Description

A kind of new LED small power energy-saving eye-protecting lamp

Technical field:

The utility model relates to a kind of desk lamp, relating in particular to a kind of power saving can cooperate the brightness of external environment again and adjust self brightness, neutralization thorn lasing light emitter or reinforcement faint light source are fit to the LED small power energy-saving eye-protecting desk lamp that eyes are looked the stabilized light source of thing so as to building.

Background technology:

The people is by the impression of eyes to light and heat, can clearly view and admire this well-rounded boundless universe, and this is constituted with very accurate tissue, nerve and blood vessel seeming in the small and exquisite organs of vision, and any one position all may sustain damage or catch, the infringement that causes eyes to remedy because neglect or do not treasure.

Eyes can see that all things on earth is the catadioptric by light, projection is experienced and is seen thing, the light wave of the Nature can be divided into visible light and black light two big classes, in visible light, the blue light energy of wavelength between 400～500nm is the highest, because science and technology now, blue light is full of in TV, computer, read desk lamp, public street lamp, partially electrical home appliances such as bluish violet indoor light and outdoor sunlight or lighting source in, point out according to up-to-date medical research, the high blue light of the short energy of wavelength can stimulate eyes, cause photophobia and eye fatigue, and if cellula visualis is long-time chronic exposure blue light, but the desk lamp of at present general work or reading usefulness, be as light source with osram lamp or mercury fluorescent tube, because osram lamp power consumption height, the mercury fluorescent tube glimmers easily, so all there is the shortcoming of economic benefit or eye health on using, and this class desk lamp generally can only manually be adjusted the brightness size of light source, and, because the brightness of desk lamp is the manually control according to user self sensation, when the user before being engaged in work or reading according to after the light source of desk lamp was adjusted in the brightness of external environment at that time, through work or reading after a while, the brightness of external environment is passed in time and is moved and variation to some extent, especially dusk at dusk or morning to the period at dawn, the difference of not experiencing overall brightness but the user may bury also that head majors in, so the fixing brightness of desk lamp may be seemed not enough because of external environment by bright deepening, perhaps bright and seem dazzling by blackout, exacerbate eye tired or cause the degeneration of awl cell virtually, add that the desk lamp itself that illumination is provided does not have the function of adjusting brightness with external environment automatically, can't provide suitable eyes to look the light source of thing.

Summary of the invention:

At the problem that above prior art exists, the purpose of this utility model provide a kind of energy-conservation, can regulate brightness, not hinder the New LED small power energy-saving eye-protecting lamp of eye.

The purpose of this utility model is to realize like this, described a kind of new LED small power energy-saving eye-protecting lamp, comprise the base of locating usefulness, can send the Lighting Division and the illumination control circuit of illumination, neck with a long handle shape between this base and this Lighting Division is connected, on base, be provided with power switch and time switch, Lighting Division comprises rear board, front panel and a plurality of white led lamps, front panel is provided with a plurality of white led lamps, front panel is installed on the rear board, the glass face shield covers on the front panel that has a plurality of white led lamps, its design feature is that described illumination control circuit comprises power module, the induction control module, led driver unit and single-chip microcomputer, the induction control module comprises the brightness impression unit, brightness adjustment unit and time switch unit, on the outside corresponding function pin of single-chip microcomputer, be connected with the brightness impression unit, brightness adjustment unit and time switch unit, the brightness impression unit is connected with the led driver unit, a plurality of white led lamps are connected with the corresponding LED actuator unit, and the time switch unit connects the time switch that base is provided with.

The beneficial effects of the utility model are: the utility model is owing to adopt white low-power LED lamp, do not have the function of adjusting brightness with external environment automatically by single-chip microcomputer and the induction of induction control module in the hope of improving existing desk lamp, cause the problem of eyes because of easy fatigue of uncomfortable light source or damage pathology.And used led driver unit adopts isolated constant current electric drive chip, and constant current electric drive chip adopts U.S.'s import constant current electric drive chip, have high and low power consumption of efficient and life-span long, energy-conservation, can regulate brightness, not hinder effect such as eye.
