(1) the face shield back side arranges positioning cylinder, coordinates with the positioning round orifice on drain pan, and tolerance clearance (radially) is generally 0.05-0.1mm.Wherein, two reference columns of every face shield operated by rotary motion, these two reference columns are on same level line or same perpendicular line.Yet this locator meams has following deficiency:
1., although face shield generally all adopts identical material to carry out injection moulding with drain pan, due to the structure between them and the very large difference of product thickness existence, so their thermal expansivity is inconsistent, has larger difference; In addition, PCBA(Printed Circuit Board Assembly, finished product wiring board) material and the material of drain pan face shield also different, the thermal expansivity of PCBA plate and drain pan face shield have larger difference.Therefore, at LED, show in the use procedure of module, continuous rising along with temperature, thermal expansion amount between drain pan, PCBA plate, this three of face shield is also different, if the difference of the thermal expansion amount absolute value of any two surpasses the tolerance clearance of face shield positioning cylinder between this three, can limit expansion because of the existence of this reference column on the contrary, very easily cause flower screen phenomenon.
2. if the gap of cylinder, circular hole is larger, when starting to assemble, do not have positioning action at all, be only that mistake proofing effect is installed.
3. owing to being two holes location, and due to the existence of fit-up gap, the object of expanded by heating, when thermal expansion, cannot be determined the benchmark of dilatational strain.
(2) face shield screw hole location, however the screw via hole aperture of face shield centre is suitable with the external diameter of screw, slightly large 0.05-0.1mm.It has following deficiency:
1, because face shield lamp hole is than the large 0.15-0.25mm of lamp, while beating central screw, face shield can not effective location, and face shield is easy to crooked, and the gap between face shield and face shield is inhomogeneous, very easily causes bright concealed wire phenomenon.
2, face shield crooked after, when expanded by heating, be easy to arch camber distortion, cause flower screen phenomenon.
