Abstract

A light emitting apparatus includes an array module including a first light emitting device which emits a light of a second color tinged with a first color, and a second light emitting device which emits a light of a fourth color tinged with a third color complementary to the first color of lights emitted from the first light emitting device.

Claims

exact text as granted — not AI-modified
1 . A light emitting apparatus comprising:
 an array module comprising a first light emitting device which emits a light of a second color tinged with a first color; and   a second light emitting device which emits a light of a fourth color tinged with a third color complementary to the first color of lights emitted from the first light emitting device.   
     
     
         2 . The light emitting apparatus of  claim 1 , wherein the first color is a blue color, the third color is a yellow color, and the second and fourth colors are a white color. 
     
     
         3 . The light emitting apparatus of  claim 1 , further comprising a third light emitting device emitting a light of a sixth color tinged with a fifth color. 
     
     
         4 . The light emitting apparatus of  claim 1 , wherein the array module includes the at least one first light emitting device and the at least one second light emitting device arrayed therein, and includes at least one third light emitting device adjacent to the at least one first light emitting device and the at least one second light emitting device. 
     
     
         5 . The light emitting apparatus of  claim 1 , wherein the first light emitting device has a driving voltage or a light intensity different from a driving voltage or a light intensity of the second light emitting device. 
     
     
         6 . The light emitting apparatus of  claim 1 , further comprising a light guide plate disposed at one side of the array module including the first and second light emitting devices, and a bottom cover including the array module and the light guide plate. 
     
     
         7 . The light emitting apparatus of  claim 1 , further comprising at least one optical sheet disposed on the array module including the first and second light emitting devices. 
     
     
         8 . The light emitting apparatus of  claim 1 , wherein the first and second light emitting devices include an LED chip and a phosphor excited by a light emitted from the LED chip to emit a light having a different wavelength. 
     
     
         9 . A light emitting apparatus comprising:
 an array module comprising a first light emitting device including a first LED chip and a first phosphor; and   a second light emitting device including a second LED chip and a second phosphor,   wherein the second light emitting device emits a light of a second mixed color complementary to a first mixed color of lights emitted from the first light emitting device in a same color band.   
     
     
         10 . The light emitting apparatus of  claim 9 , wherein the first and second phosphors include at least one selected from the group consisting of yellow, red, green, and orange phosphors. 
     
     
         11 . The light emitting apparatus of  claim 9 , wherein the array module includes the at least one first light emitting device and the at least one second light emitting device arrayed therein, and includes at least one third light emitting device adjacent to the at least one first light emitting device and the at least one second light emitting device. 
     
     
         12 . The light emitting apparatus of  claim 9 , wherein the first light emitting device has a driving voltage or a light intensity different from a driving voltage or a light intensity of the second light emitting device. 
     
     
         13 . The light emitting apparatus of  claim 9 , further comprising a light guide plate disposed at one side of the array module including the first and second light emitting devices, and a bottom cover including the array module and the light guide plate. 
     
     
         14 . The light emitting apparatus of  claim 9 , further comprising at least one optical sheet disposed on the array module including the first and second light emitting devices. 
     
     
         15 . The light emitting apparatus of  claim 9 , wherein the second light emitting device includes at least one selected from the group consisting of a light emitting device emitting a yellowish white light, a light emitting device emitting a reddish white light, and a light emitting device emitting a greenish white light. 
     
     
         16 . A display apparatus comprising:
 a light emitting apparatus including a first light emitting device emitting a bluish white light and a second light emitting device emitting a light complementary to the light emitted from the first light emitting device;   a light guide plate emitting a surface light source by using a light irradiated from the light emitting device;   an optical sheet disposed on the light guide plate;   a reflective sheet disposed under the light guide plate; and   a display panel disposed on the optical sheet.   
     
     
         17 . The display apparatus of  claim 16 , wherein the second light emitting device includes at least one of a light emitting device emitting a yellowish white, a light emitting device emitting a reddish white light, and a light emitting device emitting a greenish white light. 
     
     
         18 . The display apparatus of  claim 16 , wherein the first and second light emitting devices include a blue LED chip and a yellow phosphor excited by a light emitted from the blue LED chip to generate a light having a different wavelength. 
     
     
         19 . The display apparatus of  claim 17 , wherein the first and second light emitting devices include a blue LED chip and a yellow phosphor excited by a light emitted from the blue LED chip to generate a light having a different wavelength.
