Optical structure of light guiding confluence

The present invention is an optical structure for guiding light, in particular, a light collecting fluid that converges, converges, and emits light at the end of a light guiding body.

According to the light guide bar, it has been widely used in various types of lamps. The light guiding principle is similar to the optical transmission of total reflection of the fiber, so that the light can be uniformly filled in the light guiding strip, and the reflective layer is disposed on one side of the light guiding strip. Therefore, the light-emitting surface of the light guide strip can be uniformly lighted out, thereby improving the overall visual beauty of the light fixture; therefore, in recent years, many manufacturers have widely used light guide strips for the vehicle lights to improve the vehicle recognition and aesthetics.

However, the conventional light guide strip has a structure and an optical path as shown in FIG. 1 . The light guide strip includes: a light guide body 10 which is made of a light guiding medium, and the light guide body 10 The light guide body 10 has a light incident surface 101, and the light guide body 10 is a light exit surface 102 on a side edge of the vertical light incident surface 101; and a light source 20 is disposed on the light guide body 10; The light incident surface 101 of the light guide body 10; by which, part of the light projected by the light source 20 will be directly emitted by the light exit surface 102, and the other part of the light is totally reflected by the light exit surface 102 until the incident angle thereof can be emitted. The face 102 emits light, and then the light is filled in the light guide body 10 to uniformly emit light, and the light is transmitted toward the end of the light incident surface 101.

However, as shown in FIG. 1, the conventional light guide strip still has a part of the light L, which is directly projected by the light source 20, or is totally reflected by the light exit surface 102 to the end of the light guide body 10, and is emitted. In general, the end of the light guide body 10 is not a viewing angle to be viewed, so that the light L emitted from the end of the light guide body 10 is lost, thereby causing energy loss and reducing luminous efficiency.

Furthermore, the conventional light guide strips are mostly arranged side by side, so the light source 20 will also be arranged side by side, and if the light source 20 is an LED (Light-Emitting Diode), due to the power conversion efficiency of the LED, only 15 to 20% is converted to light energy, and 80 to 85% is converted into heat energy, and the temperature rise of the LED will cause its luminous efficacy to decline, and the degree of decline of yellow light is most significant, if the yellow LED light is from 25 degrees Celsius When the degree is increased to 100 degrees, the rate of decline will be as high as 75%. Therefore, if the LEDs are arranged side by side, the heat will not be easily dissipated, which will greatly affect the luminous efficacy, stability and service life of the LED.

In view of this, the author specially researched and improved the light guide strips, and improved the above problems with a better creation, and after a long period of research and development and continuous testing, the creation of this creation began.

Therefore, this creation is to solve the problem that some light rays will be directly or totally totally reflected by the end of the light guide body, resulting in loss of light and energy, and the light guide strips are arranged side by side, which makes the light source difficult. Heat dissipation causes a loss of luminous efficacy, stability, and age.
