Abstract: A luminous safety ball including an inner glowing body and a foam sphere covering the inner glowing body is provided. The inner glowing body is not a perfect sphere, the foam sphere has a non-uniform thickness, and light emitted by the inner glowing body passes through the foam sphere and permeates through a surface of the foam sphere to form light with different brightness thereon.

Abstract: A luminous ball with remote activation capability includes a sphere, a cover and a light-emitting device. The cover wraps an external circumferential surface of the sphere and is made of a light-transmissive material. At least one seam is formed on the cover, and a plurality of seam apertures are disposed in pairs along two sides of the at least one seam. The light-emitting device is disposed in the sphere and includes a light-emitting unit, a power unit, a wireless transmitter-receiver unit and a main control unit. The main control unit is operably configured to provide an electrical connection between the light-emitting unit and the power unit after obtaining an activation signal received by the wireless transmitter-receiver unit such that light emitted by the light-emitting unit penetrates the sphere and the cover and is visible through the at least one seam and the plurality of seam apertures.

Abstract: A luminous ball is provided, including a sphere, at least one covering spliced to wrap the sphere, at least one seam formed on an edge of the covering, a plurality of thread apertures disposed at two sides of the seam, at least one thread penetrating the plurality of thread apertures to stitch the edge of the covering between the two sides of the seam, and a light-emitting device disposed in the sphere. The light-emitting device includes a light-emitting unit, a power unit, and an electrical insulating unit breaking an electrical connection between the light-emitting unit and the power unit. The electrical insulating unit is removable. The electrical connection between the light-emitting unit and the power unit is provided when the electrical insulating unit is removed such that lights emitted by the light-emitting unit penetrate the sphere and are visible through the seam and the thread apertures.
