Embodiment Construction

[0048] Figure 1A It is a schematic cross-sectional view of a light emitting device according to the first embodiment of the present invention. Please refer to Figure 1A , the light emitting device 100 of this embodiment includes a base 110 , a light emitting diode chip 120 , a wavelength conversion substance 130 and an encapsulant 140 .

[0049] The base 110 has a first groove 111 and a second groove 112 , and the second groove 112 is located above the first groove 111 . According to this embodiment, the material of the base 110 is, for example, an organic material (such as a polymer) or an inorganic material (such as glass, quartz, etc.). The method of forming the first groove 111 and the second groove 112 in the base 110 may adopt a molding method, a lithography and an etching process, or other suitable processes. In addition, the base 110 can be a strip-shaped base, and the first groove 111 and the second groove 112 are groove structures, so that the light emitting devic...

Abstract

The invention provides a light emitting device and a light source module. The light emitting device includes a pedestal, an LED chip, a wavelength converting substance and a packaging rubber material. The pedestal is provided with a first groove and a second groove and the second groove is arranged above the first groove. The LED chip is disposed in the first groove of the pedestal while the wavelength converting substance is disposed in the second groove of the pedestal. The packaging rubber material covers the LED chip. A gap is left between the wavelength converting substance and a side wall of the second groove to accommodate redundant rubber material, thereby preventing the rubber material from spilling.

Description

technical field [0001] The present invention relates to a light-emitting device, in particular to a light-emitting device with a wavelength conversion substance. Background technique [0002] Quantum Dots are extremely small semiconductor nanocrystals that cannot be seen by the naked eye, and are particles with a particle size of less than 10 nanometers. Generally speaking, quantum dots are composed of zinc, cadmium, selenium and sulfur atoms. Its characteristic is that whenever it is stimulated by light, the quantum dot will emit colored light, and the color of the light is determined by the composition material, size and shape of the quantum dot. This characteristic enables the quantum dot to change the color of the light emitted by the light source, so it can be used Classified as a type of wavelength conversion material (Wavelength Conversion Material). [0003] In terms of working principle, quantum dots are similar to YAG phosphors. The light stimulation of light emi...
