[0029] Reference is made to the accompanying Figures 1-6As shown in the figure, it is a kind of photographic lampshade, the lampshade 1 includes a reflector cup 2, the lampshade 1 further includes a shell 3, the shell 3 covers the outside of the reflector cup 2, the front end of the shell 3 is fixed with the front end of the reflector cup 2, the rear end of the shell 3 is fixed with the rear end of the reflector cup 2, the inner wall of the shell 3 and the outer wall of the reflector cup 2 form a closed gap 4, the front end and the rear end of the shell 3 have openings to adapt to the light in and out of the reflector cup 2; the front end of the shell 3 is provided with a chuck 5 for connecting with a photographic camera lamp, the chuck 5 is provided with a light inlet 50, so that the light of the photographic camera lamp enters the reflector cup 2 through the light inlet 50.
[0030] The reflector cup 2 penetrates along the front and rear ends, and expands gradually along the radial direction from front to back, and is trumpet-shaped. The light enters from the front end of the reflector cup 2 and is emitted from the rear end after being reflected by the inner wall of the reflector cup 2. The extension trend of the inner wall of the reflector cup 2 is approximately a parabola, so that the direction consistency of the light emitted by the light source is higher after being reflected by the inner wall of the reflector cup 2, so as to better adjust the direction of the light emitted by the light source. The inner wall of the reflector cup 2 can be provided with a reflective structure to adjust the reflection effect of the light, for example, a plurality of rectangular reflective structures are arranged on the inner wall of the reflector cup 2 to adjust the reflection angle of the light so that the light is emitted at a preset angle.
[0031] Correspondingly, the shell 3 is trumpet-shaped, and its inside penetrates along the front and rear directions to be fitted on the periphery of the reflector cup 2, and the openings at the front and rear ends avoid interfering with the light entering and exiting the reflector cup 2.
[0032] The gap 4 is formed between the inner wall of the shell 3 and the outer wall of the reflector cup 2, which is equivalent to a heat insulation layer and can reduce the heat transfer between the reflector cup 2 and the shell 3. After the lamp works for a long time, the temperature of the shell 3 will not be too high, which shortens the waiting time for cooling down of the staff and enables the photographic camera lamp 7 to be quickly disassembled and stored after shooting. At the same time, the gap 4 has a certain buffering effect and can reduce the direct impact of the stress on the reflector cup 2. The width of the gap 4 can be designed according to the power of the lamp 7 to which the lampshade 1 is applied, and the width range can generally be selected between 1mm and 1cm. Generally, the width of the gap 4 of the lampshade 1 applied to a low-power lamp 7 is relatively small, while the width of the gap 4 of the lampshade 1 applied to a high-power lamp 7 is relatively large.
[0033] There are various ways to form the gap 4 between the shell 3 and the reflector cup 2, for example, the curvature of the inner wall of the shell 3 is different from that of the outer wall of the reflector cup 2, such as the curvature of the inner wall of the shell 3 is greater than that of the outer wall of the reflector cup 2, so that a closed gap 4 is formed between the two from the front end to the rear end. Or the curvature of the shell 3 and the reflector cup 2 is consistent, and the radial size of the shell 3 is greater than that of the reflector cup 2, so as to form the gap 4.
[0034] The material of the shell 3 is preferably metal, which has a hardness and thickness greater than those of the reflector cup 2, so that the reflector cup 2 can be effectively prevented from being deformed or damaged due to external impact, and the reflector cup 2 is well protected. Moreover, since there is a gap 4 between the inner wall of the shell 3 and the outer wall of the reflector cup 2, the impact force received by the shell 3 is buffered in the gap 4, so that the impact force is not directly transmitted to the reflector cup 2, thereby achieving protection of the reflector cup 2.
[0035] In some embodiments, the front end of the shell 3 extends inwardly to form a mounting platform 30, the front end of the reflector cup 2 extends inwardly to form a connecting plate 20, the front end surface of the connecting plate 20 is attached to and fixed on the inner end surface of the mounting platform 30, and the chuck 5 is fixed on the front end surface of the mounting platform 30.
[0036] The front end of the shell 3 has an opening which is adapted to the light inlet of the front end of the reflector cup 2 and is generally circular. A ring-shaped mounting platform 30 is formed inwardly along the edge of the opening in the front end of the shell 3, and a connecting plate 20 is formed inwardly along the front end of the reflector cup 2. The front end surface of the connecting plate 20 is attached to the inner end surface of the mounting platform 30 and is locked by a screw. In this way, the connecting mode of surface-to-surface attachment and locking is adopted between the two, so as to achieve close cooperation between the structures, ensure the airtightness of the gap, reduce the air flow between the gap and the outside, and be conducive to ensuring the heat insulation effect. The chuck 5 is fixed on the outside of the mounting platform 30 and can also be locked and connected by a screw. A light inlet 50 is formed in the middle of the chuck 5 so as to allow the light to normally enter the reflector cup 2. The chuck 5 is usually detachably connected to the photographic and video lighting fixture 7 by a buckle structure, for example, a protruding clamping block is arranged on the chuck 5 and is connected to a corresponding clamping groove on the photographic and video lighting fixture 7.
[0037] In some embodiments, the rear end of the reflector cup 2 extends outwardly to form a flange 21, and the rear end of the shell 3 extends outwardly to form a positioning plate 31. The rear end surface of the positioning plate 31 abuts against and is fixed on the front end surface of the flange 21.
[0038] The flange 21 at the rear end of the reflector cup 2 and the positioning plate 31 at the rear end of the shell 3 both extend radially outwardly, the rear end surface of the positioning plate 31 abuts against and is fixed on the front end surface of the flange 21, so as to achieve close connection of the rear ends of the reflector cup 2 and the shell 3, ensure the airtightness of the gap, and reduce the air flow to ensure the heat insulation effect. Moreover, the flange 21 and the positioning plate 31 both extend outwardly, so as to avoid interference with the light emitted into the reflector cup 2.
[0039] Further, the outer side of the flange 21 is provided with an annular pressing plate 6. The pressing plate 6 is annular, and is matched with the shape of the flange 21, and is pressed on the outer side of the flange 21, and cooperates with the positioning plate 31 to clamp and fix the flange 21 therein, which is beneficial to strengthen the connecting strength of the reflector cup 2 and the shell 3, and also protects the position of the flange 21 of the reflector cup 2.
[0040] The pressing plate 6, the flange 21 and the positioning plate 31 can be locked by screws. Specifically, a plurality of groups of screw holes corresponding to each other are formed on the pressing plate 6, the flange 21 and the positioning plate 31, and a screw is arranged in each group of screw holes.
[0041] Referring to the accompanying drawings Figure 7 A photographic and video shooting lamp 7 is provided, the lamp 7 is provided with a light source, and the light source is provided with the lampshade 1 as any one of the preceding embodiments, and the lampshade 1 is connected with the lamp 7 through the chuck 5.
[0042] The body of the lamp 7 is provided with a power circuit assembly, a light source and other structures, the light source is exposed and mounted, and the lampshade 1 is connected and fixed with the lamp 7 through the chuck 5 at the light source, so that the light emitted by the light source is emitted after being processed by the reflector cup 2 in the lampshade 1.
[0043] After the lamp 7 works for a long time, the temperature of the shell 3 is greatly lower than the temperature of the reflector cup 2 due to the heat insulation gap 4 between the shell 3 and the reflector cup 2, which effectively shortens the waiting time required for dismounting the lampshade 1, improves the working efficiency, effectively reduces the probability of personnel scalding, and improves the safety of the lamp 7.
[0044] The light source can adopt an LED lamp panel, which is arranged in the light inlet of the chuck, and the surface of the LED lamp panel is flush with the front end surface of the reflector cup. In this way, most of the light can be emitted at a predetermined angle to achieve the optimal lighting effect.
[0045] The above only describes preferred embodiments of the present application, and is not used to limit the present application. For those skilled in the art, the present application can have various changes, combinations and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the scope of the claims of the present application.
