PNG media_image4.png 360 456 media_image4.png Greyscale Blalock et al. teaches an optical device (interpreted as protective cover 210) that is detachably coupled to the lens (see at least Fig. 2, LED holder 105) of the lighting device by at least the flange of one or more apertures being snap fit over the head of the screw without removing the fastener from the sleeve (see at least column 7, lines 49-67 “the protective cover 210 can be configured and shaped to aid in the centering of additional (primary or secondary) optical elements. This can be achieved by adding additional flanges that extend upward in a straight, angular, or curvilinear manner from the board cover 305 in a manner that is complementary to the shape of the additional optical element or elements. By designing the protective cover with a complementing geometry to that of an upper optic, it will assist in ensuring the proper placement of that optic with respect to the LED package, thereby providing for the desired light output from the luminaire 100. In other example embodiments of the invention, the protective cover 210 covers the LEDs for protection during shipping/installation and is removable by various means such as Snap-fit connection to the base plate 205, screw-thread connection to the base plate 205, or other removable connection means. Additionally, in Some example embodiments of the invention, the protective cover 210 prohibits handlers or installers of the LED Holder from damaging the LED package”). It would have been obvious to one having ordinary skill in the art before the time of the effective filing date of the invention to modify the optical device of Yuan et al. to explicitly teach a flange of one or more apertures being snap fit over the head of the screw without removing the fastener from the sleeve as taught by Blalock et al. as an alternative way of securing the optical device to the lighting system (see column 7, lines 49-67 of Blalock et al.).
