Problems solved by technology

Lamps currently used in school classrooms usually only consider indicators such as color temperature and illuminance, and there is no LED lighting product that can improve students' concentration by increasing the CS value and can take into account energy saving, illuminance, color, and color rendering

Embodiment 1

[0145] Embodiment 1, the first light emitting element 1 in the light source module L1 is a blue LED chip with Peak=450nm. 1.35 g of red fluorescent powder with the substitution number R630 was used as the third additional luminous body 203 . The second additional luminous body 202 is composed of a yellow fluorescent powder code-named Y565 and a green fluorescent powder code-named G-L535, wherein the yellow fluorescent powder is 0.66g and the green fluorescent powder is 1.32g. 1.60 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 10.00g of transparent silica gel, then fully mix it with a mixer, coat it on the blue LED chip, dry and remove air bubbles to obtain a positive white LED chip, its spectrum is shown in Figure 4 , see Table 3 for specific luminous properties.

Embodiment 2

[0146] Embodiment 2, the first light-emitting element 1 in the light source module L1 is a blue LED chip with Peak=455nm. 1.88 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 0.65g and the green phosphor powder is 2.22g. 1.51 g of blue-green fluorescent powder with the substitution number BG490 was called as the first additional luminous body 201 . Put 0.1g of the above-mentioned fluorescent powder and light diffusing agent nano-titanium oxide into 10.00g of transparent silica gel, then fully mix them evenly with a mixer, coat them on the blue LED chip, dry and remove air bubbles to obtain a positive white LED chip, its spectrum is shown in Figure 5 , see Table 3 for specific luminous properties.

Embodiment 3

[0147] Embodiment 3, in the light source module L1, the first light emitting element 1 is a blue LED chip with Peak=450nm. 1.44 g of red fluorescent powder with a substituting number of R630 is called as the third additional luminous body 203 . The second additional illuminant 202 is composed of yellow phosphor powder code-named Y565 and green phosphor powder code-named G-Ga535, wherein the yellow phosphor powder is 0.86g and the green phosphor powder is 1.27g. 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 10.00g of transparent silica gel, then fully mix it with a mixer, coat it on the blue LED chip, dry and remove air bubbles to obtain a positive white LED chip, its spectrum is shown in Image 6 , see Table 3 for specific luminous properties.

Abstract

The invention discloses a light source module and a lighting device using the same. The light source module comprises a first light-emitting element and a packaging part covering the first light-emitting element, wherein the packaging part comprises a first additional light-emitting body, a second additional light-emitting body and a third additional light-emitting body; and light emitted by the light-emitting bodies is mixed into positive white light, which serves as emitted light of the light source module. According to the light source module provided by the invention, the ratio of light-emitting energy in different wavelength regions to total light-emitting energy is controlled, so that a high-light-efficiency, high-CS-value and high-color-rendering LED positive white light (5,000K) source is provided. A high-CS-value light spectrum is especially suitable for people to pay attention to learn and work 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 lighting may have an impact on 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 especially suitable for pe...
