Abstract: A light-emitting device includes a lead frame, a light-emitting diode (LED) chip, and an encapsulant. The LED chip is disposed on the lead frame, and includes a substrate, a semiconductor light-emitting unit disposed on a surface of the substrate, and a first electrode and a second electrode, which are disposed on the surface of the substrate, and which are located outwardly of the semiconductor light-emitting unit. The first and second electrodes are electrically connected to a lower surface of the semiconductor light-emitting unit, and are respectively connected to a first wiring bonding region and a second wiring bonding region on the lead frame. The encapsulant encapsulates the LED chip on the lead frame.

Abstract: The present invention provides a white light LED package structure and a white light source system, which includes a substrate, an LED chip, and a wavelength conversion material layer. The peak emission wavelength of the LED chip is between 400 nm and 425 nm; the peak emission wavelength of the wavelength conversion material layer is between 440 nm and 700 nm, and the wavelength conversion material layer absorbs light emitted from the LED chip and emits a white light source; and the emission spectrum of the white light source is set as P(?), the emission spectrum of a blackbody radiation having the same color temperature as the white light source is S(?), P(?max) is the maximum light intensity within 380-780 nm, S(?max) is the maximum light intensity of the blackbody radiation within 380-780 nm, D(?) is a difference between the spectrum of the white light LED and the spectrum of the blackbody radiation, and within 510-610 nm, the white light source satisfies: D(?)=P(?)/P(?max)?S(?)/S(?max), ?0.

Abstract: A cabinet includes a base, a top frame, at least three vertical pillar assemblies which are disposed between the base and the top frame, a cover, and at least three side plates. The cover is disposed at a side of the top frame, that is opposite to the side facing the base. A vertical pillar assembly includes a pillar, an inner clamp, and an outer clamp, wherein the inner clamp includes a first and a second side edge, and the outer clamp includes a third and a fourth side edge. The pillar is clamped between the inner clamp and the outer clamp. Space between the first side edge and the third side edge of the outer clamp is used for clamping a side plate, and space between the second side edge and the fourth side edge of the outer clamp is used for clamping a side plate.
