The invention discloses a flexible circuit substrate double-sided light-emitting LED array light source. The flexible circuit substrate double-sided light-emitting LED array light source comprises a plurality of LED chips. The flexible circuit substrate double-sided light-emitting LED array light source is characterized in that the flexible circuit substrate double-sided light-emitting LED array light source further comprises a flexible flat transparent circuit substrate, a conductive pattern and a fluorescent film; one side of the flexible flat transparent circuit substrate is provided with the conductive pattern; binding regions are reserved on the conductive pattern; the LED chips are directly arranged on the binding regions in a surface-mount manner and are communicated with one another through the conductive pattern; and the fluorescent film is arranged on the LED array such that the LED chips can be entirely encapsulated. With the flexible circuit substrate double-sided light-emitting LED array light source of the invention adopted, problems of low light-emitting efficiency and low light source utilization rate, which are caused by single-sided light emission of an LED light source in the prior art, can be solved; and the LED chips can be protected, and at the same time, PN junctions of the LED chips can be fully utilized to emit light; and advantages of a plane array source light can be utilized, and therefore, heat dissipation capacity can be improved, and cost and weight of a heat sink and a radiator can be omitted. Thus, the flexible circuit substrate double-sided light-emitting LED array light source is advantageous in improved light-emitting efficiency and improved utilization rate.
