Back projection illuminating device

Abstract

The invention relates to a back projection illuminating device, which comprises a light source (1), a top cover (2), a communicating pipeline (3) and a reflecting mirror surface (4), wherein the two ends of the communicating pipeline (3) are cut through; one end of the communicating pipeline (3) is connected with the edge of the top cover (2); a pipeline port in the end part of the communicating pipeline (3) faces the inner side face of the top cover (2); the light source (1) is externally connected with a power supply through a power wire and the communicating pipeline (3) to supply power; the reflecting mirror surface (4) is formed on the inner surface of the top cover (2); the reflecting surface of the reflecting mirror surface (4) points to the lower side of the inner surface of the top cover (2); the light source (1) is arranged in a pipeline on the end part of the communicating pipeline (3) connected with the edge of the top cover (2); the illuminating direction of the light source (1) points to the inner side face of the top cover (2). According to the reflection principle, irradiation light rays can be softened via the back projection illuminating device; the back projection illuminating device has a very large market application prospect and high economic value.

Description

technical field [0001] The invention relates to a rear projection lighting device. Background technique [0002] Lighting makes life more colorful, and bright lights make people's lives more beautiful. As people's taste in life becomes higher and higher, the requirements for lighting are also increasing. Various lights, all kinds of All kinds of lighting fixtures are the product of people's pursuit of a better life, but from beginning to end, people's constant pursuit is to make efforts in heat dissipation, light intensity, and appearance, but even so, existing lighting devices still have defects , while people consider increasing the brightness of the light, they ignore a problem. The increase of the light intensity will inevitably bring about the problem that the human eye will feel extremely uncomfortable when it is exposed to the light. It will cause damage to human eyes.

[0002] Lighting makes life more colorful, and bright lights make people's lives more beautiful. As people's taste in life becomes higher and higher, the requirements for lighting are also increasing. Various lights, all kinds of All kinds of lighting fixtures are the product of people's pursuit of a better life, but from beginning to end, people's constant pursuit is to make efforts in heat dissipation, light intensity, and appearance, but even so, existing lighting devices still have defects , while people consider increasing the brightness of the light, they ignore a problem. The increase of the light intensity will inevitably bring about the problem that the human eye will feel extremely uncomfortable when it is exposed to the light. It will cause damage to the human eye. Therefore, while continuously increasing the light intensity, the user's experience is also something that the designer needs to consider, and it needs to be placed at the top of the design factor.
