A light transforming method and device that includes a lens having one or more specifically shaped surfaces designed to generate an output image by directing the appropriate amount of electromagnetic energy from a pseudo-collimated beam to the required regions of the output image for the purpose of recreating the output image. An LED is collimated to produce the minimum spot size at the projection plane reasonably achievable and the pseudo-collimated light source impinges on the image shaping lens surface(s) such that the light is redistributed in correct proportion and angle to generate the predetermined output image. The image generating surface of the present invention is defined by a multitude of triangular facets that define a free-form surface shape such that when the energy distribution pattern exits the free-form surface the output image closely resembles the required output distribution pattern.

A tubular core assembly for roll of paper or other sheet material has a hollow cylindrical core member formed of paperboard material and an annular end member of plastic material within each opposite end portion of the core member.

Each end member also has at least two radially-projecting lugs at the respective end of the tubular core assembly positioned so as to be rotationally balanced. The core member has at least two lug-receiving notches at each end receiving lugs of the respective end member to rotationally equalize continuous torque and axial chuck pressure from each end member to the core member. Each end member also has an inner annular surface at the end which is continuous and of constant radius around the circumference thereof.

A kind of illuminate device light controls multiple functions natural lamp with the natural wind energy and the solar energy generating electricity. It is at the outside of hollow hexangular base circular holder pipe makes the four-groove vertical revolving tray, inner gear mission, pillow, 100W DC generator, hexangular surface shape big lamp screen, solar energy battery plate, steady flow voltage regulator, charging bomb, light controller, and the energy-saving bulb connected in sequence assemble. The charging bomb inlet wire positive and negative electrode connect with the output positive and negative electrode line of the 100W DC generator and the solar energy battery plate and the charging bomb's output positive and negative electrode line connects with the energy-saving lamp supplying electricity among of them connecting the light controller in series. When there is the wind and the solar the 100W DC generator and the solar energy battery plate supply the electricity for the charging bomb at the same time; when there is no wind and solar the charging bomb supplies the electricity for the energy-saving lamp supplying electricity circuit. Among them it connects the light controller in series and the ray of light is strong so the light controller cuts the energy-saving lamp supplying electricity circuit automatically; at night there is no light so the light controller will turn on the energy-saving lamp supplying electricity circuit automatically.
