<p>A light regulatable Light Emitting Diode (LED) illumination lamp is disclosed by the invention. It includes LED illumination lamps, and further includes an Electro Magnetic Interference (EMI) circuit (1), a power factor correction circuit (2), a switching digital power circuit (3), a light regulation control circuit (4), a direct current power circuit (5), an alternating current signal sampling circuit (6), a Micro Controller Unit (MCU) (7), a Radio Frequency (RF) wireless transmitter (10), an RF reception circuit (8), an Electrically Erasable Programmable Read Only Memory (EEPROM) (9), and a fan circuit (11). Compared with the prior art, the invention has the following advantages: By using the light regulatable LED illumination lamp provided by the invention, the luminance of the LED illumination lamp can be regulated with any traditional incandescent lamp dimmer, or can be regulated with any common key switch, or further can be remotely regulated with a wireless transmitter, the lamp can be turned on or off remotely, and a luminance saving function is provided at the same time. The fan circuit implements heat radiation of the LED through air convection. The lamp provided by the invention has the advantages of beautiful appearance, small cubage, light weight, lower cost, long life, good heat radiation effect and so on.</p> |
