Description

A photography luminaire for photography and videography

Technical Field

The invention relates to the field of equipment related to camera shooting, in particular to a photographic lamp for photographic camera shooting.

Background

Under the condition that most of light is insufficient, the help of a photographic lamp is usually needed, the photographic lamp can obviously increase the exposure of the underexposed part of a shooting main body, so that the light supplementing effect is achieved, the photographic lamp is only used for improving the exposure of the underexposed part of the shooting main body, namely, only the photographic lamp is needed to irradiate a certain local part, therefore, a circle of light barrier is arranged on the periphery of a lampshade of the common photographic lamp at present, most of the light barrier is black, the most main purpose of the light barrier is to reduce the light quantity by reducing light and shading, therefore, some workers in the circle are also called as the light absorption plate and the light reduction plate, in addition, the light barrier can be used as a black background to support the shooting main body, most of the light barrier is directly and fixedly arranged on the periphery of the lampshade at present, and the angle adjustment of the light reduction plate can;

the patent application document with the patent number of 201720707335.6 and the patent name of light barrier component for photographic lamp, which is published in 2017 by the national intellectual property office, provides two implementation technical schemes through compressing the keywords to the keywords such as 'photography' or 'camera shooting' or 'telescopic' or 'adjustment' or 'cover' or 'plate' and the like and repeatedly combining and searching and comparing for a plurality of times; one is that only one of the rotating shafts needs to be rotated, and the linkage of the other three rotating shafts can be realized. Therefore, only one of the light barriers 32 needs to be adjusted, the other light barriers 32 can act together, and the light barriers 32 can synchronously move through adjusting the bevel gears, so that the swinging angles are consistent and the light barriers are opened or closed together; the other is "the seventh bevel gear 347 and the eighth bevel gear 348 are not included," the micro motor 4 is installed at the position of the seventh bevel gear 347 or the eighth bevel gear 348, and the micro motor 4 is fixedly connected with the light-blocking plate frame 31 through a fastener, "so it is easy to see that the applicant of the case has the most important purpose of providing a technical scheme capable of adjusting the angle of the light-blocking plate at the periphery of the lens of the camera head in order to overcome the defects of the prior art that the number of the light-blocking plates on one camera lamp is four, each adjustment requires that the light-blocking plate is turned over individually and needs to be adjusted four times continuously, and the adjustment of one camera lamp can be completed, which needs to be described in the section that the technical scheme only considers the convenience of angle adjustment, but completely neglects the convenience of storage and the importance of carrying after storage, and a person skilled in the art can understand that, since the four light-blocking plates are all linked by using the rotating shafts and the bevel gears, when the edges of the four light barriers are completely abutted, the light barriers cannot be further folded, the space occupied by the whole photographic lamp is the largest, and certainly, the light barriers can be completely turned outwards to be attached to the outer wall of the lamp body by a person skilled in the art, the space occupied by the whole photographic lamp is the smallest, but the lamp cap component part of the photographic lamp is completely exposed, so that due protection cannot be obtained completely, and the transportation and carrying after the storage are not mentioned;

the patent application document with patent number '201920882077.4' published by the national intellectual property office in 2019 as 'anti-glare infrared image camera' provides a camera light baffle plate (8) which can be contained in a connecting box (2) and driven by an electric push rod (3), therefore, the applicant of the proposal can easily see that the electric push rod (3) is used as an external axial driving force to push the light barrier (8) to move in and out, of course, the electric push rod (3) can also be applied to the technical content of the technical solution in the previous paragraph by those skilled in the art for axially pushing one of the light barriers to achieve the common linkage of the other three light barriers, however, no matter how the light barrier is combined or the light barrier is technically overlapped, the final purpose that the head of the photographic lamp assembly can be completely accommodated in a relatively sealed protective cavity for protection while the light barrier is folded and accommodated cannot be achieved.

Detailed Description

In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the invention easy to understand, the technical scheme in the embodiment of the invention will be clearly and completely described below with reference to the attached drawings in the embodiment of the invention.

Referring to fig. 1-2, the present embodiment is implemented by adopting the following technical scheme, which includes a casing 1, the casing 1 is a hollow cuboid structure as a whole, a pan/tilt head 2 for butting with a tripod is fixedly installed at a lower bottom surface of the casing 1, a camera lamp set 3 capable of sliding in a clearance fit with the casing 1 is arranged inside the casing 1, positioning edges 4 are respectively and vertically fixed at four corners of an end portion of the casing 1, a positioning sleeve 5 in clearance slide fit with an outer side surface of the casing 1 is arranged at the outer side surface of the casing 1, first light blocking plates 6 capable of being rotatably connected and matched with the casing 1 are respectively installed at upper and lower sides of the casing 1, and second light blocking plates 7 capable of rotatably connected and matched with the casing 1 are respectively installed at left and right sides of the casing 1;

Due to the adoption of the technical scheme, the invention has the following beneficial effects: simple structure, the in-process of using can be effectual can adjust the angle that opens and shuts of barn door by oneself as required.

The following will further explain the application method and the principle of the technical solution part in this embodiment with reference to the accompanying drawings:

when the camera lamp set is used, firstly the positioning nut 22 is loosened, then the positioning sleeve 5 pushes the camera lamp set 3 to do axial piston-type motion in the machine shell 1, the opening and closing angles of the first light barrier 6 and the second light barrier 7 are respectively adjusted by the first limiting shaft 12 and the second limiting shaft 16 in the moving process of the camera lamp set 3, namely the opening angle of the camera lamp set 3 moving the first light barrier 6 and the second light barrier 7 towards the positioning edge 4 is larger;

because the included angles are arranged between the second guide chute 15 and the first guide chute 13 and between the fourth guide chute 19 and the third guide chute 17, after the light blocking device is completely accommodated, all the first light blocking plates 6 and the second light blocking plates 7 can be retracted between the four positioning edges 4, and meanwhile, the ground glass part at the head of the photographing lamp group 3 is also positioned in a relatively closed space formed by the four positioning edges 4, so that the occupied space in the carrying process is greatly reduced, and the safety in the transportation process is also improved.

Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
