Abstract
Description
Technical Field
[0001] This utility model relates to the field of lighting device technology, and in particular to an intelligent sensor elevator lighting device. Background Technology
[0002] Elevator lighting is a core subsystem within an elevator system, specifically responsible for lighting both inside and outside the elevator car. Its design must balance functionality, safety, and user experience. Existing elevator lighting systems typically consist of a main light source module, an intelligent control system, and an emergency lighting unit to meet both normal and emergency lighting needs inside the elevator. The mainstream solution for the main light source module currently uses 2835 / 5050 SMD LEDs, offering an adjustable color temperature range of 2700K-6500K and providing 8-12W / m². 2 The power density is adjusted to meet the illumination requirements inside the elevator car. Its optical structure typically includes a light guide plate, a diffusion film, and a reflective film to ensure the main light source module's fog resistance and reflectivity. The intelligent control system is implemented collaboratively by an environmental sensing network, an intelligent control chip, and a control program. The environmental sensing network usually consists of an illuminance sensor, a human presence detection module, and a light source module wake-up module to monitor various environmental factors inside the car, and then coordinate with the intelligent control chip and control program to intelligently control the elevator lighting device.
[0003] However, existing elevator lighting devices have not undergone targeted heat dissipation optimization for environmental sensing networks. In particular, for light source modules such as LED arrays that generate a lot of heat, high-temperature operating environments can easily have an adverse effect on the detection performance of sensors, thereby affecting the intelligent control accuracy and response efficiency of the lighting device.

Based on the specific configuration of the sensor assembly 40, the intelligent sensing elevator lighting device 1 of this utility model can intelligently control the elevator according to the entry and exit of personnel, light intensity, gas environment, and elevator lifting and lowering status. When personnel enter the elevator, the gas environment inside the elevator is normal, and the lifting and lowering status is normal, the light-emitting module 20 is turned on and operates normally; otherwise, the light-emitting module 20 is turned off to enter an energy-saving state, thereby greatly improving the energy-saving capability and safety of elevator operation.
[0036] In one embodiment, the millimeter-wave radar array includes a plurality of millimeter-wave radars 41, which are equidistantly arranged on the bottom wall surface of the corresponding third mounting part 13 along a preset direction to form a millimeter-wave radar array.

The first receiving cavity 111 is disposed on the top of the housing 10, and the first mounting plate 112 is fastened to the top side of the first receiving cavity 111, thereby making the first mounting portion 11 form a relatively closed mounting cavity. Specifically, the control module is housed in the first receiving cavity 111, and the control module is connected to the first mounting plate 112.
[0039] Furthermore, the second mounting portion 12 includes a second receiving cavity 121 and a second mounting plate 122.

Specifically, the sensor assembly 40 is disposed in the corresponding third receiving cavity 131 and connected to the corresponding third mounting plate 132.
[0041] Furthermore, in one embodiment, based on the sidewalls of the first receiving cavity 111 and the second receiving cavity 121, the other sidewall of the third receiving cavity 131 is configured as an L-shaped folded plate, thereby forming a triangular prism receiving space.

Based on this, the L-shaped folded plate has a certain elastic buffer space relative to the sidewall of the second receiving cavity 121 to which it is connected, thereby improving the vibration resistance of the third receiving cavity 131, reducing the damage caused by elevator vibration to the sensor assembly 40 installed on the third mounting plate 132, and ensuring detection accuracy.

[0043] Furthermore, the second mounting plate 122 is provided with a plurality of second heat dissipation fins 1221, which are arranged in parallel on one side surface of the second mounting plate 122 facing the first receiving cavity 111. Each second heat dissipation fin 1221 extends along the length of the second mounting plate 122, thereby improving the heat dissipation performance of the second mounting plate 122 and thus conducting heat dissipation in a timely manner for the control module and the light-emitting module 20 during operation.
[0044] Furthermore, the second mounting section 12 also includes a lighting panel 123, which is disposed on the bottom side of the second receiving cavity 121 to enclose the second receiving cavity 121 and thus effectively protect the light-emitting module 20.

[0045] Furthermore, the housing 10 also includes two baffles 14, which are disposed at both ends of the housing 10 along the length direction of the housing 10 to enclose the first mounting portion 11, the second mounting portion 12, and the third mounting portion 13. In one embodiment, each baffle 14 is provided with a plurality of ventilation holes a corresponding to the two third mounting portions 13, and each ventilation hole a connects the inner and outer sides of the third mounting portion 13, thereby forming an air duct inside the third mounting portion 13 to promote heat dissipation of the sensor assembly 40.
[0046] In summary, the intelligent sensor-controlled elevator lighting device disclosed in this invention monitors the environmental information inside the elevator using sensor components. The control unit can intelligently control the light-emitting module, including controlling the opening and closing of the light-emitting unit and adjusting its brightness.
