Description

Technical Field

[0001] The utility model relates to the technical field of movie and television lamp light sources, in particular to a 1200W movie and television lamp dual-color light source. Background Art

[0002] Cinema lights are artificial light sources for videography. When the ambient light is too low, cameras must use equipment. COB cinema lights are cinema lights that use COB light sources. COB light sources are high-efficiency integrated surface light source technology that directly attaches LED chips to a high-reflectivity mirror metal substrate. This technology eliminates the concept of brackets, and there is no electroplating, no reflow soldering, and no patch process. Therefore, the process is reduced by nearly one-third, and the cost is also saved by one-third.

[0003] The existing COB light source uses an aluminum nitride ceramic bracket, which is resistant to high pressure and has high thermal conductivity, so that the 1200W movie light source has a good heat dissipation effect. By dotting high-color rendering phosphors of corresponding colors on the chip, the 1200W movie light dual-color light source can emit two different colors of light, and the mixed light effect is good.

[0004] However, during the implementation of the above technical solution, it was found that at least the following problems exist:

[0005] During the installation of the light source, the light source body needs to be installed on the outside of the radiator through the fixing screws at both ends of the mounting frame. During the installation process, when the staff turns the fixing screws on one side to make the fixing screw thread connected to the connection port opened in the radiator, the mounting frame is easy to move, resulting in the fixing screws on this side being unable to be aligned with the corresponding connection port after the fixing screws on the other side are fixed. At this time, the staff needs to release the fixing screws and reinstall them, which reduces the convenience of the installation process. Utility Model Content

At this time, the staff needs to release the fixing screw 4 and reinstall it, which reduces the convenience of the installation process.

[0028] Example

[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The technical solution in the embodiment of the present application effectively solves the problem that during the installation process, when the staff rotates the fixing screw 4 on one side to make the fixing screw 4 threadedly connected to the connection port opened by the radiator 2, the mounting frame 3 is easy to move, resulting in the fixing screw 4 on this side being unable to align with the corresponding connection port after the fixing screw 4 on this side is fixed. At this time, the staff needs to release the fixing screw 4 and reinstall it, which reduces the convenience of the installation process. The overall idea is as follows:

[0030] In view of the problems existing in the prior art, the utility model provides a 1200W film and television lamp dual-color light source, which comprises a light source body 1, a radiator 2, a mounting frame 3, fixing screws 4 and a protective cover 5. The light source body 1 is placed on the upper surface of the radiator 2, the mounting frame 3 is placed outside the light source body 1, two fixing screws 4 are movably connected to the two ends of the mounting frame 3, two fixing screws 4 are respectively threadedly connected to the two ends of the radiator 2, the protective cover 5 is arranged outside the radiator 2, the mounting frame 3 is located between the protective cover 5 and the radiator 2, and a limiting mechanism is arranged outside the radiator 2;

[0031] The limiting mechanism includes a limiting hole 6, a limiting block 7, a limiting cylinder 8 and a through hole 9;

[0032] There are two limiting holes 6, both of which are provided on the outside of the radiator 2, there are two limiting blocks 7, both of which are fixedly mounted on one side of the mounting frame 3 close to the radiator 2, there are two limiting tubes 8, both of which are fixedly mounted on one side of the protective cover 5 close to the mounting frame 3, the through hole 9 is provided on the outside of the protective cover 5, and the light source body 1 is located on the inner side of the through hole 9;

[0033] The limiting block 7 is slidably connected to the inside of the limiting hole 6 , and the two fixing screws 4 are slidably connected to the inner sides of the two limiting tubes 8 .

[0034] By setting the limit block 7 and cooperating with the limit tube 8, the light source body 1 is fitted to the outside of the radiator 2. At this time, the mounting bracket 3 is placed on the outside of the light source body 1. At this time, due to the existence of the limit block 7 and the limit hole 6, during the placement of the mounting bracket 3, the limit block 7 is inserted into the inside of the limit hole 6. At this time, the position of the mounting bracket 3 is fixed. At this time, the fixing screw 4 is rotated to make the fixing screw 4 and the radiator 2 be threadedly connected to fix the mounting bracket 3. At this time, the protective cover 5 is placed on the outside of the radiator 2 to cover the mounting bracket 3. At this time, the fixing screw 4 enters the inner side of the limit tube 8 away from one end of the radiator 2 and fits the inner wall of the limit tube 8, thereby limiting the rotation of the fixing screw 4. By limiting the position of the mounting bracket 3, the mounting bracket 3 does not move when the fixing screw 4 on one side is connected to the radiator 2, thereby avoiding the situation that the fixing screw 4 on the other side cannot be aligned with the connecting port of the radiator 2 after the fixing screw 4 on one side is fixed, thereby improving the convenience of installation while increasing the stability of the connection of the fixing screw 4.

[0035] A limiting groove 10 is provided at one end of the protective cover 5 close to each limiting cylinder 8, and a limiting plate 11 is provided at both ends of the radiator 2;

[0036] The limiting plate 11 is slidably connected to the inside of the limiting groove 10 , so that the fixing screw 4 can directly enter the inner side of the limiting tube 8 , without the need for the staff to adjust the position of the protective cover 5 multiple times.

[0037] A threaded rod 12 is fixedly mounted on the outside of each limiting plate 11, and a threaded cap 13 is threadedly connected to the outside of the threaded rod 12;

[0038] The threaded cap 13 fits the upper surface of the protective cover 5 to facilitate fixing the protective cover 5 .

[0039] A protective cover 14 is provided outside the protective cover 5;

[0040] The protective cover 14 is located above the through hole 9. When the protective cover 5 is installed, the protective cover 14 covers the lamp beads to protect the lamp beads.

[0041] The outside of the protective cover 5 is provided with a mounting hole 15;

[0042] The protective cover 14 is clamped inside the mounting hole 15 , which facilitates the disassembly and assembly of the protective cover 14 .

[0043] A protective pad 16 is fixedly mounted on one side of the protective cover 14 close to the protective cover 5;

[0044] The protection pad 16 is made of silicone material to increase the stability of the connection between the protection cover 14 and the mounting hole 15 .

[0045] By setting the threaded cap 13 and cooperating with the limit plate 11, when installing the protective cover 5, the protective cover 5 is slidably connected to the outside of the limit plate 11 through the limit groove 10, so that the fixing screw 4 can directly enter the inner side of the limit tube 8, and the staff does not need to adjust the position of the protective cover 5 many times. At this time, the threaded cap 13 is threadedly connected to the outside of the threaded rod 12. At this time, the protective cover 5 is installed. When removing the protective cover 5, the threaded cap 13 is rotated to release the connection between the threaded cap 13 and the threaded rod 12, and the protective cover 5 is pulled upward to release the connection between the limit plate 11 and the limit groove 10. At this time, the protective cover 5 is removed. The disassembly and assembly of the protective cover 5 is simple, which is convenient for the staff to operate and reduces the difficulty of operation for the staff.

[0046] Working principle:

[0047] By setting the limiting block 7 and cooperating with the limiting cylinder 8, the light source body 1 is fitted to the outside of the radiator 2. At this time, the mounting bracket 3 is placed on the outside of the light source body 1. At this time, due to the existence of the limiting block 7 and the limiting hole 6, during the process of placing the mounting bracket 3, the limiting block 7 is inserted into the inside of the limiting hole 6. At this time, the position of the mounting bracket 3 is fixed. At this time, the fixing screw 4 is rotated to make the fixing screw 4 and the radiator 2 be threadedly connected to fix the mounting bracket 3. At this time, the protective cover 5 is placed on the outside of the radiator 2 to cover the mounting bracket 3. At this time, the fixing screw 4 away from the end of the radiator 2 enters the inner side of the limiting cylinder 8 and fits the inner wall of the limiting cylinder 8, thereby limiting the rotation of the fixing screw 4 and limiting the position of the mounting bracket 3;

[0048] The fixing screw 4 enters the inner side of the limiting tube 8, and the protective cover 5 is slidably connected to the outside of the limiting plate 11 through the limiting groove 10. At this time, the threaded cap 13 is threadedly connected to the outside of the threaded rod 12, and the protective cover 5 is installed.
