Furthermore, at least one side wall of the side walls around the bottom cover is provided with a plurality of light holes.

Further, the light guide plate is in a frame shape and is matched with the bottom cover, a plurality of fixing holes are formed in the light guide plate, and fixing columns matched with the fixing holes are arranged on the bottom cover. The light guide plate is frame-shaped, is convenient for produce and process, and is provided with the fixed orifices on the light guide plate, can fix the light guide plate on the bottom cover through fixed column and fixed orifices, makes the light guide plate laminate more on the lateral wall of bottom.

Further, a light condensing structure is arranged on the inner side face of the light guide plate, and the light condensing structure is a groove and a raised line which are arranged intermittently.

Furthermore, the light guide plate is made of plastic material doped with fluorescent powder. The light guide plate is added with fluorescent powder during injection molding to play a role in guiding light, and the production process of the light guide plate is the prior art and is not explained in detail in the specification.

Furthermore, the light holes are oval and are distributed in a vertically staggered manner. The light holes are arranged in a vertically staggered manner, so that light is projected like a projector to form light, and the light is projected onto a desktop to form a staggered light spot form, so that the attractiveness is increased; if each side is provided with the LED lamp of two kinds of colours at least, then corresponding colored light can be passed through to this side, increases and dazzles various effect.

Further, be provided with the illuminating part on the key cap, the illuminating part is transparent or fretwork, and the bottom of key cap also is provided with the key position LED lamp corresponding with the key cap. The luminous of key cap belongs to prior art, adds the side of keyboard and gives out light on the luminous basis of key cap, has strengthened the various effect of dazzling of whole device, has more the individuality.

The advantage of this application lies in, the side of this keyboard sets up a plurality of light trap, and when the inside LED of keyboard lighted, jets out light through the light trap through the light guide plate, increases the aesthetic property, satisfies the individualized demand of user.
