Detailed Implementation
[0025] like Figures 1 to 6 As shown, a photographic fill light includes a fill light body 10. Inside the fill light body 10 are a cooling fan 20, a heat dissipation bracket 30, and a light source assembly 40, arranged sequentially. A driver circuit board 50 is installed at the rear inner part of the fill light body 10. A light source cover 60 is detachably mounted at the front end of the fill light body 10, covering the outside of the light source assembly 40. The light source cover 60 prevents direct contact between the light source assembly 40 and external elements, improving safety. During use, the light emitted by the light source assembly 40 is refracted, diffused, or mixed by the light source cover 60, resulting in more uniform and softer output light, thus improving the fill light effect. The cooling fan 20 generates airflow during operation, which, in conjunction with the structure of the heat dissipation bracket 30, promptly dissipates the heat generated by the light source assembly 40 during operation, improving the heat dissipation efficiency of the light source assembly 40 and extending the overall lifespan of the fill light.
[0026] In practical implementation, the front end of the supplementary lighting body 10 is equipped with a front cover 11. The front cover 11 has a front cover opening 111 in the middle. The inner side of the front cover opening 111 is provided with a plurality of evenly spaced outer cover slots 112. Each of the outer cover slots 112 has a fixing slot 113 on its side. The rear end edge of the light source cover 60 is evenly provided with a plurality of fixing protrusions 61. During installation, the rear end of the light source cover 60 is embedded in the front cover opening 111. Simultaneously, the fixing protrusions... Block 61 slides into several corresponding slots 112 of the outer cover, and by rotating the light source cover 60, the fixing protrusion 61 is correspondingly engaged in the fixing slot 113, thereby allowing the light source cover 60 to be detachably mounted on the front end of the fill light body 10. During use, the snap-fit connection between the front cover 11 of the light body and the light source cover 60 allows users to quickly change light source covers of different specifications and light effects according to the needs of different shooting scenarios, improving the flexibility of the fill light. Furthermore, because the fixing protrusion 61 and the fixing slot 113 form a stable limiting fit, it ensures that the light source cover 60 remains reliably fixed during long-term shooting or when the device is moved, preventing it from easily loosening, further improving the overall safety and stability of the fill light.
[0027] In practical implementation, the light source housing 60 is made of borosilicate glass. Borosilicate glass is characterized by high temperature resistance, impact resistance, high light transmittance, and stable optical performance. It can maintain structural stability even when the light source component 40 generates high heat during long-term operation, and is not easily deformed or cracked. At the same time, the high borosilicate glass material has good optical refraction and diffusion characteristics, which can refract, scatter, and mix the light emitted by the light source component 40, making the light more uniform and softer after passing through the light source housing 60, and avoiding phenomena such as light spots, harsh edges, or color temperature separation.
[0028] In practical implementation, the light source assembly 40 includes a light source panel 41, a reflector 42, a light source lens 43, and a light source fixing ring 44. The light source panel 41 is located at the rear end of the reflector 42, the light source lens 43 is located at the front end of the reflector 42, and the light source fixing ring 44 is sleeved on the front side of the reflector 42, pressing the light source lens 43 to stably fix it at the front end of the reflector 42. In use, the light emitted by the LED light source on the light source panel 41 first enters the interior of the reflector 42, and is reflected and refracted by the arc-shaped inner wall of the reflector 42 to achieve primary light gathering and mixing. Then, the light passes through the light source lens 43 located at the front end, and the light source lens 43 refracts, focuses, or diffuses the light again, making the output light more uniform, softer, and with higher illuminance stability. The light source fixing ring 44 effectively prevents the light source lens 43 from loosening or shifting during shooting or long-term use, thereby ensuring the stability of the optical path output and improving the overall optical performance of the fill light.
[0029] In practical implementation, the reflector cup 42 is an arc-shaped reflective structure. Its inner surface is polished or mirrored, which can effectively reflect the light emitted by the light source panel 41 and converge the light to the front light source lens 43. This arc-shaped design not only increases the refraction and mixing effect of light inside the reflector cup 42, but also enhances the light intensity to a certain extent, making the output light more uniform and soft.
[0030] In practical implementation, the inner surface of the front cover opening 111 is uniformly provided with a plurality of fixing positions 114, and the rear end edge of the light source fixing ring 44 is uniformly provided with a plurality of fixing blocks 441. The plurality of fixing blocks 441 are correspondingly arranged on the plurality of fixing positions 114, and are connected and fixed to the fixing positions 114 by fasteners passing through the fixing blocks 441, thereby making the light source fixing ring 44 firmly fixed to the front end of the supplementary light body 10. Through the above structural setting, the light source fixing ring 44 can reliably press the light source lens 43 and the reflector cup 42 and prevent them from loosening or shifting during use, ensuring that the optical system of the light source assembly 40 always maintains a stable optical path structure.
[0031] In practical implementation, a lamp body rear cover 12 is installed at the rear end of the supplementary light body 10. The lamp body rear cover 12 has a rear cover mounting position 121 inside. The drive circuit board 50 is installed on the rear cover mounting position 121 and fixed by fasteners. The input end of the drive circuit board 50 is electrically connected to the external power interface, and the output end is electrically connected to the light source lamp board 41 of the light source assembly 40, thereby providing a stable drive current and control signal to the light source assembly 40.
[0032] In practical implementation, the upper and lower sides of the supplementary light lamp body 10 are evenly provided with a number of first heat dissipation openings 13, and the upper side of the lamp body rear cover 12 is evenly provided with a number of second heat dissipation openings 122. When the cooling fan 20 is working, it draws air in from the rear end or side of the supplementary light lamp body 10, forms an airflow circulation through the heat dissipation bracket 30 and the light source assembly 40, and then discharges it from the second heat dissipation openings 122 of the lamp body rear cover 12 and the first heat dissipation openings 13 of the supplementary light lamp body 10, thereby achieving effective heat dissipation of the light source assembly 40, the light source lens 43 and the drive circuit board 50.
[0033] In practical implementation, the lower side of the fill light body 10 is provided with a bracket mounting part 14. The lower end of the bracket mounting part 14 is movably connected to a mounting bracket 15. The mounting bracket 15 can be connected to the bracket mounting part 14 through a rotation, folding or locking mechanism, so that the fill light body 10 can be easily fixed on a tripod, camera bracket or other photography equipment. At the same time, the installation angle and height of the fill light can be adjusted to meet the needs of different shooting scenarios.
[0034] In summary, the combination of the light source panel 41, the arc-shaped reflector 42, and the light source lens 43, along with the refraction, diffusion, and light mixing effects of the high borosilicate glass light source cover 60, results in uniform and soft output light without any light spots or color temperature separation. The light source cover 60 isolates the high-voltage light source, preventing direct contact by the user. At the same time, the stable design of the light source fixing ring 44 and the front cover 11 of the lamp body ensures that the optical components will not loosen during movement or long-term use. High heat dissipation efficiency: the cooling fan 20, the heat dissipation bracket 30, and the heat dissipation openings of the supplementary light lamp body 10 and the rear cover 12 of the lamp body form an effective airflow circulation, effectively reducing the temperature of the light source component 40 and the drive circuit board 50, and extending their service life.
