Description
Technical field
The utility model relates to a kind of electric light, especially a kind of keyboard light.
Background technology
There is bright place, just have human civilization.Before tens thousand of year, the mankind have just understood keeps out the cold, roasts and throws light on the fire of nature.Before more than 3000 year, the mankind bring into use simple light fixture carrying fire, write civilized history.From coarse stone lamp to modern electric light, the branding in epoch has been stamped in the historical upheaval of light fixture, is also socioeconomic cultural epitome simultaneously.
Electric light is one of artificial light source, and it is electric current filament heating to being used for alight after incandescent state, is to produce hot principle according to electricity to make.Modern people wants work and study, evening to go home to like online to see a film, see news, chat etc. daytime, and particularly some university student, has a class back after dormitory evening, likes playing computer to the late into the night.Sometimes room-mate has slept also will continue to play and just must turn off the light, and has a rest to room-mate with interruption-free, at this moment there is no light, typewrites very inconvenient, begins a theatrical performance the words light of lamp too twinkling, still affects room-mate's rest.If there is a kind of keyboard light, adopt LED light source, small and exquisite slim, can be placed between computor-keyboard and screen as keyboard provides light, like this people to play computer night just more convenient.
Utility model content
In order to overcome the deficiency of above-mentioned existing product, the purpose of this utility model is to provide a kind of keyboard light, and it is made up of three lamp housings, between lamp housing, connects by metal contact, and inside is provided with LED lamp and light sensor, and right side is provided with USB plug.
In order to realize the technical scheme that the purpose of this utility model adopts be: a kind of keyboard light, is characterized in that: it is made up of lamp housing, switch, LED lamp, light sensor, USB plug, control circuit; Described lamp housing is square, have three, lamp housing right side, the left side is provided with two metal contact, inside is provided with two LED lamps, and middle lamp housing left side and right side are respectively provided with two metal contact holes, and inside is provided with two LED lamps and a light sensor, lamp housing left side, the right is provided with two metal contact, right side is provided with USB plug, and inside is provided with two LED lamps, and USB plug is provided with circular switch; Described LED lamp is square, has six; Described control circuit is made up of external power supply U, light sensor Q, K switch, LED lamp L.
The beneficial effects of the utility model are: by extinguishing of light-operated and switch control LED lamp, easy to use, and energy-conserving and environment-protective; Multiconductor connects, and, is convenient for carrying with use with dress.
