[0073] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0074] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the utility model described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0075] To address the problems of the prior art, this utility model provides a multifunctional living room lamp. Figure 1 A structural block diagram of a living room lamp provided for an embodiment of this utility model, with reference to... Figure 1 The living room lamp includes a driver module 10 and at least one light-emitting chip 20, which are electrically connected. The maximum luminous flux of the emitted light from the living room lamp is greater than or equal to 1000 lm. The driver module 10 drives the light-emitting chip 20 to emit light, and the driver module 10 includes multiple drive levels to drive the light-emitting chip 20 to emit light of different brightness.

[0076] The light-emitting chip 20 can be a semiconductor light-emitting diode (LED) chip. The number of wavelengths, specific wavelengths, characteristic wavelengths and half-peak widths of different wavelengths, and light intensity ratios of different wavelengths can be selected as needed to form the living room lamp of this embodiment. The LED chip can be packaged to obtain the required light source. Multiple packaging methods are available, resulting in simple packaging processes, driving methods, and control methods, facilitating cost control and easily obtaining the lighting spectrum of the living room lamp. Furthermore, the size of the light-emitting chip 20 can be flexibly adjusted to reduce costs and improve reliability and lifespan. The driving module 10 provides energy to the light-emitting chip 20 to drive it to emit light. To achieve a multi-functional design, the driving module 10 can drive the luminous flux of the living room lamp to exceed 1000 lm and can divide the brightness levels, integrating multiple lamp functions such as a night light, bedside lamp, and camping lamp into one lamp. For example, the higher brightness level can function as a bedside lamp, and the lower brightness level can function as a night light. Preferably, the brightness levels are set at 1% / 50% / 100%, with multiple brightness levels between 1% and 50% serving as multiple brightness levels for the night light and multiple brightness levels between 50% and 100% serving as multiple brightness levels for the bedside lamp. Stepless dimming can also be set. In specific implementation, the design can be adjusted according to the actual situation to achieve multiple uses for one lamp.

[0077] Figure 2 A structural block diagram of another living room lamp provided in this embodiment of the present utility model is shown below. Figure 2 Optionally, the living room lamp may also include at least one of the following structures: aromatherapy or humidification structure 30, charging structure 40, digital display 50, Bluetooth speaker 60 and gas sensor 70, wherein the aromatherapy or humidification structure 30, charging structure 40, digital display 50, Bluetooth speaker 60 and gas sensor 70 may all be connected to the driver module 10.

[0078] The aromatherapy or humidification structure 30 can be set with multiple adjustable levels to achieve aromatherapy or humidification functions. Furthermore, the living room lamp can be set with a timer function, which can be used in conjunction with the timer function of the living room lamp. The charging structure 40 can have a built-in battery or a voltage conversion unit to convert AC power to DC power for wired or wireless charging of external devices such as mobile phones and tablets. The digital display 50 can display at least one of the following: current time, ambient humidity, ambient temperature, alarm time, or ambient gas indicators. Ambient humidity and ambient temperature can be monitored by the humidity sensor and temperature sensor of the living room lamp, while the current time and alarm time can be obtained from the timer unit built into the living room lamp. The specific implementation can be designed according to actual conditions. The Bluetooth speaker 60 can be used as a regular speaker or, in conjunction with the timer function of the living room lamp, can further aid in falling asleep. Combined with a wake-up mode and timed light-on function, it can help naturally wake up and stimulate human activity. The gas sensor 70 can be used to detect at least one of dust, carbon dioxide, carbon monoxide, formaldehyde, benzene, toluene, and ammonia in the environment, indicating whether the gas indicators in the environment meet the standards, thus protecting human health from the perspective of air health.

[0079] The living room lamp provided in this embodiment of the utility model can integrate multiple functions into one according to actual usage needs. It can be placed indoors or outdoors, which can greatly reduce the area required. When used outdoors, it can achieve multiple uses with one lamp, making it more convenient to use. By adding a gas detection function, it can protect human health in terms of air quality.

[0080] Figure 3 This is a schematic diagram of the structure of a light-emitting chip provided in an embodiment of the present invention, with reference to... Figure 3 Optionally, the light-emitting chip 100 includes an N-type semiconductor layer 101, a P-type semiconductor layer 104, and a first light-emitting layer 103 and a second light-emitting layer 102 disposed between the N-type semiconductor layer 101 and the P-type semiconductor layer 104. The first light-emitting layer 103 is located on the side of the second light-emitting layer 102 closer to the P-type semiconductor layer 104. The first light-emitting layer 103 generates light of at least one wavelength by electroluminescence, and the first light-emitting layer 103 may include at least one first light-emitting layer (…). Figure 3(Not shown), the light generated by the first light-emitting layer 103 excites the second light-emitting layer 102 to generate light of at least one wavelength, and the second light-emitting layer 102 may include at least one second light-emitting layer (…). Figure 3 (Not shown), each band of light contains at least one wavelength.

[0081] The light-emitting chip 100 can be a light-emitting diode chip, which can exhibit both electroluminescence (EL) and photoluminescence (PL) forms, resulting in good stability of the spectral energy distribution of the light-emitting chip 100 as the current changes. The second light-emitting layer 102, which is photoluminescent, is located between the N-type semiconductor layer 101 and the P-type semiconductor layer 104. The second light-emitting layer 102 can release stress in advance, thereby improving the external quantum efficiency of the first light-emitting layer 103. Simultaneously, the second light-emitting layer 102 itself has good crystal quality and can undergo multiple reflections and absorptions of light between the N-type semiconductor layer 101 and the P-type semiconductor layer 104, further improving its external quantum efficiency. This results in the wavelengths generated by both the first and second light-emitting layers 103 exhibiting higher external quantum efficiency (EQE) compared to traditional LEDs.

[0082] A living room lamp may include one or more light-emitting chips 100, which are multi-wavelength chips, i.e., have at least two wavelengths. The shape of the light-emitting chip 100 may be rectangular, square, circular, elliptical, triangular, rhomboid, parallelogram, or other polygonal shapes. Each light-emitting chip 100 includes an N-type semiconductor layer 101, a P-type semiconductor layer 104, a first light-emitting layer 103, and a second light-emitting layer 102. The first light-emitting layer 103 and the second light-emitting layer 102 are stacked, with the first light-emitting layer 103 located on the side of the second light-emitting layer 102 closer to the P-type semiconductor layer 104, i.e., the first light-emitting layer 103 is closer to the P-type semiconductor layer 104, and the second light-emitting layer 102 is closer to the N-type semiconductor layer 101. Holes output from the P-type semiconductor layer 104 and electrons output from the N-type semiconductor layer 101 recombine within the first light-emitting layer 103, causing the first light-emitting layer 103 to generate light of at least one wavelength in an EL manner. A hole isolation region exists between the first light-emitting layer 103 and the second light-emitting layer 102, preventing holes output from the P-type semiconductor layer 104 from reaching the second light-emitting layer 102, thus preventing the second light-emitting layer 102 from emitting light. For example, the total thickness of the electroluminescent layer is greater than or equal to the hole diffusion length, forming the hole isolation region; or a hole isolation layer exists between the electroluminescent layer and the photoluminescent layer, with the total thickness of the hole isolation layer and the electroluminescent layer greater than or equal to the hole diffusion length. Light of a first wavelength generated by the first light-emitting layer 103 is transmitted to the second light-emitting layer 102, exciting the second light-emitting layer 102, causing the second light-emitting layer 102 to generate light of at least one wavelength in a photoluminescent (PL) manner.

[0083] It is understandable that when the first light-emitting layer 103 generates light of one wavelength, it only exhibits electroluminescence as its light-emitting mechanism. When the first light-emitting layer 103 generates light of at least two wavelengths, the smallest wavelength will excite photoluminescence of the material with a larger wavelength, thus enabling the first light-emitting layer 103 to exhibit both electroluminescence and photoluminescence mechanisms. Holes within the P-type semiconductor layer 104 are difficult to transport to the second light-emitting layer 102, therefore the second light-emitting layer 102 only exhibits photoluminescence as its light-emitting mechanism.

[0084] Thus, the light-emitting chip 100 exhibits both electroluminescence and photoluminescence, resulting in good stability of the spectral energy distribution of the living room lamp as the current changes. The second light-emitting layer 102, which is photoluminescent, is located between the N-type semiconductor layer 101 and the P-type semiconductor layer 104. The second light-emitting layer 102 can release stress in advance, thereby improving the external quantum efficiency of the first light-emitting layer 103. At the same time, the second light-emitting layer 102 itself has good crystal quality and can undergo multiple reflections and absorptions between the N-type semiconductor layer 101 and the P-type semiconductor layer 104, which also improves the external quantum efficiency of the second light-emitting layer 102. As a result, the wavelengths generated by both the first light-emitting layer 103 and the second light-emitting layer 102 can have higher external quantum efficiencies than those of traditional LEDs.

[0085] Each wavelength band can contain multiple wavelengths, with the number of wavelengths being greater than or equal to 1 and less than or equal to 10. The number of wavelengths in different wavelength bands can be equal or unequal. The wavelength bands generated by the first light-emitting layer 103 and the second light-emitting layer 102 can be the same or different. Multiple wavelengths can be obtained through a single light-emitting chip, and the characteristic wavelengths and half-peak widths of multiple different wavelengths can be precisely tuned, as can the intensity ratios of different wavelengths.

[0086] In this way, the number of wavelengths, specific wavelengths, characteristic wavelengths and half-peak widths of different wavelengths, as well as the light intensity ratios of different wavelengths, can be selected according to needs to achieve various lighting modes. This allows the spectral design of living room lamps to break through the limitations of traditional LED chips. Furthermore, using this multi-wavelength LED chip that combines electroluminescence and photoluminescence simplifies the driving method, packaging process, and control method, making it easier to control costs and readily obtain a full-spectrum lighting spectrum. In addition, the size of the multi-wavelength chip and the LED chip group can be flexibly adjusted, reducing costs and improving reliability and lifespan.

[0087] Optionally, the living room light also includes a timer unit, which includes a timer-on unit and / or a timer-off unit. The timer-on unit controls the living room light to turn on in different modes during different preset time periods; the timer-off unit controls the living room light to turn off during preset time periods. The timer-on unit and / or timer-off unit enable the living room light to achieve simple and convenient intelligent control of multiple modes.

[0088] For example, living room lights can be set to turn on during certain times of the day and off during others. Optionally, the modes include a sleep mode, a wake-up mode, and a work mode. These modes define and differentiate three daily lighting patterns. For instance, in sleep mode, it is recommended to activate it after 8:00 pm to aid in falling asleep (the body's melatonin secretion typically begins after 8:00 pm); in wake-up mode, it is recommended to activate it after 6:00 am to help naturally wake up and stimulate vitality; and in work mode, it is recommended to activate it during work and study to help with efficient work and study. The living room lamp can also be equipped with a brightness adjustment function, with a maximum luminous flux of over 1000lm. It can be set with stepless dimming or multiple adjustable levels, such as 1% to 50% for a night light function and 50% to 100% for a bedside lamp function, and the stepless dimming or multiple adjustable levels can better match the user's needs. It can also be set with a timer function. Preferably, it can be paired with a Bluetooth speaker with voice or music wake-up function. The timer function can be combined with a wake-up mode to help users wake up naturally and stimulate their vitality. It can also be set with a timer function. Preferably, it can be paired with a Bluetooth speaker to select sleep-aid music, or with an aromatherapy diffuser to provide sleep-aid aromatherapy. The timer function can be combined with a sleep mode to help users fall asleep and greatly reduce the risk of insomnia. Other functions can also be set, such as voice control, touch switch, mechanical master switch, APP control, human body sensor to turn on / off, and ambient light sensor to turn on / off.

[0089] In sleep mode, the light emitted by the living room lamp includes and emphasizes the green band, excludes the cyan band, or includes cyan with an energy less than one-tenth that of the green band, and also includes at least one of the blue and purple bands, and at least one of the red and yellow bands; when the emitted light includes the blue band, the hazard level of the blue band is better than RG0 (i.e., no danger), achieving the most reliable effect of preventing blue light damage; in wakefulness mode, the light emitted by the living room lamp includes and emphasizes the cyan band; also includes the yellow band, and / or, also includes the green and red bands; in work mode, the light emitted by the living room lamp includes and emphasizes the cyan and green bands, and also includes at least one of the yellow and red bands.

[0090] In sleep mode, the living room lamp's lighting scheme primarily enhances melatonin secretion. Its spectrum must emphasize green light, excluding cyan light, and must also include at least one of blue (420nm~480nm) and violet (400nm~420nm) light, as well as at least one of red and yellow light. Other wavelengths can be added as needed. In wakefulness mode, the living room lamp's lighting scheme primarily stimulates vitality. Its spectrum must emphasize cyan light, containing little or no green light, and must also include at least yellow light, or one of (red + green). Other wavelengths can be added as needed. In work mode, the living room lamp enhances alertness and reduces visual fatigue. Its spectrum must emphasize green and cyan light, and must also include at least one of yellow and red light. Other wavelengths can be added as needed.

[0091] Continue to refer to Figure 3 As shown, the first light-emitting layer 103 generates light in one wavelength band, which is the blue band. This wavelength band includes one wavelength. The second light-emitting layer 102 generates light in two wavelength bands: a blue band and a yellow band. One of the wavelength bands is the same as the one generated by the first light-emitting layer 103, and this wavelength band includes one wavelength. The other wavelength band is different from the one generated by the first light-emitting layer 103, and this wavelength band also includes one wavelength. Obtaining multiple wavelengths through a single light-emitting chip can improve the continuity of the spectrum.

[0092] In this way, the number of wavelengths of the light-emitting chip 100, the specific wavelength, the peak wavelength and half-peak width of different wavelengths, and the light intensity ratio of different wavelengths can be selected as needed to achieve a variety of lighting methods. This allows the spectral design of each lighting to break through the limitations of traditional light-emitting diode chips, fully consider the rhythmic effects under light and dark vision, and achieve ultra-low blue light and ultra-high luminous efficiency.

The spectrum of the light-emitting chip 100 is as follows: Figure 9 As shown.

[0096] In some preferred embodiments, the number of wavelengths in each band is greater than or equal to four to obtain a spectrum with better continuity. Furthermore, the wavelengths of light within the same band are arranged in order of magnitude, with the difference between two adjacent wavelengths being greater than or equal to 5 nm and less than or equal to 60 nm. For example, in the 420 nm to 480 nm band, the difference between two adjacent wavelengths is 15 nm.

[0097] Optionally, the light emitted by the first light-emitting layer 103 corresponds to at least one of the following wavelengths: violet, blue, cyan, or green. The light emitted by the second light-emitting layer 102 corresponds to at least one of the following second wavelengths: violet, blue, cyan, green, yellow, red, or infrared. Furthermore, at least one wavelength of the light emitted by the first light-emitting layer 103 is smaller than all wavelengths of the light emitted by the second light-emitting layer 102. Thus, the light emitted by the first light-emitting layer 103 can excite the second light-emitting layer 102 to emit light.

[0098] In some preferred embodiments, the light emitted by the first light-emitting layer 103 corresponds to the violet and / or blue wavelength bands, meaning the electroluminescent first light-emitting layer 103 emits violet light and / or blue light. Furthermore, the light emitted by the first light-emitting layer 103 may also correspond to the cyan or green wavelength bands, meaning the electroluminescent first light-emitting layer 103, in addition to emitting violet and / or blue light, may further emit cyan and / or green light.

[0099] The wavelength ranges are as follows: violet (400nm~420nm), blue (420nm~480nm), cyan (480nm~510nm), green (510nm~565nm), yellow (565nm~590nm), red (590nm~740nm), and infrared (740nm~1.7μm).

[0100] It is understandable that light in the violet band is violet light, and its color is violet; light in the blue band is blue light, and its color is blue; light in the cyan band is cyan light, and its color is cyan; light in the green band is green light, and its color is green; light in the yellow band is yellow light, and its color is yellow; light in the red band is red light, and its color is red; and light in the infrared band is infrared radiation, and its color is colorless.

[0101] Thus, the light-emitting chip 100 can contain a total of n colors, where 1 ≤ n ≤ 7. The electroluminescence mechanism contains 'a' colors, and the photoluminescence mechanism contains 'b' colors, where 1 ≤ a ≤ 4 and 2 ≤ b ≤ 7. Here, colors correspond to wavelengths; for example, blue corresponds to the blue wavelength band, which ranges from 420 nm to 470 nm. For ease of description and representation, in the following examples, the violet wavelength band is represented by A, the blue wavelength band by B, the cyan wavelength band by C, the green wavelength band by G, the yellow wavelength band by Y, the red wavelength band by R, and the infrared wavelength band by IR.

[0102] Furthermore, the light emitted by the first light-emitting layer 103 of at least one light-emitting chip corresponds to a wavelength range including the blue and / or violet bands, meaning that the emitted light from the living room lamp also includes at least one of blue and violet light. In this way, on the one hand, the spectral continuity of the living room lamp can be improved, and on the other hand, the wavelength range of the wavelength range corresponding to the light emitted by the first light-emitting layer 103 is relatively small, which facilitates the excitation of the second light-emitting layer 102 to emit light.

[0103] In this embodiment of the invention, in sleep mode, the living room lamp's spectrum contains green light, taking into full account both light and dark vision, selecting green light that is most relaxing for the human eye under varying light and dark conditions, effectively preventing myopia or its further progression; it contains no cyan light, ensuring an extremely low M / P ratio, promoting melatonin secretion, promoting relaxation of mind and body, promoting sleep, and protecting and repairing the body's circadian rhythm. In wakefulness mode, the living room lamp's spectrum contains cyan light, ensuring an extremely high M / P ratio, inhibiting melatonin secretion, stimulating human vitality for a long time, and promoting improved learning and work efficiency; the lighting source contains little or no green light. In work mode, when the living room lamp's spectrum contains both cyan and green light, it can simultaneously consider eye protection and an extremely high M / P ratio, promoting improved learning and work efficiency while preventing myopia.

[0104] Figures 10-12 The following are spectral diagrams of the living room lamp provided in different modes according to embodiments of this utility model. For example, in sleep mode, the living room lamp includes wavelengths in three blue bands and one green band, and its spectrum is as follows: Figure 10 As shown. For example, in wakefulness mode, the living room light includes a blue wavelength and a cyan wavelength, with a spectrum as shown... Figure 11 As shown, for example, in operating mode, the living room lamp includes three blue wavelengths, one cyan wavelength, and one green wavelength, with its spectrum as follows: Figure 12 As shown.

[0105] As one possible implementation, in sleep mode, the light emitted by the living room lamp includes and emphasizes the green wavelength, excludes the cyan wavelength, or contains cyan wavelengths with an energy less than one-tenth the energy of the green wavelength, and also includes at least one of the blue and purple wavelengths, as well as at least one of the red and yellow wavelengths, to achieve sleep mode lighting. The living room lamp contains green light, taking into full account both light and dark vision, selecting green light that is most relaxing for the human eye under varying light and dark conditions, effectively preventing myopia or its further progression; it contains little or no cyan light, ensuring an extremely low M / P ratio, promoting melatonin secretion, promoting relaxation of body and mind, promoting sleep, and protecting and repairing the body's circadian rhythm.

[0106] When the light emitted by a living room lamp includes the blue wavelength, the hazard level of the blue wavelength is better than RG0 (i.e., no danger), achieving the most reliable effect in preventing blue light damage. The light emitted by the living room lamp has low blue light and high green light, meaning high green light energy and low or even no blue light energy, which can reduce blue light damage and eye fatigue. The hazard level assessment standards are the national photobiological safety standards IEC62471 and GB / T 20145.

[0107] In some possible implementations, the light emitted by the living room lamp corresponds to the green, violet, and yellow wavelengths, but excludes the cyan and blue wavelengths. That is, the wavelength range emitted by the living room lamp is in the form Ax+Gy+Yz, where x, y, and z are the number of wavelengths within the corresponding wavelength range, each with a value greater than or equal to 1. Thus, the lighting source includes green, violet, and yellow light, but excludes cyan and blue light, resulting in a blue-light-free spectrum.

[0108] In other possible implementations, the light emitted by the living room lamp corresponds to the green, blue, yellow, and red wavelengths, but excludes the cyan wavelength. That is, the wavelength range emitted by the living room lamp is in the form Bx+Gy+Yz+Rm, where m is the number of wavelengths within the corresponding wavelength range, with a value greater than or equal to 1. In this way, the lighting source includes green, blue, yellow, and red light, but excludes cyan and blue light, resulting in a spectrum with low blue light emission and high luminous efficacy.

[0109] It is understandable that the light emitted by a living room lamp can correspond to the following wavelengths: Bx+Gy+Rz, Bx+Gy+Yz, Bx+Gy+Rz+IRm, Bx+Gy+Yz+IRm, Bx+Gy+Yz+Rm+IRn, Ax+Gy+Rz, Ax+Gy+Yz, Ax+Gy+Yz+Rm, Ax+Gy+Rz+IRm, Ax+Gy+Yz+IRm, Ax+Gy+Yz+Rm+IRn, Ax+By+Gz+Rm, Ax+By+Gz+Ym, Ax+By+Gz+Ym+Rn, Ax+By+Gz+Rm+IRn, Ax+By+Gz+Ym+IRn, Ax+By+Gz+Ym+Rn+IRk, etc. Where n and k are the number of wavelengths in the corresponding band, and their values ​​are greater than or equal to 1.

[0110] It should be noted that in the above implementation, the number of wavelengths of blue light produced by the living room lamp can be less than or equal to 1, meaning the lighting source contains little or no blue light, forming a non-full spectrum. Alternatively, the number of wavelengths of blue light produced by the living room lamp can be greater than or equal to 2, thus enabling the living room lamp to form a full-spectrum light source with a continuous spectrum, closer to natural light (reflected and scattered sunlight in nature).

[0111] Optionally, in sleep mode, the ratio of the light power of the green wavelength to the sum of the blue and violet wavelengths is greater than 3, creating low-blue-light or blue-light-free illumination. Understandably, when the light emitted by the living room lamp corresponds to a wavelength including the blue band but excluding the violet band, the ratio of the light power of the green wavelength to the sum of the blue and violet wavelengths is the same as the ratio of the light power of the green wavelength to the light power of the blue wavelength, i.e., G:B greater than 3. When the light emitted by the living room lamp corresponds to a wavelength including the violet band but excluding the blue band, the ratio of the light power of the green wavelength to the sum of the blue and violet wavelengths is the same as the ratio of the light power of the green wavelength to the light power of the violet wavelength, i.e., G:A greater than 3. When the light emitted by the living room lamp corresponds to a wavelength including both the blue and violet bands, the ratio of the light power of the green wavelength to the sum of the blue and violet wavelengths, i.e., G:(A+B), is greater than 3.

[0112] The ratio of the light power of the green band to the light power of the red / yellow band is greater than 1. Specifically, when the light emitted by a living room lamp includes the red band, the ratio of the light power of the green band to the red band is greater than 1. When the light emitted by a living room lamp includes the yellow band, the ratio of the light power of the green band to the yellow band is greater than 1. When the light emitted by a living room lamp includes both the red and yellow bands, the ratio of the light power of the green band to the red band is greater than 1, or the ratio of the light power of the green band to the yellow band is greater than 1.

[0113] In wakefulness mode, the light emitted by the living room lamp includes, and emphasizes, the cyan wavelength; it also includes the yellow wavelength, and / or, the green and red wavelengths, forming the lighting pattern for wakefulness mode. The living room lamp contains cyan light, ensuring a very high M / P ratio, inhibiting melatonin secretion, and can stimulate human vitality for a long time, promoting improved learning and work efficiency. The living room lamp contains little or no green light. Thus, the light emitted by the living room lamp has the characteristics of low blue light and high cyan light, that is, high cyan light energy and low or even no blue light energy, which can reduce blue light damage and improve alertness.

[0114] In one possible example, the light emitted by the living room lamp corresponds to the cyan and yellow wavelengths, and the wavelength range is Cx+Yy. The light source contains cyan and yellow light but no blue light. In other possible examples, the light emitted by the living room lamp corresponds to the cyan, green, and red wavelengths, and the ratio of the light power of the cyan wavelength to the light power of the green wavelength is less than or equal to 0.1. The wavelength range is Cx+Yy+Rz (no blue light).

[0115] Optionally, the light emitted by the living room lamp can also include other wavelengths as needed. For example, the wavelengths corresponding to the light emitted by the living room lamp may include at least one of the infrared and blue wavelengths to improve spectral continuity. For example, the wavelengths emitted by the living room lamp may be in the form of Bx+Cy+Yz (low blue light), or in the form of Bx+Cy+Yz+Gm+Rn+IRk, etc.

[0116] In the awakening mode, the ratio of light power between cyan and yellow wavelengths is greater than 1, i.e., C:Y is greater than 1. Alternatively, the ratio of light power between cyan and green / red wavelengths is greater than 1.5. Specifically, when the light emitted by the living room lamp includes the green wavelength, the ratio of light power between cyan and green wavelengths is greater than 1.5, i.e., C:G is greater than 1.5. When the light emitted by the living room lamp includes the red wavelength, the ratio of light power between cyan and red wavelengths is greater than 1.5, i.e., C:R is greater than 1.5. When the light emitted by the living room lamp includes both green and red wavelengths, the ratio of light power between cyan and green wavelengths is greater than 1.5, or the ratio of light power between cyan and red wavelengths is greater than 1.5.

[0117] It should be noted that the number of wavelengths of blue light produced by a living room lamp can be less than or equal to 1, meaning that the living room lamp contains little or no blue light, forming a non-full spectrum. Alternatively, the number of wavelengths of blue light produced by a living room lamp can be greater than or equal to 2, thus forming a full-spectrum light source. The living room lamp's spectrum is continuous and closer to natural light (reflected and scattered sunlight in nature).

[0118] Optionally, in wake mode, the ratio of the light power of cyan band light to yellow band light is greater than 1; or the ratio of the light power of cyan band light to green / red band light is greater than 1.5.

[0119] In its working mode, the light emitted by the living room lamp includes, and emphasizes, the cyan and green wavelengths, and also includes at least one of the yellow and red wavelengths, forming a lighting pattern specific to the working mode. When the living room lamp contains both cyan and green light, it can simultaneously protect the eyes and achieve a very high M / P ratio, promoting improved learning and work efficiency while preventing myopia. Thus, the light emitted by the living room lamp has the characteristics of low blue light, high cyan light, and high green light—that is, high cyan light energy, high green light energy, and low or even no blue light energy—which can reduce blue light damage, increase alertness, and reduce eye fatigue.

[0120] It should be noted that the working mode contains and emphasizes the green wavelength, and also contains the yellow and / or red wavelengths. The waking mode contains little or no green wavelength. The types of light in these two lighting modes can be the same, but the ratio of light power between the cyan and green wavelengths differs. The working mode has relatively more green light, while the waking mode contains little or no green light.

[0121] In working mode, the light emitted by the living room lamp corresponds to the cyan and green wavelengths, as well as the yellow wavelength. The wavelength emitted by the living room lamp is in the form of Cx+Gy+Yz (without blue light). The living room lamp contains cyan, green and red light. The ratio of the light power of the cyan wavelength to the light power of the green wavelength is 0.1~3, that is, C:G is 0.1~3.

[0122] In other possible implementations, the light emitted by the living room lamp corresponds to the cyan and green wavelengths, and also includes yellow or red wavelengths. The wavelengths emitted by the living room lamp are in the form of Cx+Gy+Yz or Cx+Gy+Rz, and the living room lamp contains cyan, green, and yellow light or cyan, green, and red light. In operating mode, the ratio of the light power of the cyan wavelength to the light power of the yellow / red wavelength is greater than 0.7; the ratio of the light power of the green wavelength to the light power of the yellow / red wavelength is greater than 0.7.

[0123] Specifically, when the light emitted by the living room lamp includes the red wavelength, the ratio of the light power of the cyan wavelength to the red wavelength is greater than 0.7, i.e., C:R is greater than 0.7. When the light emitted by the living room lamp includes the yellow wavelength, the ratio of the light power of the cyan wavelength to the yellow wavelength is greater than 0.7, i.e., C:Y is greater than 0.7. When the light emitted by the living room lamp includes both the red and yellow wavelengths, the ratio of the light power of the cyan wavelength to the red wavelength, or the ratio of the light power of the cyan wavelength to the yellow wavelength, is greater than 0.7.

[0124] Furthermore, when the light emitted by the living room lamp corresponds to the red wavelength, the ratio of the light power of the green wavelength to that of the red wavelength is greater than 0.7, i.e., G:R is greater than 0.7. When the light emitted by the living room lamp corresponds to the yellow wavelength, the ratio of the light power of the green wavelength to that of the yellow wavelength is greater than 0.7, i.e., G:Y is greater than 0.7. When the light emitted by the living room lamp corresponds to both the red and yellow wavelengths, the ratio of the light power of the green wavelength to that of the red wavelength is greater than 0.7, or the ratio of the light power of the green wavelength to that of the yellow wavelength is greater than 0.7.

[0125] Optionally, the light emitted by the living room lamp can also include other wavelengths as needed. For example, the wavelengths corresponding to the light emitted by the living room lamp may include at least one of the infrared and blue wavelengths to improve the continuity of the living room lamp's spectrum. For example, the wavelengths emitted by the living room lamp can be in the form of Bx+Cy+Gz+Ym, Bx+Cy+Yz+Gm+Rn+IRk, etc.

[0126] It should be noted that the number of wavelengths of blue light produced by a living room lamp can be less than or equal to 1, meaning the living room lamp contains little or no blue light, forming a non-full spectrum. At least one light-emitting chip can produce a number of wavelengths of blue light greater than or equal to 2, thus enabling the living room lamp to form a full-spectrum light source, which is closer to natural light (reflected and scattered sunlight in nature).

[0127] To achieve the above three modes, living room lights can have various packaging forms, which are explained below with reference to the attached drawings.

[0128] In one possible embodiment, the living room lamp may include a light-emitting chip, the light generated by which forms the emitted light of the living room lamp. In this way, a single light-emitting chip with multiple wavelengths can obtain the required lighting light. The cost of a single multi-wavelength light-emitting chip is lower than the total cost of multiple multi-wavelength light-emitting chips, and also lower than the total cost of a traditional single-wavelength light-emitting chip and multiple phosphors, which can reduce the production cost of the living room lamp.

[0129] The light emitted by the first light-emitting layer is at least one of violet, blue, cyan, and green light, and the light emitted by the second light-emitting layer is at least one of violet, blue, cyan, green, yellow, red, and infrared light. The light emitted by the first light-emitting layer may be included within the types of light emitted by the second light-emitting layer, but with different wavelengths to improve the continuity of the corresponding light wavelengths, or it may be different from the light emitted by the second light-emitting layer to enrich the types of light.

[0130] In sleep mode, the light emitted by a light-emitting chip includes green light, excludes cyan light, and includes at least one of blue and violet light, as well as at least one of red and yellow light. For example, the light emitted by a light-emitting chip may include blue, green, and yellow light, or violet, green, and yellow light, or blue, green, and red light, or violet, blue, green, and red light, or violet, blue, green, and red light, or violet, blue, green, and yellow light, etc.

[0131] The light-emitting chip can be in the form of BxGyRz, BxGyYz, BxGyYzRm, BxGyRzIRm, BxGyYzRmIRn, AxGyRz, AxByGzYm, AxByGzYmRnIRk, etc. In specific implementation, each color contains at least one wavelength. If it is a full spectrum, it must also contain Bx, where x ≥ 2; if it is a non-full spectrum, it contains no B or contains one B wavelength (Bx, x ≤ 1). Figure 13 This is a schematic diagram of the packaging structure of a living room lamp provided in an embodiment of the present utility model, with reference to... Figure 13Taking a light-emitting chip in the form of BxGyRz as an example, the light emitted by the first light-emitting layer 103 can be in the form of Bx, and the light emitted by the second light-emitting layer 102 can be in the form of GyRz; or, Figure 14 This is a schematic diagram of another living room lamp package provided in an embodiment of the present utility model, with reference to... Figure 14 The light emitted by the first light-emitting layer 103 can be in the form of BxGy, and the light emitted by the second light-emitting layer 102 can be in the form of Rz. It is understood that the packaging structure diagram in this embodiment only shows the packaging structure of the light-emitting element and does not show other functional structures in the living room lamp.

[0132] In wakefulness mode, the light emitted by a light-emitting chip includes cyan light; it also includes yellow light, and / or, it also includes green and red light. For example, the light emitted by a light-emitting chip includes cyan and yellow light, or cyan, red and green light.

[0133] The light-emitting chip can be in the form of CxYy, CxGyRz, BxCyYz, BxCyGzRm, AxCyGzRm, etc. If it is full-spectrum, it must also contain Bx, where x ≥ 2; if it is not full-spectrum, it contains no B or contains one B wavelength (Bx, x ≤ 1). Taking the light-emitting chip as a BxCyGzRm form as an example, the light produced by the first light-emitting layer can be in the form of Bx, and the light produced by the second light-emitting layer can be in the form of CyGzRm; or, the light produced by the first light-emitting layer can be in the form of BxCy, and the light produced by the second light-emitting layer can be in the form of GzRm; or, the light produced by the first light-emitting layer can be in the form of BxCyGz, and the light produced by the second light-emitting layer can be in the form of Rm.

[0134] In operating mode, the light emitted by a light-emitting chip corresponds to wavelengths including cyan and green bands, and also includes at least one of yellow and red bands. For example, the light emitted by a light-emitting chip includes cyan and yellow light, or includes cyan, green, and red light, etc. The light-emitting chip can be in the form of CxGyYz, CxGyRz, BxCyGzYm, BxCyYzGmRnIRk, etc. If it is full-spectrum, it must also contain Bx, where x≥2; if it is not full-spectrum, it contains no B or contains one B wavelength (Bx, x≤1).

[0135] In some other possible embodiments, the living room lamp may optionally include at least two light-emitting chips, the light generated by the at least two light-emitting chips being mixed to form the emitted light of the living room lamp, and multiple light-emitting chips with multiple wavelengths obtaining the desired illumination spectrum.

[0136] In sleep mode, each light-emitting chip contains no cyan light, and all light emitted by at least two light-emitting chips includes green light, as well as at least one of blue and violet light, and at least one of red and yellow light. For example, the light emitted by each light-emitting chip does not include cyan light, and all light emitted by these chips includes blue, green, and yellow light, or includes violet, green, and yellow light; or includes blue, green, and red light; or includes violet, green, and red light, etc.

[0137] In some possible implementations, the living room lamp includes two light-emitting chips, neither of which emits cyan light. The two chips produce green light, as well as blue and / or violet light, and red and / or yellow light. For example, Figure 15 This is a schematic diagram of the packaging structure of another living room lamp provided in an embodiment of the present utility model, with reference to... Figure 15 The light-emitting chip 100a is in the BxBy form, and the light-emitting chip 100b is in the GxYy form. Alternatively, the light-emitting chip 100a may be in the AxBy form, and the light-emitting chip 100b may be in the GxRy form. Of course, these two light-emitting chips can also include light of other wavelengths; for example, the light-emitting chip 100a may be in the AxGy form, and the light-emitting chip 100b may be in the GxRyIRz form.

[0138] In some possible implementations, the living room lamp includes three light-emitting chips, none of which emit cyan light. These chips produce green light, as well as blue and / or violet light, and red and / or yellow light. For example, Figure 16 This is a schematic diagram of the packaging structure of another living room lamp provided in an embodiment of the present utility model, with reference to... Figure 16 The light-emitting chip 100a is in the AxAy form, the light-emitting chip 100b is in the GxGy form, and the light-emitting chip 100c is in the BxYy form. Of course, these three light-emitting chips can also include light in other wavelengths, for example, the light-emitting chip 100a is in the AxYy form, the light-emitting chip 100b is in the GxRy form, and the light-emitting chip 100c is in the BxIRy form.

[0139] In wakefulness mode, the light emitted by at least two light-emitting chips includes cyan light; it also includes yellow light, and / or, it also includes green and red light. For example, the light emitted by the two light-emitting chips includes cyan and yellow light, or includes cyan, red and green light.

[0140] In some possible implementations, the living room lamp includes two light-emitting chips that produce cyan light and yellow light, and / or, green and red light. For example, Figure 17 This is a schematic diagram of the packaging structure of another living room lamp provided in an embodiment of the present utility model, with reference to... Figure 17 The light-emitting chip 100a is in the GxYy form, and the light-emitting chip 100b is in the GxRy form. Of course, these two light-emitting chips can also include light in other wavelengths, for example, the light-emitting chip 100a is in the BxCy form, and the light-emitting chip 100b is in the GxRyIRz form.

[0141] In some other possible implementations, the living room light includes three light-emitting chips that produce cyan light, yellow light, and / or green and red light. For example, Figure 18 This is a schematic diagram of the packaging structure of another living room lamp provided in an embodiment of the present utility model, with reference to... Figure 18 The light-emitting chip 100a is in the GxYy form, the light-emitting chip 100b is in the GxRy form, and the light-emitting chip 100c is in the CxCy form. Of course, these three light-emitting chips can also include light in other wavelengths, for example, the light-emitting chip 100a is in the BxCy form, the light-emitting chip 100b is in the AxRy form, and the light-emitting chip 100c is in the GxIRy form.

[0142] In operating mode, the light emitted by at least two light-emitting chips includes light in the cyan and green bands, and also includes at least one of the yellow and red bands. For example, the light emitted by at least two light-emitting chips includes cyan and yellow light, or includes cyan, green and red light, etc.

[0143] In some possible implementations, the living room light includes two light-emitting chips, and the light produced by the two chips includes cyan and green light, as well as yellow and / or red light. For example, Figure 19 This is a schematic diagram of the packaging structure of another living room lamp provided in an embodiment of the present utility model, with reference to... Figure 19 The light-emitting chip 100a is in the CxCy form, and the light-emitting chip 100b is in the GxRy form. Of course, these two light-emitting chips can also include light in other wavelengths, for example, the light-emitting chip 100a is in the BxCy form, and the light-emitting chip 100b is in the GxRyIRz form.

[0144] In some other possible implementations, the living room light includes three light-emitting chips, the total light emitted by the three chips including cyan and green light, and also including yellow and / or red light. For example, Figure 20 This is a schematic diagram of the packaging structure of another living room lamp provided in an embodiment of the present utility model, with reference to... Figure 20 The light-emitting chip 100a is in the CxYy form, the light-emitting chip 100b is in the GxGy form, and the light-emitting chip 100c is in the CxRy form. Of course, these three light-emitting chips can also include light in other wavelengths, for example, the light-emitting chip 100a is in the BxCy form, the light-emitting chip 100b is in the BxGy form, and the light-emitting chip 100c is in the AxRy form.

[0145] In some other possible embodiments, the living room lamp may optionally include at least one single-wavelength chip that produces light of a single wavelength. For example, the single-wavelength chip may be in the form of R, G, B, Y, etc. The desired illumination light is obtained by mixing at least one multi-wavelength light-emitting chip and at least one single-wavelength chip.

[0146] In sleep mode, each light-emitting chip and each single-wavelength chip contains no cyan light and includes green light. Furthermore, each single / multiple light-emitting chip and each single / multiple single-wavelength chip also includes blue and / or violet light, as well as red and / or yellow light. For example, the light produced by each light-emitting chip and each single-wavelength chip does not include cyan light, and the light produced by each single / multiple light-emitting chips and each single / multiple single-wavelength chips includes blue, green, and yellow light; or includes violet, green, and yellow light; or includes blue, green, and red light; or includes violet, green, and red light, etc.

[0147] For example, Figure 21 This is a schematic diagram of the packaging structure of another living room lamp provided in an embodiment of the present utility model, with reference to... Figure 21 A single light-emitting chip and a single single-wavelength chip are packaged together. The light-emitting chip 100 is in the BxGy form, and the single-wavelength chip 100d is in the Y form. Alternatively, multiple light-emitting chips and a single single-wavelength chip can be packaged together. For example, one multi-wavelength light-emitting chip is in the BxBy form, another multi-wavelength light-emitting chip is in the GxYy form, and the single-wavelength chip is in the R form; or, for another example, one multi-wavelength light-emitting chip is in the GxRy form, another multi-wavelength light-emitting chip is in the GxYy form, and the single-wavelength chip is in the B form.

[0148] Another example is, Figure 22 This is a schematic diagram of the packaging structure of another living room lamp provided in an embodiment of the present utility model, with reference to...

Figure 23 The living room lamp includes an integrated light-emitting chip 100 and a color conversion layer 105. The color conversion layer 105 is disposed on the light-emitting side of the light-emitting chip 100.

For example, the light generated by one or more light-emitting chips and one or more single-wavelength chips includes cyan and yellow light, or includes cyan, red and green light.

[0162] For example, Figure 26 This is a schematic diagram of the packaging structure of another living room lamp provided in an embodiment of the present utility model, with reference to...

For example, one multi-wavelength light-emitting chip is in the CxCy form, another multi-wavelength light-emitting chip is in the BxBy form, and the color conversion layer 105 is in the G+R form.

[0163] As another example, a single light-emitting chip and a color conversion layer 105 are packaged together. The color conversion layer 105 generates light of at least two wavelengths. The light-emitting chip 100 is in the CxCy form, and the color conversion layer 105 is in the G+R form.

For example, the light generated by at least one light-emitting chip and color conversion layer 105 includes cyan light and yellow light, or includes cyan light, green light and red light, etc.

[0165] For example, a single light-emitting chip and a color conversion layer 105 are packaged together, the color conversion layer 105 generating light of a certain wavelength. Figure 27 This is a schematic diagram of the packaging structure of another living room lamp provided in an embodiment of the present utility model, with reference to... Figure 27 The light-emitting chip 100 is in the CxGy form, and the color conversion layer 105 is in the R form. Alternatively, multiple light-emitting chips and the color conversion layer 105 can be packaged together. The color conversion layer 105 generates light of a single wavelength; for example, one multi-wavelength light-emitting chip is in the CxYy form, another multi-wavelength light-emitting chip is in the GxGy form, and the single-wavelength chip is in the R form.

[0166] As another example, a single light-emitting chip and a color conversion layer 105 are packaged together. The color conversion layer 105 generates light of at least two wavelengths. The light-emitting chip 100 is in the CxCy form, and the color conversion layer 105 is in the G+R form.

One multi-wavelength light-emitting chip is in the GxGy form, another multi-wavelength light-emitting chip is in the CxCy form, and the color conversion layer 105 is in the Y+R form.

[0167] Of course, the light generated by at least one light-emitting chip and color conversion layer 105 in the above examples may also include light in other wavelengths, such as violet, blue, and infrared wavelengths, to improve the continuity of the illumination source spectrum. For example, in wakefulness mode, the light-emitting chip 100 is in BxCy form and the color conversion layer 105 is in G+R form; or, the light-emitting chip 100 is in BxCyGz form and the color conversion layer 105 is in R form, etc.

[0168] In other embodiments, the living room lamp further includes at least one single-wavelength chip and a color conversion layer 105. The single-wavelength chip generates light of a single wavelength, and the color conversion layer 105 is disposed on the light-emitting side of the light-emitting chip and / or the single-wavelength chip. The single-wavelength chip generates light of a single wavelength, and the color conversion layer 105 can convert and generate light of at least one wavelength. The color conversion layer 105 can be disposed on the light-emitting side of the single-wavelength chip, or on the light-emitting side of the light-emitting chip, or both. The single-wavelength chip and the color conversion layer 105 can be described with reference to the embodiments described above, and will not be repeated here.

[0169] In the first illumination method, the light generated by at least one light-emitting chip, at least one single-wavelength chip, and color conversion layer 105 does not contain cyan light, and all light includes green light, as well as blue and / or violet light, and red and / or yellow light. For example, Figure 28 This is a schematic diagram of the packaging structure of another living room lamp provided in an embodiment of the present utility model, with reference to... Figure 28 The light-emitting chip 100 is in the form of AxAy, the single-wavelength chip 100d is in the form of G, the single-wavelength chip 100e is in the form of B, and the color conversion layer 105 is in the form of R.

[0170] In wakefulness mode, the light generated by at least one light-emitting chip, at least one single-wavelength chip, and color conversion layer 105 includes cyan light; it also includes yellow light, and / or, it includes green and red light. For example, Figure 29 This is a schematic diagram of the packaging structure of another living room lamp provided in an embodiment of the present utility model, with reference to... Figure 29 The light-emitting chip 100 is in the CxCy form, the single-wavelength chip 100d is in the G form, and the color conversion layer 105 is in the R form.

[0171] In operating mode, the light generated by at least one light-emitting chip, at least one single-wavelength chip, and color conversion layer 105 includes light in the cyan and green bands, and also includes at least one of the yellow and red bands. For example, Figure 30 This is a schematic diagram of the packaging structure of another living room lamp provided in an embodiment of the present utility model, with reference to... Figure 30 The light-emitting chip 100 is in the form of CxGy, the single-wavelength chip 100d is in the form of R, and the color conversion layer 105 is in the form of Y.

[0172] Of course, the light generated by at least one light-emitting chip, at least one single-wavelength chip, and color conversion layer 105 in the above examples may also include light in other wavelengths, such as violet, blue, and infrared wavelengths, to improve the continuity of the lamp spectrum. For example, in wake mode, the light-emitting chip 100 is in BxCy form, the single-wavelength chip 100d is in G form, and the color conversion layer 105 is in R form; or, the light-emitting chip 100 is in BxCyGz form, the single-wavelength chip 100d is in G form, and the color conversion layer 105 is in R form.

[0173] In another embodiment, the first light-emitting layer in the light-emitting chip includes at least one first layer, and the second light-emitting layer includes at least two second layers. The at least one first layer and the at least two second layers are stacked sequentially, and each first layer and each second layer generates light of a certain wavelength.

[0174] The number of first layers corresponds to the number of wavelengths contained in the light emitted by the first emitting layer, with each first layer emitting one wavelength. The number of second layers corresponds to the number of wavelengths contained in the light emitted by the second emitting layer, with each second layer emitting one wavelength. The first and second layers are formed using an epitaxial process, and both can be quantum wells (QMs) or multiple quantum wells (MQWs). A quantum well includes a barrier layer and a well layer, while a multiple quantum well includes multiple cross-stacked barrier layers and multiple well layers.

[0175] In some possible examples, in the light-emitting chip, except for one first layer closest to the second layer, the sum of the thicknesses of the remaining first layers is less than the hole diffusion length, while the sum of the thicknesses of all the first layers is greater than the hole diffusion length. In this way, holes generated by the P-type semiconductor layer can reach each of the first layers, enabling each first layer to emit light. Holes generated by the P-type semiconductor layer cannot reach each of the second layers, and the second layers cannot emit light.

[0176] In other possible examples, in the light-emitting chip, a first barrier layer is disposed between adjacent first and second layers. Except for the first layer closest to the second layer, the sum of the thicknesses of the remaining first layers is less than the hole diffusion length, and the sum of the thicknesses of each first layer and the first barrier layer is greater than the hole diffusion length. In this way, holes generated by the P-type semiconductor layer can reach each first layer, enabling each first layer to emit light. Holes generated by the P-type semiconductor layer cannot penetrate the first barrier layer, meaning holes generated by the P-type semiconductor layer cannot reach each second layer, and the second layers cannot emit light. The first barrier layer can be made of gallium nitride doped with silicon.

[0177] In other possible examples, a second barrier layer is disposed between two adjacent second layers to block holes, ensuring that holes do not reach the second layer far from the P-type semiconductor. The material of the second barrier layer can be gallium nitride doped with silicon. As a preferred implementation, a second barrier layer is disposed between every two adjacent second layers, and a first barrier layer is disposed between adjacent first and second layers. This provides better hole blocking, prevents electroluminescence in the second layers, and ensures good stability of the spectral energy distribution as current changes.

[0178] The specific embodiments described above do not constitute a limitation on the scope of protection of this utility model. Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
