[13] The first phosphor layer 120 is coated on the first lens 110, and the second lens 130 is disposed on the first phosphor layer 120. The plurality of protective layers 150 is disposed on the second lens 130 in a trapezoidal shape. In this case, each of the protective layers 150 may be formed of transparent silicon gel and can serve to improve light transmittance while protecting the second lens 130 or the first phosphor layer 120.
[14] The second phosphor layer 140 is coated on a lateral surface of each of the protective layers 150, the reflection plate 160 is disposed on the second phosphor layer 140. The plurality of light-emitting diode (LED) devices 210 is disposed on the top surface of the protective layers 150 and the plurality of metal slugs 170 is disposed on the light- emitting diode (LED) devices 210.
[15] In this case, the first phosphor layer 120 and the second phosphor layer 140 comprise phosphor, and the light-emitting diode (LED) device 210 is a blue light-emitting diode (LED). The first phosphor layer 120, the second phosphor layer 140 and the light- emitting diode (LED) device 210 can be used to produce a white light source.

The environmentally-friendly layer 220 comprises magic stone, tourmaline, kaolin or elvan. When the heat generated from the light-emitting diode (LED) devices 210 is transferred to the environmentally- friendly layer 220 through the heat pipes 190, it can be emitted to the outside through the environmentally-friendly layer 220. At this time, the environmentally-friendly layer 220 can generate anions or far-infrared rays so as to create a pleasant environment.
