Abstract
The invention discloses a method for generating a shadow pattern through light source illumination. A light source device capable of generating hemispheric light is arranged on the bottom face. Light emitted by the light source device on the bottom face is emitted to a target face through a shadow transmitting and scattering device to illuminate the target face, and therefore the shadow pattern is formed on the target face. The shadow transmitting and scattering device is of a surrounded structure so that the light emitted by the light source device can be converged, and the shadow transmitting and scattering device is provided with a plurality of transmitting structures and a plurality of scattering structures. The transmitting structures are used for generating the shadow pattern and the scattering structures are used for illuminating the whole target face. According to the method for generating the shadow pattern through light source illumination, the shadow pattern generated through projection of the shadow can be made to be clear, a boundary is clear, it can be guaranteed that the face generating the shadow pattern has the enough illumination degree, and a person feels that the light is soft and comfortable.
Description
Technical field
The present invention relates to lighting technical field, more specifically time, relate to a kind of method of light illumination generation shadow pattern.
Background technology
In social development today day by day fast, people are in meeting basic lighting demand, also pursuing aesthetic property, so, existing ligthing paraphernalia is a lot of by the simple illumination functions that provides, change to thering is aesthetic property and ornamental direction, become compound ligthing paraphernalia, existing light source throw light on time, the light that light source produces is in producing shadow pattern, its pattern is clear not, brightness is inadequate, and border is fuzzyyer, for produce patterned surfaces to illuminate degree inadequate.
Summary of the invention
The object of the invention is for the deficiencies in the prior art part, a kind of method that provides light illumination to produce shadow pattern, the shadow clear patterns of its generation, sharpness of border, illuminate degree to the face of generation shadow pattern high, makes people feel that light is soft, comfortable.

Detailed description of the invention
The following stated is only preferred embodiment of the present invention, not scope of the present invention is limited.
Embodiment, light illumination produces the method for shadow pattern, the light supply apparatus that can produce hemisphere face light is arranged on bottom surface, bottom surface can be the surface of installing plate or the surface of light source control module, and the light of light supply apparatus on bottom surface transmitting is illuminated and forms shadow pattern thereon through a shadow transmission and scattering device homed on its target face, target face can be ground, lawn surface or installed surface etc., the shadow transmission that described bottom surface is arranged on and center, scattering device one end, preferably, shadow is arranged on the upper end of shadow transmission and scattering device, like this, the light of described light supply apparatus transmitting is illuminated and is formed shadow pattern thereon through described shadow transmission and scattering device homed on its target face in mode from the top down, like this, and under the effect of gravity, light naturally droops, after light transmission, that collects is more concentrated, simultaneously, described shadow transmission and scattering device have encirclement type structure so that the light of light supply apparatus transmitting is converged, and described shadow transmission and scattering device have multiple transmittance structures and diffusing structure, the light that encirclement type structure can be sent light source collects, and prevents unnecessary scattering and disappearing, described transmittance structure is used to form shadow pattern, in the time that a part of light of light source passes transmittance structure, degree of collecting is higher, in target face, can form shadow pattern clearly, meanwhile, a part of light of light source is in projecting, after described diffusing structure scattering, disperse and come, can be used in and illuminate whole target face, described diffusing structure is positioned at described transmittance structure edge and described transmittance structure is surrounded, transmittance structure can be as required, set various shape, such as water-drop-shaped, rhombus, oval etc., the described diffusing structure formation enclosed construction that joins end to end, joining end to end here represents that diffusing structure does not have opening, and the shape that the shape of described enclosed construction and described transmittance structure form is corresponding, that is to say, the enclosed construction that diffusing structure forms is if circular, transmittance structure is also circular, and be surrounded by this enclosed construction, because diffusing structure transmittance structure is also enclosed structure, do not there is opening, transmittance structure is surrounded, so transmittance structure does not have opening yet.
Encirclement type structure is the seamless cylinder that is made of metal and has circumference side or multiple connected sides, that is to say, encirclement type structure can adopt seamless metal pipe or seamless metal section bar, the cross section of seamless cylinder is circle or regular polygon or rectangle or ellipse etc., metal can adopt carbon steel, aluminium section bar etc., diffusing structure and described transmittance structure are arranged on described seamless cylinder, why adopt metal material, because in thering is enough hardness and structural strength, there is enough durability degrees, can be after not using a period of time, there is change color, and adopt the mode of laser cutting by synchronous processing out, in general, transmittance structure and

and inside and outside diffusing structure does not all have difference in height in any point, such version is convenient to processing, also can produce reasonable transmission and dispersion effect, when the transmittance structure surrounding when inside and outside diffusing structure is circular, these continuous crossing lines surround circle, in the time that transmittance structure is regular polygon, inscattering structure and outer diffusing structure are exactly to be made up of line or the face equal with this regular polygon parameter, middle diffusing structure is also same reason, in addition, can also adopt, in the middle of described, diffusing structure is the clinoplain that described inscattering structure, outer diffusing structure are coupled together, and described clinoplain is outward-dipping extension simultaneously downwards, because light supply apparatus is positioned at the center of seamless cylinder, so when the light that it sends process transmittance structure and diffusing structure, tilt, just in time corresponding with clinoplain, described light supply apparatus comprises and sends the naked light source of scattered beam and send the secondary light-distribution light source that obtains collimated ray after light distribution device luminous intensity distribution, what naked light source adopted in the present embodiment is LED lamp pearl, and the employing of secondary light-distribution light source is, with the LED lamp pearl of reflector or reflection shield or lens or collimater, can also adopt the collimator apparatus of other work, the light of dispersing is collimated, in arranging, naked light source is positioned at center, because its light sending is dispersed relatively, and secondary light-distribution light source is arranged on naked light source around, general is that the mode that circularizes array centered by naked light source is arranged, further, secondary light-distribution light source is obliquely installed, secondary light-distribution light source is downward-sloping extension simultaneously outwards, and, the axis of secondary light-distribution light source and the axis of naked light source intersect at a point, and the axis of secondary light-distribution light source and the axis of naked light source acutangulate, and the scope of acute angle is between 30-45 °, the vertical setting of shadow transmission and scattering device on the ground, light supply apparatus end disposed thereon, so, the light that it sends, after penetrating
