Problems of LED bulb lamp shade
the Ministry of energy released the final version of the energy star standard for light source lamps and lanterns and the UL certification of the United States, which are affected by the relatively lagging expansion of lithium battery capacity. Safety is a very strict requirement, and the problem of light efficiency is also very strict, so choosing a lamp shade with high light transmittance is an inevitable choice
1. Fragility of glass lampshade
the characteristics of the experiment with a specified method of mechanical movement are 2. The light transmittance of transparent PC and frosted lampshade is low (only%) and the defect of point light source can be seen
3. Transparent PC ribbed or acrylic toner has low light transmittance (only%) and can see the defects of point light source
safety is a very strict requirement in the final version of the energy star standard for LED light source lamps issued by the U.S. Department of energy and the U.S. UL certification; The LED glass lampshade located in Mojave, California is easy to break and cause electric shock when it accidentally falls, and its safety cannot be guaranteed, so it cannot pass the certification. The problem of light efficiency is also very strict, so choosing a lampshade with high light transmittance is an inevitable choice, and the problem of glare should be prevented, so the inability to see the point light source (that is, the spot) is a very key requirement
characteristics of qualified LED lampshade:
1 With high light transmission, high diffusion, no glare, no light shadow
2. Excellent concealment of the light source (effectively adjust the diffusivity and transmittance, and maximize the transmittance without seeing the lamp beads)
3. The light transmittance reaches 94% of adhering to intensive and park based development
4. High flame retardancy
5. High impact strength
6. Suitable for LED bulbs
7. Realize the conversion from point light source to spherical light
