At present, the maximum width of the light guide plate can reach 2000mm, the length is up to 4000mm, and the thinnest thickness is only 2mm. The larger the size, in order to ensure the brightness, the thickness should be correspondingly increased, and the light guiding effect is correspondingly reduced, and the thickest light guide plate does not exceed 20 mm.
Care should be taken when processing the light guide plate to prevent scratches. The light guide plate should maintain the integrity of the wrapping paper during cutting and polishing. When the light guide plate is polished, the slits such as residual debris or dust may affect the light guiding effect. The reflective paper on the back is packaged as a whole with the lamp, and the light guiding effect is better. The length of the light guide plate on one side of the lamp tube is preferably equal to or slightly longer than the length of the lamp tube; if the lamp is tested, it is significantly shorter than the light guide plate.
The light guide plate is tested with a genuine light source; the brightness and color of the light source also affect the light guiding effect. When there is no background color when illuminating, it is judged directly by the naked eye that the light guiding brightness of the square illuminating plate will cause a large deviation. Because the raw material of Fanghao light guide plate is imported color concentrate MMA plate colorless and transparent. The naked eye can't directly sense its true brightness. It is recommended to use a illuminometer to test or put a light box to judge its brightness.
