DETAILED DESCRIPTION
[0029] The advantages and effects of the present application can be easily understood by those skilled in the art from the disclosure of the present specification.
[0030] The present application discloses a rotating switching light emitting form spotlight structure and a spotlight using the same. The rotating lens and the composite light reflection cup are coaxially arranged and rotationally matched to realize flexible switching of multiple light emitting forms, such as spotlight, floodlight, wall washing, etc. The spotlight is suitable for commercial lighting, home decoration, etc. The present application will be described in detail below with reference to the drawings and specific embodiments.
[0031] Embodiment one The present embodiment provides a spotlight structure capable of rotating switching light emitting form, which is suitable for LED spotlight. Referring to the drawings, Figures 1 to 4 The spotlight structure comprises a rotating lens 1 and a composite light reflection cup 2. The rotating lens 1 and the composite light reflection cup 2 can realize two light emitting states of small angle light emitting and small angle combined with large angle light emitting. The relative position of the rotating lens 1 and the composite light reflection cup 2 is changed by manually rotating the rotating lens 1, so as to switch the light emitting state.
[0032] Specifically, the rotating lens 1 and the composite light reflection cup 2 are coaxially arranged and rotationally matched. The rotating lens 1 is a rotary body, and the light exit port 116 is arranged along the rotary axis of the rotating lens 1. The rotating lens 1 comprises a rotating end surface 110 and a lens end 120. The rotating end surface 110 is used for large angle light emitting, and the lens end 120 is used for small angle light emitting. The lens end 120 is provided with an incident port 111 and a main light exit portion 112. A plurality of lens grooves 113 and total reflection portions 114 are arranged around the incident port 111 at intervals, and the number of the lens grooves 113 and the total reflection portions 114 is equal. The rotating lens 1 is made of light transmission material, which can be optical grade PMMA or PC material. The side surface of the lens end 120 is a uniform arc surface, and the arc surface is configured to reflect the light source light to the main light exit portion 112. The light source light enters from the incident port 111, part of the light directly exits from the main light exit portion 112, and the scattered light entering the lens end 120 is reflected from the total reflection portion 114 and exits from the main light exit portion 112.
[0033] The composite reflector cup 2 comprises an inner reflector cup 210 and an outer reflector cup 220. The inner side of the inner reflector cup 210 and the inner side of the outer reflector cup 220 are reflective surfaces, which can be made of aluminum or silver-plated PC. The inner reflector cup 210 and the outer reflector cup 220 are connected by a ring-shaped bottom plate. The inner reflector cup 210 is connected to the inner circular edge of the ring-shaped bottom plate, and the outer reflector cup 220 is connected to the outer circular edge of the ring-shaped bottom plate. The inner circular part of the ring-shaped bottom plate is used to set the light source. It should be noted that the outer diameter of the ring-shaped bottom plate is not less than the outer diameter of the main light emitting part 112 of the lens end 120.
[0034] In this embodiment, the inner reflector cup 210 is used to adjust the light emitting form by matching the lens groove 113 of the lens end 120. The shape of the inner reflector cup 210 is set according to the shape of the outer side of the lens end 120, so that the inner side of the inner reflector cup 210 matches the outer side of the lens end 120, that is, the outer side of the lens end 120 is covered by the inner reflector cup 210. The inner reflector cup is provided with a plurality of light transmission openings 211 corresponding to the lens groove 113 of the lens end 120, which is used to cooperate with the lens groove 113 to transmit part of the light of the light emitting port 116. The accurate correspondence between the lens groove 113 and the light transmission opening 211 makes the edge of the auxiliary light spot clear and the transition natural. When the lens groove 113 and the lens opening have an overlapping part, the light transmitted through the lens groove 113 and the light transmission opening 211 is reflected to the rotating end surface 110 by the outer reflector cup to form a large-angle light emission. When the inner reflector cup 210 completely shields each lens groove 113, the inner reflector cup 210 cooperates with the lens end 120 to form an integral reflector cup structure and a small-angle light emission form, and the light of the light source is reflected by the total reflection part 114 and the inner reflector cup 210 and emitted by the main light emitting part 112.
[0035] By forming part of the light of the light source into a small-angle light emission and another part of the light into a large-angle light emission, the spotlight structure in this embodiment can expand its illumination range when applied to LED spotlights and other lamps, and is more flexible in application. At the same time, by rotating the rotating lens 1, the size of the overlapping part of the lens groove 113 and the lens opening can be adjusted, and the proportion of the large-angle light emission can be adjusted.
[0036] The spotlight structure in this embodiment has two light emission forms, more application scenarios, and can realize the switching between the small-angle light emission form and the small-angle combined with large-angle light emission form by rotating the lens 1 and the composite reflector cup 2, which is simple and convenient to operate.
[0037] Embodiment Two This embodiment further specifically describes the spotlight structure of the present application. In this embodiment, reference is made to the drawings Figures 1 to 5The rotating spotlight structure for switching light emission forms includes a rotating lens 1 and a composite reflector cup 2 coaxially arranged and rotationally matched, wherein the rotating lens 1 includes a rotating end face 110 and a lens end 120; the lens end 120 is provided with an incident port 111 and a main light emission part 112, a plurality of lens grooves 113 and total reflection parts 114 are arranged around the incident port 111, and the lens grooves 113 and the total reflection parts 114 are equal in number and arranged at intervals; the composite reflector cup 2 includes an inner layer reflector cup 210 and an outer layer reflector cup 220; the inner side of the inner layer reflector cup 210 is attached to the outer side of the lens end 120, and a plurality of light transmission openings 211 are arranged corresponding to the lens grooves 113.
[0038] The rotating lens 1 is of light transmission material, and the inner sides of the inner layer reflector cup 210 and the outer layer reflector cup 220 are all light reflecting surfaces. The side of the lens end 120 is a uniform arc surface, and the arc surface is configured to reflect light from a light source to the main light emission part 112.
[0039] In this embodiment, the side of the lens end 120 is equally divided into N parts (N is an even number), of which N / 2 parts are configured as lens grooves 113, and the other N / 2 parts are configured as total reflection parts 114, and the lens grooves 113 and the total reflection parts 114 are arranged at intervals. The lens grooves 113 extend from the small-diameter end of the lens end 120 to the main light emission part 112, and at the same time, a total reflection part 114 is formed between any two adjacent lens grooves 113. The shape of the light transmission opening 211 is configured as the shape of the lens groove 113 formed on the outer side of the lens end 120, and at the same time, according to the number and arrangement interval of the lens grooves 113, the light transmission openings 211 are arranged correspondingly, so that after the lens end 120 and the inner layer reflector cup 210 are attached, by rotating the rotating lens 1, the inner layer reflector cup 210 can completely close the lens grooves 113, or the lens grooves 113 coincide with the light transmission openings 211, and when the rotating lens 1 is rotated by an angle of 360° / N each time, the lens grooves 113 can be switched between being completely opened and being completely closed.
[0040] For example, when N is set to 12, the side of the lens end 120 is equally divided into 12 equal parts, of which 6 parts are configured as lens grooves 113, and 6 parts are configured as total reflection parts 114, and each part of the lens groove 113 or the total reflection part 114 occupies 30° of the entire cross section of the lens end 120. When switching from the small-angle light emission form to the small-angle combined large-angle light emission form, the rotating end face 110 can be rotated by 30° clockwise or counterclockwise to complete the switching. At the same time, during the switching from the small-angle light emission form to the small-angle combined large-angle light emission form, the rotating end face 110 can be rotated as needed to configure the ratio of small-angle light emission and large-angle light emission. For example, only 10° is rotated, and the large-angle light emission reaches 30% of the maximum light emission.
[0041] For example, when N is set as 24, the side surface of the lens end 120 is equally divided into 24 parts, 12 of which are configured as the lens grooves 113 and the other 12 of which are configured as the total reflection portions 114, each of which occupies 15° of the whole cross section of the lens end 120. When switching from the small-angle light emitting mode to the small-angle combined with large-angle light emitting mode, the rotating end surface 110 is rotated by 15° clockwise or counterclockwise to complete the switching. Meanwhile, during the switching from the small-angle light emitting mode to the small-angle combined with large-angle light emitting mode, the rotating end surface 110 can be rotated according to the need to configure the ratio of the small-angle light emitting and the large-angle light emitting. For example, only 5° is rotated, and the large-angle light emitting reaches 30% of the maximum light emission.
[0042] By setting the number of equal divisions of the side surface of the lens end 120, the density of the large-angle light emitting spot formed on the rotating end surface 110 can be changed, and thus the light emitting effect of the large-angle light emitting can be changed.
[0043] In this embodiment, the depth of the lens groove 113 and the depth of the incident port 111 are adjusted, and the depth of the lens groove 113 is used to control the light distribution of the large-angle light emitting.
[0044] This embodiment gives a specific setting form of the spotlight structure of the present application. By setting the lens groove 113 and the total reflection portion 114 to have the same width, the effective switching between the small-angle light emitting and the small-angle combined with large-angle light emitting is ensured. Meanwhile, by specifically setting the number of equal divisions of the side surface of the lens end 120, the light emitting effect of the large-angle light emitting can be changed. The more the number of equal divisions of the side surface of the lens end 120, the more the spot formed on the rotating end surface 110 under the small-angle combined with large-angle light emitting mode, and the more uniform the light emission.
[0045] Embodiment Three This embodiment further specifically describes the spotlight structure of the present application on the basis of Embodiment Two. In this embodiment, the outer light cup is provided with a plurality of reflection plates 221 arranged opposite to the light transmission openings 211. The reflection plate 221 is in the shape of a fan with a uniform arc surface, and the arc surface is configured to refract the light emitted by the light transmission opening 211 to the rotating end surface 110. The height dimension of the reflection plate 221 is not less than the height dimension of the light transmission opening 211. When the lens groove 113 is completely opened, part of the light emitted by the light source passes through the lens groove 113 and the light transmission opening 211 to the reflection plate 221, and is reflected to the rotating end surface 110 via the reflection plate 221 to form the large-angle light emitting.
[0046] Specifically, referring to the drawings Figures 6 to 8The height dimension of the reflecting plate 221 is not less than the height dimension of the light-transmitting opening 211, and further, the side surface of the reflecting plate 221 on the same side as the light-transmitting opening 211 is in the same plane as the plane passing through the central axis of the composite reflecting cup 2, which can ensure that all the light transmitted by the light-transmitting opening 211 is reflected by the reflecting plate 221.
[0047] In the embodiment, the reflecting plate 221 has a hyperboloid structure, which can reflect the light transmitted by the lens end 120 while producing appropriate diffusion, expand the light spot area produced by the large-angle light emission on the rotating end surface 110, and make the large-angle light emission more uniform. Compared with the setting form of the outer layer reflecting cup 220 in the above-mentioned embodiment two, the reflecting plate 221 in the embodiment is more flexible in the specific setting of the large-angle light emission. For example, the hyperboloid is configured such that when the light-transmitting opening 211 is completely coincident with the lens groove 113, i.e., the large-angle light emission form reaches the maximum light emission, the light reflected by the reflecting plates 221 forms a complete light ring on the rotating end surface 110. Or, when the equal division number N of the side surface of the lens end 120 is large, in the process of switching from the small-angle light emission to the small-angle light emission combined with the large-angle light emission, i.e., the process of gradually increasing the coincidence degree of the lens groove 113 and the light-transmitting opening 211, the hyperboloid of the reflecting plate 221 is configured such that the light spots produced by adjacent reflecting plates 221 have partial fusion, and a complete light ring is formed on the rotating end surface 110. In the process of gradually increasing the coincidence degree of the lens groove 113 and the light-transmitting opening 211, the light ring of the rotating end surface 110 reflects the gradually increasing brightness.
[0048] The embodiment can more flexibly set the large-angle light emission form by setting the outer layer reflecting cup 220 as the reflecting plate 221. Specifically, the reflecting plate 221 is set as a hyperboloid, so that the large-angle light emission on the rotating end surface 110 is more uniform.
[0049] Embodiment four The embodiment further specifically illustrates the structure of the spotlight of the application. In the embodiment, the rotating lens 1 and the composite reflecting cup 2 are coaxially arranged and rotationally matched, wherein the rotating lens 1 comprises a rotating end surface 110 and a lens end 120; the lens end 120 is provided with an incident port 111 and a main light-emitting part 112, a plurality of lens grooves 113 and total reflection parts 114 are arranged around the incident port 111, and the number of the lens grooves 113 and the total reflection parts 114 is equal and they are arranged at intervals; the composite reflecting cup 2 comprises an inner layer reflecting cup 210 and an outer layer reflecting cup 220; the inner side surface of the inner layer reflecting cup 210 is attached to the outer side surface of the lens end 120, and a plurality of light-transmitting openings 211 are arranged corresponding to the lens grooves 113.
[0050] Reference is made to the accompanying drawings Figure 2The rotating end surface 110 is annular and uniformly densely distributed with a plurality of beads 130, the surface of the beads 130 is smooth, the beads 130 facilitate the rotation of the rotating end surface 110, and the light emitted through the rotating end surface 110 is further scattered. The beads 130 are integrally formed on the rotating end surface 110, and the surface of the beads 130 is arc-shaped. The beads 130 are regularly arranged, a plurality of bead circles are arranged on the rotating end surface 110, and the width of the beads 130 gradually decreases from the outer circle to the inner circle. The light reflected by the reflecting plate 221 is further scattered by the beads 130 of the rotating end surface 110, and the light scattering effect of the large-angle light emitting part is improved. The structure of the beads 130 is combined with the convex lens 115, which not only ensures the sharpness of the central light spot, but also realizes the soft transition of the peripheral light, and the overall light quality is significantly improved.
[0051] In some other embodiments in the present embodiment, the arrangement of the beads 130 can be other specific settings, for example, the light scattering effect gradually increases from the inner circle to the outer circle of the rotating end surface 110, or the scattering effect of the rotating end surface 110 is uniform, and those skilled in the art can set the arrangement form of the beads 130 according to the expected effect. Furthermore, those skilled in the art can replace the beads 130 on the surface of the rotating end surface 110 with surface structures such as sunburn patterns that can play a certain light scattering effect.
[0052] In the present embodiment, the convex lens 115 is arranged at the incident port 111 to condense the light source light directly incident into the lens, thereby improving the brightness of the center of the main light emitting part 112. Further, a light emitting port 116 can be arranged at the center position of the main light emitting part 112, and another convex lens 115 is arranged at the light emitting port 116 to further condense the light reflected by the convex lens 115 at the incident port 111. The arrangement of the convex lens 115 makes the light spot control more accurate, and the light spot angle can be controlled to be between 10° and 30° during condensation.
