Light-collecting device
专利汇可以提供Light-collecting device专利检索，专利查询，专利分析的服务。并且PURPOSE:To enable easy detecting of an omnidirectional reference light, by a method wherein, in a collector for controlling a height of a blade of a bulldozer or other equipment, a surface collecting a reference light is formed in a cylinder, and optical fibers are alined. CONSTITUTION:In order to control a height of a blade (a part for scratching earth) of a bulldozer or other equipment, fan beam such as laser rays is projected as a reference light, and a collector 1, mounted to the blade, detects the reference light. One end of each optical fiber 3 peeps out through a surface 2 of a cylindrical collector 1 at given pitches in a peripheral direction. The other end of the optical fiber is led to a collecting element 4. The aligning pitch of the optical fiber of a point on the periphery of the collector decreases the further downward on the periphery this point is situated, and the alining density increases in a manner described above. As a result, as the irradiation position of the reference light is lowered, a detection light increases, and this permits finding of the position. Additionally, the collector is formed in a cylinder, and thereby it may be irradiated with the reference light from every direction.，下面是Light-collecting device专利的具体信息内容。
