DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
The present invention aims to provide a lamp set with changeable cubical angle of projecting light beam. Six embodiments are provided below to facilitate discussion. First, 25 please refer to FIGS. 1 through 4 for a first embodiment. As shown in FIGS. 1 and 2, the lamp set with changeable cubical angle of projecting light beam includes a lamp set body 11, a light emission element 12, a light projection element 13, an installation element 14 and an operation mask 15. More specifically, the lamp set body 11 has a hollow housing space 111 inside, an opening 112 communicating with the housing space 111, at least one coupling portion 113 located in the housing space 111, at least one first assembly portion 114 encircled the opening 112, and at least one first confining to portion 115 located in the housing space 111 in a spaced manner. The light emission element 12 is installed in the lamp set body 11, and includes a cooling element 121 installed on the coupling portion 113, and a light generation source 122 located on the cooling element 121 and faced the opening 112.
The light generation source 122 is connected to an electric source to get electric power and emit light toward the opening 112. Hence the light generation source 122 forms a light exit plane 123 at one side facing the opening 112 as shown in FIG. 5. Furthermore, after the light generation source 122 has gotten the electric power, aside from providing the light, it also generates waste heat which is dispersed by the cooling element 121 to reduce the temperature of the light generation source 122. The light generation source 122 in this invention can be selectively a LED, a lighting bulb or a lamp tube. The light projection element 13 is located corresponding to the opening 112, and includes a light receiving plane 131 spaced from the light exit plane 123 at a light receiving distance 100 to receive the light, and a light projection plane 132 connected to the light receiving plane 131 to transmit the light and project the light outside the housing space 111. The light projection plane 132 projects the light at a projecting light beam cubical angle R in a direction remote from the opening 112 as shown in FIG. 6. In addition, the light projection element 13 can be a piano-convex lens.
Please referring to FIG. 5, the installation element 14 is located in the housing space 111, and includes at least one second connecting portion 141, an aperture 142 formed in the middle of the installation element 14 to hold the light projection element 13, a reflective plane 143 faced another side of the light exit plane 123 and installed between the second connecting portion 141 and the aperture 142 to surround the light projection element 13, at least one second confining portion 144 spaced from the second connecting portion 141, a plurality of latch portions 145 located between the aperture 142 and the second connecting portion 141 and extended in a direction remote from the reflective plane 143, and a confining element 146 fastened to the latch portion 145 to confine the light projection element 13 in the aperture 142. In addition, the operation mask 15 includes a second assembly portion 151 coupled with the first assembly portion 114 and slidable thereon, at least one first connecting portion 152 extended toward the housing space 111 and movably connected to the second connecting portion 141, and a light permeable sheet 153 corresponding to the light projection plane 132 of the light projection element 13 to allow the light to pass through. The first connecting portion 152 can be a boss, preferably includes two sets in actual implementation, while the second connecting portion 141 can be a slant track, but this is not the limitation of the invention. In other to embodiments the first connecting portion 152 can be a slant track, while the second connecting portion 141 can be a boss.
Furthermore, the second connecting portion 141 can be implemented in two fashions. In the first fashion, the second connecting portion 141 has a smooth slide edge so that the second connecting portion 152 can smoothly slide on the second connecting portion 141, as shown from FIG. 1 to FIG. 3B. In the second fashion, the second connecting portion 141 has a plurality of positioning adjustment teeth 147; hence the first connecting portion 152 does not smoothly slide on the second connecting portion 141, but automatically falls between the positioning adjustment teeth 147, therefore the installation element 14 and the operation mask 15 form stepping movement between them and also form mutual positioning at the same time, as shown in FIG. 4.
In addition, the first confining port ion 115 of the lamp set body 11 and the second confining portion 144 of the installation element 14 can be coupled with each other to guide movement of the installation element 14. Each first confining portion 115 and each second confining portion 144 have two implementation fashions. In the first fashion, both the first confining portion 115 and the second confining portion 144 have respectively a smooth slide surface formed thereon so that they can slide smoothly relative to each other, as shown in FIGS. 1 through 3B. In the second fashion, each to first confining portion 115 has a plurality of confining bosses 116, while each second confining portion 144 has a plurality of confining teeth 148; hence when the first confining portion 115 and the second confining portion 144 slide against each other in a contact manner the confining bosses 116 are movably latched on the confining teeth 148 so that the installation element 14 and the lamp set body 11 form stepping movement between them, therefore can confine the relative movement amount between installation element 14 and the light emission element 12 at the same time, as shown in FIG. 4.
In the first embodiment of the lamp set of the invention, the first connecting portion 152 of the operation mask 15 is extended to an allowance space 16 formed between the installation element 14 and the lamp set body 11, as shown in FIG. 5. In a second embodiment of the lamp set of the invention, the first connecting portion 152 is extended to one side of the installation element 14 facing the light projection element 13. In other words, the installation element 14 is located between the first connecting portion 152 and the lamp set body 11, as shown in FIG. 6.
The first embodiment and the second embodiment of the invention are operated in a same fashion, hence only the first embodiment is discussed herein as shown in FIGS. 2 through 3B. First, it is to be noted that the operation mask 15 merely to swivels against the lamp set body 11, but does not move against it in other manner. When a user performs an adjustment measure to make the operation mask 15 to turn against the lamp set body 11 and the installation element 14 for a swivel displacement, the second assembly portion 151 of the operation mask 15 slides against the first assembly portion 114 of the lamp set body 11; meanwhile, the first connecting portion 152 of the operation mask 15 slides on the second connecting portion 141 of the installation element 14, and pushes the installation element 14 to move in a movement displacement so that the installation element 14 is moved forward or backward against the light emission element 12, thereby change the light receiving distance 100 between the light emission element 12 and the light projection element 13. In other words, after the installation element 14 has been moved the object distance of the light emission element 12 relative to the light projection element 13 changes, as a result, the light projection plane 132 of the light projection element 13 projects the light at varying projecting light beam cubical angles R. In addition, when the installation element 14 is moved against the lamp set body 11 and the operation mask 15 the second connecting portion 141 with the positioning adjustment teeth 147 can make the installation element 14 and the operation mask 15 to move in a stepping manner, and also form mutual positioning between the installation element 14 and the operation mask 15 at the same time, as shown in FIGS. 4 and 5. And through the confining bosses 116 on each first confining portion 115 and the confining teeth 148 on each second confining portion 144 the installation element 14 can be confined and guided to make movement, thereby move steadily forward or backward against the lamp set body 11 while the operation mask 15 proceeds the swivel displacement, and also form mutual positioning between the installation element 14 and the lamp set body 11 at the same time, as shown in FIG. 4.
FIGS. 7 and 8 illustrate respectively a third embodiment and a fourth embodiment of the invention. They are substantially same as the first embodiment and the second embodiment previously discussed.

The light emission element 22 is located in the lamp set body 21, and includes a cooling element 221 and a light generation source 222 located on the cooling element 221 and faced the opening 212. The light generation source 222 is connected to an electric source to get electric power and emit light toward the opening 212. Hence the light generation source 222 forms a light exit plane 223 at one side facing the opening 212. The light projection element 23 is located corresponding to the opening 212, and includes a light receiving plane 231 spaced from the light exit plane 223 at a light receiving distance 200 to receive the light, and a light projection plane 232 connected to the light receiving plane 231 to transmit the light and project the light outside the housing space 211. The light projection plane 232 projects the light at a projecting light beam cubical angle in a direction remote from the opening 212.
Same as previously discussed, the installation element 24 is 25 located in the housing space 211 to hold the light emission element 22, and includes at least one second connecting portion 241 and an aperture 242 formed in the middle of the installation element 24 to hold the light emission element 22. In addition, the operation mask 25 includes a second assembly portion 251 coupled with the first assembly portion 213 and slidable thereon, at least one first connecting portion 252 extended toward the housing space 211 and movably coupled with the second connecting portion 241, a light permeable sheet 253 corresponding to the light projection plane 232 to allow the light to pass through, and a reflective element 254 to hold the light projection element 23. The first connecting portion 252 can be a boss, preferably includes two sets in actual implementation., but this is not the limitation of the invention.
