Abstract
The utility model relates to a commonly-used computer input device-a keyboard, in particular to a keyboard with a folding lighting lamp. The keyboard comprises a keyboard, a cuboid cavity, a cover plate, an LED (light-emitting diode) lamp, a hinge, a resistor and a USB (universal serial bus) plug. The characteristics of the keyboard are as follows: the cuboid cavity is arranged at the left upper part of the keyboard, a folding cover plate is arranged above the cuboid cavity, the LED lamp is arranged under the cover plate, and the folding cover plate is connected onto the computer keyboard through the hinge. The circuit connection is as follows: the LED lamp is connected with a current-limiting protection resistor in series; both ends of the LED lamp are respectively connected with the USB plug to form a loop. The advantages of the keyboard are as follows: the structure is simple, the material cost is low, and the keyboard is convenient to use. Other lamps are not needed to turn on under dim light, the LED lamp under the cover plate is slightly turned on for using; meanwhile, when the LED lamp is out of use, the cover plate is closed to totally hide the LED lamp, so that the appearance cannot be affected and the electricity and energy can be saved.
Description
Technical field
The utility model relates to computer input equipment keyboard commonly used, specifically a kind of keyboard that carries folding illuminating lamp.
Background technology
Now, no matter computer that people use or when importing with keyboard in the life under the situation of dim light, is to be used for working, to go to school, and most people can touch system.Manuscript imported in the various letters that need lamp seeing on the surface of keyboard to be marked, to reduce error originated from input.Under the environment that has, use daily desk lamp that inconvenience is arranged.As on numerical control device, when perhaps family surfs the Net night, use light fixture commonly used can influence other people and have a rest.Therefore, invent a kind of keyboard that carries folding illuminating lamp, can increase work efficiency greatly.
Summary of the invention
The purpose of this utility model is at the defective of existing keyboard and illumination incoordination, and a kind of keyboard that carries folding illuminating lamp is provided, and solves the inconvenience of people when using computer.
The technical solution of the utility model is achieved in that a kind of keyboard that carries folding illuminating lamp; it comprises keyboard, rectangular parallelepiped cavity, cover plate, LED lamp; hinge, resistance and USB plug; it is characterized in that: be provided with a rectangular parallelepiped cavity on the keyboard upper left side; a folding cover plate is installed in rectangular parallelepiped cavity top; cover plate is installed the LED lamp down; folding cover plate is connected on the computor-keyboard by hinge; its circuit connects; the LED lamp is connected with current-limiting protection resistance, and its two ends is connected to USB plug respectively and forms the loop.
The beneficial effects of the utility model and advantage are: simple in structure, the cost of material is low, easy to use.Do not need to open in addition other light fixture when dim light, start the LED lamp under the folding cover plate gently, the USB plug of plugging on the keyboard can be used, and time spent lid lower cover is then not hiding fully, does not affect the appearance energy saving.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a circuit diagram of the present utility model.
Embodiment
The utility model will be further described below in conjunction with accompanying drawing.
As shown in Figure 1; a kind of keyboard that carries folding illuminating lamp; it comprises keyboard 1, rectangular parallelepiped cavity 2, cover plate 3, LED lamp 4; hinge 5, resistance 6 and USB plug 7; it is characterized in that: be provided with a rectangular parallelepiped cavity 2 on keyboard 1 upper left side; a folding cover plate 3 is installed in rectangular parallelepiped cavity top; cover plate is installed LED lamp 4 down; folding cover plate is connected on the computor-keyboard by hinge 5; circuit connects as shown in Figure 2; LED lamp 4 is connected with current-limiting protection resistance 6, and its two ends is connected to USB plug 7 respectively and forms the loop.
During use, only need start the LED lamp under the folding cover plate 3 gently, the USB socket that USB plug 7 is inserted on the computer housing obtains 5V voltage and makes LED lamp luminous lighting, realize providing the computer input required lighting source for people easily at any time, thereby solved under dim light, when not opening other electric light, also can the handled easily computer, increase work efficiency.
