Abstract: An LED lamp has an LED device and a lamp base. The LED device has multiple LED chips, multiple conductive substrates, a packaging layer and a protective cover. The multiple conductive substrates are arranged at intervals. Each of the LED chips is supported by and electrically connected between two adjacent conductive substrates.
