Description

Technical Field

[0001] The present invention relates to the technical field of lighting fixtures, and in particular to a spotlight LED lamp with a built-in reflector 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. Through the special design of the reflector cup, the light emitted by the LED is focused and reflected, thereby achieving a spotlight effect. Such lamps are usually used in scenarios that require a combination of high brightness and long-distance illumination, such as outdoor lighting.

[0003] During the process of film and television shooting, spotlight LED lamps are often used for large-area lighting and special lighting in special effects shooting. They can flexibly adjust the position of the light under the control of the photographer to meet complex shooting requirements. In addition, the spotlight can also cooperate with other lights to create special light and shadow effects, such as beams passing through clouds, twinkling stars, etc., adding visual beauty to film and television works. However, when switching the mode of the spotlight LED lamp, since the illumination of the LED lamp is divergent, it is necessary to increase the reflector cup to improve the brightness and irradiation distance. However, due to the influence of the fixed curvature of the reflector cup, the light source formed by the laser LED lamp is consistent, and it is difficult to adjust the irradiation distance of the laser LED lamp.

[0004] The prior art often uses multiple spotlight LED lamps for lighting. When long-distance lighting is required, the spotlight LED lamp with a large reflector cup curvature is turned on, or a spotlight LED lamp with a narrow outlet is used. When short-distance lighting is required, the previous spotlight LED lamp is turned off, and the spotlight LED lamp with a small reflector 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 requires controlling multiple spotlight LED lamps synchronously. At the same time, multiple spotlight LED lamps will cause waste of resources, and the adjustment of the irradiation distance and brightness is fixed, making it inconvenient to adjust 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 film and television shooting, the present invention designs a spotlight LED lamp with a built-in reflector cup. Summary of the Invention

[0006] A spotlight LED lamp with a built-in reflector cup provided by the present invention solves 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 film and television shooting. By changing the convergence and divergence of the LED light at the lamp base, the brightness range of the spotlight LED lamp is adjusted. At the same time, by means of the principle of rotation and opening / closing, the irradiation distance and irradiation area of the emitted light are adjusted, thereby improving the controllability of the brightness and irradiation distance of a single spotlight LED lamp during film and television shooting.

[0007] To achieve the above object, the present invention provides the following technical solutions:

[0008] A spotlight LED lamp with a built-in reflector cup provided by the present invention includes a housing, a lamp base, a reflector cup body, a rotating ring, a lever, a driving mechanism, an adjusting mechanism, and a reflector. The lamp base is installed inside the housing, the reflector cup body is installed at the front end of the lamp base, the rotating ring is installed at the front end of the lamp base, the lever is located on the side of the rotating ring and penetrates 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 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 base, and the adjusting mechanism drives the reflector to change the angle of light diffuse reflection;

[0009] By driving the driving mechanism with the lever, the driving mechanism changes the position of the reflector through the adjusting mechanism. Then, the bottom of the reflector fits with the base, and the light will only flow inside the reflector. At the same time, the reflector has been folded at this time, and it gradually forms a converging shape from a dispersed shape. When moving to the extreme position, the free ends of the reflector form a tightly fitting circle with each other. Then, the light will only flow inside the reflector. At this time, the reflector cup formed by the reflector has a smaller outlet diameter than the outlet of the reflector cup body, and the range of the light emitted is smaller, but the focusing distance is farther. At the same time, the driving mechanism also gradually opens the number of bulbs blocking the lamp at the lamp base, so that the bulbs can be directly emitted without reflection, thereby increasing the brightness of the emitted light.

[0010] Preferably, the driving mechanism includes a fixed ring, a sliding groove, a fixed shaft, a slider, and a movable groove. The fixed ring is installed on the housing, the sliding groove is opened on the upper surface of the rotating ring, the fixed shaft slides in the sliding groove, the slider is installed above the rotating ring, the number of sliders is six, the slider is penetrated by the fixed shaft, the movable groove is opened on the fixed ring, and the top of the fixed shaft is installed to slide in the movable groove;

[0011] Adopting the principle of rotation and opening / closing, the aperture formed between the sliders gradually increases, improving the brightness of the light.

[0012] Preferably, the adjusting mechanism includes a mounting bracket, a movable rod, a wedge block, and a torsion spring. The mounting bracket is installed between the lamp holder and the housing. The reflector is installed on the mounting bracket. The movable rod is installed on the reflector, and the top of the movable rod is a wedge surface. The wedge block is installed above the fixed shaft. The bottom surface of the wedge block is adjacent to the wedge surface of the movable rod. The torsion spring is installed between the reflector and the mounting bracket;

[0013] A gear-rack method can also be adopted here. During the movement of the slider, a rack is added to the upper surface of the slider, and 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 requirements of the gear-rack are relatively high, and it will cause a greater obstruction to the light when transmitting inside. However, the structure of the wedge block and the movable rod here is more flexible. Under the cooperation of the wedge block and the upper wedge surface of the movable rod, the whole reflector can be driven to rotate around the mounting bracket, gradually forming a converging reflector cup, reducing the light-emitting aperture, and improving the brightness and distance of the light irradiation.

[0014] Preferably, the reflector is divided into a converging part and a diverging part. The inner surface of the reflector is arc-shaped. A reflector is installed on the back of the diverging part. In the initial state, the top of the reflector is located in the middle of the reflector cup body. The converging part is at the front end of the mounting bracket and is used to concentrate the light irradiation in the converging state. The diverging part is at the rear end of the mounting bracket. When the reflector is in the initial state, the diverging 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 irradiate 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 irregular. In the initial state, the tops of multiple sliders form a circular hole. The thickness value of the slider gradually decreases from the bottom to the top. A focusing lens is installed on the side of the slider facing the lamp holder. In the initial state here, the tops of multiple sliders can also be directly closed, but in this case, another hole needs to be opened on the fixed plate, and the light source directly irradiates the focusing lens through the other hole. At this time, it is necessary to set the thickness value of the slider to gradually increase from the bottom to the top. Then, under the influence of the focusing lens, the light source will directly flow out between the reflector and the reflector cup body, thereby increasing the irradiation range.

[0016] Preferably, baffles with the same curvature are installed on the edges of the reflectors. When in the converging state, the baffles are attached to the edges of adjacent reflectors. The baffles here are used to fill the gaps between the reflectors when the reflectors converge, preventing there from being gaps between the reflectors when they converge.

[0017] Preferably, the reflecting cup body is hyperbolic. In the initial state, the top end of the reflecting plate is located at the central position of the reflecting cup body along the light irradiation direction. This gives the second style of the reflecting cup body. At this time, the reflecting cup body is hyperbolic. Then, when the reflecting plate is in a dispersed state, the light travels along the inner wall of the reflecting cup body to the central position of the reflecting cup, and a new reflecting cup is formed at the front end of the central position of the reflecting cup body, further expanding the irradiation range.

[0018] Preferably, the slider and the fixed shaft are made of light-transmitting glass, and the outer wall of the reflecting plate is coated with a reflective coating. Through the reflection of the reflective coating on the outer wall of the reflecting plate, the weakening of light is avoided.

[0019] The beneficial effects of the present invention are as follows:

[0020] 1. For a spotlight LED lamp with a built-in reflecting cup proposed by the present invention, when it is necessary to increase the lighting distance, at this time, the driving mechanism is driven by the lever. The driving mechanism changes the position of the reflecting plate through the adjusting mechanism. Then, the bottom of the reflecting plate fits with the base, and the light will only flow through the reflecting plate. At the same time, the reflecting plate has been folded at this time, and thus gradually forms a converging shape from a dispersed state. When moving to the extreme position, the free ends of the reflecting plate form a tightly fitting circle with each other. Then, the light will only flow through the reflecting plate. At this time, the reflecting cup formed by the reflecting plate has a smaller outlet diameter than the outlet diameter of the reflecting cup body, and the range of the light emitted is smaller, but the focusing distance is farther. At the same time, the driving mechanism gradually opens the number of bulbs blocked at the lamp base, so that the bulbs can emit light directly without reflection, thereby increasing the brightness and irradiation distance of the emitted light.

[0021] 2. For a spotlight LED lamp with a built-in reflecting cup proposed by the present invention, under the action of the lever, the aperture formed by driving the slider will gradually increase. At the same time, the slider will also slide horizontally in the chute. The mounting bracket is circular, and the cross-sectional shape of the mounting bracket is circular. Then, the reflecting plate can rotate around the mounting bracket. When the slider moves horizontally, the fixed shaft will push the wedge block to move along the direction of the movable groove, and then gradually squeeze the movable rod, thereby driving the whole reflecting plate to rotate around the mounting bracket, gradually forming a converging reflecting cup, reducing the aperture of the light emission, and increasing the brightness and distance of the light irradiation.

[0022] 3. A spotlight LED lamp with a built-in reflector cup proposed by the present invention. The concentrating part is the front end of the mounting bracket, which is used to concentrate the light during the converging state, thereby reducing the aperture of the reflector cup formed by the reflector, further weakening the dispersion of the light, increasing the light brightness and irradiation distance, and reducing the irradiation range. The dispersing part is the rear end of the mounting bracket. When the reflector is in the initial state, the dispersing part will reflect the light through the reflector on its back, and then the light will be reflected by the reflector to the space between the reflector and the reflector cup body. At this time, part of the light will irradiate outward from the edge of the reflector cup body, thereby increasing the irradiation range of the light. In addition, the light irradiating outward along the edge of the reflector cup body will form relatively parallel soft light, improving the irradiation effect at close range. After the reflector is folded, at this time the dispersing part is in contact with the lamp base, so that the light will not flow out through the gap between the reflector and the reflector cup body, increasing the light brightness and the concentrated irradiation effect, and further increasing the irradiation distance of the light.

Detailed implementation manner

[0033] To better understand the above solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings of the specification and the specific implementation manner.

[0034] As Figure 1-2 shown, it includes a housing 1, a lamp holder 2, a reflector body 3, a rotating ring 4, a lever 5, a driving mechanism 6, an adjusting mechanism 7, and a reflector 8. The lamp holder 2 is installed inside the housing 1. The lever 5 is located on the side of the rotating ring 4 and penetrates the housing 1. The rotating ring 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 at the lever 5 to fix the position of the reflector 8 before and after adjustment. If it is fixed, that is, fixed on the ground, wall or other placement objects, at this time, the lever 5 here can be driven by a motor and a set of gear sets. Just keep the need to start the lever 5, drive the gear set to rotate through the motor, and the gear set drives the lever 5 to rotate through the transmission ratio, so as to realize the adjustment of the light.

[0035] The reflector body 3 is installed at the front end of the lamp holder 2. The reflector body 3 is used to gather light. There are various ways to select the reflector body 3 here. Since the irradiation range and irradiation brightness of the light can be adjusted in this application, the reflector body 3 is set to be parabolic or hyperbolic here, so as to increase the irradiation area when the light shoots out of the reflector body 3, and at the same time, the curvature of the reflector body 3 can be used to change the focusing position of the emitted light, so as to control the emission distance of the emitted light after being reflected by the reflector; the driving mechanism 6 is located on the rotating ring 4, the adjusting mechanism 7 is installed between the reflector body 3 and the rotating ring 4, and the reflector 8 is installed at the reflector 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 the light diffuse reflection.

[0036] As Figure 7As shown, under normal circumstances, the reflector 8 is in the unfolded state. At this time, the light at the lamp holder 2 is blocked by the driving mechanism 6 and gradually focused on the circular hole formed by the slider 64. Subsequently, through the refraction of the reflector cup, the focusing effect of the light is improved. Since the opening and curvature of the reflector cup are fixed, the area and luminous distance of the emitted light are also fixed. At the same time, the light is transmitted outward through the position between the reflector 8 and the reflector cup body 3, and thus the light is transported outward along the side wall of the reflector cup, further increasing the irradiation area of the light.

[0037] When it is necessary to increase the lighting distance, at this time, the driving mechanism 6 is driven by the lever 5. The driving mechanism 6 changes the position of the reflector 8 through the adjusting mechanism 7. As a result, the bottom of the reflector 8 is in contact with the base, and the light will only flow inside the reflector 8. At the same time, the reflector 8 has been folded at this time, and thus gradually changes from a dispersed state to a converged state. When it moves to the extreme position, the free ends of the reflector 8 form a tightly fitting circle with each other. As a result, the light will only flow inside the reflector 8. At this time, the reflector cup formed by the reflector 8 has a smaller outlet diameter compared to the reflector cup body 3, and the range of the emitted light is smaller, but the focusing distance is farther. At the same time, the driving mechanism 6 also gradually opens the number of bulbs blocked at the lamp holder 2, so that the bulbs can emit light directly without reflection, thereby increasing the brightness of the emitted light.

[0038] As Figures 3-6 shown, the driving mechanism 6 includes a fixed ring 61, a sliding 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 sliding groove 62 is opened on the upper surface of the rotating ring 4. The fixed shaft 63 slides in the sliding groove 62. 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. The top of the fixed shaft 63 is installed to slide in the movable groove 65.

[0039] The driving mechanism 6 here adopts the principle of rotational opening and closing. With the fixed ring 61 remaining unchanged, the rotating ring 4 is driven to rotate by the lever 5. During the rotation of the rotating ring 4, the fixed shaft 63 on the sliding 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 thus can only move obliquely along the movable groove 65, thereby driving the slider 64 to move horizontally relative to the sliding groove 62. At this time, the aperture formed between the sliders 64 gradually increases, increasing the brightness of the light.

[0040] The adjusting mechanism 7 includes a mounting bracket 71, a movable rod 72, a wedge block 73, and a torsion spring 74. The mounting bracket 71 is installed between the lamp base 2 and the housing 1. The reflector 8 is installed on the mounting bracket 71. The movable rod 72 is installed on the reflector 8, and the top of the movable rod 72 is a wedge 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. The torsion spring 74 is installed between the reflector 8 and the mounting bracket 71.

[0041] The adjusting mechanism 7 here adopts the principle of wedge-shaped cooperation. As described above, under the action of the lever 5, the aperture formed by driving the slider 64 will gradually increase. At the same time, the slider 64 will also slide horizontally in the chute 62. The mounting bracket 71 is circular, and the cross-sectional shape of the mounting bracket 71 is circular. Thus, the reflector 8 can rotate around the mounting bracket 71. When the slider 64 moves horizontally, the fixed shaft 63 will push the wedge block 73 to move along the direction of the movable groove 65, and then gradually squeeze the movable rod 72. The movable rod 72 is located on the reflector 8. Although the moving direction of the wedge block 73 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 a downward component force of the movable rod 72 corresponding to the reflector 8. Under the cooperation of the wedge surface on the wedge block 73 and the movable rod 72, the movable rod 72 on the reflector 8 is gradually pressed down at this time, and then drives the whole reflector 8 to rotate around the mounting bracket 71, gradually forming a converging reflector cup, reducing the aperture of light emission, and improving the brightness and distance of light irradiation.

[0042] As Figures 7-8 shown, the reflector 8 is divided into a converging part 81 and a diverging part 82. The inner surface of the reflector 8 is arc-shaped; a reflecting mirror 821 is installed on the back of the diverging part 82. In the initial state, the top end of the reflector 8 is located in the middle of the reflector cup body 3 and does not fit with the reflector cup body 3.

[0043] The converging part 81 is the front end of the mounting bracket 71 and is used to concentrate the light irradiation in the converged state, thereby reducing the aperture of the reflector cup formed by the reflector 8, further weakening the dispersion of the light, increasing the light brightness and irradiation distance, and reducing the irradiation range. The diverging part 82 is the rear end of the mounting bracket 71. When the reflector 8 is in the initial state, the diverging 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 irradiate outward from the edge of the reflector cup body 3, thereby increasing the irradiation range of the light. In addition, the light irradiating outward along the edge of the reflector cup body 3 will form relatively parallel soft light, improving the irradiation effect at close range. After the reflector 8 is folded, at this time the diverging part 82 is in contact with the lamp base 2, so that the light will not flow out from the gap between the reflector 8 and the reflector cup body 3, increasing the light brightness and the converging irradiation effect, and further 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 multiple sliders 64 form a circular hole. The thickness value of the slider 64 gradually decreases from the bottom to the top. A focusing lens 641 is installed on the side of the slider 64 facing the lamp base 2. During the gradual sliding of the slider 64, at this time the circular hole at the top of the slider 64 is damaged, but the area formed by the front edge of the slider 64 is gradually increasing, and thus more and more exposed LED lights are exposed. At this time, the light concentration of the LED lights is concentrated by the reflector 8. On the contrary, initially, the light emitted by the LED lights is blocked by the focusing lens 641. Part of it will be reflected to the lamp base 2, and the other part will be reflected on the surface of the focusing lens 641 to above the slider 64, increasing the irradiation area of the light above the slider 64. On the one hand, it weakens the light brightness, and on the other hand, it makes the light be reflected by the reflector 821, enabling the light to 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, at this time the reflector 8 will not form a completely enclosed space with the reflector cup, and thus will not affect the normal focusing of the reflector cup body 3 on the light. That is, while the reflector cup body 3 focuses the light, the focusing lens 641 and the reflector 821 will transmit the light outward along the edge of the reflector cup body 3, increasing the irradiation area of the light source of the reflector cup body 3 and weakening the brightness of the light source under long-distance action, avoiding the problem of dazzling and discomfort to the human body.

[0045] A baffle 83 with the same curvature is installed at the edge of the reflector 8. When in the converged state, the baffle 83 is in contact with the edge of the adjacent reflector 8. The baffle 83 here is used to fill the gap between the reflectors 8 when the reflectors 8 are converged, preventing there from being a gap between the reflectors 8 when they are converged, thereby causing light to leak from inside the reflector 8 to between the reflector 8 and the reflector 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, turn the return lever 5 back. At this time, the torsion spring 74 will drive the reflector 8 to reset. Furthermore, the reflector 8 will return to the dispersed state. At this time, the reset of the lever 5 will drive the slider 64 to reset synchronously, and then the wedge block 73 will be 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 lens 641. A part of the light will be reflected to the lamp holder 2, and the other part will be reflected on the surface of the focusing lens 641 to above the slider 64, which will increase the irradiation area of the light above the slider 64. The focusing lens 641 and the reflecting mirror 821 will transmit the light along the edge of the reflector body 3 outward, thereby cooperating with the reflector body 3 to increase the irradiation area of the light.

[0052] The above shows and describes the basic principles and beneficial effects of the present invention. At the same time, the present invention is not limited by the above embodiments. Without departing from the effects and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed. The scope of the present invention claimed is defined by the appended claims and their equivalents.
