Description

Photographic lamp

Technical Field

The invention relates to the field of photographic equipment, in particular to a photographic lamp which can flexibly change the shape of the lamp and adapt to different illumination requirements of different photographic occasions.

Background

In the use of photography and image capturing, the lamplight has a significant role in photography or image capturing effect. That is, the use of light has a multiplicative effect for photography or image capturing. Particularly, in recent years, due to the rising of various industries such as photography, image pickup, entertainment, live broadcast and the like, the light effect has a great influence on the quality of the photographic module. It should be noted that, for the use environment of photography or image capturing, indoor or outdoor photography is often selected according to the requirement, and the external ambient light captured at these places usually does not reach the optimal effect during the photography, so that a general photographer, a photographer or related personnel can use a lamp or a light supplementing lamp to provide the light source which is deficient during the photography, so as to improve the photography effect.

As a solution, in chinese patent publication CN207301581, a light-compensating lamp group with a main photographing lamp in the middle and sub photographing lamps at both sides thereof in a pivot connection manner is proposed to provide a large-range light-compensating light, so that the light-compensating lamp group can perform omnidirectional light-compensating on a person to be photographed to effectively improve the illuminance of a face or a whole body and improve the quality of a photographed image. Because the lamp for secondary photography can be rotationally adjusted according to the position of the object to be photographed, each position of the object to be photographed is effectively ensured to be subjected to auxiliary light, and the quality of the photographed image is further effectively improved. However, such a large-area light-supplementing lamp set still has the following disadvantages: 1. the combined light supplementing lamp set has large volume and heavy weight, is generally only fixed on the front or back of a shot person by virtue of a stay bar, has high space requirements on shooting sites, is difficult to flexibly switch among a plurality of different shooting sites, and has low practicability; 2. the combined light supplementing lamp group projects light rays from the face in the front direction of the face to improve the illuminance, so that the illuminance of the whole face is consistent, which is unexpected for a photographer when shooting certain side photos, for example, the function is single, and the random creating requirement of an author cannot be well met; 3. the combined lamp has high acquisition cost and is not easy to store; 4. the man-machine interaction is poor and the intelligence is not enough.

As a further improvement, a collapsible portable flag frame and a light supplementing luminaire and application thereof are disclosed in chinese patent application publication CN108895357a, wherein a light supplementing plate 30 is detachably mounted to a collapsible portable flag frame 10. Thus, the light supplementing panel 30 will be directly disposable to the collapsible portable flag frame 10 when the collapsible portable flag frame 10 is in the expanded support configuration. Wherein the two second frames of the collapsible portable flag frame 10 are capable of twisting relative to the first frame such that the collapsible portable flag frame 10 is in an expanded support configuration or a collapsed storage configuration. To achieve different illumination intensities, the light compensating plate 30 may be implemented as a white light plate, a silver light plate, a gold light plate, a black light plate, and a soft light curtain plate, so as to provide strong light with different illumination intensities, soft light or light with different cooling and warming hues, and the light compensating plate is used for shooting on articles to have a sense of texture.

However, such collapsible portable flag frames and light supplementing fixtures still suffer from the following disadvantages: 1. the combined flag frame and the light supplementing lamp are still large in size and heavy in weight, and generally need to be carried and used by special persons, so that the practicability is not strong; 2. the combined flag frame and the light supplementing lamp also project light from the face in the front direction of the face to improve the illuminance, so that the illuminance of the whole face is consistent, which is undesirable for a photographer when shooting certain side photos, for example, the combined flag frame and the light supplementing lamp have single function and cannot well meet the random creation requirement of an author; 3. the purchase cost is high and the storage are not easy.

The above variety can reduce the use experience of the user on the combined type light supplementing lamp, thereby influencing the motivation and the desire of the user to purchase the light supplementing lamp.

Based on this, the related art is strive to design a photographic lamp to overcome the drawbacks of the prior art.

Detailed Description

An exemplary embodiment of a photographic lamp according to the present invention will now be described in detail with reference to the accompanying drawings. The drawings are provided to present various embodiments of the invention, but are not necessarily drawn to scale and certain features may be exaggerated, removed, or partially sectioned to better illustrate and explain the present disclosure. The position of part of components in the drawings can be adjusted according to actual requirements on the premise of not affecting the technical effect. The appearances of the phrase "in the drawings" or similar language in the specification do not necessarily all refer to the figures or examples.

Certain directional terms used hereinafter to describe the drawings, such as "inner", "outer", "upper", "lower", "top", "bottom" and other directional terms, will be understood to have their normal meaning and refer to those directions as they would be when viewing the drawings. Unless otherwise indicated, directional terms described in this specification are essentially in accordance with conventional directions as understood by those skilled in the art.

The terms "first," "second," "primary," "secondary," and the like as used herein do not denote any order, quantity, or importance, but rather are used to distinguish one element from another. Wherein the expression "substantially parallel" allows a reasonable range of angular deviations to exist, without being absolutely parallel to each other.

Some embodiments of the present application are described in detail below with reference to the accompanying drawings. The following embodiments and features of the embodiments may be combined with each other without conflict.

First, a first embodiment of the present application will be exemplarily described with reference to fig. 1 to 7 and 10A to B, and referring to fig. 1, a photographic lamp 10 according to the present application includes a main lamp holder 11A, preferably three sub lamp holders 11B, 11C and 11D therein, which are sequentially connected, and a first pivoting member 13 connected with the sub lamp holders 11B and 11C, respectively. A lamp strip 12 is provided on the main lamp frame 11A, preferably on the top surface; a light strip 12 is also provided on the top surface of the three sub-lamp holders 11B, 11C and 11D connected in sequence. To facilitate heat dissipation, aluminum plates are preferably provided between the light strip 12 and the lamp fixture to facilitate heat transfer or dissipation. The first pivot member 13 here enables the secondary lamp frame 11B and the secondary lamp holder 11C to pivot relative to each other about two different axes. Further, as is preferable, a second pivoting member 14 connected to the lamp holders at both ends thereof, respectively, is also provided between the main lamp holder 11A and the sub-lamp holder 11B and between the sub-lamp holder 11C and the sub-lamp holder 11D to allow the two lamp holders connected thereto to pivot with each other about one axis.

Thereby, a pivoting movement diagram as shown in fig. 2 is achieved, wherein the photographic light fixture 10 is now in a soft light configuration. In this soft light form, by means of the first pivoting member 13 pivotable about two different axes with respect to each other, adjustment of the illuminance of the soft and hard light of the picture of the photographic subject can be achieved by adjusting the angle (or the brightness of the light, etc.) between the different light beams emitted by the light bands on the different lamp holders. In particular, wherein one pivot axis of the first pivot member 13 is the light strip 12 which is designed to be perpendicular to the main light frame 11A (here, perpendicular to the paper surface direction), it is thereby ensured that in the folded configuration shown in fig. 1, the light strip 12 of the main light frame 11A is parallel or in the same plane as the light strip 12 of the sub light frame, and that on the other hand, the opening angle between the sub light frame 11B and the sub light frame 11C connected to each other with the first pivot member 13 can also be adjusted, which opening angle can be adjusted, for example, between 0-180 degrees, allowing switching of the hard light configuration and the soft light configuration as between fig. 10A-10B, or even further adjustment of the illuminance in the soft light configuration. Still further, by means of the other, parallel or coplanar pivot axis (pivot direction as the swivel arrows on both sides of the first pivot member 13 in fig. 2) around the first pivot member 13 of the lamp strip 12 of the main lamp frame 11A and the lamp strip 12 of the sub-lamp frame, it is also allowed to adjust the pose of the different lamp strips 12 on both the sub-lamp frame 11B and the sub-lamp frame 11C by adjusting the pivot angle of the sub-lamp frame 11B with respect to the first pivot member 13 and the pivot angle of the sub-lamp frame 11C with respect to the first pivot member 13, so that the illuminance of the soft light form and/or the hard light form can be adjusted (see fig. 10A, 10B).

As another aspect of the present invention, second pivoting members 14 may be provided between the main and sub lamp frames 11A and 11B and the sub lamp frames 11C and 11D, wherein both ends of the second pivoting members 14 are connected to the main and sub lamp frames 11A and 11B, respectively, or both ends of the second pivoting members 14 may be connected to the two sub lamp frames 11C and 11D, respectively, to allow the two connected thereto to pivot with each other about one axis, thereby adjusting an opening angle between the lamp holders, thereby enabling more flexible adjustment of a use form composed of a plurality of lamp holders, and enabling reduction of the use of the more costly biaxial pivotable first pivoting members, thereby reducing the cost of the photographic lamp.

It is noted that although an embodiment is shown here in which a single primary lighting fixture 11A and three secondary lighting fixtures 11B-11D are connected using a single first pivot member 13 and two second pivot members 14 by way of example, one skilled in the art will appreciate that it is also possible to connect a single primary lighting fixture and a single or multiple secondary lighting fixtures (add a movable joint or multiple piece lighting fixtures) by means of a single first pivot member 13. The arrangement of the first and second pivoting members and the sub-lamp frame is flexible and variable, which may be appropriately designed according to the use form of the lamp, the cost of the product, etc., and thus the present invention is not intended to be limited to the arrangement shown in fig. 1-3.

As shown in fig. 1, the main lamp frame 11A and the plurality of sub lamp frames 11B to 11D in the photographic lamp provided therein are preferably each designed in a rectangular parallelepiped shape having substantially the same shape and size. Wherein, unlike the auxiliary lamp holders 11B-11D, the main lamp holder 11A is convexly provided with a hand-holding part 16 for holding the photographic lamp by a user on one side of the lamp strip 12, for example, the hand-holding part can be formed by texturing or roughening one side of the main lamp holder 11A so as to facilitate the holding by the user, and further, by means of the space formed by the convex protrusion, the electric parts of the photographic lamp 10 including the control device or the bluetooth module can be arranged therein. Further, a display screen 15 is disposed adjacent to the hand-held portion at the bottom of the main lamp housing 11A, wherein the display screen 15 is designed to display information including illuminance, lamp power.

Here, as shown in fig. 2 and 3, the light-emitting surfaces of the main lamp holders 11A and the lamp strips 12 are in the same plane as the light-emitting surfaces of the lamp strips 12 of the at least one sub-lamp holder 11B-11D, wherein one pivot axis of the first pivot member 13 and/or the pivot axis of the second pivot member 14 are perpendicular to the light-emitting surfaces of the lamp strips 12 of the lamp holders. By designing the light emitting directions of the main lamp holders 11A and the lamp strips 12 of at least one sub lamp holder 11B-11D to be identical, and the pivot axis of the first pivot member 13 and/or the pivot axis of the second pivot member 14 to be perpendicular to the light emitting surface of the lamp strip 12, the overall lighting direction of the photographic lamp 10 is not affected regardless of how the sub lamp holders 11B-11D rotate relative to the main lamp holder 11A, and a complete lighting is formed to ensure the lighting effect. This substantially eliminates or avoids the risk of undesired lighting sloshing during user operation. Of course, it is preferable to make the light emitting surfaces of the lamp holders 11A and the lamp strips 12 and the light emitting surfaces of the lamp strips 12 of at least one sub-lamp holder 11B-11D be in the same plane, but not limited thereto, and those skilled in the art will understand that, in a possible modification, the lamp strips 12 of the main lamp holder 11A and the lamp strips of the plurality of sub-lamp holders 11B-11D may be designed to be parallel to each other but offset to form a staggered illumination.

By means of the above design, by providing a main lamp frame 11A with a lamp band 12 and at least one sub lamp frame 11B-11D also with a lamp band 12, which are rotatably connected by means of the first pivot member 13 and/or the second pivot member 14, these sub lamp frames 11B-11D are switched from the main lamp frame 11A in a number of different use configurations by rotating the first pivot member 13 and/or the second pivot member 14. For example, as shown in fig. 3, the plurality of sub-lamp holders 11B to 11D and the main lamp holder 11A are connected to each other by means of the first pivot member 13 and/or the second pivot member 14 in a line-shaped manner, and the lamp band 12 of the main lamp holder 11A and the lamp band 12 of the plurality of sub-lamp holders 11B to 11D are formed as a line light source suitable for photographing, for example, a side face of a person (see fig. 3 and 10A), and the photographing lamp 10 is in its hard light form, in which a light shadow is hard, and a vivid contrast of the face of the person can be provided, in which form the length of the multifunctional lamp holder 10 is increased but the width is reduced; or the plurality of auxiliary lamp holders 11B-11D and the main lamp holder 11A are folded together in the length direction to be in the folded configuration of the photographic lamp 10, at this time, the plurality of lamp bands 12 are folded together to form a surface, that is, the lamp bands 12 of the main lamp holder 11A and the lamp bands 12 of the plurality of auxiliary lamp holders 11B-11D are formed together to be, for example, a surface light source suitable for direct seeding light supplement for a seeding host at the front (see fig. 1), in which configuration the length of the multifunctional lamp holder 10 is reduced but the width is doubled; or the main lamp holder 11A and the auxiliary lamp holder 11B are connected in a linear manner, and the auxiliary lamp holders 11C and 11D are also connected in a linear manner, and a V-shape is formed between the auxiliary lamp holders 11B and 11C, at this time, the lamp bands 12 carried by the main lamp holder 11A and the auxiliary lamp holder 11B and the lamp bands 12 carried by the auxiliary lamp holders 11C and 11D are formed as V-shaped light sources between each other so as to be suitable for providing soft light forms (see fig. 2 and 10B) with softer light shadows and strong stereoscopic impression, and especially at this time, the lamp holders respectively formed in a linear manner can also adjust the positions of the lamp bands on different lamp holders by means of the revolving of the second pivot axis around the first pivot member 13, so that the illuminance of the soft light forms and/or the hard light forms can be adjusted. As can be seen from the above, these configurations significantly enrich the usage pattern of the photographic lamp 10 in the present invention, and can flexibly change the irradiation directions of the lamp strips on different lamp holders while expanding and enriching the usage scene of the photographic lamp 10.

Specifically, in the present embodiment, as shown in fig. 6 and 7, the first pivoting member 13 includes paired pivoting covers 31 and 32 stacked on each other, where the upper-located pivoting cover 31 is designed to be substantially disc-shaped and provided at one end thereof tangentially with a tip through which an electric wire (not shown) passes, and the lower-located pivoting cover 32 is also designed to be substantially complementary to the pivoting cover 31 and provided at the opposite end thereof tangentially with a tip through which an electric wire passes, such design allowing the paired pivoting covers 31 and 32 to pivot with each other about the first pivoting axis A1 and provided at the periphery thereof with a cavity through which an electric wire (not shown) passes; a pair of swivel joints 35 provided at the two opposite ends, wherein the pair of swivel joints 35 are pivotally connected to the ends of the opposite ends of the pair of swivel covers 31 and 32, respectively, about a second pivot axis A2, preferably parallel or even aligned with each other, with connecting fasteners for fixedly connecting to different lamp holders (here, the sub-lamp holder 11B and the sub-lamp holder 11C), thereby allowing the sub-lamp holders 11B and 11C to which they are connected to pivot with each other about the second pivot axis A2. Thereby, allowing the electric wire to pass through the two first pivoting members 13 pivotable in two directions with respect to each other in a stealth arrangement not only can protect the electric wire from abrasion or external moisture and dust, but also can keep the external appearance of the photographic lamp 10 neat and beautiful.

In order to achieve rotational positioning of the first pivot member 13, a plurality of elastic members 34 are preferably provided between the pair of shaft covers 31 and 32. As shown in fig. 6, a pair of elastic members 34 are interposed between the upper and lower spin covers 31 and 32 and the lower spin cover 32 and the locking member 33 by means of a locking member 33 such as a lock nut with a spin shaft 33A described in detail below, whereby if it is desired to achieve locking of the first pivoting member 13 to adjust the force driving the pivoting thereof or the damping effect of the self-contained, these elastic members 34 can be driven to act between a damping position of abutting against the spin cover and a releasing position of releasing the abutting against via rotation of the locking member 33 itself by screwing or unscrewing the locking member 33, thereby achieving rotational positioning of the first pivoting member 13 at low cost and in a convenient manner for the user. Similarly, the pairs of adapters 35 for fixed connection with the sub-lamp frames 11B and 11C may also be connected to the ends of the spindle covers 31 and 32 in a tightness-adjustable manner by means of elastic members 36 and 37, wherein the damping effect of the pairs of adapters 35 is adjusted by means of adjusting the tightness of the mounting members.

Of course, in other embodiments, the first pivot member 13 may be a biaxial pivot seat or a hinge (the structure and working principle of the pivot seat and hinge used as the rotating member are all the prior art, and are not specifically labeled in the drawings). As a preferred aspect, magnetic members are provided at opposite sides between the sub-lamp frame 11B and the sub-lamp frame 11C, and poles of opposite sides in the opposite magnetic members are different, so that the sub-lamp frame 11B and the sub-lamp frame 11C can be magnetically connected with each other by the magnetic members. When the auxiliary lamp frame 11B rotates to be mutually attached to the side surface of the auxiliary lamp frame 11C, the magnetic piece between the auxiliary lamp frame 11B and the auxiliary lamp frame can fix the auxiliary lamp frame 11C on the auxiliary lamp frame 11B, so that the auxiliary lamp frame 11C is prevented from shaking, and the stability of the photographic lamp 10 in a hard light state is improved.

Referring to fig. 4 and 5, a second pivot member 14 according to the invention is shown, wherein preferably a plurality of second pivot members 14 are identical, and are therefore exemplarily shown by means of fig. 4-5. Wherein the second pivot member 14 comprises: the first adapter block 41 and the second adapter block 42 which can be fixedly connected to different lamp holders, wherein the opposite sides of the first adapter block 41 and the second adapter block 42 are respectively provided with a mounting surface for the fasteners to pass through and for the different lamp holders to be placed; first and second spaced apart electrode pads 44A and 44B (electrical wires connected thereto are not shown) respectively secured within first and second adapter blocks 41 and 42, wherein the two are at least partially stacked so as to enable electrical connection and signal transfer between first and second adapter blocks 41 and 42 by means of first and second electrode pads 44A and 44A; in order to avoid exposure of the first and second electrode sheets 44A and 44B to moisture and dust, a pair of shaft covers 43A are also provided which are superposed on each other, wherein the shaft covers located below are provided with a shaft 43B for defining a pivot axis, thereby allowing the first and second joint blocks 41 and 42 to be hinged to each other by means of the shaft 43B. Therefore, the angle adjustment and the electric connection between the lamp holders are realized in a manner of saving the number of parts, and the electric connection is realized by adopting the electrodes, so that the defect that the electric contact or the contact is worn and failed after being used for multiple times is avoided.

Of course, in other embodiments, the second pivot member 14 may be a single-axis pivot seat or a hinge (both the pivot seat and the hinge are used as rotating members and the working principle is not specifically shown in the drawings). As a preferable aspect, magnetic members are provided on opposite sides between the main lamp housing 11A and the sub-lamp housing 11B, and poles of opposite sides among the opposite magnetic members are different, so that the main lamp housing 11A and the sub-lamp housing 11B can be magnetically connected by the magnetic members. When the auxiliary lamp frame 11B rotates to be mutually attached to the side surface of the main lamp frame 11A, the magnetic piece between the auxiliary lamp frame 11B and the main lamp frame 11A can fix the auxiliary lamp frame 11B on the main lamp frame 11A, so that the auxiliary lamp frame 11B is prevented from shaking, and the stability of the photographic lamp 10 in a hard light state is improved.

As shown in fig. 10A, in which in a hard light form, since the outgoing light from the light strips 12 of the plurality of lamp holders is irradiated onto, for example, a human face, along only one side, since the light is on the same side of the irradiated person, the other side has a relatively large and hard shadow, which is suitable for photographing, for example, a face portrait with a strong contrast. In the soft light mode, as shown in fig. 10B, the light bands 12 from the plurality of lamp holders are simultaneously irradiated on the face of the irradiated person from one side and from the upper portion thereof, respectively, and at this time, the shadow on the irradiated person is relatively small and soft due to the convergence of different light rays, which is suitable for reflecting the bright and warm photographing intention. It is known to the person skilled in the art that two different effects each have their application range, and that it is attractive for a photographer to be able to realize different modalities in a single luminaire. Further preferably, each section of the collapsible photographic light fixture 10 may also display a different color, giving the photographer more room to create more colorful works.

A second embodiment of the present application is described below with reference to fig. 8-10A-B, which is a further modification of the first embodiment, and parts not specifically described include the same reference numerals and text descriptions as those of the first embodiment, and are not repeated here.

The main improvement of the second embodiment over the first embodiment is that in the second embodiment of the present application, as seen in connection with fig. 8, an operation button 26 arranged adjacent to the hand-held part is further added on one side of the light strip 12 of the photographic light fixture 20, wherein the operation button 26 is a physical or mechanically operated physical button, in this embodiment configured to adjust at least one of the color, the color temperature, and the instantaneous power output (preferably, for example, up to 50-100 watts) of the light strip of at least one of the main light fixture and the sub-light fixture; further, it also preferably has the effect of locking the touch screen 25 here in response to a long press, for example 2 seconds or a continuous double click, which helps to prevent the risk of incorrect operation during folding and transport of the photographic light fixture 20, for example in a pocket.

Here, a display screen 25 is also included, which is arranged adjacent to the handpiece, wherein the display screen 25 is preferably a touch screen which can accept user inputs. Wherein the touch screen 25 is designed to display information including illuminance, lamp power, and further to add a touch area to control color temperature and brightness. As an example, the middle region is to coarsely adjust color temperature and brightness in response to a user's finger sliding, while two small regions on both sides of the middle region are to be finely adjustable. Preferably, the luminaire 20 can also be preset in a plurality of smart modes and support custom modes by means of the touch screen. Meanwhile, the bluetooth module built in the lamp 20 allows a user to realize wireless connection by means of the APP of a remote controller or a mobile phone, so as to realize remote control.

Further, as shown in fig. 8 to 9, wherein in the present embodiment, in order to further reduce the cost of the lamp, a first pivot member 23 and a second pivot member 24 different in structure from the first embodiment are employed, and here, the pivot member located in the middle that performs the pivoting action in both directions is changed to the same member as the pivot member pivoted in a single direction. At this time, only the unidirectional pivoting piece is designed to be split and the pivoting shaft is additionally arranged in the middle of the unidirectional pivoting piece to realize bidirectional pivoting. Thereby, the photographic lamp is allowed to be manufactured in a standardized manner of a single kind of pivoting member, thereby avoiding the disadvantage of increasing kinds of parts and assembly difficulty due to the need to alternately mount different pivoting members.

In fig. 11, a unidirectional pivot member 24 that can be adapted for use in the embodiment of fig. 8-9 is schematically shown, wherein the pivot member 24 comprises a generally racetrack-shaped pivot mount 245, wherein arcuate cavities are cut out at opposite ends of the pivot mount 245 for pivoting a pivot shaft 243 described below and an adapter 243A fixedly connected thereto. The inner diameter of the arcuate cavity is designed here to be approximately the same as the rotational axis 243, so that it allows two rotational axes 243 and an adapter 243A fixedly connected thereto to be accommodated therein in a manner pivoting about the pivot axes A1a and A1b, respectively, in a clearance fit. Here, two adjacent adapters 243A are respectively connected to two lamp holders (see fig. 9), so that the angle between the two lamp holders connected thereto (for example, lamp holders 11C and 11D) is adjusted by means of the pivot shafts 243 and the adapters 243A fixedly connected thereto being pivoted about the pivot axes A1a and A1b, respectively. As shown in fig. 11, in this case, the middle of two adjacent adapters 243A is provided with a slot which allows the electrical wire 246 to pass through, and correspondingly, the two shafts 243 are provided with a slot which allows the middle section of the electrical wire 246 to pass through. In order to prevent the electric wire 246 from being exposed and external dust from entering into the narrow gap between the rotation shaft 243 and the pivot seat 245 to adversely affect the rotation of the rotation shaft 243, the rotation shaft cover 241 may be fixed to the pivot seat 245 by means of a fastener such as a screw to enclose the electric wire 246 and the rotation shaft 243 between the rotation shaft cover 241 and the pivot seat 245. Thus, the pivoting of the two shafts 243 and the adapter 243A fixedly connected thereto will not have any effect on the electrical wires 246 disposed therein, and this concealed design is highly advantageous for achieving a satisfactory product appearance of the photographic lamp 20 and for protecting the electrical wires 246 from abrasion or external moisture and dust.

Further, in order to achieve rotational positioning of the pivoting member 24, a plurality of elastic members 244 are preferably provided between the rotation shaft cover 241 and the pivoting seat 245. As shown in fig. 11, a pair of elastic members 244 are interposed between the rotation shaft 243 and the pivot mount 245 and the locking member 242 by means of the locking member 242 such as a lock nut, whereby if it is desired to achieve locking of the pivoting member 24 to adjust the force for driving the pivoting thereof or the damping effect of the self-contained, it is possible to drive these elastic members 244 between the damped position of the abutment between the members abutted thereto and the released position of releasing the abutment by screwing or unscrewing the locking member 242 by means of its own rotation, thereby achieving rotational positioning of the pivoting member 24 at low cost and in a convenient manner for the user.

Thereby, with the pivoting member shown in fig. 11, unidirectional pivoting between adjacent lamp holders is achieved in a relatively simple, easily mass-produced structure. Further, if it is desired that the pivoting member can perform the function of bi-directional pivoting, only the pivoting seat 245 is required to be changed from a single member to a counter-pivoting member capable of pivoting with respect to each other, and at this time, only a simple and small-effort change of the mold of the unidirectional pivoting member is required, which is advantageous in reducing the manufacturing cost of the pivoting member. It should also be noted that since the pivot member structures shown herein are identical, the worker need not very carefully match the mating relationship between the pivot member and the lamp bracket when assembling the lamp, thereby avoiding the possibility of misassembly during lamp assembly.

Similar to the first embodiment, magnetic members are provided at opposite sides between the sub-lamp frames 11B and 11C, and poles of opposite sides in the opposite magnetic members are different, so that the sub-lamp frames 11B and 11C can be magnetically connected with each other by the magnetic members. When the sub-frame 11B rotates to be mutually attached to the side surface of the sub-frame 11C, the magnetic member therebetween can fix the sub-frame 11C to the sub-frame 11B, thereby avoiding the shake of the sub-frame 11C and improving the stability of the photographic lamp 20 in the hard-light state.

As a further preferred aspect of the invention, a further development of the photographic light fixtures 10 and 20 of fig. 1 to 3 and 8 to 9 is shown in fig. 12A and 12B, wherein a recognition means 51 is added to the foremost lamp holder 11D of the photographic light fixtures 10 and 20, wherein the recognition means 51 may be, for example, a camera with face recognition function; and a plurality of first actuating mechanisms 52A and 52B and a second actuating mechanism 53 respectively provided at the plurality of pivoting members and controlling rotation of the rotation shafts of the pivoting members, wherein the plurality of first actuating mechanisms 52A and 52B and the second actuating mechanism 53 are in signal communication with the identification mechanism 51 and the operation knob 26, respectively.

Thus, when the photographic lamp 10 and 20 with the improvements of fig. 12A and 12B are used, for example, the functions of recognizing and tracking the face of the user, recognizing the illuminance of the face of the user, and the like can be realized by means of the recognition mechanism 51, and the recognition result is compared with the use modes preset in the lamps 10 and 20, so that the included angle between the lamp holders and/or the color temperature and brightness of the light emitted by the lamp bands can be adaptively adjusted. By adding the identification mechanism 51 and the plurality of actuation mechanisms 52A, 52B and 53 in signal communication therewith, the luminaire can be "intelligent" without significantly increasing costs, thereby significantly reducing the learning costs of a new product for a user and improving the user experience of the new product, which is highly advantageous for making the user more willing to try and accept and use the new photographic luminaire 10 and 20 in accordance with the present invention.

Here, the plurality of first actuating mechanisms 52A may be external brushless motors and the second actuating mechanism 53 may be built-in brushless motors. The use of a brushless motor helps to keep the appearance of the photographic light fixtures 10 and 20 of the present invention neat and beautiful.

As a further preferred aspect of the invention, a further improvement of the photographic light fixtures 10 and 20 of fig. 1-3 and 8-9 is shown in fig. 13, wherein it is noted that the improvements of fig. 12A-B and 13 are compatible with each other.

To ensure a better lighting effect, it is desirable to increase the light-emitting power of the lamp strip 12 as much as possible. In order to ensure a long life of the photographic light fixtures 10 and 20, it is advantageous to efficiently cool the lamp strip 12 and the lamp holder 11A. For this purpose, as shown in fig. 13, the lamp strip 12 is cooled by means of an aluminum plate on the lamp holder 11A mainly in a "heat conduction" manner, in contrast to the arrangement of the lamp strip 12 on the lamp holder 11A shown in fig. 1 to 3, wherein the lamp strip 12 is cooled by means of an aluminum plate built into the hollow lamp holder 11A and the lamp strip 12 is assisted in a "heat convection" manner by means of a fan 61 located at one end of the lamp holder 11A. As shown in fig. 13, wherein the lamp strip 12 is fixedly arranged inside the hollow lamp holder 11A by means of an aluminum plate, this allows the lamp strip 12 to be positioned inside the hollow lamp holder 11A in a "floating" manner, since the lamp holder 11A has a substantially rectangular cavity. Accordingly, a fan 61 is provided at one end of the lamp holder 11A to forcibly drive the airflow 62 to rapidly flow toward the lamp strip 12 and perform "heat convection" heat dissipation with the surface thereof. In other words, in fig. 13, the heat exchange efficiency of the lamp strip 12 is significantly improved by forced convection heat exchange of the air flow 62 in addition to the heat conduction and heat dissipation of the existing aluminum electrode plate.

Of course, in addition to the forced flow of air 62 through the light strip 12 by means of the blower 61 to enhance heat dissipation, it is also possible to adapt the internal cavity in the hollow light holder 11A by means of the feature that the photographic light fixtures 10 and 20 are held in a generally vertical orientation, so that a "chimney effect" of hot air is created in the vertically arranged internal cavity to achieve a directional flow of air 62 to cool the light strip 12. This may, for example, design the right end air inlet of the hollow lamp holder 11A of fig. 13 to be larger than the left end air outlet, thereby forming a tapered cavity having a slope of 10-25 degrees inside the hollow lamp holder 11A. By means of such tapered cavities with inclination, the hot air is allowed to form a "chimney effect" of directional flow of the air flow 62 inside the hollow lamp holder 11A, so that "heat convection" heat dissipation can be achieved without the fan 61.

It is also desirable to note that since the high heat light strip 12 is built into the hollow light holder 11A, the risk of scalding the user due to overheating of the light fixture is reduced.

A third embodiment of the present application is described below with reference to fig. 14-16A-B, which is a further modification of the second embodiment, and parts not specifically described include the same reference numerals and text descriptions as those of the second embodiment, and are not repeated here.

The main improvement of the third embodiment over the second embodiment is that in the third embodiment of the present invention, a multi-directional pivot 23, which can be used as the first pivot as shown in fig. 16A-16B, is employed, allowing a wider range and wide angular adjustment of the photographic light fixture 20, which makes the working posture of the photographic light fixture 20 richer and more varied to meet the lighting requirements of more application scenarios.

In particular, the first, multidirectional pivoting member 23 as shown in fig. 16A-16B is improved over the pivoting member 24 shown in fig. 11 in that adjacent two of the adapters 35 are pivotable about second and third pivot axes A2a and A3, respectively, orthogonal to first pivot axes A1a and A1B, respectively, that are parallel to each other, relative to the axes of rotation to which they are connected, which axes of rotation are about first pivot axes A1a and A1B, respectively. Since two adjacent swivel joints 35 of the multidirectional pivot 23 are connected to different lamp holders (e.g. 11B and 11C), respectively, this allows the different lamp holders to change the angle between them by pivoting the spindle about the first pivot axis A1a and A1B on the one hand, and to change the luminous surface orientation and posture of the lamp holder (e.g. 11B) itself connected thereto by pivoting about the second pivot axis A2a orthogonal to the first pivot axis and/or to change the lamp holder (e.g. 11C) connected thereto by pivoting about the third pivot axis A3 orthogonal to the first pivot axis on the other hand. Thereby, the photographic lamps 10 and 20 with the first and the multi-directional pivoting members 23 as shown in fig. 16A-16B can easily rotate relatively in two planes orthogonal to each other, so that the combination mode of two lamp belts arranged on adjacent lamp brackets can be matched and increased, and the photographic lamps 10 and 20 with a larger range and wide angle adjustment can be realized

As is apparent from the above description of the three embodiments, compared with the prior art, the folding photographic lamp provided by the present invention is provided with the main lamp holder and the sub lamp holder, both of which are rotatably connected by means of the first pivoting member capable of rotating in two directions, and the lamp holders are formed in different shapes by rotating the first pivoting member. For example, the auxiliary lamp holders are connected with the ends of the main lamp holder along the length direction to form a linear light source suitable for shooting the side face of a person, and the linear light source is in a hard light form at the moment, or the auxiliary lamp holders and the main lamp holder are folded together, so that the size can be remarkably reduced and the linear light source is convenient to carry or transfer, or an included angle is formed between the auxiliary lamp holders and the main lamp holder, for example, a V shape which can enable light rays to meet at different heights and different angles is formed, and at the moment, a light effect of 'up lamp and down lamp' can be formed by the light bands on the main lamp holders and the light bands on the auxiliary lamp holders, so that the lamp is in a soft light form. Therefore, according to the invention, the use forms which are in various forms and are obviously distinguished in illuminance can be realized by means of a single lamp, the illumination range of the lamp is enlarged, and meanwhile, the illumination directions of the lamp strip of the main lamp bracket and the lamp strip of the auxiliary lamp bracket are flexibly changed, so that a satisfactory lighting effect is realized.

While the invention has been described in detail in connection with only a limited number of embodiments, it should be readily understood that the invention is not limited to such disclosed embodiments. Rather, the invention can be modified by incorporating any number of variations, alterations, substitutions, or equivalent arrangements not heretofore described, but which are commensurate with the spirit and scope of the invention. Further, while various embodiments of the invention have been described, it is to be understood that aspects of the invention may include only some of the embodiments. Accordingly, the invention is not to be seen as limited by the foregoing description, but is only limited by the scope of the appended claims.
