Title:
SHOWCASE LIGHTING DEVICE HAVING HORIZONTAL LIGHT DISTRIBUTION
Document Type and Number:
WIPO Patent Application WO/2018/043806
Kind Code:
A1
Abstract:
The present invention provides a showcase lighting device wherein horizontal light distribution is deployed in the inner space of a showcase through light source refraction by a plastic optical fiber (POF) and a prism, thereby improving the overall lighting brightness inside the showcase, and the showcase lighting device is installed in a showcase having a plurality of shelves in a display space for displaying products therein and an opening/closing door such that heat-insulating performance is efficiently implemented, thereby lighting the inner display space of the showcase. Particularly, the present invention provides a showcase lighting device having horizontal light distribution, comprising: diffusing non-specular portions formed in both sides of the inner display space of the showcase so as to form rough surfaces that scatter light and generate diffused light, respectively; prism pattern portions positioned on both side ends of the opening/closing door of the showcase and installed on left and right sides so as to correspond to shelf label areas of the display space, respectively, thereby refracting/reflecting light perpendicularly toward the shelf label areas; and lighting portions installed on the showcase so as to correspond to the prism pattern portions so as to emit and transmit light toward the prism pattern portions, respectively, wherein LED lighting is installed on the lighting portions in order to generate light, and the showcase lighting device comprises a POF connection unit for transmitting light from the LED lighting in the longitudinal direction toward the prism pattern portions such that light propagates while repeating total reflection.
