Abstract
The utility model relates to a desk lamp, and the lighting brightness of which can be automatically adjusted. A light sensor switched on a control circuit is arranged on the existing desk lamp, and a control head of the light sensor is pointed to a light irradiated region on the front surface of the desk lamp. Integrative optical signals reflected by the surface are received, and then are fed back the control circuit to compare with setting surface illumination intensity. By adjusting the brightness of a disk lamp bulb, the integrative intensity of reflected light in the light irradiated region of the desk lamp is stabilized within some range, and ocular hygiene is ensured. The utility model has the characteristics of simple structure, low cost, and science.
Description
The utility model is a kind of desk lamp, the self-adjustable desk lamp of especially a kind of lamplight brightness.
Desk lamp is a kind of work, the essential product of study, the designs and varieties of desk lamp are various at present, on function, the desk lamp that existing lamplight brightness is adjustable, the nonadjustable desk lamp of lamplight brightness is also arranged, this gives people's life, work, study has brought very big convenience, but present existing desk lamp is all only considered stable or desk lamp energy-conservation of the brightness of light and brightness thereof on this major function in illumination, and the light-illuminating of having ignored desk lamp to the table top after, whether the illumination of table top just in time meets the eye hygiene of people when work or study, because in the actual use of desk lamp, the illumination of table top is except that the influence that is subjected to desk lamp light, also be subjected to surrounding environment light, the table top color, the influence of factors such as smooth degree, reflex to light in the human eye from table top after the only all of these factors taken together acting in conjunction that human eye is felt at last, have only this comprehensive reverberation to be stabilized in a certain value range, could guarantee under desk lamp, to work, use the health of eye during study, it is comfortable that human eye is also just felt, but present desk lamp does not all reach this requirement.
The purpose of this utility model provides a kind of simple in structure, and cost is not high, can regulate the desk lamp of the comprehensive reverberation illumination of table top automatically.
The utility model is made up of lampshade, bulb, cradling piece, pedestal and control circuit, bulb and lampshade are located at the cradling piece upper end, the cradling piece lower end is fixed on the pedestal, control circuit is located in the pedestal, on lampshade or cradling piece or pedestal, also be provided with a light sensor, sensor and control circuit conducting, the probe of sensor points to the light-illuminating district of the preceding table top of pedestal.
The utility model is owing to be provided with a light sensor with the control circuit conducting thereon, and light-illuminating district with table top before its probe sensing pedestal, therefore, sensor can receive the comprehensive luminous intensity from the table top reflection all the time and feed back to control circuit, compare with the table top illumination of setting,, guarantee that the comprehensive reverberation of table top is stabilized in a certain value range with the brightness of automatic adjusting desk lamp bulb, pleasant when making the thing of human eye on seeing table top, guarantee eye hygiene.
Accompanying drawing 1 is the utility model structural representation.
The utility model is described in further detail below in conjunction with accompanying drawing.As shown in the figure, the utility model is by lampshade (1), bulb (4), cradling piece (5), pedestal (9) and control circuit parts such as (6) are formed, bulb (4), lampshade (1) is located at cradling piece (5) upper end, cradling piece (5) lower end is fixed on the pedestal (9), control circuit (6) is located in the pedestal (9), on desk lamp, also be provided with a light sensor (2), light sensor (2) both can be located in the lampshade (1), also can be located at cradling piece (5) goes up or is located on the pedestal (9), no matter light sensor (2) is arranged on that position on the desk lamp, all must make its probe point to the light-illuminating district of the preceding table top of desk lamp pedestal (9), the received optical signal of light sensor (2) is only the comprehensive echo area on the table top like this, and regulate the brightness of bulb (4) automatically by control circuit (6), to keep on the table top comprehensive catoptrical intensity stabilization at a certain value range, but light sensor (2) optimum position is arranged on the inner surface of bulb (4) front lamp cover (1), because on this position, the most approaching comprehensive reflected light signal that enters human eye of comprehensive reflected light signal that light sensor (2) is received.
For making light sensor (2) can receive the reflected light signal in a zone of table top, rather than certain any signal, in light sensor (2) probe front convex lens (3) are set.
Because light sensor (2) receives the intensity of the comprehensive reflected light signal of table top and pops one's head in to the distance dependent of table top, therefore after setting table top illumination, the invariant position of relative table top should keep popping one's head in, could accurately determine the illuminance of table top, therefore cradling piece (5) is designed to rigid structure, and light sensor (2) other position component of desk lamp relatively is maintained fixed.
In order to make the utility model can satisfy multi-purpose illumination needs, the utility model also is provided with functional select switch (8) and manual light adjusting knob (7) on pedestal (9), functional select switch (8) can be provided with automatically, manually, gear such as disconnection, with function such as realize light modulation with an automatic light meter, manual respectively and turn off the light, manually light adjusting knob (7) just in time cooperates manual gear use in the functional select switch (8), but the light and shade of free adjustment light.
The utility model in use, activity such as read, write can be stirred functional select switch (8) makes it be in automatic gear, when making bulb (4) brightness variation that the comprehensive intensity of reflected light of table top is changed because of the surround lighting variation or because of voltage pulsation, light sensor (2) is about to this variation and is fed back into control circuit (6), and compare with the table top illumination of prior setting, automatically regulate the brightness of bulb (4) by control circuit (6), to keep the stable of the comprehensive intensity of reflected light of table top; When needing table top illumination brighter or darker sometimes, then can stir functional select switch (8), make it be in manual gear, make the signal of light sensor (2) not pass to control circuit (6), then can regulate the brightness that manual light adjusting knob (7) changes light, make the satisfied needs at that time of brightness of light, use very convenient.
Because the utility model just is provided with a photosensitive sensing circuit on the basis of existing desk lamp, so it is simple in structure, cost is not high yet.
Claims (5)
1, a kind of novel reading lamp, form by lampshade (1), bulb (4), cradling piece (5), pedestal (9) and control circuit parts such as (6), bulb (4), lampshade (1) are located at cradling piece (5) upper end, cradling piece (5) lower end is fixed on the pedestal (9), control circuit (6) is located in the pedestal (9), it is characterized in that on desk lamp, also being provided with a light sensor (2), this sensor (2) and control circuit (6) conducting, its probe points to the light-illuminating district of the preceding table top of pedestal (9).
