[0020] In order to make the purpose, technical solutions and advantages of the present application more clear, the technical solutions of the present application will be described clearly and completely below. Obviously, the described embodiments are only some of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.
[0021] The specific embodiments of the present application will be described below.
[0022] In view of the above problems existing in the prior art, the application provides a light supplement lamp, which solves the problems of poor light uniformity, large size, insufficient dust prevention and the like in the prior art through the cooperative design of an aspherical light supplement lamp cover, a partitioned optical assembly and a sealing structure, and meanwhile, the feasibility of mass production is taken into account.
[0023] The application provides a light supplement lamp, which comprises: a substrate; a light emitting unit arranged on the substrate; a light supplement lamp cover 10 (as shown in Figure 1 ) covering the outside of the light emitting unit; an optical adjusting assembly located between the light supplement lamp cover and the substrate; The optical adjusting assembly comprises a first optical assembly and a second optical assembly, the first optical assembly is fixed to the inner side central region of the light supplement lamp cover, and the second optical assembly is fixed to the inner side edge region of the light supplement lamp cover and surrounds the first optical assembly; the outer surface of the light supplement lamp cover is aspherical, a closed cavity is formed between the inner surface of the light supplement lamp cover and the substrate; the substrate and the light supplement lamp cover are connected through a sealing structure, the sealing structure comprises an annular sealing ring, the annular sealing ring is embedded in the outer edge groove of the substrate, and the edge of the light supplement lamp cover is fixedly connected with the annular sealing ring through an adhesive; the optical axis of the light emitting unit coincides with the central axis of the curved surface of the light supplement lamp cover.
[0024] The light supplement lamp mainly comprises a substrate, a light emitting unit, a light supplement lamp cover and an optical adjusting assembly located between the light supplement lamp cover and the substrate. The substrate serves as a support structure, the surface of the substrate is provided with the light emitting unit, the light emitting unit usually adopts an LED array and is used to provide a light source required for light supplement. The light supplement lamp cover covers the outside of the light emitting unit, and the outer surface is designed as an aspherical surface. The curved surface structure can effectively correct light path distortion and avoid the overexposure problem caused by the central light intensity aggregation of a traditional spherical lens. A closed cavity is formed between the inner surface of the light supplement lamp cover and the substrate, so that the light path is not disturbed by external dust. The optical adjusting assembly comprises a first optical assembly and a second optical assembly, the first optical assembly is fixed to the inner side central region of the light supplement lamp cover, and the second optical assembly is fixed to the inner side edge region of the light supplement lamp cover and surrounds the first optical assembly.
[0025] The first optical component adopts a microlens array, each microlens has the same curvature radius and equal spacing, the bottom surface is attached to the inner surface of the light supplement lampshade, and the center is aligned with the curved central axis of the light supplement lampshade. This design can uniformly disperse the strong light in the central area of the light emitting unit into parallel light, avoiding overexposure in the center. The curved profile of the second optical component is a quadratic surface, the vertex is aligned with the central axis of the light supplement lampshade, the curved surface extends in the same direction as the curvature of the outer surface of the light supplement lampshade, which can collimate the scattered light at the edge and improve the uniformity of the edge brightness. The substrate and the light supplement lampshade are connected by a sealing structure, which includes an annular sealing ring embedded in the groove on the outer edge of the substrate, and the edge of the light supplement lampshade is fixed with the annular sealing ring by adhesive, forming a double sealing barrier to effectively prevent dust from entering. The optical axis of the light emitting unit coincides with the curved central axis of the light supplement lampshade, ensuring that the light is perpendicular to the optical adjustment component, reducing reflection loss.
[0026] The aspherical light supplement lampshade and the zoned optical adjustment component work together to significantly improve the light uniformity. For example, the central area disperses strong light through the microlens array, and the edge area collimates scattered light through the quadratic surface, making the overall light intensity distribution transition smoothly from the center to the edge. The design of the sealed cavity and the sealing structure not only enhances the dustproof performance, but also simplifies the assembly process. The optical axis alignment further optimizes the optical efficiency and reduces energy loss. In addition, the thickness of the light supplement lampshade gradually decreases from the center to the edge, combined with the compression of the aspherical curved surface, which significantly reduces the overall volume, making it suitable for small devices such as mobile phones and car cameras.
[0027] In some implementations, the first optical component 20 (such as Figure 2 ) is a microlens array, each microlens in the microlens array has the same curvature radius, the spacing between adjacent microlenses is equal, and the bottom surface of the microlens is attached to the inner surface of the light supplement lampshade; the center of the microlens array is aligned with the curved central axis of the light supplement lampshade.
[0028] The microlens array is arranged in a hexagonal or rectangular pattern, the center is aligned with the curved central axis of the light supplement lampshade, and the arrangement direction is parallel to the surface of the substrate. The bottom surface of the microlens is attached to the inner surface of the light supplement lampshade, the vertex is directed towards the light emitting unit, and the height is in a proportional relationship with the thickness of the light supplement lampshade. For example, when the center thickness of the light supplement lampshade is large, the height of the microlens increases accordingly to ensure that the light divergence angle is controllable.
[0029] The micro-lens array is used to convert the Gaussian beam in the center of the light-emitting unit into uniformly distributed parallel light. Due to the high light intensity in the center of the light-emitting unit, the traditional fill light is prone to overexposure in the center. The micro-lens array divides and redistributes the strong light through the regular arrangement of lens units. Each micro-lens diverges the incident light into small-angle parallel light, and the superposition effect of multiple micro-lenses significantly improves the uniformity of the light intensity in the center region. In addition, the uniformity of the micro-lens pitch reduces the processing tolerance sensitivity, for example, the pitch tolerance can be widened to a wider range without significantly affecting the uniformity, thereby improving the production feasibility.
[0030] The regular arrangement and optical correction ability of the micro-lens array reduce the center / horizontal uniformity in the center region to below 1.1 and the center / vertical uniformity to below 1.2. At the same time, the design of the micro-lens and the fill light cover reduces the interface reflection in the light path, further improving the light utilization.
[0031] In some implementations, the light-emitting unit is an LED array, and each LED in the LED array is arranged in a ring shape, and the pitch between adjacent LEDs matches the pitch of the micro-lens array.
[0032] The light output surface of the LED array faces the inner surface of the fill light cover, and the power supply circuit is embedded in the substrate, and the wiring path avoids the projection area of the optical adjustment assembly.
[0033] The ring-shaped distribution of the LED array matches the pitch of the micro-lens array, ensuring that each micro-lens corresponds to an LED light-emitting area, avoiding light overlap or gaps. For example, when the micro-lens pitch is a fixed value, the ring-shaped distribution pitch of the LED needs to be the same or proportional to it to ensure that the light intensity received by each micro-lens is uniform. The embedded design of the power supply circuit reduces external interference and improves electrical safety. The ring-shaped distribution of the LED also optimizes heat management, avoiding light decay caused by local overheating.
[0034] In terms of technical effects, the light output uniformity of the LED array is improved, and the optimized layout of the power supply circuit reduces the risk of electromagnetic interference. The matching design of the ring-shaped distribution and the micro-lens further ensures that the light path covers no dead angle and avoids insufficient edge brightness.
[0035] In some implementations, the curved profile of the second optical assembly 30 (such as Figure 3 ) is a quadratic surface, the vertex of the quadratic surface is aligned with the center axis of the fill light cover, and the quadratic surface is located in the inner edge region of the fill light cover. The extension direction of the quadratic surface is consistent with the curvature of the outer surface of the fill light cover.
[0036] The inner side of the quadratic surface smoothly transitions with the inner surface of the fill light cover, and the edge terminates at the connection between the fill light cover and the substrate and aligns with the edge of the sealing structure.
[0037] The role of the quadric surface is to collimate the scattered light rays in the edge area of the light emitting unit. Due to the large angle and energy dispersion of the edge light rays, it is difficult for traditional fill light to effectively control its distribution, resulting in insufficient edge brightness. The quadric surface converts the large-angle scattered light into small-angle collimated light through its gradually changing curvature, so that it is superimposed with the parallel light in the central area to form a uniform overall light field. For example, a parabolic surface design can reflect the edge light rays and output them in parallel, while a hyperbolic surface achieves a similar effect through refraction.
[0038] The quadric surface improves the brightness uniformity of the edge area, while avoiding the increase in volume caused by redundant light paths. The smooth transition design of the curved surface and the fill light cover further reduces energy loss in the light path.
[0039] In some implementations, the quadric surface is a parabolic surface or a hyperbolic surface, and the radius of curvature of the edge area of the quadric surface is greater than the radius of curvature of the central area.
[0040] The quadric surface is a parabolic surface or a hyperbolic surface, and the radius of curvature of the edge area of the quadric surface is greater than the radius of curvature of the central area. The focal point of the parabolic surface is aligned with the edge area of the light emitting unit, which can reflect the divergent light into parallel light; the tapered curvature of the hyperbolic surface achieves a similar collimation effect through refraction.
[0041] The parabolic surface design is suitable for reflective fill light systems, and the hyperbolic surface design is suitable for transmissive systems. For example, when the fill light cover material is a highly transparent resin, the hyperbolic surface adjusts the light path through refraction; if the inner surface of the fill light cover is coated with a reflective film, the parabolic surface achieves collimation through reflection. The gradual change in the radius of curvature (small in the center and large at the edges) further optimizes the spatial distribution of light, avoiding light spots caused by sudden changes in curvature.
[0042] The quadric surface design of the parabolic surface or the hyperbolic surface improves the collimation efficiency of the edge light rays, while simplifying the processing technology. For example, the parabolic surface can be molded in one step, and the tapered curvature of the hyperbolic surface can be achieved through numerical control machining for high precision.
[0043] In some implementations, the surface of the substrate is provided with a light-reflecting coating, the light-reflecting coating covers the rest of the substrate except for the mounting area of the light emitting unit, and an isolation band is provided between the edge of the light-reflecting coating and the mounting area of the light emitting unit.
[0044] The substrate material is a resin material, such as polycarbonate or ABS plastic, which has high rigidity and heat resistance. The light-reflecting coating is an aluminum film or a silver coating, which is attached to the surface of the substrate through sputtering or spraying process, and the reflectivity is greater than 90%.
[0045] The reflective coating reflects stray light scattered by the light-emitting units towards the substrate back into the light supplement lampshade, reducing light loss. The isolation band prevents the reflective coating from covering the light-emitting unit mounting area, preventing the coating from affecting LED heat dissipation or electrical connection. For example, the isolation band width is slightly larger than the LED package size, ensuring that the electrical contacts are exposed.
[0046] The reflective coating improves the light supplement efficiency, and the low density of the resin material further reduces the overall weight, making it suitable for portable devices. The design of the isolation band takes into account both optical performance and electrical reliability.
[0047] In some implementations, the thickness of the light supplement lampshade gradually decreases from the center to the edge, and the bottom edge of the light supplement lampshade is provided with an annular flange, the inner diameter of which matches the outer diameter of the substrate.
[0048] The thickness of the light supplement lampshade gradually decreases from the center to the edge, and the shape is an axisymmetric structure with an elliptical or circular cross-section. The top center of the light supplement lampshade is provided with a protruding part with continuous curvature with the outer surface curvature, and the bottom edge is provided with an annular flange with an inner diameter matching the outer diameter of the substrate. The material is optical-grade polycarbonate with a gradient change in light transmittance from the center to the edge.
[0049] The thickness gradient design reduces material usage, weight, and production cost while ensuring optical performance. For example, the center area is thicker to support the microlens array, and the edge gradually thins to compress the volume. The matching design of the annular flange and the substrate simplifies the assembly positioning process and improves production efficiency. The gradient change in light transmittance is achieved by adjusting the material doping concentration, with lower light transmittance in the center to suppress overexposure and higher light transmittance at the edge to compensate for brightness.
[0050] The volume of the light supplement lampshade is reduced compared to traditional designs, and the gradient change in light transmittance further optimizes the light intensity distribution. The positioning design of the annular flange controls the assembly error within ±0.1 mm.
[0051] In some implementations, one side of the substrate is provided with a fixing hole that penetrates the substrate and connects with an external device, and the axis of the fixing hole is perpendicular to the surface of the substrate.
[0052] The fixing hole is a threaded hole or a through hole, and the inner wall is provided with a locking thread or a rubber bushing. The edge of the mounting structure is provided with a shock-absorbing pad made of silicone or polyurethane, and the thickness matches that of the substrate.
[0053] The symmetrical distribution of the fixing holes ensures that the light supplement lamp is evenly stressed during installation, avoiding deformation caused by single-point stress. For example, two symmetrical fixing holes are connected to the device shell through bolts, ensuring the stability of the light supplement lamp. The locking thread or rubber bushing enhances the stability of the connection, and the shock-absorbing pad absorbs external vibrations, protecting the internal optical components. The elastic material of the shock-absorbing pad also compensates for the dimensional changes caused by thermal expansion and contraction.
[0054] The design shortens the installation time of the light supplement lamp, and improves the reliability of the equipment in a vibrating environment. The anti-loosening structure avoids the problem of bolt loosening after long-term use.
[0055] In some implementations, the outer side of the annular sealing ring is provided with a dustproof layer, the dustproof layer completely wraps the outer surface of the annular sealing ring, and the edge of the dustproof layer extends to the connection gap between the light supplement lamp cover and the base plate.
[0056] The dustproof layer completely wraps the outer surface of the annular sealing ring and is flush with the outer surface of the light supplement lamp cover. The dustproof layer is made of flexible silicone material and is bonded to the sealing ring through a hot pressing process. The edge extends to the connection gap between the base plate and the light supplement lamp cover, and the surface is provided with a hydrophobic coating.
[0057] The dustproof layer acts as a third dustproof barrier to block the invasion of small particles from the outside of the sealing ring. For example, the flexible silicone material can adapt to the small displacement between the light supplement lamp cover and the base plate, avoiding cracking caused by vibration. The hydrophobic coating prevents water from accumulating in the gap, preventing sealing failure in long-term humid environments. The edge of the dustproof layer extends to the connection gap, ensuring that there is no blind area for protection.
[0058] The dustproof layer enables the light supplement lamp to achieve an IP69K level in extreme environments, significantly extending the service life. The hydrophobic coating can also reduce the frequency of cleaning and maintenance.
[0059] In some implementations, the inner surface of the light supplement lamp cover is provided with a light transmittance gradient layer, the light transmittance of the light transmittance gradient layer gradually increases from the center to the edge, and the light transmittance gradient layer covers the boundary region of the first optical component and the second optical component.
[0060] The light transmittance gradient layer is an optical film or a nano coating formed by a chemical vapor deposition or laser etching process.
[0061] The function of the light transmittance gradient layer is to balance the light intensity difference between the center and the edge. The center region has a lower light transmittance to suppress overexposure, and the edge region has a higher light transmittance to compensate for insufficient brightness. The coverage design of the boundary region ensures smooth transition of light intensity. For example, the light transmittance gradient of the gradient layer in the boundary region is small, avoiding the light spot phenomenon caused by sudden changes in light transmittance.
[0062] The light transmittance gradient layer further improves the overall uniformity and simplifies the design complexity of the optical adjustment component. For example, a single gradient layer can replace the traditional multi-layer filter structure, reducing costs.
