　　Principle of industrial RFID identification system

　　A complete RFID system consists of reader, RFID tag and computer system.

　　Reader is a key part of RFID system, which is mainly composed of wireless transceiver module, antenna, control module and interface circuit. These readers can write and read the information in RFID tags, and they are an important part of the data acquisition terminal in RFID system. The reader communicates with the RFID tag through the wireless transceiver module, the control module is responsible for processing instructions and data, and the interface circuit is used to connect the reader and the computer system.

　　RFID tag is a data carrier used to mark the object to be traced, which records data information and can read and write with RFID reader. Tag antenna and tag chip are the core components of RFID tag. The tag antenna is used to receive the signal sent by the reader and transmit it to the tag chip, which is used to store and process data information. By interacting with the reader, the RFID tag can automatically identify objects and transmit data information.

　　The computer system includes PC or PLC and other controllers, and even WMS, MES, ERP and other systems at the user’s site, which are used to receive the information fed back by RFID readers. This information can include data of the object to be traced, identification results, statistical data, etc.

　　In a typical RFID system, the computer system, reader and RFID tag cooperate with each other to complete the tasks of automatic identification, data acquisition and transmission. By using RFID technology, the accuracy and efficiency of data acquisition can be improved, the cost can be reduced and the work efficiency can be improved.

　　Application advantages of industrial RFID identification system

　　In the industrial production environment, data recognition technology plays a vital role. At present, barcode, QR code and RFID technology are commonly used data identification technologies in industrial scenes. However, each technology has its specific limitations. For example, although bar code technology is widely used, it needs to match a specific light source when reading data, and it has high requirements on the brightness of the light source. In addition, it needs to be scanned by the scanner aiming at the light in the visible range in order to read the information successfully. This technology requires high mechanical accuracy. Once the objects bearing bar codes such as trays are deformed, the bar codes may not be recognized. In addition, barcode recognition can only be scanned one by one, and only one barcode can be read at a time, which greatly reduces the work efficiency. Moreover, because the bar code is easy to wear and dirty, its service life is short, and it cannot be reused after being modified.

　　On the other hand, although the two-dimensional bar code provides a solution in terms of information capacity and adds the function of information error correction, it can realize the functions of reading and anti-counterfeiting on the surface of articles through laser engraving technology, but there are still some disadvantages. For example, its application scenarios are relatively limited, which can not fully meet the needs of complex application scenarios in industrial production.

　　To sum up, although barcode, QR code and RFID technology have played an important role in industrial data identification, they all have certain limitations. Therefore, it has become an urgent problem to find a more efficient, reliable and adaptable new data identification technology in the industrial field.

　　LED car lights are suitable for various lighting applications in automotive electronics, including headlights (high beam and low beam), fog lights, tail lights, brake lights, turn signals, daytime running lights, pedal lights, instrument lights, license plate lights, door lights, interior lights, width lights, navigation, entertainment systems, backlights and indicator lights. Compared with traditional light sources, LED light sources have large differences in physical size, luminous flux, spectrum, and spatial distribution of light intensity. Therefore, LED detection cannot replicate the standards and methods of traditional light source detection.

　　What Are the Most Common Detection Technologies for LED Headlights?

　　Detection of optical parameters of LED lamps

　　1. Luminous intensity detection

　　Light intensity is the strength of light, which is the amount of radiated light within a certain angle range. Since LED light is relatively concentrated, the inverse square law does not apply at close distances. Therefore, the CIE127 standard stipulates that the conditions for measuring light intensity are A (far-field conditions) and B (near-field conditions) for measuring the average normal light intensity. The detector area for both conditions is 1cm2. Generally, standard condition B is used to measure luminous intensity.

　　2. Luminous flux and light efficiency detection

　　Luminous flux is a physical quantity that measures the total amount of light emitted by a light source. It represents the sum of the light energy emitted by the light source in all directions. There are two main methods for detecting luminous flux:

　　Integral method: Light the standard lamp and the lamp under test in the integrating sphere in turn, and record their readings on the photoelectric converter as Es and ED respectively. The luminous flux of the standard lamp is known as Φs, then the luminous flux of the lamp under test ΦDED〜Φs/Es. The integral method uses the principle of “point light source” and is simple to operate, but it is affected by the color temperature deviation between the standard lamp and the lamp under test, and the measurement error is large.

　　Spectrophotometry: This method calculates the luminous flux by measuring the spectral energy distribution of the light source \( P(\lambda) \). Use a monochromator to measure the spectral energy of the standard lamp in the wavelength range of 380nm to 780nm on an integrating sphere, and then measure the spectral energy of the lamp under test under the same conditions. By integrating these spectral energy values, the luminous flux of the lamp under test can be obtained.

　　Luminous efficiency is a parameter that describes the efficiency of a light source. It is defined as the ratio of the luminous flux emitted by the light source to the electrical power it consumes. For LED light sources, constant current is usually used to measure luminous efficiency to ensure the accuracy and repeatability of the measurement.
