Light in the horizontal angle of 0 ° is irradiated toward a range of 60 to 90 ° vertical angle (more preferably 70 to 80 ° vertical angle), and the luminous intensity of the irradiation range is higher than that of other ranges. Is also expensive. Further, the light in the horizontal angle 0 ° direction, the light in the horizontal angle 45 ° direction, and the light in the horizontal angle 90 ° direction are installed in the vertical angle 0 ° direction, and further on the minus side of the vertical angle 0 ° direction, that is, the lighting fixture 10. The wall side is also illuminated.

The light distribution characteristics of the emergency light source 13 are that the emergency light source portion 13 is arranged on the inclined surface portion 26 of the instrument main body 11 and the optical axis of the emergency light source 13 is directed diagonally downward. It is obtained by the light source unit 13 including the lens 62.

Further, as shown in FIG. 3, the terminal block 14 is arranged on the back surface portion 28 of the main body chassis 20, and a power supply line for supplying an external power source is connected to the terminal block 14.

Further, the battery 15 is a rechargeable and dischargeable storage battery, and is arranged on the back surface portion 28 of the main body chassis 20.

Further, the power supply unit 16 inputs an external power source such as an AC power supply supplied through the terminal block 14, converts it into a lighting power source such as a DC power supply, supplies it to the light emitting module 45 of the main light source 12, and lights the light emitting element 51. Let me.

Further, the lighting unit 17 inputs an external power supply supplied through the terminal block 14, and is also connected to the battery 15. The lighting unit 17 has a power failure detection circuit that detects a power failure of an external power supply, a charging circuit that charges the battery 15 when an external power supply is supplied, and an emergency light source 13 that supplies lighting power to the emergency light source 13 by the power supply of the battery 15 when the external power supply fails. It is equipped with a lighting circuit for lighting.

Further, the lighting unit 17 includes an inspection unit 70 for instructing an emergency lighting inspection including an emergency light source 13 and a battery 15, and an inspection circuit for executing an inspection mode according to the inspection instruction.

The inspection unit 70 is arranged to face the inspection window 42 of the lower surface portion 27 of the instrument main body 11, and is a receiving unit that receives a wireless signal such as an infrared signal transmitted from a terminal such as an inspection remote controller, and an inspection result. It is equipped with a transmitter that sends to the terminal, an inspection switch for manually instructing inspection, and a monitor lamp that displays inspection results.

Next, FIGS. 8 and 9 show the installation state of the lighting fixture 10. The luminaire 10 is installed on the wall surface 75 of the landing 74 of the indoor stairs 73 so that the width direction of the luminaire 10 is horizontal.

Then, in a normal time when an external power source is supplied to the luminaire 10, the power supply unit 16 converts the external power source into a predetermined lighting power source and supplies the external power source to the main light source 12. Therefore, the main light source 12 is turned on to illuminate the stairs 73 and the landing 74.

The light from the light emitting element 51 of the main light source 12 to be lit is transmitted through the diffusion cover 48, diffused in a wide range by the prism 56 of the diffusion cover 48, and further transmitted through the light transmissive cover 47 and diffused in a wide range. Is irradiated to.

Of the light transmitted through the translucent cover 47, some of the light that goes downward is radiated to the lower surface side of the wall surface 75 and the floor surface of the landing 74 through the front side of the inclined surface portion 26 of the instrument body 11, so that the landing 74 It has the effect of brightening the vicinity. If there is no inclined surface portion 26 on the lower front side of the instrument main body 11 and the flat surface is continuous with the front portion 25, light is blocked by the lower front side of the instrument main body 11 and the lower surface side of the wall surface 75 or the landing. The floor of 74 is not illuminated and the area around the landing 74 becomes dark.

Further, in the normal state, since the lighting unit 17 detects the supply of the external power source, the battery 15 is charged by the external power source, but the emergency light source 13 is turned off.

Then, in the event of a power failure in which the supply of the external power supply to the lighting fixture 10 is stopped, the lighting unit 17 detects the power failure of the external power supply, converts the power supply of the battery 15 into a predetermined lighting power supply, and supplies the power to the emergency light source 13. Therefore, in the event of a power failure, the main light source 12 is turned off, but the emergency light source 13 is turned on, illuminating the stairs 73 and the landing 74.

Since the emergency light source 13 is provided on the inclined surface portion 26 of the instrument main body 11, the optical axis of the emergency light source 13 is directed diagonally downward. Therefore, even if the lighting fixture 10 is installed on the upper side of the wall surface 75 of the landing 74, it is possible to illuminate an appropriate range including the stairs 73 and the landing 74. If there is no inclined surface portion 26 on the lower front side of the instrument body 11 and the plane is continuous with the front surface portion 25, the light from the emergency light source 13 installed on the plane is mainly directed in the horizontal direction. The area around the landing 74 and the stairs 73 on the lower floor from this landing 74 to the lower floor become dark.

Moreover, since the emergency light source 13 controls the light distribution from the light emitting element 65 by the lens 62, the light distribution is controlled so that the light is projected toward the stairs 73 side away from the installation location of the lighting fixture 10. By doing so, the stairs 73 can be brightened.

Further, since the emergency light sources 13 are arranged at two locations on both ends of the instrument main body 11, the stairs 73 side connecting the landing 74 upper floor and the stairs 73 side connecting the landing 74 and the lower floor can be used. Each can be illuminated appropriately.

Moreover, since the emergency light source 13 is arranged in the widthwise region of the main light source 12, the distance between the two emergency light sources 13 is not too wide, and the range illuminated by the two emergency light sources 13 respectively. It is possible to prevent darkening in the middle of the area and illuminate an appropriate range. Further, the size of the lighting fixture 10 in the width direction can be reduced, and other devices such as motion sensors can be arranged at both ends of the lighting fixture 10 in the width direction.

A motion sensor is installed in the lighting fixture 10, and the main light source 12 is turned off when the motion sensor does not detect the human body, and the main light source 12 is turned on when the motion sensor detects the human body. The lighting and extinguishing of the main light source 12 may be automatically controlled.

Further, with respect to the lighting fixture 10, it is regularly inspected whether the emergency light source 13 is lit normally. When inspecting the luminaire 10, the terminal is operated below the luminaire 10 to be inspected by the operator, and an inspection signal is transmitted to the inspection unit 70 of the luminaire 10. When the lighting unit 17 receives an inspection signal from the terminal to the inspection unit 70, the lighting unit 17 enters the inspection mode, turns on the emergency light source 13 with the power supply of the battery 15, and determines the life of the battery 15. The monitor lamp of the inspection unit 70 displays the inspection operation and the inspection result. After the inspection is completed, the inspection unit 70 sends a signal of the inspection result to the terminal. Then, the operator visually confirms the lighting state of the emergency light source 13 and the monitor lamp, confirms the inspection result received by the terminal, and grasps the state of the lighting fixture 10.

Since the inspection unit 70 is provided on the lower surface portion 27 provided from the lower end of the inclined surface portion 26 of the instrument body 11 toward the back side of the instrument body 11, the signal with the terminal is transmitted only in the lower region of the lighting device 10. It is possible to send and receive. As a result, since the lighting fixture 10 is installed at each landing 74 on each floor of the stairs 73, the lighting fixture 10 other than the lighting fixture 10 to be inspected receives the inspection signal from the terminal and malfunctions. Can be prevented.

The emergency light source 13 may be provided at one location in the center of the inclined surface portion 26 of the instrument main body 11 in the width direction, or may emit light continuously along the width direction of the inclined surface portion 26 of the instrument main body 11. It may have a surface.

Although some embodiments of the present invention have been described, these embodiments are presented as examples and are not intended to limit the scope of the invention. These novel embodiments can be implemented in various other embodiments, and various omissions, replacements, and changes can be made without departing from the gist of the invention.
