Abstract
The invention relates to a warm light LED (Light Emitting Diode) light source. The warm light LED light source comprises a paraboloidal substrate and a plurality of other colors of LEDs which are arranged on the substrate. Light mixing is performed on at least one 580 to 780 nm wavelength of LED and the plurality of other colors of LEDs to obtain a warm light LED. The use of low-efficiency red phosphors is avoided due to the introduction of the 580 to 780 nm wavelength of LED and accordingly the integral light emitting efficiency of the warm light LED light source can be high. The obtained warm light LED light source can be greatly improved in the aspects of such as the lighting effect and the color rendering due to the effect of the basic paraboloid.
