[0002] Fresh food cabinets are equipment used to store and display foods that need to be refrigerated, such as meat, fish, dairy products, cooked food, vegetables, fruits, etc. Its main function is to maintain a low temperature environment in the cabinet through a refrigeration system to slow down the growth of microorganisms and chemical reactions in food, thereby extending the shelf life of food and maintaining the freshness of food. It is widely used in the retail industry and can provide consumers with fresh, healthy and safe food.

[0003] In addition to having refrigeration and heat preservation functions, the fresh-keeping cabinet should also have a good display effect. The display surface of the fresh-keeping cabinet is usually made of transparent glass or plastic, which allows customers to clearly see the food in the cabinet and is convenient for purchase. In addition, the fresh-keeping cabinet is also equipped with lighting to provide sufficient lighting for customers to purchase goods. However, in traditional fresh-keeping cabinets, the lighting is usually in a long-on state, and there is a waste of lighting during the period when no one is shopping, resulting in a high overall energy consumption of the fresh-keeping cabinet. For this reason, the present application proposes a lighting device structure for a fresh-keeping cabinet. Utility Model Content

[0028] As a preferred technical solution in this embodiment, only one first light board 7 is provided, and at least two second light boards 8 are provided. A controller 9 for controlling the opening and closing of the first light board 7 and the second light board 8 is installed on the mounting substrate 4. The human body sensing module 3 includes a mounting seat 17 fixed to the front end surface of the top of the cold cabinet 1 and a human infrared sensor 18 installed on the mounting seat 17. The human body infrared sensor 18 is connected to the controller 9 for control. The controller 9 is used to control only one first light board 7 to be in a constantly lit state, so as to provide weak lighting for the goods in the cold cabinet 1. When there is a purchase When a shopper approaches the cold cabinet 1, the human infrared sensor 18 on the top of the cold cabinet 1 senses the approach of the human body and transmits a signal to the controller 9, which controls at least two second light panels 8 to turn on, providing sufficient light for the cold cabinet 1 to facilitate the shopper's shopping. After the shopper moves away from the cold cabinet 1, the human infrared sensor 18 can no longer sense the human body, and the controller 9 controls the second light panels 8 to turn off, thereby achieving the purpose of energy saving, reducing energy consumption and light pollution, and at the same time ensuring that sufficient lighting is provided when shopping is needed, improving user experience and enhancing the energy efficiency performance of the cold cabinet 1.

[0029] Furthermore, in the present embodiment, a side of the mounting base 17 away from the cold cabinet body 1 has a downwardly inclined mounting surface a, and the angle range between the mounting surface a and the vertical direction is 30 to 45°. By using the mounting surface a and adopting an inclined angle range of 30 to 45°, it is beneficial for the human infrared sensor 18 to sense and detect the area in front of the cold cabinet body 1.

[0030] In a further embodiment, a frame 5 is fixedly connected to the mounting substrate 4, and a light-transmitting cover 6 is embedded in the frame 5. The cross-section of the light-transmitting cover 6 is a semicircular structure, which is used to protect the first light board 7 and the second light board 8 on the mounting substrate 4. A through slot 10 is provided on the side of the frame 5 away from the mounting substrate 4, and the light-transmitting cover 6 is movably embedded in the through slot 10. A flange plate 15 is provided on the surrounding walls of the side of the light-transmitting cover 6 facing the inside of the frame 5. A fixing plate 11 is fixed on the end wall of the side of the frame 5 close to the mounting substrate 4. A spring 12 is provided between the fixing plate 11 and the flange plate 15. The spring 12 in the frame 5 elastically supports the flange plate 15 on the light-transmitting cover 6, which can provide elastic support for the light-transmitting cover 6, alleviate the collision force of shoppers on the mounting substrate 4 during the process of taking and placing goods, and improve the durability of the lighting structure 2. A sealing rubber ring 16 is bonded to the side of the flange plate 15 facing the light-transmitting cover 6 for sealing between the light-transmitting cover 6 and the frame 5. Connecting ear blocks 13 are provided at both ends of the fixing plate 11. The connecting ear blocks 13 are bolted to the frame 5. A connecting through hole 14 is also provided on the fixing plate 11. The connecting through hole 14 is used for connecting the frame 5 and the mounting substrate 4.

[0031] Working principle: When in use, the controller 9 is used to control only one first light panel 7 to be in a constant on state, providing weak lighting for the goods in the cold fresh cabinet 1. When a shopper approaches the cold fresh cabinet 1, the human infrared sensor 18 on the top of the cold fresh cabinet 1 senses the approach of the human body, and transmits a signal to the controller 9, controlling at least two second light panels 8 to turn on, providing sufficient light for the cold fresh cabinet 1 to facilitate shoppers to make purchases, and after the shopper moves away from the cold fresh cabinet 1, the human infrared sensor 18 can no longer sense the human body, and the controller 9 controls the second light panel 8 to go out again. By using this structural control method, the purpose of energy saving can be achieved, energy consumption can be reduced, and light pollution can be reduced, which can ensure that sufficient lighting is provided when shopping is needed, improve user experience and enhance the energy efficiency performance of the cold fresh cabinet 1, which has positive significance for environmental protection and economic benefits. Furthermore, the frame 5 and the light-transmitting cover 6 can provide protection for the first light board 7 and the second light board 8 on the mounting substrate 4, wherein the spring 12 in the frame 5 can provide elastic support for the light-transmitting cover 6, thereby alleviating the impact force on the mounting substrate 4 when shoppers take and place goods, thereby improving the durability of the lighting structure 2.
