Abstract: An LED light emitting apparatus according to an embodiment of the present invention includes a plurality of LEDs, a case having the LEDs at its front side, and a plurality of bolts each having a threaded portion for fixing the case to outside. The case has a plurality of insertion portions each allows inserting a bolt from the front side through the back side of the case. Each of the insertion portions has at its inner portion an elastic member having a first inner diameter which is smaller than the outer diameter of the threaded portion, and the elastic member is fixed in the insertion portion.

Abstract: The present invention provides the lighting apparatus cable that allows it to easily attach the lighting module and enables it to improve the productivity. A flat cable used in a lighting apparatus having a plurality of lighting modules disposed in series, for connecting the lighting modules in such a manner that colors and/or luminous intensities of emitted lights of the lighting modules can be controlled, the flat cable comprising: at least four conductors disposed in parallel which include two signal conductors disposed at both sides of the cable and two power feeding conductors; a sheath member covering the at least four conductors to integrate; and notches formed on both sides of the cable so as to cut the signal conductors.

Abstract: A highly reliable LED display apparatus is provided in which dust and other similar particles are prevented from entering spaces formed between light-emitting diodes and openings in a mask member provided on a circuit board. The LED display apparatus has the circuit board, the light-emitting diodes provided at predetermined positions thereon, and the mask member which is disposed approximately parallel to the circuit board. The mask member has openings at positions corresponding to the light-emitting diodes which are placed inside the respective openings. In the LED display apparatus described above, the openings of the mask member have fine projections on side surfaces thereof. The fine projections can be formed on the mask member by a flock processing technique.
