Lamp structure

The invention relates to a luminaire, in particular to a luminaire structure for illumination.

The technology is changing with each passing day, and the research and development of the luminaire structure is constantly pushing new layers, so that the illuminating diode and the light guide plate have more combinations. The light guide plate can be widely used in various electronic products, such as a screen display, a display panel, and general large and small electronic components such as a keyboard, etc., and the purpose of the light guide plate is to guide the light projected by the light source. The light source can form a uniform light.

In the prior art of the light guide plate, the Light Guide Plate is one of the important components in the backlight module, and its main key function is to be responsible for guiding the light medium, thereby improving the brightness of the panel and Control the brightness evenly. The light guide plate can be divided into an edge light type backlight module or a direct type backlight module according to the direction in which the light source provides light with respect to the light guide plate. As for the choice of the type of light source, due to the current technology and performance improvement of the light-emitting diode, the light-emitting diode is often used as the light source.

Taking the side light source as an example, when the light of the light emitting diode is incident from the side surface of the light guide plate, a total reflection phenomenon is generated inside the light guide plate, so that the light can be irradiated outward from the light guide surface of the light guide plate. In order to enable the light to be uniformly and stably emitted from the light guide plate, the light-emitting surface of the light guide plate and the reflective surface of the light-emitting surface have various micro structures (ie, printed patterns or dots) for destroying the light of the light-emitting diode. The total reflection phenomenon of the light guide plate causes the reflected light to diffuse at various angles, and uses the dense and different diffusion dot pattern design to destroy the total reflection of the light, and guide the light to the light guide plate. The larger the refractive index, the better the light guiding ability. The design of the micro-structure must consider various factors, such as the utilization of light, the angle of reflection of light and the uniformity of light.

In the prior art, the structure of the light guide plate is mostly a flat shape or a wedge type plate, and the general notebook computer adopts a wedge type plate due to the spatial relationship. Liquid crystal display screens are usually dominated by flat panels.
