摘要： According to the present invention, a resin molded product provided with engaging projections to be engaged with engaging members, which have been previously formed in side walls of a frame member, and wing members to be in contact with top portions of the side walls of the frame member alternately formed on the side walls thereof is used as a rod lens of the linear light source. Thus, a curvature of the rod lens can be optionally selected and the linear light source is superior also in assembling. In addition, in the case where this rod lens is composed of a lens surface covering a width of opening of the frame member and an almost flat counter surface positioned opposite to this lens surface, a light-scattering effect is brought about in the counter surface of the rod lens by taking a refractive index or a thickness of this rod lens into consideration, whereby a width of illumination can be increased.

摘要： Grooves are formed along the length inside a frame member formed by integrating a lens and reflecting frames. A base plate on which light emitting diodes are arranged in a line is held in the frame member by being inserted in the grooves. The lower part of the frame member is open so that heat is released directly from the base plate, thereby preventing the warp of the base plate and the frame member due to an increase in temperature.

摘要： An LED device comprises first to N-th (N is an integer of 2 or more) LEDs each having one end connected to one another and having different emission colors, and first to N-th transistors each having one end connected to the other ends of the individual LEDs and the other end connected to one another. The first to N-th transistors configure a current mirror circuit. A drive current supplied from outside is distributed to the individual LEDs at a current ratio corresponding to a size ratio of the individual transistors.
