Embodiment Construction

[0035] In order to make the above objects, features and advantages of the present invention more comprehensible, specific implementations of the present invention will be described in detail below in conjunction with the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. However, the present invention can be implemented in many other ways different from those described here, and those skilled in the art can make similar improvements without departing from the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0036] refer to figure 1 , figure 2 and Figure 7 , an illumination device provided by an embodiment of the present invention includes an object to be illuminated and a light emitting component 20 . The surface of the object to be illuminated is provided with concavo-convex lines. Th...

Abstract

The invention relates to an illumination device and an elevator car. The illumination device comprises an illuminated body and a light-emitting assembly. Concave-convex lines are arranged on the surface of the illuminated body. The light-emitting assembly can move close to or away from the illuminated body. The light-emitting assembly comprises a light source, light emitted by the light source canirradiate the concave-convex lines, and a light pattern is formed on the surface of the illuminated body. When the light emitted by the light source irradiates the illuminated body, reflected light can be generated, the reflected light passes through the concave-convex lines, a light pattern is formed on the surface of the illuminated body, light pattern illumination is achieved, and discomfort such as dazzling and blurring caused by direct irradiation of light to human eyes is avoided. Compared with a bright spot of the light source, the light pattern is formed on the surface of the illuminated body, so that the lighting effect area is increased, the light utilization rate is effectively improved, the space illuminance is increased, and the purpose of reducing the cost is reduced. In theinstallation process, the light-emitting assembly moves close to or away from the illuminated body, the relative installation position of the light-emitting assembly and the illuminated body is adjusted, adjustment of the light pattern is achieved, and therefore adjustment of the illumination intensity is achieved.

Description

technical field [0001] The invention relates to the technical field of lighting, in particular to a lighting device and an elevator car. Background technique [0002] Lighting devices are widely used in home decoration, public places, elevator cars, etc. Generally, there are two ways of lighting: one is the direct irradiation of lighting fixtures, so that the light emitted by the lighting fixtures directly hits the human eyes, which will cause glare, glare and discomfort, and even cause damage to the human eyes. The other is indirect illumination through a light-transmitting panel. This lighting effect is relatively simple and only meets the lighting function. For traditional lighting methods, it is urgent to propose a lighting structure that can solve the above problems. Contents of the invention [0003] Based on this, it is necessary to provide a lighting device and an elevator car, which can achieve the effect of light pattern lighting, avoid discomfort such as glare...
