First, the choice of led lighting lamps and lanterns
1, packaging and trademark.
The state forces LED lamp manufacturers to mark the following contents on the product packaging: rated voltage, voltage range, rated power and rated frequency. Generally speaking, the trademark printing quality of high-quality products is good, the logo is clear and identifiable, and it is not easy to erase with soft wet cloth, with the manufacturer's trademark and related certification marks. When choosing a product brand, we should choose a manufacturer with a certain reputation and a registered capital of more than 50 million. The LED lamp beads produced by different manufacturers have different production standards, different manufacturing processes and different employee operations, and there will be obvious differences.
2. The appearance of the lamp.
Appearance should be free of cracks, looseness and pry marks between interfaces. During installation and disassembly, the lamp holder should not be loose or bent. The plastic shell of the lamp must be engineering plastic flame retardant.
Its characteristic is that the surface has a texture similar to ground glass. Ordinary plastic has a smooth and shiny surface, but it is easy to deform and flammable, so it is forbidden to be used in the production of energy-saving lamps. 3. Working status.
Under normal working conditions, the temperature rise of LED lamps should be relatively low. If the heat dissipation condition is not good, the lamp bead will work at high temperature, and the light attenuation will be great, and the life of the lamp will be greatly reduced. At the same time, if the light flashes quickly when it is switched on and off, it also indicates that there is a quality problem.
Second, the development of LED

Third, the market dynamics of LED lamps
In the first stage, LED lights replace the acceptance stage.
Consistent with the use of traditional light sources, LED lamps are characterized by low carbon, environmental protection, energy saving, long service life and easy to be accepted by the market. Especially in commercial occasions, the emphasis is on product quality advantages.
The second stage is the practical model stage of LED lamp.
On the basis of the previous stage, the market has a certain recognition and acceptance of LED lamps. Other characteristics of LED lamps, such as environmental protection, small size and high reliability, are gradually becoming prominent. There will also be greater and wider development and application space in the lighting industry. Light sources are no longer just for lighting. With people's increasing attention to urban cultural construction, lighting has been placed on the streets to beautify the city.
Therefore, manufacturers pay attention to the advantages of design and application. The third stage is the intelligent control stage of LED lights.
With the development of new technologies such as networking, LED, as a semiconductor industry, will also catch this high-speed train and exert its high controllability. From home to office building, from road to tunnel, from car to walking, from auxiliary lighting to main lighting, intelligently controlled LED lighting system will bring higher-level services to mankind. The LED lighting industry will also go through the process of making products, designing products and providing overall solutions.
Due to the multiple characteristics of LED, we are full of expectations for its bright future, but we should not avoid some shortcomings at present. In the early stage, LED lamps were in the early stage of development. Because the product has various functions, the price is higher. Ordinary incandescent lamps are very cheap, and there is a transition period for ordinary people to accept the price gap. So, in the early days,
Mainly used in commerce, markets and streets. The above detailed introduction of led lighting gives us a reference for the selection of led lighting. We can also use these skills when choosing led lighting to add a gorgeous and practical led lighting to our home.
