Description

Integrated three-dimensional light distribution device

Technical Field

The invention relates to an integrated three-dimensional light distribution device, in particular to a light distribution device.

Background

The light is the soul of photography. During the working process, the photographer often needs to adjust the color, intensity and angle of the light according to different photographing purposes.

The light distribution mode is variable and difficult to learn. The earliest light distribution technique originated from painter Lunebelan, and formed a triangular light spot on the front face of a person, clearly and powerfully showing the bone structure and nose shape of the face. Under the condition of only one lamp, the light is used for darkening the periphery to brighten the main body, so that a sharp light and shade boundary is brought, and the stereoscopic impression of people is highlighted. Specifically, a main light source is used to illuminate the face, and one side of the main light source is provided to illuminate two thirds of the face, namely, the light is positioned on one side of the face and higher than the face.

However, this glazing has its drawbacks. Most of the face of the model is in shadow, the stereoscopic impression is strong, five sense organs are strongly highlighted and emphasized, the shooting is suitable for correcting the face shape, but the defects of the model can be enlarged instead. For example, when the eyebrow is too high, the eye sockets are shadowed, or the eye bags and cheeks are loose, and when the light source is turned from above, the shadows are noticeable. In this case, the condition can be balanced by adding a soft light which is arranged from bottom to top, and the condition is called 'apple light'. When the light source is from bottom to top, the face looks like shining, the face has a soft focus effect, and pores, fine lines, darkness and other problems on the face are simultaneously modified.

In order to pursue "full, flawless, light-feeling", in the actual photography, four lights or five lights may be used for lighting, such as main light, auxiliary light, ceiling light and background light. Besides the slightly inclined main lamp, the auxiliary lamp with soft light at the lower part is used for balancing pores and fine lines of the human face, and the eyes are brighter and more transparent. The top light is used for highlighting the texture of hair, and the background light is used for eliminating the shadow of the main light and the auxiliary light, so that the background is naturally gradually changed, and the layering sense is increased. The background light can be removed, the background light is changed into a remote double light, all the things are illuminated in parallel, and the model looks transparent and soft.

Statistically, in basic portrait photography, there are up to 24 lighting techniques with single and double lights, and the light control fittings used are very diversified, such as soft light boxes, reflectors, white soft light umbrellas, beam masks, etc. In specific use, a photographer selects different light control accessories according to the specific situation of the model, and the light is distributed in the following mode:

first, the photographer adjusts the position of each light. For example, some people with too high cheekbones are not suitable for stronger contrast; some people have flat five sense organs and can look stereoscopic by enhancing contrast; some people have narrow faces and need to be put on the side of a high position to form a light and a contour.

Secondly, besides adjusting the position of each lamp, the photographer also needs to adjust the brightness of the lamp light according to specific conditions. The brightness required is also different in windows with good lighting and in shaded rooms, in sunny morning and on rainy days.

Further, in addition to adjusting the position and intensity of each light, the photographer also adjusts the color of the light to give the photograph different mood and atmosphere. For example, cold light sources look more serious, bitter, and even shady, while warm light sources may appear warm or even hot.

However, in real life, even if the complete studio of the photographic equipment, huge device is inconvenient to move, the color temperature of the bulb is not adjustable, and the photographer is required to adjust according to local conditions during photographing, such as the angle of the main light, the intensity and the angle of the auxiliary light, the proportion of the main light and the auxiliary light, and whether the top light is required, and the photographer needs to start the brains and try repeatedly. Sometimes photographers need to resort to small skills such as holding a reflective panel against a window or a model. Common photographers do not have professional photographic equipment or professional photography skills, and the shooting effect is naturally more discounted.

Therefore, it is very important to provide a stereoscopic light distribution device that can obtain the best possible light source under a limited budget, is adjustable, and is also convenient to adjust.

Disclosure of Invention

The invention aims to solve the technical problem of providing an integrated three-dimensional light distribution device which is low in cost and capable of distributing light in multiple angles. Therefore, the invention adopts the following technical scheme:

the light distribution device comprises a plurality of light sources which are encircled, and the light emitted by the light sources is not completely parallel to each other.

Due to the adoption of the technical scheme, the invention provides the multi-angle light source, and creates the light distribution effect similar to multi-angle light distribution of a photostudio.

When the integrated light distribution device provided by the invention is used for shooting, the cost of the shooting device can be saved, the professional threshold is reduced, the success probability of shooting is maximized, and a non-professional photographer can obtain a better shooting effect.

The invention can also adopt the following further technical scheme:

further, the plurality of light sources enclosing the ring are connected with each other;

furthermore, the angles between the light emitted by the light source and the plane where the circles formed by the light source are arranged are respectively adjustable;

furthermore, a shooting device position is arranged among the plurality of light sources which are encircled;

furthermore, a mirror is arranged among the plurality of light sources which are encircled;

furthermore, a background lamp is arranged among the plurality of light sources which are enclosed into a ring;

further, the light source is a monomer with adjustable brightness;

further, the light source is a monomer with adjustable color temperature;

further, the stereoscopic light distribution device further comprises a brightness editing chip of the plurality of light sources;

further, the stereoscopic light distribution device further comprises a color temperature editing chip of the plurality of light sources.

The invention adopts completely opposite ideas to solve the problem that a photographer often selects light sources with movable positions or angles to conveniently distribute light from different angles, and the photographer only needs to adjust the light sources at the required angles by enclosing a plurality of light sources into a circle and presetting the light sources, wherein each light source can independently adjust the brightness and the color temperature.

Through the technical scheme, a photographer can select the light source at each angle according to specific conditions and specifically adjust the light source according to needs, so that the cost and the energy of the photographer are saved, and a good shooting effect can be obtained when ordinary people take pictures by themselves. When the face-lighting lamp is used, the face generates soft light and shade change through the plurality of light sources with different angles and adjustable brightness and color temperature, and the face has more volume and is more beautiful.

The invention is also particularly suitable for the taking of identification photographs. The basic requirement of taking the identification photo as the most basic and widely applied portrait photography lies in really showing the appearance of a shot person, while the most beautiful identification photo popular in the market at present often has the defects that the face shadow is not three-dimensional enough, and the excessive trimming at the later stage is very different from the original person. The invention can be combined with the existing certificate photo self-service shooting device, so that the shooting effect is beautiful and real.

Detailed Description

Example 1

Referring to fig. 1 and 2, which include a plurality of light sources 2 that are looped, the light emitted by the light sources 2 is not perfectly parallel to each other.

The embodiment also comprises a mirror 1 in between the plurality of light sources 2 enclosing a ring.

As shown, in this embodiment, the plurality of light sources 2 enclosed in a ring are interconnected by an intermediate mirror 1. Specifically, the plurality of light sources 2 are connected to the mirror in the middle, and all the light sources 2 are connected to one another through the mirror in the middle to be used as a single cosmetic mirror.

In the present embodiment, the angles between the light emitted from the light source 2 and the plane where the circles formed by the light source 2 are arranged can be adjusted respectively. Specifically, in the present embodiment, the plane of the circle formed by the light sources 2 is actually the plane of the mirror 1 in the middle, and the irradiation angle of each light source 2 can be adjusted by rotating each light source 2, so that the angle between each light source 2 and the plane of the mirror 1 can be adjusted respectively.

Further, each of the light sources 2 is a single body with adjustable brightness.

The embodiment is provided with a circle of light source with adjustable angle and adjustable brightness, and the optimal illumination angle is adjusted according to the depth of the outline of the face of a person, so that the face in the cosmetic mirror is bright and soft, and fine skin color and tone are displayed.

It should be noted that the mirror 1 in the present embodiment may be replaced by a backlight, and used as a professional lighting device.

Further, in the present embodiment, the light source 2 is a single body with adjustable color temperature.

The color temperature of light is important in making up. In the using process of the embodiment, a user can avoid deviation of skin color by combining the cold light source and the hot light source. For example, a warm lamp with a color temperature of about 3200K is selected from the left and the right, a cold lamp with a color temperature of about 5600K is selected from the top, and the face color is prevented from being too yellow or too white through cold and warm mixing.

Further, the stereoscopic light distribution device of the present invention may further include a brightness editing chip of the plurality of light sources 2.

Further, the stereoscopic light distribution device of the present invention may further include a color temperature editing chip of the plurality of light sources 2.

The brightness editing chip and the color temperature editing chip can be combined into one or can be separately arranged.

In general, the present embodiment can edit the color temperature and the brightness of a single light source by using the total brightness editing chip and the color temperature editing chip.

If in order to save cost, the color temperature and brightness of the light source at each position can be preset directly for different sale environments without presetting the chip, or different light transmitting sheets for replacement are prepared for adjusting brightness, so that the use difficulty of a user is reduced.

Example 2

Referring to fig. 3 and 4, the present embodiment comprises a plurality of light sources 2 enclosing a circle, the light emitted by the light sources 2 not being completely parallel to each other.

This embodiment 2 replaces the mirror in the middle of embodiment 1 with the camera station 4. As shown in the figure, in the present embodiment, the plurality of light sources 2 enclosing a circle are connected to each other as a whole, and the camera is located in the middle of the light sources 2 enclosing a circle. When the device is used, a camera or a mobile phone can be placed on the camera position 4 for shooting, and the shooting effect is improved through the assistance of the embodiment.

In the present embodiment, the angles between the light emitted from the light source 2 and the plane where the circles formed by the light source 2 are arranged can be adjusted respectively. The illumination angle of each light source 2 can be adjusted by rotating it.

Each light source 2 is a single body whose brightness and color temperature are adjustable, or a single body which is replaceable with a light transmitting sheet, similarly to example 1.

It is a reason for each light source to be able to adjust the illumination angle and to adjust the brightness separately.

From the light distribution perspective, the studio often adopts even and soft multi-angle professional light distribution, which is divided into front light, overhead light, side light, backlight and the like. Photographers also have special skills such as holding the light head up to avoid shadows caused by flash lights, and using the light reflected from the ceiling to make the light more soft on the face of the person.

In terms of the brightness of the lighting, different environments require different brightness, such as a bright window side and a dark room, and the required brightness is different in a bright sunny day and a dim cloudy day.

In this embodiment, the brightness editing chip and the color temperature editing chip are integrated, and color temperature and brightness editing can be performed on a single light source through the total brightness editing chip and the color temperature editing chip.

When the LED lamp is used specifically, the angle, the color temperature and the brightness under different situations can be preset in the chip for a user to select, the use difficulty of the user is reduced, and the use effect is improved.

In this embodiment, a ring of light sources 2 formed by splicing together form a ring shape. In this embodiment, the inner side of the ring shape is an arc surface, and the human face is irradiated by the cage. This makes the embodiment use, and the shooting effect of plane light source such as ordinary beauty lamp is great different. Specifically, there are four differences:

first, a change in the irradiation angle is brought about.

In the photography studio, because the photography light source is far away, the main light is almost parallel light, and the light and shade change is obvious during irradiation, soft light supplement needs to be carried out on the side surface, which is not only the reason of a light supplement box or a light supplement plate for the photography studio, but also the reason that the photography studio can take a better effect. The invention is used for close-range shooting, the effect of front, vertex and side light distribution is simulated by multi-angle irradiation in the arc surface range as small as possible, the face is huge and more three-dimensional, the eyes of a shooting object can be opened due to the soft and bright light, the soft shadow can not cover the facial expression, wrinkles and scars can be weakened, fine skin color and tone can be displayed, the satisfaction degree of a user is improved, and the distortion sense of the beauty of software can not be caused.

Secondly, each light source 2 can edit the brightness separately, bringing about brightness variations at different angles.

Each light source 2 of the present embodiment may be set to a brightness separately to meet the light use requirements in different directions. Editing light combination modes according to different face contour characteristics, for example, a highlight direction light box needs more direct lighting; the dark part direction lamp box meets the requirement of floodlight. The face is shaped to be more three-dimensional and more layered by using the lamplight.

Each light source 2 has a brightness variation, which means that the illumination around the face is different. The invention enables the face to generate soft light and shade change through multi-angle light distribution and brightness change, and the face has more volume and beauty.

Third, each light source 2 can also adjust the color temperature separately. The illumination and color temperature editing chips of the light sources at different angles are customized LED chips, and optical coefficients of different skin colors can be preset, for example, color rendering of an R9 area is improved for a yellow race person, so that the skin color of a photo is more ruddy and healthy.

Fourth, this embodiment ensures high light in the eyes of each portrait photograph.

Whether the eyes of the person catch the mind of determining whether the portrait photo succeeds or not. The embodiment fixes the relative positions of the human face, the light part and the camera shooting part, so that highlight, brightness and permeability in eyes of each portrait photo can be guaranteed, and everyone looks spiritual.

In summary, when the present embodiment is used, the present embodiment can be used as an auxiliary light distribution device for photography, which helps to obtain a better shooting effect.

Example 3

Example 3 is similar to example 1 except that the mirror 1 in this example is rectangular.

It should be noted that the "circle" in the present invention is a circle arranged around one light source of the mirror, and is a circle in the embodiment 1, and is a rectangular circle in the embodiment. In practice, it may be a square ring, a polygonal ring, or even a multi-layer ring, for example, three layers of rings which are gradually reduced, so as to form a three-dimensional hemisphere. The purpose of the circle formation is to provide a plurality of light sources with different angles, such as a top angle light source, a side left-right angle light source and a bottom angle light source, and the circle formation has the effect of covering the face like photographic cloth light.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention.
