Abstract: An LED lamp A1 includes a plurality of LED modules 1 and a substrate 2 on which the LED modules 1 are mounted in a row. A light guide 3 covering the LED modules 1 is provided on the substrate 2. The light guide 3 is held in close contact with each of the LED modules. With this arrangement, a proper amount of light is obtained with the use of a smaller number of LED modules 1 or with less power consumption.

Abstract: A lighting device includes a substrate having a side extending straight in a first direction and a first LED chip supported by the substrate and having a first anode terminal and a first cathode terminal. The lighting device includes a second LED chip and a third LED chip supported by the substrate, being electrically connected to the second cathode terminal, and being overlapped with the first LED chip when viewed in a second direction that is perpendicular to the first direction. The lighting device includes a connecting portion that connects the first cathode terminal and the second anode terminal with each other, at least a portion of the connecting portion angled at an acute angle with respect to the second direction.

Abstract: A lighting device includes a substrate and a planar light source portion including a plurality of LED chips arrayed on the substrate. The planar light source portion faces an illumination space (space to be illuminated) by a predetermined opening area. The plurality of LED chips are arrayed on the substrate such that the mounting density with respect to the opening area is not less than 3/cm2, and accordingly, a planar light source is formed.
Abstract translation: 照明装置包括基板和包括排列在基板上的多个LED芯片的平面光源部。 平面光源部分面向预定开口区域的照明空间（待照明空间）。 多个LED芯片排列在基板上，使得相对于开口面积的安装密度不小于3 / cm 2，因此形成平面光源。
