Lighting device for elevator car

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 ...

AI Technical Summary

Problems solved by technology

Therefore, when the light-transmitting panel is viewed from below, there is a problem that a dark area is formed along the joint member, which affects the appearance.

[0012] In addition, when replacing the LED lamp, if it is replaced from above the ceiling of the elevator car, the efficiency of the replacement work is low, and it is required to adopt a structure that replaces it from the inside of the elevator car.
