Abstract
The utility model discloses a throw formula computer keyboard light, its characterized in that: include: interior a plurality of sharp light source (1) of placing the computer frame in, straight line light source (1) is including drum (2), the one end of drum (2) is sealed there are convex mirror (3), into unthreaded hole (4) have been seted up on the lateral wall of drum (2), outside drum (2) it is just right in the computer frame it is provided with light source (5) to enter unthreaded hole (4), be provided with in drum (2) be used for with the light reflex of light source (5) is arrived reflector (6) on convex mirror (3), the other end of drum (2) is open -ended straight line light and goes out unthreaded hole (7), be provided with on the computer frame with straight line light goes out the elliptical aperture that unthreaded hole (7) are linked together, straight line light goes out unthreaded hole (7) towards keyboard setting. The utility model provides a pair of throw formula computer keyboard light places the computer frame in, in and does not influence the computer screen intensity.
Description
Technical field
The utility model relates to a kind of projection-type illuminating lamp for computer keyboard, belongs to ligthing paraphernalia technical field.
Background technology
Current illuminating lamp for computer keyboard is generally built in keyboard, there is keyboard price, if the faults such as button damage occur, needs entirety to scrap the problems such as keyboard.
Utility model content
The technical matters that the utility model solves is, provide a kind of be built in computer frame and do not affect the projection-type illuminating lamp for computer keyboard of computer screen brightness.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of projection-type illuminating lamp for computer keyboard, it is characterized in that: comprising: the some linear light source being built in computer frame, described linear light source comprises cylinder, one end of described cylinder is closed with convex mirror, the sidewall of described cylinder offers light well, just light source is provided with to described light well in described computer frame outside described cylinder, the reflective mirror for being reflexed to by the light of described light source on described convex mirror is provided with in described cylinder, the other end of described cylinder is the straight line light light hole of opening, described computer frame is provided with the elliptical aperture be connected with described straight line light light hole, described straight line light light hole is arranged towards keyboard.
Described light source comprises LED.
Described reflective mirror to be arranged at below described light well and to be that 40 ~ 50 degree of angles are arranged with described cylinder inner wall, and the length of described reflective mirror is less than the radius of described cylinder.
The material of described cylinder is lucifuge material.
Described lucifuge material comprises brown or black plastic.
The number of described linear light source is at least 3, is uniformly distributed on the top margin of described computer frame.
Each described linear light source is provided with shift knob on described computer frame, and some described linear light source are also provided with combined switch button on described computer frame.
A kind of projection-type illuminating lamp for computer keyboard that the utility model provides, the light of LED is irradiated on reflective mirror by light well, reflective mirror again light reflection on convex mirror, light after convex mirror all in the linear light radiation paralleled with cylinder on keyboard, for the night illumination of keyboard, and because the straight line light paralleled with cylinder shines directly on keyboard, therefore there is no light scattering on computer screen, the brightness of computer screen can not be affected; Be built in the setting of some linear light source of computer frame, the entirety avoiding the keyboard of traditional built-in illuminating lamp is scrapped, and greatly reduces the requirement to the keyboard that night uses.
