Abstract

The invention relates to a light-emitting device which comprises a circuit board, a light-emitting element, a light-condensing element and glue, wherein the circuit board is provided with a plurality of penetration holes, and a first surface and a second surface which are opposite mutually; each penetration hole is provided with a first pathway and a second pathway; each first pathway is formed by the extension of the first surface into the circuit board; each second pathway is formed by the extension of the second surface into the circuit board and is communicated with one of the first pathways; the accommodating space of each second pathway is larger than the accommodating space of the corresponding first pathway; the light-emitting element is electrically connected to the first surface and is configured on the first surface; the light-condensing element is provided with a plurality of positioning posts; part of light-condensing element is configured on the light-emitting element; each positioning post penetrates through one of the first pathways and is positioned within the corresponding second pathway; the glue is configured in the second pathways to fix each positioning post in the corresponding penetration hole. The light-emitting device provided by the invention has a better optics performance.

Description

【Technical field】 [0001] The present invention relates to a light emitting device, and in particular to a projector with the light emitting device. 【Background technique】 [0002] Patents such as Taiwan Patent Publication Nos. M358248, M362415 and M261399 disclose various light emitting devices. However, the light emitting device applied to the projector is specially designed to provide a light beam with higher brightness and occupy less configuration space. [0003] A conventional projector includes an illumination system, a light valve and an imaging system. The illumination system is adapted to emit an illumination beam. The light valve is located on the transmission path of the illumination beam and is adapted to convert the illumination beam into an image beam. The imaging system is located on the transmission path of the image beam, and a projection lens of the imaging system is suitable for projecting the image beam onto a screen. [0004] The lighting system inclu...
