DETAILED DESCRIPTION

[0024] In order to make the purpose, features and beneficial effects of the present invention more obvious and easy to understand, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0025] It should be understood that the described embodiments are only some embodiments of the present invention, rather than all embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0026] The following is a detailed description with reference to the accompanying drawings.

[0027] The embodiment of the present invention provides a lamp, please refer to Figures 1 to 3 , Figure 1 2 is an exploded view of a lamp according to an embodiment of the present invention, 3 is a cross-sectional schematic view of a lamp according to an embodiment of the present invention, Figure 2 In the enlarged view of the middle area A, the lamp includes: a chassis 100, a frame assembly 200, an annular diffuser 400, a first light-emitting assembly 510, a total reflection portion 610 and a partial reflection portion 620, wherein the frame assembly 200 is fixed on the chassis 100, and the frame assembly 200 is formed with an annular first mounting groove 310.

[0028] The annular diffusion cover 400 is located in the first installation groove 310 , and divides the first installation groove 310 into a light mixing area 311 and a reflection area 312 which are adjacent to each other along the radial direction thereof.

[0029] Among them, at least one side of the groove wall surface of the first installation groove 310 is inclined inward, so that the groove opening width of the first installation groove 310 is smaller than the groove bottom width, and the mixing area 311 exposes the inward inclined groove wall surface of the first installation groove 310, and the groove opening of the first installation groove 310 is located in the reflection area 312.

[0030] In addition, the first light emitting component 510 is disposed at the bottom of the light mixing area 311 , the total reflection portion 610 is disposed in the reflection area 312 , and the partial reflection portion 620 is disposed at the notch of the first installation groove 310 .

[0031] Correspondingly, the light emitted by the first light-emitting component 510 is mixed by the light mixing area 311 and then incident on the reflection area 312. Moreover, among the light incident on the reflection area 312, part of it is transmitted through the partial reflection part 620, and part of it is reflected by the partial reflection part 620 to the total reflection part 610 and then reflected to the partial reflection part 620 again.

[0032] Therefore, the light emitted by the first light-emitting component 510 can achieve a deep thousand-layer light-emitting effect.

[0033] Specifically, on the one hand, since the annular diffuser 400 is located in the first mounting groove 310 and divides the first mounting groove 310 into a mixing zone 311 and a reflection zone 312 which are adjacent to each other along the radial direction, on the other hand, the mixing zone 311 exposes the inwardly inclined groove wall of the first mounting groove 310, and the first light-emitting component 510 is arranged at the bottom of the mixing zone 311, therefore, the light emitted by the first light-emitting component 510 can be mixed in the mixing zone 311 and then incident on the adjacent reflection zone 312.

[0034] That is to say, part of the light emitted by the first light-emitting component 510 directly passes through the annular diffuser 400 between the light-mixing zone 311 and the reflection zone 312 and is incident on the adjacent reflection zone 312, while the other part is reflected by the inwardly inclined groove wall of the first mounting groove 310, and then passes through the annular diffuser 400 between the light-mixing zone 311 and the reflection zone 312 and is incident on the adjacent reflection zone 312, thereby achieving the effect that the light emitted by the first light-emitting component 510 is mixed in the light-mixing zone 311 and then incident on the adjacent reflection zone 312.

[0035] On this basis, since the total reflection portion 610 is arranged in the reflection area 312, and the partial reflection portion 620 is arranged at the slot of the first mounting slot 310, part of the light incident to the reflection area 312 can directly pass through the partial reflection portion 620, and the other part is reflected by the partial reflection portion 620 to the total reflection portion 610, and then reflected to the partial reflection portion 620 again.

[0036] It should be understood that, among the light reflected from the total reflection portion 610 to the partial reflection portion 620 , part of it still passes directly through the partial reflection portion 620 , and another part of it is reflected from the partial reflection portion 620 to the total reflection portion 610 and then reflected to the partial reflection portion 620 again.

[0037] In some embodiments, a plurality of annular concave arc surfaces are formed on the light mixing surface, and the plurality of concave arc surfaces are sequentially connected in the extending direction of the inwardly inclined groove wall surface of the first installation groove 310 , thereby further improving the light mixing effect of the light mixing area 311 .

[0038] The light mixing surface is a portion of the inwardly inclined groove wall surface of the first installation groove 310 that is exposed by the light mixing area 311 .

[0039] The type of light fixture is a ceiling light, pendant light or wall light.

[0040] In some embodiments, the chassis 100 has a mounting side 101 and a light emitting side 102 opposite to each other. The mounting side 101 is used to fix the lamp on a mounting base, such as a ceiling, a wall, etc., and the light emitting side 102 is the side of the lamp that emits light.

[0041] Correspondingly, the frame assembly 200 and the first mounting groove 310 are both located on the light emitting side 102 .

[0042] In some embodiments, the annular diffuser 400 includes a diffuser sidewall 410 . The light mixing area 311 and the reflection area 312 are respectively located on both sides of the diffuser sidewall 410 , and the light mixing area 311 is located between the diffuser sidewall 410 and the inwardly inclined groove wall surface of the first installation groove 310 .

[0043] In some embodiments, the frame assembly 200 includes an inner frame 210 and an outer frame 220 , wherein the outer frame 220 is disposed around the inner frame 210 .

[0044] The inner frame 210 is configured with an annular inner wall 211 , and the outer frame 220 is configured with an outer wall 221 .

[0045] The outer wall 221 is disposed around the inner wall 211, and a first mounting groove 310 is formed between the outer wall 221 and the inner wall 211. In addition, the outer wall 221 is inclined toward the first mounting groove 310, so that at least one side of the groove wall of the first mounting groove 310 is inclined inward. Accordingly, the light mixing area 311 is located between the diffuser side wall 410 and the outer wall 221.

[0046] In some embodiments, the side wall surface of the outer side wall 221 facing the first mounting groove 310 includes the aforementioned light mixing surface.

[0047] In some embodiments, the annular diffuser cover 400 further includes a diffuser cover support plate 420 .

[0048] The diffusion cover support plate 420 extends from the diffusion cover side wall 410 in a direction facing away from the light mixing area 311 , and the total reflection portion 610 is fixed on the diffusion cover support plate 420 .

[0049] Furthermore, the annular diffuser cover 400 includes: two diffuser cover side walls 410 .

[0050] The two diffusion cover side walls 410 are respectively located on both sides of the diffusion cover support plate 420 , and the reflection area 312 is located between the two diffusion cover side walls 410 .

[0051] In addition, the inner side wall 211 is also inclined toward the first installation groove 310, so that the groove walls on both sides of the first installation groove 310 are inclined inward, and accordingly, the light mixing area 311 is also located between the diffusion cover side wall 410 and the inner side wall 211. Thus, the deep thousand-layer light effect of the lamp is further improved.

[0052] In some embodiments, the side wall surface of the inner side wall 211 facing the first mounting groove 310 also includes the aforementioned light mixing surface.

[0053] In some embodiments, the inner wall 211 divides the chassis 100 into a main lighting area 110 and an ambient lighting area 120 . The main lighting area 110 and the ambient lighting area 120 are respectively located on two sides of the inner wall 211 , and the ambient lighting area 120 is arranged around the main lighting area 110 .

[0054] Correspondingly, the lamp further includes: a main mask 720 and a main light source module 530 .

[0055] The main mask 720 is fixed to the inner frame 210 and is located above the main lighting area 110 . The main light source module 530 is fixed to the chassis 100 of the main lighting area 110 , and the light emitted by the main light source module 530 is emitted through the main mask 720 .

[0056] Preferably, the periphery of the main mask 720 has a main mask elastic flange 721 extending toward the chassis 100, and the main mask elastic flange 721 abuts against the side of the inner wall 211 facing the main lighting area 110. Since the inner wall 211 is also inclined toward the first mounting groove 310, and the main mask elastic flange 721 abuts against the side of the inner wall 211 facing the main lighting area 110, therefore, on the basis of forming the light mixing area 311 by the inner wall 211, not only can the main mask 720 and the inner frame 210 be fixedly connected by the main mask elastic flange 721 abutting against the inner wall 211 to form a closed main lighting cavity, but also the abutting position of the main mask elastic flange 721 and the inner wall 211 will be hidden behind the main mask 720, so that it is not only conducive to realizing a narrow frame matching structure with a simple structure, but also the matching structure can be seamlessly matched, which is conducive to realizing a line light lighting effect without light leakage.

[0057] In other embodiments, the inner wall 211 divides the chassis 100 into a dark area and an ambient lighting area 120 . The dark area and the ambient lighting area 120 are respectively located on two sides of the inner wall 211 , and the ambient lighting area 120 is disposed around the dark area.

[0058] In some embodiments, a notch 411 is configured at the bottom of the diffuser cover side wall 410 .

[0059] The notch 411 faces the first light-emitting component 510, and the adjacent sidewalls of the notch 411 are arranged at an obtuse angle. In addition, the diffusion cover support plate 420 is higher than the notch 411. Thus, the light emitted by the first light-emitting component 510 has a light shielding and reflection effect, so that the light is better mixed in the light mixing area 311, avoiding the light effect with light and dark granularity.

[0060] In some embodiments, the top of the inner wall 211 has an inner wall hook 212 protruding toward the outer wall 221 , and the top of the outer wall 221 has an outer wall hook 222 protruding toward the inner wall 211 .

[0061] Correspondingly, the top of the diffusion cover side wall 410 has a diffusion cover top flange 412 extending away from the diffusion cover support plate 420, and the two diffusion cover top flanges 412 are respectively located below the inner wall hook 212 and the outer wall hook 222. Based on this, the two side edges of the partial reflection part 620 are respectively clamped between the inner wall hook 212 and the top flange 412 of the diffusion cover below the inner wall hook 212, and between the outer wall hook 222 and the top flange 412 of the diffusion cover below the outer wall hook 222. Therefore, not only the partial reflection part 620 is fixed to the notch of the first installation groove 310, but also the notch of the first installation groove 310 is closed by the partial reflection part 620, forming a closed reflection area 312 and a light mixing area 311.

[0062] In some embodiments, the lamp further includes: a substrate 540 .

[0063] The first light emitting component 510 is disposed on the substrate 540 .

[0064] Specifically, the substrate 540 is spaced from the chassis 100 so that there is more heat dissipation space around the substrate 540, thereby improving the substrate 540, the first lighting assembly 510, and other electrical components disposed on the substrate 540. In addition, the substrate 540 abuts against the bottom end of the inner wall 211 and the bottom end of the outer wall 221 to enclose the first installation groove 310 together with the inner wall 211 and the outer wall 221.

[0065] In some embodiments, the annular diffuser 400 is located on the substrate 510, the diffuser support plate 420 is spaced from the substrate (540), and the substrate 510 is also provided with a control chip located below the diffuser support plate 420. Thus, not only is the space utilization efficiency high, which is conducive to the miniaturization of the lamp, but also, on the one hand, the placement or fixation of the annular diffuser 400 is achieved, and on the other hand, more heat dissipation space is further provided around the substrate 540, which improves the substrate 540, the first lighting assembly 510, the control chip and other electrical components arranged on the substrate 540.

[0066] In some embodiments, the outer frame 220 further includes an outer frame connecting portion 223 and an outer peripheral wall 224 .

[0067] Correspondingly, the lamp further includes: an annular wire mask 710 and a second light-emitting component 520 .

[0068] The outer frame connection portion 223 extends from the bottom end of the outer side wall 221 toward a direction away from the first installation groove 310 , and the outer peripheral wall 224 surrounds the outer side wall 221 and is connected to the outer frame connection portion 223 .

[0069] Specifically, the outer peripheral wall 224, the outer side wall 221 and the outer frame connecting portion 223 together enclose a second mounting groove 320, and the second mounting groove 320 and the first mounting groove 310 are respectively located on both sides of the outer side wall 221, and the groove width of the second mounting groove 320 is smaller than the groove width of the first mounting groove 310, so as to achieve a linear lighting effect different from the deep thousand-layer light effect through the second light-emitting component 520.

[0070] At the same time, the annular wire mask 710 is clamped in the notch of the second installation groove 320, and the two side edges of the annular wire mask 710 are respectively connected with a first elastic flange 711 and a second elastic flange 712 extending toward the bottom of the second installation groove 320. The first elastic flange 711 abuts against the outer side wall 221, and the second elastic flange 712 abuts against the outer peripheral wall 224.

[0071] Correspondingly, the second light emitting component 520 is disposed in the second mounting groove 320 , and the light emitted by the second light emitting component 520 is emitted through the annular line mask 710 .

[0072] Therefore, on the basis of forming the mixed light area 311 by the outer wall 221, not only can the first elastic flange 711 abut against the outer wall 221, and the second elastic flange 712 abut against the outer peripheral wall 224, so as to realize the annular line mask 710 being fixedly connected to the notch of the second mounting groove 320 to form a closed line light illumination cavity, but also, by utilizing the inwardly inclined outer wall 221, the gap at the abutting position of the first elastic flange 711 will be hidden behind the annular line mask 710, thereby not only facilitating the realization of a narrow frame matching structure with a simple structure, but also the matching structure can be seamlessly matched, which is conducive to realizing a line light illumination effect without light leakage.

[0073] In some embodiments, the second light-emitting component 520 is fixed to the outer frame connection portion 223, and the outer peripheral wall 224 forms an inclined clamping surface 2251 on one side facing the outer side wall 221, the inclination direction of the clamping surface 2251 is opposite to the inclination direction of the outer side wall 221, and the second elastic flange 712 abuts against the clamping surface 2251. Therefore, the abutting position of the second elastic flange 712 will also be hidden behind the annular wire mask 710, so as to facilitate the realization of a matching structure with a narrower frame and better light leakage improvement effect.

[0074] Furthermore, a protruding clamping portion 225 is formed on one side of the peripheral wall 224 facing the outer side wall 221 , and a bottom end of the clamping portion 225 is higher than the second light-emitting component 520 .

[0075] Correspondingly, the clamping surface 2251 is located on the clamping portion 225, and the bottom end of the second elastic flange 712 has a wire mask hook 713 protruding toward the clamping portion 225, so that when the second elastic flange 712 abuts against the clamping surface 2251, the wire mask hook 713 is hooked to the bottom end of the second elastic flange 712, thereby increasing the connection firmness between the annular wire mask 710 and the outer frame 220.

[0076] In some embodiments, the bottom end of the outer wall 224 is lower than the bottom end of the outer wall 221, and an inner connecting portion 213 is formed on the side of the inner wall 211 facing away from the first mounting groove 310, the bottom end of the inner connecting portion 213 is lower than the bottom end of the inner wall 211, and the bottom end of the outer wall 224 and the bottom end of the inner wall 211 both abut against the chassis 100, so that there is a gap between the first light-emitting component 510 and the chassis 100.

[0077] Furthermore, the inner connecting portion 213 is a step-like structure, and a slot is formed on the surface of the step-like structure. Accordingly, when the elastic flange 721 of the main mask abuts against the side of the inner wall 211 toward the main lighting area 110, the bottom end of the elastic flange 721 of the main mask is inserted into the slot to further limit the main mask 720.

[0078] In other embodiments, the second light emitting assembly 520 may also be fixed to the inner side of the outer peripheral wall 224 , so that the annular wire mask 710 may be correspondingly narrower, to further achieve a more optimized narrow frame.

[0079] In some embodiments, the total reflection portion 610 is a total reflection sheet, and the partial reflection portion 620 is a semi-reflection sheet.

[0080] In some embodiments, the lamp further includes: a power drive module 810 and a hanging plate 820 disposed on the installation side 101, wherein the hanging plate 820 is used to fix the lamp to the installation base.

[0081] Although the present invention is disclosed as above, the present invention is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the scope defined by the claims.
