Problems solved by technology

However, since the LED itself is not an ideal point light source, the light emitted from the LED will not be modulated by the micro-groove structure as expected
In addition, the device for making the micro-groove structure is not popular

Embodiment Construction

[0084] In order to have a further understanding and understanding of the characteristics, purpose and functions of the present invention, the relevant structure and design concept of the system of the present invention are described below, and the detailed statements are as follows:

[0085] see Figure 2A as well as Figure 2B As shown, the figure is a perspective view and a schematic cross-sectional view of the first preferred embodiment of the light source packaging structure of the present invention. The light source packaging structure 2 includes: a light source accommodating portion 20 , a first refraction surface 21 and at least one second refraction surface 22 . The light source accommodating portion 20 can accommodate a light source body 9 . The first refraction surface 21 covers the light source body 9 to receive the light generated by the light source body 9 to form a first refraction light. The top of the first refraction surface 21 has a tapered surface 210 . T...

Abstract

The invention relates to a packaging structure for light source, comprising an accommodator for light source, a first refracting surface and at least a second refracting surface. The accommodator for light source can accommodate a light source body. The first refracting surface can receive the beam generated by the light source body to form a first refracting light and a refracting structure is set at the top of the first refracting surface. At least a second refracting surface can receive the first refracting light to form an exit light, which can leave the packaging structure for light source, and there is an angle between the normal vector of the second refracting surface and the mandrel of packaging structure for light source. In the invention above mentioned structure is used to generate multiple packaging structures so as to improve the effect of light deflection. The technology in invention is applied as the packaging structure of light emitting diode so that the beam jetted by light emitting diode deflects to the direction with bigger angle by multiple deflections. It can be applied in the area of flat light source and provides multiple usages.

Description

technical field [0001] The present invention relates to a packaging structure, in particular to a light source packaging structure which can generate large-angle deflection by making light refracted multiple times. Background technique [0002] In the structure of the current large-size backlight module of the display, a cold cathode tube (Cold Cathode Fluorescent Lamp, CCFL) is mainly used as the backlight source to illuminate the liquid crystal panel. However, with the progress of light-emitting diode technology, it is an irresistible trend to use light-emitting diodes as backlight sources for large-size liquid crystal displays. Compared with cold-cathode tubes, light-emitting diodes have the following advantages: (1) Light-emitting diodes are smaller than cold-cathode tubes and are not easily broken, which is helpful for system assembly. In addition, the light-emitting module assembled with light-emitting diodes has the advantages of lightness and thinness. (2) Light-em...
