A lighting apparatus includes a LED module provided at the central side of a chassis and a reflection sheet reflecting light emitted from the LED module. The LED module emits light to the outer edge portion of the chassis and then the light is reflected on the reflection sheet to perform illumination so that glare can be reduced. Then, the light emitted from the LED module is reflected on the reflection sheet in many directions so that a substantially uniform illuminated light with less illumination unevenness can be achieved. The LED module is not arranged at the outer edge portion of the chassis so that moment acting on the chassis can be reduced. Therefore, the deformation of chassis can be prevented.

A lighting device may include a housing interior, a light exit, a light source, and a light converter. Output light is outputted from the light exit by emitting primary light from the light source. In response, the light converter emits secondary light of one or more wavelengths different than the primary wavelength, and the output light includes a combination of the primary light and the secondary light. The color of the output light may be tuned by adjusting a color parameter of the output light. The adjustment includes adding a color tuning material at a location in the housing interior where primary light is incident on the color tuning material. The color tuning material is configured for emitting auxiliary light in response to the incident primary light. Subsequently, the lighting device produces color-tuned output light that includes a combination of the primary light, the secondary light and the auxiliary light.

An energy-saving LED-based device with improved support structure for high-brightness LED chips for room illumination. The improved support structure positions the LED chips in such a way that the light is emitted towards the ceiling, the floor, or any other surface, along such a path that human eyes are unlikely to cross the light path. Because the bright light is kept away from people's eyes, there is no need for shades, which absorbs some of the light produced. Two of the most common shades are the light breakers surrounding the standing lamps in residential spaces and the light breakers around the lights near the ceiling that are part of the indirect lighting. Dispensing with the shades increases the overall energy efficiency because the light energy absorption by the shade is obviated. The illumination created by such improved LED arrangement is also more pleasing to humans because it creates less shadows. 1.
