Problems solved by technology

[0003] However, the technology of applying LED package components to projectors as a projection light source has not yet matured, because the general LED package components have a light divergence angle of about 110 to 120 degrees, and the LED package components have no special mechanism design Assembled in the projector, the light source emitted by the LED packaging component cannot be effectively concentrated, and the light cannot be accurately aligned with the lens design of the optical system of the projector, which affects the optical path design of the optical system and the effective use of the light source.

Abstract

The invention provides a light-emitting diode (LED) packaging structure, which comprises a shell, an LED, a transparent assembly and an enclosed wall. The shell is provided with an upper surface, a groove formed on the upper surface, and a surrounding surface surrounding an opening of the groove; the LED is arranged on a bottom surface of the groove; the transparent assembly is arranged on the surrounding surface and seals the opening of the groove; and the enclosed wall is arranged on the upper surface of the shell and surrounds the transparent assembly.

Description

technical field [0001] The present invention relates to a light emitting diode (light emitting diode, LED) packaging structure, in particular to a light emitting diode packaging structure that can integrate light path design. Background technique [0002] The use of projectors has been widely used in daily life. For example, in general conference briefing occasions, the projector can be used to display the content of the report so that all participants can watch the data at the same time; or when watching movies at home, you can also Using the projector to project images, users can have theater-like enjoyment in their own living room. In addition, with the advancement of technology, the main types of digital projectors on the market include: cathode ray tube (cathode ray tube, CRT) projectors, liquid crystal display (liquid crystal display, LCD) projectors, digital light processing (digital light processing, DLP) projectors, liquid crystal on silicon (LCOS) projectors and o...
