  BEST MODE FOR CARRYING OUT THE INVENTION The best embodiment according to the present invention will be specifically described below with reference to the drawings.

  1 to 7 show an embodiment of a signal indicator lamp according to the present invention, and FIG. 1 is a perspective view for explaining the entire signal indicator lamp and its mounting peripheral portion. The signal indicator lamp 10 is attached to the upper end of a round pipe-like column 30 via a column mounting part 20, and the column mounting unit 20 is provided with a sensor S for sensing. The signal indicator lamp 10 is arranged with a light source 2 that is an LED oriented in a plurality of directions around a cylindrical main body 1, and a solar cell device 4 is further attached to the upper end of the cylindrical main body 1. The main body 1, the light source 2, and the solar cell device 4 are covered with a light-transmitting cylindrical cover 51 and a shell-like cover 52, and are protected from rainwater and the like. The cylindrical cover 51 and the shell cover 52 are firmly fused by ultrasonic fusion. The shell cover 52 is made colorless and transparent in order to increase the incident efficiency of sunlight on the solar cell device 4, but the cylindrical cover 51 is made red and transparent, and the light emitted from the light source 2 is received. It is designed to be red light. Further, the cylindrical main body 1 and the cylindrical cover 51 are attached to the column attachment part 20 via the lower attachment part 6.

  FIG. 2 is an explanatory view showing details of the cylindrical main body 1 and attachment of the light emitting substrate to the cylindrical main body 1. The cylindrical main body 1 has a hollow cylindrical shape, and is provided with mounting grooves 11 that open outward at equal angles in the six directions of the outer periphery. The mounting grooves 11 are provided in the vertical direction of the cylindrical main body 1 and are relatively A concave groove 111 provided in the direction and a wiring space 112 provided in the back of the concave groove are provided. Inside the cylindrical main body 1, screw holes 12 are provided in four directions opposite to each other, and substrate insertion grooves 13 are provided in two opposite directions other than the screw holes 12 provided therein. On the other hand, the light-emitting board 3 includes a vertically long circuit board 31 and a plurality of light sources 2 that are LEDs mounted in the up-down direction of the circuit board 31, and the width of the circuit board 31 in the left-right direction is opposite concave grooves 111. It is often made smaller than the spacing between the bottoms of the two. About the board | substrates for light emission control etc. other than the power supply to the light source 2 etc. which cannot be provided in the circuit board 31, if it is provided in the hollow part of the cylindrical main body 1, it will be short wiring, and the board | substrate will not be seen and an external appearance It can be good and is preferred.

  The light emitting board 3 inserted from the lower ends of the left and right ends of the circuit board 31 between the concave grooves 111 is slidable in the vertical direction, and the light emitting board 3 can be easily attached to the cylindrical body 1. It can be easily removed during maintenance. Similarly, a control board 33 for controlling the light emission of the light source 2 is slidably inserted from the lower end into the board insertion groove 13 provided opposite to the inner surface of the cylindrical main body 1. Since the mounting groove 11 is provided with a wiring space 112 at the back, even if wiring, LED electrodes, or the like (not shown) protrude from the back side of the circuit board 31, they pass through the wiring space 112. The possibility of hindering the attachment and removal of the light emitting board 3 can be eliminated, and the control board 33 is provided so as to cross the vicinity of the center of the cylindrical body 1 in the board insertion groove 13. Thus, even if wiring, peripheral devices, etc. (not shown) are provided on the surface of the control board 32, the possibility of hindering attachment and removal is eliminated. By mounting the light emitting substrate 3 by sliding it in each of the mounting grooves 11 provided around the cylindrical main body 1, the light source 2 is provided in six directions radially in a plan view.
