1. Field of the Invention
The invention relates to a lamp assembly that has a relatively high light-emitting efficiency.
2. Description of the Related Art
As shown in
Therefore, the object of the present invention is to provide a lamp assembly that has a relatively high efficiency and an even brightness of light output.
Accordingly, a lamp assembly of the present invention comprises a light source, a shell wall, and a reflecting unit. The shell wall defines a receiving space that retains the light source therein, and has a central wall unit and a pair of extending wall segments. The central wall unit has a base wall segment and a pair of connecting wall segments. The base wall segment is mounted with the light source, and has side ends opposite to each other in a left-right direction, and longitudinal ends opposite to each other in a front-rear direction transverse to the left-right direction. The connecting wall segments extend respectively from the longitudinal ends of the base wall segment. Each of the connecting wall segments has a distal end. The distal ends of the connecting wall segments are opposite to each other in the front-rear direction. The extending wall segments extend respectively from the side ends of the base wall segment, interconnect the connecting wall segments and cooperate with the connecting wall segments to define an opening in spatial communication with the receiving space. Each of the extending wall segments has a distal end. The distal ends of the extending wall segments are opposite to each other in the left-right direction. A distance between the distal ends of the connecting wall segments is larger than that between the distal ends of the extending wall segments. The reflecting unit includes a plurality of first reflecting members configured to be convex and protruding inwardly from the extending wall segments, and a plurality of second reflecting members configured as prisms and protruding inwardly from the central wall unit. Light generated from the light source toward the shell wall is reflected by the first and second reflecting members and emitted out of the shell wall through the opening.
Other features and advantages of the present invention will become apparent in the following detailed description of the preferred embodiments with reference to the accompanying drawings, of which:
Before the present invention is described in greater detail, it should be noted that like elements are denoted by the same reference numerals throughout the disclosure.
As shown in
The shell wall 23 has a central wall unit 230 that has a base wall segment 231 and a pair of connecting wall segments 233. The base wall segment 231 is mounted with the light source 21, and has side ends 2311 opposite to each other in a left-right direction (L), and longitudinal ends 2312 opposite to each other in a front-rear direction (F) transverse to the left-right direction (L). The connecting wall segments 233 extend respectively from the longitudinal ends 2312 of the base wall segment 231. Each of the connecting wall segments 233 has a distal end. The distal ends of the connecting wall segments 233 are opposite to each other in the front-rear direction (F). The shell wall 23 further has a pair of extending wall segments 232 that extend respectively from the side ends 2311 of the base wall segment 231, that interconnect the connecting wall segments 233, and that cooperate with the connecting wall segments 233 to define an opening 234 in spatial communication with the receiving space 239. Each of the extending wall segments 232 has a distal end. The distal ends of the extending wall segments 232 are opposite to each other in the left-right direction (L). A distance (D1) between the distal ends of the connecting wall segments 233 is larger than a distance (D2) between the distal ends of the extending wall segments 232.
As further shown in
Although the connecting wall segments 233 are located farther from the light source 21 compared to the extending wall segments 232, the prismatic configuration of the second reflecting members 242 would increase the reflection of the light projected from the light source 21 toward the connecting wall segments 233, thereby resulting in even light output of the lamp assembly 2 of this invention.
