LED lights using rear and reflected light {Rembrandt Light and LED lights with reflective light}

The present invention relates to an LED lighting lamp using rear and reflected light, and more particularly, to form light from the outside of the lighting cover, and to reduce the fatigue of the user's eyes by using the light reaching the ceiling and its reflection. In addition, the present invention relates to an LED lamp using rear and reflected light having high space utilization and high light efficiency.

The present invention relates to an LED lamp using rear and reflected light. In general, the light from the light source is often unsuitable for lighting, so use a light fixture that is appropriately suited to the purpose of use, and adjust its light distribution by using its optical effects (reflection, refraction, transmission, diffusion), etc. It is also removing glare. Light fixtures or devices such as light bulbs and fluorescent lamps are installed on the ceiling or wall to supply or control light indoors or outdoors, but recently for indoor and outdoor decorative effects, aesthetics and the environment, in addition to the original purpose of illuminating the darkness. It is also used as.

In addition, as global energy and environmental issues have recently emerged, interest in light emitting diodes (LEDs), which are regarded as energy-saving clean light sources, is increasing rapidly. Also, energy saving, carbon dioxide reduction, and global environment are increasing. There is an active development of technology for general lighting LED lighting to maximize the friendly effect.

Unlike incandescent lamps, fluorescent lamps, and HID lamps, LEDs have a special structure and are light sources in which the electric energy applied to a material is directly converted into light. This phenomenon was discovered in 1907, and a blue LED was developed in 1993, attracting attention as a white LED as a light source for lighting. In recent years, performance has been improved, and white LEDs having a luminous efficiency equivalent to fluorescent lamps have emerged as light sources for illumination. The advantages of LEDs are that they consume less power, have longer lifespans than bulbs and fluorescent lamps, and are fast to respond because they are semiconductor devices. In addition, full color can be realized after commercialization of blue LEDs, and most LEDs are molded in an epoxy package, which is resistant to impact, and prevents mercury or discharge gas such as fluorescent lamps. It is environmentally friendly because it is not used.

The demand for such LED light sources is increasing rapidly. In particular, the global market of high-brightness LEDs is rapidly increasing, centering on white LEDs.
