The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of LED Intelligent constant light desk lamp of more high-tech grade is provided.LED Intelligent constant light desk lamp design concept is: satisfying under the light source condition of certain optical index, take full advantage of natural daylight or surround lighting, the illumination of adjusting and integration station light, guarantee that the illumination of working face remains on constant value automatically.The application of this technology has realized that illumination of working plane is able to keeping on the lighting criteria value on the one hand, rather than fluctuation, thereby has satisfied to greatest extent the requirement of visual performance, vision safety and euphorosia, has reached the optimum efficiency of protection eyes; Owing to fully having effectively utilized natural daylight or surround lighting, save electric energy on the other hand, realized the purpose of green illumination.
Intelligent constant light technology can be formulated as: La ↑ ↓+Lb ↑ ↓ → Lm
(La is the desk lamp illuminance, and Lb is ambient light illumination, and Lm is for regulating the illumination of working plane after integrating) annotates: set third gear standard illumination (in 300Lx, 500Lx, 750Lx, error≤5%) on the scope of operation.
The purpose of this utility model is achieved through the following technical solutions: LED Intelligent constant light desk lamp, comprise LED luminosity scale, Desk lamp feet and the support bar that connects LED luminosity scale and Desk lamp feet, it is characterized in that, be provided with in described Desk lamp feet arrange standard illumination gear, respectively with the LED luminosity scale with standard illumination gear circuit be set be connected the dimming control system that is used for brightness adjusting, the photo resistance for detection of illumination on the scope of operation that is connected with the dimming control system circuit, the described standard illumination gear that arranges is 300Lx, 500Lx, three gears of 750Lx.
Be provided with the adjusting light circuit that the IC model is MCL01 in described dimming control system, described adjusting light circuit detects various optical wavelength and corresponding light intensity on the scope of operation according to photo resistance, automatically regulate the brightness of LED luminosity scale, make desk lamp scope of operation illumination automatically be adjusted to brightness value 300 Lx or 500 Lx or the 750Lx of setting, its error is in 5%.
Described photo resistance is arranged on the edge of Desk lamp feet, and described photo resistance detects the error of scope of operation illumination within 10%.
Described LED luminosity scale diameter is 19cm.
The length of described support bar is 46cm.
Described Desk lamp feet is oval, and its length is 21cm, and width is 19cm.
The scope of operation of described LED Intelligent constant light desk lamp irradiation is not less than 42cm x30 cm, and the uniformity of illuminance of this scope of operation meets Chinese lighting criteria.
The utility model can change according to ambient brightness does corresponding the variation; the automatic brightness adjustment of light; make illumination on the scope of operation remain in the scope of setting value (third gear: 300Lx, 500Lx, 750Lx respectively) (error is in 5%); therefore in people's reading and the activity such as write; both effectively protect eyes, saved again the energy.After surpassing when ambient brightness the illumination of setting, desk lamp can knock out automatically, and the utility model is simple and reasonable, manufactures easily, is of value to vision health, energy-saving and emission-reduction and low-carbon environment-friendly, has wide market prospects.
