Abstract
A light-emitting diode desk lamp comprises at least one light-emitting diode, a driving circuit, a desk lamp shaped bracket and an outer shell, an electrical connector, at least one switch, and a light-adjusting device. The utility model has the advantages of continuously steady adjusting light from 0 percent to 100 percent, direct current working, having no stroboflash when luminescent, adjusting light color tone according to season and personal preference such as changing cold white color to warm white color. Besides, the utility model also has the advantages of even light illuminance on the useful lighted surface, long working life, no pollution as fluorescent lamp, no electromagnetic disturbance, and firm property, suitable for illuminating instead of present incandescent lamps and fluorescent lamps.
Description
Technical field
The utility model relates to a kind of LED desk lamp, can replace existing incandescent lamp, fluorescent lamp desk lamp, is used for illumination.
Background technology
The desk lamp of prior art is mostly with incandescent lamp or fluorescent lamp as light source.The former continuously light-adjustable, but when low-light level very luminous instability, and light efficiency is low, the life-span short; It is short that the latter is difficult to continuous light tuning, life-span, and mercury is arranged in the lamp, damaged or abandon and pollute the environment.The tone that the two all can't change light, the light that is shone table top distributes all inhomogeneous.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of above-mentioned existence, provide a kind of can from 0 to 100% continuous light tuning, DC operation, luminous no stroboscopic, luminous tone can be by season and each one hobby free adjustment, the illuminance of face to be illuminated is even, the life-span long, the mercury of no fluorescent lamp evil, no electromagnetic interference, solidification light source, firm also can be designed to plate novel light-emitting diode desk lamp.
The purpose of this utility model is achieved in that it includes a desk lamp shape support and shell, electric connector, driver and a switching device, it is characterized in that at least one light emitting diode is installed on desk lamp shape support and the shell, this light emitting diode is connected with driver.
Described light emitting diode is installed on the substrate, has conductor wire to link to each other with driver on the substrate, and the switching device that links to each other is switch and light modulating device.
Described light emitting diode is for more than at least two, each light emitting diode by in parallel and or the mode of series connection interconnect and form.
Described light emitting diode is that the light emitting diode of identical illuminant colour is formed.
Described light emitting diode is that the light emitting diode of different colors is formed, and is connected with at least two light modulating devices independently separately with it respectively.
Described LED front area light output window is provided with just like optical sheets such as diffusing panel or lenslet array plates, makes the light of desk lamp outgoing soft, even.
The light emitting diode of LED desk lamp of the present utility model is by DC operation, luminous no stroboscopic, but vision protection.Change the electric current through light emitting diode, can regulate the brightness of lamp, brightness can from 0 to 100% steady light modulation, and can rest under arbitrary brightness and stably work.
The utility model Mining is with the light emitting diode of the less smooth angle of emergence, the arranged distribution of a plurality of light emitting diodes, can be by the requirement design of face to be illuminated Illumination Distribution, for example be designed to that illuminance evenly distributes on useful illuminated, be that face to be illuminated centre light emitting diode is less, and directive light emitting diode at a distance is more.
LED desk lamp of the present utility model is compared with incandescent lamp, the fluorescent lamp desk lamp of prior art, having can from 0 to 100% steady light modulation, the luminous no stroboscopic of DC operation, can like that tone, the face to be illuminated illuminance of regulating light are even by season and each one, life-span length, no mercury pollution, no electromagnetic interference, total solidsization, advantage such as firm.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, further set forth operation principle of the present utility model and embodiment.Fig. 1 is the structural representation of LED desk lamp of the present utility model.1 is at least one light emitting diode among Fig. 1, and 2 is the support and the shell of desk lamp shape, and 3 is the drive circuit of light emitting diode, and its end links to each other with external power through electric connector 4, and its output links to each other to light light emitting diode with luminous two pipes 1 through Table lamp stand 2.5 is the switch and the light modulator of lamp.Light emitting diode is installed on the substrate 6.Conductor wire 7 is arranged on the substrate 6, the output of each light emitting diode with drive circuit 3 is linked to each other.8 is the shell of desk lamp.In order to make output light softer and even, on the light output window of desk lamp, an optical sheet 9, for example diffusing panel, lenslet array plate etc. arranged.
Described light emitting diode 1 can be the light emitting diode of series of identical illuminant colour, for example is the light emitting diode of a series of whites; Also can be the light emitting diode of a series of different colors, regulate the brightness of not homochromy light emitting diode respectively, can change the photochromic of output light.A series of cold whites or warm-white light-emitting diode are arranged example and another series is red, orange, the light emitting diode of Lan Se or other look, change the brightness of light emitting diodes such as red, orange or blue look, can change the colour temperature of whole lamp output light, for example change to warm white or opposite by cold white; Thereby the colour temperature that can allow the user regulate light with the different of hobby and season by the needs of oneself.
Described at least one light emitting diode, when a plurality of light emitting diode was arranged, each light emitting diode can have the mode of a plurality of light emitting diode parallel connections, multirow series connection to connect by every row, and when having minority to damage in the light emitting diode, whole lamp still can operate as normal.
Described external voltage can be DC voltage or electric main; When using electric main, alternating voltage becomes through driver to be added to behind the voltage of suitable amplitude makes lumination of light emitting diode on the light emitting diode.The electric current of regulating the light emitting diode of flowing through with described light modulator can be regulated the brightness of lamp.Light modulator can be a potentiometer that has a switch.Because light emitting diode can work under any electric current below the highest permission electric current, thereby the brightness of lamp can from 0 to 100% steady light modulation, and can be under arbitrary brightness steady operation.Described driver 3 can be installed on the base or on the substrate 6.
When described light emitting diode had more than two kinds illuminant colour and need regulate brightness respectively, described desk lamp can have two above light modulators, shown among Fig. 15 and 10.
Described desk lamp, in order to obtain uniform illumination being arranged at plane of illumination, the described light emitting diode available light angle of emergence is less, light emitting diode for example ± 30 ° requires to be installed on the substrate 6 according to degree uniformly, promptly central nearly face to be illuminated place, light emitting diode can be less, and directive face to be illuminated light emitting diode at a distance is more.
The support of described desk lamp and shell 2 can be designed to multi-form and shape, also can be designed to foldable type, console mode, fixture type etc.; Also can be combined into the combined LED desk lamp with some articles for daily use, for example calculator, clock, thermometer, radio etc.
The related know-how of LED desk lamp that the utility model is introduced is that the general personnel of this specialty are familiar with, and therefore as long as understand content of the present invention, can do various forms of variations and replacement.
