The cover may include a hollow and at least partially elastic body in a pre-formed shape having an inner surface and an outer surface, wherein the body is removable and frictionally secured to said bulb to form an envelope around the bulb. The body may also include a collar and a bulbous section, which extends from the collar. The collar is configured to engage the base of the light bulb and create a substantially airtight seal between the base and the body. The body is fabricated from a light pervious material, and any light transmitted by the cover is preferably substantially diffuse.Type: GrantFiled: February 1, 2012Date of Patent: December 23, 2014Assignee: St. Albert Innovations, LLCInventor: Ryan Claudet

Patent number: 8878423Abstract: Disclosed is a light-emitting device, including an LED light source and a light diffusion element. The light diffusion element, covering at least a part of the LED light source, is composed of a first polymer, a second polymer, or a blend of them. The first polymer has a larger crystal diameter than that of the second polymer. The first polymer is made of polypropylene or ethylene-propylene copolymer. The second polymer is made of polyethylene, polypropylene, or ethylene-propylene copolymer. A blend of certain ratios of the first and second polymer gives rise of an excellent material that has improved light diffusion. This material can be widely adopted to current light fixtures for its evenly distributed lighting and great brightness.Type: GrantFiled: December 30, 2010Date of Patent: November 4, 2014Assignee: Industrial Technology Research InstituteInventors: Pei-Ying Chang, Shi-Ing Huang, Tien-Fu Huang, Chen-Dao Shiao
