LENS AND LIGHT EMITTING DEVICE

A lens includes a cover part and an interposing member formed of a light-reflecting material. The cover part includes a lens part having a lateral side, a connection part constituting a lateral side wall extending from the lateral side, and a flange part having a lower surface disposed below the lateral side wall. The interposing member has an upper surface and an inner lateral surface. The upper surface is disposed on the lower surface of the flange part. The lens part and the interposing member define a recess having an opening facing downward. The lens part defines a bottom surface of the recess. The inner lateral surface defines a lateral surface of the recess, which defines the opening of the recess. The flange part extends outward from the opening. The lens part has a convex lens and a light-emitting surface with projections outward from the convex lens.

MANUFACTURING AN ASSEMBLY OF A FIRST AND A SECOND OBJECT
20230241818 · 2023-08-03 ·

A method of manufacturing and assembling a first and a second object wherein the first object is made by bringing a flowable compound into a first object shape and then subjecting the flowable compound to a hardening process that results in a change of a chemical composition of the flowable compound, thereby creating the first object or a part thereof. Then, the first object is positioned relative to a second object, and a flow portion of the hardened article of the modified compound is caused to become flowable by an input of energy. An interpenetration zone of the flow portion and structures of the second object is created, and the flow portion is allowed to re-solidify, whereby the interpenetration zone between the re-solidified flow portion and the structures of the second object secures the first and second objects to each other.

IN-MOLD SPRAYING SYSTEM AND PROCESS METHOD

For in mold spraying, a double-inclined mixing nozzle is connected obliquely and fixedly with a side surface of a third half-mold through a lateral sealing structure and connected with a side surface of a first half-mold in an inclined and sealing manner, side faces of a first half-mold and the third half-mold are respectively provided with installation inclined surfaces. A lateral sealing structure includes a mounting plate and a sealing member. The sealing member is sleeved on the double-inclined mixing nozzle and is in transition fit with the double-inclined mixing nozzle and the mounting plate respectively. A butt sealing groove provided on the installation inclined surface of the first half-mold and is in sealing fit with the mounting plate.
