Described light-inductive device is regulated the brightness of described bulb automatically for the induced environment light and according to environment bright; Described adjusting device is for the brightness of the described bulb of manual adjustments.
The desk lamp of above-mentioned energy adjustable desk lamp brightness, wherein, described light-inductive device comprises fixed value resistance and photo resistance, and described fixed value resistance is connected with parallel way with described photo resistance, and connects respectively described supply unit and described bulb by the same circuit;
When environment bright is partially dark, the photo resistance value increases, and total resistance value in parallel reduces, and by electric current, increases, and bulb brightness increases;
When environment bright is partially bright, the photo resistance value reduces, and total resistance value in parallel increases, and by electric current, reduces, and bulb brightness weakens.
The desk lamp of above-mentioned energy adjustable desk lamp brightness, wherein, described adjusting device comprises a rheostat, described rheostat connects respectively described supply unit and described bulb; When the brightness of automatic adjusting can't meet user's needs, the user reaches the purpose of manual adjustments bulb brightness by the resistance of standardsizing rheostat.
The desk lamp of above-mentioned energy adjustable desk lamp brightness, wherein, also comprise a switching device, and described switching device is positioned on described desk lamp pedestal, and is connected between described supply unit and described light-inductive device and described adjusting device; Described switching device by nip off or switch on power device and light-inductive device and adjusting device between the on off state that is connected to control described desk lamp that can adjustable desk lamp brightness.
The desk lamp of above-mentioned energy adjustable desk lamp brightness, wherein, described light-inductive device, described adjusting device and described switching device are incorporated in a control box, and described control box is installed on described desk lamp pedestal.
Beneficial effect of the present invention:
Provide automatic adjusting and manual adjustments two kinds of control modes; can automatically regulate according to environment bright the brightness of bulb; allow again the user to select the brightness of oneself liking by manual regulating device, range of choice is large and easy and simple to handle, and human eye is also played to certain protective effect.
The accompanying drawing explanation
Fig. 1 is the structural representation of the desk lamp of a kind of energy of the present invention adjustable desk lamp brightness;
Fig. 2 be the present invention a kind of can adjustable desk lamp the circuit diagram of light-inductive device of desk lamp of brightness.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the invention will be further described, but not as limiting to the invention.
Be illustrated in figure 1 the desk lamp of a kind of energy adjustable desk lamp brightness, comprise desk lamp pedestal 1, desk lamp body 2, bulb 3, light-inductive device 4, adjusting device 5 and supply unit 6; The desk lamp pedestal is positioned at desk lamp body below and supports the desk lamp body, and bulb is arranged on the desk lamp body; Light-inductive device and adjusting device are positioned on the desk lamp pedestal; Light-inductive device and adjusting device position be connection bulb respectively; Supply unit is respectively by light-inductive device and adjusting device connection bulb.
The light-inductive device is used for the induced environment light and automatically regulates the brightness of bulb according to environment bright; Adjusting device is for the brightness of manual adjustments bulb.
Also comprise a switching device in desk lamp, switching device is positioned on the desk lamp pedestal, and is connected between supply unit and light-inductive device and adjusting device; Switching device by nip off or switch on power device and light-inductive device and adjusting device between the on off state that is connected to control desk lamp that can adjustable desk lamp brightness; Light-inductive device, adjusting device and switching device are incorporated in a control box, and control box is installed on the desk lamp pedestal.
