发明名称 LED DEVICE AND MANUFACTURING METHOD THEREOF
摘要 Provided is an LED device which is compact while having good luminous efficiency and a focused light distribution. This LED device is provided with: a reflective frame around the outer periphery of the LED device; an LED die which has a transparent insulating substrate, a semiconductor layer formed on the bottom surface of the transparent insulating substrate, and an outer connection electrode disposed on the semiconductor layer; and a fluorescent member which is disposed on at least the top surface of the LED die and which converts the wavelength of the light emitted from the LED die. On the inside of the reflective frame is an inclined surface in contact with the lateral surface of the fluorescent member, and the inclined surface is formed such that the inner diameter of the reflective frame widens from the bottom surface towards the top surface of the LED die. Also provided is a manufacturing method of the LED device.
