Low-carbon, environment protection is widely considered in production design and daily life. Use a Light Guide Film<\/a> (LGF<\/a>) in your dome array<\/a> will save LED quantity to save power consumption. This is why in recently years most of metal dome array<\/a> in your cell phone will use LGF<\/a>.<\/p>\n

As most of LED viewing angle is 100-150 Degree and limited to light irradiation rang, even there\u2019re light on the whole\u00a0dome array<\/a> area, but the light will be focused on certain area, the area around LED is more bright than other area. You can see from below picture.<\/p>\n

So you need to have a extra tooling to diffuse the light to make the it more well-distributed, then a light diffuser is very useful in that situation.\u00a0Or you can call it \u201clight masking paper\u201d.<\/p>\n

You can see this picture showing there\u2019s a piece of light diffuser above each LED and the light irradiation is much better now.<\/p>\n

Oooh, you will say \u201cSo great\u201d. Maybe you want to know what is made from. In fact, it\u2019s very simple. It is a kind of single sided adhesive peel-off tape with two different colors on top and bottom sides.<\/p>\n

The side with adhesive which stick on dome array is white (white is a good reflector), and another side is black (black will not disturb or affect the light irradiation). Here are pictures of them.<\/p>\n

Top Side<\/p>\n

The raw material of this light diffuser is a whole sheet so you need to divide it into several small pieces with the size you need. You just peel-off one small of them and put on LED with light press, it\u2019ll be stick firmly on light guide film<\/a> of dome array<\/a>. Very easily!<\/p>\n

Normally we will not provide the light diffuser along with the LGF<\/a>, so if you need them, please talk with us when you order LGF dome array<\/a> with us and we will do it for you.<\/p>\n
