Problems solved by technology

However, the lighting products with bright and dark surface brightness changes on the market today either have insufficient brightness uniformity in the bright area, or the change from bright to dark is too fast or too fast, or the brightness is uniform in a small area and then gradually fade away. Dimmed, these are not up to the comfortable and beautiful lighting effect

Embodiment Construction

[0018] Embodiments of the present invention will be described below with reference to the drawings.

[0019] figure 1 A cross-sectional view of a lighting device according to an embodiment of the present invention is shown. The light-emitting diode lighting device with gradually changing brightness according to the present invention includes a side wall reflector 1 , a light source part 2 and a light-emitting surface 4 . The side wall reflector 1 is connected to the light source part 2, and the light-emitting surface 4 is divided into a main light-emitting area 42 and an auxiliary light-emitting area 41. The main light-emitting area 42 and the auxiliary light-emitting area 41 are combined together obliquely, and the main light-emitting area 42 is illuminated by the light source part 2 , the auxiliary light emitting area 41 is indirectly illuminated by the reflected light passing through the side wall reflector 1 .

[0020] In this embodiment, the light-emitting surface 4 is ...

Abstract

The invention provides a gradually varied brightness LED (light-emitting diode) illumination device which comprises a side wall reflector, a light source part and a light outlet surface. The side wall reflector is connected to the light source part; the light outlet surface comprises a main light-emitting area and auxiliary light-emitting areas; the main light-emitting area and the auxiliary light-emitting areas are combined together obliquely; the main light-emitting area is illuminated by the light source part; and the auxiliary light-emitting areas are illuminated indirectly by light reflected by the side wall reflector. According to the illumination device, the surface brightness in the larger area, namely the main illumination area, is uniform, and at the same time, a slow transition effect from brightness to darkness is achieved in the auxiliary illumination areas on the two sides.

Description

technical field [0001] The present invention relates to an illuminating device, more specifically, the present invention relates to an LED illuminating device with gradually changing brightness. Background technique [0002] According to a survey and analysis conducted by Energy Star in the United States, lighting fixtures with a slow transition effect in surface brightness from bright to dark can give people a more comfortable feeling, and some consumers are more unique to lighting fixtures with a slow gradient of light-emitting surface brightness. bell. However, the lighting products with bright and dark surface brightness changes on the market today either have insufficient brightness uniformity in the bright area, or the change from bright to dark is too fast or too fast, or the brightness is uniform in a small area and then gradually fade away. Dimmed, these are not up to the comfortable and beautiful lighting effect. [0003] Therefore, there is a need for an illumin...
