[0014] The technical scheme of the present application will be further specifically described below by embodiments and in combination with the drawings.

[0015] Referring to Figure 1 The multifunctional spectrum lamp of the present application includes a driving module 1, an LED light source 2, an aluminum substrate 3, a lens 4, an embedded software module 5 and the like.

[0016] The aluminum substrate 3 serves as the main support component of the lamp, on which an LED light source 2 and a driving module 1 are provided, and a lens 4 is installed on the LED light source 2. As shown in the figure, the LED light source 2 is composed of four independent light source modules of different primary colors. The first light source module 21, the second light source module 22, the third light source module 23, and the fourth light source module 24 form a "field" shape. The current control of each light source module is independent of each other. The embedded software module 5 includes a spectrum simulation display module 51 and a transmission module 52. The embedded software module can be installed in a remote control or an APP. Consumers can input the spectrum and optoelectronic parameters required for the current usage scenario through the remote control or the APP. The spectrum simulation display module 51 is used to generate a spectrum fitting data based on the spectrum and optoelectronic parameters set for each of the light source modules, and transmit it to the driving module 1 through the transmission module 52. The transmission module 52 can use Bluetooth or WiFi. The driving module 1 is fixed on the aluminum substrate 3. The driving module 1 is electrically connected to the LED light source through the aluminum substrate, and controls and adjusts the power supply current ratio of each of the light source modules according to the spectrum fitting data.

[0017] The drive is provided with 4 channels, which respectively control the first to fourth light source modules one by one. The spectrum of each module is controlled by the current of the corresponding channel, and different current ratios will result in different overall fitted spectra.

[0018] Among them, the first light source module 21 is a light source that excites blue-violet phosphor with a chip having a wavelength of 315 - 365 nm; the second light source module 22 is a blue phosphor light source excited by a 365 - 385 nm chip; the third light source module 23 is a green phosphor light source excited by 445 - 465 nm; the fourth light source module 24 is a red phosphor light source excited by 445 - 465 nm.

[0019] Preferably, among them: the blue-violet phosphor is Ba3Sr 2-x (PO4)3 Cl:xEu 2+ , and 0.001 ≤ x ≤ 0.007. The x value represents the concentration of rare earth Eu 2+ . Too low concentration will result in too few luminescent centers and too low luminescence intensity, and too high concentration will cause the emission wavelength to be too long. This patent optimizes this range to just control the peak wavelength of the phosphor between 410 - 425 nm.

[0020] The blue phosphor is Sr 5-x (PO4)3Cl:xEu 2+ , a mixture of 0.01 ≤ x ≤ 0.07 and BaSi2O2N2:Eu. The x value mainly controls the wavelength and luminescence intensity. Too low x value will result in too short wavelength and low luminescence intensity, and too high x value will cause concentration quenching and reduced luminescence intensity. The above ratio is the optimal ratio. Among them, Sr5-x (PO4)3 Cl:xEu 2+ The weight mixing ratio of BaSi2O2N2:Eu and Ba3Sr2SiO4(PO4)3 Cl:xEu is in the range of 5:1 to 10:1. The mixing of the two is mainly to broaden the spectral continuity between the 440-520nm waveband. Too small a ratio will result in too low a blue light spectrum, and too high a ratio will result in too low a cyan light spectrum, which is not conducive to subsequent spectrum regulation. When the ratio is between the above ratios, the spectrum is most easily regulated.

[0021] The green fluorescent powder is Lu3Al5O 12 :Ce, with a peak wavelength of 520-530nm and a half-peak width of 110-150nm; and the red fluorescent powder is (Ca, Sr) AlSiN3:Eu, with a peak wavelength of 645-665nm and a half-peak width of 90-150nm. The peak intensity of the chip in the above four primary color light sources is all absorbed by the fluorescent powder, and the relative intensity of the chip peak is less than 1%, which can avoid the interference caused by spectrum fitting.

[0022] Example 1:

[0023] Example 1 mainly includes a first light source module, a second light source module, a third light source module, and a fourth light source module. Among them:

[0024] The first light source module is a light source with a chip wavelength of 335nm exciting a peak wavelength of 405nm fluorescent powder, and the chemical composition is Ba3Sr 2-x (PO4)3 Cl:xEu 2+ (x=0.003);

[0025] The second light source module is a peak wavelength of 460nm blue fluorescent powder light source excited by a 365nm chip, and the chemical composition is Sr 5-x (PO4)3 Cl:xEu 2+ , x=0.05 and the mixture of BaSi2O2N2:Eu, the mass ratio of the two is 6:1;

[0026] The third light source module is a peak wavelength of 525nm green fluorescent powder light source excited by a 452nm chip, and the chemical composition is Lu3Al5O 12 :Ce;

[0027] The fourth light source module is a peak wavelength of 650nm red fluorescent powder light source excited by a 452nm chip, and the chemical composition is a mixture of (Ca, Sr) AlSiN3:Eu and Y3(Al, Ga)5O 12 :Cr 3+ ;

[0028] When the current ratio of the first light source to the fourth light source module is 1:2:5:8, the color temperature is 2700K, and the spectrum is as follows: Figure 3as shown; when the current ratio of the first light source module to the fourth light source module is 3:4:2:2, the color temperature is 5000K, and the spectrum is as shown Figure 3 .

[0032] The second light source module is a 385nm chip excitation peak wavelength 450nm blue fluorescent powder light source, and the chemical composition is Sr5-x(PO4)3Cl:xEu 2+ , x=0.05 and BaSi2O2N2:Eu mixed, the mass ratio of the two is 7:1;

[0033] The third light source module is a 452nm excitation peak wavelength 525nm green fluorescent powder light source, and the chemical composition is Lu3Al5O 12 :Ce;

[0034] The fourth light source module is a 452nm excitation peak wavelength 650nm red fluorescent powder light source, and the chemical composition is (Ca, Sr) AlSiN3:Eu.

[0035] When the current ratio of the first light source module to the fourth light source module is 1:2:4:7, the color temperature is 3000K, and the spectrum is as shown Figure 4 ; when the current ratio of the first light source module to the fourth light source module is 1:2:3:6, the color temperature is 4000K, and the spectrum is as shown Figure 4 ; when the current ratio of the first light source module to the fourth light source module is 3:7:2:3, the color temperature is 6500K, and the spectrum is as shown Figure 4 . The spectrum of each module is controlled by the current of the corresponding channel, and different current ratios will result in different overall spectra.

[0036] As described above, the multifunctional spectrum lamp of the present application can be applied to various human factor lighting or special lighting scenes, such as rhythm lighting / full spectrum lighting / plant lighting and various forms.
