Lamp structure

This creation is about a luminaire structure, especially about a luminaire structure with specific visual effects.

Since Edison invented electric lights, people's lighting fixtures have replaced the way they burn kerosene and candles with silk bulbs. Moreover, with the progress of time and the advancement of technology, the types of lighting fixtures today are very diverse, including fluorescent tubes, power-saving bulbs or light-emitting diode (LED) bulbs, which can be said to have everything.

However, the above existing lighting fixtures are simple in structure and lack of variation, and individual lamps, bulbs or LEDs can only provide a local area of illumination source, and cannot provide large-area illumination indoors or outdoors. Traditionally, the luminaire structure may provide a large area of illumination by connecting a plurality of lamps (or a plurality of bulbs, LEDs) in parallel, but the manner in which the individual tubes are connected in parallel is still not visually and lightly tuned. Take off each mode of light and separate politics.

Therefore, how to make the indoor and outdoor lighting fixture structure be used as a large-area illumination, and can mix the illumination light of a plurality of illumination light sources (such as a bulb, a lamp, an LED), so that the lamp structure is suitable for different sizes, Different luminescence properties or conditions of different uniformity and specific visual effects are the goals of those skilled in the art.

The main purpose of this creation is to provide large-area illumination indoors or outdoors, so that the lighting structure can be used to illuminate multiple illumination sources (such as bulbs, tubes, LEDs), and is suitable for different sizes and different illumination characteristics. Or different uniformity The situation and has a specific visual effect.

For the above and other purposes, the present invention provides a luminaire structure including a light guide plate, at least one light source, and a light cover. The light guide plate includes a light exit surface and at least one light incident surface. The light source is disposed on the light source. The light-emitting surface of the light guide plate is disposed on a light-emitting surface side of the light guide plate. The light cover comprises a plurality of triangular pyramids, and the bases of the plurality of triangular pyramids are adjacent to each other and arranged on one side of the light cover.

For the above and other purposes, the present invention provides another luminaire structure including a diffuser plate, a plurality of light sources and a lamp cover; wherein the diffuser plate includes a light exit surface and a light incident surface, the light source is disposed on the light source On the light-incident side of the diffuser, the lamp cover is disposed on the light-emitting surface side of the diffuser. The lamp cover includes a plurality of triangular pyramids, and the bases of the plurality of triangular pyramids are adjacent to each other and arranged on one side of the light cover.

Thereby, the luminaire structure of the present creation has the following beneficial effects:

1, can be used as indoor and outdoor lighting fixture structure to provide large-area lighting;

2. It can blend the illumination light of multiple light source (such as bulb, tube, LED), so that the structure of the lamp is suitable for different sizes, different illuminating characteristics or different uniformity and has a visual effect of specific atmosphere.

In order to familiarize the person skilled in the art with the purpose, features and effects of the present invention, the present invention will be described in detail by the following specific embodiments and with the accompanying drawings.

In recent years, people have long used the structure of the backlight module on products such as flat-panel TVs, notebook computers, monitors, and touch screens to serve as backlights for these electronic products. In general, the above products are used to display various visual effects such as pictures, images, animations, etc. However, the electronic products themselves do not emit light, because Therefore, the uniform, high-brightness light source emitted by the backlight module is required to make the above-mentioned pictures, images, and animations clearly visible. In general, the backlight module is divided into a side-type backlight module and a direct-type backlight module, which have different manufacturing costs, and each has different applicable occasions and physical and optical characteristics.

Here, the present invention converts the structure of the above backlight module into an indoor and outdoor lighting fixture structure.
