The illuminance detector 14 is mounted on the first circuit board 63.

  The lighting device 16 has a function of lighting the LED element 51 with the commercial AC power supply according to the external illuminance detected by the illuminance detection unit 14 in a state where the commercial AC power is supplied from the plug 15. The LED element 52 is turned on by the power source of the battery 24 stored in the battery storage unit 25 in a state where commercial AC power is not supplied.

  The panel 17 includes a panel body 67 that integrally covers the entire front surface of the cover 21 of the housing 12. The panel body 67 is formed in a flat plate shape having the same shape as the front surface of the cover 21 of the housing 12, and both the front surface and the back surface are formed in a flat shape. In the upper area of the panel body 67, an opaque part (hiding part) 68 having translucency is formed in an area corresponding to the area of the front plate part 26 of the cover 21, and the lower area of the panel body 67 is irradiated with the cover 21. A transparent portion 69 having translucency is formed in a region corresponding to the region of the opening 29. The opaque portion 68 covers the mounting hole 27 and the illuminance detection opening 28 of the cover 21. The opaque part 68 is a translucent part that allows light to pass through although it is not transparent, and the illumination detection opening 28 may be slightly visible even if it is not visible at all when viewed from the front of the panel 17, compared to transparent Therefore, it is sufficient that the visibility of the illuminance detection opening 28 is low.

  In the present embodiment, the panel body 67 is integrally formed of a transparent material such as an acrylic resin, and a light-transmitting paint is applied to the back surface of the panel body 67 corresponding to the formation area of the opaque portion 68, or the transparent body is transparent. An opaque portion 68 is formed by printing a light ink, applying a film, or applying a diffusion treatment to form fine irregularities on the surface, and a transparent portion 69 is formed in a region other than the opaque portion 68. Is formed. In addition, the opaque part 68 and the transparent part 69 can also be formed in the panel main body 67 by forming the panel main body 67 by two-color molding of an opaque material having translucency and a transparent material.

  The panel 17 is attached to the front plate portion 26 of the cover 21 by being adhered with a double-sided adhesive tape or an adhesive. A plurality of claws may protrude from the back surface of the panel 17, and these claws may be locked to the cover 21 for attachment.

  Next, when the safety light 11 configured in this way is used, the plug 15 is rotated so as to protrude from the back surface of the base 22, and the plug 15 is inserted into a wall outlet. As a result, commercial AC power is supplied to the lighting device 16 through the plug 15.

  When the switch 38 is in the ON state, the illuminance detection unit 14 detects the external illuminance, and if it is above a predetermined brightness, the LED element 51 is turned off, and if it is below the predetermined brightness, the commercial AC power supply The LED element 51 is turned on and the night light function is activated.

  At this time, the illuminance detection unit 14 detects the external illuminance from the light collected through the illuminance detection opening 28 of the cover 21. Although the illuminance detection opening 28 is covered with the opaque portion 68 of the panel 17, since the opaque portion 68 has translucency, the light around the safety light 11 passes through the opaque portion 68 and illuminates from the illuminance detection opening 28. The detection unit 14 is reached. Since a part of the light transmitted through the opaque part 68 is shielded and only the remaining part is detected by the illuminance detection unit 14, the lighting device 16 uses the threshold value when judging the external illuminance from the detection value of the illuminance detection unit 14. By appropriately setting, the external illuminance can be accurately determined.

  When the switch 38 is in the off state, the extinguished state is maintained regardless of the external illuminance.

  Further, at the time of a power failure, the lighting device 16 detects the power failure and turns on the LED element 52 by the power source of the battery 24.

  Further, the security light 11 can be carried by pulling out the plug 15 of the security light 11 from the outlet. When commercial AC power is being supplied when the plug 15 of the security light 11 is pulled out from the outlet, the LED element 52 is turned on by the power source of the battery 24 in the same way as at the time of a power failure. In this case, the lighting of the LED element 52 by the power source of the battery 24 is maintained.

  In the state where the plug 15 of the security light 11 is pulled out from the outlet and carried, the LED element 52 is turned off by operating the off button 40 while the LED element 52 is lit, and the on button 39 when the LED element 52 is turned off. LED element 52 is lit by operating.

  In the state where the plug 15 is inserted into the wall socket, the LED element 51 or the LED element 52 is turned on, so that most of the light generated by the LED element 51 or the LED element 52 is reflected by the reflecting portion 30. The light is irradiated onto the surface 31 and is reflected forward by the reflecting surface 31 of the reflecting portion 30. The reflected light reflected by the reflecting surface 31 of the reflecting part 30 and the direct light from the LED element 51 or the LED element 52 are transmitted through the transparent part 69 of the panel 17 and irradiated to the floor surface near the outlet, and the reflecting part 30 Since the reflecting surface 31 is curved in the left-right direction, the reflected light is spread and irradiated in the left-right direction. As a result, even if the surroundings are dark, the feet are illuminated.

  Since the LED elements 51 and 52 are disposed downward in the casing 12 so as to face the window 33, direct light from the LED elements 51 and 52 is irradiated to the eyes of a person on the floor surface. The glare can be prevented.

  Then, according to the security light 11 of the present embodiment, the transparent portion 69 and the opaque portion 68 having translucency are formed on the panel body 67 of the panel 17 that covers the front surface of the casing 12, and the casing is formed by the transparent portion 69. 12 covers the illumination opening 29 of the housing 12 and covers the illuminance detection opening 28 of the housing 12 with the opaque portion 68, so that the panel 17 can have a sense of unity and the mounting hole 27 and the illumination detection opening 28 on the front surface of the housing 12 can be provided. Etc. can be concealed and the appearance can be improved.

  Moreover, since the opaque part 68 has translucency, the illuminance detection unit 14 can detect the external illuminance around the safety light 11 through the opaque part 68 and the illuminance detection opening 28.

  In addition, the panel body 67 is integrally formed of a transparent material, and the opaque portion 68 having translucency is formed on the back surface of the panel body 67 corresponding to the formation region of the opaque portion 68, whereby the panel having the opaque portion 68 is formed. 17 can be manufactured easily.

  Further, since the number of parts can be reduced as compared with the case where a panel for covering the illuminance detection opening 28 is individually prepared, it is advantageous in terms of cost, parts management, and assembling ability.

  The light source of the light source unit 13 is not limited to the LED elements 51 and 52 but may be an EL element or an incandescent lamp.

  Although several embodiments of the present invention have been described, these embodiments are presented by way of example and are not intended to limit the scope of the invention. These novel embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the scope of the invention.
