Abstract: The present application discloses a light-emitting element comprising a semiconductor light-emitting stack emitting a first light which has a first color coordinate, a first wavelength conversion material on the semiconductor light-emitting stack converting the first light to emit a second light, and a second wavelength conversion material on the first wavelength conversion material converting the second light to emit a third light. The first light and the second light are mixed to be a fourth light having a second color coordinate. The third light and the fourth light are mixed to be a fifth light having a third color coordinate, and the second color coordinate locates at the top right of the first color coordinate and the third color coordinate locates at the top right of the second color coordinate.

Abstract: A moisture-absorbable carton includes a carton housing, a plurality of cushions disposed in the carton housing, and at least one moisture-absorbable spacer disposed in the carton housing. The moisture-absorbable spacer and a part of the cushions surround an inner surface of the carton housing for forming an accommodation space, wherein the accommodation space is for stowing at least one protected object. The moisture-absorbable spacer comprises a paper casing and at least one drier bag disposed in the paper casing.

Abstract: A carton includes a top casing and a bottom casing. The top casing includes plural first sidewalls and plural first tongue parts connecting to the first sidewalls. The first tongue stripes parts are used for fixing on the inner surfaces of the adjacent first sidewalls. The bottom casing includes plural second sidewalls and plural second tongue parts connecting to the second sidewalls. The second tongue parts are used for fixing on inner surfaces of the adjacent second sidewalls. The bottom casing further includes plural reinforcing pieces respectively connected to one of the second sidewalls. The reinforcing pieces are disposed at the outside of the second sidewalls. When the top casing is coupled to the bottom casing, the reinforcing pieces are utilized for filling the gap between the top casing and the bottom casing caused by the first tongue parts.

Abstract: A paper packaging box is disclosed. The paper packaging box includes a bottom cover, two side frames, a plurality of first Velcro portions, a plurality of second Velcro portions, and a top cover. The two side frames are respectively disposed standing on two opposite sides of the bottom cover. Each of the side frames has a plurality of slots, and the slots of the two side frames are face to face in pairs. The first Velcro portions are disposed at the bottom cover. The second Velcro portions are disposed at the side frames. The first Velcro portions and the second Velcro portions are engaged with each other to allow the side frames to stand on the bottom cover. The top cover is disposed above the side frames.

Abstract: A packaging box is disclosed, which is formed by coupling two packaging structures. The packaging structure includes a baseboard, which has a first side, a second side opposite to the first side, a third side for connecting the first and second sides, and a fourth side opposite to the third side for connecting the first and second sides. The packaging structure includes a first sidewall standing on the first side, and a second sidewall standing on the third sidewall. The packaging structure further includes plural first coupling elements and plural second coupling elements. The first coupling elements are disposed on the first and second sidewalls. The second coupling elements corresponding to the first coupling elements are disposed on the second and fourth sides of the baseboard. Two packaging structures are coupled by coupling the first coupling elements to the second coupling elements to obtain the packaging box.
