The bed headlight
Technical field
The utility model relates to a kind of light fixture, particularly a kind of headlight.
Background technology
A traditional bed headlight is regulated the light size by knob mostly, like this, finishes watching postscript before people sleep, and put down first book, then specially removes to close or turn down this headlight, operates so cumbersomely, and the life comfortableness is inadequate.Traditional bedside lamp does not have the function of bookmark yet, and practicality is inadequate.And along with the fast development of modern sensor, LED light fixture industry is also flourish, and a bed headlight is necessary to introduce novelty design and obtains market.
The utility model content
The problems referred to above that exist in order to solve existing bed headlight, the utility model provide a kind of and need not specially to close or turn down light source, have the bed headlight of bookmark function.
The utility model adopts following technical scheme:
A kind of headlight, its lamp body is the house moulding, be provided with photo resistance on the upper surface, roof in house, the side in house is provided with the main light emission source by photo resistance control, be provided with the auxiliary light emission source by photo resistance control on the window of house front end, photo resistance control is when extinguish in the main light emission source, and the auxiliary light emission source point is bright.
Preferably, described roof is herringbone.
Preferably, described main light emission source and auxiliary light emission source are the LED lamp.
Technical conceive of the present utility model is: evening is when reading a book, open the power knob of a headlight, can under the bright light in main light emission source, read, when finishing watching book, as long as book is covered on the roof, page covers photo resistance, there is not light to impinge upon in the photo resistance, the resistance of photo resistance this moment increases rapidly, so extinguish in the main light emission source, the auxiliary light emission source is then lighted as mini light night and used.When reading next time, can directly take off books from the roof, photo resistance this moment has the light irradiation, and the resistance of photo resistance reduces rapidly, so the main light emission source point is bright, extinguish in the auxiliary light emission source, can continue like this reading of last time.
The beneficial effects of the utility model are: (1) is controlled lighting of main light emission source and auxiliary light emission source by photo resistance and is extinguished, and automaticity is high; (2) roof in house can be used as the bookmark use.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Drawing reference numeral: 1-roof; The 2-photo resistance; 3-main light emission source; The 4-window; 5-auxiliary light emission source.
The specific embodiment
With reference to Fig. 1: a kind of headlight, its lamp body is the house moulding, be provided with photo resistance 2 on 1 upper surface, roof in house, the side in house is provided with the main light emission source 3 by photo resistance 2 controls, be provided with the auxiliary light emission source 5 by photo resistance 2 controls on the window 4 of house front end, photo resistance 2 controls are when extinguish in main light emission source 3, and light in auxiliary light emission source 5.
Described roof 1 is herringbone.Like this, when the page that opens was buckled on the roof 1, the bookmark that roof 1 can be used as the sign page number used.
In the present embodiment, described main light emission source 3 and auxiliary light emission source 5 are the LED lamp.The brightness in main light emission source 3 can be read for books, and faint light is sent in auxiliary light emission source 5, uses as mini light night.
Evening is when reading a book, open the power knob of a headlight, can under the bright light in main light emission source 3, read, when finishing watching book, as long as book is covered on roof 1, page covers photo resistance 2, there is not light to impinge upon in the photo resistance 2, the resistance of photo resistance 2 this moment increases rapidly, so extinguish in main light emission source 3, auxiliary light emission source 5 is then lighted as mini light night and used.When reading next time, can be directly 1 take off books from the roof, photo resistance 2 this moment has the light irradiation, and the resistance of photo resistance 2 reduces rapidly, so light in main light emission source 3, extinguish in auxiliary light emission source 5, can continue like this reading of last time.
