Three technology detectors combine microwave detection technology, infrared detection technology, and micro-processing technology.
Built-in microprocessors can also use adaptive detection threshold processing technology. Its working principle is: The microprocessor "analyzes" various signals in the field, performs analog-to-digital conversion processing on the input signals, and automatically adjusts the detection threshold to shield various noise interference sources so that the detector can accurately recognize the signal. Human intrusion and noise signals increase the resistance to false alarms.
For the manufacturer, setting the detector's alarm discrimination threshold is a big challenge. If the threshold is set too low, the detector is prone to false alarms; if it is set too high, the detector cannot respond enough to the intrusion event. Lecor's intelligent digital signal processing technology (DSP) provides users with real-time adaptive discrimination thresholds to adapt to intruders passing through the infrared detection area at different rates. The detection performance is far better than the preset fixed judgment threshold. The detector, as shown in Figure 2.
Products using digital signal adaptive threshold detection technology include: RK315DT outdoor detector, RK200DT industrial ceiling sensor, RWT92P wireless passive infrared detector, etc.
Island Light is a type of Pendant Light commonly used over the central island in a kitchen or over a long table in a dining room. It typically has multiple bulbs to provide sufficient light to illuminate the entire area. Island Lights come in a wide variety of designs, ranging from traditional pendant styles to modern, industrial, or artistic designs. Island Lights not only provide light but can also serve as a decorative element in a room.
Chandelier Light is a commonly used lighting decoration on the island of a restaurant, which can not only meet the lighting function, but also serve as the main focal point decoration of the restaurant. The Island Light is made of a variety of materials, such as crystal, glass, metal, etc., and has a variety of design styles, which can be matched according to your preferences and the overall style of the restaurant. As a rule of thumb, a gap of 72 cm to 90 cm between the edge of the Lighting Fixture and the surface of the island is optimal. Small islands (1.2 to 1.5 m long) are usually suitable for two medium-sized Island Light or a large Island Light. As for the larger islands, three medium-sized or two larger Island Light can be handled.
