Description

BACK LIGHTING TYPE LED LIGHTING DEVICE

The present invention relates to a backlight type LED lighting device, and more specifically, by providing an LED substrate for backlighting in a backlighting LED mounting groove formed in a subframe for back lighting above a base plate, It relates to a backlight type LED lighting fixture capable of implementing backlighting of a ceiling by emitting light from an LED element of an LED substrate for backlighting.

In general, as an indoor lighting lamp, a so-called ceiling lamp in which a case formed in a box shape is coupled to or embedded in a ceiling, and a light source such as a fluorescent lamp is installed in the case is widely used.

Although the ceiling lamp is provided in an open form on the indoor side of the case, there are also cases in which a light diffusion plate or a protective plate for protecting the light source is installed for soft indoor lighting.

In recent years, lighting using LED (Light Emitting Diode) has been attracting attention, and LED lighting devices use a plurality of LEDs as light sources. There is an advantage. The LED lighting lamp includes a diffusion plate for scattering light, and the diffusion plate is configured to be assembled at a lower portion of the frame.

However, conventional LED lighting lamps do not have a backlighting (light distribution) function because the LED lighting is irradiated only downward, and the overall structure is monotonous, so there is a problem in that it cannot meet the needs of consumers who need various functions and structural rigidity.
