    摘要: PURPOSE:To provide a compact LED display device with assembled LEDs. CONSTITUTION:A figure is the side view of a display device 1 with LEDs and the display plane of the device is constituted of a 16X16 matrix in which pixels 40 whose one dot is made up with 3X3 of LEDs are arranged, 16 sheets of LED driving printed boards 5 are arranged in the direction perpendicular to an LED substrate 3 and they are connected with connecters 4, 4'. Moreover, each LED driving printed board 5 is fixed to a control substrate 7 with machine screws. The device can efficiently be manufactured and at a low cost because the LED substrate 3 can be automatically soldered with a conventional device. Further, after a lot of LED driving printed boards are produced independently and 16 sheets of the boards are made to be a set, a module is completed by engaging in the boards with the LED substrate 3. Since the device is constituted so that an LED display part and driving circuits are made separatable the device has also a merit capable of coping with exchanging and changing of LEDs.

    摘要: PURPOSE:To facilitate the change of assembling work by composing a socket to be attached/detached in a circumferential direction for separating work processes properly, and improving the design of a multi-stage signal display lamp by lowering height per light source unit. CONSTITUTION:A chassis 51 on which a socket A having a diagonally installed bulb 1 is inserted and supported to be freely attached/detached is set as one light source unit, and plural stages of the light source units are laminated to compose a signal display lamp. The plural stages of the light source units are fixed through spacers 54, and they are enclosed by a glove 6 having transparency. The bulb 1 in each stage is lighted by a signal input, and signal light colored by the glove 6 is radiated around.
