Abstract
The utility model provides a high-power LED table lamp, which comprises an LED lamp, a plano-convex lens or an amplifier, a battery box capable of containing a plurality of batteries, a direct current power, a power jack for containing the output end pin of the direct current power, a phone wire jack capable of containing a phone wire plug, and an USB interface capable of connecting external USB interface for supplying power. The LED lamp is arranged at the focus of the plano-convex lens. The high-power LED table lamp, emitting no scattered light, sends environmental-protection light; and the diaphragm is an even circle which can be supplied power by the battery, the alternating electricity, the phone wire or the external USB device, promising the table lamp useful when power off; besides, supplying power by phone wire can save electric energy.
Description
Technical field
The utility model relates to a kind of desk lamp, relates in particular to a kind of light environmental protection, aperture is uniform circle, can select to power with battery, commercially available alternating current, telephone wire or any mode of circumscribed USB equipment, does not worry the high power LED desk lamp that has a power failure.
Background technology
High power LED desk lamp has been arranged in the market, but these desk lamps all are only to have only illumination functions, compare with traditional incandescent lamp, the desk lamp of fluorescent lamp, except its light source kind changes, other not too big differences.Though to have broken through the power consumption of conventional incandescent, fluorescent lamp big for these high-powered LED lamps at present, the shortcoming of not environmental protection of light, but its LED lamp still is and common planar glass or plastic cement combination, can not send aperture is the light shape of a clear uniform circle, and generally have only the single powering mode of grafting dc source, just can't use desk lamp if having a power failure.
The utility model content
The technical problems to be solved in the utility model is: overcome existing high power LED desk lamp light source and utilize insufficient, light shape tradition does not have characteristics, the problem of having only the single powering mode of dc source, it is a uniform circle that a kind of light source, light environmental protection, aperture of making full use of is provided, can select to power, not worry the high power LED desk lamp that has a power failure with battery, commercially available alternating current, telephone wire or any mode of circumscribed USB equipment.
In order to solve the problems of the technologies described above, the utility model proposes following technical scheme: a kind of high power LED desk lamp, it comprises that a LED lamp, a planoconvex spotlight, can install the telephone line jack that supply hub, that the battery case of some batteries, a direct current power supply, be used for admitting the output pin of this dc source can be admitted telephone line plug, the USB interface that can circumscribed USB equipment powers; This LED lamp is installed in the focal position of this planoconvex spotlight.
Wherein, this high power LED desk lamp also comprises a housing, and this LED lamp and planoconvex spotlight all are fixed on this housing.
In another technical scheme, replace this planoconvex spotlight with a magnifying glass.
Wherein, this high power LED desk lamp also comprises this LED lamp luminous intensity of control and the desk lamp switch that extinguishes.
Wherein, carried out the circuit connection between this LED lamp, battery case, dc source, supply hub, telephone line jack, USB interface, the desk lamp switch.
The utlity model has following beneficial effect: this LED lamp is installed in the focal position of this planoconvex spotlight, and the light that this LED lamp sends is reflected into parallel light by this planoconvex spotlight and penetrates, therefore, astigmatism can not take place in this desk lamp, the light environmental protection of sending, light shape are uniform circles; This desk lamp has been installed these parts of battery case, dc source and supply hub, telephone line jack and USB interface, can select to power with battery, commercially available alternating current, telephone wire or any mode of circumscribed USB equipment, do not worry having a power failure and to use desk lamp, and also can save electric energy with phone-line-powered.
Description of drawings
Fig. 1 is the schematic diagram of the utility model high power LED desk lamp.
The specific embodiment
See also Fig. 1, a kind of high power LED desk lamp, it comprises a housing (figure does not show), a LED lamp 2, a planoconvex spotlight 3, a battery case 4, a direct current power supply (figure does not show), a supply hub 6, a telephone line jack 7, a desk lamp switch 8, a USB interface 9.
This LED lamp 2 and planoconvex spotlight 3 all are fixed on this housing.This LED lamp 2 is installed in the focal position of this planoconvex spotlight 3, so the light that this LED lamp 2 sends is all reflected into parallel light ejaculation by this planoconvex spotlight 3.Therefore, astigmatism can not take place in this desk lamp, and the aperture that sends is a uniform circle, can install some batteries (figure does not show) in this battery case 4, electric energy is provided for this desk lamp.
This dc source converts commercially available alternating current the direct current of low pressure to, is supplied to this desk lamp to use.
This supply hub 6 is used for admitting the output pin (figure does not show) of this dc source.
Can admit existing telephone line plug (figure does not show) in this telephone line jack 7, electric energy is provided for this desk lamp, realization technology wherein also is a prior art well-known to those skilled in the art.
This desk lamp switch 8 is controlled the luminous intensity of these LED lamps 2 and is extinguished.
This USB interface 9 can be powered (figure does not show) by circumscribed USB equipment
Carried out the circuit connection between above-mentioned LED lamp 2, battery case 4, dc source, supply hub 6, telephone line jack 7, desk lamp switch 8 and the USB interface 9, can realize optionally allowing powered battery, perhaps the dc source commercially available alternating current of pegging graft is powered, perhaps allow telephone wire power, perhaps allow circumscribed USB equipment power, these power supply modes and selection power supply all are common technique of the prior art, do not repeat them here.This patent mainly is conceived to and can optionally powers to desk lamp with above-mentioned four kinds of modes.
In the utility model, this LED lamp 2 is installed in the focal position of this planoconvex spotlight 3, and the light that this LED lamp 2 sends is reflected into parallel light by this planoconvex spotlight 3 and penetrates, and therefore, this desk lamp astigmatism can not take place, and the light shape of sending is a clear uniform circle; This desk lamp has been installed battery case 4, dc source and supply hub 6, telephone line jack 7 and USB interface 9 these parts, can select to power with battery, commercially available alternating current, telephone wire or any mode of USB, do not worry having a power failure and to use desk lamp, and also can save electric energy with phone-line-powered.
Above-mentioned is first embodiment, and as the variant embodiment of the foregoing description, this planoconvex spotlight 3 can be replaced with a magnifying glass, can realize purpose and effect that first embodiment is identical equally.
