Embodiment 1

[0105] Embodiment 1, the first light emitting element 1 in the light source module L1 is a blue LED chip with Peak=450nm. 5.88 g of red fluorescent powder with the substitution number R640 is called as the third additional luminous body 203 . 2.14 g of yellow fluorescent powder with the substitution number Y565 was called as the second additional luminous body 202 . 0.38 g of green fluorescent powder named G-Ga535 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

[0106] Embodiment 2, the first light emitting element 1 in the light source module L1 is a blue LED chip with Peak=450nm. 8.45 g of red fluorescent powder with a substituting number of R650 is called as the third additional luminous body 203 . 1.65 g of yellow fluorescent powder with the substitution number Y565 was used as the second additional luminous body 202 . 0.48 g of green fluorescent powder with the substitution number G-L535 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

[0107] Embodiment 3, the first light emitting element 1 in the light source module L1 is a blue LED chip with Peak=445nm. 9.20 g of red fluorescent powder with a substituting number of R650 was called as the third additional luminous body 203 . 1.55 g of yellow fluorescent powder with the substitution number Y550 was used as the second additional luminous body 202 . 0.43 g of green fluorescent powder named G-L535 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 6 , see Table 3 for specific luminous properties.

Abstract

The invention discloses a light source module, and a lighting device comprising the light source module. The light source module comprises a first light-emitting element and a package part covered onthe first light-emitting element, the package part comprises a first additional luminous body, a second additional luminous body, and a third additional luminous body, the lights emitted from variousluminous bodies are mixed as the warm white light which is used as the emitting light of the light source module. The light source module provided by the invention provides the LED warm white light (3000K) light source with high lighting effect, low CS value and high color rendering at the same time by controlling the light-emitting energy in the 495-580nm wavelength region maximally influencing the CS value in the total light-emitting energy. The light with the low CS value is especially suitable for the leisure and entertainment of the people, and a relax light environment is provided for the people.

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 in the industry, and the spectrum with a low CS value is especially su...
