Detailed Description
The drawings are only for purposes of illustration and are not to be construed as limiting the invention. For a better understanding of the following embodiments, certain features of the drawings may be omitted, enlarged or reduced, and do not represent the size of an actual product; it will be understood by those skilled in the art that certain well-known structures in the drawings and descriptions thereof may be omitted.
Example 1
The embodiment is a full-spectrum desk lamp lighting method, which forms a local lighting area, can be applied to an environment with certain basic lighting, collects the current environmental color temperature as a first color temperature, and collects the current environmental spectrum as a first spectrum; the local illumination area is analyzed and obtained to keep the first color temperature, the existing first spectrum is complemented to the control parameter required by full spectrum illumination, and the desk lamp light source 100 carries out supplementary illumination on the local illumination area according to the control parameter.
The original lighting environment is fully considered, and the full-spectrum lighting in a small range is formed for the user in combination with the original lighting environment, so that the user can provide a natural lighting area for the user by improving the local range around the user in an uncontrollable environment. Effectively reducing eye fatigue and improving mental state. The first color temperature under the original illumination environment is kept unchanged in the dimming process, so that a better effect is achieved when the spectrum in the local illumination area is supplemented, and the rejection between supplementary illumination and the surrounding environment is avoided. The light fusion between the desk lamp light source 100 and the original lighting environment in the local lighting environment is promoted.
Further, in the environment lacking the light source, the full spectrum corresponding to the color temperature can be automatically acquired for illumination by actively setting the color temperature. The local illumination area at least includes the area between the user's eyes covered by the desk lamp light source 100 and the light utilization plane, such as the desktop, the collection of the first color temperature is generally arranged above the desk lamp light source 100 and is located on the back surface of the desk lamp light source 100 which is shielded, so that the ambient color temperature which is not affected by the desk lamp light source 100 is always collected in the process of collecting the first color temperature and the first spectrum. By means of the spectral curve simulation, the difference between the first spectrum and the full spectrum corresponding to the first color temperature is analyzed, a complementary spectrum required by the first spectrum to complement to the full spectrum corresponding to the first color temperature is obtained, and the parameter of the complementary spectrum output by the desk lamp light source 100 is controlled to be a part of the control parameter.
Acquiring current ambient illumination as first illumination; the control parameters include: spectral parameters and illumination parameters; the method comprises the following steps of keeping a first color temperature of a local illumination area, and completing the existing first spectrum to control parameters required by full spectrum illumination, wherein the control parameters specifically comprise the following steps: outputting an illumination parameter according to the first illumination; analyzing the difference between the first spectrum and the full spectrum corresponding to the first color temperature, simulating a complementary spectrum required for supplementing the first spectrum to the full spectrum, forming a spectrum parameter corresponding to the complementary spectrum, and controlling the desk lamp light source 100 to perform complementary illumination on the local illumination area according to the spectrum parameter and the illumination parameter. By combining the complementing spectrum with the same color temperature and the same illumination with the first spectrum, the light coordination of a local illumination area can be improved after the spectrum complementing, and the illumination effect is improved.
Further, the first illumination is collected and used as an illumination parameter for controlling the desk lamp light source 100. By means of software simulation, on the basis of consistent illumination and consistent color temperature, a complementary spectrum of a full spectrum corresponding to the complementary first spectrum to the first color temperature is obtained in a difference complementary mode, and the complementary spectrum is used as a spectrum parameter for controlling the output spectrum of the table lamp light source 100.
Presetting and storing a plurality of full spectrums with different color temperatures, wherein each full spectrum corresponds to one color temperature; extracting a full spectrum corresponding to the first color temperature as a third spectrum; and simulating a compensation spectrum required for compensating the first spectrum to the third spectrum, and forming a spectrum parameter corresponding to the compensation spectrum. The preset stored full spectrum can be called quickly when being analyzed conveniently, and a more appropriate full spectrum can be selected according to the composition of the table lamp light source 100, so that a supplement spectrum with high accuracy can be obtained more quickly.
The same color temperature has different spectrum expression forms, even the same color temperature, and all the full spectrums are different, so that the time consumption for randomly obtaining the full spectrum of the corresponding color temperature through calculation and analysis is long, and more calculations are needed. By presetting that each color temperature display of the table lamp light source 100 has a corresponding full spectrum, when the output color temperature of the table lamp light source 100 is determined, a target full spectrum, namely a third spectrum, in a local illumination area to be adjusted by the table lamp light source 100 is rapidly determined at the same time. After the existing first spectrum and the target third spectrum are determined, a complementary spectrum required by the first spectrum is calculated through analysis and simulation means and is output in the form of spectral parameters.
Simulating a completion spectrum required for completing the first spectrum to the third spectrum, specifically: and analyzing and comparing the first spectrum and the third spectrum, acquiring the band loss of the first spectrum in a spectrum curve, forming a preliminary complementing spectrum complementary with the band loss, and further correcting according to the third spectrum by simulating the effect after the preliminary complementing spectrum is combined with the first spectrum to acquire the required complementing spectrum. The required complementary spectrum can be conveniently and rapidly acquired from the angle of the complementary of the missing wave band.
Under the same color temperature illumination, the non-full spectrum is different from the full spectrum in that the sensitivity to individual light rays is low. Due to the lack of a certain waveband, certain wavelength response of the non-full spectrum is very small, a trough which is obviously different from the full spectrum is formed on a spectrum curve in a visible mode, and the waveband corresponding to the trough can reflect the absence of the waveband of the non-full spectrum. By adopting light sources with different emission wavelengths, the power required by different wave bands is simulated and supplemented, and then the light source combination and the power proportion required by complementing the first spectrum into the third spectrum are formed through the fitting of a plurality of light sources, so that the spectrum parameters required by the table lamp light source 100 are formed.
The desk lamp light source 100 acquires the illumination of the current local illumination area as a third illumination after performing supplementary illumination on the local illumination area according to the control parameters, and keeps outputting the control parameters if the third illumination is not less than 300 lx; if the third illumination is less than 300lx and the current time is detected to be within the daytime time, calling a third color temperature, wherein the third color temperature is 5000-6000K, acquiring a full spectrum corresponding to the third color temperature as a fourth spectrum, automatically generating a fourth illumination, wherein the fourth illumination is 450-inch and 500lx, outputting control parameters of the fourth spectrum and the fourth illumination, and performing supplementary illumination on a local illumination area by the desk lamp light source 100 according to the new control parameters; if the third illumination is less than 300lx and the current time is detected to be within the night time, calling a fourth color temperature, wherein the fourth color temperature is in the range of 2700K-4000K, acquiring a full spectrum corresponding to the fourth color temperature as a fifth spectrum, automatically generating a fifth illumination, wherein the fifth illumination is 350-400lx, outputting control parameters of the fifth spectrum and the fifth illumination, and performing supplementary illumination on the local illumination area by the desk lamp light source 100 according to the new control parameters.
In order to maintain the illumination effect of the local illumination area, the illumination of the local illumination area is preferably adjusted by adopting a spectrum complementing mode, but after dimming, if the local illumination area cannot be in an environment with sufficient illumination, the local illumination area is illuminated and covered by adopting a full spectrum with high color temperature and a high illumination mode, and the full spectrum with high color temperature and the high illumination mode have the significance of reducing the influence of the original environment with low illumination at present so as to ensure that the local illumination area reaches the basic condition of desk lamp illumination and reduce the illumination incoordination caused by different spectrums, color temperatures and illuminations. Meanwhile, the desk lamp light source 100 judges daytime and nighttime states according to time, and controls the states with different color temperatures, so that a user feels more comfortable in a local illumination area.
The local illumination area covered by the desk lamp light source 100 can be more harmonious in illumination through the dimming mode with the same color temperature and the same illumination, the illumination effect is better, but at the same time, the dimming mode has a certain limitation on the illumination of the desk lamp light source 100, and the illumination cannot be effectively and greatly improved. Therefore, when the original indoor illumination is low, even if the illumination is improved to a certain extent after dimming, the basic illumination required by the desk lamp illumination may still not be ensured. Further, the problem of insufficient illumination is solved by means of covering, in order to improve the illumination effect of the desk lamp and reduce the influence of the environment on the illumination effect of the desk lamp, a full spectrum with high color temperature and high illumination are adopted, for example, the output illumination of the desk lamp light source 100 in the daytime is 500lx, the color temperature is 5300K, and the full spectrum corresponding to the spectrum 5300K is a control parameter; and at night, the output illumination is 350lx, the color temperature is 4000K, the full spectrum corresponding to the spectrum 4000K is used as a control parameter, and the local illumination area is illuminated under the condition of reducing the influence of the original environment as much as possible. The different color temperature ranges are adopted in the daytime and at night, so that the adaptability of human eyes and the environment is considered, and discomfort caused by huge color temperature difference inside and outside the local illumination area is avoided.
The collection position of the first color temperature and the first spectrum is close to the output position of the table lamp light source 100 and does not interfere with each other. The collected position is close to the output position of the desk lamp light source 100, so that the color coordinates of the two are consistent or even overlapped, the effect after light ray fusion is improved, and the synthesis of the two is more coordinated.
In the process of supplementing the local illumination area to the full spectrum by the desk lamp light source 100, the full-supplement spectrum is synthesized by adopting a multi-light-source fusion mode, and since the synthesis of multiple light sources is difficult to realize the fusion of all light sources at the same point, the fusion effect of the synthesized light source is worse and the amplitude of the synthesized light source deviating from the full spectrum is larger along with the farther distance from the light source in the illumination process. The simulation effect of the spectrum can be reduced after the desk lamp light source 100 is amplified at a distance, so the collection of the first spectrum should be close to the output position of the desk lamp light source 100, and the closest position after the light beams are synthesized is measured, which is helpful for improving the feedback speed so as to obtain a better synthesis effect. Meanwhile, the light source 100 of the desk lamp is consistent with the color coordinates of the original lighting environment, which cannot be fused, and in order to make the color coordinates of the light source and the original lighting environment closer, the collecting position should be set at the output position of the indoor lighting, so that the light source and the original lighting environment can be better combined
The distance between the desk lamp light source 100 and the light plane is 300 mm and 700 mm. The light utilization within the distance can ensure the effect of the table lamp light source 100 after light fusion with the local illumination area. The closer the combined light distance of the multiple light sources is, the better the effect of the combination with the environment is, and the farther the illumination distance is, the worse the combined light effect of the table lamp light source 100 is, and the worse the spectrum completion effect in the local illumination area is, so that a certain light distance should be limited. And the light plane refers to a position observed by human eyes, such as a desktop, a book surface and the like.
Example 2
The embodiment is a full-spectrum desk lamp lighting method, which presets and stores a plurality of full spectrums with different color temperatures, and each full spectrum corresponds to one color temperature; the current illumination and color temperature values can be digitally displayed at any time; the color temperature and the input illumination are actively selected, and the illumination is 300lx-500 lx; the color temperature is 2700K-6000K; automatically calling control parameters of full spectrum and illumination corresponding to the color temperature; and outputting control parameters of full spectrum and illumination corresponding to the color temperature selected actively, and performing supplementary illumination on the local illumination area by the desk lamp light source 100 according to the new control parameters.
Through active setting, a user can quickly control the desk lamp light source 100 to output a comfortable light source in a space without environmental lighting or with little environmental lighting influence, and further can keep local area lighting under a specific color temperature and illumination. The digital display further assists the user to know the data representation of the color temperature and the illumination, so that the user can more intuitively feel the influence of the color temperature and the illumination on the table lamp light source 100, and the user can conveniently record the color temperature and the illumination which are comfortable to feel.
The active setting of colour temperature and illuminance provides the illumination of the local illumination district implementation of a free collocation for the user, through setting up desk lamp light source 100 to the environment of rising to the sun between 8 o 'clock to 9 o' clock earlier, helps promoting to eliminate fatigue, adjusts the mood. If people are placed in natural environment, the mood is relieved, and the depression is improved. Further, everybody is all different to the indoor lighting's of different illuminance sensitivity, comfort level and adaptability, and most users all lack professional optical knowledge, thereby they can't express that the illuminance that they need changes and let equipment discernment, and digital demonstration can help the user to form the directly perceived perception to colour temperature and illuminance fast, promotes to use and experiences.

By means of the spectral curve simulation, the difference between the first spectrum and the full spectrum corresponding to the first color temperature is analyzed, a complementary spectrum required by the first spectrum to complement to the full spectrum corresponding to the first color temperature is obtained, and the parameter of the complementary spectrum output by the desk lamp light source 100 is controlled to be a part of the control parameter.
Acquiring current ambient illumination as first illumination; the control parameters include: spectral parameters and illumination parameters; the method comprises the following steps of keeping a first color temperature of a local illumination area, and completing the existing first spectrum to control parameters required by full spectrum illumination, wherein the control parameters specifically comprise the following steps: outputting an illumination parameter according to the first illumination; analyzing the difference between the first spectrum and the full spectrum corresponding to the first color temperature, simulating a complementary spectrum required for supplementing the first spectrum to the full spectrum, forming a spectrum parameter corresponding to the complementary spectrum, and controlling the desk lamp light source 100 to perform complementary illumination on the local illumination area according to the spectrum parameter and the illumination parameter. By combining the complementing spectrum with the same color temperature and the same illumination with the first spectrum, the light coordination of a local illumination area can be improved after the spectrum complementing, and the illumination effect is improved.
Further, the first illumination is collected and used as an illumination parameter for controlling the desk lamp light source 100. By means of software simulation, on the basis of consistent illumination and consistent color temperature, a complementary spectrum of a full spectrum corresponding to the complementary first spectrum to the first color temperature is obtained in a difference complementary mode, and the complementary spectrum is used as a spectrum parameter for controlling the output spectrum of the table lamp light source 100.
Presetting and storing a plurality of full spectrums with different color temperatures, wherein each full spectrum corresponds to one color temperature; extracting a full spectrum corresponding to the first color temperature as a third spectrum; and simulating a compensation spectrum required for compensating the first spectrum to the third spectrum, and forming a spectrum parameter corresponding to the compensation spectrum. The preset stored full spectrum can be called quickly when being analyzed conveniently, and a more appropriate full spectrum can be selected according to the composition of the table lamp light source 100, so that a supplement spectrum with high accuracy can be obtained more quickly.
The same color temperature has different spectrum expression forms, even the same color temperature, and all the full spectrums are different, so that the time consumption for randomly obtaining the full spectrum of the corresponding color temperature through calculation and analysis is long, and more calculations are needed. By presetting that each color temperature display of the table lamp light source 100 has a corresponding full spectrum, when the output color temperature of the table lamp light source 100 is determined, a target full spectrum, namely a third spectrum, in a local illumination area to be adjusted by the table lamp light source 100 is rapidly determined at the same time. After the existing first spectrum and the target third spectrum are determined, a complementary spectrum required by the first spectrum is calculated through analysis and simulation means and is output in the form of spectral parameters.
Simulating a completion spectrum required for completing the first spectrum to the third spectrum, specifically: and analyzing and comparing the first spectrum and the third spectrum, acquiring the band loss of the first spectrum in a spectrum curve, forming a preliminary complementing spectrum complementary with the band loss, and further correcting according to the third spectrum by simulating the effect after the preliminary complementing spectrum is combined with the first spectrum to acquire the required complementing spectrum. The required complementary spectrum can be conveniently and rapidly acquired from the angle of the complementary of the missing wave band.
Under the same color temperature illumination, the non-full spectrum is different from the full spectrum in that the sensitivity to individual light rays is low. Due to the lack of a certain waveband, certain wavelength response of the non-full spectrum is very small, a trough which is obviously different from the full spectrum is formed on a spectrum curve in a visible mode, and the waveband corresponding to the trough can reflect the absence of the waveband of the non-full spectrum. By adopting light sources with different emission wavelengths, the power required by different wave bands is simulated and supplemented, and then the light source combination and the power proportion required by complementing the first spectrum into the third spectrum are formed through the fitting of a plurality of light sources, so that the spectrum parameters required by the table lamp light source 100 are formed.
The desk lamp light source 100 acquires the illumination of the current local illumination area as a third illumination after performing supplementary illumination on the local illumination area according to the control parameters, and keeps outputting the control parameters if the third illumination is not less than 300 lx; if the third illumination is less than 300lx and the current time is detected to be within the daytime time, calling a third color temperature, wherein the third color temperature is 5000-6000K, acquiring a full spectrum corresponding to the third color temperature as a fourth spectrum, automatically generating a fourth illumination, wherein the fourth illumination is 450-inch and 500lx, outputting control parameters of the fourth spectrum and the fourth illumination, and performing supplementary illumination on a local illumination area by the desk lamp light source 100 according to the new control parameters; if the third illumination is less than 300lx and the current time is detected to be within the night time, calling a fourth color temperature, wherein the fourth color temperature is in the range of 2700K-4000K, acquiring a full spectrum corresponding to the fourth color temperature as a fifth spectrum, automatically generating a fifth illumination, wherein the fifth illumination is 350-400lx, outputting control parameters of the fifth spectrum and the fifth illumination, and performing supplementary illumination on the local illumination area by the desk lamp light source 100 according to the new control parameters.
In order to maintain the illumination effect of the local illumination area, the illumination of the local illumination area is preferably adjusted by adopting a spectrum complementing mode, but after dimming, if the local illumination area cannot be in an environment with sufficient illumination, the local illumination area is illuminated and covered by adopting a full spectrum with high color temperature and a high illumination mode, and the full spectrum with high color temperature and the high illumination mode have the significance of reducing the influence of the original environment with low illumination at present so as to ensure that the local illumination area reaches the basic condition of desk lamp illumination and reduce the illumination incoordination caused by different spectrums, color temperatures and illuminations. Meanwhile, the desk lamp light source 100 judges daytime and nighttime states according to time, and controls the states with different color temperatures, so that a user feels more comfortable in a local illumination area.
The local illumination area covered by the desk lamp light source 100 can be more harmonious in illumination through the dimming mode with the same color temperature and the same illumination, the illumination effect is better, but at the same time, the dimming mode has a certain limitation on the illumination of the desk lamp light source 100, and the illumination cannot be effectively and greatly improved. Therefore, when the original indoor illumination is low, even if the illumination is improved to a certain extent after dimming, the basic illumination required by the desk lamp illumination may still not be ensured. Further, the problem of insufficient illumination is solved by means of covering, in order to improve the illumination effect of the desk lamp and reduce the influence of the environment on the illumination effect of the desk lamp, a full spectrum with high color temperature and high illumination are adopted, for example, the output illumination of the desk lamp light source 100 in the daytime is 500lx, the color temperature is 5300K, and the full spectrum corresponding to the spectrum 5300K is a control parameter; and at night, the output illumination is 350lx, the color temperature is 4000K, the full spectrum corresponding to the spectrum 4000K is used as a control parameter, and the local illumination area is illuminated under the condition of reducing the influence of the original environment as much as possible. The different color temperature ranges are adopted in the daytime and at night, so that the adaptability of human eyes and the environment is considered, and discomfort caused by huge color temperature difference inside and outside the local illumination area is avoided.
The LED chips with different emission wavelengths are output according to a certain power proportion to form a fixed spectrum under the control of the driving module. Each LED chip is used for simulating a spectrum curve in a section of range, the control of the spectrum curve of the wave band is mainly adjusted through power, a complete multi-LED chip fits the spectrum, in order to keep the inconvenience of the spectrum, the power of each LED chip is fixed according to a certain proportion, when the brightness needs to be adjusted, the power of each LED chip is increased, and the power ratio is fixed.
The collection position of the first color temperature and the first spectrum is close to the output position of the table lamp light source 100 and does not interfere with each other. The collected position is close to the output position of the desk lamp light source 100, so that the color coordinates of the two are consistent or even overlapped, the effect after light ray fusion is improved, and the synthesis of the two is more coordinated.
In the process of supplementing the local illumination area to the full spectrum by the desk lamp light source 100, the full-supplement spectrum is synthesized by adopting a multi-light-source fusion mode, and since the synthesis of multiple light sources is difficult to realize the fusion of all light sources at the same point, the fusion effect of the synthesized light source is worse and the amplitude of the synthesized light source deviating from the full spectrum is larger along with the farther distance from the light source in the illumination process. The simulation effect of the spectrum can be reduced after the desk lamp light source 100 is amplified at a distance, so the collection of the first spectrum should be close to the output position of the desk lamp light source 100, and the closest position after the light beams are synthesized is measured, which is helpful for improving the feedback speed so as to obtain a better synthesis effect. Meanwhile, the light source 100 of the desk lamp is consistent with the color coordinates of the original lighting environment, which cannot be fused, and in order to make the color coordinates of the light source and the original lighting environment closer, the collecting position should be set at the output position of the indoor lighting, so that the light source and the original lighting environment can be better combined
The distance between the desk lamp light source 100 and the light plane is 300 mm and 700 mm. The light utilization within the distance can ensure the effect of the table lamp light source 100 after light fusion with the local illumination area. The closer the combined light distance of the multiple light sources is, the better the effect of the combination with the environment is, and the farther the illumination distance is, the worse the combined light effect of the table lamp light source 100 is, and the worse the spectrum completion effect in the local illumination area is, so that a certain light distance should be limited. And the light plane refers to a position observed by human eyes, such as a desktop, a book surface and the like.
