Abstract:
A lighting emitting diode (LED) lamp (100) includes a first LED array (60) and a second LED array (50). A rate of change of a relatively luminous intensity relative to the temperature of the first LED array is lower than that of the second LED array. A first heat sink (10) thermally attaches to the first LED array. A second heat sink (20) thermally attaches to the second LED array. A heat dissipation efficiency of the second heat sink is higher than that of the first heat sink. The heat dissipation of the second LED array is much quicker than that of the first LED array. The second LED array thus can be kept working at a much lower temperature.
