Embodiment 1

[0134] Embodiment 1, the first light emitting element 1 in the light source module L1 is a blue LED chip with Peak=450nm. 1.45 g of red fluorescent powder with the substitution number R630 was used as the third additional luminous body 203 . The second additional illuminant 202 is composed of yellow phosphor powder code-named Y550 and green phosphor powder code-named G-Ga535, wherein 2.23g of yellow phosphor powder and 0.86g of green phosphor powder total 3.09g. 1.80 g of blue-green fluorescent powder with the substitution number BG490 was used as the first additional luminous body 201 . Put the above-mentioned fluorescent powder into transparent silica gel, and then fully mix it with a mixer, coat it on the blue LED chip, dry and remove air bubbles to obtain a neutral white LED chip, its spectrum is shown in Figure 4 , see Table 3 for specific luminous properties.

Embodiment 2

[0135] Embodiment 2, the first light emitting element 1 in the light source module L1 is a blue LED chip with Peak=450nm. 1.58 g of red fluorescent powder with the substitution number R630 was used as the third additional luminous body 203 . The second additional illuminant 202 is composed of yellow phosphor powder code-named Y550 and green phosphor powder code-named G-Ga535, wherein the yellow phosphor powder is 0.90g and the green phosphor powder is 1.98g, totaling 2.88g. 1.50 g of blue-green fluorescent powder with the substitution number BG490 was used as the first additional luminous body 201 . Put the above-mentioned fluorescent powder into transparent silica gel, and then fully mix it with a mixer, coat it on the blue LED chip, dry and remove air bubbles to obtain a neutral white LED chip, its spectrum is shown in Figure 5 , see Table 3 for specific luminous properties.

Embodiment 3

[0136]Embodiment 3, in the light source module L1, the first light emitting element 1 is a blue LED chip with Peak=455nm. 1.92 g of red fluorescent powder with the substitution number R640 was used as the third additional luminous body 203 . The second additional illuminant 202 is composed of a yellow phosphor coded Y565 and a green phosphor coded G-L535, wherein the yellow phosphor is 1.37g and the green phosphor is 1.57g, totaling 2.94g. 1.30 g of blue-green fluorescent powder with the substitution number BG490 was used as the first additional luminous body 201 . Put the above-mentioned fluorescent powder into transparent silica gel, and then fully mix it with a mixer, coat it on the blue LED chip, dry and remove air bubbles to obtain a neutral white LED chip, its spectrum is shown in Image 6 , see Table 3 for specific luminous properties.

Abstract

Disclosed are a light source module and an illuminating device using the same. The light source module comprises a first light-emitting element and a packaging part for covering the first light-emitting element; the packaging part comprises a first additional light-emitting body, a second additional light-emitting body and a third additional light-emitting body; light emitted by each of the lightemitting bodies is mixed to form warm white light, and the warm white light serves as emission light of the light source module. According to the light source module provided by the invention, the duty ratio of the light-emitting energy in the wavelength region of 495-560nm with the largest influence on the CS value in the total light-emitting energy is controlled; meanwhile, an LED neutral whitelight (4000k) light source with high light effect, high CS value and high color rendering performance is provided; and the light source is especially suitable for studying and working of concentratedattention under the same illuminance.

Description

technical field [0001] The invention relates to a light source module and a lighting device including the light source module. Background technique [0002] With the advent and development of the third lighting technology revolution, the production and sale of incandescent lamps and halogen lamps have been gradually banned by countries all over the world due to their low light efficiency and lack of energy saving. LED lighting appliances have been widely used instead. Existing LED lighting products mainly solve the problems of energy saving, illuminance, color and color rendering. When using LED lighting products, more and more people are concerned that there is more blue light in LEDs, which may affect the circadian rhythm of the human body. For the impact of lighting products on the circadian rhythm of the human body, we can use the Circadian StimuIus evaluation model to evaluate, that is, the CS value referred to in the industry. The spectrum with high CS value is especi...
