Description

Technical Field

[0001] This utility model relates to the field of indoor lighting technology, specifically to an indoor zoned brightness adjustable ceiling light. Background Technology

[0002] Ceiling lights, as a common indoor lighting fixture, are favored for their unique installation method. They are directly fixed to the ceiling, taking up no extra space and being both aesthetically pleasing and practical. Ceiling lights come in a variety of designs, from minimalist modern styles to ornate retro designs, catering to different home décor needs. Their even light distribution effectively illuminates the entire room, enhancing living comfort. Furthermore, ceiling lights are often equipped with energy-saving bulbs or LED light sources, making them both environmentally friendly and economical, ideal for modern homes and offices.

[0003] Traditional adjustable ceiling lights often regulate brightness by manually or automatically adjusting the input power. This global dimming method can lead to overexposure in the near-window area and insufficient illuminance in the core area, resulting in uneven lighting throughout the space and wasted energy. Furthermore, existing smart adjustable lights regulate brightness by sensing the brightness of natural light through built-in photosensors. However, single sensors inside the lamp body often receive too little light, leading to inaccurate control. Using high-sensitivity sensors would be more susceptible to diffuse reflection. Therefore, we propose an indoor zoned brightness adjustable ceiling light. Utility Model Content

[0004] To address the above problems, this utility model provides an indoor zoned brightness adjustable ceiling light, which overcomes the shortcomings of the prior art, has a reasonable design, and a compact structure.

[0005] To achieve the above objectives, this utility model provides the following technical solution: An indoor zone-dimmable ceiling light includes a housing and an inner housing installed inside the outer housing. A component platform is installed inside the inner housing. A power driver, a photosensitive sensor, a control module, and a snap-fit ​​tube for vertical connection are installed on the upper part of the component platform. A light-emitting component is installed on the lower part of the component platform, and a lampshade is installed on the lower part of the light-emitting component. The component platform is an "h"-shaped sheet metal fastener. A part of the component platform can form a cavity with the inner shell. A control module is installed inside the cavity. Another part of the component platform forms an open part with the inner shell. A power driver and a photosensitive sensor are installed in the open part. Clip tubes are also symmetrically installed in the open part. The clip tubes are equipped with hangers that cooperate with them.

[0006] Preferably, the light-emitting component comprises at least three LED light groups, namely three independent LED arrays for the near window area, the transition area, and the core area. When there is sunlight, the near window area is adjusted to be the secondary bright area, the intermediate transition area to be the bright area, and the core area far from the window to be the strong bright area.

[0007] Preferably, the snap-fit ​​tube has several limiting holes, and a limiting snap is installed inside the snap-fit ​​tube. The limiting snap can be adjusted up and down to snap into the limiting hole.

[0008] Preferably, the top wall of the chamber has honeycomb heat dissipation holes and a cover hole, and the cover hole is fitted with an openable flip cover.

[0009] Preferably, the inner wall of the inner shell is provided with a reflective mirror surface, which can reflect natural light to increase the amount of light received by the photosensitive sensor.

[0010] Preferably, the light-emitting component is connected to a ribbon cable at its end, and a ribbon cable hole is provided at the bottom of the chamber, through which the ribbon cable is connected to the control module.

[0011] Preferably, the open portion of the component platform is provided with a power conduit, and a power cable is built into the power conduit. Preferably, the hanger is made of a deformable material, and two bendable vertical hooks can be easily inserted into the clip tube below.

Detailed Implementation

[0019] The following is in conjunction with the appendix Figure 1 - Figure 6 The present invention will be further illustrated by the embodiments: In this embodiment, as Figure 1 - Figure 5As shown, an indoor zoned brightness adjustable ceiling light includes a housing 100 and an inner housing 104 installed inside the housing 100. A component platform 103 is installed inside the inner housing 104. A power driver 1031, a photosensor 1032, a control module 1035, and a snap-fit ​​tube 1034 for vertical connection are installed on the upper part of the component platform 103. A light-emitting component 107 is installed on the lower part of the component platform 103, and a lampshade 105 is installed on the lower part of the light-emitting component 107.

[0020] The component platform 103 is an "h"-shaped sheet metal fastener. A portion of the component platform 103 can form a cavity with the inner shell 104. The top wall of the cavity has honeycomb heat dissipation holes 1037 and a cover hole. The cover hole is fitted with an openable flip cover 102. The control module 1035 is installed inside the cavity. When the power is relatively high, the internal temperature is too high, which will cause the components to overheat and reduce their service life. The honeycomb heat dissipation holes 1037 help dissipate heat inside the lampshade. When maintenance is required, the internal parts can be inspected by opening the flip cover 102. Another portion of the component platform 103 forms an open part with the inner shell 104. The open part is fitted with a power driver 1031 and a photosensitive sensor 1032. The open part is also symmetrically fitted with snap-fit ​​tubes 1034. The snap-fit ​​tubes 1034 are equipped with matching hangers 101. The hangers 101 are made of deformable material and can be bent. Two vertical hooks can be easily inserted into the snap-fit ​​tubes 1034 below. The hangers 101 are fixedly installed on the ceiling through two screw holes.

[0021] The snap-fit ​​tube 1034 has several limiting holes, and a limiting snap-fit ​​1033 is installed inside the snap-fit ​​1034. The limiting snap-fit ​​1033 can be adjusted up and down to snap into the limiting hole, thereby cooperating with the hanger 101 to adjust the overall height of the lamp. By adjusting the overall height, the amount of light entering the photosensitive sensor 1032 can also be changed to adapt to the sunlight intensity of different scenes.

[0022] The inner wall of the inner shell 104 is provided with a reflective mirror, which can reflect natural light to increase the amount of light received by the photosensitive sensor, thereby accurately adjusting the brightness.

[0023] The light-emitting component 107 consists of at least three LED light groups, namely three independent LED arrays for the near window area, the transition area, and the core area. When there is sunlight, the near window area is adjusted to be the secondary bright area, the middle transition area to be the bright area, and the core area away from the window to be the strong bright area. The light-emitting component 107 is connected to the control module 1035 through the ribbon cable 1071 passing through the ribbon cable hole 1036. After the photosensitive sensor 1032 receives the outdoor light, it transmits the outdoor light intensity information to the control module 1035. The control module 1035 adjusts the different brightness of the near window area, the transition area, and the core area according to the signal, so that the core area is sufficiently illuminated and can supplement the brightness of the near window area, so that the overall indoor lighting is uniform.

[0024] The component platform 103 has an open section with a power line conduit 1039, and a power line 1040 is built into the power line conduit 1039. In this embodiment, as Figure 6 As shown, an LED light strip is installed at the bottom of the housing 100. The LED light strip also consists of several independent LED light groups and is connected to the control module 1035 to adjust the brightness synchronously with the light-emitting component 107. The control module 1035 includes an environmental sensing unit, a logic processing unit, a clock management unit, an RTC clock, and a dimming program: the built-in RTC chip presets a weekday / holiday mode and starts a linear dimming (reducing by 8% per minute) one hour before the end of the workday to avoid visual discomfort caused by sudden shutdown.

[0025] Control circuit logic such as Figure 7 - Figure 11 As shown, the schematic diagram of the minimum microcontroller system is responsible for running the program, debugging and downloading the program, realizing the microcontroller's reset function, and configuring the startup mode through the system clock signal. Its control part is as follows: First, an STM32F103C8T6 chip minimum microcontroller system is built. The control program is uploaded to the microcontroller through the download circuit. Using signals provided by a photosensitive sensor, the microcontroller performs zoned dimming control based on a pre-set threshold program. This invention mainly uses two control methods: button control and photosensitive control. If the current light environment conditions meet the photosensitive sensor's threshold conditions, the microcontroller outputs signals from different GPIO ports according to the pre-set program to precisely control the lights in each zone. If the current light environment conditions do not meet the photosensitive sensor's threshold conditions, button control can still be used to adjust the lighting to supplement the current light environment.

[0026] The technical features of the embodiments described above can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combination of these technical features does not contradict each other, it should be considered to be within the scope of this specification.
