Description

Light guide LED lighting fixture structure

technical field

Effect, so that the composed lamps can not only effectively overcome multiple light shadows, but also improve the lighting range and make the light more uniform and bright.

Background technique

By the way, lamps have been invented for a long time. With the continuous improvement of life taste and active research and development in the industry, modern lighting has various appearances. Due to the large market demand, based on functional and practical considerations , There have been many related improved structures throughout the history.

However, no matter how the lamps are changed, either bulbs or tubes are used inside, so there are still problems of power consumption and heat generation, which will not only affect the service life of the lamps, but also easily lead to an increase in the ambient temperature, especially at home. Commonly used fluorescent lamps have the disadvantage of oscillating and flickering causing eye damage.

The life of LEDs in the new generation of light-emitting components is at least 10 years longer than the current lighting system, and the power consumption is lower. In addition, LEDs do not contain mercury and are harmless to the environment. In the future, they will replace lamp tubes and become the best lighting source.

However, LED light is unidirectional and is not easy to scatter evenly, so that the illumination angle of the overall lamp cannot be effectively improved. Therefore, in order to overcome this shortcoming, the most common way is to aggregate multiple LEDs with multi-angle distribution to achieve this. In this way, the shape is configured with multiple sides and corners, which is not only difficult to manufacture but also increases the cost, and the effect of light scattering is still limited and not perfect, especially when multiple pieces are used, multiple light and shadows will overlap and stagger. It has become a major fatal injury that cannot really replace traditional lighting in its implementation.

In view of this, the designer previously provided an improved structure of the light guide plate, which was approved to be listed as China Taiwan Patent Announcement No. M306666, which mainly includes: a light guide plate made of high light-transmitting material, and a clear The light-transmitting layer; the back is integrally formed with a reflective layer, and the middle of the reflective layer is inward and can be provided with an arc-shaped convex part during implementation; thereby, it can be combined with a side light source to form an ultra-thin lighting lamp. The projected light is uniform and bright so as to increase the effective lighting range and also solve the shortcoming of multiple light shadows of the known LED lights.

Although its structure has achieved good application results, the reflective layer inside is only in the simplest convex configuration, and the planning of the reflection angle of each part is not perfect. Therefore, the designer is striving for perfection and actively investing in research and improvement. Finally, a new generation of products with better reflection effect and more uniform light emission has been developed.
