Description
Technical field
The present invention relates to a kind of dustless type 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
Dustless type projection-type illuminating lamp for computer keyboard；Further, the present invention provides a kind of dust and is not easily accessible computer frame, baffle
To be light-operated, the dustless type projection-type illuminating lamp for computer keyboard of intelligent opening.
In order to solve the above technical problems, the technical solution adopted by the present invention is：
A kind of dustless type projection-type illuminating lamp for computer keyboard, it is characterised in that：Including：It is built in the several straight of computer frame
Linear light source, the linear light source include cylinder, and one end of the cylinder is closed with convex mirror, is offered on the side wall of the cylinder
Light well, light well described in face is provided with light source in the computer frame outside the cylinder, and setting is useful in the cylinder
In by the other end of the reflective mirror in the light reflection of the light source to the convex mirror, the cylinder be opening line light light extraction
Hole is provided with the elliptical aperture being connected with the line light light hole on the computer frame；The line light light hole direction
Keyboard is arranged；It is provided with baffle between the elliptical aperture and line light light hole, switch is provided on the baffle.
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.
The switch includes light-operated switch.
The baffle is close to the elliptical aperture inner wall setting, and the switch is set to the phase of the baffle and the light source 5
Opposite.
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 dustless type projection-type illuminating lamp for computer keyboard provided by the invention, the light of LED are irradiated to by light well
On reflective mirror, reflective mirror is reflected into light on convex mirror again, and the light after convex mirror is in parallel with cylinder
In linear light radiation to keyboard, it is used for the night illumination of keyboard, and since the line light parallel with cylinder shines directly into
On keyboard, therefore no light scatters on computer screen, does not interfere with the brightness of computer screen；It is built in the several of computer frame
The setting of linear light source, the entirety for avoiding the keyboard of traditional built-in illuminating lamp are scrapped, are greatly reduced to night use
The requirement of keyboard；The setting of baffle, closed elliptical aperture when for being not necessarily to open linear light source, makes dust be not easily accessible computer frame
It is interior；The setting of light-operated switch, it is light-operated to make baffle, and when needing keyboard illumination to open LED light, light is irradiated to light-operated switch
On, then baffle automatically turns on, and when closing LED light, light stopping is irradiated on light-operated switch, then baffle is automatically closed, and is realized
The intelligent opening of baffle.
