Abstract
The utility model discloses a self-adjusting desk lamp for eye protection. The desk lamp comprises a lamp shade, a lamp tube, a base, a switch and a retractable pipe, wherein, a photoelectric sensing electronic board used for sensing light energy of the ambient environment is arranged on the lamp shade; a transformer, an inner circuit board and a computer control panel which are connected in series are arranged in the base; the transformer is used for supplying direct-current power supply for the light source of the whole desk lamp; the inner circuit board is used for controlling the luminance of the desk lamp; the computer control panel is used for adjusting the current of the inner circuit board; the photoelectric sensing electronic board is connected with the computer control panel through a photoelectric sensing wire arranged in the retractable tube; and the lamp tube is connected with the inner circuit board through a main power source wire arranged in the retractable tube. By adopting the structure, the utility model has the benefits that the luminance of the desk lamp can be adjusted according to the change of the environment due to the adoption of the inner circuit board controlling the luminance of the desk lamp and the computer control panel adjusting the current of the inner circuit board, thereby alleviating eyestrain, and protecting vision.
Description
Technical field
The utility model relates to a kind of desk lamp, and the particularly a kind of desk lamp that can regulate eyeshield automatically belongs to daily life tools.
Background technology
The desk lamp kind of selling on the existing market is very many, comprises fluorescent lamp, incandescent lamp and light-emitting diode.When students study at ordinary times the time use desk lamp, can be because of the different injury of the bright degree eyesights of surrounding environment, we have this sensation at ordinary times: under the strong desk lamp of light, learn for a long time, arrive again light more weak local time, have at the moment and turn black and dusky; The bright desk lamp of a dozen lines that open the light will feel that eyes emit " Venus " in the dark.These eyes to us are very disadvantageous.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of desk lamp that can regulate eyeshield automatically, by adjusting the brightness of lamp along with environmental change and then adjusting asthenopia.
In order to solve the problems of the technologies described above, the utility model by the following technical solutions:
A kind of desk lamp that can regulate eyeshield automatically, comprise lampshade, fluorescent tube, base, switch and telescopic tube, described lampshade is provided with the photoelectric sensing electron plate of the light energy that is used for the perception surrounding environment, have the whole desk lamp light source of being used to of series connection in the described base transformer of DC power supply is provided, the bright degree interior circuit board and being used to of control desk lamp is adjusted the computer control board of the magnitude of current of interior circuit board, described photoelectric sensing electron plate links to each other with the computer control board by the luminous energy sense line that is arranged on telescopic tube, and described fluorescent tube links to each other with interior circuit board by the main power line that is arranged on telescopic tube.
Among the utility model embodiment, described fluorescent tube has the LED of several series connection.
The beneficial effects of the utility model:
1, adopt said structure, the bright degree interior circuit board by the control desk lamp and being used to is adjusted the computer control board of the magnitude of current of interior circuit board, makes desk lamp adjust the brightness of lamp and then adjust asthenopia along with environmental change, thus vision protection;
2, adopt DC driven LED fluorescent tube, do not have stroboscopic, and can be energy-conservation, safety, long service life.
Description of drawings
Fig. 1 is the structural representation of the selected embodiment of the utility model.
Among the figure 1, the photoelectric sensing electron plate, 2, lampshade, 3, fluorescent tube, 4, telescopic tube, 5, base, 6, plug, 7, lead, 8, switch, 9, transformer, 10, the computer control board, 11, interior circuit board.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further details, so that those skilled in the art better understand the utility model.
With reference to Figure of description 1, a kind of desk lamp that can regulate eyeshield automatically, comprise lampshade 2, fluorescent tube 3, base 5, switch 8, telescopic tube 4, lead 7 and plug 6, described lampshade 2 is provided with the photoelectric sensing electron plate 1 of the light energy that is used for the perception surrounding environment, have the whole desk lamp light source of being used to of series connection in the described base 5 transformer 9 of DC power supply is provided, the bright degree interior circuit board 11 of control desk lamp and being used to is adjusted the computer control board 10 of the magnitude of current of interior circuit board 11, described photoelectric sensing electron plate 1 links to each other with computer control board 10 by the luminous energy sense line that is arranged on telescopic tube 4, and described fluorescent tube 3 links to each other with interior circuit board 11 by the main power line that is arranged on telescopic tube 4.
Described fluorescent tube 4 has the LED of several series connection.
Operation principle of the present utility model is as follows;
How many photoelectric sensing electron plates 1 is delivered to its surperficial luminous energy according to indoor environment, the electric current of the coupled luminous energy sense line of may command, it is low promptly to work as surrounding brightness, then the luminous energy of photoelectric sensing electron plate 1 reception is few, electric current is just little in the luminous energy sense line, thereby can make the electric current throughput of computer control board 10 control interior circuit boards 11, thereby it is little to make interior circuit board 11 pass to lamp tube current by main power line, then the light that sends of fluorescent tube will be secretly a little to adapt to dark environment on every side; Otherwise it can realize that fluorescent tube also can be bright, and is to adapt to surrounding environment, convenient and practical along with ambient brightness increases.
