Description
Technical Field
The invention relates to the field of lighting lamps, in particular to an LED wall washer.
Background
The outer wall of a high-rise building is usually provided with a wall washing lamp, so that the wall washing lamp can be used for lighting in a residential area and has good interest and decoration. The prior wall washing lamp generally adopts a fixed structure, and if the interest is further improved, a power component is required to be configured to enable the lamp light to dynamically move on a wall body. However, even if a common power mechanism is provided, the dynamic light generated by the power mechanism changes according to a fixed rule, for example, the patent application No. 2015107466492, which can form a wavy light pattern during the lighting process; however, the fluctuation rule is fixed, and after the light fluctuation effect is viewed for a short time, the aesthetic fatigue is easy to generate, and the interest of the light fluctuation rule is still limited.
Disclosure of Invention
In view of the above problems, an object of the present invention is to provide a dynamic LED wall washer, which can form a dynamic illumination effect on a wall surface, and the dynamic style has a certain randomness, so as to improve the interest of the wall washer to a greater extent.
The technical scheme adopted by the invention for solving the technical problems is as follows: the dynamic LED wall washing lamp comprises a base extending horizontally along a wall, wherein a horizontally extending LED lamp strip is arranged on the base and generates illumination vertical to the wall surface; a base shaft is fixed in front of the LED light bar, and short prisms capable of freely rotating around the base shaft are equidistantly arranged on the base shaft; the surfaces of the short prisms are mirror surfaces; each adjacent short prism is connected through a torsion spring; the short prism at the outermost end is driven by a stepping motor fixed on the base; and a stepping motor controller is also arranged in the base, and the controller enables the rotating shaft of the stepping motor to rotate by a random angle at intervals.
Preferably, a cavity is formed at one end, opposite to each other, of each short prism, and the torsion spring is arranged in the cavity, so that a gap which is not more than 2mm is reserved between the short prisms.
Preferably, the polygonal edges of each of the short prisms are rounded to provide soft edges to the reflected spots of the short prisms.
Preferably, the surface of the short prism is a semi-transparent mirror surface, the short prism is filled with water, and the water is not filled in the short prism; therefore, part of light generated by the LED lamp strip enters the short prism, irradiates on water floating foam generated in the rotation process of the short prism and is scattered outwards; therefore, the light spots reflected by the short prisms outwards contain floating light shadows, and the light shadows of the wall washing lamp are further embellished to improve the interest of the wall washing lamp; further, foaming agents such as detergents may be incorporated into the water to form more froth.
The invention has the beneficial effects that: in the lighting process of the dynamic LED wall washing lamp, the stepping motor rotates the short prism at the starting end by one rotation angle at each time, then the short prism keeps static along with the stepping motor, and the angular momentum generated by the short prism is transmitted to the short prism at the tail end in sequence through the torsion springs among other short prisms; in the process, each short prism after the beginning end rotates by the same rotation angle beta as the short prism at the beginning end in sequence, and the short prism at the tail end rotates by a rotation angle larger than beta under the action of inertia (if the mechanical energy loss is not considered, the short prism at the tail end rotates by a rotation angle close to 2 beta), at the moment, each short prism in front of the short prism at the tail end is dragged to continue rotating until being limited by the short prism fixed at the beginning end, so that the angular momentum is transmitted back and forth among other short prisms except the short prism at the beginning end until being consumed by friction loss; in the process, each short prism rotates, and the intersection angle of the surface of each short prism and the illumination generated by the LED lamp strip is continuously changed in a fixed period, so that each short prism reflects light spots swinging back and forth on the wall to form a dynamic light and shadow effect; when the initial rotation angle beta of the initial short prism is different, the following angles of the short prisms are different, and when the following angle exceeds the circumferential angle corresponding to each surface of the short prism, the positions of the light spots reflected by the short prisms jump (jump from the last position to the initial position), therefore, when the initial rotation angle beta of the initial short prism is different, the position jump times of the light spots reflected by the following short prisms are different, therefore, the position difference of the reflected light spots of the adjacent short prisms in the vertical direction is small or large (the position of one light spot jumps right), the large position difference in the vertical direction is recorded as a break, the initial rotation angle beta of the initial short prism is different, the limit rotation angle to which the final short prism rotates is also different, at the moment, each short prism is in an instantaneous static state, and the position of the break is different according to the difference of the initial rotation angle beta, the arrangement pattern of each light spot when the light spot is static on the wall body is different due to different initial turning angles beta, so that the light spot groups are arranged into a random pattern at intervals in the process of moving back and forth, and the wall washing interest of the light spot groups is improved.

Detailed Description
In the embodiment shown in fig. 1, the dynamic LED wall washer comprises a base 1 extending horizontally along a wall, wherein a horizontally extending LED light bar 2 is arranged on the base 1, and the LED light bar 2 generates illumination perpendicular to the wall; a base shaft 3 is fixed in front of the LED light bar 2, and short prisms 4 capable of freely rotating around the base shaft 3 are equidistantly arranged on the base shaft 3; the surface of the short prism 4 is a mirror surface; each adjacent short prism 4 is connected through a torsion spring 5; the short prism 4 at the outermost end is driven by a stepping motor 6 fixed on the base 1; a stepping motor controller (not shown) is further arranged in the base 1, and the controller enables the rotating shaft of the stepping motor 6 to rotate by a random angle at intervals.
In this embodiment, a cavity 40 is formed at one end of each short prism 4 facing each other, and the torsion spring 5 is disposed in the cavity 40, so that a gap of not more than 2mm is left between each short prism 4.
In the lighting process of the dynamic LED wall washing lamp, the stepping motor 6 rotates the short prism 4a at the initial end by one rotation angle at random, then the short prism 4a keeps static along with the stepping motor 6, and the angular momentum generated by the short prism 4a is transmitted to the short prism at the tail end in sequence through the torsion springs 5 between other short prisms 4; during this process, each short prism 4 after the start end rotates through the same rotation angle β as the short prism 4a at the start end in turn, while the short prism at the end rotates through a rotation angle larger than β under the inertia effect (if the mechanical energy loss is not considered, the short prism at the end will rotate through a rotation angle close to 2 β), at this time, the short prism at the end pulls each short prism ahead to continue rotating until being limited by the short prism 4a at the start end, and thus, the angular momentum is transmitted back and forth between the short prisms 4 other than the short prism 4a at the start end until being consumed by the friction loss; in the process, each short prism rotates, the intersection angle of the surface of each short prism and the LED light bar 2 for generating illumination continuously changes in a fixed period, so that each short prism 4a and 4 reflects light spots swinging back and forth on the wall to form a dynamic light and shadow effect.
As shown in fig. 2, during the rotation of the short prism 4, the light moves from one side of one reflection surface of the short prism 4 to the other side, the incident angle continuously changes, resulting in a continuous change of the reflection angle, thereby forming a continuously moving light spot, and when the short prism 4 continues to rotate, the light is emitted over the edge to irradiate the next reflection surface, at which time, the light spot jumps to the starting end, and the moving process of the previous cycle is continuously repeated. It is noted that, assuming that the short prism 4 is an N-prism, one movement period of the light spot corresponds to the time taken for the short prism 4 to rotate by 2 pi/N. The range of the light spot generated by each short prism 4 moving back and forth is shown by the dashed area in fig. 3.
For the wall washing lamp, when the initial rotation angle β of the short prism 4a at the initial end is different, the following angle of each short prism 4 is also different, and when the following angle exceeds the circumferential angle corresponding to each surface of the short prism 4, the position of the light spot reflected by the short prism jumps (jumps from the last position to the initial position), so that when the initial rotation angle β of the short prism 4a at the initial end is different, the position jumping times of the light spot reflected by each short prism at the back are also different, therefore, the position difference of the light spot reflected by each adjacent short prism 4 in the vertical direction is small or large (the position of one light spot jumps right), it is recorded that the large position difference in the vertical direction is an interruption, when the initial rotation angle β of the short prism at the initial end is different, the limit rotation angle to which the short prism at the end rotates is also different, and at this time, each short prism 4 is in the instantaneous static state (after this state, the short prisms at the tail end start to drive the short prisms to reversely twist), in the state, the interruption positions are different due to different initial rotation angles beta, namely, the arrangement pattern of each light spot when the light spot is static on the wall body is different due to different initial rotation angles beta, therefore, the light spot groups are arranged into a random pattern at intervals in the process of moving back and forth, and the wall washing interest of the light spot groups is improved.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
