Description
Technical field
But the utility model relates to the energy-saving desk lamp of the omnidistance continuous light tuning of a kind of wide region, especially a kind of not only do not had stroboscopic but also can be in whole service life process, whenever all can be transferred to the ultralong-life energy-saving desk lamp of the most comfortable brightness; Be used for illumination.
Background technology
The desk lamp of prior art is made light source with hot-cathode fluorescent lamp mostly.It has no stroboscopic, luminous efficiency height, generally greater than 501m/W, the colour rendering index advantages of higher now is widely used.But the only approximately several thousand hours life-span of its fluorescent tube, every switch once, will shorten about 1--3 hour service life, the desk lamp switch number of times is more, is generally half a year to one year the service life of fluorescent tube, the maintenance trouble, has to whole desk lamp is abandoned because of the fluorescent tube that can't buy same model sometimes; Simultaneously, this desk lamp also is difficult to continuous light tuning, even with the circuit light modulation of complicated high price, brightness must arrive first near peaked brightness when turning on light, and dims then, and its minimum brightness can only be transferred to about 20% of high-high brightness, can not turn on lamp in its minimum brightness or intermediate luminance, be difficult to promote.
We know, as the brightness and the no stroboscopic no less important of desk lamp, the most comfortable, light is too bright or too secretly all be unfavorable for vision protection; And the brightness of this most comfortable is relevant with service time, the ambient brightness when using, user's age and the character of eyesight situation, photographed object or reading thing etc.But this just requires outstanding desk lamp must possess the function of the omnidistance continuous light tuning of wide region, does not possess this function and have the hot-cathode fluorescent lamp desk lamp now.Secondly; the luminosity of fluorescent lamp all can be decayed with the increase of service time; if the brightness of a new time spent of desk lamp just in time; so at the use some months or after half a year, more than the brightness decay 30% even 50%; at this moment lamp brightness is just too dark; and can't heighten brightness, if use then is unfavorable for vision protection reluctantly.In addition, the brightness of fluorescent lamp when room temperature is low, the brightness meeting obviously descends, at this moment it also can't heighten brightness.Promptly can not accomplish to can be adjusted to all the time brightness the most comfortable, that help vision protection most in the process in whole service life.
Cold-cathode fluorescence lamp since have the life-span long, the switch number of times influences lamp life-span, light modulation easily hardly, dimming scope is wide, luminous efficiency is high, advantage such as energy-conservation, be well suited for and make tunable optical desk lamp etc.The light-dimming method of the cold-cathode fluorescence lamp desk lamp of prior art has two kinds, and the one, the angle of flow of regulating the input AC electricity with controllable silicon comes light modulation; The 2nd, the pulse width modulation method is promptly regulated the pulse duty factor of fluorescent tube driving voltage or is removed to modulate a high-frequency impulse with the pulse of a lower frequency.But these methods come with some shortcomings, and even want the wide region continuous light tuning, just can not accomplish luminous no stroboscopic, and are promptly unfavorable for vision protection; The optical frequency that has 100Hz or hundreds of Hz with the pulse width modulation method is dodged, and also has noise simultaneously.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, but and provides a kind of energy-saving desk lamp of the omnidistance continuous light tuning of wide region of two key elements that possesses luminous no stroboscopic simultaneously, can be adjusted to the brightness of the most comfortable in whole service life in the process all the time.It includes at least one cathode fluorescent tube and fixture thereof, lampshade, light reflecting device, Table lamp stand and base, at least one driver, at least one switch and at least one light modulation and/or ager, electric connector and electric connection line thereof; Described at least one cathode fluorescent tube is " U " type, many " U " type, many " U " bridge type, list or double helical form, dull and stereotyped list or double helical form fluorescent tube; The design power of described fluorescent tube is 1.5-4 a times of initial normal illumination power; Described driver includes adjustable Switching Power Supply and at least one DC/AC converter of DC voltage height of at least one output; Described DC/AC converter the direct current of Switching Power Supply output be transformed into the alternating current that is suitable for described cathode fluorescent tube work, to light described at least one cathode fluorescent tube; Regulate the DC voltage of at least one Switching Power Supply output height, can regulate the brightness output of described desk lamp, but the omnidistance continuous light tuning of wide region, be behind the turn-on lamp power supply, desk lamp brightness can be from the 0-15% of a certain minimum of a value, for example high-high brightness, be adjusted to high-high brightness continuously, promptly 100%, and can stop therebetween arbitrary brightness stability work; Otherwise, from 100% 0-15% that is adjusted downward to minimum of a value, for example high-high brightness, also be continuously adjustable, also can stop therebetween arbitrary brightness stability work.At least one switch of described driver can be installed together with at least one light modulation brightness and/or photochromic device, also can be installed separately; The former opens and closes and passes through the brightness minimum of a value, and the latter then can open and close in the brightness of any setting.Simultaneously and since the design power of fluorescent tube be initial normal illumination power 1.5-4 doubly, even the brightness of fluorescent tube decays with the increase of service time or because of room temperature descends than the low-light level meeting, desk lamp still can be adjusted to the brightness of needed the most comfortable.In addition, desk lamp of the present utility model, most of service time are the parts that works in the lamp design power, and the long service life of fluorescent tube and drive circuit still can be adjusted to the brightness of needed the most comfortable after the lighting tube brightness decay, make the life-span of lamp longer.Simultaneously, the output of the light of desk lamp of the present utility model is essentially linear relationship with lamp power, and full design power or part that lamp works in lamp are all energy-efficient.
