On June 10th, distributed wireless telemetry, remote control and remote control system consisting of data transmission, spread spectrum power carrier communication technology, computer intelligent information processing and energy-saving electrical control technology to realize intelligent lighting equipment control. Cheng Guobin said that the intelligent lighting control system consists of intelligent lighting, control network and control interface, and the three components are indispensable. Among them, the smart luminaire is composed of a wireless module, an LED driver and an LED luminaire. At the same time, he also introduced that safety certification is a key certification for lighting equipment. Compared with ordinary lamps, smart lamps have stricter safety certification. The safety certification of common luminaires generally includes: structural requirements, including the replacement of light sources, temperature requirements, protection against electric shock, mechanical safety and radiation safety, including optical radiation and electromagnetic radiation, while smart luminaires are added on this basis. Safety and functional requirements for wireless modules and control switches. The RED directive is richer in content and will completely replace the RTTE Directive. Cheng Guobin said that the current instructions for smart lighting product certification include the RTTE Directive and the Radio Equipment Directive. RTTE Directive 1995/5/EC is applicable to wireless and telecommunications terminal equipment, and in addition to the legislative framework update, Radio Equipment Directive 2014/53/EC has many more changes in coordination standards, which will completely replace RTTE Directive. instruction. Next, he compared the RED instruction with the RTTE Directive. According to Cheng Guobin, similar to the RTTE Directive, the Radio Equipment Directive also includes testing requirements for security, electromagnetic compatibility, and radio frequency, and still uses the DoC authentication method. Radio Equipment Directive is still tested according to harmonized standards, internal process control, and is still reviewed and evaluated by NB. However, the Radio Equipment Directive directive is only available for wireless products, and it no longer includes certification for telecommunications terminal equipment. At the same time, the transmission products covered by the RED Directive include wireless communication and wireless detection (radar, RIFD, motion detection, speed detection, etc.), while non-wireless communication and wireless detection products such as ISM products are excluded from the instruction. . In addition, the RED Directive retains products that only receive functionality in the receiving products covered by RED, which were previously included in the EMC LV Directive. In addition, the RED Directive covers a wider range of frequencies. The RTTE Directive covers a range of frequencies from 9 KHz to 3000 GHz, while the RED Directive covers a range of radio frequencies up to 3000 GHz with no frequency lower limit requirements, but there are currently no frequency allocation and coordination standards below 9 KHz. Cheng Guobin reminded that the frequency of smart lighting products must be guaranteed to be certified in at least one EU country, otherwise it cannot be CE certified. Intelligent lighting is on the rise, TUV Nande provides one-stop service At present, the smart lighting market is booming, and various manufacturers have also launched various intelligent lighting products. According to Cheng Guobin, TUV SÃœD provides a comprehensive and comprehensive service content for security lighting products, including safety testing, EMC electromagnetic compatibility testing, chemical testing, energy efficiency/performance testing, individual testing, performance new standard testing, etc. A series of projects.
