Microwave sensor, also known as microwave radar, is an instrument made using the Doppler principle of electromagnetic waves. Microwave sensing is known by changes in reflected waves when an animal is approaching or away. Induction lights are often used in corridors, corridors, garages and other scenes, and microwave sensors can also be used as anti-theft alarm devices.                    Parking application case 1. Assume that lights A and Z are microwave lights (that is, equipped with microwave sensors), as shown below： 2. When car 1 or 2 enters the parking lot, the microwave sensor receives the microwave trigger model and reports it to the cloud. The cloud synchronously enables all microwave policies in the multicast packet, and all the lights in the multicast packet turn on, and the brightness is determined by the timed microwave policy, as shown in the figure below： 3. When the holding time of the microwave strategy is over, no other motion will trigger, and the whole set of lights will enter the standby brightness, as shown in the figure below： 4. If there are more cars in the warehouse, the strategy will be executed again, and all the lights in the group will be on again, as shown in the figure below： Note: Microwave induction is the induction of moving objects, so it is not limited to cars but also includes people walking around Microwave linkage effect Assuming that there are 6 and 5 non-microwave lamps in the lighting system, the microwave linkage function is to realize that when the microwave is triggered (that is, when the mobile trigger signal is received), the other 5 non-microwave lamps are driven to simulate the microwave and execute the microwave policy, provided that the 6 lamps need to set the same microwave policy within the same microwave policy effective time.Suppose there are 6 lamps in the lighting system, 1 microwave lamp and 5 non-microwave lamps.                               The microwave linkage function is to realize that when the microwave lamp is triggered (that is, when the mobile trigger signal is received), the other 5 non-microwave lamps are driven to simulate the microwave and execute the microwave strategy.                                                            The premise is that all 6 lamps need to set the same microwave policy within the same microwave policy effective time The microwave linkage operation steps of the lighting control system are as follows Step 1: Set different microwave policies for the 6 lights Step 2: Group 5 non-microwave lights into the same multicast group Step 3: Turn on the “Microwave report switch” of the microwave lamp and select “Microwave Association Group Number”. After the setting is complete, whenever the microwave lamp receives the trigger signal, the non-microwave lamp will also be linked to light up according to the microwave strategy, so as to achieve the effect of one microwave lamp driving multiple non-microwave lamps Light perception: Light-controlled induction, induction is the environmental illuminance, when the environmental illuminance is lower than the limit value it will induction open, when the environmental illuminance is higher than the limit value it is closed. Light induction is generally used for induction when the light is dark, and induction is not required when the light is bright; Dual light sensing technology can automatically identify environmental natural light, distinguish natural light and artificial light Example light sensing scene: Suppose that the sense of time is set in the lighting system, the limit value of ambient brightness =100lux, hold =7H=25200S, hold brightness =100%, standby brightness =20%  

Feel the charm of Longreen’s light and shadow design Huangmugang Hub is the first “tunnel – station – bridge” integrated building in China, with a unique V-shaped giant column structure and efficient transfer of three lines (Line 7, 14, 24), which jointly form the landmark characteristics of Huangmugang Hub. The shading louver of the skylight is designed as a “master of light control”, and the louver grille adopts a special Angle and shape to adjust the day and night light and relieve The overall decoration style of the hub is unified, and the selection of materials highlights the natural texture while showing the integrated design language of architecture and interior space. The space node area combines the molding column and ceiling, and interprets the space concept of “sunlight pouring down from the gap of leaves” with the lighting atmosphere. Temperature and pressure in the space to achieve energy saving and emission reduction.

As an “urban artery”, the subway has become an indispensable means of transportation in modern cities. As an “urban artery”, the subway has become an indispensable means of transportation in modern cities. Nowadays, the subway is not only a means of transportation, but also reflects the culture and spirit of a city, and is a symbol of the soft power of the city. As an “urban artery”, the subway has become an indispensable means of transportation in modern cities.

Shenzhen Metro Line 14 lighting design On October 28, 2022, Shenzhen Metro Line 14 was officially opened. As the first eastern line in the Shenzhen Metro Express network, Line 14 starts from Xiabai Junction in Futian District, passes Futian District, Luohu District and Longgang District, and ends at Shatin Station in Pingshan District, with a total length of 50.32km and 18 stations. The opening of Line 14 will effectively promote the improvement of traffic quality in the eastern part of Shenzhen. Gangxia North Comprehensive Transportation Hub is the largest single rail transit project in China, and also the first hub of Shenzhen Metro Express network. With the theme of “Shenzhen Eye”, it aims to create a rail transit hub station that not only reflects the humanistic care of Shenzhen, but also bears the characteristics of “convergence, inclusiveness and internationalization” of Shenzhen. After completion, passenger flow transfer between rail transit lines 2, 10, 11 and 14 will be realized.   Taking the core patio of the building as the cornerstone, the design team respects the language characteristics of the architectural space, extracts the streamline form of “sunlight divergence”, adopts the mathematical principle of “Fermat spiral”, enforces the visual tension of the space, and presents a simple and atmospheric spatial effect. Through the parametric adjustment of Fermat helix curvature, the design team designed the ceiling modeling scale of each space reasonably. In order to enhance the passenger experience and create a more open and humane space, the design team introduced warm colored materials in areas such as handrails, walls and floors to create a warm urban public space. The sun pours down from the skylight, and the originally dull and depressing underground space is as transparent and bright as the outdoor space. The atmosphere of warm, bright and comfortable space is created vividly.
