[0003] LED lamps often require the addition of lenses or reflectors to alter the scattering angle of the LED's light to meet operational requirements. This process is commonly known in the industry as "light distribution" or "secondary optical processing." When the LED light source emits multiple colors, this light must also be mixed. However, some lamps suffer from uneven light mixing or the inability to adjust the light distribution angle, making it impossible to achieve both light mixing and light distribution requirements.

[0004] In view of this, it is indeed necessary to improve the existing lamps to solve the above problems. Summary of the Invention

[0035] In order to make the objectives, technical solutions and advantages of this application clearer, this application is described in detail below with reference to the accompanying drawings and specific embodiments.

[0036] Referring to Figures 1 and 2 , this application discloses a light-mixing lamp 100 with controllable light distribution angle, comprising a housing 1, a light source assembly 2, a reflector assembly 3, and a fixing member 4. This light-mixing lamp 100 with controllable light distribution angle not only achieves a uniform light mixing effect but also allows for secondary adjustment of the light source illumination angle to meet both light mixing and light distribution requirements.

[0037] As shown in Figures 2 to 7, the shell 1 is provided with an installation space 11 and an installation opening 12 passing through the installation space 11; the light source assembly 2 is located in the installation space 11 and fixed on the shell 1; the reflector assembly 3 is located in the installation space 11 and connected to the light source assembly 2, and the reflector assembly 3 is also connected to the shell 1 and exposed at the installation opening 12; the fixing member 4 is arranged on the inner circumferential wall of the shell 1.

[0038] Specifically, the housing 1 includes a first housing 13 and a second housing 14, wherein the second housing 14 is configured to be rotatably connected to the first housing 13. A hanging plate 131 is provided on the side of the first housing 13 facing the second housing 14, and a corresponding stopper 141 is provided on the inner sidewall of the second housing 14. The hanging plate 131 is screwed into the stopper 141, thereby fixedly connecting the first housing 13 and the second housing 14. A positioning member 132 is also provided at the end of the hanging plate 131 to limit the hanging plate 131 and the stopper 141 after the hanging plate 131 is screwed into the stopper 141, thereby preventing the second housing 14 from falling off one end of the first housing 13 during use of the mixed-light lamp 100 with controllable light distribution angle.

[0039] The light source assembly 2 is fixed within the first housing 13, and the fixing member 4 is threadedly connected to the first housing 13. The reflector assembly 3 includes a first reflector 31, a second reflector 32, and a frosted plate 33 located between the first reflector 31 and the second reflector 32. The outer peripheral edge of the frosted plate 33 is fixedly connected to the fixing member 4. Specifically, the frosted plate 33 is clamped within the fixing member 4 to securely mount the frosted plate 33 within the first housing 13. One end of the first reflector 31 is connected to the light source assembly 2, and the other end is connected to the frosted plate 33, forming a light mixing cavity 310 between the frosted plate 33 and the first reflector 31. In other words, the light mixing cavity 310 is located within the first housing 13. A limiting frame 5 is further provided in the first shell 13, and the limiting frame 5 has a limiting opening 51. The light source assembly 2 is accommodated inside the limiting frame 5 and partially exposed to the limiting opening 51. The first reflector cup 31 is inserted into the limiting opening 51 and contacts the light source assembly 2. The limiting frame 5 not only limits the light source assembly 2 on the first shell 13, but also further limits the first reflector cup 31 to prevent the first reflector cup 31 from moving, which would cause the light emitted by the light source assembly 2 to be unable to completely enter the mixing cavity 310.

[0040] The second reflector 32 is fixedly connected to the second housing 14 and exposed at the mounting opening 12. Specifically, the second reflector 32 is partially housed within the first housing 13, and the mounting opening 12 is formed on the second housing 14. An abutment (not numbered) is provided around the inner side of the mounting opening 12. The second reflector 32 is magnetically connected to the second housing 14 and is secured to the abutment, thereby achieving a fixed connection between the second reflector 32 and the second housing 14. In other embodiments, a hook may be provided on the outer wall of the second reflector 32, and the second reflector 32 and the second housing 14 may be configured to be rotatably connected. As long as the second reflector 32 and the second housing 14 are fixedly connected, this is not a limitation.

[0041] The frosted plate 33 is a light-transmitting plate. The light source assembly 2 is configured to emit multi-color light. This multi-color light undergoes mixing and initial distribution within the light mixing cavity 310 before entering the second reflector cup 32 for secondary light distribution angle adjustment. It will be appreciated that both the first reflector cup 31 and the frosted plate 33 independently perform light mixing and distribution functions, ensuring more uniform mixing of the multi-color light within the light mixing cavity 310. The second reflector cup 32 is spaced apart from the frosted plate 33. In another embodiment, the second reflector cup 32 and the frosted plate 33 can also be in contact with each other, as long as the second angle adjustment of the light is achieved. The second reflector cup 32 performs secondary angle adjustment, thereby achieving a controllable light mixing effect.

[0042] As shown in Figures 8-13 , in this application, the frosted plate 33 can be injection-molded from different PC materials. By varying the injection-molded material of the frosted plate 33 , it is possible to achieve light distribution at different angles and uniform multi-color light mixing. The following examples illustrate three specific materials for the frosted plate 33 , but are not intended to be limiting.

[0043] In the first embodiment, when the injection molding material of the frosted plate 33 is transparent PC, the beam angle of the entire lamp is approximately 25 degrees.

[0044] In the second embodiment, when the injection molding material of the frosted plate 33 is diffused PC material 1, the beam angle of the entire lamp is approximately 38 degrees.

[0045] In the third embodiment, when the injection molding material of the frosted plate 33 is diffused PC material 2, the beam angle of the entire lamp is approximately 50 degrees.

[0046] It should be noted that the first and second diffusion PC materials are obtained by adding diffusing surface particles to a transparent PC. Adjusting the concentration ratio of the surface particles can control the haze of the diffusion PC materials. In other words, the first and second diffusion PC materials are translucent, opaque light-diffusing materials. The first diffusion PC material can be Bayer 021069, and the second diffusion PC material can be Teijin 3107, without limitation.

[0047] In this embodiment, both the first reflector 31 and the second reflector 32 are conical cups that are transparent from top to bottom. Preferably, the inner diameter of the second reflector 32 in any plane is larger than the inner diameter of the first reflector 31 in any plane. The end of the first reflector 31 with the largest inner diameter faces the frosted plate 33, while the end of the second reflector 32 with the smallest inner diameter faces the frosted plate 33. This ensures that all light emitted from the light mixing cavity 310 is incident upon the second reflector 32 for secondary angle adjustment.

[0048] In summary, the present application disposes the reflector assembly 3 within the mounting space 11 of the housing 1 and connects it to the light source assembly 2. The reflector assembly 3 includes a first reflector 31, a second reflector 32, and a frosted plate 33 located between the first reflector 31 and the second reflector 32. The outer edge of the frosted plate 33 is fixedly connected to the fixing member 4, so that one end of the first reflector 31 is connected to the light source assembly 2 and the other end is connected to the frosted plate 33, thereby forming a light mixing cavity 310 between the frosted plate 33 and the first reflector 31. Meanwhile, the second reflector 32 is fixedly connected to the housing 1 and exposed at the mounting opening 12. Compared to the prior art, the present invention's light-mixing lamp 100 with controllable light distribution angle can not only achieve a uniform light mixing optical effect, but also perform secondary angle adjustment of the light source illumination to meet both light mixing requirements and light distribution requirements.

[0049] The above embodiments are only used to illustrate the technical solutions of the present application and are not intended to limit the present application. Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present application.
