LED intelligent lighting 24g radar module garage induction lamp application

2023-02-27 514

LED intelligent lighting 24g radar module garage induction lighting application 10 advantages, as we all know, for the traditional underground garage lighting, LED microwave radar induction garage lighting has many advantages, the traditional lighting will always be lit, leading to no people will consume electricity, forming a huge waste. LED intelligent lighting 24g radar module can automatically light up the lamps, no one lights up or off, saving energy.

LED intelligent lighting 24g radar module garage induction lamp application

Because the underground garage is a public building with a large space, if the single light switch control is used, it will be very inconvenient, and the lamps and lanterns will cause a huge waste for a long time. The centralized or distribution, multifunctional automatic control system should be used. First, the contactor is installed on the lighting circuit to control each electric street lamp through the control circuit. The secondary circuit uses simple relays and photoelectric relays to control each circuit according to the needs of the owner, so as to achieve the effect of automatic control of the lamp.


The other is to use intelligent lighting control system, intelligent lighting control system is to install intelligent control module in the outgoing circuit of the lighting distribution box. The advantages of LED intelligent lighting 24g radar module induction:


LED light source has the advantages of high luminous efficiency, long service life, energy saving and environmental protection. In addition, LED lighting has the advantages of fast response speed and fast control, so that LED lighting and 24g radar induction clever combination, better and effectively meet the lighting energy saving requirements of underground garage.


LED intelligent lighting 24g radar module The product adopts the principle of Doppler effect and transmits electromagnetic waves through a flat antenna. When the moving object enters the electromagnetic wave environment, the waveform is reflected and folded. When the planar antenna receives the feedback waveform, the subsequent circuit generates bright or bright double brightness effect by detecting the trigger signal, and the energy-saving effect is more than 85% than that of ordinary fluorescent lamp.


Service life is greatly extended. Compared with human heat-release induction and voice-controlled induction, the induction distance is longer, the Angle is wider, there is no dead zone, can penetrate glass and sheet metal, and is not affected by the environment, temperature and dust. At 37 degrees, the sensing distance does not shorten.


As a technology enterprise integrating R&D, production and sales, it specializes in the production of LED intelligent lighting 24g radar module, radar sensor, WiFi Bluetooth module and other products. The company is committed to the research of environmental lighting, constantly update knowledge, improve technology, pay attention to talent training, so that our products in quality, comfort and cost continue to achieve a more perfect combination. The company's perfect combination of products and the spirit of unremitting pursuit of product quality has been widely recognized by the industry and users of the favor.


Nowadays, more and more smart devices appear in our life. Many people are even used to this, but in fact, there is a lot of technology behind them. For example, sensor lights in hallways and streets light up whenever someone passes by. Behind the technology is the support of sensors, such as the 24g radar module.


To find out more about the current state of the radar market, we found a radar module manufacturer for an in-depth interview and learned a lot of inside information that was previously unknown to most people in the radar industry.


Radar is better, but why infrared? Generally speaking, the sensors that want to realize lighting and electrical control mainly include infrared sensors, radar sensors, ultrasonic sensors, image sensors and real sensors, the commonly used are infrared sensors and radar sensors.


According to the manufacturer, the infrared sensor mainly receives the infrared changes from the human body through the pyroelectric element, which triggers the subsequent circuit work. The advantage is that the price is cheap, most of them are only a few yuan. But the disadvantage is short range, low precision, easy to be disturbed by the external environment and temperature. Infrared sensing, for example, basically doesn't work in the summer sun.


24g radar module induction is based on the principle of using the Doppler effect, which has the advantage of being able to penetrate glass and thin walls, so the radar sensor can be installed inside the device, making it more design-friendly. At the same time, temperature has no effect on the sensitivity of the radar sensor, which is suitable for corridor and toilet lighting. Since radar induction has so many advantages, why the market is still dominated by infrared induction today.


There are two main reasons for this, it was revealed. On the one hand, infrared induction, which has been in development for decades, is relatively mature and has low power consumption. A small button battery can last for months and it will take time to fully replace it; Another, more important reason is cost. Even if the performance is better, the cost aspect, even the 5.8GHz radar price is generally around 10 yuan, there is a certain distance from infrared.


It should be noted that before 2015, the domestic commercial 24g radar module induction market was almost a blank, starting late. Combined with some shortcomings of the current radar, the market capacity is not big. According to the company, the current overall market demand in tens of millions of levels, many enterprises have entered this market. If we only look at the application scenarios of corridor lighting, street lamps and toilet lights, the living environment is not optimistic.


In terms of talent, many companies do not have antenna simulation engineers or algorithm engineers, which is difficult for the development of radar modules. Especially before 2015, there were almost no antenna simulation engineers in China, and now almost all engineers are trained by enterprises themselves, which also leads to the slow development of the domestic 24g radar module market.


The future of Radar


Currently, domestic radar frequency bands are available for free at 5.8GHz, 24GHz, and 77-79GHz, while other frequency bands are not available for free. If you want to use others, you need to apply to the relevant authorities. At present, the small-scale audit of the domestic wireless frequency band is relatively loose, but once it is strict, there will be some trouble.


As for the choice of frequency bands, companies revealed that either low frequency bands such as 5.8GHz, which can make the cost lower and reflect the performance advantage of radar, or choose to make 24GHz products, which can make the performance better.


Just like the MCU market, most of it is now 8-bit or 32-bit, and there are very few vendors who choose to do 16-bit MCUS, and so is Radar.

Usually, many manufacturers choose 5.8GHz, 24GHz and 77GHz, which makes the application scenarios of radar induction relatively narrow, such as induction lights in residents' life scenes, induction lights in underground parking lots, and monitoring equipment in corridors. In the future, with the development of induction technology, smart home, smart hotel and other fields will have greater space for development.
