Description

Technical Field

[0001] The present invention relates to the technical field of lighting, and in particular, to a light source and a lamp. Background Art

[0002] Lighting fixtures play a very important role in people's life and work. The spectrum of the light source included in the lighting fixture is an important factor determining the light efficiency of the lighting fixture. Generally, under the state of natural light, the comfort of people's eyes is relatively the best. Therefore, the closer the spectrum of the light source within the wavelength range of 380 nm to 780 nm is to the spectrum of natural light, the more complete the spectrum of the light source is, the lower the stimulation of the lighting fixture to people's eyes is, the more comfortable people will feel during use, and it can achieve a good effect of protecting eyesight.

[0003] Currently, the common light source in lighting fixtures is the LED (Light-Emitting Diode Light) light source, which has the characteristics of low cost and low energy consumption. Moreover, the energy consumption of the LED lamp is only one-tenth of that of the incandescent lamp and one-fourth of that of the energy-saving lamp, so it is widely used in life and work scenarios. In common LED lamps, the emitted spectrum can be close to the natural light spectrum within the wavelength range of 380 nm to 700 nm.

[0004] However, for the above light source, the light intensity in the wavelength range of 700 nm to 780 nm is weak, resulting in a low and weak spectrum of the light source in the 700 nm - 780 nm wavelength range, which affects the light efficiency of the lighting fixture. Summary of the Invention

[0005] The present invention provides a light source and a lamp to solve the problem that in the existing lighting fixtures, the light intensity of the light source in the wavelength range of 700 nm to 780 nm is weak, resulting in a low and weak spectrum of the light source in the 700 nm - 780 nm wavelength range and affecting the light efficiency of the lighting fixture.

[0006] The first aspect of the present application provides a light source, including a first light-emitting component and a second light-emitting component;

[0007] The spectrum of the first light-emitting component is a spectrum including at least 380 nm to 700 nm, and the spectrum of the second light-emitting component is a spectrum of 700 nm to 785 nm.

[0008] The light source consists of a first light-emitting component and a second light-emitting component. That is, the light emitted by the light source is a combined light of the light emitted by the first light-emitting component and the light emitted by the second light-emitting component. The spectrum of the first light-emitting component is in the range of 380nm - 700nm, and the spectrum of the second light-emitting component is in the range of 700nm - 785nm. Then the spectrum of the light emitted by the light source is in the range of 380nm - 785nm, achieving at least the supplementation of the spectrum in the range of 700nm - 780nm, solving the problem of the low and weak spectrum of the existing light source in the range of 700nm - 780nm, making the spectrum of the light source close to the full spectrum, that is, the spectrum of the light source is close to the spectrum of natural light, thereby effectively improving the light efficiency of the light source and enhancing the protection effect of the light source on the human eye.

[0009] In a possible implementation manner, the second light-emitting component includes a first light-emitting element, a second light-emitting element, a third light-emitting element, and a fourth light-emitting element;

[0010] The spectrum of the first light-emitting element is a first segmented spectrum, the spectrum of the second light-emitting element is a second segmented spectrum, the spectrum of the third light-emitting element is a third segmented spectrum, and the spectrum of the fourth light-emitting element is a fourth segmented spectrum;

[0011] The first segmented spectrum, the second segmented spectrum, the third segmented spectrum, and the fourth segmented spectrum are sequentially connected to form a spectrum in the range of 700nm - 785nm.

[0012] In a possible implementation manner, the first segmented spectrum is a spectrum in the range of 700nm - 721nm;

[0013] The second segmented spectrum is a spectrum in the range of 720nm - 741nm;

[0014] The third segmented spectrum is a spectrum in the range of 740nm - 761nm;

[0015] The fourth segmented spectrum is a spectrum in the range of 760nm - 785nm.

[0016] In a possible implementation manner, the ratio of the power of the first light-emitting component, the power of the second light-emitting component, the power of the third light-emitting component, and the power of the fourth light-emitting component is (1 - 5) : (1 - 5) : (1 - 5) : (1 - 5).

[0017] In a possible implementation manner, the ratio of the power of the first light-emitting component, the power of the second light-emitting component, the power of the third light-emitting component, and the power of the fourth light-emitting component is 1 : 1 : 1 : 1.

[0018] In a possible implementation manner, the ratio of the power of the first light-emitting component, the power of the second light-emitting component, the power of the third light-emitting component, and the power of the fourth light-emitting component is 1 : 1 : 2 : 1.

[0019] In a possible implementation, the first light-emitting element, the second light-emitting element, the third light-emitting element, and the fourth light-emitting element are monochromatic red light or infrared lamp beads;

[0020] The red lamp bead is an LED lamp bead excited by a chip in the 700nm - 785nm band.

[0021] In a possible implementation, the light intensities of the first light-emitting element, the second light-emitting element, the third light-emitting element, and the fourth light-emitting element are all greater than 0.3.

[0022] In a possible implementation, the ratio of the power of the first light-emitting component to the power of the second light-emitting component is (1 - 20):1.

[0043] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0044] Figure 1 It is a spectral diagram of sunlight, Figure 2 and it is a spectral diagram of the light source in an existing LED lamp.

[0045] With the continuous development and progress of lamps, lamps are no longer simply used for lighting. People have begun to pay more attention to the impact of lighting lamps on the eyes. Since the human eye has adapted to the natural light environment during the long-term evolution process, in the natural light environment, the human eye is less stimulated, the comfort of the eyes is better, and it also has a certain protective effect on eyesight.

[0046] Refer to Figure 1 as shown. The figure shows a spectral diagram of natural light. Among them, the abscissa is the wavelength, and the ordinate is the luminous intensity of the light. From Figure 1It can be known that the spectrum of natural light has a certain intensity within the wavelength range of 380nm to 780nm. The human eye is most comfortable under the illumination corresponding to this spectrum, and it helps to protect people's eyes.

[0047] Regarding how lighting fixtures can achieve the natural lighting effect, it has always been the research direction of lighting fixtures. Lighting fixtures usually include a light source, which is used for emitting light. The spectrum of the light emitted by the light source is one of the important factors determining the light efficiency of the lighting fixture. That is to say, the spectrum of the light emitted by the light source has a response within 380nm to 780nm. The closer the spectrum of the light source is to natural light and the more complete the spectrum of the light source is, the better the light efficiency of the corresponding lighting fixture will be. In this way, when people use the lighting fixture, the stimulation of the lighting fixture to the human eye will be lower, the comfort of the eyes will be better, and it can play a good role in protecting eyesight.

[0048] Currently, due to its characteristics of low cost and energy consumption, LED light sources are widely used in lighting fixtures. See Figure 2 As shown, the spectrum of the light source of a common LED lamp can have a good response within the wavelength range of 380nm to 700nm, which is relatively close to natural light. However, in the wavelength range of 700nm to 780nm, the intensity of the light emitted by the light source is relatively weak, and the luminous intensity of the light is less than 0.1, resulting in a low and weak spectrum of the light source in the 700nm to 780nm wavelength range, thus seriously affecting the light efficiency of the lighting fixture.

[0049] Based on the above problems, the present application provides a light source that can achieve the supplementation of the spectrum in the 700nm to 780nm wavelength range, so that the spectrum of the light emitted by the light source is a spectrum of 380nm to 785nm, and the spectrum of the light source is close to the spectrum of natural light, thereby effectively improving the light efficiency of the lighting fixture.

[0050] Figure 3 It is a schematic structural diagram of a light source provided by an embodiment of the present application.

[0051] An embodiment of the present application provides a light source 100. The light source 100 can be an LED light source, and the light source 100 can be used in a variety of lighting devices, such as indoor lighting fixtures, outdoor lighting fixtures, vehicle lights, table lamps, or flashlights, etc.

[0052] See Figure 3As shown, the light source 100 includes a first light-emitting component 10 and a second light-emitting component 20. Among them, the spectrum of the first light-emitting component 10 is at least the spectrum between 380 nm and 700 nm, that is, the light emitted by the first light-emitting component 10 has better intensity (at least greater than 0.2) between 380 nm and 700 nm. Specifically, for example, the first light-emitting component can be an existing LED lamp, that is, the spectrum of the first light-emitting component can have better response within the 380 nm - 700 nm band, while the spectral response is weak between 700 nm and 780 nm. Or, the first light-emitting component can also have only spectral response within the 380 nm - 700 nm band and no spectral response in other bands.

[0053] Among them, the spectrum of the second light-emitting component 20 is the spectrum of 700 nm - 785 nm, that is, the light emitted by the second light-emitting component 20 has better intensity (at least greater than 0.2) between 700 nm and 785 nm.

[0054] And the light source 100 is composed of the first light-emitting component 10 and the second light-emitting component 20, that is, the light emitted by the light source 100 is the combined light of the light emitted by the first light-emitting component 10 and the second light-emitting component 20. The spectrum of the first light-emitting component 10 is the spectrum in the 380 nm - 700 nm band, and the spectrum of the second light-emitting component 20 is the spectrum in the 700 nm - 785 nm band. Then the spectrum of the light emitted by the light source 100 is the spectrum of 380 nm - 785 nm, realizing the supplementation of at least the spectrum in the 700 nm - 780 nm band, solving the problem of the low and weak spectrum of the existing light source in the 700 nm - 780 nm band, making the spectrum of the light source 100 close to the full spectrum, that is, the spectrum of the light source 100 is close to the spectrum of natural light, thereby effectively improving the light efficiency of the light source 100, enhancing the color rendering degree of the light source 100, and enhancing the protection effect of the light source 100 on the human eye.

[0055] Among them, it should be noted that the first light-emitting component 10 can be a light source made by a specific chip exciting phosphor, or the first light-emitting component 10 can also be other light sources, as long as it can emit light with a spectrum of at least including 380 nm - 700 nm.

[0056] For example, the first light-emitting component 10 can be a light source made by a violet chip exciting a mixed phosphor. Specifically, the mixed phosphor can include a blue phosphor, a green phosphor, and a red phosphor. The blue phosphor, the green phosphor, and the red phosphor can be mixed in a certain proportion. Under the violet light emitted by the violet chip, the blue phosphor, the green phosphor, and the red phosphor can emit blue light, green light, and red light respectively. The blue light, the green light, the red light, and the violet light emitted by the violet chip are mixed, and its spectrum can be at least the spectrum between 380 nm and 700 nm.

[0057] The first light-emitting component 10 may be composed of one type of light-emitting element, or the first light-emitting component 10 may also be a light-emitting assembly formed by combining two or more types of light-emitting elements. In the embodiments of the present application, the specific composition of the first light-emitting component 10 is not limited, as long as the spectrum of the first light-emitting component 10 includes at least the spectrum from 380 nm to 700 nm.

[0058] In the embodiments of the present application, the second light-emitting component 20 may also be a light source made of a specific chip exciting phosphor, capable of emitting a spectrum from 380 nm to 700 nm.

[0059] In a possible implementation manner, for example, the second light-emitting component 20 may be a light source made of a blue chip exciting red phosphor. The red phosphor can emit red light under the excitation of blue light, and the mixed light formed by the red light and the blue light emitted by the blue chip may have a spectrum in the range of 700 nm to 785 nm.

[0060] Specifically, continue to refer to Figure 3 As shown, the second light-emitting component 20 is composed of four light-emitting elements. For example, the four light-emitting elements are the first light-emitting element 21, the second light-emitting element 22, the third light-emitting element 23, and the fourth light-emitting element 24 respectively.

[0061] Among them, the spectrum of the first light-emitting element 21 is the first segmented spectrum, the spectrum of the second light-emitting element 22 is the second segmented spectrum, the spectrum of the third light-emitting element 23 is the third segmented spectrum, and the spectrum of the fourth light-emitting element 24 is the fourth segmented spectrum.

[0062] The first segmented spectrum, the second segmented spectrum, the third segmented spectrum, and the fourth segmented spectrum are connected in sequence to form a spectrum from 700 nm to 785 nm. That is, four light-emitting elements are used respectively, and the spectra of the four light-emitting elements can correspond to four parts in the range of 700 nm to 785 nm. After combining the four light-emitting elements, the second light-emitting component 20 can emit a spectrum in the range of 700 nm to 785 nm. For example, the range from 700 nm to 785 nm can be divided into four connected segments, and then the spectra of the first light-emitting element 21, the second light-emitting element 22, the third light-emitting element 23, and the fourth light-emitting element 24 can correspond to the above four segments respectively. In other words, through the segmented supplementation by the four light-emitting elements respectively, the supplementation of the range from 700 nm to 785 nm is finally realized, which is easier to implement, and at the same time helps to reduce the design difficulty and cost of the second light-emitting component 20, thereby reducing the implementation difficulty and cost of the entire light source 100.

[0063] Among them, the first segmented spectrum, the second segmented spectrum, the third segmented spectrum, and the fourth segmented spectrum can be four relatively uniform spectral bands. For example, the first segmented spectrum can be a spectrum in the range of 700 nm to 721 nm, the second segmented spectrum can be a spectrum in the range of 720 nm to 741 nm, the third segmented spectrum can be a spectrum in the range of 740 nm to 761 nm, and the fourth segmented spectrum can be a spectrum in the range of 760 nm to 785 nm.

[0064] The first light-emitting element 21, the second light-emitting element 22, the third light-emitting element 23, and the fourth light-emitting element 24 form the second light-emitting component 20. The four light-emitting elements relatively uniformly supplement four parts in the range of 700 nm to 785 nm, which can reduce or avoid the need for one or several of the light-emitting elements to supplement a longer wavelength spectrum, thereby increasing the complexity and cost of the light-emitting element. This helps to reduce the complexity of each light-emitting element, thereby reducing the design difficulty and manufacturing cost of the second light-emitting component 20.

[0065] Among them, the first light-emitting element 21, the second light-emitting element 22, the third light-emitting element 23, and the fourth light-emitting element 24 can be monochromatic red light beads.

[0066] Specifically, for example, the first light-emitting element 21 can be a monochromatic red light bead with a spectrum in the range of 700 nm to 721 nm, the second light-emitting element 22 can be a monochromatic red light bead with a spectrum in the range of 720 nm to 741 nm, the third light-emitting element 23 can be a monochromatic red light bead with a spectrum in the range of 740 nm to 761 nm, and the fourth light-emitting element 24 can be a monochromatic red light bead with a spectrum in the range of 760 nm to 785 nm. In this way, through the monochromatic red light beads in four different wavelength bands, the spectrum in the range of 700 nm to 785 nm can be effectively supplemented.

[0067] Among them, the above-mentioned monochromatic red light beads can be LED beads excited by a chip in the range of 700 nm to 785 nm. Specifically, for example, they can be LED beads excited by a blue chip. The LED beads excited by a blue chip have a lower cost, which can further reduce the cost of realizing the spectrum supplement in the range of 700 nm to 785 nm and reduce the cost of the light source 100.

[0068] In the embodiment of the present application, the ratio range of the power of the first light-emitting component 10 to the power of the second light-emitting component 20 can be (1 to 20):1. In this way, better connectivity can be achieved between the spectrum of the first light-emitting component 10 and the spectrum of the second light-emitting component 20, making the overall spectrum of the light source 100 more uniform, and thus making the overall spectrum of the light source 100 have better continuity, which can further improve the overall luminous efficiency of the light source 100 and enhance the comfort of the light source 100 to the human eye.

[0069] In the embodiments of the present application, the ratio of the power of the first light-emitting element 21, the power of the second light-emitting element 22, the power of the third light-emitting element 23, and the power of the fourth light-emitting element 24 can be (1-5):(1-5):(1-5):(1-5). The first light-emitting element 21, the second light-emitting element 22, the third light-emitting element 23, and the fourth light-emitting element 24 with the power ratio within this ratio range can better achieve the spectral supplementation for the wavelength band of 700 nm to 780 nm, making the spectral continuity of the light source 100 better in this wavelength band, thereby further improving the luminous efficiency of the light source 100.

[0070] Figure 4 It is the spectral diagram of a light source provided by the embodiments of the present application.

[0071] Among them, in a possible implementation manner, the ratio of the power of the first light-emitting element 21, the power of the second light-emitting element 22, the power of the third light-emitting element 23, and the power of the fourth light-emitting element 24 can be 1:1:2:1. Refer to Figure 4 As shown, the first light-emitting element 21, the second light-emitting element 22, the third light-emitting element 23, and the fourth light-emitting element 24 with the power ratio within this ratio can achieve a relatively better supplementary effect on the spectrum within the wavelength band of 700 nm to 780 nm, making the spectral intensity higher within this wavelength band, and the spectrum within this wavelength band has relatively better continuity and uniformity, so that the overall spectrum of the light source 100 is more uniform and continuous, and the luminous efficiency of the light source 100 can be further improved.

[0072] It should be noted that the number of the first light-emitting element 21, the second light-emitting element 22, the third light-emitting element 23, and the fourth light-emitting element 24 that the second light-emitting member 20 can include can all be one, or the number of one or several of the light-emitting elements can also be two or more.

[0073] Specifically, the number of the first light-emitting element 21, the second light-emitting element 22, the third light-emitting element 23, and the fourth light-emitting element 24 included in the second light-emitting member 20 can be determined by the power of the light-emitting element itself.

[0074] For example, when the power of the first light-emitting element 21, the power of the second light-emitting element 22, the power of the third light-emitting element 23, and the power of the fourth light-emitting element 24 are all 1 w, in order to make the power ratio of the four be the above ratio, the number ratio of the first light-emitting element 21, the second light-emitting element 22, the third light-emitting element 23, and the fourth light-emitting element 24 can be 1:1:2:1.

[0075] Alternatively, for example, when the powers of the first light-emitting element 21, the second light-emitting element 22, and the fourth light-emitting element 24 are all 1 W, and the power of the third light-emitting element 23 is 2 W, the quantity ratio of the first light-emitting element 21, the second light-emitting element 22, the third light-emitting element 23, and the fourth light-emitting element 24 can be 1:1:1:1.

[0076] Figure 5 It is the spectrogram of another light source provided by the embodiment of the present application.

[0077] In another possible implementation manner, the power ratio of the first light-emitting element 21, the second light-emitting element 22, the third light-emitting element 23, and the fourth light-emitting element 24 can be 1:1:1:1. Refer to Figure 5 As shown, the first light-emitting element 21, the second light-emitting element 22, the third light-emitting element 23, and the fourth light-emitting element 24 with the power ratio being this ratio can achieve a better supplementary effect on the spectrum in the wavelength range of 700 nm to 780 nm, making the intensity of the spectrum in this wavelength range higher, so that the spectrum of the light source 100 has better continuity and uniformity, and further improving the luminous efficiency of the light source 100.

[0078] In the embodiment of the present application, the light intensities of the first light-emitting element 21, the second light-emitting element 22, the third light-emitting element 23, and the fourth light-emitting element 24 can all be greater than 0.3. Ensure that the first light-emitting element 21, the second light-emitting element 22, the third light-emitting element 23, and the fourth light-emitting element 24 have relatively high spectral intensities, so as to effectively improve the spectral intensity of the light source in the wavelength range of 700 nm to 780 nm. Ensure the supplementary effect of the first light-emitting element 21, the second light-emitting element 22, the third light-emitting element 23, and the fourth light-emitting element 24 in each segmented spectrum, further improving the overall spectral uniformity and continuity of the light source 100, and enhancing the luminous efficiency of the light source 100.

[0079] Figure 6 It is the layout schematic diagram of a first light-emitting component, the first light-emitting element, the second light-emitting element, the third light-emitting element, and the fourth light-emitting element provided by the embodiment of the present application, Figure 7 It is another layout schematic diagram of a first light-emitting component, the first light-emitting element, the second light-emitting element, the third light-emitting element, and the fourth light-emitting element provided by the embodiment of the present application.

[0080] Among them, the layout manners of the first light-emitting component 10, the first light-emitting element 21, the second light-emitting element 22, the third light-emitting element 23, and the fourth light-emitting element 24 can be various. For example, the first light-emitting component 10, the first light-emitting element 21, the second light-emitting element 22, the third light-emitting element 23, and the fourth light-emitting element 24 can be arranged in a row or a column in sequence.

[0081] Or, refer toFigure 6 As shown, the first light-emitting member 10, the first light-emitting element 21, the second light-emitting element 22, the third light-emitting element 23, and the fourth light-emitting element 24 can be evenly distributed to form a row, so that the light source 100 has a strip-shaped structure.

[0082] Or, referring to Figure 7 As shown, the first light-emitting member 10, the first light-emitting element 21, the second light-emitting element 22, the third light-emitting element 23, and the fourth light-emitting element 24 can also take one or several of them as the center, and the rest are evenly distributed around the center to form a ring.

[0083] Or, the first light-emitting member 10, the first light-emitting element 21, the second light-emitting element 22, the third light-emitting element 23, and the fourth light-emitting element 24 can also be arranged according to other regular or irregular arrangement methods. The arrangement methods of the first light-emitting member 10, the first light-emitting element 21, the second light-emitting element 22, the third light-emitting element 23, and the fourth light-emitting element 24 can be selected and set according to specific scenario requirements.
