Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail, but execution mode of the present utility model is not limited thereto.
As shown in Figure 1 and Figure 2, a kind of automatic brightness-adjusting table lamp, comprise desk lamp housing and circuit, in described circuit, each element is placed in housing or on housing, comprise: 1, multi output rectifier, 2, controller, 3, control handle, 4, desk lamp light source, 5, light sensor, 6, desk lamp switch, wherein, input port, the mains supply of desk lamp switch 5 and multi output rectifier 1 are connected in series, and controller 2, control handle 3, desk lamp light source 4, light sensor 5 are connected in series from the different output ports of multi output rectifier respectively.Control handle 3, desk lamp light source 4, light sensor 5, desk lamp switch 6 are fixed on desk lamp outside, and multi output rectifier 1, controller 2 and the necessary circuit of forming circuit are placed in enclosure interior.
Generally, control handle 3 is placed in desk lamp casing neck; Described desk lamp light source 4 is placed in desk lamp case top; Described light sensor 5 is placed on desk lamp housing base with desk lamp switch 6.
The nominal input voltage of multi output rectifier 1 is 220V/50Hz, and output-current rating is not less than 1.5 times of described desk lamp light source 4.
Desk lamp light source 4 uses LED-based DC light source.
Light sensor 5 adopts many sensor port light sensor.
The data input/output port of multi output rectifier 1, control handle 3, light sensor 5 is all connected with the FPDP of controller 2, make they can and controller 2 between carry out data transmission, simultaneously, controller 2 can control multi output rectifier 1, changes the output voltage current value of different output port.
As Fig. 3, after user opens desk lamp switch 6, namely multi output rectifier 1 starts to power to controller 2, control handle 3, desk lamp light source 4, light sensor 5, and desk lamp lights.Now, the illumination brightness that 1 to n inductor of light sensor 5 senses is the background light of environment and superposing of desk lamp light, when light after a period of stabilisation, controller is set to default luminance by this brightness.After this, when the background light of environment changes, the illumination brightness that 1 to n inductor of light sensor 5 senses also changes thereupon, and the data recorded are submitted to controller 2, controller 2 thus control multi output rectifier 1, changes the electric energy that it provides desk lamp light source 4, thus changes desk lamp brightness, reach the object that total brightness (desk lamp brightness+background illumination brightness) is constant, realize the steady illumination of user.
When user needs brighter or darker lighting system, can manual adjustments control handle 3.When control handle 3 rotates, light sensor 5 quits work, and the position according to knob is changed brightness by desk lamp light source 1.When control procedure terminates, when knob 3 stops operating, light sensor 5 is resumed work, and makes desk lamp remain on new brightness constant always.
Compared with prior art, the utility model, owing to have employed said apparatus, makes desk lamp can need automatic regulating lightness according to user, realizes stable illumination.
These are only preferred embodiment of the present utility model; be not intended to limit protection range of the present utility model; therefore, all do within spirit of the present utility model and principle any amendment, equivalent replacement, improvement etc., all should be included within protection range of the present utility model.
