Ultraviolet light emitting diode package
View Patent ↗An ultraviolet light emitting diode package for emitting ultraviolet light is disclosed. The ultraviolet light emitting diode package comprises an LED chip emitting light with a peak wavelength of 350 nm or less, and a protective member provided so that surroundings of the LED chip is covered to protect the LED chip, the protective member having a non-yellowing property to energy from the LED chip.
1. An ultraviolet light emitting diode (UV LED) package, comprising:
an LED chip to emit light with a peak wavelength of 350 nm or less;
a protective member covering the LED chip, the protective member comprising a material comprising a non-yellowing property to energy from the LED chip;
a heat dissipation member to radiate heat produced from the LED chip to an outside, wherein the heat dissipation member comprises:
a heat sink support ring comprising at least two connecting terminals; and
a heat sink inserted into the heat sink support ring, wherein the at least two connecting terminals are separated from the heat sink and the heat sink support ring.
2. The UV LED package as claimed in claim 1 , wherein the LED chip emits light with a peak wavelength of 320 nm or less.
3. The UV LED package as claimed in claim 1 , wherein the LED chip emits light with a peak wavelength of 280 nm or less.
4. The UV LED package as claimed in claim 1 , wherein the LED chip is disposed on top of the heat sink.
5. The UV LED package as claimed in claim 1 , further comprising a package body supporting the lead terminals and the heat sink support ring.
6. The UV LED package as claimed in claim 5 , wherein the at least two connection terminals extend through a side surface of the package body.
7. The UV LED package as claimed in claim 5 , wherein the heat sink support ring extends through a side surface of the package body.
8. The UV LED package as claimed in claim 1 , wherein the protective member comprises silicon resin that contacts and seals the LED chip.
9. The UV LED package as claimed in claim 1 , wherein a portion of the UV LED package, onto which light from the LED chip reflects, comprises aluminum.
10. The UV LED package as claimed in claim 1 , wherein the at least two connecting terminals are electrically isolated from each other.
11. The UV LED package as claimed in claim 10 , wherein each of the at least two connecting terminals comprises a wire connected to the LED chip.
12. The UV LED package as claimed in claim 1 , wherein an upper surface of the heat sink support ring and an upper surface of the at least two connecting terminals is substantially coplanar, and wherein the upper surfaces contact the protective member.
13. The UV LED package as claimed in claim 12 , wherein an upper surface of the heat sink contacts the protective member.
