Brief description of the drawings

Fig. 1 is the front elevational schematic that this reality strengthens LED illuminating lamp.

Detailed description of the invention

Below in conjunction with drawings and Examples, the present invention is further described:

In the embodiment shown in fig. 1, this reality strengthens LED illuminating lamp and comprises rectangle LED panel 1, described LED panel 1 is fixed with LED wafer array 2, and the each LED wafer in array is photochromic controlled light emitting diode, and controlled by common LED controller (not shown); Described LED panel 1 center is also provided with camera 3; Described camera 3 is coupled to arithmetic unit (not shown), and described arithmetic unit is coupled to described LED controller; Described arithmetic unit should send each described LED wafer photochromicly carries out computing, its method is as follows: first make each LED wafer all emit white light, absorb the ambient image (described illumination range and ambient image are all rectangular) in illumination range with this understanding by described camera 3; Then described ambient image is zoomed to the size identical with described LED wafer array 2, make described LED wafer array 2 be paved with described ambient image; Centered by position by each LED wafer in described ambient image, make a little square, make each little square zero lap and be paved with whole described ambient image; Calculate the occupied pixel of shades of colour in each little square, make to occupy the solid colour that pixel is maximum in the glow color of the corresponding LED wafer of this little square and this little square.

Above-mentioned reality strengthens LED illuminating lamp, and in the time calculating the occupied pixel of shades of colour in each described little square, first to color value equidistant partition interval, the color value falling within same interval is thought same color; Thereby large-area gradual change color lump can be thought to the main color in this little square, and prevent the little color lump of the small size constant color value in this large area gradual change color lump to be mistaken for this little foursquare main color. It is worth mentioning that, described interval is one dimension interval not necessarily, and because each coloured light all can be synthesized by three primary colours, therefore described interval can be between the space being made up of the numerical value of three primary colours, as red, blue, green color value all changes in 0 ~ 255 scope; Can make the siding-to-siding block length in each dimension (corresponding red, blue, green) between described space is 2, [0,2] * [0,2] * [0,2] be between a space, from geometric space angle, between a space corresponding to a small cubes, all colours is corresponding to the stacking large cube forming of a large amount of small cubes, and any color must drop in some small cubes; Just as interval [0,2] * [0,2] * [0,2], for color value (0,0,1), (0,1,0), (1,0,0), (0,1,1), (1,0,1), (1,1,0), (1,1,1), (0,0,2), (0,2,0) etc., 27(3*3*3 altogether) plant color, all drop in this interval, all think same color; Detail for the basic technology means of image processing field, repeats no more herein.

Above-mentioned reality strengthens LED illuminating lamp, and described LED wafer comprises red, blue, green Tricolor LED, and described LED controller is controlled the photochromic of this LED wafer by changing the current ratio of light emitting diode of all kinds.

Above-mentioned reality strengthens LED illuminating lamp, and described camera 3 can automatic focusing, and the ambient image of its picked-up adapts to the illumination range of described LED wafer array 2 automatically, makes the edge of ambient image and the edge of illumination range consistent; Implementation method is as follows: the periphery of described LED wafer array 2 arranges a circle infrarede emitting diode (not shown), in described camera 3, comprise infrared sensitization CCD, only having under the luminous situation of described infrarede emitting diode, regulate continuously the focal length of described camera 3, its visual field is increased from small to large continuously, reach peak strength until described infrared sensitization CCD senses the infrared light that described infrarede emitting diode sends; Because this circle infrarede emitting diode is corresponding to the edge of illumination range, now illustrate that the edge of ambient image and the edge of illumination range have reached consistent. In the case, photochromic more accurate for what in ambient image, each location point projected. It should be noted that, even if it is not accurate, the reality that also can obviously not affect this illuminating lamp strengthens effect, because coloured light itself is not pure, and body surface is impure for look reflection of light yet, when therefore coloured light is irradiated to body surface, will under diffuse reflection effect, produces and fill the air phenomenon, as long as while having near the each location point of body surface with the coloured light of this location point solid colour, the brightness of this location point just can be enhanced.

Above-mentioned reality strengthens LED illuminating lamp in the time of work, for each location point of the actual environment in its illumination zone, according to the actual color of this location point, give the illumination of same color, thereby make this location point reach maximum for the reflectivity of illumination, the utilization rate of luminous energy of throwing light on reaches maximum and embodies, and under less lighting power, can form to actual environment the illumination of stronger brightness; This has far-reaching using value for professional domains such as photographies.

The foregoing is only preferred embodiment of the present invention, in order to limit the present invention, within the spirit and principles in the present invention not all, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
