Abstract: An information display board with improved display performance by light-extending light sources is revealed. The information display board includes a display board and a plurality of light-extending light sources each of which consists of a light emitting diode (LED) and a reflective panel. The LED has a light emitting side and a backside while the reflective panel is disposed on the light emitting side of the LED for reflecting a part of light emitted from the light emitting side to the display board on the backside to form an expanded area. Thus illuminance and illuminated area of information shown on the display board are increased. By continuous lighting generated, messages/information shown on the information display board such as traffic sign can be read more clearly and comfortably.

Abstract: A light-emitting diode lighting structure for improving back-illumination efficiency is revealed. The light-emitting diode lighting structure is disposed on a substrate and composed of a light emitting diode (LED) and a reflective panel. The LED provided with a packaging lens has a light emitting side and a backside. The reflective panel is arranged at the light emitting side of the LED and located adjacent to the packaging lens. A part of light emitted from the light emitting side is reflected to the substrate by the reflective panel. Thereby the illumination on the substrate at the backside can be increased. Moreover, continuous lighting is generated so that messages shown on signboards can be read more clearly and comfortably when a plurality of LEDs is disposed on and applied to the signboards.
