Description
Technical field
The utility model relates to desk lamp, is specifically related to the green eyeshield intelligent LED desk lamp of a kind of zero radiation no pollution.
Background technology
As energy-conserving light source of new generation, LED with its low cost, the life-span is long, colour temperature is optional and the advantage such as environmental protection and energy saving, is applied to illuminating lamp field more and more widely.Therefore the development of LED desk lamp is in recent years very rapid, and kind also emerges in an endless stream, and circulate LED eye protection table lamp miscellaneous on the market.And this wherein said eye-protecting function be the eyeshield pattern of one-side finger LED desk lamp without stroboscopic, but this is only from the one hand solving the eye fatigue of reading for a long time and causing, and less than itself leaving for from LED light source the light source seeking eyeshield.
At present LED desk lamp great majority be on the market the white light of the access expansion light adopted as best light source, and this wherein to endanger maximum to human eye be blue light, the injury of high energy shortwave blue light has surmounted common electromagnetic radiation and ultraviolet injury far away.LED light luminance is too large in addition, easily stimulates and hurts eyes, can not look at straight.The single Long-Time Service of light source colour of existing LED desk lamp can cause the sensation of reader's eye fatigue, ache, cannot play the effect of protection eyes.
In addition, in order to better advocate the theme of green low-carbon environment-friendly, the intelligentized desk lamp of LED is also entered into the market gradually.But, current desk lamp intelligence degree is not high, such as only employ the situation that infrared induction system does not consider ambient light photograph, also can be triggered in well-lighted situation or could not consider the intelligent requirements that desk lamp is closed, this technology abuse phenomenon seriously could not accomplish that people-oriented and play the effect of power saving and human-machine intelligence.
Utility model content
In view of the light source of current LED desk lamp cannot reach real eye-protecting function, reasonably realize the effect of intelligence simultaneously, the present invention proposes the green eyeshield intelligent LED desk lamp of the total zero radiation no pollution of Yi, using dark green light source as the light source under LED desk lamp reading model, fundamentally reach the eyeshield effect of light reading, green health; Intelligentized control method closed type switch, embodies the characteristic that people-oriented simultaneously.
The purpose of this utility model is to provide a kind of zero radiation no pollution green eyeshield intelligent LED desk lamp.
The green eyeshield intelligent LED desk lamp of zero radiation no pollution of the present utility model comprises: light source, closed type switch, dc source and current controling element; Wherein, light source comprises four small lamp bulbs, is respectively the small lamp bulb that red, green and blue three is colored, and the small lamp bulb that white; Four small lamp bulb close-packed arrays form spot light together, the light path road altogether of four small lamp bulbs; In parallel between three colored small lamp bulbs, on the branch road of the small lamp bulb of each colour, a current controling element of connecting; Three colored small lamp bulbs are in parallel with the small lamp bulb of white, are connected to dc source by main line; Main line arranges closed type switch.
In the utility model, the color of light source is dark green.In parallel between trichromatic three the colored small lamp bulbs of the blue B of the green G of red R, and a current controling element of connecting on respective branch road, in order to control the size flowing through the electric current of each fairy lamp pearl, thus control the brightness of each fairy lamp pearl; A white small lamp bulb in parallel again, by the brightness of method conservative control three fairy lamp pearls of hybrid modulation, thus is in harmonious proportion out the dark green being applicable to reading, reaches the object of vision protection fatigue-relieving.
Current controling element adopts resistance, or adopts pulse-width modulator, is used for controlling flowing through the electric current of three colored small lamp bulbs, to regulate the brightness of colored small lamp bulb.Current relationship between the small lamp bulb that red, green and blue three is colored meets: 7:80:11.
Four small lamp bulbs are respectively anistree LED lamp bead.Between three colored small lamp bulbs, close-packed arrays is together, forms triangle, then together with white small lamp bulb close-packed arrays; Four small lamp bulbs are encapsulated in the shell of a tubular; Because each small lamp bulb size is very little, is about 10mm, is approximately spot light after close-packed arrays, the light path of four small lamp bulbs is road altogether, is superimposed, and can be in harmonious proportion out different colors.
Further, the branch road of the small lamp bulb of white arranges by-pass cock, be used for regulating the brightness of white small lamp bulb.
The utility model comprises intelligent controlling device further, comprising: pyroelectric infrared sensor, signal processing circuit, photo resistance, single-chip microcomputer and light-controlled lamp unit; Wherein, pyroelectric infrared sensor is connected to single-chip microcomputer by signal processing circuit; Photo resistance is connected to single-chip microcomputer; Single-chip microcomputer is connected to light-controlled lamp unit; Light-controlled lamp unit is connected to the closed type switch be arranged on main line.
The utility model have employed pyroelectric infrared sensor and photo resistance simultaneously, be between the two " and " relation.Pyroelectric infrared sensor configuration signal processor is adopted to carry out amplification process to infrared induction signal, signal feedback after process is to single-chip microcomputer, single-chip microcomputer judges whether that needs are turned on light or turned off the light, then single-chip microcomputer sends instruction to light-controlled lamp unit, the disconnection or closed of light-controlled lamp unit controls closed type switch.
Intelligentized control method of the present utility model, comprises the following steps:
1) when LED desk lamp is in closure state, if ambient light degree of illuminating lower than photo resistance threshold value is set and human body enter can in pyroelectric infrared sensor induction range, now the triggering signal of pyroelectric infrared sensor and photo resistance imports single-chip microcomputer into simultaneously, single-chip microcomputer sends open command to light-controlled lamp unit, light-controlled lamp unit controls closed type switch closes, two triggering signals need exist simultaneously, indispensable;
2) when LED desk lamp is in running order, if ambient lighting brightness arranges threshold value higher than photo resistance or pyroelectric infrared sensor cannot sense signal, when at least there is one in above-mentioned two situations, single-chip microcomputer sends close command to light-controlled lamp unit, light-controlled lamp unit controls closed type switch disconnects, and LED desk lamp continuous firing 10 understands automatic distinguishing power supply after second.
Advantage of the present utility model:
(1) propose first to use dark green as the light source of LED desk lamp, utilize the LED lamp bead of RGB tri-look to be successfully in harmonious proportion out dark green eyeshield color light source by the method for hybrid modulation, effectively alleviate fatigue and the discomfort of reader's eyes;
(2) can regulate continuously light-source brightness, meet the demand of different reader for different brightness of illumination better;
(3) be configured with pyroelectric infrared sensor and photo resistance simultaneously, hommization devise intelligent functions, especially for the intelligentized design of turning off the light the better amount of saving energy, better echoed the design motif of green low-carbon environment-friendly.
