Abstract

The invention discloses a hood-shaped light guiding structure and an illumination lamp provided with the hood-shaped light guiding structure. The hood-shaped light guiding structure comprises a hood-shaped light guiding plate, a hood-shaped reflection layer and a hood-shaped diffusion layer, and the section of the hood-shaped light guiding plate, the section of the hood-shaped reflection layer and the section of the hood-shaped diffusion layer are all cambered. An inner hood face of the hood-shaped light guiding plate is tightly covered with a reflection face of the hood-shaped reflection layer. Light guiding lattice points are arranged either on the reflection face of the hood-shaped reflection layer or on the inner hood face of the hood-shaped light guiding plate. An outer hood face of the hood-shaped light guiding plate is tightly covered with the hood-shaped diffusion layer. The illumination lamp provided with the hood-shaped light guiding structure is provided with a support. The hood-shaped light guiding structure is installed on the support. A circle of a light source is arranged at the top end of the hood-shaped light guiding plate. Lights of the light source are emitted into the hood-shaped light guiding plate from the top end of the hood-shaped light guiding plate. Dirt cannot enter the illumination lamp due to the hood-shaped light guiding structure, so that the beauty and illumination of the illumination lamp adopting the hood-shaped light guiding structure are not influenced by dirt entering, the interior of the illumination lamp does not need to be cleaned at all, and shining is more uniform.

Description

Technical field [0001] The invention belongs to the field of optoelectronic materials, and specifically relates to a light guide structure and a product using the light guide structure. Background technique [0002] Prior art ceiling lights, such as figure 1 As shown, it is generally composed of a ceiling bracket A, a light source B, and a lamp shade C. The ceiling bracket A is installed on the ceiling, the light source B is installed on the ceiling bracket A, and the lamp shade C is fixed to the ceiling bracket A and covers the light source B. . This traditional ceiling lamp has the following defects: a cavity D is formed in the lampshade, and dead insects, dust and other dirt are easy to accumulate in this cavity. These dirt E adheres to the inner surface of the lampshade, which not only affects the ceiling lamp The aesthetics will also affect the brightness of the lamp. If you need to remove the lampshade to clean the lamp, it is very time-consuming and laborious. Summary of...
