Detailed description of the invention
Structure to the high-power LED strip-light lamp based on penalty method is specifically addressed, taking the horizontal line by high-power LED light source array geometry center as X-axis, taking by high-power LED light source array geometry center, perpendicular to the straight line of X-axis as Y-axis, to set up coordinate system by high-power LED light source array geometry center and perpendicular to the straight line of X, Y-axis as Z axis, the corresponding high-power LED light source of Z axis is to the distance of showing up.
A structural representation for high-power LED strip-light lamp based on penalty method as shown in Figure 1, comprises high-power LED light source 1, reflecting plate 2, base plate 3 and left and right sides reflecting curtain 4,5. The high-power LED light source 1 of arranging for horizontal linearity in the present embodiment is by 5 power 30W, and the LED light source that is of a size of 35mm*35mm is arranged along X-axis equidistant linear array row, and each LED drift angle is in the horizontal direction 10 °, and the optical axis of LED light source upward; The inner surface of reflecting plate 2 is Extrude Face, is stretched and forms along the linearly aligned direction of LED light source by stretching bus, forms free form surface reflecting surface, and reflecting surface has curvature at lamp on the direction of showing up. On bus, the curvature of each point calculates according to optical extend law of conservation and reflection law, and in figure, reflecting plate 2 is 200mm at the width of directions X, and the height of Y-direction is 215mm, and reflecting plate 2 inner sides are coated with reflectance coating; Base plate 3 can be set arbitrarily according to the attractive in appearance, practical etc. of light fixture, and the light that high-power LED light source 1 is sent does not produce effect, does not affect the uniformity of showing up; Left and right sides reflecting curtain 4, perpendicular to curved surface, is connected with reflecting plate 2, base plate 3, and its inner surface is coated with reflectance coating, and material is identical with reflecting plate 2.
Schematic side view as shown in Figure 2, the linear array arrangement of high-power LED light source 1, for the emergent light axis that makes high-power LED light source 1 obliquely, and a part of light reflects backward upper outgoing through reflecting plate 2, linearly aligned LED and vertical direction out of plumb, but become certain drift angle.
Be illustrated in figure 3 a kind of optical schematic diagram of the high-power LED strip-light lamp based on penalty method, show up 6 for remote wall or curtain, described in shining directly into, a part of light that described high-power LED light source 1 sends shows up 6, according to lambert's light distribution of LED light source, the illumination that light intensity is larger is mapped to 6 the more far-end of showing up, and the illumination that light intensity is less is mapped to 6 the more near-end of showing up. And observe square distance law of reciprocity according to Illumination Distribution, the large light of light intensity is greater than light that light intensity is little to showing up 6 distance to 6 the distance of showing up, therefore show up, the illumination of 6 far-ends is much smaller than the illumination of the near-end of showing up, this just needs us to adopt the light compensation of the reflection illumination 6 of far-end of showing up, thereby obtains the uniform illumination of showing up on 6.
Upper and lower two schematic diagrames that stage lighting is used in conjunction with as shown in Figure 4, another part light that described high-power LED light source 1 sends shows up 6 described in arriving after described reflecting plate 2 reflections, 6 the more far-end (away from light source one end) of showing up described in the reflection ray that light intensity is larger is irradiated to, 6 the more near-end of showing up described in the reflection ray that light intensity is less is irradiated to (near light source one end). Respectively put a lamp in the above and below of stage, the light that upper and lower two lamps send is in the stack on 6 of showing up, and can form Uniform Illumination described showing up on 6, described in show up 6 height can reach tens meters.
