[0048] The light source module and lighting device proposed by the present invention are further described in detail below with reference to the accompanying drawings and some preferred embodiments consistent with the present invention.

[0049] A specific embodiment of the light source module L1 of the present invention is a mixed light white light LED package chip, which can be a LED chip with a general SMD package structure or a COB package structure such as Figure 1 As shown, the light source module L1 includes at least a first light emitting element 1 and a packaging portion 2 covering the first light emitting element.

[0050] First light-emitting element 1 is a blue LED chip, which emits light directly from semiconductor materials. Its peak wavelength is between 390 and 470 nm, and its color is purple or blue. The light emitted by first light-emitting element 1 is referred to herein as the first color light. LED chips can be either face-mounted or flip-mounted, and can be single or multiple connected in series, parallel, or both.

[0051] The packaging part 2 uses transparent silicone or transparent resin as a base material 204 , wherein the transparent resin can be selected from epoxy resin and urea resin. The first additional light-emitting part 201 and the second additional light-emitting part 202 are disposed in the base material 204 .

[0052] The first additional light-emitting portion 201 includes at least one green phosphor or yellow phosphor with a peak wavelength of 520~560nm, that is, the first additional light-emitting portion 201 receives part of the light emitted by the first light-emitting element 1 and converts it into a second color light with a peak wavelength of 520~580nm. Since color is an intuitive perception of the human body, it is impossible to accurately divide the spectral boundaries of yellow and green. Here we believe that green phosphor or yellow phosphor is only a difference in name. The two basically have the same chemical formula, and the only difference is the molar ratio of the components. In this application, the first additional light-emitting portion 201 can select a single yellow phosphor or green phosphor, or a plurality of yellow phosphors or green phosphors with peak wavelengths of 520~560nm can be selected and mixed to serve as the first additional light-emitting portion 201. The green phosphor and yellow phosphor can be aluminate system phosphors with the chemical formula Y3Al5O 12 :Ce 3+ 、Lu3Al5O 12 :Ce 3+ 、Y3(Al,Ga)5O 12 :Ce 3+ 、Tb3Al5O 12 :Ce 3+ Or it is a silicate system phosphor with the chemical formula (Ca, Sr, Ba) 2 (Mg, Zn) Si 2 O 7: Eu 2+ 、(Ca,Sr,Ba)2MgSi3O5:Eu 2+ 、β-(Sr,Ba,Ca)2SiO4:Eu 2+ 、α-(Sr,Ba,Ca)2SiO4:Eu 2+ ; Or it is a nitrogen oxide system phosphor, chemical formula β-(Sr,Ca)SiAlON:Eu 2+ 、α-(Sr,Ca)SiAlON:Eu 2+ The above molecular formula is a basic molecular formula. In actual applications of phosphors, the molar ratio is not very precise. Different molar ratios will affect the peak wavelength of the phosphor, which is understandable to those skilled in the art. In other preferred embodiments, the first additional light-emitting unit 201 can also be an LED chip with a peak wavelength between 520 and 580 nm, which is not limited in this application.

[0053] The second additional light-emitting portion 202 includes at least one red phosphor or orange phosphor with a peak wavelength of 610-660 nm, that is, the second additional light-emitting portion 202 receives part of the light emitted by the first light-emitting element 1 and converts it into a third color light with a peak wavelength of 610-660 nm, preferably 630-660 nm, and a half-width of 80-100 nm. In the present application, the second additional light-emitting portion 202 can select a single red phosphor or orange phosphor, or a plurality of red phosphors or orange phosphors with a peak wavelength of 520-560 nm can be selected and mixed to serve as the second additional light-emitting portion 202. The red phosphor and the orange phosphor are nitride system phosphors with the chemical formula (Sr, Ba) 2 Si 5 N 8: Eu 2+ 、(Sr,Ca,Ba)SiAlN3:Eu 2+ In some other preferred embodiments, the second additional light emitting unit 202 may also be an LED chip with a peak wavelength between 610 and 660 nm, or the second additional light emitting unit 202 may include both an LED chip and phosphor, which is not limited in this application.

[0054] The encapsulation portion 2 may also include a light diffuser 203, which may be one of nano-sized titanium oxide, aluminum oxide, or silicon oxide. In this embodiment, the weight ratio of the combined weight of the phosphors used as the first additional light-emitting portion 201 and the second additional light-emitting portion 202 to the base material 204 is 50% to 120%, with the weight ratio of the second additional light-emitting portion 202 to the first additional light-emitting portion 201 being 10% to 60%, preferably 25% to 40%. The weight ratio of the light diffuser 203 to the base material 204 is less than 3.0%. The various types of phosphors and light diffusers are weighed proportionally and mixed into the base material 204. The mixture is then thoroughly stirred in a blender to uniformly distribute the phosphors and light diffusers throughout the base material 204. After removing any bubbles, a dispensing machine is used to apply the base material 204 mixed with the phosphors to the LED chip used as the first light-emitting element 1, forming the encapsulation portion 2.

[0055] The light source module L1 after packaging is a mixture of the first color light emitted by the first light emitting element 1, the second color light emitted by the first additional light emitting portion 201, and the third color light emitted by the second additional light emitting portion 202. The light source module L1 proposed in this application emits light with a color temperature of 1450K~1750K, and the distance Duv between it and the black body locus BBL on the CIE1931 chromaticity diagram is between [-0.005, 0.005]. Figure 2More preferably, the color of the emitted light is located in the ellipse with the center point x0=0.571, y0=0.402, major axis a=0.00229, minor axis b=0.00129, inclination angle θ=38.7°, and SDCM=5.0 on the CIE1931 color space. Figure 2 It is represented as area A1 in the figure.

[0056] The light emitted by the light source module L1 also has the following characteristics: the maximum spectral intensity of the emitted light is located in the range greater than 610nm, that is, the red light segment forms a first peak; the range of 390~470nm in the emitted light spectrum, that is, the blue light segment forms a second peak, wherein the peak intensity of the second peak is less than or equal to 12.0% of the peak intensity of the first peak, preferably less than or equal to 8.0% of the peak intensity of the first peak. Such a spectral distribution is as follows Figure 3 Compared with the typical warm white light in the prior art, the blue light has less energy and a yellowish color, making it more suitable for nighttime use.

[0057] At the same time, the emission spectrum of the light source module L1 is continuous and very close to the blackbody radiation spectrum of the same color temperature and brightness in the range of 380~660nm. To illustrate this similarity, this application defines the similarity S as follows:

[0058]

[0059] A(λ) is the spectral distribution of the emitted light;

[0060] P(λ) is the blackbody radiation spectrum distribution with the same color temperature as the emitted light.

[0061] The similarity S between the emitted light of the light source module L1 and the blackbody radiation spectrum of the same color temperature and brightness is ≥78%, and the preferred similarity S is ≥85%.

[0062] The light emitted by light source module L1 should have a melanopsin illuminance to photopic illuminance ratio (M / P) ≤ 0.20, preferably ≤ 0.16. Light colors with these characteristics can promote rapid sleep onset. Traditionally, it was believed that there are two types of photoreceptor cells in the retina: one capable of distinguishing brightness and darkness, and the other capable of distinguishing color. In bright conditions, only cones function, and this state of vision is called photopic vision. The curve that plots cone sensitivity by spectral frequency is called the photopic sensitivity curve. Scientists now believe that a third type of photoreceptor cell exists in the retina: melanopsin-producing retinal ganglion cells (ipRGCs). ipRGCs are responsible for sensing light intensity and transmitting signals to the pineal gland. The pineal gland in the human brain secretes a hormone called melatonin, a "natural sleeping pill" and the body's natural "rest signal." High levels of melatonin in the body make us drowsy, while low levels keep us alert. The curve that divides the sensitivity of ipRGCs according to spectral frequency is called the melanopsin light sensitivity curve.

[0063] The specific formula for the ratio of melanopsin illuminance to photopic illuminance, M / P, is as follows:

[0064]

[0065] A(λ) is the spectral distribution of the emitted light;

[0066] Mel(λ) is the melanopsin light sensitivity curve;

[0067] V(λ) is the photopic vision sensitivity curve.

[0068] The above describes a specific embodiment of the present application. Several specific examples employing this embodiment are described below. Table 1 shows six examples of the present application, along with the selection of the first light-emitting element 1, the first additional light-emitting portion 201, and the second additional light-emitting portion 202, as well as the peak wavelength of the light generated in each example. The table also indicates the weights of the phosphor, the diffuser 203, and the base material 204.

[0069] Table 1

[0070]

[0071] As can be seen from Table 1, for the first light-emitting element 1, the six embodiments provided in this application all use a blue chip, but the peak wavelength of the chip selected in each embodiment is different. The first additional light-emitting portion 201 in embodiments 1 to 4 is a yellow phosphor with an aluminate structure, and the molecular formula is Y3Al5O 12 :Ce 3+Although the molecular formula is the same, the model used in Example 1 is different from that in Examples 2 to 4, so their peak wavelengths are also different. Example 5 is an aluminate structure green phosphor with a molecular formula of Y3(Al,Ga)5O 12 :Ce 3+ , with a peak wavelength of 535nm. Example 5 is an aluminate structure green phosphor with a molecular formula of Lu3Al5O 12 :Ce 3+ , with a peak wavelength of 535nm. The second additional light emitting portion 202 in Examples 1 to 6 is all made of the same type of nitride red phosphor, with the molecular formula being (Sr, Ca, Ba)SiAlN3:Eu 2+ , the luminescence peak wavelengths are different, and are marked as 1, 2, and 3 in the table. In Examples 1 to 4, nano-TiO2 is used as a light diffusing agent, while in Examples 5 and 6, no light diffusing agent is added.

[0072] The weights of the phosphors in the examples in Table 1 are all data from when we made the sample chip of the light source module L1. In actual mass production, the weights will vary slightly due to different batches of phosphors. However, in order to ensure the realization of the specific light color and spectral characteristics proposed in this application, their basic proportions are within a fixed range. The wt2 / wt1 in Table 1 represents the weight ratio of the second additional light-emitting portion 202 to the first additional light-emitting portion 201. The ratio in the table is basically within the range of 30% to 35%. Taking into account the different batches of phosphors, the actual range may be expanded to 25% to 40%. If a different type of phosphor is selected from the example, the total ratio range may be expanded to 10% to 60%. However, basically speaking, the red and orange phosphors used as the second additional light-emitting portion 202 are less than the yellow and green phosphors used as the first additional light-emitting portion 201. (wt1+wt2) / wt3 represents the weight ratio of the sum of the weights of the phosphors serving as the first additional light-emitting portion 201 and the phosphors serving as the second additional light-emitting portion 202 to the base material 204. The values in the table are basically between 90% and 100%. Also, considering the different types of phosphors, the actual range may be expanded to 50% to 120%.

[0073] In addition to the above embodiments, the present application also provides another preferred embodiment. In this embodiment, the second additional light-emitting portion 202 includes not only a red or orange phosphor but also a red LED chip. The phosphor and the chip work together to enhance the energy of the red light portion to ensure that the peak intensity of the second wave peak is less than or equal to the peak intensity of the first wave peak. According to this embodiment, the present application also provides Example 7, in which the first light-emitting element 1 is a blue LED with a peak wavelength of 408nm. The first additional light-emitting portion 201 is a yellow phosphor with an aluminate structure and a peak wavelength of 565nm, and the molecular formula is Y3Al5O 12 :Ce3+ The second additional light emitting portion 202 includes a red phosphor of a nitride system with a peak wavelength of 635 nm and a molecular formula of (Sr, Ca, Ba)SiAlN3:Eu 2+ The powder weighs 2.63g. The second additional light emitting unit 202 also includes a red LED with a peak wavelength of 660nm. The base material 204 is a transparent silicone weighing 10g.

[0074] The positions of the light colors of the emitted light of Examples 1-7 on the CIE1931 color space are as follows: Figure 2 shown. Figure 4 、 Figure 6 、 Figure 8 、 Figure 10 、 Figure 12 、 Figure 14 、 Figure 16 The relative spectral energy distribution diagrams of Examples 1-7 are respectively, Figure 5 、 Figure 7 、 Figure 9 、 Figure 11 、 Figure 13 、 Figure 15 、 Figure 17 The following are comparisons of Examples 1-7 and reference spectra, where each reference spectrum is a blackbody radiation spectrum distribution with the same color temperature as the emitted light of the corresponding Example. The luminous characteristics and spectral characteristics of the emitted light of Examples 1-7 are shown in Table 2.

[0075] Table 2

[0076]

[0077] Rows 1-7 in Table 2 correspond to Examples 1-7, and row 8 corresponds to Figure 3 The luminous characteristics of typical warm white light in the prior art. The x and y columns in the table respectively represent the coordinate values of the light color of the light emitted by the light source module L1 on the x and y axes in the CIE1931 color coordinate system. The specific positions of each embodiment on the CIE1931 color coordinate system are as follows: Figure 2 As shown, we found that all points fall within the interval enclosed by the points with a distance duv = -0.005 to 0.005 from the blackbody locus between the correlated color temperature of 1450~1750K, that is, in the area A2 shown in the figure. After conducting user experiments on these embodiments later, we found that the effects of embodiments 1-4 were better, and Figure 2 We can find that these points all fall into the area A1 shown in the figure. Area A1 is an ellipse with the center point x0=0.571, y0=0.402, major axis a=0.00229, minor axis b=0.00129, inclination angle θ=38.7°, and SDCM=5.0.

[0078] In Table 2, CCT is the color temperature, and duv represents the distance and direction of the color deviation from the Planckian locus in the color coordinate system. Similarity S and M / P are calculated using the calculation formulas in this application document. In each embodiment, similarity S is greater than 78%, and for the more preferred embodiments 1-4, similarity S is greater than 82%. M / P is also less than 0.16. In the table, I2 / I1 represents the ratio of the peak intensity of the second peak to the peak intensity of the first peak. It can be seen that in each embodiment, the peak intensity of the second peak is less than or equal to 12.0% of the peak intensity of the first peak. CRI is the color rendering index. From Table 2, we can see that the emitted light of the light source module L1 in all embodiments has a high color rendering index, CRI ≥ 80.0.

[0079] The light source module L1 can be applied to various lamps. Figure 18 A lighting device D1 according to a preferred embodiment of the present application is shown. The lighting device D1 is a lamp panel, and in other preferred embodiments it can also be a chandelier, a ceiling lamp, etc., or the light source module L1 can also be applied to various types of lamps such as table lamps, downlights, and spotlights. The lighting device D1 includes a chassis 6, a surface frame 8 provided with a diffusion plate 9, a light source module L1 provided on the light source panel 5, and a power supply module 7 that provides the light source module L1 with the power required for operation. The lighting device D1 can also be provided with a controller, a heat dissipation device, and a light distribution component, etc., according to the function and requirements of the specific lamp. The controller can be used to adjust the light color, light intensity, etc. of the illumination light emitted by the light source module L1, and the light distribution component can be a lampshade, a lens, a diffusion element, a light guide, etc. in addition to the diffusion plate in the embodiment. This application does not limit this.

Obviously, many modifications and changes may be made, which may be obvious to those skilled in the art and should be included within the scope of the present application as defined by the appended claims.
