Light emitting diode package
View Patent ↗There is provided a light emitting diode (LED) package in which a phosphor layer encapsulating an LED chip is formed uniformly to facilitate a process. The LED package includes: a package body having a mounting area; a holding part mounted on the mounting area to expose a portion of the mounting area; an LED chip mounted on the mounting area, the LED chip surrounded by the holding part to emit light; and a phosphor layer held by the holding part to seal a space defined by the holding part, the phosphor layer converting a wavelength of the light from the LED chip.
1. A light emitting diode package comprising:
a package body having a mounting area;
a light emitting diode chip mounted on the mounting area and emitting light;
a groove formed on the mounting area around the light emitting diode chip and surrounding the light emitting diode chip;
a holding part mounted on the mounting area and fixed in the groove, the holding part surrounding the light emitting diode chip and being open to expose a portion of the mounting area and the light emitting diode chip disposed in the holding part; and
a phosphor layer held by the holding part to seal a space defined by the holding part, the phosphor layer converting a wavelength of the light from the light emitting diode chip.
2. The light emitting diode package of claim 1 , wherein
the holding part is formed of a transparent material transmitting the wavelength-converted light.
3. The light emitting diode package of claim 2 , wherein
the light emitting diode package further comprises a lens focusing the wavelength-converted light.
4. The light emitting diode package of claim 3 , wherein
the phosphor layer has a refractivity greater than or equal to a refractivity of the holding part, and
the holding part has the refractivity greater than or equal to a refractivity of the lens.
5. The light emitting diode package of claim 4 , wherein
a protrusion is formed on an inner circumferential surface of the holding part surrounding the holding part, and
a transparent resin is formed between the phosphor layer and the light emitting diode chip, the transparent resin encapsulating the light emitting diode chip to prevent oxidation between a phosphor of the phosphor layer and the light emitting diode chip.
6. The light emitting diode package of claim 1 , wherein the groove is formed on the mounting area of the package body to secure the holding part insertedly fitted in the groove.
7. The light emitting diode package of claim 6 , wherein
the holding part comprises transparent silicon dispensed from a dispenser.
8. The light emitting diode package of claim 5 , wherein
the protrusion of the holding part has a height greater than a height of the light emitting diode chip and smaller than a height of the holding part, and
the transparent resin layer is formed to have a height from the mounting area of the package body to the protrusion.
