Description

  The present invention relates to an illumination device that illuminates an elevator cab.

  4 and 5 show the configuration of the elevator cab 1. The cab 1 includes a floor 2, a side plate 3 that surrounds the floor 2, and a side plate 3. The ceiling part 4 installed in the upper end part is provided.

  An illumination box 5 is attached to the lower surface of the ceiling 4, and the illumination box 5 has a large opening 6 on the lower surface, and an illumination plate 7 made of light-transmitting synthetic resin is provided in the opening 6. It has been.

  A plurality of straight tube fluorescent lamps 10 are attached to the lower surface of the ceiling portion 4 as light sources for illuminating the illumination plate 7 so as to be evenly arranged in two rows through sockets 11, respectively. These fluorescent lamps 10 illuminate the illuminating plate 7 and the light diffuses into the car room 1 to illuminate the car room 1.

  An entrance / exit 15 is formed in the front of the car room 1, and doors 16 a and 16 b for opening / closing the entrance / exit 15 are provided at the entrance / exit 15. Reference numeral 17 denotes a curtain plate provided on the upper side of the entrance 15 and reference numeral 18 denotes a baseboard provided on the lower side of the side plate portion 3.

  By the way, the design in the cab 1 largely depends on the lighting effect inside the cab 1, and it is important to uniformly illuminate the lighting plate 7 in that respect.

  Conventionally, a plurality of fluorescent lamps 10 are evenly arranged in two rows. However, light hardly reaches both ends of each fluorescent lamp 10, that is, the peripheral part of the socket 11. It becomes dim compared to other parts. That is, a locally dark portion is generated with respect to the entire ceiling portion 4, and as a result, light unevenness in which the brightness of the light reflected on the entire illumination plate 7 is sparse is generated, and the design for lighting of the cab 1 is performed. There is a problem that decreases.

  If the number of fluorescent lamps 10 is increased and a large number of fluorescent lamps 10 are mounted on the lower surface side of the ceiling portion 4 so as to be densely packed, light unevenness can be suppressed. The power consumption increases, leading to an increase in cost.

  The present invention has been made paying attention to such points, and the object of the present invention is to make the brightness of the ceiling portion uniform without causing an increase in cost, to eliminate unevenness of light, and to design a lighting system for a cab. An object of the present invention is to provide an elevator illuminating device capable of improving the performance.

  The invention according to claim 1 is arranged in the elevator car room and the ceiling part of the car room so as to be alternately arranged in a row and arranged in a matrix direction, and each extends along the column direction. A plurality of light sources that are long in one direction and arranged alternately in a dust-like manner are arranged in each blank portion where the light source that is generated in the ceiling portion of the cab is not arranged, and arranged in the side portion of the blank portion A plurality of reflecting members capable of reflecting light emitted from the side portion of the light source toward the end portion of the light source.

  The invention of claim 2 is characterized in that the light source is a straight tube type cold cathode fluorescent lamp.

  According to the present invention, it is possible to make the brightness of the ceiling portion uniform to eliminate light unevenness without increasing the cost, and to improve the design of the lighting of the cab.

  Hereinafter, an embodiment of the present invention will be described with reference to FIG. 1 and FIG. In addition, the same code | symbol is attached | subjected to the part corresponding to the conventional structure, and the overlapping description is abbreviate | omitted.

  In the present invention, as shown in FIG. 2, a plurality of light sources 20 are arranged on the lower surface of the ceiling portion 4 of the cab 1 so as to be alternately arranged in a row and vertically and horizontally in the row direction and the column direction. Has been. Each light source 20 is a straight tube fluorescent lamp that is long in the column direction.

  In the first row, the third row, and the fifth row in the column direction on the lower surface of the ceiling portion 4, there is a blank portion A in which the light source 20 is not disposed between the ends of the light sources 20 arranged in the column direction. As a result, in the second and fourth rows, blank portions B where the light source 20 is not arranged are formed on both end sides of the light source 20 extending in the column direction.

  Each blank portion A and each blank portion B are provided with reflecting members 21a and 21b, respectively. As shown in FIG. 1, the reflecting members 21 a and 21 b have a substantially inverted triangular cross section, and are attached to the lower surface of the ceiling portion 4 by screws or the like along each row of the ceiling portion 4. The surfaces of the reflecting members 21a and 21b are white or silver in order to increase the light reflectance.

  The reflecting members 21a in the first row, the third row, and the fifth row have their side portions opposed to the intermediate portions of the side portions of the light sources 20 arranged in the second row and the fourth row, respectively. The reflecting members 21b in the rows and the fourth rows are in a state in which the side portions thereof are opposed to the side portions in the substantially half of the longitudinal direction of the light sources 20 in the first row, the third row, and the fifth row. Yes.

  In such a configuration, the light emitted from each light source 20 is emitted downward and laterally. The light emitted from the light source 20 to the side is reflected by the reflecting members 21a and 21b disposed adjacent to the side of the light source 20, and the light by the reflection is around the socket 11 at the end of the light source 20. The department is illuminated.

  The periphery of the socket 11 at the end of each light source 20 tends to be dark, but the periphery of the socket 11 is brightly illuminated by the light reflected by the reflecting members 21a and 21b. The darkened portion is almost eliminated, and the entire ceiling portion 4 has a substantially uniform brightness. Therefore, light unevenness hardly occurs in the illumination plate 7, and the design for illumination in the cab 1 is improved.

  And even if it is a case where the number of the light sources 20 does not need to be increased and the size of the cab 1 is changed, it is only necessary to change the lengths of the reflecting members 21a and 21b. Absent.

  By the way, as the light source 20, in addition to the case of using a normal fluorescent lamp (hot cathode tube), a cold cathode fluorescent lamp can be used. The cold cathode fluorescent lamp has a translucent discharge vessel having a diameter of about 1 to 6 mm, a pair of cold cathodes sealed at both ends of the discharge vessel, a phosphor applied to the inner surface of the discharge vessel, A discharge medium enclosed in a discharge vessel, and the cathode emits light without being heated. Therefore, the lifetime is not affected by the number of times of turning on and off, and the lifetime is simply due to the elements caused by the emission time. It has the characteristic of being determined. Another feature of this cold cathode fluorescent lamp is that it is turned on immediately when a voltage is applied and there is no time delay until light emission.

  Therefore, if such a cold cathode fluorescent lamp is used as the light source 20, since the tube diameter of the cold cathode fluorescent lamp is small, the thickness of the illumination box 5 can be configured to be thin, so that the height in the cab 1 is increased. The space can be increased and the space in the cab 1 can be used effectively.

  Furthermore, the cold cathode fluorescent lamp usually has a much longer life than a general fluorescent lamp, so that the replacement period can be greatly extended and maintenance is facilitated. In addition, the cold cathode fluorescent lamp does not have an irregular blinking operation at the time of lighting as in a general fluorescent lamp, and can be turned on immediately, so that the interior of the cab 1 can be illuminated without a sense of incongruity from the moment of lighting. Can do.

  Moreover, as the light source 20 attached to the ceiling part 4, it is also possible to use LED (light emitting diode) and organic EL (electroluminescence) instead of the cold cathode fluorescent lamp. In this case, for example, a plurality of LEDs or organic EL elements can be assembled to a holder having a shape that is long in an appropriate direction as a unit of one light source 20, and the light source 20 can be attached to the plurality of ceiling portions 4. It is.

  The holder may be a case where only an LED is disposed, a case where only an organic EL is disposed, or a case where an appropriate number of LEDs and organic EL are combined. Also good.

  Needless to say, a conventional drive control device is used as a means for causing the LED or organic EL to emit light.
