Eye protection lamp and eye protection lamp luminosity adjusting method

Abstract

The invention discloses an eye protection lamp and an eye protection lamp luminosity adjusting method, belongs to the technical field of table lamps and provides the eye protection lamp which can effectively remove shadow and has cold and warm color temperatures as well as the eye protection lamp luminosity adjusting method. The lower end surface of a support is fixedly connected with the upper surface of a lamp holder, one end of a middle rod is hinged with the upper end of the support, one end of a connecting frame is hinged with the other end of the middle rod, one end of a rotating shaft is rotationally inserted into a groove formed in the other end of the connecting frame, the other end of the rotating shaft is fixedly connected with a lamp cap, two warm color LED lamp beads and two cold color LED lamp beads are mounted on the lamp cap, adjustment of the brightness of each warm color LED lamp bead and each cold color LED lamp bead is controlled by respective knob switches, four knob switches are all mounted on the lamp holder, and an outer cover glidingly sleeves the lamp cap. The eye protection lamp can avoid shadow and can be adjusted to proper color temperature and light ray intensity.

Description

technical field [0001] The invention belongs to the technical field of table lamps, in particular to an eye protection lamp. Background technique [0002] The principle of "eye protection lamp": ①Using frequency conversion electronic ballasts, the electrical frequency is increased 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 it. At the same time, the light uses three primary color phosphors to make the light soft and reduce eye fatigue. ②Adopt DC ballasts to convert AC power into DC power first, and use DC power to light the lamp, which also achieves basically no flicker, which can avoid visual fatigue and has no electromagnetic interference. [0003] During the use of the eye protection lamp, some shadows will be produced due to the effect of light, which will cause some inconvenience to the user. The color temperature of the eye protection lamp is a s...

Problems solved by technology

[0003] During the use of the eye protection lamp, some shadows will be produced due to the effect of light, which will cause some inconvenience to the user. The color temperature of the eye protection lamp is a single color temperature, which is universal, but it cannot be adjusted according to the specific situation of each person.
