LIGHTING DEVICE AND FLEXIBLE SUBSTRATE CONNECTING LIGHT EMITTING PORTION THEREOF

The invention provides a lighting device and a flexible substrate connecting a light emitting portion thereof. The lighting device that can prevent the progress of minute cracks generated in a flexible substrate or the occurrence of minute cracks themselves, and the flexible substrate. A flexible substrate, that electrically connect a light emitting portion movable relative to a main body portionof the lighting device, has a soldering portion that is soldered to the light emitting portion at one end, a connection portion that is connected to the light emission control portion at another end,a communication portion that connects the soldering portion and the connection portion, and two xenon wires and two trigger wires that are arranged in the communication portion in a longitudinal direction. In the communication portion, of the four wires, the two xenon wires are arranged between the two trigger wires. 照明装置及连接其发光部的柔性基板。一种能够防止在柔性基板中产生的微小裂纹发展或微小裂纹本身产生的照明装置以及柔性基板。电连接能够相对于照明装置的主体部移动的发光部的柔性基板具有：在一端处焊接到发光部的焊接部；在另一
