The energy-saving LED table lamp is simple in structure and convenient to use, can be supplied with power by mains supply or solar battery, and is environment-friendly and electricity-saving.
Description
Technical field
The present invention relates to a kind of light fixture, be specifically related to a kind of energy-saving LED desk lamp.
Background technology
The LED desk lamp is that light emitting diode is the desk lamp of light source with LED (Light Emitting Diode) exactly; LED is a kind of solid-state semiconductor devices; It can directly be converted into light to electricity; Have energy-saving and environmental protection, safe and reliable characteristics, had the new type light source of potentiality, represent the future of lighting engineering by good replacement in the 10 years futures traditional lighting utensil of industry.Because the power of LED illuminator is very low, we can effectively utilize existing solar battery technology.
Summary of the invention
Goal of the invention: the object of the present invention is to provide a kind of energy-saving LED desk lamp, the led light source of this desk lamp can be supplied power by the solar cell piece.
Technical scheme: a kind of energy-saving LED desk lamp of the present invention; Comprise base, support and be provided with the lamp holder of led light source; Be provided with alternating current-direct current transformer, constant current constant voltage driver element, solar cell, commercial power interface and automatic switchover controller in the said base; Said commercial power interface is connected with the ac power input end of said automatic switchover controller; Said solar cell is connected with the dc supply input of said automatic switchover controller; The ac power output of said automatic switchover controller is connected with the constant current constant voltage driver element through said alternating current-direct current transformer, and said constant current constant voltage driver element is connected with led light source, and the dc-battery output of said automatic switchover controller is connected with led light source through said constant current constant voltage driver element.
Further, said led light source is single the great power LED that is arranged on the circuit board.
For ease solar cell is taken off through sunlight charging, shown in solar cell be fastened in the bottom recesses of said base.
The present invention compared with prior art, its beneficial effect is: the present invention is simple in structure, and is easy to use, both can pass through mains-supplied, can pass through solar cell for supplying power, environmental protection and saves energy again.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
Be elaborated in the face of technical scheme of the present invention down, but protection scope of the present invention is not limited to said embodiment.
As shown in Figure 1; A kind of energy-saving LED desk lamp; Comprise base 1, support 2 and be provided with the lamp holder 3 of led light source; Said led light source is single the great power LED that is arranged on the circuit board, is provided with alternating current-direct current transformer, constant current constant voltage driver element, solar cell 4, commercial power interface and automatic switchover controller in the said base 1, and said commercial power interface is connected with the ac power input end of said automatic switchover controller; Said solar cell 4 is connected with the dc supply input of said automatic switchover controller; The ac power output of said automatic switchover controller is connected with the constant current constant voltage driver element through said alternating current-direct current transformer, and said constant current constant voltage driver element is connected with led light source, and the dc-battery output of said automatic switchover controller is connected with led light source through said constant current constant voltage driver element.
During use, can earlier solar cell 4 be taken off placement and charge in the sun, right be engaged in the bottom recesses of base 1; Earlier through solar cell for supplying power, if solar cell 4 electric energy exhaust can switch to mains-supplied well, simple in structure; Easy to use, environmental protection and saves energy.
As stated, although represented and explained the present invention that with reference to specific preferred embodiment it shall not be construed as the restriction to the present invention self.Under the spirit and scope of the present invention prerequisite that does not break away from the accompanying claims definition, can make various variations in form with on the details to it.
