How To Know Deeply With Light Guide Plate Materials

1) LED light guide product introduction:

1. Ultra-thin design can meet different space design and environmental requirements, and can meet the requirements of different places;
2. the light is soft and even, anti-glare and glare, long-term work or use is also relatively difficult to fatigue;
3. energy saving, environmental protection; low light decay, long service life, no pollution;

4. Light guide plate must have a protective film before testing the uniformity of the light guide plate to prevent the light guide plate from being scratched, which can effectively resist fingerprint invasion, and the finger slips over without leaving marks; even if it leaves liquid residue such as sweat, The hand can be cleaned with a light wipe to ensure that the light guide plate does not appear bright.

5. Test the uniformity of the light guide plate, put reflective paper under the light guide plate, you can use it to fill light and collect light; test the light guide plate uniformity more accurately.

2) Light guide plate application notes:

1. The surface hardness of the light guide plate is equivalent to aluminum (softer), so attention should be paid to the surface protection when picking and placing. If it is damaged, it will be polished with the abrasive used for yellow aluminum, which is easy to restore the original beautiful surface. Acrylic has a relatively large coefficient of thermal expansion, and its degree of expansion is about several times that of metals. When the device is fixed or fixed, temperature changes should be considered, leaving room for expansion and contraction.

2. The light guide must be safe during the installation process.

3. After removing the protective film on the light guide plate, avoid touching the light guide plate with wet hands or sweat hands;

4. The light guide plate has the same expansion coefficient as ordinary plastic. In use, the expansion and contraction caused by temperature change must be fully considered. The temperature of the room should be kept at around 25 °C when all the light guide plates are installed and stored.

5. The change of humidity will also cause the expansion and contraction of the light guide plate. Although the speed of this change is not as obvious as the change caused by temperature, it must be paid attention to when using it. The humidity of the room should be kept at 50- when all the light guide plates are installed and stored. 60% RH.

6. When transporting the light guide plate, avoid rubbing and bumping the surface of the light guide plate; in the place where the original light guide plate is placed, sand particles should be prevented from leaking into the light guide plate; when the light guide plate is cut, the foreign matter on the surface of the cut bed should be cleaned;

7. Avoid wiping the surface of the light guide directly with non-cotton materials.

8. It is recommended to install the light guide plate in the dust-free workshop of class 10W or above; all workers must wear a mask to avoid the saliva sprayed between the light guide plate, the reflection sheet and the diffusion sheet to produce bright spots; in order to protect the hand while also protecting Light guide plate, you must wear powder-free latex gloves when working (do not use other types of gloves), avoid sweat and fingerprints, avoid black and white spots and shadows caused by scratches, to prevent any fingerprints and scratches on the surface of the light guide plate. Traces of injury.

9. Use electrostatic precipitator to remove dust and IPA to clean the surface before assembly to avoid black and white spots.

10. If the product has smudges, sweat and fingerprints, it can be cleaned with IPA and dust-free cloth to ensure that it can be assembled after it is completely dry.

Production size

1. no need for any screen, the maximum width size reaches 1700mm, the length is unlimited;

2. The light guide point can be arbitrarily adjusted according to different requirements of the customer;

3. can be arbitrarily produced conventional and non-conventional size of the light guide plate, no screen fee, the sample time is extremely fast, high production efficiency;
