', ' send the first - polar light bar. Fluorescent powder conversion light-emitting diode element 106 insect 108 古古τη 姑 "The same light spectrum, that is to say, the light-emitting 扒 conversion light-emitting diode element 106 first Thai polar body element m color temperature. In a practical light powder In the embodiment of the conversion illuminating light source, the light source module 100 can include only a fluorescent powder conversion LED component 106 and a phosphor powder conversion LED component 1 〇8, wherein the phosphor powder is converted into two light-emitting diodes. The polar body component 1〇6 is adjacent to the phosphor-converted light-emitting diode element 1〇8 to facilitate light mixing. In the exemplary embodiment, the light source module 100 includes a plurality of phosphor-converted light-emitting diode elements 106. And a plurality of phosphor-converting light-emitting diode elements 1〇8, wherein the phosphor-switching light-emitting diode elements 106 and 1 are preferably arranged in a staggered manner on the surface 104 of the carrier 1〇2. As shown in Fig. 1. In one embodiment, the phosphor-converted light-emitting diode elements 丨〇6 and 1 〇8 φ are both white light-emitting diode elements, but only the phosphor-converted light-emitting diode elements. The spectrum of light emitted by 10ό is different from that of fluorescent powder conversion LED components 1〇8 The spectrum of the emitted light. Referring to FIG. 2A, the phosphor-converting light-emitting diode element 1〇6 may mainly include a blue light-emitting diode die 1〇6a and a yellow fluorescent layer 106b′ The layer i〇6b is overlaid on the blue light emitting diode die 106a. On the other hand, as shown in FIG. 2B, the phosphor converted light emitting diode element 108 may also include at least the blue light emitting diode die 108a. And a yellow phosphor layer i 〇 8b, wherein the yellow phosphor layer i 〇 8b ^ is overlaid on the blue light emitting diode die 108a. In an embodiment, as shown in FIG. 3A, the phosphor powder is converted into two The blue light emitting diode die i〇6a of the polar body element 106 has an emission spectrum 110a' and the yellow fluorescent powder in the yellow fluorescent layer i〇6b has an emission spectrum 110b 'where the yellow fluorescent light in the yellow fluorescent layer 106b The powder emits yellow light after excitation by the light emitted by the blue light-emitting diode die 106a. On the other hand, as shown in FIG. 3B, the phosphor-converted light-emitting diode element 1〇8 blue light-emitting diode crystal The particle 108a has an emission spectrum 112a, and the yellow phosphor in the yellow fluorescent layer 108b has The light spectrum 112b, in which the yellow phosphor of 1363844 in the yellow fluorescent layer 108b is excited by the light emitted by the blue light emitting diode die 1083, emits yellow light. From Figs. 3A and 3B, although the phosphor powder The conversion LED elements 106 and 108 are both white light emitting diode elements, but the thickness or phosphor content of the yellow phosphor layers 106b and 10b are different from each other, for example, the phosphor content of the yellow glory layer 106b or The density is higher than the phosphor content of the yellow phosphor layer 1〇8b. Since the yellow phosphor layer 106b of the phosphor powder conversion LED element 1〇6 contains more phosphor powder, the yellow phosphor powder emits light. The intensity of the spectrum 110b is higher than the intensity spectrum of the blue light emitting diode die 106a ll 〇 a strength ' although the phosphor converted light emitting diode element 1 〇 6 is a white light emitting diode element, but due to the spectral intensity of the yellow light It is stronger than the blue light spectrum, so the phosphor converted light-emitting diode element 106 is actually a white light yellow-emitting light-emitting diode element.
