Abstract: A light emitting diode illumination device includes an LED illumination tube having a light transmission plate, an LED element provided in the tube, light reflecting members extending toward a main light irradiation direction symmetrically or asymmetrically with respect to a center line of the LED element, and light intensity and distribution control means for controlling intensity and distribution of a light irradiated from the LED element. The light reflecting member may include a light transmissive member to control the light intensity and distribution. The illumination device may further include light confining means for confining the light emitted from the LED element in a space between the light transmission plate and the light reflecting member and emitting the confined light to the outside of the LED illumination tube through the light transmission plate.

Abstract: Provided is a light-emitting diode-type illumination device which controls, at a high illuminance, the illuminance of directed light emitted by an LED element as a light source. This light-emitting diode-type illumination device 1 comprises a directed illuminance control means which directs the light emitted from a LED element 13 and controls the directed illuminance of the irradiated light, and a light-reflecting member 19 equipped with a convergent reflecting surface 19a positioned on the light-emitting side of the LED element 13. The light-reflecting member 19 is positioned so as to extend in the direction in which light is irradiated, symmetrically or asymmetrically with respect to the centerline of the LED element 13. The directed illuminance control means controls the directed illuminance of light obtained by directing and irradiating light emitted from the LED element 13.

Abstract: An LED lighting device includes a light reflective member. The light reflective member is provided to extend so as to cause light emitted from an LED element to have light directivity and to radiate from an LED lighting tube to the outside of the tube. The reflective member includes a light directivity forming surface and a pseudo LED element forming surface. The light directivity forming surface causes the light emitted from the LED element to have the light directivity and to be directed from the LED lighting tube toward the outside of the tube. The pseudo LED element forming surface reflects a pseudo LED element of the LED element installed on the substrate. The light radiated from the LED element is radiated to the outside of the tube after having been confined in the tube.

Abstract: The present invention provides a straight tube type light emitting diode lamp with which high heat dissipation performance and high illuminance can be obtained. A cover (23) has a translucent cover (31) through which light emitted from an LED element (13) passes, and a first heat sink (33) coupled to a heat sink (15). A second heat sink (17) receives heat via a substrate (12), said heat having been generated from the LED element (13), and transmits the heat to a third heat sink (19). The third heat sink (19) extends toward the translucent cover (31) from one end, which serves as a coupling section coupled with the second heat sink (17), and the other end is coupled to the first heat sink (33). The LED element (13) is positioned on a center line (61) of the translucent cover (31) formed along a cross-section thereof.
