Abstract
The invention discloses an indoor sunlight-imitated LED (light emitting diode) illuminator, which comprises an outdoor sunlight color temperature collecting module, a main control module, a transmission module and a color-temperature-adjustable lamp, wherein the outdoor sunlight color temperature collecting module is connected with the transmission module, the transmission module is connected with the main control module, and the main control module is connected with the color-temperature-adjustable lamp. The outdoor sunlight color temperature collecting module transmits collected data to the main control module through the transmission module, and then, the main control module outputs corresponding color temperature data to the color-temperature-adjustable lam according to the input RGB (red green blue) data requirements for carrying out lamp light color temperature regulation. The indoor sunlight-imitated LED illuminator has the advantages that the illumination lamp light color temperature is adjustable, so the indoor illumination can completely reach or approach to the illumination effect of outdoor natural light.
Description
Technical field
The present invention relates to a kind of LED lighting device, relate in particular to a kind of indoor imitative sunshine LED lighting device, belong to technical field of lighting fixtures.
Background technology
At present indoor illumination, such as indoor places such as office, office building, market, hospital, school, families, generally take positive white light or cold white-light illuminating as main, only has a small amount of and Code in Hazardous Special Locations as bedroom, coffee shop, and dining rooms etc. just can be used warm white illumination.Traditional lighting source, as Non-polarized lamp, high-pressure mercury lamp, incandescent lamp, electricity-saving lamp, straight tube fluorescent lamp etc., do not there is the adjustable function of colour temperature, therefore, after the lighting installation of prior art, the effect of room lighting is just fixed up, and the colour temperature of light can not change, illuminating effect is more single.
Known by studying and test the sunshine of occurring in nature, the variation along with the time in the middle of a day of the colour temperature of sunshine changes.The colour temperature of morning and sunshine is at dusk lower, and greatly about 3000-4000K left and right, and noon is higher, more than 5500K.The colour temperature of Various Seasonal synchronization sunshine is different again.While, the colour temperature of sunshine was also inconsistent along with latitude increases.According to current solar light collection technology, can gather out chromaticity coordinates and the color temperature value of the sunshine of different time sections completely, and send these data to memory device, preserve with the form of database.According to CIE1931 chromatic diagram, redgreenblue light can mixed light becomes to approach the white light of any one colour temperature section in CIE1931 blackbody curve.Therefore by analyzing the spectrum of sunshine, according to existing LED light source technology, RGB (RGB) three coloured light combinations can be carried out to mixed light, obtain lighting and send the white light close with sunshine, and colour temperature along with the time or specific program adjustable.
Summary of the invention
The object of the present invention is to provide a kind of indoor imitative sunshine LED lighting device, the houselights colour temperature of this device is adjustable, makes room lighting can reach or approach the illuminating effect of outdoor natural daylight completely.
A kind of indoor imitative sunshine LED lighting device, comprises outdoor sunshine colour temperature acquisition module 1, main control module 2, transport module 3, adjustable color temperature light fixture 4.Described outdoor sunshine colour temperature acquisition module 1 is connected with transport module 3, and described transport module 3 is connected with main control module 2, and main control module 2 is connected with adjustable color temperature light fixture 4.Described outdoor sunshine colour temperature acquisition module 1 sends the data of collection to main control module 2 by transport module 3, then exports corresponding colour temperature data to adjustable color temperature light fixture 4 by main control module 2 according to the RGB data demand of input, carries out the adjusting of light colour temperature.
Object of the present invention can also further realize by following technical measures:
Imitative sunshine LED lighting device in aforementioned compartment, wherein outdoor sunshine colour temperature acquisition module 1 is made up of three photodiodes, and three photodiodes hide with red, green, blue optical filter respectively.
Compared with prior art, the invention has the beneficial effects as follows: houselights colour temperature is adjustable, make room lighting can reach or approach the illuminating effect of outdoor natural daylight completely.
Accompanying drawing explanation
Fig. 1 is circuit structure diagram of the present invention.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the invention will be further described.
As shown in Figure 1, indoor imitative sunshine LED lighting device comprises outdoor sunshine colour temperature acquisition module 1, main control module 2, transport module 3, adjustable color temperature light fixture 4.Described outdoor sunshine colour temperature acquisition module 1 is connected with transport module 3, and described transport module 3 is connected with main control module 2, and main control module 2 is connected with adjustable color temperature light fixture 4.Described outdoor sunshine colour temperature acquisition module 1 sends the data of collection to main control module 2 by transport module 3, then exports corresponding colour temperature data to adjustable color temperature light fixture 4 by main control module 2 according to the RGB data demand of input, carries out the adjusting of light colour temperature.Adjustable color temperature light fixture 4 be a kind of self with driving and communication interface standard, and be the light fixture of mixed light.Communication interface is considered lamp installation aloft, realizes with remote control.
Aforementioned sunshine colour temperature harvester is made up of three photodiodes, and three photodiodes hide with red, green, blue optical filter respectively, read in real time R, G, B numerical value; Adopt binary system, byte 8 bit representations.Can store, 16 systems are read, for example R:F8; G:D3; B:B8.Sunshine colour temperature harvester also, with the transmitting tube of a remote control output, is issued light fixture data.
The brightness ratio that the present invention adopts R, G, B tri-color chips to be encapsulated in 5050, three chips in a support is that R:G:B=39:50:11 reaches white balance.Each brightness is divided into i.e. 256 grades of FF.Therefore lighting can send you want need light.Different colour temperatures, different colors, follow one's bent.Indoor illuminating effect can be follow one's bent be change.Than existing illumination, colour temperature is single non-adjustable, and illuminating effect is stiff, and light colour temperature of the present invention is adjustable, can follow one's bent completely.The present invention compared with prior art has the following advantages:
1) outdoor sunshine colour temperature acquisition module gathers the colour temperature data of sunshine accurately, and sends these data to main control module, for it provides accurate colour temperature data.
2) main control module has man machine operation interface, and device can manually arrange, or user can measure the light remote control lamp under good natural environment and obtain corresponding illumination light.
3) the houselights colour temperature of adjustable color temperature light fixture is adjustable, makes room lighting can reach or approach the illuminating effect of outdoor natural daylight completely.And be no longer single color temperature lamp optical illumination.
4) can be used on the place that special occasions needs light effects.
In addition to the implementation, the present invention can also have other embodiments, and all employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection domain of requirement of the present invention.
