Abstract

The invention provides a light emitting diode (LED) light source component and an LED lamp provided with the same. The light emitting diode (LED) light source component comprises a heat dissipating substrate, a blue and white LED mixed light source, a light transmitting carrier and remote excitation materials, wherein the blue and white LED mixed light source is arranged on the upper surface of the heat dissipating substrate; the light transmitting carrier is positioned above the blue and white LED mixed light source; and the remote excitation materials are arranged on the light transmitting carrier. The LED light source component provided by the invention controls the light emitting power through the blue and white LED mixed light source, and is further matched with the remote excitation materials to manufacture the high-color-rendering white LEDs at different color temperatures, so that a high-color-rendering white LED light source of which the color temperature is in the range of 2500K to 6000K can be obtained.

Description

technical field [0001] The invention relates to the field of LED optics, in particular to an LED light source assembly. In addition, the present invention also relates to an LED lamp comprising the above-mentioned light source assembly. Background technique [0002] At present, there are mainly two ways to realize high color rendering warm white LED lamps. One is to start from the light source and directly use warm white LEDs with a higher color rendering index as the light source; the other is to start from the light distribution design and add some Auxiliary light sources with long wavelengths (usually red light) are used to improve the overall color rendering index. In the former, warm white LEDs use blue light chips to excite yellow phosphors plus appropriate proportions of red phosphors. Due to the wide absorption area and wide emission spectrum of red phosphor, a large part falls outside the sensitivity curve of human eyes, so the overall luminous efficiency is low. ...
