Abstract (en)
A light emitting diode (LED) lamp device (100) includes a lamp holder (200) including a power module (210), an LED module (310) and a shield (400, 402-405). The LED module (310), disposed on the lamp holder (200), is electrically connected to the power module (210). The shield (400, 402-405), disposed on the lamp holder (200), covers the LED module (310). The material of the shield (400, 402-405) is solid. The shield (400, 402-405) has a top portion (410), a lateral portion (420), an accommodating space (470), and an inner rough surface (430) and an outer surface (440) opposite to each other. The composition of the shield (400, 402-405) includes a light diffusing powder. The lateral portion (420) is connected to the lamp holder (200). The thickness of the top portion (410) is greater than that of the lateral portion (420). The thickness of the shield (400, 402-405) is substantially and gradually increased from the lateral portion (420) towards the top portion (410). The LED module (310) is located in the accommodating space (470), and the inner rough surface (430) faces the accommodating space (470).
