Background Art

[0002] In recent years, with the popular trend of decorative metal curtain walls for commercial high-rise buildings, most of them are assembled with basic curtain wall unit panels in the shape of rectangles, parallelograms, and diamonds to form commercial complexes with their own characteristics. Some buildings represent city landmarks. This type of new style curtain wall structure is generally designed for night scene lighting, which is an indirect lighting method for outdoor landscape lighting. It has different application requirements from the early contour lighting and point light source direct viewing effects. The main application of direct lighting lamps is that people directly watch the luminous surface of the lamps. Its characteristics are high brightness of the luminous surface, dazzling glare and light pollution to the surrounding space; indirect lighting lamps illuminate the curtain wall first, and people watch the various light art effects produced by the indirect light of the curtain wall. Its characteristics are low brightness, uniform and soft luminous surface, glare prevention and light pollution reduction, but it is difficult to take both into account at the same time.

[0003] Therefore, how to achieve uniform illumination of the illuminated surface of metal curtain walls such as parallelogram, rhombus and triangular unit panels, prevent glare and reduce stray light pollution while meeting the requirements of a collection of optical lens parts urgently needs to be solved. Summary of the invention

[0004] The purpose of the present invention is to provide a TIR total reflection three-dimensional spatial distribution polarized lens system, which mainly solves the problems existing in the above-mentioned prior art. It adopts optical lens parts designed according to non-imaging optical principles to make secondary optical distribution of the cosine-like spatial distribution of the light intensity of the LED light source, which can solve the advantages of asymmetric position relationship between the lamp and the illuminated surface and uniform illumination of the irregular illuminated surface, and prevent the non-controllable stray light of the LED light source from causing disabling glare and light pollution. At the same time, it can also solve the advantages of combining multiple color light-emitting chips into a packaged LED light source (such as RGBW, RGB, CW+WW), so that the various color light beams are controllable through the TIR lens, and the output light beams of various colors are mixed evenly and softly.

[0005] The technical solution of the present invention is:

[0006] A TIR total reflection three-dimensional spatial distribution polarized lens system, characterized in that it comprises an LED light source, a TIR total reflection lens, and a black extinct, opaque, and stray light control sheet; wherein:

[0007] The LED light source disk is welded on a PCB board located in a horizontal position so that the maximum light intensity direction of the emitting surface is vertically upward;

[0008] The TIR total reflection lens includes an LED light source light entry position, a light entry inner hole arc frosted process curved surface, a TIR total reflection surface, a beam deflection H direction inclined surface, a beam deflection V direction inclined surface, and a light output surface light mixing aspherical microstructure bead array;

[0009] The light inlet position of the LED light source is located on the LED light source and ensures that the LED light source is on a PCB board in a horizontal position, so that the maximum light intensity direction of its light-emitting surface is vertically upward; when the light beam enters the frosted surface of the light inlet inner hole of the lens, the various color light beams emitted by the LED light source containing the multi-chip group are transmitted after the initial color mixing through the surface, and the deviation tolerance of the incident angle is increased to reduce the deviation of the incident angle of each primary color light beam due to the physical size of the multi-chip inside the LED light source and the relative optical center position offset, avoid serious separation of the emitted light beams of each primary color light beam, and perform the first transmission correction of the color cast; after the light is further reflected by the TIR total reflection surface, this interface is an asymmetric surface of a quadratic fitting curve, according to the total reflection of the light from the dense medium to the sparse medium The principle and light flux transfer technology enable light beams with different incident angles transmitted from the frosted curved surface of the light-entering inner hole to be fully reflected to the maximum extent, and perform secondary distribution of light energy to increase the utilization efficiency of light energy; enable the light beam to enter the primary light-control deflection plane with less loss: the light beam is deflected on the H-direction inclined plane, so that the emission direction of the controllable light beam is precisely controlled by this inclined plane at the spatial azimuth angle H; the controllable light beam emitted from the H-direction inclined plane of the lens beam deflection is refracted from the V-direction inclined plane of the beam deflection to the spatial target plane through the secondary light-control deflection, and its deflection angle is precisely controlled by it in the spatial V direction; the controllable light beam reaches the light-mixing aspherical microstructure bead array on the light-exiting surface after the above-mentioned secondary deflection, and the light beam scattered by this unit microstructure achieves secondary light mixing, which can enhance the tolerance range of light beam color difference;

[0010] The black matte, light-proof and stray light control sheet can block the uncontrollable stray light generated by light reaching the side wall of the lens within the optical cavity, and prevent it from overflowing into the space outside the optical cavity.

The frosted surface of the light inlet hole performs a diffuse transmission correction mixing to increase the deviation tolerance of the incident angle.

[0013] The TIR total reflection three-dimensional spatial distribution polarized lens system is characterized in that: the TIR total reflection surface is formed by rotating the generatrix of the aspheric quadratic fitting curve around the central axis by 360°. According to the principle of total reflection of light from a denser medium to a less dense medium, light beams with different incident angles transmitted from the frosted surface of the lens light inlet inner hole can be fully reflected to the maximum extent, thereby increasing the utilization rate of light energy and allowing the light beam to enter the precise light control deflection plane with less loss in the optical path.

[0014] The TIR total reflection three-dimensional spatial distribution polarized lens system is characterized in that the function of the H-direction inclined plane for beam deflection is that the peak light intensity direction of the Lambertian-type light distribution beam initially emitted by the LED light source is vertically upward to the horizontal plane, and the emission direction of the controllable light beam is fully reflected by the TIR total reflection surface, and the inclined plane is precisely controlled at the spatial H azimuth angle.

[0015] The TIR total reflection three-dimensional spatial distribution polarizing lens system is characterized in that the function of the beam deflection V-direction inclined plane is that the precisely controllable light beam emitted by the lens beam deflection H-direction inclined plane is refracted to the spatial target plane through the lens beam deflection V-direction inclined plane, and its deflection angle in the spatial V direction is precisely controlled by it.

[0016] The TIR total reflection three-dimensional spatial distribution polarized lens system is characterized in that the function of the light-emitting surface mixing aspherical microstructure bead array is that the light beam emitted by the TIR total reflection surface, the beam deflection H-direction inclined surface and the beam deflection V-direction inclined surface is scattered by this unit microstructure to expand the beam angle, and then the multiple arrays are superimposed and contributed to make the light beam emitted from the frosted curved surface of the light-inlet inner hole achieve secondary light mixing, thereby enhancing the tolerance range of the color difference of the light beam emitted by LED light sources from different manufacturers.

[0017] The TIR total reflection three-dimensional spatial distribution polarized lens system is characterized in that the function of the black extinct, opaque and stray light control sheet is to block the uncontrollable stray light that reaches the side wall of the lens through the non-total reflection transmitted light in the lens optical cavity through the TIR total reflection surface in the optical cavity and is blocked in the optical cavity, and will not overflow into the space outside the optical cavity.

[0018] By using the optical system of the present invention, the light beam generated by the secondary light distribution of the lens is precisely and quantitatively controlled in the two directions of H and V in three-dimensional space; the internal black extinction and opaque stray light control sheet is used in combination to control the stray light, and the angle is precisely controlled while the lens itself has the function of preventing glare caused by the overflow of stray light; the lens includes an arc frosted process surface of the inner light inlet hole and a light mixing aspherical microstructure bead array on the light output surface, so that multiple color light-emitting chips are combined into a packaged LED light source (such as RGBW, RGB, CW+WW), so that the various color light beams are controllable through the TIR lens, and the various colors of the output light beams are mixed evenly and softly.

[0034] See also Figure 1-6 The present invention discloses a TIR total reflection three-dimensional spatial distribution polarized lens system. As shown in the figure: it includes an LED light source, a TIR total reflection lens, and a black extinct and opaque stray light control sheet 7; wherein: the LED light source disk is welded on a PCB board located in a horizontal position, so that the maximum light intensity direction of its emitting surface is vertically upward; the TIR total reflection lens includes an LED light source light inlet position 1, a light inlet inner hole arc frosted process surface 2, a TIR total reflection surface 3, a beam deflection H direction inclined surface 4, a beam deflection V direction inclined surface 5, and a light output surface mixed light non-spherical microstructure bead array 6.

[0035] The grinding process of the light-inlet inner hole arc grinding process curved surface 2 uses compressed air as a power source, and sprays diamond sand with a particle size of 80 to 120 at a high speed to change the shape of the mold surface and obtain different degrees of roughness.

[0036] The light-emitting surface light-mixing aspherical microstructure bead array 6 has a bead array unit size of 0.25 mm to 0.5 mm with variable linear dimensions, and adopts a regular hexagonal array or a circular array.

[0037] In the system of the present invention, the LED light source light inlet position 1 is located on the LED light source and ensures that the LED light source is on a PCB board in a horizontal position, so that the maximum light intensity direction of the light-emitting surface is vertically upward; when the light beam enters the lens light inlet inner hole arc frosted process curved surface 2, each color light beam emitted by the LED light source containing a multi-chip group is transmitted after the initial color mixing through the curved surface, and the deviation tolerance of the incident angle is increased to reduce the deviation of the incident angle of each primary color light beam due to the physical size of the multi-chip inside the LED light source and the relative optical center position offset, avoid serious separation of the emitted light beams of each primary color light beam, and perform the first transmission correction of the color cast; after the light is further reflected by the TIR total reflection surface 3, this interface is an asymmetric surface of a quadratic fitting curve, according to the total occurrence of the light from the optically dense medium to the optically sparse medium The principle of reflection and light flux transfer technology ensure that light beams with different incident angles transmitted from the frosted curved surface 2 of the light inlet inner hole can all be fully reflected to the maximum extent, and the light energy can be secondary distributed to increase the utilization efficiency of the light energy; the light beam is allowed to enter the primary light control deflection plane with less loss: the light beam is deflected on the H direction inclined surface 4, so that the emission direction of the controllable light beam is precisely controlled by this inclined surface at the spatial azimuth angle H; the controllable light beam emitted from the lens beam deflection H direction inclined surface 4 is refracted from the beam deflection V direction inclined surface 5 to the spatial target plane through the secondary light control deflection, and its deflection angle is precisely controlled by it in the spatial V direction; the controllable light beam reaches the light emitting surface mixed non-spherical microstructure bead array 6 after the above-mentioned secondary deflection, and the light beam scattered by this unit microstructure achieves a secondary light mixing effect, which can enhance the tolerance range of the light beam color difference.

[0038] The black matte, opaque, stray light control sheet 7 can block the uncontrollable stray light generated by the light reaching the side wall of the lens within the optical cavity, and prevent it from overflowing into the space outside the optical cavity.

[0039] In the present invention, the lamp is located on a horizontal installation plane, and the internal PCB board is also placed horizontally.

[0040] In the present invention, the frosted curved surface 2 of the light inlet hole allows each primary color light beam emitted by the LED light source multi-chip group to be transmitted through the air to the scattered light mixing interface for initial light mixing, so that each primary color light beam has an incident angle deviation due to the offset of the physical size and relative position of the multi-chips inside the LED light source, resulting in excessive separation of the emitter light of each primary color light beam and serious color cast and mottled visual effects. The frosted curved surface of the light inlet hole performs a diffuse transmission correction mixing to increase the deviation tolerance of the incident angle.

[0041] In the present invention, the TIR total reflection surface 3 is formed by rotating the generatrix of the aspheric quadratic fitting curve around the central axis by 360°. Based on the principle of total reflection of light from a denser medium to a less dense medium, light beams of different incident angles transmitted from the frosted curved surface 2 of the inner light inlet hole of the lens can be totally reflected to the maximum extent, thereby increasing the utilization rate of light energy and allowing the light beam to enter the precise light control deflection plane with less loss in the optical path.

[0042] In the present invention, the function of the H-direction inclined plane 4 for beam deflection is that the peak light intensity direction of the beam with Lambertian light distribution initially emitted by the LED light source is vertically upward on the horizontal plane, and the direction of the controllable beam emitted by the TIR total reflection surface 3 is precisely controlled by this inclined plane at the spatial H azimuth angle.

[0043] In the present invention, the function of the beam deflection V-direction inclined plane 5 is that the precisely controllable beam emitted by the lens beam deflection H-direction inclined plane 4 is refracted to the space target plane through the lens beam deflection V-direction inclined plane 5, and its deflection angle in the space V direction is precisely controlled by it.

[0044] In the present invention, the function of the light-emitting surface mixing aspherical microstructure bead array 6 is that the light beam emitted by the TIR total reflection surface 3, the beam deflection H-direction inclined plane 4 and the beam deflection V-direction inclined plane 5 is scattered by this unit microstructure to expand the beam angle, and then the contributions of multiple arrays are superimposed on each other, so that the light beam emitted by the frosted process curved surface 2 of the light-inlet inner hole can achieve secondary light mixing, thereby enhancing the tolerance range of the color difference of the light beam emitted by LED light sources from different manufacturers.

[0045] In the present invention, the function of the black matte, opaque and stray light control sheet 7 is to block the uncontrollable stray light that reaches the side wall of the lens through the non-total reflection transmitted light in the lens optical cavity through the TIR total reflection surface 3 in the optical cavity and prevent it from overflowing into the space outside the optical cavity.

[0046] See also Fig. 9 , 10 , which are descriptions of the optical paths of the light rays in the system of the present invention.

[0047] 1) Design description of the deflection angle of the characteristic light 0A path:

[0048] like Fig. 9, the light OA emitted from the center O of the LED light source enters the lens through point A at the side 21 of the lens surface 2. The refractive index of air is n, and the refractive index of the lens material is n'. According to the law of refraction, nsin(i) = n'sin(i') (n is taken as 1), and refracts from point A to point A1 at the TIR total reflection surface 3. By adjusting the curvature and normal direction of point A1, i">arcsin(n'), the light AA1 is totally reflected, that is, i" = i"', and the emission direction of the light A1A2 is perpendicular to the inclined plane 4 in the H direction of the beam deflection; thus, the deflection angle between the light A1A2 and the horizontal center line is α = 90°-H angle, recorded as α(H) = f1(H). When the emission direction of the light A1A2 is not perpendicular to the inclined plane 4 in the H direction of the beam deflection, f1 can be appropriately changed; such as Fig.10 The light beam A1A2 is incident on the inclined plane 5 in the direction of beam deflection V, the incident angle is V angle, n'sin(V)=nsin(β), the output angle is β=arcsin(n'sinV), and then is emitted after being scattered and uniformed by the light-emitting surface mixed light aspherical microstructure bead array 6.

[0049] 2) Design description of the deflection angle of the characteristic light 0B path:

[0050] like Fig. 9 , the light OB emitted from the center O of the LED light source enters the lens through point B on the lens surface, and follows the refraction principle as mentioned above. The direction of light BB1 is perpendicular to the inclined plane 4 in the direction of the beam deflection H; therefore, the angle between the light BB1 and the horizontal center line is also α = 90°-H, recorded as α(H) = f2(H). The subsequent optical path follows the same principle, and is emitted after passing through the inclined plane 5 in the direction of the beam deflection V and the light-emitting surface mixed aspherical microstructure bead array 6.

[0051] The effects of using the optical system of the present invention are as follows Fig.11 , 12 The light beam generated by the secondary light distribution of the lens is precisely and quantitatively controlled in the two directions of H and V in three-dimensional space; including the internal black extinction and opaque stray light control sheet to control the stray light, the angle is precisely controlled, and the lens itself has the function of preventing the glare caused by the overflow of stray light; including the frosted process surface of the inner hole of the lens for light entry and the light-mixing aspherical micro-structure bead array on the light-emitting surface, so that multiple color light-emitting chips are combined into a packaged LED light source (such as RGBW, RGB, CW+WW), so that the various color light beams are controllable through the TIR lens, and the various colors of the output light beams are mixed evenly and softly.

[0052] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
