The invention provides an image projection device and a vehicle lamp, which can realize miniaturization and light weight while suppressing temperature rise of a digital micromirror device. The image projection device is used for projecting an image by reflecting light from a digital micromirror device (102) provided with a plurality of minute mirrors, and the image projection device is provided with: a mirror mounting substrate (101a) on which the digital micromirror device (102) is mounted; a power source mounting substrate (101b) formed separately from the mirror mounting substrate (101a); a flexible cable (108) that electrically connects the mirror mounting substrate (101a) and the power supply mounting substrate (101b); and a mirror power supply unit (109) for supplying power to the digital micromirror device (102) via a flexible cable (108), wherein the mirror power supply unit (109) is mounted on the power supply mounting substrate (101b).

    本发明提供一种图像投影装置及车辆用灯具,在抑制数字微镜器件的温度上升的同时能够实现小型化及轻量化。一种图像投影装置,由具备多个微小反射镜的数字微镜器件(102)反射光而对图像进行投影,其中,具备:反射镜搭载基板(101a),其供数字微镜器件(102)搭载;电源搭载基板(101b),其与反射镜搭载基板(101a)分体形成;柔性电缆(108),其将反射镜搭载基板(101a)和电源搭载基板(101b)电连接;在电源搭载基板(101b)上搭载有经由柔性电缆(108)向数字微镜器件(102)供给电力的反射镜用电源部(109)。
