The utility model provides a pair of dustless type throws formula computer keyboard light, intelligence is opened the baffle and is made in the difficult entering computer frame of dust.
Description
Technical field
The utility model relates to a kind of dustless type 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 dustless type projection-type illuminating lamp for computer keyboard of computer screen brightness; Further, the utility model provides a kind of dust not easily to enter computer frame, and baffle plate is light-operated, the dustless type projection-type illuminating lamp for computer keyboard of intelligent opening.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of dustless type 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, be provided with baffle plate between described elliptical aperture and straight line light light hole, described baffle plate is provided with switch.
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.
Described switch comprises light-operated switch.
Described baffle plate is close to described elliptical aperture inwall and is arranged, and described switch-linear hybrid is in the opposite face of described baffle plate and described light source 5.
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.
The one that the utility model provides dustless type projection-type illuminating lamp for computer keyboard, 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; The setting of baffle plate, for airtight elliptical aperture during without the need to opening linear light source, makes dust not easily enter in computer frame; The setting of light-operated switch, makes baffle plate be light-operated, when needs keyboard illumination opens LED, light is irradiated on light-operated switch, then baffle plate is opened automatically, when closing LED, light stops being irradiated on light-operated switch, then baffle plate is closed automatically, realizes the intelligent opening of baffle plate.
