Description

Technical Field

[0001] The utility model relates to the technical field of photography and videography, and particularly relates to a lighting fixture. Background Art

[0002] During photography and videography, since photographic lights emit light evenly and have a good soft light effect, they are particularly suitable for portrait photography, so they have always been favored by many photographers.

[0003] Common photographic light fixtures include a lamp body and a light source connected to the lamp body. By setting the light-emitting end of the light source at the light-incident surface of the lamp body, the light emitted by the light source enters the lamp body through the light-incident surface and is emitted through the light-emitting surface provided on the inner wall of the lamp body.

[0004] However, since the distances from the light source in the axial direction of the lamp body are inconsistent, the light-emitting brightness at the end of the light-emitting surface far from the light source is lower than that at the end close to the light source, resulting in poor overall light-emitting uniformity. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the technical problem of poor light-emitting uniformity of the lighting fixture.

[0006] To solve the above technical problem, the utility model provides a lighting fixture, including:

[0007] A lamp body, which is hollow inside and has a cavity. A light-emitting surface and a light-incident surface for transmitting light are provided on the inner wall of the lamp body, and the light-emitting surface is located on one side of the light-incident surface;

[0008] A light source, which is arranged on the lamp body, and the light-emitting end of the light source faces the light-incident surface;

[0009] A polarizing member, which is arranged between the light-emitting end of the light source and the light-incident surface. The light emitted by the light source is first subjected to polarization processing by the polarizing member, and then enters the cavity through the light-incident surface. The light entering the cavity is emitted from the light-emitting surface. The polarizing member is used to make the light passing through it shoot towards the light-incident surface in a set direction, and the set direction has an included angle with the normal direction of the light-incident surface.

[0010] In an exemplary embodiment of the present disclosure, the lamp body is a flexible member, the cavity can be inflated and forms a columnar structure after inflation. The light-emitting surface is arranged on the inner peripheral wall of the lamp body, the light-incident surface is arranged on the end wall of the lamp body, and a first reflecting surface is further arranged on the inner peripheral wall of the lamp body. Part of the light entering the cavity is reflected by the first reflecting surface and then emitted from the light-emitting surface.

[0011] In an exemplary embodiment of the present disclosure, the polarizing member is a Fresnel lens, which has an opposite first light surface and a textured surface. The first light surface of the Fresnel lens is disposed opposite to the light-emitting end of the light source, the textured surface of the Fresnel lens is disposed opposite to the light-incident surface, and the focal center of the textured surface of the Fresnel lens is eccentrically arranged.

[0012] In an exemplary embodiment of the present disclosure, the focal center of the textured surface of the Fresnel lens is located on a side of the central axis of the lamp body away from the light-emitting surface.

[0013] In an exemplary embodiment of the present disclosure, the polarizing member is a polarizing lens, which has an opposite second light surface and a microstructure surface. The second light surface of the polarizing lens is disposed opposite to the light-emitting end of the light source, and the microstructure surface of the polarizing lens is disposed opposite to the light-incident surface.

[0014] In an exemplary embodiment of the present disclosure, the microstructure surface includes a plurality of serrated units connected in sequence. The serrated unit includes a first plane perpendicular to the second light surface and a second plane inclined with respect to the second light surface. One end of the second plane facing away from the second light surface is connected to one end of the first plane facing away from the second light surface, and one end of the second plane far from the second light surface is closer to the light-emitting surface than one end of the second plane close to the second light surface.

[0015] In an exemplary embodiment of the present disclosure, the lamp body includes a main body portion and a mounting portion. The main body portion is a flexible member and forms a columnar structure after being inflated. One end face of the main body portion constitutes the light-incident surface; the mounting portion is annular, and the mounting portion is connected to the end periphery of the main body portion where the light-incident surface is formed, and the light-emitting end of the light source and the polarizing member are mounted in the mounting portion.

[0019] As can be seen from the above technical solutions, the beneficial effects of the present utility model are:

[0020] In the present application, by installing a polarizing member between the light-emitting end of the light source and the light-incident surface, the original parallel light-emitting mode of the light can be changed. Under the action of the polarizing member, the irradiation path of the light can be changed, so that the light is projected onto the inner wall of the cavity at a certain inclination angle. In this way, more light can be directed to the end of the light-emitting surface away from the light source, making the light more evenly dispersed, and thus obtaining a more uniform light-emitting effect.

If the descriptions of the positions of these elements change, the indications of these directions also change accordingly.

[0035] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0036] See also Figures 1 to 2 The present embodiment provides a lamp, which includes a lamp body 1, a light source 2 and a polarizer. The lamp body 1 is the main structure of the lamp, and the interior of the lamp body 1 is hollow and has a cavity. The lamp body 1 is a flexible member, and the cavity can be inflated. An inflating port 17 connected to the cavity can be provided on the lamp body 1, and air can be inflated into the cavity through the inflating port 17 to expand the lamp body 1 into shape.

[0037] It is understandable that an inflation valve can be provided at the inflation port 17 to open and close the inflation port 17 through the inflation valve. When the lamp body 1 is not needed, the inflation port 17 can be opened through the inflation valve to discharge the gas in the cavity to facilitate folding and storage of the lamp.

[0038] In some embodiments, an inner wall of the lamp body 1 is provided with a light-emitting surface 16 and a light-incident surface 15 for transmitting light. The light-incident surface 15 is located on one side of the light-emitting surface 16. Light is received at the light-incident surface 15, enters the cavity through the light-incident surface 15, and then exits from the light-emitting surface 16, thereby achieving illumination.

[0039] In some embodiments, after being inflated, the lamp body 1 forms a columnar structure, such that the lamp is an air column lamp. The light-incident surface 15 is disposed on an end wall of the lamp body 1, and the light-emitting surface 16 is disposed on an inner peripheral wall of the lamp body 1. In a direction along an axis of the lamp body, the light-emitting surface 16 is located on one side of the light-incident surface 15.

[0040] In some embodiments, a first light-reflecting surface 13 for reflecting light is further provided on an inner peripheral wall of the lamp body 1. After the light enters the cavity, it is reflected by the first light-reflecting surface 13 and exits from the light-emitting surface 16. By providing the first light-reflecting surface 13, the light entering the cavity can be reflected from different regions and converge on the light-emitting surface 16, thereby enhancing the intensity of the light exiting from the light-emitting surface 16.

[0041] In some embodiments, the light source 2 is disposed on the lamp body 1, and an outgoing end of the light source 2 faces the light-incident surface 15. Light emitted by the light source 2 enters the cavity through the light-incident surface 15. It can be understood that the light source 2 and the lamp body 1 are detachably connected, so that when illumination is not required, the light source 2 can be separately removed, thereby facilitating folding and storing the lamp body 1.

[0042] In some embodiments, the lamp body 1 may include a main body portion 11. The main body portion 11 is a main structure of the lamp body 1. The inside of the main body portion 11 is hollow to form the above-mentioned cavity, and an air inlet 17 is disposed on the main body portion 11. The main body portion 11 is a flexible member made of a flexible material, and forms a columnar structure after being inflated, such as a square columnar structure, a triangular columnar structure, a circular columnar structure, etc. It can be understood that the main body portion 11 being a columnar structure means that its cavity is inflated to form a columnar structure. In this embodiment, the main body portion 11 is taken as an example of a cylindrical structure for illustration.

[0043] In some embodiments, one end face of the main body portion 11 constitutes the above-mentioned light-incident surface 15, and the light-emitting surface 16 may be disposed on a circumferential side surface of the main body portion 11. In this way, the area of the light-emitting surface 16 of the light-emitting surface 16 can be set larger, and the irradiation range is larger. Among them, the first light-reflecting surface 13 is disposed on the circumferential side surface of the main body portion 11.

[0044] In some embodiments, the lamp body 1 further includes a soft light cloth for softening light. The soft light cloth is disposed on the light-emitting surface 16 to make the light exiting from the light-emitting surface 16 softer.

[0045] In some embodiments, the light-emitting surface 16 may not be provided with a soft light cloth, and the light-emitting surface 16 may also be an ordinary light-transmitting surface. A light-concentrating material may be provided on the light-emitting surface 16, which can be designed according to different needs.

[0046] In some embodiments, a second reflecting surface 14 is provided on the inner peripheral wall at the other end of the main body portion 11. The second reflecting surface 14 and the light-incident surface 15 are oppositely arranged. Part of the light entering the cavity is reflected by the first reflecting surface 13 to the second reflecting surface 14, and then reflected from the second reflecting surface 14 to the light-emitting surface 16 and emitted. Part of the light can also be directly reflected by the second reflecting surface 14 to the light-emitting surface 16. By providing the second reflecting surface 14 in cooperation with the first reflecting surface 13, the light can be reflected multiple times to the light-emitting surface 16 after entering the cavity, so as to increase the light intensity of the light-emitting surface 16.

[0047] In some embodiments, the second reflecting surface 14 is not light-transmitting to prevent light from directly passing through the second reflecting surface 14 after entering the cavity from the light-incident surface 15. The second reflecting surface 14 and the light-incident surface 15 can completely cover the end faces at both ends of the main body portion 11, or only part of the end face of the main body portion 11 forms the second reflecting surface 14 and the light-incident surface 15. When the light-incident surface 15 and the second reflecting surface 14 respectively completely cover one end face of the main body portion 11, more light can enter, the reflection effect of the second reflecting surface 14 is stronger, and finally more light is emitted from the light-emitting surface 16.

[0048] In some embodiments, a light-transmitting area and a non-light-transmitting area are provided on the inner peripheral wall of the main body portion 11. The light-transmitting area can allow light to pass through, so the light-transmitting area can form the above-mentioned light-emitting surface 16. The non-light-transmitting area cannot allow light to pass through, and the non-light-transmitting area can form the above-mentioned first reflecting surface 13. The light entering the cavity is reflected by the first reflecting surface 13 to the light-emitting surface 16. In cooperation with the reflection of light by the second reflecting surface 14, the light entering the cavity can be reflected to the light-emitting surface 16 from various angles.

[0049] In some embodiments, a diffuse reflection member may be provided on the first reflecting surface 13 and the second reflecting surface 14 to reflect light. The diffuse reflection member can be an optically silver-plated matte particle, so that the first reflecting surface 13 and the second reflecting surface 14 have a high-efficiency reflection effect. In addition to providing optically silver-plated matte particles on the first reflecting surface 13 and the second reflecting surface 14, the first reflecting surface 13 and the second reflecting surface 14 can also be subjected to a matte treatment to have a high reflection or diffuse reflection effect.

[0050] In some embodiments, the lamp body 1 further includes a mounting portion 12. The mounting portion 12 is annular, and the mounting portion 12 is connected to the end peripheral edge of one end of the main body portion 11 that forms the light incident surface 15. When installing the light source 2, the light emitting end of the light source 2 is installed in the mounting portion 12. By locking the mounting portion 12, the light source 2 and the lamp body 1 can be fixedly connected as a whole. The mounting portion 12 plays a role in shielding the light emitting end of the light source 2, preventing the light emitted by the light source 2 from leaking before entering the cavity.

[0051] In some embodiments, the mounting portion 12 can be integrally formed with the main body portion 11, and the mounting portion 12 is formed by extending from the outer peripheral side surface of the main body portion 11 along the axial direction of the main body portion 11 to the outside of the light incident surface 15. The mounting portion 12 can also be an independent component from the main body portion 11, and the mounting portion 12 is connected to the end of the main body portion 11 by means of clamping, screwing, or bonding.

[0052] See Figure 3 , in some embodiments, since the shapes and styles of the light sources 2 may be different, in order to be able to adapt to different light sources 2, the lamp further includes a lamp retaining ring 3 and an adapter ring 4. The lamp retaining ring 3 can be adaptively connected to the light source 2, the light emitting end of the light source 2 is clamped in the lamp retaining ring 3, the lamp retaining ring 3 is connected to the adapter ring 4, and the adapter ring 4 is connected to the mounting portion 12, so that different light sources 2 can be connected through their adapted lamp retaining rings 3 and adapter rings 4, and then connected to the lamp body 1.

[0053] It can be understood that different light sources 2 can be configured with corresponding lamp retaining rings 3. The lamp retaining ring 3 includes a first ring portion 31 for connecting to the adapter ring 4 and a second ring portion 32 for connecting to the light source 2. An annular groove 33 is provided on the outer peripheral wall of the first ring portion 31, and the first ring portion 31 is clamped in the adapter ring 4. The adapter ring 4 is provided with a buckle that can be engaged in the annular groove 33, so that the lamp retaining ring 3 can be connected to the adapter ring 4.

[0054] In this embodiment, the light emitting end of the light source 2 is provided with a protruding circumferential wall, and the second ring portion 32 of the lamp retaining ring 3 is clamped on the circumferential wall. A plurality of block structures are provided on the second ring portion 32 to be engaged with the block structures inside the circumferential wall.

[0055] In some embodiments, the outer diameter of the adapter ring 4 can be matched with the inner diameter of the mounting portion 12, and the two can be in interference fit to clamp the adapter ring 4. The two can also be in clearance fit to facilitate the adapter ring 4 to be inserted into the mounting portion 12 and be clamped by other means.

[0056] In some embodiments, the lamp can further include a locking member 6. The locking member 6 can be a clamp, and the clamp is sleeved on the outer peripheral wall of the mounting portion 12 to clamp the mounting portion 12, so that the adapter ring 4 and the mounting portion 12 are locked and fixed. The locking member 6 can also be a locking strap to tie the mounting portion 12 and the adapter portion tightly.

[0057] In some embodiments, a magnetic component is further provided on the end face of the lamp holder snap ring 3 away from the light source 2, and a magnetic accessory is adsorbed on the magnetic component. The magnetic accessory and the lamp holder snap ring 3 are coaxially arranged. The magnetic accessory can be a filter 5 to filter the light emitted from the light source 2 into the lamp body 1, so as to form light of different colors. Among them, the magnetic component can be a magnetic iron ring, which is arranged on the end face of the lamp holder snap ring 3 away from the light source 2, and the magnetic accessory is magnetically adsorbed on the magnetic iron ring. Multiple magnetic accessories can be provided, and the multiple magnetic accessories are sequentially arranged along the axial direction of the lamp holder snap ring 3.

[0058] Continue to refer to Figures 3 to 10 , in some embodiments, the polarizer is arranged between the light-emitting end of the light source 2 and the light-incident surface 15. The light emitted by the light source 2 is first subjected to polarization processing by the polarizer, and then enters the cavity through the light-incident surface 15, and the light entering the cavity is emitted from the light-emitting surface 16. Among them, the polarizer is used to make the light passing through it irradiate the light-incident surface 15 along the set direction S. The set direction S has an included angle with the normal direction of the light-incident surface 15, so that the light passing through the polarizer changes its original parallel light-emitting mode, and a part of the light can be projected onto the inner wall of the cavity at an inclined angle, so that more light can be directly guided to one end of the light-emitting surface 16 away from the light-incident surface 15. Further, part of the light can also be reflected by the first reflecting surface 13 to the one end of the light-emitting surface 16 away from the light-incident surface 15, so that the light-emitting surface 16 obtains a more uniform light-emitting distribution.

[0059] It can be understood that the set direction S has an included angle with the normal direction of the light-incident surface 15, which means that the set direction S is not perpendicular to the plane where the light-incident surface 15 is located. After the light enters the cavity from the light-incident surface 15, the light has an included angle with the axis direction of the lamp body 1, the set direction S is not parallel to the axis direction of the lamp body 1, the set direction S can be offset toward the side away from the light-emitting surface 16 to guide more light to directly irradiate the first reflecting surface 13, and make more of it reach the one end of the light-emitting surface 16 away from the light-incident surface 15 through the reflection of the first reflecting surface 13. The set direction S can also be inclined toward the light-emitting surface 16 to guide more light to directly irradiate the one end of the light-emitting surface 16 away from the light-incident surface 15.

[0060] In some embodiments, the polarizer can be connected to the light-emitting end of the light source 2 or to the lamp body 1. In this embodiment, the polarizer is arranged in the mounting portion 12 and is located between the adapter ring 4 and the light-incident surface 15, so as to be able to cover all the light emitted from the adapter ring 4 and make all the light emitted from the light source 2 pass through the polarization processing of the polarizer.

[0061] Refer to Figures 4 to 6, in some embodiments, the polarizing member is a Fresnel lens 7. The Fresnel lens 7 is a thin sheet injection-molded from a polyolefin material, which can change the path of the passing light. It can be understood that the Fresnel lens 7 has opposite first light surface 71 and textured surface 72, and a plurality of concentric circular patterns 74 from small to large are engraved on the textured surface 72. During installation, the first light surface 71 of the Fresnel lens 7 is arranged opposite to the light-emitting end of the light source 2, and the textured surface 72 of the Fresnel lens 7 is arranged opposite to the light-incident surface 15. When the light passes through the Fresnel lens 7, it enters from the first light surface 71 and then exits from the textured surface 72. The principle of the Fresnel lens 7 causing the light to shift will not be elaborated here.

[0062] In this embodiment, the focal center 73 of the textured surface 72 of the Fresnel lens 7 is eccentrically arranged, so that when the light exits from the textured surface 72, the optical path is shifted to intersect with the axis direction of the lamp body 1. It can be understood that the focal center 73 of the textured surface 72 of the Fresnel lens 7 refers to the common center of the plurality of concentric circular patterns 74 on the textured surface 72, and its eccentric arrangement means that the common center is offset relative to the physical center of the textured surface 72.

[0063] See Figure 4 , in some embodiments, the focal center 73 of the textured surface 72 of the Fresnel lens 7 is located on the side of the central axis of the lamp body 1 away from the light-emitting surface 16, so that after exiting from the textured surface 72, the light is obliquely emitted in the set direction S away from the light-emitting surface 16 and shoots towards a part of the first reflecting surface 13 opposite to the light-emitting surface 16, and then is reflected by this part of the first reflecting surface 13 to shoot towards one end of the light-emitting surface 16 away from the light-incident surface 15, guiding more light to reach one end of the light-emitting surface 16 away from the light-incident surface 15, so that the light-emitting surface 16 obtains a more uniform light-emitting distribution.

[0064] It can be understood that when the Fresnel lens 7 is rotated, the direction of the light after exiting from the textured surface 72 of the Fresnel lens 7 also changes accordingly. For example, when the focal center 73 of the textured surface 72 of the Fresnel lens 7 is located on the side of the central axis of the lamp body 1 close to the light-emitting surface 16, the set direction S can be inclined towards the light-emitting surface 16.

[0065] See Figures 7 to 10 , in some embodiments, the polarizing member can also be a polarizing lens 8. The polarizing lens 8 can change the path of the light passing through it. The polarizing lens 8 has opposite second light surface 81 and microstructured surface 82. During installation, the second light surface 81 of the polarizing lens 8 is arranged opposite to the light-emitting end of the light source 2, and the microstructured surface 82 of the polarizing lens 8 and the light-incident surface 15 are arranged opposite. When the light passes through the polarizing lens 8, it enters from the second light surface 81 and then exits from the microstructured surface 82, and the path of the light exiting is changed through the microstructured surface 82 so that the light enters the cavity along the set direction S. The principle of the polarizing lens 8 causing the light to shift will not be elaborated here.

[0066] In some embodiments, the microstructured surface 82 includes a plurality of serrated units 83 connected in sequence. The serrated unit 83 includes a first plane 831 perpendicular to the second light surface 81 and a second plane 832 inclined with respect to the second light surface 81. One end of the second plane 832 facing away from the second light surface 81 is connected to one end of the first plane 831 facing away from the second light surface 81, and the connection forms the tooth portion of the serrated unit 83. By forming a plurality of serrated units 83, the light passing through the microstructured surface 82 undergoes a path shift and intersects with the axial direction of the lamp body 1.

[0067] See Figure 8 , in the present embodiment, one end of the second plane 832 far from the second light surface 81 is closer to the light-emitting surface 16 than one end of the second plane 832 close to the second light surface 81, so that the light emitted from the second plane 832 is inclined and emitted in the set direction S away from the light-emitting surface 16, so as to guide more light to a part of the first reflecting surface 13 facing the light-emitting surface 16, and then through the reflection of the first reflecting surface 13 to one end of the light-emitting surface 16 away from the light-incident surface 15, so that the light-emitting surface 16 obtains a more uniform light-emitting distribution.

[0068] In some embodiments, the microstructured surface 82 may further include a plurality of wedge-shaped or curved surface structures to achieve polarization processing.

[0069] In some embodiments, the lamp body 1 may also be in other shapes, such as an ellipsoid, a sphere or an umbrella-shaped lamp. The lamp body may also be made of a non-flexible material. The lamp body 1 is made of a hard material, and its cavity is non-inflatable and always maintains the same shape and cannot be folded. Among them, the light-transmitting area of the lamp body 1 can be made of materials such as acrylic, polyethylene or polyvinyl chloride to have light-transmitting properties.

[0070] In some embodiments, the inner wall of the lamp body 1 may be completely covered with a light-transmitting area, so that the part of the inner wall of the lamp body 1 except the light-incident surface is the light-emitting surface.

[0071] In summary, in the present embodiment, by providing a polarizing member between the light-emitting end of the light source 2 and the light-incident surface 15, the light passing through it is deflected, and the light can be projected onto the inner wall of the cavity at a certain inclination angle. More light can be guided to one end of the light-emitting surface 16 away from the light source 2 through the first reflecting surface 13, and part of the light will directly shoot towards one end of the light-emitting surface 16 away from the light source 2, so as to obtain a more uniform light-emitting effect and improve the illumination effect of the lamp body 1.

[0072] While the present utility model has been described with reference to several exemplary embodiments, it should be understood that the terms used are illustrative and exemplary, rather than restrictive. Since the present utility model can be embodied in many forms without departing from the spirit or essence of the utility model, it should be understood that the above-described embodiments are not limited to any of the foregoing details, but should be construed broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
