Abstract
The utility model discloses an automatic dimming desk lamp, which comprises a desk lamp body, a lampshade and a base, wherein an incandescent lamp and a fluorescent lamp are connected in parallel in the lampshade; a light intensity sensor is arranged in the lamplight irradiation range of the desk lamp on the surface of the desk lamp body; an output end of the light intensity sensor is connected with an input end of a singlechip; the output end of the singlechip is connected with an adjustable resistor and a switch; and a series circuit is formed by a power supply, the adjustable resistor, the switch and the parallel lamps. The light intensity sensor senses the changes of external light rays, and transmits signals to the singlechip; and the singlechip controls the adjustable resistor so as to adjust the brightness suitable for human eyes. When the light rays in the ambient environment are bright, the singlechip controls the switch to be connected with the incandescent lamp; and the singlechip controls the switch to be connected with the fluorescent lamp when the light rays in the ambient environment are weak. Therefore, the desk lamp gives out the brightness optimum for the human eyes according to the brightness of the external light rays so as to protect the human eyes. The automatic dimming desk lamp can also compensate the light intensity of the desk lamp by fully utilizing the light intensity of the ambient environment, reduces the energy consumption of the desk lamp, and reduces unnecessary waste.
Description
Technical field
The utility model relates to a kind of desk lamp, relates in particular to a kind of desk lamp with an automatic light meter.
Background technology
The desk lamp illuminations commonly used that is most people when reading and writing, the frequency of use is high, the time is long, and illuminating ray too by force or all make eye tired too easily causes eyesight decline, especially to the teenager.
Traditional desk lamp adopts fluorescent tube more, and long-term use makes eye tired easily.Existing lamp dimmer all is the moving adjustment of an armrest lighting tube brightness, can not be exactly adjusts the brightness of fluorescent tube according to the light intensity of the needs of human eye and surrounding environment, with optimal brightness a certain distance is arranged.
The utility model content
The purpose of the utility model provides a kind of desk lamp with an automatic light meter, can be according to the brightness of the light intensity adjustment fluorescent tube of the needs of human eye and surrounding environment.
To achieve these goals; The technical scheme of the utility model is: a kind of desk lamp with an automatic light meter, comprise desk lamp body, lampshade and base, and be parallel with incandescent lamp and fluorescent lamp in the said lampshade; Be provided with light intensity sensor in the desk lamp light-illuminating scope of desk lamp body surface; The output of said light intensity sensor and the input of single-chip microcomputer join, and the output of single-chip microcomputer and adjustable resistance and switch join, and power supply, adjustable resistance, switch and said parallelly connected lamp are formed series circuit.
Said switch is a single-pole double-throw switch (SPDT).
When ambient light was more intense, the said switch of said Single-chip Controlling was connected on the said incandescent lamp, and when ambient light was more weak, the said switch of said Single-chip Controlling was connected on the said fluorescent lamp.
Desk lamp is provided with the luminous intensity of acquiescence, and said Single-chip Controlling adjustable resistance changes electric current, thereby the adjustment lamplight brightness reaches the luminous intensity of acquiescence.
Light intensity sensor is experienced the variation of extraneous light, and signal is passed to single-chip microcomputer, Single-chip Controlling adjustable resistance, thereby the brightness of the suitable human eye of adjustment.When surrounding environment light was strong, the Single-chip Controlling switch was connected on the incandescent lamp, and when surrounding environment light was weak, the Single-chip Controlling switch was connected on the fluorescent lamp.Thereby the brightness that desk lamp sends the optimum human eye according to the power of extraneous light reaches the effect of protection human eye.The luminous intensity that also can make full use of surrounding environment compensates the luminous intensity of desk lamp, reduces the power consumption of desk lamp, reduces unnecessary waste.
Description of drawings

Fig. 2 is the know-why sketch map of desk lamp.
The specific embodiment
As shown in Figure 1, a kind of desk lamp with an automatic light meter comprises desk lamp body 1, lampshade 2 and base 3, is parallel with incandescent lamp 4 and fluorescent lamp 5 in the said lampshade 2, is provided with light intensity sensor 6 in the desk lamp light-illuminating scope on desk lamp body 1 surface.As shown in Figure 2; Incandescent lamp 4 and fluorescent lamp 5 parallel connections; The input of the output of light intensity sensor 6 and single-chip microcomputer 7 joins, and the output of single-chip microcomputer 7 and adjustable resistance 8 join with switch 9, and power supply 10, adjustable resistance 8, switch 9 and said parallelly connected lamp are formed series circuit.Said switch 9 is single-pole double-throw switch (SPDT)s.Desk lamp is provided with the luminous intensity of acquiescence, and light intensity sensor 6 can be experienced the luminous intensity in the desk lamp light-illuminating scope, and signal is conveyed to single-chip microcomputer 7, and single-chip microcomputer 7 control adjustable resistances 8 change electric current, thereby the adjustment lamplight brightness reaches the luminous intensity of acquiescence.When ambient light is more intense; Light intensity sensor 6 is conveyed to single-chip microcomputer 7 with signal; The said switch 9 of single-chip microcomputer 7 controls is connected on the said incandescent lamp 4; When ambient light was more weak, light intensity sensor 6 was conveyed to single-chip microcomputer 7 with signal, and the said switch 9 of single-chip microcomputer 7 controls is connected on the said fluorescent lamp 5.Thereby the brightness that desk lamp sends the optimum human eye according to the power of extraneous light reaches the effect of protection human eye.The luminous intensity that also can make full use of surrounding environment compensates the luminous intensity of desk lamp, reduces the power consumption of desk lamp, reduces unnecessary waste.
