At present, the development of specialty stores, hardware stores, hypermarkets and lamp cities is not satisfactory due to the physical channel and dealer agency mode. Under the impact of e-commerce, LED lamps for classroom lighting surge under the impact of the Internet, which reduces the overall profit and muddles the product quality. The progress of semiconductors and the Internet has brought great changes to the lighting industry and LED lamps develop rapidly, The lighting industry has undergone a revolution and spread rapidly all over the country.
The reform and development of LED lamps used in school classrooms has gone through three ways:
First, technically, the lamp body material is made of profile, die-casting, guide, thermoplastic, ceramic, ordinary plastic + aluminum, and the light effect is 100 lumens per watt. Resistance capacitance, non isolation, isolation, linear constant current and other driving modes are used. At the initial stage of technology, the shape is mainly to imitate the traditional light source and photoelectric parameters. The price of LED lamps for school classroom lighting is relatively high and the market demand is not much.
The second is the development of lamp body heat dissipation to heat sink + ordinary plastic. The light efficiency slowly reaches 200 lumens per watt, which is slowly coordinated with the traditional dimmer. The application of lamps and lanterns is gradually popularized in the market, wireless intelligence is developing, and LED tubes for school classroom lighting are exploring on the road of intelligence.
Third, the national standards and guidelines for the upstream and downstream markets of LED light sources and LED lamps have been issued, and the LED light efficiency has also reached 300 lumens per watt. Active signal transmission and feedback reception, passive signal reception and identification, intelligent control, from one-way communication to two-way interaction of lighting system. From the light effect, color selection, switching habits, anti-theft and alarm clock functions, LED lamps in the field of architectural lighting have more development potential. The integration of lighting products into mobile phone intelligence will become a trend. Lighting products will be converted from a single hardware platform to hardware + software system components, which are compatible with software. Around the characteristics of LED lighting, manufacturers of different brands will develop different lighting lamps to meet the needs of consumers. It integrates lighting, safety monitoring and data information transmission functions. Lighting brand enterprises, lighting engineering companies, professional manufacturing companies, professional material supporting companies and professional e-commerce lighting + logistics companies will be more subdivided. They are developing differently in the Internet society and semiconductor lighting structure
