Embodiments of the present application relate to the technical field of lamps, and in particular, disclose a photoreceptor mounting base and a lamp. A photoreceptor mounting base includes a housing and a rotation member. The housing is provided with a receiving cavity and an opening that communicates with the receiving cavity. The rotation member is received in the receiving cavity and is rotatably connected to the housing. The rotation member is configured to mount a photoreceptor, and a part of the photoreceptor is exposed to the opening. By means of the preceding modes, the embodiments of the present application can implement: through the rotation of the rotation member, the rotation of the photoreceptor can be implemented; a photoreceptive lens disposed on an exposed part of the photoreceptor can rotate around an axis of the rotation member, so as to implement accurate induction of changing light rays outside by the photoreceptor.

A pointer for a gauge or an instrument cluster assembly is provided. The pointer is formed of a light conducting material. In one form, indicia are disposed about the axis of rotation and/or on a surface, the plurality of indicia configured to be selectively illuminated by the pointer. A second end of the pointer may be configured to be selectively rotated adjacent to each indicium of the plurality of indicia and to illuminate the indicia when the light guide pointer is disposed adjacent to the indicia. The second end may be wider than a first end of the pointer. In some variations, the pointer may have a fan shape, and the indicia may be configured as tick marks defining a bar graph. In some forms, opaque material may be disposed on the pointer, the opaque material defining a plurality of indicia on the pointer.

A method for transferring data blocks from a field device to a server, each data block including data describing an operation of the field device during a block time period is provided. The method includes setting a first and a second pointer delimiting a completed time period; and, until a predetermined transfer period elapses: transferring the data blocks having a block time period that is later than the second pointer to the server in a chronological order; and if all data blocks having a block time period that is later than the second pointer have been transferred to the server, transferring the data blocks having a block time period that is earlier than the first pointer to the server in an anti-chronological order. Data blocks can efficiently and reliably be transferred to the server.

In a light guide pointer, a vertex portion of a light control space is located on a sub-pointer portion side with respect to a center axis of a light entrance shaft, providing appropriate luminance balance between a main pointer portion and the sub-pointer portion. The light control space includes a circular arc portion, thereby broadening diffusion range of light that has passed through the light control space and preventing attenuation of light traveling along inclined portions. A center of the circular arc portion is located on the main pointer portion side with respect to the center axis, allowing strong light that has entered the light control space from the vertex portion to be diffused more. Local focusing and/or attenuation of light can be prevented, while providing appropriate luminance balance between the main pointer portion side and the sub-pointer portion side, thereby reducing luminance unevenness at the light emitting face.
