So more LED bulbs using plastic foam to prevent break. And LED bulbs because the heat from the radiator out, so through the blister of the light are visible light, there is little fever of the infrared, so the use of plastic to do the bubble shell will not be damaged because of the heat can not.

   2. Light source concealment is better (as far as possible can not see LED lamp beads);
   3. Transmittance of more than 90%;
   4. Has a high flame retardant;
   5. Has a high impact strength;
