Description

Technical Field

[0001] This utility model relates to the field of panel light technology, and in particular to a multifunctional intelligent anti-glare panel light. Background Technology

[0002] In modern office settings, indoor lighting systems are a core infrastructure, and their rationality directly impacts the comfort of office workers and energy efficiency. Currently, office workers spend long hours sitting in brightly lit indoor environments, continuously exposed to a fixed brightness of light. Over time, this can easily lead to visual fatigue, dizziness, and negatively affect work efficiency and health. Furthermore, most existing indoor lighting fixtures use a fixed-power lighting mode, failing to consider the significant differences in outdoor light intensity at different times of day (morning, noon, and evening), while maintaining a single brightness output. This results in indoor lighting fixtures operating at high brightness even during the day when outdoor light is abundant, causing unnecessary energy consumption and failing to meet the actual needs of energy conservation and emission reduction.

[0003] Meanwhile, some lighting fixtures have inadequate optical design, resulting in direct light and glare when viewed directly or from specific angles. This glaring light directly stimulates the eyes, reducing visual comfort and potentially impacting eye health. Utility Model Content

[0004] To address the aforementioned issues, this invention provides a multifunctional intelligent anti-glare panel light that improves visual comfort, energy efficiency, and lighting rationality.

[0005] Therefore, the technical solution of this utility model is: a multifunctional intelligent anti-glare panel light, including a back panel, several LED light groups and a panel, wherein the panel is provided with multiple concave reflectors arranged in a matrix, and the bottom of the reflectors is provided with an opening to accommodate the LED light groups; the panel is also provided with a human body sensor and a light sensor, wherein the human body sensor is used to sense the status of people in the office area, and the light sensor is used to detect the ambient light level; it also includes a control module and a drive module, wherein the control module receives signals from the human body sensor and the light sensor, and controls the brightness of the LED light groups through the drive module.

[0006] Based on the above scheme and as a preferred embodiment of the above scheme: the LED light group includes LED beads and a lens, and the lens is provided with an anti-glare film.

[0007] Based on the above scheme and as a preferred embodiment of the above scheme: the light sensor converts the light signal into an electrical signal and transmits it to the control module. The control module receives the ambient light signal from the light sensor and outputs the corresponding PWM control signal.

[0008] Based on the above scheme and as a preferred embodiment of the above scheme: the drive module receives the PWM signal from the control module and adjusts the current output to the LED group according to the signal duty cycle.

[0009] Based on the above solution and as a preferred solution: when the human body sensor detects that no one is in the office area, the control module controls the LED light group to maintain low power brightness; when the human body sensor detects that a person has entered, the control module controls the LED light group to switch to high power lighting.

[0010] Compared with the prior art, the beneficial effects of this utility model are: 1. Replacing the large light-emitting surface of traditional panel lights with a small concave light-emitting surface can reduce the luminous intensity per unit area, and the concave design can block some glare effects; installing a frosted anti-glare film on the outside of the lens of the LED component can effectively reduce its glare value and also reduce direct light.

[0011] 2. A human body sensor is installed on the front of the panel, which can maintain low power brightness when no one is present and increase the lighting power when someone arrives. At the same time, a light sensor is also installed on the front of the panel, which is matched with the driver power supply program. It can automatically adjust the output brightness of the lamp according to the current ambient light level, so as to maintain a stable brightness in the entire office environment, thereby reducing unnecessary energy consumption and meeting the needs of energy conservation and consumption reduction.

The microcontroller U1 calculates the required brightness adjustment based on the collected ambient light signal and then outputs the corresponding PWM control signal. The PWM signal output by the microcontroller U1 is transmitted to the DIPLED buck constant current driver chip U8 in the constant current and current regulation circuit. Chip U8 adjusts the current output to the light source according to the duty cycle of the PWM signal, ultimately achieving automatic adjustment of the lamp's output brightness to maintain a stable ambient light level.
