Description
Technical field
The utility model relates to field of illumination lamp technology, more specifically, relates to a kind of desk lamp that possesses mixed lighting pattern.
Background technology
Desk lamp be during people live, be used for illumination a kind of household electrical appliance, its operation principle is mainly that light is concentrated in a pocket, is convenient to working and learning.Wherein, LED desk lamp is to be the desk lamp of light emitting diode as light source take LED (Light Emitting Diode), compares traditional incandescent lamp, fluorescent lamp etc. and has energy-saving and environmental protection, safe and reliable feature.
In prior art, LED desk lamp part adopts great power LED to add optical lens, have that volume is little, power consumption is little, it is little to generate heat, life-span length, fast response time, safety low-voltage, good weatherability, good directionality, can be to advantages such as non-range of exposures impact, but because light intensity is stronger, illumination range is concentrated, but sometimes more dazzling, and the long-time rear easy fatigue of eyes is even hurt.Part desk lamp adopts many low-power LED array layouts to add the even light of diffuser plate, and it has, and light intensity is weak, illumination range feature widely, but also because illumination range is wide, brightness of illumination is lower, easily causes light pollution and the waste of non-irradiation area.In addition, in the prior art, also has a kind of desk lamp of multi-mode illumination, this kind of desk lamp is provided with large-power LED light bead and low-power LED lamp pearl simultaneously, two kinds of LED lamp pearls are by control circuit control, in the time of needs spotlighting, can select the LED lamp pearl of relatively high power to add the mode of operation of optical lens, otherwise, in the time of needs floodlighting, can select the LED lamp pearl of smaller power to add the mode of operation of diffuser plate, to meet the needs of different occasions, but in actual life, people are more and more diversified to the demand of light source mode, for example, at jewelry, the sales exhibition occasion of the jewellery such as gold vessel, people wish to apply adjustable spotlighting and two kinds of patterns of floodlighting on showcase simultaneously, it is honorable suitable to attract buyer that floodlighting pattern is covered with the surrounding of product, in the time that needing careful tasting product, buyer passes through to regulate the brightness ratio of two kinds of light sources, product can be examined in spotlighting pattern, again for example indoor, people can working and learning under spotlighting pattern, can under floodlighting pattern, make again indoorly can obtain soft lighting atmosphere, but because above-mentioned two kinds of light source mode are all to control respectively light on and off, and brightness can not regulate, or be that light source is certain power, pattern is single, can not meet people's multiple demand, therefore it is restricted that prior art has larger use, cause the using adaptability deficiency of LED desk lamp.
Summary of the invention
The utility model is intended to solve the problems of the technologies described above at least to a certain extent.
The purpose of this utility model is to provide a kind of using adaptability, easy to use desk lamp that possesses mixed lighting pattern of improving.
A kind of desk lamp that possesses mixed lighting pattern, comprise lampshade, drain pan, control circuit, described drain pan is located on lampshade, described drain pan is provided with substrate, described substrate upside is provided with radiator, downside is provided with the LED lamp pearl of two kinds of different capacities, in described control circuit, be provided with LED light modulator, described two kinds of LED lamp pearls are electrically connected in respectively the output of LED light modulator and with different intensity of illumination work, preferably, electric current output intensity/the pulse width of at least two outputs of described LED light modulator is adjustable respectively, for reaching different intensities of illumination, LED light modulator can arrange the output that two kinds of electric current output intensities vary in size according to prior art, or utilize PWM light regulating technology, two kinds of outputs that pulse width is different are set, by regulating LED light modulator, two output end current intensity/pulse widths in light modulator are arranged in pairs or groups by a certain percentage, therefore, the LED lamp pearl of two kinds of different capacities both can be worked simultaneously, also can regulate respectively by LED light modulator the brightness ratio of two kinds of LED lamp pearls, when needs spotlighting is while being main, can increase relatively high power LED lamp pearl intensity of illumination and coordinate optical lens work, when needs floodlighting is while being main, can increase smaller power LED lamp pearl intensity of illumination and coordinate diffuser plate work, therefore make desk lamp possess the pattern of multiple mixed lighting, to cater to the needs of different occasions.Therefore, the utlity model has wider using adaptability, same desk lamp has different mixed lighting patterns, is user-friendly to.
Further, described LED lamp pearl comprises at least one large-power LED light bead and at least one low-power LED lamp pearl.Because great power LED and low-power LED are the general technical terms of those skilled in the art, here its definition is no longer repeated.Wherein large-power LED light bead is for the occasion of spotlighting, and being applicable to fine work or head of a bed reading does not affect other people's state such as sleep; Low-power LED lamp pearl for the occasion of floodlighting, for example, is generally write and common duty.
Preferably, described large-power LED light bead downside is provided with optical lens, described low-power LED lamp pearl downside is provided with diffusion sheet, optical lens is mainly used in the optically focused of LED cold light source series of products, leaded light, can be according to the angle design distribution curve flux of different LED emergent light, by increasing optical reflection, reduce light loss, improve light efficiency.The light that diffusion sheet can make LED lamp pearl send evenly appears.
Because the illuminance of great power LED is strong, illumination range is concentrated; The illuminance of low-power LED is weak, illumination range is extensive, and therefore preferably, described large-power LED light bead is located at the central authorities of substrate, and described low-power LED lamp pearl is arranged around large-power LED light bead.
In one embodiment, between the LED chip of different capacity, be provided with decorative element for lamp, work to intercept two kinds of light sources, and improve aesthetic property and the competitiveness of product, more can attract consumer's sight.
The beneficial effects of the utility model are: the LED lamp pearl of two kinds of different capacities of the utility model both can be worked simultaneously, also can regulate respectively by LED light modulator the brightness ratio of two kinds of LED lamp pearls, when needs spotlighting is while being main, can increase relatively high power LED lamp pearl intensity of illumination and coordinate optical lens work, when needs floodlighting is while being main, can increase smaller power LED lamp pearl intensity of illumination and coordinate diffuser plate work, therefore make desk lamp possess the pattern of multiple mixed lighting, to cater to the needs of different occasions, the utlity model has wider using adaptability, same desk lamp has different mixed lighting patterns, be user-friendly to.
