摘要:
A light guide member capable of reducing an unevenness of luminescent color and further a nonuniformity in luminance when obtaining a white color by a color mixture using a plurality of light sources, a flat light source device and a display device are provided.A protrusion 4 of a cylindrical shape is formed upward a plurality color of LED light sources 5R, 5G, 5B, e.g., RGB color at a backside face of a light guide member 1, and a conical depression 3 is disposed at the position directly over the protrusion. Lights of each color from LED light sources 5R, 5G, 5B are mixed at the protrusion 4, thereafter reflect at the depression 3 and propagates in a horizontal direction at a light guide portion 2.

A light guide member capable of reducing an unevenness of luminescent color and further a nonuniformity in luminance when obtaining a white color by a color mixture using a plurality of light sources. Also disclosed are a flat light source device and a display device. A protrusion (4) of a cylindrical shape is formed upward a plurality color of LED light sources 5R, 5G, 5B, e.g., RGB color at a backside face of a light guide member (1), and a conical depression (3) is disposed at the position directly over the protrusion. Lights of each color from LED light sources 5R, 5G, 5B are mixed at the protrusion (4), thereafter reflect at the depression (3) and propagate in a horizontal direction at a light guide portion (2).

A light emitting module (40) includes: eight LEDs emitting red, green and blue light; electric conductor part (60) electrically connected to the LEDs and constitute power feeding routes for the LEDs; a heat conductor part (50) provided so as to be electrically insulated from the electric conductor parts (60) and constitute a heat dissipating route for heat produced by the LEDs; and a lens (70) which seals the LEDs while including respective parts of the electric conductor parts (60) and the heat conductor part (50). Bending process is applied to each of the electrodes, such as a red positive lead electrode portion (61a), of the electric conductor part (60) which are exposed from the lens (70) and a heat dissipating portion (52) etc. in the heat conductor part (50) which are exposed from the lens (70). Accordingly, temperature change in the light emitting elements and accompanying light intensity change are suppressed, and at the same time, thinning of the light emitting device including the light emitting elements is achieved.

A light emitting module (12) is provided with a circuit board (20), a plurality of LED chips (21) mounted on a surface of the circuit board (20), and a plurality of lenses (30) covering the LED chips (21). The circuit board (20) is provided with a plurality of portions defining gate holes (27), which penetrate the circuit board from a front surface to a rear surface, and a runner (26), which is formed to pass on the portions defining the gate holes (27) on the rear surface side of the circuit board (20). The plurality of lenses (30) are formed on the front surface of the circuit board (20) by injection-molding a resin for the lens through the runner (26) and the portions defining the gate holes (27). Connecting sections (31) each integrated with corresponding one of the lenses (30) are formed in the portions defining the gate holes (27), and a supporting section (32) integrated with the connecting sections (31) is formed in the runner (26). At this time, a height of the supporting section (32) formed in the runner (26) is set at a height of the rear surface of the circuit board (20) or lower. Thus, mechanical stability of a cover member and the like arranged corresponding to a solid-state light emitting element is improved.
