Problems solved by technology

Third: LEDs have the problem of attenuation rate, and the replacement cost is high. What's more serious is that LEDs have high-energy blue light, which has strong penetration. Long-term use has great potential damage to the retina and macula of the human eye.
[0014] However, in the above-mentioned prior art, there are defects such as short luminous life, low luminous efficiency, and poor ultraviolet light filtering effect, and the coated titanium dioxide film is prone to cracks during the use of fluorescent lamps, which seriously affects the luminous effect.

Abstract

The invention provides a high light efficiency eye-protection lamp. A lamp tube of the eye-protection lamp is a fluorescent lamp glass tube; a transparent nanometer titania thin film is coated on an inner wall of the fluorescent lamp glass tube; and five rectifier diodes are adopted in a circuit of the eye-protection lamp. According to the high light efficiency eye-protection lamp provided by the invention, with the circuit design, the illumination is uniform without low-frequency flashing; and in addition, by adopting the fluorescent lamp tube coated with the nanometer titania thin film, the high light efficiency eye-protection lamp is long in service life, high in stability and high in color rendering property.

Description

technical field [0001] The invention belongs to a lighting fixture, in particular to an eye protection lamp for lighting, and more particularly to an eye protection lamp with high luminous efficiency. Background technique [0002] Eye protection lamps usually use variable frequency electronic ballasts to increase the electrical frequency from 50Hz to 30-50kHz, and the range of light brightness changes is very small due to the afterglow effect of phosphor powder, so the human eye basically does not feel stroboscopic. The light uses tri-color phosphors to make the light soft and reduce eye fatigue. In addition, the eye protection lamp adopts a DC ballast, which converts the AC power into a DC power first, and uses the DC power to light the lamp, which also achieves basically no flicker, can avoid visual fatigue, and has no electromagnetic interference. [0003] At present, most of the high-frequency eye protection lamps used in the market use high-frequency ballasts, which ha...
