Description
Technical field
The present invention relates to a kind of projection-type illuminating lamp for computer keyboard, belong to luminaire technical field.
Background technology
Current illuminating lamp for computer keyboard is generally built in keyboard, and there are keyboard prices, if the failures such as button damage
Appearance then needs whole the problems such as scrapping keyboard.
Invention content
Present invention solves the technical problem that being to provide a kind of being built in computer frame and not influencing computer screen brightness
Projection-type illuminating lamp for computer keyboard.
In order to solve the above technical problems, the technical solution adopted by the present invention is：
A kind of projection-type illuminating lamp for computer keyboard, it is characterised in that：Including：It is built in several line lights of computer frame
Source, the linear light source include cylinder, and one end of the cylinder is closed with concave mirror, and entering light is offered on the side wall of the cylinder
Hole, light well described in face is provided with light source in the computer frame outside the cylinder, is provided in the cylinder for will
Reflective mirror in the light reflection of the light source to the concave mirror, the other end of the cylinder are the line light light hole of opening,
The elliptical aperture being connected with the line light light hole is provided on the computer frame；The line light light hole is towards keyboard
Setting.
The light source includes LED.
The reflective mirror is set to below the light well and is arranged in 40~50 degree of angles with the cylinder inner wall, institute
The length for stating reflective mirror is less than the radius of the cylinder.
The material of the cylinder is to be protected from light material.
The material that is protected from light includes brown or black plastic.
The number of the linear light source is at least three, is uniformly distributed on the top margin of the computer frame.
Each linear light source is both provided with switch button on the computer frame, and several linear light sources are in institute
It states and is additionally provided with stacked switch button on computer frame.
A kind of projection-type illuminating lamp for computer keyboard provided by the invention, the light of LED are irradiated to reflective mirror by light well
On, reflective mirror is reflected into light on concave mirror again, and the light after concave mirror is in the line light parallel with cylinder
It is irradiated on keyboard, is used for the night illumination of keyboard, and since the line light parallel with cylinder shines directly on keyboard,
Therefore no light scatters on computer screen, does not interfere with the brightness of computer screen；It is built in several line lights of computer frame
The setting in source, the entirety for avoiding the keyboard of traditional built-in illuminating lamp are scrapped, and are greatly reduced to the keyboard of night use
It is required that.

The present invention is further described below in conjunction with the accompanying drawings.
As shown in Fig. 1~Fig. 2, a kind of projection-type illuminating lamp for computer keyboard, it is characterised in that：Including：It is built in computer side
Several linear light sources 1 of frame, the linear light source 1 include cylinder 2, and one end of the cylinder 2 is closed with concave mirror 3, the circle
Light well 4 is offered on the side wall of cylinder 2, light well 4 described in face is provided with light source in the computer frame outside the cylinder 2
5, it is provided in the cylinder 2 for by the reflective mirror 6 in the light reflection of the light source 5 to the concave mirror 3, the cylinder 2
The other end be opening line light light hole 7, be provided on the computer frame and to be connected with the line light light hole 7
Elliptical aperture；The line light light hole 7 is arranged towards keyboard.
The light source 5 includes LED.
The reflective mirror 6 is set to below the light well 4 and is arranged in 40 degree of angles with 2 inner wall of the cylinder, institute
The length for stating reflective mirror 6 is less than the radius of the cylinder 2.
The material of the cylinder 2 is to be protected from light material.
The material that is protected from light includes brown or black plastic.
The number of the linear light source 1 is at least three, is uniformly distributed on the top margin of the computer frame.
The above is only a preferred embodiment of the present invention, it should be pointed out that：For the ordinary skill people of the art
For member, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications are also answered
It is considered as protection scope of the present invention.
