    Abstract: A light-emitting device includes multiple light-emitting diode units sequentially connected and coupled to a first power source, a switching circuit connected to the light-emitting diode units, a second power source, and a control module. Power provided by the first power source is larger than power provided by the second power source. The second power source is connected to the light-emitting diode units through the switching circuit, which is controlled by the control module to facilitate the delivery of the power of the first power source or the second power source to the light-emitting diode units. When the first power source serves to deliver the power thereof to the light-emitting diode units, the light-emitting diode units may be in a serial conduction. When the second power source serves to deliver the power thereof to the light-emitting diode units, the light-emitting diode units may be in a parallel conduction.

    Abstract: An off-axis light-emitting device and an image capturing module using the same are provided. The off-axis light-emitting device includes a substrate, a light-emitting chip, and an optical element. The substrate has a mounting surface, and the light-emitting chip for generating a light beam has a light output surface. The light-emitting chip is disposed on the assembly surface. The optical element is disposed on the assembly surface and includes a dome portion. The dome portion is arranged in an optical path of the light beam and extends in a first direction to form an elongated shape. The dome portion has a first reference plane that passes through two opposite side surfaces of the dome portion, and the first reference plane is offset from a geometric center of the light-emitting chip in a second direction, so that the light beam passing through the dome portion forms an off-axis projection light.

    Abstract: An LED package structure includes a ceramic substrate, a ceramic board, a light-emitting unit, a first adhesive layer, a second adhesive layer, and a cover. The ceramic board having a thru-hole is disposed on the ceramic substrate. The light-emitting unit is disposed on the ceramic substrate and is arranged in the thru-hole of the ceramic board. The first and second adhesive layers are disposed on the ceramic board, and the second adhesive layer covers the first adhesive layer. The cover is fixed on the ceramic board by the first and second adhesive layers. Thus, the shearing force of the LED package structure of the instant disclosure is increased by having the first and second adhesive layers, which are connected to each other.
