We diviided the led light according to the using eviiroment. Most of our product is the commercial LED Lighting
Commercial lighting is a term used to describe lighting that is used in commercial spaces, including auto dealerships, distribution centers, churches, factories, offices, and warehouses. Unlike residential lighting, commercial lighting is made to withstand more abuse and has a longer lifespan.
While the focus of residential lighting is often on aesthetics, commercial lighting is task orientated. Commercial lighting systems are designed based on what the application is. For example, in an office-type setting, you may see task lighting, which illuminates specific areas where employees need concentrated light to be able to perform their jobs.

2. Automatic Door Closing Function After the occupant and the visitor come in to talk to each other, when the resident allows the visitor to enter, the * key on the extension can be used as the unit's security door. * After the visitor enters the unit security door, the unit security door is pulled under the door closer. Automatically closes the door.
3. Anti-theft function unit The security door is normally closed, and the non-unit personnel cannot enter the unit corridor, thus effectively preventing some miscellaneous personnel from entering the unit corridor, and effectively preventing thieves from entering the corridor. This adds a safety guarantee for the community residents. .
4. Keys, swipe cards* function When the occupants return home, they can use the key*, the host's built-in ID access controller, and the resident can use the proximity card to swipe the card*
Technical features and advantages
1. Modularity Modular design is used in circuit design. The communication circuit of each device adopts the same structure, which ensures the consistency and compatibility of the signal, and plays a signal-enhancing role. The damage of a single household will not affect the use of other households, and the installation and debugging are convenient.
2. Equipment compatibility All levels of equipment use the same product, automatically identify the installation level, set the equipment parameters, and have a high degree of intelligence. No manual intervention is required. Solved the incompatibility of each layer in the system in the past.
3. Stability The system uses a single power supply, audio and ground separation, indoor extension and the door of the host audio through optical isolation, to ensure that the audio does not interfere with each other. The audio is amplified and output to a large extent, the amplitude of the audio transmitted on the line is high, and the input audio is adjusted only slightly, which improves the signal to noise ratio of the audio transmission. Bus isolation at all levels.
4. Reliability System communications are transmitted using a self-developed serial communication protocol. The protocol is divided into physical layer, transport layer, and target layer. The physical layer signal output circuit adopts a push-pull structure and has a strong signal output capability. After a command is issued, it waits for a response. The sending command receives a response and sends it successfully. Otherwise, it counts as a transmission failure, retransmits it at the target layer, and sends it in normal use. One success.
5. Power off automatically starts the backup power supply for each unit of the entire system. In the event of a power failure, the backup power supply can be automatically activated within 1 second.
6. System power supply over-voltage, under-voltage protection All power supply has over-voltage and under-voltage protection. The protected backup battery can prolong service life.
7. The system circuit short-circuit does not affect the entire system system. The layered module can be isolated and protected. Once the circuit is short-circuited, it will not affect the use of other households and the entire system.
