What are the lampshades of LED lamps?

1) The fragility of the glass lampshade;

2) The transparent PC plus frosted lampshade has low light transmittance (only 80-89%) and the defect of the point light source can be seen ;

3) Transparent PC with ribs or acrylic with toner has low light transmittance (only 80-89%) and defects of point light source can be seen;

The U.S. Department of Energy has released the final version of the Energy Star standard for LED light source lamps and the U.S. UL certification. Safety is a very strict requirement; then

The lampshade of the LED lamp is made of glass, so it is easy to drop it accidentally. If broken, it may cause electric shock. Safety cannot be guaranteed, so the certification will fail.

The issue of light efficiency is also very strict, so choosing a lampshade with high light transmittance is an inevitable choice, and it is also necessary to prevent glare problems, so it is very important that the point light source (that is, the light spot) cannot be seen. Key requirements.

Characteristics of qualified LED lamp shades:

1) High light transmittance, high diffusion, no glare, no light and shadow;

2) Suitable for LED lamps The use of;

3) Realize the conversion of point light source into spherical light

4) The light source has excellent concealment (effectively adjust the diffusion rate and light transmittance, and the light cannot be seen) The light transmittance reaches the maximum under the premise of beads);

5) The light transmittance reaches 94%;

6) It has high flame retardancy;

7 ) has high impact strength;

Whether the LED lamp shade is qualified is not as simple as a few strokes. It is related to the safety of electricity in people's daily life and

safety Hidden danger. Using LED lampshades with qualified standards is a spontaneous means for us to protect our own safety.
