Problems solved by technology

On the other hand, the injection current of the laser diode must be greater than the critical current density, which is related to the interface temperature and indirectly affects the efficiency
When operating at high temperature, the critical current increases, the benefit decreases, and even the components are damaged

Abstract

The invention discloses a lighting device, which at least comprises a refrigeration chip, wherein the refrigeration chip is provided with a or a plurality of a laser diode chips and a or a plurality of lighting diode chips, wherein at least a laser diode and a lighting diode are arranged on the base. The lighting device can have characteristic illuminating of the laser diode when an extremely narrow spectrum frequency bandwidth is needed, and characteristic illuminating of the lighting diode which has better heat dissipating characteristics when the extremely narrow spectrum frequency bandwidth is not needed.

Description

technical field [0001] The present invention relates to light emitting devices. Specifically, the invention is a light-emitting device that can produce uniform luminosity, low divergence, and narrow frequency bandwidth. More specifically, the light-emitting device of the present invention is a light-emitting device comprising a cooling chip, at least one laser diode chip, and at least one light-emitting diode chip. Background technique [0002] Laser diodes have the advantages of small size, high efficiency, low power consumption, long service life, and easy modulation of their output power by the magnitude of the current. The scope of its application is related to the wavelength. Lasers with short wavelengths (390-950 nanometers) are mainly used for optical information and display purposes such as optical disc drives, laser printers, barcode machines, and scanners, while lasers with long wavelengths (980-1500 nanometers) Mainly used for optical fiber communication. The l...
