LED lamp including positioning frame for general illumination

#1. Field of the Invention

#This invention relates to a high-efficiency LED lamp, particularly to one employed for indoor illumination, which is able to concentrate light and increase lighting efficacy.

#2. Description of the Prior Art

#This invention will be better understood by referring to the accompanying drawings, wherein:

#FIG. 1 is a perspective view of a high efficiency LED lamp of the present invention;

#FIG. 2 is an exploded perspective view of a high efficiency LED lamp of the present invention;

#A preferred embodiment of a high efficiency LED lamp of the present invention, as shown in FIGS. 1, 2, 3A and 3B, includes a positioning frame base 1, two LED bars 2, a light guide plate 3, a reflection sheet 4, an optical film 5, a power supply unit 6, a protective cover 7 and an integration frame 8 combined together.

#The positioning frame base 1 consists of a fixing frame 10 and a base plate 11. The fixing frame 10 is rectangular, made of galvanized iron, spongy iron aluminum-magnesium alloy, Teflon, carbon, or plastic material like acrylics, polyvinyl chloride (PVC) or polypropylene (P.P.), and shaped by sheeting, casting or by plastic injection molding and formed with a thickness between 0.2 mm and 1 mm. The fixing frame 10 has its peripheral edge extending inwardly perpendicularly, forming two opposite first sheets 100 and two opposite second sheets 101, providing the fixing frame 10 a cavity. The two opposite first sheets 100 respectively have their side edges bored with a plurality of locking holes 1000 and convection holes 1001 and their inner sides formed with a plurality of recessed clasp points (not shown). The two opposite second sheets 101 respectively have one edge extending outward perpendicularly to form a combining member 1010 bored with a locking hole 10100.

#The base plate 11 positioned on the inner side of the fixing frame 10 is rectangular, made of galvanized iron, spongy iron, aluminum-magnesium alloy, Teflon, stainless steel or carbon, and shaped by pressing and bending and formed with a thickness between 0.2 mm and 10 mm. The base plate 11 has its peripheral edge perpendicularly extended and bent toward one side to form a narrow sheet 110, in which these side surfaces form an accommodating space 111, and side edges having a plurality of projecting points 1101 for corresponding engagement with the recessed clasp points on the inner side of the fixing frame 10 for securing the base plate 11 together with the fixing frame 10.
