Problems solved by technology
[0004] In order to solve the problem of sticking between the surface packaging adhesive and the light guide plate after the expansion of the light-emitting diode after heating, it is a feasible solution to shrink the outer edge of the light guide plate to increase the distance between the light guide plate and the light-emitting diode. However, the existing The luminance and uniformity of the LED light source structure must be redesigned, otherwise, the existing LED light source structure will have new problems of insufficient luminance and decreased uniformity

Embodiment Construction
[0016] The following will clearly illustrate the spirit of the present invention with the accompanying drawings and detailed descriptions. After understanding the preferred embodiments of the present invention, any person of ordinary skill in the art can make changes and modifications based on the technology disclosed in the present invention, and without departing from the spirit and scope of the present invention.
[0017] Please refer to figure 1 , which shows a structural schematic diagram of the light-emitting diode and the light guide plate in the light-emitting diode light source. The light guide plate 100 is used for refracting and diffusing the light incident from the light source and emitting it uniformly. A light bar 102 is disposed outside one side 108 of the light guide plate 100 , and the light bar 102 has a light emitting diode 104 thereon. Light emitting diode 104 emits light with figure 1 The direction of the arrow shown is incident on the side 108 of the l...

The invention provides a light source structure of a light emitting diode, which is suitable for a backlight module of a liquid crystal display device. The light source structure is characterized by at least comprises a light bar provided with at least a light emitting diode, a strip-like jig arranged on the light bar and provided with at least one through hole and a light cup. The through hole is exposed outside the light emitting diode and the light cup is provided with an upper opening and a lower opening. The lower opening is connected in the periphery of the through hole. By adopting the invention, the distance from the light emitting diode to a light guide plate is increased to solve permanent damage caused by contact of the packaging glue material expanded by heat of the light emitting diode and the light guide plate and to reduce the light intensity abridged by scattering phenomenon caused by increase of the distance so that the brightness and the uniformity are maintained on the original level.
Description
technical field [0001] The invention relates to a light source structure, in particular to a light emitting diode light source structure suitable for a backlight module of a liquid crystal display device. Background technique [0002] In order to meet the needs of light and thin LCD, the light source will be placed on the side of the panel. At present, the widely used light source is light-emitting diode, which has the advantages of energy saving, environmental protection, long life, low power consumption, low heat, high brightness, and miniature. However, different from cold cathode ray tubes, light-emitting diodes are point light sources. Therefore, in order to change point light sources into line light sources and surface light sources, light guide plates have emerged as the times require. The light guide plate is made of optical-grade acrylic sheet, and then printed with light-guiding points on the bottom surface of the optical-grade acrylic sheet with a high-tech materi...
