[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.
[0029] The lamps in the related art use a single blue light chip to excite yellow phosphor, resulting in a spectral loss of the emitted light, leading to a discontinuous spectral distribution.
[0030] Please refer to Figures 1 to 3 together. The present utility model provides a lamp 1000. The lamp 1000 can be a light bulb, a lamp tube, a downlight, etc. For example, the lamp 1000 can be a globe lamp. The lamp 1000 includes a housing 200, a circuit board 11, a white light source 12, a first single blue light source 13, and a second single blue light source 14. The white light source 12, the first single blue light source 13, and the second single blue light source 14 are all assembled on the circuit board 11. The wavelength band of the first single blue light source 13 is different from that of the second single blue light source 14. Among them, the white light source 12, the first single blue light source 13, and the second single blue light source 14 can all be lamp beads.
[0031] In this way, the white light source 12 can be mixed with the first single blue light source 13 and the second single blue light source 14 with different wavelength bands to emit sunlight-like light, which helps to complement the blue light spectrum in the sunlight-like light, helps to improve the continuity of the sunlight-like light spectrum, and also makes the sunlight-like light spectrum closer to the solar spectrum.

[0035] Among them, the peak wavelengths and half-widths of the white light source 12, the first single blue light source 13, and the second single blue light source 14 can be appropriately adjusted within the corresponding ranges, and can be specifically selected according to the actual situation. For example, the peak wavelength of the white light source 12 can be 548 nm, and the half-width can be 260 nm; the peak wavelength of the first single blue light source 13 can be 464 nm, and the half-width can be 17 nm; the peak wavelength of the second single blue light source 14 can be 484 nm, and the half-width can be 17 nm.

[0037] In some embodiments, the radiation power ratio of the white light source 12, the first single blue light source 13, and the second single blue light source 14 is 98.9±10%: 2.2±10%: 0.5±10%.
[0038] In this way, it helps to ensure that the radiation power ratio of the white light source 12, the first single blue light source 13, and the second single blue light source 14 can be maintained within a suitable range, helps to improve the color rendering index of the lamp 1000, helps to improve the color rendering property of the lamp 1000, and also helps to improve the luminous efficacy of the lamp 1000 to meet the requirements of standard illumination illuminance.
[0039] Exemplarily, the radiation power ratio of the white light source 12, the first single blue light source 13, and the second single blue light source 14 can be 98.9: 2.2: 0.5, and can be specifically set according to the actual situation.
[0040] In some embodiments, in the white light source 12, the ratio of the spectral power between 380 nm and 530 nm to the total spectral power is 0.2328±0.005, the ratio of the spectral power between 530 nm and 548 nm to the total spectral power is 0.1763±0.005, and the ratio of the spectral power between 548 nm and 780 nm to the total spectral power is 0.5909±0.005.
[0041] In this way, it helps to reasonably distribute the ratio of the spectral power of different bands of the white light source 12 to the total spectral power, helps to improve the color rendering index and luminous efficiency of the white light source 12, and helps to improve the color rendering index and luminous efficiency of the lamp 1000.
[0042] Exemplarily, in the white light source 12, the ratio of the spectral power between 380 nm and 530 nm to the total spectral power is 0.2328, the ratio of the spectral power between 530 nm and 548 nm to the total spectral power is 0.1763, and the ratio of the spectral power between 548 nm and 780 nm to the total spectral power is 0.5909, and can be specifically set according to the actual situation.
[0043] In some embodiments, in the first single blue light source 13, the ratio of the spectral power in the wavelength band between 380 nm and 460 nm to the total spectral power is 0.2142 ± 0.005, the ratio of the spectral power in the wavelength band between 460 nm and 464 nm to the total spectral power is 0.1919 ± 0.005, and the ratio of the spectral power in the wavelength band between 464 nm and 780 nm to the total spectral power is 0.5939 ± 0.005.
[0044] Thus, it helps to reasonably distribute the ratio of the spectral power of different wavelength bands of the first single blue light source 13 in the total spectral power, helps to improve the luminous efficiency of the first single blue light source 13, and helps to improve the luminous efficiency of the lamp 1000.
[0045] Exemplarily, in the first single blue light source 13, the ratio of the spectral power in the wavelength band between 380 nm and 460 nm to the total spectral power is 0.2142, the ratio of the spectral power in the wavelength band between 460 nm and 464 nm to the total spectral power is 0.1919, and the ratio of the spectral power in the wavelength band between 464 nm and 780 nm to the total spectral power is 0.5939, which can be specifically set according to the actual situation.
[0046] In some embodiments, in the second single blue light source 14, the ratio of the spectral power in the wavelength band between 380 nm and 475 nm to the total spectral power is 0.0678 ± 0.005, the ratio of the spectral power in the wavelength band between 475 nm and 484 nm to the total spectral power is 0.3441 ± 0.005, and the ratio of the spectral power in the wavelength band between 484 nm and 780 nm to the total spectral power is 0.5881 ± 0.005.
[0047] Thus, it helps to reasonably distribute the ratio of the spectral power of different wavelength bands of the second single blue light source 14 in the total spectral power, helps to improve the luminous efficiency of the second single blue light source 14, and helps to improve the luminous efficiency of the lamp 1000.
[0048] Exemplarily, in the second single blue light source 14, the ratio of the spectral power in the wavelength band between 380 nm and 475 nm to the total spectral power is 0.0678, the ratio of the spectral power in the wavelength band between 475 nm and 484 nm to the total spectral power is 0.3441, and the ratio of the spectral power in the wavelength band between 484 nm and 780 nm to the total spectral power is 0.5881, which can be specifically set according to the actual situation.
[0049] In some embodiments, the color temperature range of the white light source 12 is 4000K to 6500K. In this way, the white light source 12 can be maintained at an appropriate color temperature, so that the light emitted by the white light source 12 can be close to natural white light, thereby making the color temperature of the sunlight-like light mixed by the white light source 12, the first single blue light source 13, and the second single blue light source 14 closer to the color temperature of natural white light, which helps to reduce the stimulation of the sunlight-like light to the human eye.
[0050] Exemplarily, the color temperature of the white light source 12 can be 4000K, 5000K, 5700K or other values within the color temperature range, which can be specifically set according to the actual situation.
[0051] Please refer to Figure 2 and Figure 7 In some embodiments, the number of the first single blue light source 13 and the second single blue light source 14 is equal, the number of the white light sources 12 is multiple and greater than or equal to the number of the first single blue light source 13, and the number of the white light sources 12 and the number of the first single blue light source 13 are in an integer multiple relationship. In the embodiments of the present application, when the single-source voltages of the first single blue light source 13, the second single blue light source 14, and the white light source 12 are the same, between different types of light sources, for example, between the first single blue light source 13 and the white light source 12, they can be connected in parallel, while between the same type of light sources, for example, between multiple white light sources 12 or between multiple first single blue light sources 13, they can be connected in series.
[0052] Exemplarily, the voltage of each of the first single blue light source 13, the second single blue light source 14, and the white light source 12 is 3V. As Figure 2 shown, the number of the first single blue light source 13 and the second single blue light source 14 can be set to 3 respectively, and the number of the white light sources 12 is 24, that is, the number of the white light sources 12 and the number of the first single blue light source 13 and the number of the second single blue light source 14 are in an eight-fold relationship. At this time, between the 3 first single blue light sources 13 and between the 3 second single blue light sources 14, they can be respectively connected in series to form two blue light paths, and the number of the white light sources 12 can be set to four white light paths, where each white light path includes 3 white light sources 12 connected in series. Thus, the voltage of each light path is the same, both are 9V, so that the four white light paths and the two blue light paths can be connected in parallel.
[0053] In this way, it helps to ensure that the load voltage of each light source in the circuit of the lamp 100 is constant. The lamp 100 does not need to boost or step down a certain light source in the circuit of the lamp 100 separately, which helps to simplify the structure of the circuit of the lamp 100, is convenient for manufacturing, and also helps to respectively match the power and output voltage between the white light source 12 and the first single blue light source 13, and between the white light source 12 and the second single blue light source 14. Therefore, it helps to ensure that the lamp 1000 has an appropriate power and output voltage, and helps to ensure the light-emitting effect of the lamp 1000.
[0054] It should be noted that in other embodiments, the first single blue light source 13 or the second single blue light source 14 and the white light source 12 can also be set to other integer multiples, which is not limited herein.
[0055] Among them, "a plurality" means two or more. For example, the number of the white light sources 12 can be two, three, four, twelve, twenty-four or other numbers, and can be specifically set according to the actual situation.
[0056] Exemplarily, as Figure 2 shown, the number of the white light sources 12 can be 24, and the numbers of the first single blue light source 13 and the second single blue light source 14 can both be 3; for another example, as Figure 7 shown, the number of the white light sources 12 can be 12, and the numbers of the first single blue light source 13 and the second single blue light source 14 can both be 1, which can be specifically set according to the actual situation, as long as the quantity relationship among the white light source 12, the first single blue light source 13 and the second single blue light source 14 is satisfied.
[0057] In some embodiments, the first single blue light source 13 and the second single blue light source 14 can be symmetrically distributed with respect to the white light source 12.
[0058] In this way, the white light source 12 can be mixed with the first single blue light source 13 and the second single blue light source 14 respectively, which helps to improve the mixing uniformity of the white light source 12 with the first single blue light source 13 and the second single blue light source 14, and thus helps to ensure the mixing uniformity of the lamp 1000.
[0059] Please refer to Figure 8 and Figure 9 together. In some embodiments, the lamp 1000 may further include a third single blue light source 15, the third single blue light source 15 is assembled on the circuit board 11, and the wavelength band of the third single blue light source 15 is different from the wavelength bands of the first single blue light source 13 and the second single blue light source 14.
[0060] In this way, the white light source 12 can be mixed with the first single blue light source 13, the second single blue light source 14 and the third single blue light source 15 with different wavelength bands to emit quasi-sunlight, which helps to complement the blue light spectrum in the quasi-sunlight and helps to improve the continuity of the quasi-sunlight spectrum.
[0061] In some embodiments, the peak wavelength range of the third single blue light source 15 is 450 nm to 460 nm, and the full width at half maximum range is 15 nm to 20 nm. In this way, it helps to ensure that the third single blue light source 15 can have a suitable peak wavelength, helps to improve the color rendering index of the lamp 1000, helps to improve the color rendering property of the lamp 1000, and also helps to improve the continuity and smoothness of the quasi-sunlight spectrum.
[0062] Exemplarily, the peak wavelength of the white light source 12 is 548 nm, and the full width at half maximum is 260 nm; the peak wavelength of the first single blue light source 13 is 464 nm, and the full width at half maximum is 17 nm; the peak wavelength of the second single blue light source 14 is 484 nm, and the full width at half maximum is 17 nm; the peak wavelength of the third single blue light source 15 is 455 nm, and the full width at half maximum is 17 nm. The white light source 12 can be mixed with the first single blue light source 13, the second single blue light source 14, and the third single blue light source 15 in a certain proportion to emit a solar-like light with a relatively continuous spectrum.
[0063] In the third single blue light source 15, the ratio of the spectral power in the wavelength band between 380 nm and 530 nm to the total spectral power is 0.1699 ± 0.005, the ratio of the spectral power in the wavelength band between 450 nm and 455 nm to the total spectral power is 0.2284 ± 0.005, and the ratio of the spectral power in the wavelength band between 455 nm and 780 nm to the total spectral power is 0.6017 ± 0.005.
[0064] Thus, it helps to reasonably distribute the ratio of the spectral power of different wavelength bands of the third single blue light source 15 to the total spectral power, helps to improve the luminous efficiency of the third single blue light source 15, and helps to improve the luminous efficiency of the lamp 1000.

[0066] Among them, the number of the third single blue light source 15 is equal to that of the first single blue light source 13 and the second single blue light source 14, and the number of the white light source 12 and the number of the third single blue light source 15 are in an integer multiple relationship, which can be specifically set according to the actual situation.
[0067] In other embodiments, the lamp 1000 may further include a fourth single blue light source, a fifth single blue light source, a sixth single blue light source, etc., which can be specifically set according to the actual situation.
