Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is described in further detail.Following examples for illustration of the utility model, but are not used to limit scope of the present utility model.
As shown in Figure 1, the utility model embodiment provides a kind of multiple light courcess working light, comprising:
Be hinged to the first lampshade 3 of rotating shaft 6 and the second lampshade 5, first lampshade 3 and/or the second lampshade 5 all can 6 rotate and make formed variable angle around the shaft; The inner side of the first lampshade 3 and/or the second lampshade 5 is provided with king light 9, and side is provided with side lamp, and from Fig. 1 and Fig. 3, side lamp comprises near the interior side lamp 41 of rotating shaft 6 and the outer side lamp 42 away from rotating shaft 6.
Control unit (not shown), for controlling the brightness of angle and/or king light 9 formed by the first lampshade 3 and the second lampshade 5.Control unit is such as rotated by Motor Control rotating shaft 6, and rotating shaft 6 drives one of them lampshade or two lampshades to rotate.
In this embodiment, by two-piece type king light and the design of band side lamp, and two king light angles can change, thus illumination is more even, also be convenient to regulating illumination area, and be provided with control unit, thus conveniently can regulate range of exposures and the irradiation brightness of working light.
King light 9 can be any suitable light source, such as, be the light source without stroboscopic such as DC fluorescent lamp tube, LED, OLED, preferably adopts OLED area source, this is because OLED area source can cut, frivolous, soft, blue light harm is little.The surface of king light 9 can also arrange diffuser plate, improves further and irradiates uniformity.First lampshade 3 and the second lampshade 5 can be made up of light-transmitting materials.
As shown in Figure 1, the preferred support of the present embodiment 2 is Height Adjustable jack column, and one end of support 2 is connected to rotating shaft 6, and the other end is connected to base 1.Support 2 not only highly can regulate, and can on base gyrobearing.
The surface of base 1 such as can cover the acrylic layer of high transmission rate.Base 1 is provided with the infrared camera 10 as eye recognition device, and it can identify human eye, when working light is connected with the mains, just enters standby mode, only senses that the existence of human eye just can be luminous at infrared camera 10.As shown in Figure 1, for the ease of observing human eye, the upper surface of base 1 becomes an angle of inclination with bottom surface.Certainly, in the utility model, also can not adopt infrared camera and adopt other can realize the device of eye recognition.If be placed on lampshade by infrared camera 10, but in general lampshade should to obtain larger illumination zone on human eye, higher than the number of people.When user is sitting in before desk, lampshade is higher, inductor will respond to the number of people may need the micro-new line of user to coordinate, if now desk lamp light source is opening, people lifts eye and is just easily subject to light source direct projection, is harmful to eyes, and is placed on base and does not just need user deliberately to come back, also human eye can not be made to stimulate by high light, and this is a kind of more humane design.
Infrared camera 10 can also determine frequency of wink, makes described light intensity reduce when frequency of wink exceedes predeterminated frequency.Principle is, infrared camera 10 can record twitching of the eyelid action, and thus control unit can calculate frequency of wink, and frequency of wink excessive explanation people is very tired.Control unit can regulate the light intensity of king light 9 to diminish gradually accordingly when frequency of wink exceedes predeterminated frequency, and will recover normal light intensity again when being less than predeterminated frequency.Generally speaking, people, just within conventional at the moment one minute, blinking about 25 times, at about 15 times during reading, therefore such as can be set as predeterminated frequency to blink about 30 times for one minute.
Certainly, when can't detect human eye information in a period of time, control unit can also close king light and side lamp, with economize energy.
In addition, infrared camera 10 can also determine the distance of human eye and multiple light courcess working light following table.As shown in Figure 2, when user is in normal sitting position, the infrared camera of base catches position of human eye information, by the air line distance L of human eye and camera, the angle α of sight line and camera place plane calculates the vertical height of the number of people and horizontal table top, due to infrared camera distance height of table top h and and desktop angle β be fixed value, the height that therefore can calculate human eye distance desktop is H=Lsin (alpha-beta)+h, and then altitude information is transferred to control unit, it is (not shown to motonsed actuating units that control unit sends instruction, such as with motor), and then regulate the height of telescoping shoring column 2, until the height of support 2 reaches the setting height of mating with height H.Setting height corresponding to each height H scope can set by experiment.Generally speaking.Setting support height is limited within the scope of 40-70cm and regulates.When detecting that eyes of user distance vertical is apart from less than 30cm, does not perform lower step command.Certainly, when height H is less than a preset height, can assistant voice remind or indicator lamp flicker instruct user's correcting sitting postures.
In order to Intelligent adjustment range of exposures and luminosity, the utility model is also provided with the first optical inductor 7, as shown in Figure 1, be arranged in rotating shaft 6, for measuring the ambient light intensity above rotating shaft 6, control unit controls the brightness of angle and/or king light 9 formed by the first lampshade 3 and the second lampshade 5 according to the ambient light intensity recorded.Concrete example as: when ambient light intensity is greater than threshold value (being generally 100-200lx), control unit controls angle formed by the first lampshade 2 and the second lampshade 5 between 120 ° and 180 °.In the present embodiment, environmentally brightness automatically regulates angle within the scope of 120 °-180 °, and surround lighting is stronger, and angle is less, and plane of illumination reduces, and all right appropriateness reduces the light intensity of king light 9 of course simultaneously, avoids the environment too become clear to cause stimulation to human eye.When general environment light is stablized, illumination is up to standard, it is better that angle is stabilized in anti-dazzle performance between 150 ° and 180 °.When ambient light intensity being detected lower than threshold value, enter Night, the first lampshade 3 and the second lampshade 5 superimposed, and the king light 9 of the first lampshade 3 and the second lampshade 5 all outwardly, namely such as by the back side of the second lampshade 5 automatic turning to the first lampshade 3, angle becomes 360 °, as shown in Figure 3.Now can also reduce the king light brightness of the second lampshade 5, improve the brightness of the king light 9 of the first lampshade 3.Like this, both provided and penetrated light, and side lamp all can have been opened again, thus improved periphery and top ambient brightness, ensure that user can at the high environment work of an illumination uniformity, sight line is mobile everywhere all can not produce sense of discomfort.
In addition, when described ambient light intensity is less than threshold value, when angle becomes 360 °, control unit is also for controlling interior side lamp 41 and outer side lamp 42 is opened; When ambient light intensity is greater than threshold value, when angle is between 150 deg. and 180 deg., control unit also for controlling, open, interior side lamp 41 is closed by outer side lamp 42.Like this, light can be uniformly distributed and not waste in both modes.
The multiple light courcess working light of the present embodiment, the second optical inductor 8 can also be comprised, be arranged on the first lampshade 3 or the suitable position of the second lampshade 5, measure illumination for receiving light that table top object reflects, control unit also makes illumination reach predetermined luminous intensity for regulating the light intensity of king light according to illumination.What the light adjusting system of prior art controlled is light intensity is not illumination, illumination and light intensity proportional, and light source is inverse ratio to desktop square distance.Second smooth optical inductor 8 is placed on lampshade forward position, and sensitive surface is downward, accepts the reflection ray of desktop or books, thus measures illumination.Wherein, so-called illumination is intensity of illumination, to refer generally in unit are accept the energy of visible ray, unit lux (Lux or Lx).Illumination (illumination/illuminance) on a surface irradiated by light is defined as the luminous flux be radiated in unit are.If the luminous flux on bin dS is d Φ, then the illumination E on this bin is: E=d Φ/dS.Illumination might not equal reflective light intensity, but under working light environment, human eye is actual, and what receive is the intensity of illumination of reflection ray, so test receives the intensity of illumination of the light that table top object reflects and carries out measuring and have more simple, actual meaning, therefore here in this, as the index of instruction illumination.The impact of light source itself and environment is taken into account by such design in the lump, reflects the true illumination that user receives, and does not need to consider surround lighting and light fixture itself respectively.If optical inductor 2 is placed on base, then do not consider scope of operation reflectance factor, when the reflectivity of operation plane materiel material is too high, easily cause reflected glare.Generally speaking, xanthous pupil color is comparatively dark, and pupil is less, and the illumination that read-write operation needs is higher than occidentals, and desktop-centric surround 500-600lx is best.
It should be understood that, in the utility model embodiment, control unit can comprise various hardware and software, hardware is CPU, PLC, single-chip microcomputer, memory device, switching device, logic circuit etc. such as, and the utility model is not construed as limiting this.Control unit can be integrated unit, also can comprise each separate unit.Can there is signal contact with control unit in other devices, both also can complete independent of control unit via control unit during other device practical functions.Control unit can be arranged in base 1, to reduce the thickness of lampshade, certainly, is arranged on other positions is also fine as long as can realize controlling functions.
Above embodiment is only for illustration of the utility model; and be not limitation of the utility model; the those of ordinary skill of relevant technical field; when not departing from spirit and scope of the present utility model; can also make a variety of changes and modification; therefore all equivalent technical schemes also belong to category of the present utility model, and scope of patent protection of the present utility model should be defined by the claims.
