发明名称 FLAT AND THIN LED-BASED LUMINARY
摘要 <p>A light-emitting device (100), comprising a plurality of light emitting diodes (107) arranged spaced apart from each other on a substrate (108), is provided. The device further comprises a light guide plate (101) having a front surface (102) and an opposing back surface (103) that is provided with an array of protrusions (104) extending towards said substrate. The light guide plate is arranged such that light emitting diodes are located in spaces formed between adjacent protrusions. The light from the plurality of LEDs will be transmitted in to the light guide plate and will be distributed therein before exiting the light guide plate via the front side thereof. Thus, the present invention provides a light-emitting device that provides well- distributed light from a plurality of point light sources.</p>
