light emitting device

Abstract

The invention discloses a light emitting device. The light-emitting device includes a packaging structure, a first light-emitting chip, a second light-emitting chip, a third light-emitting chip, a first packaging colloid, a second packaging colloid and a third packaging colloid. The first light-emitting chip, the second light-emitting chip and the third light-emitting chip are arranged in the first cavity, the second cavity and the third cavity of the main body of the package structure, and are connected with the first electrode pair and the second electrode covered by the body. The two electrode pairs and the third electrode pair are electrically connected, and the first packaging gel, the second packaging gel and the third packaging gel are filled in the first container, the second container and the third container. The first opening of the first container is larger than the second opening of the second container, and the first opening of the first container is larger than the third opening of the third container.

Description

Technical field [0001] The present invention relates to a light emitting device, the light emitting device and particularly to a face recognition system applied to the monitoring system to capture or identification of the appropriate license. Background technique [0002] Existing face recognition system applied to the monitoring system to capture or identification of the license plate, which is mostly an infrared light emitting diode as a sensing light source. However, light emitted from the infrared light emitting diode will still fall within the scope portion in the red range, the conventional system will look bright red spot (erythema phenomenon), is easy to draw attention, not reach the desired effect or influence by monitoring passers security. [0003] To eliminate this phenomenon erythema, industry has been trying to infrared light emitting diode and the blue light emitting diode package in a single bowl PLCC6 cup holder, and phosphor was added thereto packaging adhesive ...

AI Technical Summary

Problems solved by technology

[0004] The invention discloses a light-emitting device, which is mainly used to improve the conventional light-emitting device used in a surveillance system for capturing human faces or a recognition system for license plate recognition. Since the packaging glue mixed with phosphor powder will not only lay on the blue light-emitting diode It will also be laid on the infrared light-emitting diode, so it will cause the problem of energy loss of infrared light
