Novel reading eye-protection lamp

Abstract

The invention provides a novel reading eye-protection lamp, and relates to the technical field of LED illumination. The eye-protection lamp comprises an aluminum profile lamp holder, a bracket and a base, the aluminum profile lamp holder and the bracket are connected flexibly through a first connecting structure, the bracket and the base are connected flexibly through a second connecting structure, the first connecting structure comprises a first front and back steering connecting piece, a connecting base and a first up and down steering connecting piece, the first up and down steering connecting piece is arranged on the bottom end of the connecting base, the first front and back steering connecting piece is arranged on the upper end of the connecting base, the second connecting structurecomprises a second up and down steering connecting piece and a base bracket, and the second up and down steering connecting piece is arranged at the upper end of the base bracket. According to the novel reading eye-protection lamp, a special constant pressure scheme is adopted to output current point light source without stroboscopic, voltage fluctuation is controlled within 3%, thus the light fluctuation has no harm to a human eye, 12V / 5V low pressure input is adopted, and the eye-protection lamp can be used by connecting a power bank and is absolutely safe when the eye-protection lamp is used.

Description

technical field [0001] The invention relates to the technical field of LED lighting, in particular to a novel eye protection lamp for reading. Background technique [0002] Desk lamps are divided into two types: reading desk lamps and decorative desk lamps. Reading desk lamps are used as auxiliary supplementary lighting for reading and writing, and should play a role in increasing the illumination of key areas of work. After many years of development, the current mainstream reading desk lamps use energy-saving lamps and LED light sources as the main light source. Common desk lamp products on the market have the following problems: [0003] 1. Stroboscopic hazard: When the light source is lit, it is not a continuous and stable brightness, but a periodic on-off-on-off, or periodic light fluctuations as the power supply current fluctuates, and the eyes must also adjust the pupil size accordingly , so the ciliary muscle is easily fatigued. The ballasts for energy-saving lamps ...

AI Technical Summary

Problems solved by technology

[0003] 1. Stroboscopic hazard: When the light source is lit, it is not a continuous and stable brightness, but a periodic on-off-on-off, or periodic light fluctuations as the power supply current fluctuates, and the eyes must also adjust the pupil size accordingly , so the ciliary muscle is easily fatigued

The ballasts for energy-saving lamps are generally magnetic ballasts and high-frequency electronic ballasts. The frequency of magnetic ballasts is 100HZ, and there are obvious strobes. The frequency of high-frequency electronic ballasts is 20KHZ, which is almost felt by the human eye. Less than stroboscopic, but because the reading desk lamp is very close to the human body, the electromagnetic oscillation of the high-frequency electronic ballast will have a great impact on the brain

LED generally adopts constant voltage power supply or constant current power supply, and ordinary power supply has current fluctuations with the input AC power, resulting in light fluctuations in LEDs

[0004] 2. Blue light harm: Blue light mainly causes irreparable damage to the retina, and blue light with a wavelength of 440nm is the most harmful. At present, the principle of light emission of white light LED light sources is that the blue light LED chip passes through the yellow phosphor to form white light, and the positive white light without treatment LED light source blue light all exceed the standard

[0005] 3. Other light hazards: both infrared and ultraviolet light can easily cause cataracts

[0006] 4. Glare hazard: Glare refers to the strong contrast between light and dark in the viewing environment, which will cause temporary partial blindness to the eyes and damage the retina. Reading and writing under the glare lighting environment for a long time will cause ametropia, visual dysfunction, Biological clock disorder, induced mental illness
