[0002] In the prior art, there are three commonly used methods for lamps to produce a linear narrow beam spot on the illuminated surface and control the position and length of the linear narrow beam spot: 1.

[0027] In actual application, a dimming bracket 4 is arranged on the mounting plate 1 so that the focusing lens 2 and the thin film optical lens 5 can be reasonably assembled above the light emitting unit 3. The light of the light emitting unit 3 is focused by the focusing lens 2 to avoid light scattering, and the dimming bracket 4 is used to divide the light so that the light is divided into narrow light beams of different lengths, thereby reducing the light blocking area and improving the light effect. There is no need to configure a special lens, which greatly reduces the manufacturing cost of the lamp.

[0028] For example, the film optical lens 5 is a graphene film lens, which can achieve a zoom function within the visible band by lateral stretching. Compared with a semicircular shell lens and a cylindrical lens, the graphene film lens is thin and easy to process, and has a lower manufacturing cost.

[0029] In certain embodiments, in combination Figure 2 , Figure 3 and Figure 4 It can be understood that the dimming bracket 4 includes a connecting plate 41, a dividing frame 42 and two dimming plates 43, the two ends of the connecting plate 41 are respectively provided with a first connecting portion 411 and a second connecting portion 412, the first connecting portion 411 and the second connecting portion 412 are respectively connected to the mounting plate 1, the connecting plate 41 is provided with a first light outlet 410, the dividing frame 42 is connected to the top of the connecting plate 41, and the dividing frame 42 is at least partially located in the first light outlet 410, the dividing frame 42 is used to divide the light of the first light outlet 410, and support plates 414 are respectively provided on both sides of the first light outlet 410, the two dimming plates 43 are respectively arranged on the outer side walls of the support plate 414, the dimming plate 43 is used to divide the light on both sides of the support plate 414, and the thin film optical lens 5 is arranged on the top of the support plate 414. By connecting the connecting plate 41, the dividing frame 42 and the two dimming plates 43, the light is divided into narrow beams of different lengths, reducing the light blocking area, thereby improving the light effect. At the same time, a grid structure is formed between the connecting plate 41, the dividing frame 42 and the two dimming plates 43, which has an anti-glare effect.

[0030] In certain embodiments, such as Figure 2 and Figure 3 As shown, the bottom of the first connection part 411 and the bottom of the second connection part 412 are both provided with an extension part 413, and the extension part 413 is connected to the top of the mounting plate 1. The extension part 413 increases the contact area between the bottom of the first connection part 411 and the bottom of the second connection part 412 and the top of the mounting plate 1, so that the connection between the connection plate 41 and the mounting plate 1 is more stable, further improving the overall stability of the light control assembly.

[0031] In certain embodiments, such as Figure 2 and Figure 4As shown, the dividing frame 42 includes a dividing plate 421, the dividing plate 421 is connected to the top of the connecting plate 41, a second light outlet 4212 is provided on the dividing plate 421, and the second light outlet 4212 is located in the first light outlet 410, and dividing parts 4211 are respectively provided on both sides of the second light outlet 4212, and the dividing parts 4211 are used to divide the light of the second light outlet 4212. Through the dividing function of the dividing plate 421 and the second light outlet 4212, the dividing frame 42 can divide the light of the first light outlet 410.

[0032] In certain embodiments, such as Figure 2 As shown, bending portions 431 are respectively provided at both ends of the dimming plate 43, and the bending portions 431 are connected to the outer wall of the support plate 414. The dimming plate 43 forms a space gap between the bending portions 431 and the outer wall of the support plate 414 so that the light is irradiated from the space gap, thereby realizing that the dimming plate 43 divides the light on both sides of the support plate 414.

[0033] In certain embodiments, such as Figure 1 and Figure 2 As shown, the outer side wall of the support plate 414 is provided with a support portion 4141, and the film optical lens 5 is connected to the support portion 4141. The contact area between the film optical lens 5 and the top of the support plate 414 is increased by the support portion 4141, so that the connection between the film optical lens 5 and the support plate 414 is more tightly secured. In the actual installation process, the film optical lens 5 can be attached to the support portion 4141 by glue, which is simple to operate, simplifies the lens installation steps, and further improves the installation efficiency of the light control assembly.

[0034] In certain embodiments, such as Figure 2 As shown, the top of the mounting plate 1 is provided with an inclined portion 11, the connecting plate 41 is parallel to the top surface of the inclined portion 11, and the light emitting unit 3 is provided on the inclined portion 11.

[0035] In certain embodiments, such as Figure 1As shown, the light-emitting unit 3 includes a lamp board 31 and RGBW lamp beads 32, the RGBW lamp beads 32 are electrically connected to the lamp board 31, and the lamp board 31 is connected to the inclined portion 11. Since most of the lamps in the prior art use multiple lamp beads arranged in a linear manner, when multiple lamp beads emit lights of different colors, once a certain lamp bead in the middle is not lit, a stratification phenomenon will occur, affecting the multi-color mixing effect of the light; compared with the prior art that arranges multiple lamp beads in a linear manner, the present application uses RGBW lamp beads 32, which have four light-emitting elements arranged in a field shape, which can avoid the stratification phenomenon of lights of different colors and further improve the multi-color mixing effect of the light.

[0036] In certain embodiments, such as Figure 1 As shown, compared with the semicircular shell lens and cylindrical lens in the prior art, the condenser lens 2 of the present application is in the shape of a frustum, which is a universal shape, is convenient for the condenser lens 2 to be molded, has a simple production process and a low manufacturing cost; a light-transmitting hole 21 is provided in the middle of the condenser lens 2, and the RGBW lamp beads 32 are located in the light-transmitting hole 21, so that the light emitted by the RGBW lamp beads 32 can be completely condensed by the condenser lens 2, thereby further improving the condensing effect of the condenser lens 2; a protrusion 22 is provided at one end with a smaller diameter of the condenser lens 2, and a positioning hole 311 corresponding to the protrusion 22 is provided on the lamp board 31, and the protrusion 22 is matched and connected with the positioning hole 311; through the matching connection between the protrusion 22 and the positioning hole 311, the condenser lens 2 can be quickly and accurately spliced ​​with the lamp board 31, thereby greatly improving the assembly efficiency of the present light control component.

The two grooves 4101 on the second light outlet 4212 are connected with the ring portion 23 of the condenser lens 2, thereby further improving the convenience of installing the condenser lens 2.

[0038] The present invention also provides a lamp, such as Figure 5As shown, it includes a lamp housing 6, a control board 7, a light-transmitting plate 8 and a light-control component described in any one of the above embodiments, wherein the lamp housing 6 is provided with a receiving cavity, the control board 7 and the light-control component are arranged in the receiving cavity, and the control board 7 and the light-control component are electrically connected, and the light-transmitting plate 8 is arranged at the cavity opening of the receiving cavity, and the light control of the light-control component can be realized by the control board 7, thereby improving the convenience of light control; wherein, the control board 7 can be a single-chip microcomputer, and the light control by the single-chip microcomputer belongs to the commonly used technical means in the prior art, which will not be repeated here; the light-transmitting plate 8 is provided with a shading area and a light-emitting area, and the shading area is used to reduce light scattering, and the light-control component is located in the light-emitting area.

[0039] In summary, the present application sets a dimming bracket 4 on the mounting plate 1 so that the focusing lens 2 and the thin film optical lens 5 can be reasonably assembled above the light-emitting unit 3, and focuses the light of the light-emitting unit 3 through the focusing lens 2 to avoid light scattering, and divides the light using the dimming bracket 4 so that the light is divided into narrow beams of different lengths, thereby reducing the light blocking area, thereby improving the light effect, and no special lens is required, which greatly reduces the manufacturing cost of the lamp. At the same time, the present application uses RGBW lamp beads 32, which have four light-emitting elements arranged in a field shape, which can avoid the stratification of lights of different colors and further improve the multi-color mixing effect of the light.
