Example Embodiment

[0025] Embodiments of the present invention will be described below with reference to the drawings. The present invention is not limited to the following embodiments, and various modifications and application examples of the technical concept of the present invention are also included in the scope of the present invention.

[0026] like figure 1 As shown, an elevator car 1 has a floor 2 , side panels 3 erected on the floor 2 , elevator doors 4 as entrances and exits, a ceiling 5 forming the top, and lighting devices 6 arranged on the ceiling 5 . The illuminating device 6 includes a milky-white light-transmitting plate 7 made of acrylic resin, and in this embodiment, the light-transmitting plate 7 is divided into four light-transmitting plates. The light-transmitting plate 7 is configured such that each outer peripheral edge thereof is supported by a cross-shaped center seam member 10 so as not to fall down.

[0027] like figure 2 and image 3 As shown, the lighting device...

Abstract

The invention provides a lighting device for an elevator car, dark areas generated along a joint component supporting a light-transmitting plate due to the irradiation of light from an LED lamp can be reduced, and the LED lamp can be replaced in the elevator car conveniently. Along the joint component, a ceiling arranged over the joint component is provided with a light-shielding body for shielding light which forms a projection shadow of the joint component in the irradiation direction of the light of the LED lamp, and a gap through which the light-transmitting plate can pass is arranged between the light-shielding body and the joint component. Due to the fact that the light-shielding body is employed to shield the light which is of the LED lamp and forms the projection shadow of the joint component towards the irradiation direction of the joint component, projection shadows of the joint component in the irradiation direction of the LED lamp are not liable to generate, due to the fact that dark areas generated along the joint component do not generate on the light-transmitting plate, and therefore the appearance of the light-transmitting plate can be improved. In addition, due to the fact the light-transmitting plate can pass through the gap between the light-shielding body and the joint component, and the LED lamp can be replaced in the elevator car.

Description

technical field [0001] The invention relates to a lighting device for an elevator car, in particular to a lighting device for an elevator car that uses a light source composed of LED lamps to illuminate the inside of the elevator car. Background technique [0002] In the interior of the elevator car, in order to facilitate the operation of the operation buttons and take safety measures, the interior of the elevator car is illuminated by a lighting device. In the prior art, light bulbs and fluorescent lamps are used as the lighting device, so the lighting device has a large volume and large power consumption, and maintenance and management such as frequent replacement of the light bulb and fluorescent lamp are required, and the glass of the light bulb and fluorescent lamp is easily damaged. hazards etc. [0003] Therefore, in recent years, improvements have been made from the perspectives of miniaturization, reduction of power consumption, and convenience of maintenance and ...
