Description

A kind of new LED Leaves'Shape energy-saving health read-write desk lamp

Technical field:

The utility model relates to a kind of desk lamp, relates in particular to a kind of power saving and can cooperate the brightness of external environment again and adjust self brightness, is 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:

Eyes can see that all things on earth is the catadioptric by light, things is experienced in projection, 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 Leaves'Shape energy-saving health read-write desk lamp of eye.

The purpose of this utility model is to realize like this, described a kind of new LED Leaves'Shape energy-saving health read-write desk lamp, comprise base, can send the Lighting Division and the illumination control circuit of illumination, its design feature be described base with Lighting Division between be connected by adjustable lamp neck, on base, be provided with power switch and time switch, Lighting Division comprises shell, light fixture plate and white led lamps, the light fixture plate is located in the shell, the light fixture plate is provided with white led lamps, face glass covers on the light fixture plate that has white led lamps and is fixed on the shell, 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 adjustment unit is connected with the led driver unit, and the led driver unit is connected with corresponding white led lamps.

The purpose of this utility model also can be achieved through the following technical solutions, described a kind of new LED Leaves'Shape energy-saving health read-write desk lamp, and its characteristics are for being provided with electronic clock on base.

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.Shell adopts Leaves'Shape, has elegant in appearancely, and the employing of adjustable lamp neck makes can regulate the desk lamp height.Being provided with of electronic clock can be satisfied the demand of user to clock.
