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.

LED illumination device having light reflecting and transmitting member

Provided is a light-emitting diode-type illumination device with which it is possible to irradiate a broad area with light irradiated from an LED light source. The light-emitting diode-type illumination device comprises an illuminance stimulating means for confining light irradiated from the LED light source in a light-confining means, and stimulating the illuminance of the confined light before irradiating said light.
