도 3은 본 발명에 따른 백색 발광 다이오드를 도시한 발광 부위 확대도로써, 도 3을 참조하여 동작원리를 상세하게 설명하면,3 is an enlarged view of a light emitting part showing a white light emitting diode according to the present invention. Referring to FIG.
발광 소자의 활성층(211)에서 발생된 빛은 발광 소자와 발광 소자를 보호하고 외부형태를 구현하는 몰드재(213) 사이의 굴절률의 차이가 커서 내부반사율이 커지게 되어 발광 소자의 위부분인 몰드재 방향보다는 이면인 투과율이 큰 투명기판(212) 방향으로 굴절이 되므로 BASE구조물과 발광 소자 사이에 형광물질(214)을 도포하거나 매개체를 이용하여 얇게 밑면 또는 측면에 배치시킴으로써, 발광 소자에서 발생된 빛이 형광제를 거치면서 LED광과 다른 파장의 형광을 발생시킴으로써 원하는 파장의 빛을 얻을 수가 있다.The light generated from the active layer 211 of the light emitting device has a large difference in refractive index between the light emitting device and the mold material 213 that protects the light emitting device and implements an external shape, thereby increasing the internal reflectivity, thereby forming a mold that is the upper part of the light emitting device. Since the light is refracted in the direction of the transparent substrate 212 having the backside rather than the redirection, the fluorescent material 214 is applied between the BASE structure and the light emitting device, or is disposed on the bottom or side by using a medium to generate a light emitting device. As the light passes through the fluorescent agent, it generates fluorescence at a wavelength different from that of the LED light, thereby obtaining light having a desired wavelength.
또한, 이렇게 함으로써 발광 소자에서 발생된 빛을 발광 소자의 상단부에서 형광물질과의 파장변화에 의해서 발산시키는 광보다 발광효율이 높고 형광제의 형광재질 농도 조정으로 효과적인 색온도 조정을 할 수 있다.In addition, the light emitting efficiency is higher than the light emitted from the light emitting device by the wavelength change with the fluorescent material at the upper end of the light emitting device, and the color temperature of the fluorescent material can be effectively adjusted by adjusting the concentration of the fluorescent material.
따라서, 이러한 원리를 이용함으로써 본 발명에 의해서 청색계열의 발광 소자를 이용하여 편리하게 백색 발광 다이오드를 제조할 수 있으며,Therefore, by using this principle, a white light emitting diode can be conveniently manufactured using a blue light emitting device according to the present invention.
형광제와 접착제를 혼합사용시 기존의 백색 발광 다이오드 제조공정시에 추가되는 형광제 도포공정을 줄임으로써 제조원가를 절감할 수 있다.When the fluorescent agent and the adhesive are used in combination, manufacturing cost can be reduced by reducing the fluorescent agent coating process added during the existing white light emitting diode manufacturing process.

For example, the shape and structure of the elements of each component specifically shown in the embodiment of the present invention can be modified.
본 발명에 의한 형광제를 이용한 백색 발광 다이오드는 발광 소자에서 이면으로 굴절되어진 빛과 발광 소자와 발광 소자의 밑면에 배치된 형광제를 이용하여 발광 소자에서 발산된 빛과 발광 소자의 밑면 또는 측면에 배치된 형광제 사이에서 혼합된 빛이 발광됨으로써 발광효율이 높으며 형광 접착제의 형광재질 농도 조정으로 효과적인 색온도 조정이 가능하며 접착제와 형광제를 혼합 사용시 종래의 기술에서 설명한 형광제 도포의 공정이 줄어들므로 제조원가가 절감되는 효과가 있고,The white light emitting diode using the fluorescent agent according to the present invention is a light that is refracted to the back of the light emitting device and the light emitted from the light emitting device and the bottom or side of the light emitting device by using a fluorescent agent disposed on the bottom of the light emitting device. The luminous efficiency is increased by emitting light mixed between the disposed fluorescent agents, and the color temperature of the fluorescent adhesive can be adjusted effectively by adjusting the concentration of the fluorescent material, and when the adhesive and the fluorescent agent are mixed, the process of applying the fluorescent agent described in the prior art is reduced. Has the effect of reducing manufacturing costs,
