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.
