[0110] The optical dimming component 4 in this embodiment can refer to the light distribution control technology in the prior art, but it is also different from the prior art; for example... Figure 3 The optical dimming component 4 includes: a first substrate 401, a liquid crystal layer 402, at least two sets of transparent electrodes 403, a second substrate 404, and at least one electrode driving circuit 405; wherein, one side of the liquid crystal layer 402 is disposed on one side of the first substrate 401; the transparent electrodes 403 are evenly distributed at both edges of the liquid crystal layer 402; the second substrate 404 is disposed on the other side of the liquid crystal layer 402; the electrode driving circuit 405 is electrically connected to the transparent electrode layer 403 and is used to provide a driving voltage to the transparent electrodes 403; the electrode driving circuit 405 is electrically connected to the control component 2 and is used to drive the corresponding transparent electrodes 403 to generate voltage according to the light spot adjustment command, thereby patterning the liquid crystal layer 402.

[0111] Preferably, in this embodiment, due to the use of a circular shape LED Therefore, the transparent electrode 403 is designed with four arc segments, which together form a complete circle; a gap of approximately 5 mm is provided between any two adjacent rings. mm Alternatively, you can set it yourself according to the actual situation.

[0112] like Figure 4The transparent electrode 403 includes a first transparent electrode 4031, a second transparent electrode 4032, a third transparent electrode 4033 and a fourth transparent electrode 4034; the first transparent electrode 4031 and the second transparent electrode 4032 are symmetrically arranged at the edge position of the liquid crystal layer 402; the third transparent electrode 4033 and the fourth transparent electrode 4034 are symmetrically arranged at the edge position of the liquid crystal layer 402; the first transparent electrode 4031 and the second transparent electrode 4032 form a first light spot adjusting area; the third transparent electrode 4033 and the fourth transparent electrode 4034 form a second light spot adjusting area; the first transparent electrode 4031, the second transparent electrode 4032, the third transparent electrode 4033 and the fourth transparent electrode 4034 are electrically connected with the electrode driving circuit 405, and the transparent electrodes on the same side have the same electrical property, which is used to drive any two of the first transparent electrode 4031, the second transparent electrode 4032, the third transparent electrode 4033 and the fourth transparent electrode 4034 according to the light spot adjusting instruction to control the liquid crystal layer 402 in a region; or, the first transparent electrode 4031, the second transparent electrode 4032, the third transparent electrode 4033 and the fourth transparent electrode 4034 are simultaneously driven to control the liquid crystal layer 402 as a whole; and the light spot patterns of the two regions do not coincide.

[0113] In use, if the light spot adjusting instruction issued by the user is a pattern, such as a circle or an ellipse, at this time, the first transparent electrode 4031 and the third transparent electrode 4033 on the same side have the same polarity, such as positive; the third transparent electrode 4033 and the fourth transparent electrode 4034 have the same polarity, such as negative; after the electrode driving circuit 405 supplies power to the first transparent electrode 4031, the second transparent electrode 4032, the third transparent electrode 4033 and the fourth transparent electrode 4034, a complete control area is formed, which is convenient for forming a pattern, such as a circle or an ellipse; when the user wants to issue different light spots in the same LED circle area, such as displaying different light spots in the upper and lower parts respectively; at this time, the electrode driving circuit 405 provides different polarities to the first transparent electrode 4031 and the second transparent electrode 4032 to form a first light spot adjusting area; the electrode driving circuit 405 provides different polarities to the third transparent electrode 4033 and the fourth transparent electrode 4034 to form a second light spot adjusting area; the first light spot area and the second light spot area are regarded as separate control areas, and different light spot adjusting instructions are used to dynamically control the respective areas to form the expected pattern.

[0114] In order to realize LED the power consumption of the lamp, the light emitting units not in the light spot range are made to work as much as possible, in the embodiment, please refer to Figure 2The light source assembly 3 comprises a support plate 301, at least two light emitting units 302, a light source driving circuit 303, a light cup plate 304, a protection plate 305, and a cover plate 306. LED The light emitting units 302 are uniformly distributed on the support plate 301.

[0115] In the embodiment, as an example of a circular light spot, Figure 5 the dashed part in the light spot is the shape of the light spot; and the light spot pattern is compared with the support plate 301 with the center of the dashed line as the reference; the light emitting units outside the periphery of the dashed line will be shielded and not work. Figure 5 Due to the shielding of some light emitting units, in order to ensure the brightness, the current of the working light emitting unit 302 during work can be adjusted to make the brightness of the working light emitting unit larger to meet the brightness requirement.

[0116] The existing LED lamp, the heat dissipation system is all through the heat dissipation fins behind the shell 101 to dissipate heat, which belongs to passive heat dissipation. In the embodiment, due to the shielding of some light emitting units, the positions of the working light emitting units are relatively concentrated, and the heat generation positions are also relatively concentrated. In order to dissipate heat more targetedly, the embodiment provides an active heat dissipation mode, which is as follows.

[0117] As shown in Figure 2 , the heat dissipation assembly 1 comprises a shell 101 and a movable mechanism 102. B The movable mechanism 102 is arranged inside the shell 101. AThe control component 2 is electrically connected to the active mechanism 102 and is used to dynamically control the heat dissipation of the corresponding position of the housing 101 according to the light spot adjustment command, thereby enhancing the local heat dissipation of the light-emitting unit in the working state in the light source component 3.

[0118] Preferred, such as Figure 6 The through hole 101 on the housing 101 A Along the heat dissipation fins 101 B The same grooves are symmetrically arranged; the movable mechanism 102 is disposed inside the housing 101 and located in the through hole 101. A On one side, two through holes 101 symmetrically arranged in the same groove are dynamically adjusted by the control component 2 according to the light spot adjustment command. A The closed state forms a reinforced cooling structure for the light-emitting unit area that is in operation.

[0119] Specifically, such as Figure 7 The movable mechanism 102 includes: a connecting frame 1021, a driving unit 1022, a movable component 1023, and a temperature acquisition unit 1024. The connecting frame 1021 is screwed inside the housing 101. The driving unit 1022 is screwed onto the connecting frame 1021, with its output end facing the housing 101. The movable component 1023 is located at the output end of the driving unit 1022 and swings in response to the rotation of the driving unit 1022. The driving unit 1022 is electrically connected to the control component 2 and dynamically adjusts the pre-rotation angle of the driving unit 1022 according to the light spot adjustment command, thereby forming a reinforced cooling structure for the light-emitting unit area in operation. Preferably, the area of ​​the end of the movable component 1023 is larger than that of the through hole 101. A The area. A temperature acquisition unit 1024 is disposed inside the housing 101 and is used to acquire temperature data within the housing 101; the temperature acquisition unit 1024 is electrically connected to the control component 2 and is used to adjust the pre-rotation angle of the drive unit 1022 according to the temperature data. For example... Figure 8 The connecting bracket 1021 opens or closes the through hole 101 without interfering with the moving part 1023. A Ideally; through hole 101 A A tapered orifice design is preferable to accelerate airflow. Figure 6 and Figure 8 The arrows in the text all indicate the swing direction of the moving part 1023.

[0120] In use, the position of the main heat source, i.e., the position where the light-emitting units are concentrated, is obtained according to the light spot adjustment command. The driving unit 1022 drives the movable part 1023 to swing, thereby adjusting the through hole 101. AFrom the closed state to the open state. The through hole 101 A In the closed state, consistent with the prior art, passive heat dissipation is performed through the heat dissipation fins behind the shell 101. As shown in Figure 9 When the two through holes 101 A symmetrically arranged in the same groove are opened, the heat accumulation area will move from the through hole 101 A close to the other through hole 101 A . When the gas is discharged, the heat dissipation fins act as high obstacles, forming a canyon effect, quickly carrying hot gas away from the gas discharge through hole 101 Figure 9 , forming a negative pressure, increasing the flow rate of the hot gas discharge through hole, and reducing the air pressure in the shell 101; at the same time, the other through hole in the same groove forms a cold gas inlet due to the reduced air pressure in the shell 101, and the cycle is repeated to quickly reduce the temperature of the heat source area and thus the temperature in the shell 101.

[0121] When the outside is in a rainy day or winter, the temperature is relatively low, and the heat dissipation of the shell 101 is good, so at this time, the temperature in the shell 101 is periodically acquired by the temperature acquisition unit 1024, and if the threshold is not reached, the opening angle of the through hole 101 A can be adjusted later to prevent water from entering or electromagnetic interference.
