Abstract
The invention relates to a light source for even light distribution. Light rays emitted by LED lamp wicks are too concentrated, so that the distribution in space is uneven; a plurality of dispersed LED lamp wicks are assembled in a bulb shell; and the difficulty of even distribution of all dry LED lamp wicks in the space position is higher, so that the even distribution is difficultly realized. Electric transverse parts are connected with electric longitudinal parts to form substrates; LED units and electrodes thereof are connected to the substrates, and form loops with the substrates; and a certain number of the substrates of the electric longitudinal parts are randomly selected, and are wound to conveniently form the light source with evenly distributed lamp wicks in the space position. Insulation fractures are arranged among the electric transverse parts for cutting off one electric connection of the adjacent electric longitudinal parts, and the distribution and position relations of the insulation fractures are allocated to obtain different electric connection relations among the electric longitudinal parts so as to realize various electric loops, so that various specification requirements can be satisfied, and the production is convenient.
