Abstract

The invention discloses a projection type computer keyboard lighting lamp. The projection type computer keyboard lighting lamp is characterized by comprising multiple linear light sources (1) arranged in a computer frame. The linear light sources (1) comprise cylinders (2). A convex mirror (3) is sealed at one end of each cylinder (2). Light inlets (4) are formed in the side walls of the cylinders (2). Light sources (5) right opposite to the light inlets (4) are arranged at the portions, outside the cylinders (2), in the computer frame. Reflective mirrors (6) for reflecting light of the light sources (5) to the convex mirrors (3) are arranged in the cylinders (2). The other ends of the cylinders (2) are provided with open linear light outlets (7). Oval holes communicated with the linear light outlets (7) are formed in the computer frame. The linear light outlets (7) are formed towards a keyboard. The projection type computer keyboard lighting lamp is arranged in the computer frame and cannot affect the brightness of a computer screen.

Description

technical field [0001] The invention relates to a projected computer keyboard lighting lamp, which belongs to the technical field of lighting appliances. Background technique [0002] Current computer keyboard lighting lamps are generally built in the keyboard, and there are problems such as expensive keyboards, and if failures such as key damage occur, the keyboard needs to be discarded as a whole. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a projection type computer keyboard illuminating lamp which is built into the frame of the computer and does not affect the brightness of the computer screen. [0004] In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is: [0005] A projected computer keyboard lighting lamp, characterized in that it includes: several linear light sources built into the frame of the computer, the linear light sourc...
