Problems solved by technology

[0005] If light leakage occurs on the side of a light emitting device applied to an automotive lamp, the cut-off line, which is the boundary between bright and dark portions generated when the light emitted from the automotive lamp is irradiated forward, cannot be clearly displayed
As a result, there is a problem that the driver irradiates light to an unnecessary area, possibly obstructing the view of other drivers, and there is a problem that light loss occurs because the light is released from the side of the light emitting device.

Abstract

The present invention relates to a light-emitting device. A light-emitting device according to one embodiment of the present invention comprises a substrate, a first light-emitting chip, a first wavelength conversion member, and a barrier member. The first light-emitting chip is mounted on the substrate. The first wavelength conversion member covers the upper surface of the first light-emitting chip. A first reflective member covers the side surface of the first wavelength conversion member. Further, the barrier member comprises an outer wall portion surrounding the side surfaces of the first light-emitting chip and the first reflective member.

Description

technical field [0001] The invention relates to a light emitting device. Background technique [0002] A light-emitting chip is a semiconductor element that emits light generated by recombination of electrons and holes, and recently, the light-emitting chip is utilized in various fields such as displays, automotive lamps, general lighting, and the like. Light-emitting chips have a long life, low power consumption, and fast response, so they are being used in various fields such as automotive lighting and display devices. [0003] figure 1 It is a cross-sectional view showing a conventional light-emitting device. refer to figure 1 , the existing light-emitting device 10 includes a light-emitting chip 11 , a wavelength conversion member 12 , a blocking member 14 and a circuit substrate 15 . The barrier member 14 is formed of a material containing a reflective substance in resin. Therefore, the blocking member 14 functions to reflect the light released from the light emitt...
