Technical Field
[0001] The invention relates to the technical field of lighting lamps, in particular to a spotlight LED lamp with a built-in reflective cup. Background Art
[0002] A spotlight LED lamp with a built-in reflector cup refers to a lamp that combines an LED light source with a reflector cup. The light emitted by the LED is focused and reflected through the special design of the reflector cup to achieve a spotlighting effect. This type of lamp is usually used in scenes that require a combination of high brightness and long-distance illumination, such as outdoor lighting.
[0003] In the process of film and television shooting, spotlight LED lights are often used for large-area lighting and special lighting in stunt shooting. The position of the light can be flexibly adjusted under the control of the photographer to meet complex shooting needs. In addition, spotlights can also be combined with other lights to create special light and shadow effects, such as light beams passing through clouds and starlight twinkling, etc., to add visual beauty to film and television works. However, when the spotlight LED light switches mode, since the lighting of the LED light is divergent, it is necessary to add a reflector cup to increase the brightness and irradiation distance. However, due to the fixed curvature of the reflector cup, the light source formed by the laser LED light is consistent, and it is difficult to adjust the irradiation distance of the laser LED light.
[0004] The prior art often uses multiple spotlight LED lamps for lighting. When long-distance lighting is needed, a spotlight LED lamp with a large reflective cup curvature is turned on, or a spotlight LED lamp with a narrow outlet is used. When close-range lighting is needed, the previous spotlight LED lamp is turned off, and a spotlight LED lamp with a small reflective cup curvature is turned on, or a spotlight LED lamp with a large opening is used. When multiple LED lamps are used, the switching process is cumbersome, and multiple spotlight LED lamps need to be controlled synchronously. At the same time, multiple spotlight LED lamps will cause a waste of resources, and the adjustment of the irradiation distance and brightness are fixed, which is not convenient for adjusting to the required brightness and irradiation distance, thereby affecting the controllability of the light brightness and irradiation distance during film and television shooting.
[0005] Based on this, in order to solve the problem that it is difficult to adjust the brightness and irradiation distance of a single spotlight LED lamp to meet different lighting requirements during filming, the present invention designs a spotlight LED lamp with a built-in reflective cup. Summary of the invention
[0006] The present invention provides a spotlight LED lamp with a built-in reflective cup; the problem that it is difficult to adjust the brightness and irradiation distance of a single spotlight LED lamp to meet different lighting requirements during filming of movies and TV shows is solved; the brightness range of the spotlight LED lamp is adjusted by changing the convergence and divergence of the LED light at the lamp holder; at the same time, the irradiation distance and irradiation area of the emitted light are adjusted by means of the principle of rotation and opening and closing, thereby improving the controllability of the brightness and irradiation distance of the single spotlight LED lamp during filming of movies and TV shows.
[0007] In order to achieve the above object, the present invention provides the following technical solutions:
[0008] The present invention provides a spotlight LED lamp with a built-in reflector cup, comprising a housing, a lamp holder, a reflector cup body, a rotating ring, a lever, a driving mechanism, an adjusting mechanism, and a reflector plate. The lamp holder is installed in the housing, the reflector cup body is installed at the front end of the lamp holder, the rotating ring is installed at the front end of the lamp holder, the lever is located at the side of the rotating ring and passes through the housing, the driving mechanism is located on the rotating ring, the adjusting mechanism is installed between the reflector cup body and the rotating ring, and the reflector plate is installed at the reflector cup body. When long-distance irradiation is required, the lever drives the driving mechanism at the rotating ring to gradually gather the light at the lamp holder, and the adjusting mechanism drives the reflector plate to change the angle of diffuse reflection of the light.
[0009] The lever drives the driving mechanism, which changes the position of the reflector through the adjusting mechanism, so that the bottom of the reflector fits with the base, and the light will only flow from the reflector. At the same time, the reflector has been folded at this time, and gradually forms a gathered shape from a scattered state. When it moves to the extreme position, the free ends of the reflectors form a perfect circle with each other, and the light will only flow in the reflector. At this time, the reflective cup composed of the reflector has a smaller outlet diameter than the reflective cup body, and the range of light irradiation is smaller, but the focusing distance is farther. At the same time, the driving mechanism also gradually opens the number of light bulbs blocked at the lamp holder, so that the light bulbs can be directly irradiated without reflection, thereby increasing the brightness of the emitted light.
[0010] Preferably, the driving mechanism comprises a fixed ring, a slide groove, a fixed shaft, a slider, and a movable groove; the fixed ring is mounted on the housing, the slide groove is provided on the upper surface of the rotating ring, the fixed shaft is located in the slide groove and slides, the slider is mounted above the rotating ring, the number of the sliders is six, the slider is penetrated by the fixed shaft, the movable groove is provided on the fixed ring, and the top of the fixed shaft is mounted in the movable groove and slides;
[0011] By adopting the principle of rotating opening and closing, the aperture formed between the sliders gradually increases, thereby improving the brightness of the light.
[0012] Preferably, the adjustment mechanism comprises a mounting frame, a movable rod, a wedge block, and a torsion spring, wherein the mounting frame is mounted between the lamp holder and the housing, the reflector is mounted on the mounting frame, the movable rod is mounted on the reflector, and the top of the movable rod is a wedge-shaped surface, the wedge block is mounted above the fixed shaft, the bottom surface of the wedge block is adjacent to the wedge surface of the movable rod, and the torsion spring is mounted between the reflector and the mounting frame;
[0013] A gear rack can also be used here. During the movement of the slider, a rack is added to the upper surface of the slider. The rack can drive the gear added to the reflector to rotate, thereby driving the reflector to fold. Although the torsion spring is saved at this time, the meshing accuracy of the gear rack is relatively high, and it will cause greater obstruction to the light when located in the internal transmission. The structure of the wedge block and the movable rod here is more flexible. With the cooperation of the wedge block and the wedge surface on the movable rod, the reflector can be driven to rotate around the mounting frame as a whole, gradually forming a gathered reflective cup, reducing the aperture of light emission, and increasing the brightness and distance of light irradiation.
[0014] Preferably, the reflector is divided into a gathering part and a dispersion part, the inner surface of the reflector is arc-shaped, a reflector is installed on the back of the dispersion part, the top of the reflector is located in the middle of the reflector cup body in the initial state, the gathering part is the front end of the mounting frame, and is used to concentrate the light in the gathering state, and the dispersion part is the rear end of the mounting frame. When the reflector is in the initial state, the dispersion part will pass through the reflector on its back, and then the light will be reflected by the reflector to between the reflector and the reflector cup body. At this time, part of the light will be irradiated outward from the edge of the reflector cup body, thereby increasing the irradiation range of the light.
[0015] Preferably, the cross-section of the slider is an irregular shape, and in an initial state, multiple top ends of the sliders form a circular hole, and the thickness of the slider gradually decreases from bottom to top. A focusing mirror is installed on the side of the slider facing the lamp holder, and multiple top ends of the sliders in the initial state can also be directly closed, but in this case, another hole needs to be opened on the fixed plate, and the light source directly shines on the focusing mirror from the other hole. At this time, it is necessary to set the thickness of the slider to gradually increase from bottom to top, and then the light source will flow directly from between the reflector and the reflective cup body under the influence of the focusing mirror, thereby increasing the irradiation range.
[0016] Preferably, a baffle with the same curvature is installed at the edge of the reflector, and the baffle is in contact with the edge of the adjacent reflector in the gathered state. The baffle is used to fill the gap between the reflectors when the reflectors are gathered, thereby avoiding gaps between the reflectors when they are gathered.
[0017] Preferably, the reflective cup body is in a hyperbolic shape, and in the initial state, the top of the reflector is located at the center of the reflective cup body along the light irradiation line. This is the second style of the reflective cup body. At this time, the reflective cup body is in a hyperbolic shape. Then, when the reflector is in a dispersed state, the light is transmitted along the inner wall of the reflective cup body to the center of the reflective cup, and a new reflective cup is formed at the front end of the center of the reflective cup body, further expanding the irradiation range.
[0018] Preferably, the slider and the fixed shaft are made of translucent glass, and the outer wall of the reflective plate is coated with a reflective coating, so that the light is not weakened by reflection of the reflective coating on the outer wall of the reflective plate.
[0019] The beneficial effects of the present invention are as follows:
[0020] 1. The present invention provides a spotlight LED lamp with a built-in reflector cup. When the light distance needs to be increased, the lever drives the driving mechanism, and the driving mechanism changes the position of the reflector through the adjusting mechanism, so that the bottom of the reflector fits with the base, and the light will only flow from the reflector. At the same time, the reflector has been folded, and gradually changes from a scattered state to a gathered state. When it moves to the extreme position, the free ends of the reflectors form a perfectly fitting circle with each other, and the light will only flow in the reflector. At this time, the reflector cup formed by the reflector has a smaller outlet diameter than the reflector cup body, and the range of light irradiation is smaller, but the focusing distance is farther. At the same time, the driving mechanism also gradually opens the number of light bulbs blocked at the lamp holder, so that the light bulbs are directly irradiated without reflection, thereby increasing the brightness and irradiation distance of the emitted light.
[0021] 2. The present invention proposes a spotlight LED lamp with a built-in reflective cup. Under the action of the lever, the aperture formed by the slider is driven to gradually increase. At the same time, the slider also slides horizontally in the slide groove. The mounting frame is annular and the cross-sectional shape of the mounting frame is circular, so that the reflective plate can rotate around the mounting frame. When the slider moves horizontally, the fixed shaft pushes the wedge block to move along the movable groove direction, and then gradually squeezes the movable rod, and then drives the reflective plate as a whole to rotate around the mounting frame, gradually forming a gathered reflective cup, reducing the aperture of light emission, and improving the brightness and distance of light irradiation.
[0022] 3. The present invention proposes a spotlight LED lamp with a built-in reflector cup, wherein the focusing part is the front end of the mounting frame, which is used to concentrate the light in the focusing state, thereby reducing the diameter of the reflector cup formed by the reflector plate, further reducing the dispersion of the light, improving the light brightness and the irradiation distance, and reducing the irradiation range, and the dispersion part is the rear end of the mounting frame. When the reflector plate is in the initial state, the dispersion part will pass through the reflector on the back of the dispersion part, and then the light will be reflected by the reflector to between the reflector plate and the reflector cup body. At this time, part of the light will be irradiated outward from the edge of the reflector cup body, thereby increasing the irradiation range of the light; in addition, the light irradiated outward along the edge of the reflector cup body will form relatively parallel soft light, thereby improving the irradiation effect at a close distance; and after the reflector plate is folded, the dispersion part is in contact with the lamp holder, thereby the light will not flow outward from the gap between the reflector plate and the reflector cup body, thereby improving the light brightness and the focusing irradiation effect, thereby increasing the irradiation distance of the light.

DETAILED DESCRIPTION
[0033] In order to better understand the above solution, the above technical solution is described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0034] like Figure 1-2 As shown, it includes a shell 1, a lamp holder 2, a reflector cup body 3, a swivel 4, a lever 5, a driving mechanism 6, an adjustment mechanism 7, and a reflector 8. The lamp holder 2 is installed in the shell 1, the lever 5 is located on the side of the swivel 4 and penetrates the shell 1, and the swivel 4 is installed at the front end of the lamp holder 2. The spotlight LED lamp here can be handheld or fixed. If it is handheld, a lock can be added to the lever 5 to fix the reflector 8 to adjust the front and rear positions. If it is fixed, that is, fixed on the ground, wall or other placed objects, the lever 5 here can be driven by a motor plus a group of gear sets. It only needs to keep the lever 5 started, and the gear set is driven by the motor to rotate. The gear set drives the lever 5 to rotate through the transmission ratio, thereby realizing the adjustment of the light.
[0035] The reflective cup body 3 is installed at the front end of the lamp holder 2. The reflective cup body 3 is used to gather light. The reflective cup body 3 can be selected in various ways. Since the irradiation range and irradiation brightness of light can be adjusted in the present application, the reflective cup body 3 is set to be parabolic or hyperbolic, so that the irradiation area can be increased when the light is emitted from the reflective cup body 3. At the same time, the curvature of the reflective cup body 3 can also be used to change the focusing position of the emitted light, thereby controlling the luminous distance of the emitted light after reflection by the reflective cup; the driving mechanism 6 is located on the rotating ring 4, the adjusting mechanism 7 is installed between the reflective cup body 3 and the rotating ring 4, and the reflector 8 is installed at the reflective cup body 3. When long-distance irradiation is required, the lever 5 drives the driving mechanism 6 at the rotating ring 4 to gradually gather the light at the lamp holder 2, and the adjusting mechanism 7 drives the reflector 8 to change the angle of diffuse reflection of the light.
[0036] like Figure 7As shown, under normal circumstances, the reflector 8 is in an unfolded state. At this time, the light at the lamp holder 2 is blocked by the driving mechanism 6 and gradually focused to the circular hole formed by the slider 64, and then refracted by the reflector cup, thereby improving the focusing effect of the light. The opening and curvature of the reflector cup are fixed, and thus the area of the light emitted and the luminous distance are also fixed; at the same time, the light will be transmitted outward through the position between the reflector 8 and the reflector cup body 3, and then the light will be transmitted outward along the side wall of the reflector cup, further increasing the irradiation area of the light.
[0037] When the light distance needs to be increased, the lever 5 drives the driving mechanism 6, and the driving mechanism 6 changes the position of the reflector 8 through the adjusting mechanism 7, so that the bottom of the reflector 8 fits with the base, and the light will only flow from the reflector 8. At the same time, the reflector 8 has been folded at this time, and then gradually forms a gathered shape from a scattered state. When it moves to the extreme position, the free ends of the reflector 8 form a perfectly fitting circle with each other, and then the light will only flow in the reflector 8. At this time, the reflective cup composed of the reflector 8 has a smaller outlet diameter than the reflective cup body 3, and the range of light irradiation is smaller, but the focusing distance is farther. At the same time, the driving mechanism 6 also gradually opens the number of light bulbs blocked at the lamp holder 2, so that the light bulbs can be directly irradiated without reflection, thereby improving the brightness of the emitted light.
[0038] like Figure 3-6 The driving mechanism 6 includes a fixed ring 61, a slide groove 62, a fixed shaft 63, a slider 64, and a movable groove 65; the fixed ring 61 is installed on the housing 1, the slide groove 62 is opened on the upper surface of the rotating ring 4, the fixed shaft 63 is located in the slide groove 62 and slides, the slider 64 is installed above the rotating ring 4, the number of the sliders 64 is six, the slider 64 is penetrated by the fixed shaft 63, the movable groove 65 is opened on the fixed ring 61, and the top of the fixed shaft 63 is installed in the movable groove 65 and slides.
[0039] The driving mechanism 6 here adopts the principle of rotation opening and closing. When the fixed ring 61 remains unchanged, the rotating ring 4 is driven to rotate through the lever 5. During the rotation of the rotating ring 4, the fixed shaft 63 on the slide groove 62 will be synchronously driven to rotate. However, the fixed shaft 63 is restricted by the movable groove 65 on the fixed ring 61, and can only move obliquely along the movable groove 65, thereby driving the slider 64 to move horizontally relative to the slide groove 62. At this time, the aperture formed between the sliders 64 gradually increases, thereby improving the brightness of the light.
[0040] The adjustment mechanism 7 includes a mounting frame 71, a movable rod 72, a wedge block 73, and a torsion spring 74. The mounting frame 71 is installed between the lamp holder 2 and the housing 1, the reflector 8 is installed on the mounting frame 71, the movable rod 72 is installed on the reflector 8, and the top of the movable rod 72 is a wedge-shaped surface, the wedge block 73 is installed above the fixed shaft 63, the bottom surface of the wedge block 73 is adjacent to the wedge surface of the movable rod 72, and the torsion spring 74 is installed between the reflector 8 and the mounting frame 71.
[0041] The adjusting mechanism 7 here adopts the principle of wedge matching. As described above, under the action of the lever 5, the aperture formed by the slider 64 will be driven to gradually increase, and the slider 64 will also slide horizontally in the slide groove 62. The mounting frame 71 is annular, and the cross-sectional shape of the mounting frame 71 is circular, so that the reflector 8 can rotate around the mounting frame 71. When the slider 64 moves horizontally, the fixed shaft 63 will push the wedge block 73 to move along the direction of the active groove 65, thereby gradually squeezing the active rod 72, which is located at the reflector. Although the moving direction of the wedge block 73 on the light board 8 is not completely consistent with the folding direction of the reflector 8, when the moving direction of the wedge block 73 squeezes the movable rod 72, it can give the movable rod 72 a component of force corresponding to the reflector 8 downward. Under the cooperation of the wedge block 73 and the wedge-shaped surface on the movable rod 72, the movable rod 72 on the reflector 8 is gradually pressed downward, thereby driving the reflector 8 as a whole to rotate around the mounting frame 71, gradually forming a gathered reflective cup, reducing the aperture of light emission, and improving the brightness and distance of light irradiation.
[0042] like Figure 7-8 As shown, the reflector 8 is divided into a gathering portion 81 and a dispersion portion 82, and the inner surface of the reflector 8 is arc-shaped; a reflector 821 is installed on the back of the dispersion portion 82, and in the initial state, the top of the reflector 8 is located in the middle of the reflector cup body 3 and is not in contact with the reflector cup body 3.
[0043] The gathering part 81 is the front end of the mounting frame 71, which is used to concentrate the light in the gathering state, thereby reducing the diameter of the reflective cup formed by the reflector 8, further reducing the dispersion of the light, improving the light brightness and the irradiation distance, and reducing the irradiation range. The dispersion part 82 is the rear end of the mounting frame 71. When the reflector 8 is in the initial state, the dispersion part 82 will pass through the reflector 821 on its back, and then the light will be reflected by the reflector 821 to between the reflector 8 and the reflector cup body 3. At this time, part of the light will be irradiated outward from the edge of the reflector cup body 3, thereby increasing the irradiation range of the light; in addition, the light irradiated outward along the edge of the reflector cup body 3 will form relatively parallel soft light, thereby improving the irradiation effect at a close distance; and after the reflector 8 is folded, the dispersion part 82 is in contact with the lamp holder 2, thereby the light will not flow outward from the gap between the reflector 8 and the reflector cup body 3, thereby improving the light brightness and the gathering irradiation effect, thereby increasing the irradiation distance of the light.
[0044] The cross section of the slider 64 is an irregular shape. In the initial state, the tops of the multiple sliders 64 form circular holes. The thickness of the slider 64 gradually decreases from the bottom to the top. The slider 64 is installed with a focusing mirror 641 on the side facing the lamp holder 2. During the gradual sliding of the slider 64, the circular hole at the top of the slider 64 is destroyed, but the area formed at the front edge of the slider 64 is gradually increased, and more and more LED lights are exposed. At this time, the light of the LED lamp is concentrated by the reflector 8; on the contrary, at the beginning, the light emitted by the LED lamp is blocked by the focusing mirror 641, a part of it will be reflected to the lamp holder 2, and the other part will be reflected on the surface of the focusing mirror 641 to the top of the slider 64, which will The irradiation area of the light above the slider 64 is increased, which, on the one hand, reduces the brightness of the light, and on the other hand, allows the light to be reflected by the reflector 821, so that the light can be transmitted outward from between the reflector 8 and the reflector cup body 3. It should be noted that when the reflector 8 is unfolded, the reflector 8 will not form a completely closed space with the reflector cup, and thus will not affect the normal focusing of the light by the reflector cup body 3. That is, while the reflector cup body 3 focuses the light, the focusing mirror 641 and the reflector 821 will transmit the light outward along the edge of the reflector cup body 3, thereby increasing the irradiation area of the light source of the reflector cup body 3 and reducing the brightness of the light source at a long distance, thereby avoiding glare and discomfort to the human body.
[0045] The edges of the reflectors 8 are provided with baffles 83 with the same curvature, and in the gathered state, the baffles 83 are in contact with the edges of the adjacent reflectors 8. The baffles 83 are used to fill the gaps between the reflectors 8 when the reflectors 8 are gathered, so as to avoid gaps between the reflectors 8 when they are gathered, thereby preventing light from leaking from the reflectors 8 to between the reflectors 8 and the reflective cup body 3, further reducing the irradiation area of the light, and increasing the irradiation distance and irradiation brightness of the light.
[0046] The reflective cup body 3 is in a hyperbolic shape, and in an initial state, the top of the reflective plate 8 is located at the center of the reflective cup body 3 along the line of light irradiation.
[0047] The second style of the reflective cup body 3 is shown here. At this time, the reflective cup body 3 is in a hyperbolic shape. Then, when the reflector 8 is in a dispersed state, the light is transmitted along the inner wall of the reflective cup body 3 to the center position of the reflective cup body 3. A new reflective cup is formed at the front end of the center position of the reflective cup body 3. The reflective cup has a large curvature, and the point of the light (i.e., the center position) is close to the aperture. Therefore, the light gathered from the center position will irradiate near the outlet of the reflective cup body 3, thereby increasing the irradiation area.
[0048] The slider 64 and the fixed shaft 63 are made of translucent glass, and the outer wall of the reflector 8 is coated with a reflective coating, so that when the light is emitted by the LED lamp, the slider 64 and the fixed shaft 63 are prevented from absorbing or blocking the light. At the same time, when the light is irradiated between the reflector 8 and the reflective cup body 3, it is reflected by the reflective coating on the outer wall of the reflector 8 to avoid weakening the light and affecting the lighting effect of the LED lamp.
[0049] When lighting is needed, the staff controls the on-off of the spotlight LED lamp through the switch. At this time, if it is necessary to adjust the light to a long distance, the staff turns the lever 5 at the housing 1, and the lever 5 drives the rotating ring 4 to rotate. During the rotation of the rotating ring 4, the fixed shaft 63 on the slide groove 62 is synchronously driven to rotate, but the fixed shaft 63 is restricted by the movable groove 65 on the fixed ring 61, and can only move obliquely along the movable groove 65, thereby driving the slider 64 to move horizontally relative to the slide groove 62, thereby increasing the light emitting diameter at the LED lamp and improving the brightness of the light;
[0050] When the slider 64 moves laterally, the fixed shaft 63 pushes the wedge block 73 to move along the movable groove 65, and then gradually squeezes the movable rod 72. When the wedge block 73 moves along the movable groove 65 and squeezes the movable rod 72, the wedge block 73 can give the movable rod 72 a force corresponding to the downward force of the reflector 8. Under the cooperation of the wedge block 73 and the wedge surface on the movable rod 72, the movable rod 72 on the reflector 8 is gradually pressed down, and then the reflector 8 is driven to rotate around the mounting frame 71 as a whole, and gradually forms a gathered reflective cup, which reduces the diameter of the light emission end and improves the brightness and distance of the light irradiation.
[0051] When it is necessary to adjust back to the initial position, the lever 5 is returned to the correct position. At this time, the torsion spring 74 will drive the reflector 8 to reset, and then the reflector 8 will form a dispersed state again. At this time, the reset of the lever 5 will drive the slider 64 to reset synchronously, and then the wedge block 73 will reset. At this time, the light of the LED lamp is blocked by the slider 64, thereby reducing the brightness of the light. At the same time, the light emitted by the LED lamp is blocked by the focusing mirror 641, and a part of it will be reflected to the lamp holder 2, and the other part will be reflected on the surface of the focusing mirror 641 to the top of the slider 64, which will increase the irradiation area of the light above the slider 64. The focusing mirror 641 and the reflector 821 will transmit the light outward along the edge of the reflective cup body 3, thereby cooperating with the reflective cup body 3 to increase the irradiation area of the light.
[0052] The basic principles and beneficial effects of the present invention are shown and described above. At the same time, the present invention is not limited to the above embodiments. Without departing from the effects and scope of the present invention, the present invention may have various changes and improvements. These changes and improvements all fall within the scope of the present invention to be protected.
