Title:
LIGHT BULB HAVING WIDE ANGLE LIGHT DISPERSION AND METHOD OF MAKING SAME
Document Type and Number:
WIPO Patent Application WO2005109534
Kind Code:
A3
Abstract:
The present light bulb includes a wide angle dispersed light which uses, as a source of light dispersion, crystalline particulate material incorporated into the molded or formed material of the light bulb. The crystalline particulate material can be incorporated into the light bulb material prior to the molding or forming process or it can be later applied to the surfaces of the light bulb. The crystalline particulate material are chosen to provide high reflectivity and dispersion qualities for the parts of the light bulb and are further chosen and incorporated according to the function of the particular piece or part therein incorporated. A light tuning element may also be used to further enhance the light dispersion qualities of the light bulb. Methods for making the present light bulb are also provided.
