摘要： A light projecting device comprises a flat light guide plate and a light source that introduces light into the light guide plate from a side peripheral surface thereof. A plurality of concave parts are formed on one plate surface of the light guide plate, and the light entering the light guide plate reflects off the concave parts while spreading out, and the light is emitted outside from the other plate surface of the light guide plate. Each concave part is formed by a smooth concave curved surface. A tangential angle that is an angle between a tangential line at an opening edge of the concave part and the plate surface is set to be ≥50° and ≤85° in a cross-sectional shape of the concave part cut by a plane that is both perpendicular to the plate surface and passing through the center of the concave part.

摘要： An OLED driving device includes an overdrive controller (ODC) which executes an overdrive of applying to an OLED an electric current larger than a rated electric current for the OLED for a predetermined period (period for the overdrive) to cause the OLED to emit brighter light for the predetermined period than at the rated electric current for the OLED for light emitting. The controller (ODC) executes a PWM control to the electric current flowing to the OLED for the predetermined period, and sets a PWM signal in the predetermined period so that at least one pulse of a pulse before the OLED starts the light emitting and a pulse at a just time when the OLED starts the light emitting has a width larger than a width of a pulse after the OLED starts the light emitting.

摘要： A line light irradiation device includes a plurality of light source units on which a plurality of light source mounting substrates are juxtaposed on a base in a row, and the plurality of light source units are juxtaposed in a row. The plurality of light source mounting substrates are positioned and fixed to the base at predetermined intervals. Thus, if a light source in a certain light source unit becomes defective, this light source unit can be removed so as to exchange only the light source mounting substrate on which the defective light source is mounted. Therefore, the normal light sources can be left as they are as much as possible, and waste of the light sources can be reduced. Further, the light source mounting substrates are positioned and fixed at predetermined intervals, and thus dimensional errors do not accumulate in the light source mounting substrates at the juxtaposition ends.
摘要翻译： 线光照射装置包括多个光源单元，多个光源安装基板并列在一排的基部上，并且多个光源单元并排并排。 多个光源安装基板以预定间隔定位并固定到基座。 因此，如果某个光源单元中的光源变得有缺陷，则可以去除该光源单元，以仅更换安装有缺陷光源的光源安装基板。 因此，可以尽可能地保持正常的光源，并且可以减少光源的浪费。 此外，光源安装基板以预定间隔定位和固定，因此尺寸误差不会并列在并置端的光源安装基板中。
