts and bends the frame extended in the longitudinal direction in Patent Application No. 10-2019-0117695 to a required length, and a lighting fixture composed of a bendable frame capable of firmly connecting the junction by a connecting member. suggested.

The applicant of the present application intends to propose an LED lighting fixture capable of directing lighting of various colors by further improving the configuration of such a frame.
