many table lamps in the prior art are suitable for incandescent lamps, energy-saving lamps and LED light sources, and are not suitable for electrodeless lamp light sources, infrared irradiation light sources, spectrum irradiation sources and other special occasions with high requirements on heavy lamp holders;
the prior art incandescent lamp light source desk lamp is reduced in use because the incandescent lamp does not save energy;
in the prior art, the energy-saving lamp is used less and less because the energy-saving lamp also has stroboflash and radiation;
in the table lamp with the LED light source in the prior art, the problems of eyesight and health damage caused by blue light, stroboflash, radiation, dazzling light, color cast and the like exist in the LED light source, and the illumination quality is influenced due to low color rendering property. The world health organization WHO loving eyes association publishes: more than 30000 worldwide are blinded each year from 2006 to 2008 due to blue light radiation. According to the data display of the ophthalmology conference of the Chinese medical society: among 4.2 hundred million net citizens in China, 63.5% of net citizens have eye diseases with different degrees such as visual deterioration, cataract, blindness and the like due to blue light and radiation. The existing research shows that the long-time exposure in high-intensity blue light in one day aggravates the retinal macular region diseases, causes the eyeground injury after cataract operation, causes blurred vision and glare, inhibits the secretion of melatonin, disturbs sleep and increases the incidence rate of serious diseases of human bodies. In the conventional white light LED light source for illumination, after the blue light LED excites the yellow fluorescent powder, white light is generated, the spectral curve of the white light is not smooth, particularly, the peak value of the blue light wave band is obviously higher than that of natural light or an incandescent lamp, the obtained white light spectrum has more blue light weight, and the over-strong blue light has harm to human eyes; in recent years, LED illumination light sources widely replace conventional illumination light sources as desk lamp light sources.
The desk lamp in the prior art is mostly of a single cantilever beam type structure, is only a simpler structure for balancing the gravity moment of a lamp holder and the moment of a lamp holder, and can only adapt to light point light sources with lighter mass, such as incandescent lamps, LED light sources and occasions with low requirements on span height;
in the prior art, the desk lamp based on the balance rod principle, the desk lamp based on the pulley device and the desk lamp with weights cannot meet the requirements of rapidness, simplicity, low cost and complicated professional environment due to complicated adjustment;
the invention provides a new application technical scheme, which can widely meet the requirements of occasions needing background light and long-distance illumination for long-time use, such as: the system is used for counteracting professional background light of blue light of a computer screen, repairing cultural relics and ancient sites with high requirements on color rendering, distinguishing colors of photographic lighting, food materials, cloth, paper and printing, maintaining equipment and protecting health, and meeting certain high requirements and complex environments;
the invention relates to a special desk lamp which is placed stably, is convenient to adjust the illumination height and distance quickly, and is particularly suitable for special purposes such as elimination of the problems of damage to vision and health caused by blue light, stroboflash, radiation, glare, color cast and the like, more healthy and high-color-rendering electrodeless lamps compared with natural sunlight, infrared treatment light sources with larger weight, spectrum treatment instruments and the like.

6. The linkage mechanism of the desk lamp as claimed in claim 1, wherein the linkage mechanism base is a thick circular plate which has a circular cut perpendicular to the horizontal plane and is installed on the lamp holder with the bracket and has an outer circular surface, the circular plate is provided with hinge D holes and hinge a holes arranged up and down, the circular plate takes the hinge a holes as a circle center and takes a linear distance equal to or slightly greater than the axis of the hinge a of the balance hinge plate and the circular arc surface of the clamper as a radius, the outer circular surface of the circular plate is used as a locking action surface of the clamper, the connecting line of the axis of the hinge D hinge a on the linkage mechanism base is perpendicular to the horizontal plane, the horizontal circle of the linkage mechanism base is cut below the circle, and the linkage mechanism base is connected with the lamp holder with the bracket through.
7. The linkage mechanism of the desk lamp as claimed in claim 6, wherein the balance handle of the balance end is fixedly connected with the balance rod and is in loose-tight connection with the balance hinge piece through a bolt, the clamp is slidably sleeved on the balance hinge piece and is positioned outside the outer circle of the linkage mechanism seat, and the clamp and the outer circle surface of the linkage mechanism seat form a clamping surface under the state that the balance handle is loosened or screwed, so that the balance end can be locked and positioned or loosened when swinging up and down by 90 degrees, and the lamp end is linked and positioned.
8. A linkage mechanism of desk lamp as defined in claim 5, wherein the horizontal circular cutting plane of the linkage mechanism seat is a horizontal stop plane for balancing the swing of the hinge piece, said linkage mechanism is fixedly connected to said lamp holder with the supporting rod and placed on the plane, and the center of gravity of the desk lamp is located on said lamp holder with the supporting rod.
