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] Hereinafter, embodiments of the present invention will be described 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 gradual 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 unit 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 obliquely, and the main light emitting area 42 is illuminated by the light source 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 formed by splicing the mai...

Abstract

The invention provides a light-emitting diode lighting device with gradually changing brightness, which includes a side wall reflector, a light source part, and a light-emitting surface. The side wall reflector is connected to the light source part, the light-emitting surface includes a main light-emitting area and an auxiliary light-emitting area, the main light-emitting area and the auxiliary light-emitting area are combined obliquely, and the main light-emitting area is illuminated by the light source part , the auxiliary light-emitting area is indirectly illuminated by the reflected light passing through the side wall reflector. The illumination device of the present invention has a uniform surface brightness in a large area, that is, the main lighting area, and at the same time realizes a slow transition effect of brightness from bright to dark in the auxiliary lighting areas on both sides.

Description

Technical field [0001] The present invention relates to a lighting device, more specifically, the present invention relates to a light-emitting diode lighting device with gradual brightness. Background technique [0002] According to a survey and analysis by Energy Star of the United States, lighting fixtures with a slow transition effect of surface brightness from light to dark can give people a sense of comfort. Some consumers are also unique in lighting fixtures with a slow gradual change of light-emitting surface brightness. bell. However, today’s lighting products on the market with brightness changes in surface brightness either have insufficient brightness uniformity in the bright area, or the change from bright to dark is too rapid, or only in a small area after the brightness is uniform. Dimming, these will not achieve comfortable and beautiful lighting effects. [0003] Therefore, there is a need for a lighting device that can achieve a slow transition effect from light...
