Description

Technical Field

[0001] The present disclosure relates to the field of lamp lighting, and in particular to a lighting device with adjustable color temperature and a dynamic lighting system based in an exhibition hall. Background Art

[0002] Exhibits are displayed in museums, galleries and other exhibition halls. In order to form a certain illumination ratio between the exhibits and the surrounding environment, it is usually necessary to use lamps with smaller lamp shells and smaller light beam angles to illuminate the exhibits. While focusing on the exhibits, the lamps also ensure the concealment of the lamps to weaken the presence of the lamps. If the beam angle is large, the light will be uniform and the exhibits cannot be highlighted. In addition, in order to enhance the fun and visual perception of the exhibits, the lamps should also have the function of adjusting the color temperature. In the prior art, lamps with variable color temperature generally encapsulate two or more groups of chips with different color temperatures in the light source, and the color temperature change is achieved by adjusting the current ratio of each chip.

[0003] For example, a Chinese patent with application number CN202022331234.8 discloses a stepless color temperature adjustment light source and lamp, the light source including a substrate, a crystal bonding area is provided on the substrate, a first fixed platform and a second fixed platform are alternately provided in the crystal bonding area, a first circuit board is provided on the first fixed platform, a blue light chipset is provided on the first circuit board, the blue light chipset is covered with a first fluorescent glue layer, a transparent glue layer and a second fluorescent glue layer from bottom to top in sequence; a second circuit board is provided on the second fixed platform, a red light chipset is provided on the second circuit board, and the red light chipset is located in the transparent glue layer.

[0004] However, the structural design of the above-mentioned lamp has the following problems during use:

[0005] The above-mentioned lamp achieves color temperature change by arranging a blue light chip group and a red light chip group on the light source and adjusting the current ratio of the blue light chip group and the red light chip group. However, according to the principle of collimation optics, the beam angle is proportional to the effective light-emitting surface diameter of the light source and the diameter of the lamp lens. While ensuring that the lens diameter remains unchanged, arranging two groups of chips on the light source will inevitably increase the effective light-emitting surface diameter of the light source, thereby increasing the beam angle of the lamp and failing to meet the effect of key lighting.

[0006] In summary, there is an urgent need for a lighting device with a small lamp body, a small beam angle and adjustable color temperature. Utility Model Content

[0007] The purpose of the present invention is to overcome the deficiencies in the prior art and to provide a lighting device with a small lamp body, a small beam angle and adjustable color temperature, and a dynamic lighting system based in an exhibition hall.

[0008] The purpose of this disclosure is achieved through the following technical solutions:

[0009] A lighting device with adjustable color temperature comprises a power supply module, a dynamic color temperature control component and a wire, wherein the power supply module is electrically connected to the dynamic color temperature control component through the wire.

[0010] The lighting device also includes a lamp module, which includes a first monochromatic temperature light emitting component and a second monochromatic temperature light emitting component, the first monochromatic temperature light emitting component and the second monochromatic temperature light emitting component are electrically connected to the dynamic color temperature control component through the wire, respectively, the first monochromatic temperature light emitting component is provided with a first chip, the second monochromatic temperature light emitting component is provided with a second chip, and the color temperature value of the first chip is set differently from the color temperature value of the second chip.

[0011] In one embodiment, the first monochromatic color temperature light emitting component includes a first shell, a first light source unit and a first lens, the first light source unit and the first lens are installed inside the first shell, the first lens is located on the light emitting side of the first light source unit, and the first chip is electrically connected to the first light source unit and the dynamic color temperature control component respectively.

[0012] In one embodiment, the second monochromatic color temperature light emitting element includes a second shell, a second light source unit and a second lens, the second light source unit and the second lens are installed inside the second shell, the second lens is located on the light emitting side of the second light source unit, and the second chip is electrically connected to the second light source unit and the dynamic color temperature control element respectively.

[0013] In one embodiment, the color temperature of the first chip is 1000K-10000K; and / or,

[0014] The color temperature value of the second chip is 1000K-10000K.

[0015] In one of the embodiments, the beam angle of the first monochromatic temperature-emitting element is 3°-10°.

[0016] In one of the embodiments, the beam angle of the second monochromatic temperature-sensitive light emitting element is 3°-10°.

[0017] In one embodiment, the number of the first single-color warm-light emitting components and the number of the second single-color warm-light emitting components are the same or different.

[0019] In one embodiment, there are multiple lamp modules, and the multiple lamp modules are electrically connected to the dynamic color temperature control component through the wires respectively, and the multiple lamp modules are arranged in intervals in the display cabinet.

[0020] Compared with the prior art, the present invention has at least the following advantages:

[0021] In the above-mentioned lighting device with adjustable color temperature, the power supply module, the dynamic color temperature control component, the first monochromatic temperature light-emitting component and the second monochromatic temperature light-emitting component are electrically connected through wires respectively, the power supply module outputs a voltage flowing through the dynamic color temperature control component, and the dynamic color temperature control component outputs two groups of currents with different ratios to the first chip and the second chip respectively, so that the first monochromatic temperature light-emitting component and the second monochromatic temperature light-emitting component emit different brightnesses, and because the color temperature value of the first chip is set differently from the color temperature value of the second chip, that is, the color temperature of the light emitted by the first monochromatic temperature light-emitting component and the second monochromatic temperature light-emitting component is inconsistent, the two groups of light with different color temperatures are mixed to emit the final required color temperature light, and the brightness ratio of the two groups of light affects the color temperature of the final light, and the color temperature of the mixed light can be adjusted according to the brightness ratio of the first monochromatic temperature light-emitting component and the second monochromatic temperature light-emitting component. Furthermore, since the first monochromatic temperature-controlled light-emitting component and the second monochromatic temperature-controlled light-emitting component are each provided with only one chip, compared with the structure in which two or more groups of chips are provided inside the lamp of the traditional technology, the lamp body of the light-emitting component of the present application is smaller in volume, and the light-emitting surface diameter of the light source is smaller, thereby making the beam angle of the light-emitting component smaller.

[0026] In order to facilitate the understanding of the present disclosure, the present disclosure will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present disclosure are given in the drawings. However, the present disclosure can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present disclosure more thoroughly and comprehensively understood.

[0027] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present disclosure. The terms used herein in the specification of the present disclosure are only for the purpose of describing specific embodiments and are not intended to limit the present disclosure. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0029] The present disclosure provides a lighting device with adjustable color temperature, comprising a power supply module, a dynamic color temperature control component, a wire and a lamp module, wherein the power supply module is electrically connected to the dynamic color temperature control component through the wire, and the lamp module comprises a first monochromatic temperature light emitting component and a second monochromatic temperature light emitting component, wherein the first monochromatic temperature light emitting component and the second monochromatic temperature light emitting component are electrically connected to the dynamic color temperature control component through the wire, respectively, the first monochromatic temperature light emitting component is provided with a first chip, and the second monochromatic temperature light emitting component is provided with a second chip, and the color temperature value of the first chip is set differently from the color temperature value of the second chip.

[0030] In the above-mentioned lighting device with adjustable color temperature, the power supply module, the dynamic color temperature control component, the first monochromatic temperature light-emitting component and the second monochromatic temperature light-emitting component are electrically connected through wires respectively, the power supply module outputs a voltage flowing through the dynamic color temperature control component, and the dynamic color temperature control component outputs two groups of currents with different ratios to the first chip and the second chip respectively, so that the first monochromatic temperature light-emitting component and the second monochromatic temperature light-emitting component emit different brightnesses, and because the color temperature value of the first chip is set differently from the color temperature value of the second chip, that is, the color temperature of the light emitted by the first monochromatic temperature light-emitting component and the second monochromatic temperature light-emitting component is inconsistent, the two groups of light with different color temperatures are mixed to emit the final required color temperature light, and the brightness ratio of the two groups of light affects the color temperature of the final light, and the color temperature of the mixed light can be adjusted according to the brightness ratio of the first monochromatic temperature light-emitting component and the second monochromatic temperature light-emitting component. Furthermore, since the first monochromatic temperature-controlled light-emitting component and the second monochromatic temperature-controlled light-emitting component are each provided with only one chip, compared with the structure in which two or more groups of chips are provided inside the lamp of the traditional technology, the lamp body of the light-emitting component of the present application is smaller in volume, and the light-emitting surface diameter of the light source is smaller, thereby making the beam angle of the light-emitting component smaller.

[0031] In order to better understand the technical solutions and beneficial effects of the present invention, the present invention is further described in detail below in conjunction with specific embodiments:

[0032] like Figures 1 to 3 As shown, an illumination device 10 with adjustable color temperature in one embodiment includes a power supply module 100, a dynamic color temperature control component 200, a wire 300 and a lamp module 400, wherein the power supply module 100 is electrically connected to the dynamic color temperature control component 200 via the wire 300, and the lamp module 400 includes a first monochromatic temperature light emitting component 410 and a second monochromatic temperature light emitting component 420, wherein the first monochromatic temperature light emitting component 410 and the second monochromatic temperature light emitting component 420 are electrically connected to the dynamic color temperature control component 200 via the wire 300, respectively, and the first monochromatic temperature light emitting component 410 is provided with a first chip 411, and the second monochromatic temperature light emitting component 420 is provided with a second chip 421, and the color temperature value of the first chip 411 is set differently from the color temperature value of the second chip 421.

[0033] In this embodiment, the number of wires 300 is multiple, and the power supply module 100, the dynamic color temperature control component 200, the first single-color temperature light-emitting component 410 and the second single-color temperature light-emitting component 420 are electrically connected through the wires 300. When the dynamic color temperature control component 200 receives an external instruction, the power supply module 100 outputs a DC voltage to the dynamic color temperature control component 200. At this time, the dynamic color temperature control component 200 outputs two sets of currents with different ratios to the first single-color temperature light-emitting component 410 and the second single-color temperature light-emitting component 420, respectively, so that the first single-color temperature light-emitting component 410 and the second single-color temperature light-emitting component 420 emit different brightness. Further, since the color temperature values ​​of the first single-color temperature light-emitting component 410 and the second single-color temperature light-emitting component 420 are set differently, the color temperatures of the light emitted by the first single-color temperature light-emitting component 410 and the second single-color temperature light-emitting component 420 are inconsistent, and the light emitted after the two different color temperature lights are mixed is the final required color temperature light.

[0034] Furthermore, since brightness is associated with color temperature, when the ratio of the two sets of currents output by the dynamic color temperature control component 200 changes, the brightness of the first single-color temperature light-emitting component 410 and the second single-color temperature light-emitting component 420 changes accordingly, and the brightness ratio of the first single-color temperature light-emitting component 410 and the second single-color temperature light-emitting component 420 affects the color temperature value of the mixed light. For example, when the brightness of the first single-color temperature light-emitting component 410 is brighter, the color temperature value of the mixed light tends to the color temperature change of the first single-color temperature light-emitting component 410. For example, when the brightness of the second single-color temperature light-emitting component 420 is brighter, the color temperature value of the mixed light tends to the color temperature change of the second single-color temperature light-emitting component 420. Specifically, the color temperature value of the first monochromatic temperature light emitting element 410 is set to 3000K, and the color temperature value of the second monochromatic temperature light emitting element 420 is set to 4000K. Through the pre-set brightness amplitude and brightness ratio setting, the brightness of the first monochromatic temperature light emitting element 410 and the second monochromatic temperature light emitting element 420 is adjusted from 0% to 100%. When the first monochromatic temperature light emitting element 410 is not bright, the color temperature value of the mixed light is 4000K. When the second monochromatic temperature light emitting element 420 is not bright, the color temperature value of the mixed light is 3000K. That is, the color temperature value variation range of the mixed light is 3000K-4000K, and the color temperature variation range of the mixed light depends on the color temperature values ​​of the first monochromatic temperature light emitting element 410 and the second monochromatic temperature light emitting element 420.

[0035] Furthermore, since the first monochromatic temperature-sensitive light emitting component 410 and the second monochromatic temperature-sensitive light emitting component 420 are each provided with only one chip, the lamp body volume of the first monochromatic temperature-sensitive light emitting component 410 and the second monochromatic temperature-sensitive light emitting component 420 is smaller. Compared with the structure in which two or more groups of chips are provided inside the lamp in the conventional technology, the diameter of the light source light emitting surface of the first monochromatic temperature-sensitive light emitting component 410 and the second monochromatic temperature-sensitive light emitting component 420 of the present application is smaller. Since the diameter of the light source light emitting surface is proportional to the beam angle, the beam angle is also smaller, which is more suitable for use in application scenarios such as museums and galleries where the exhibit 10a needs to be highlighted with lighting effects.

[0036] It should be noted that the method in which the dynamic color temperature control component 200 controls the brightness changes of the first monochromatic color temperature light-emitting component 410 and the second monochromatic color temperature light-emitting component 420 belongs to the prior art and is not within the scope of protection of this application. This application only protects the positional relationship and connection relationship between the components in the above-mentioned lighting device.

[0037] In the above-mentioned lighting device 10 with adjustable color temperature, the power supply module 100, the dynamic color temperature control component 200, the first monochromatic temperature light-emitting component 410 and the second monochromatic temperature light-emitting component 420 are electrically connected through the wire 300 respectively, the power supply module 100 outputs a voltage flowing through the dynamic color temperature control component 200, and the dynamic color temperature control component 200 outputs two groups of currents with different ratios to the first chip 411 and the second chip 421 respectively, so that the first monochromatic temperature light-emitting component 410 and the second monochromatic temperature light-emitting component 420 emit different brightnesses, and because the color temperature value of the first chip 411 and the color temperature value of the second chip 421 are set differently, that is, the color temperature of the light emitted by the first monochromatic temperature light-emitting component 410 and the second monochromatic temperature light-emitting component 420 is inconsistent, and the two groups of light with different color temperatures are mixed to emit the final required color temperature light, and the brightness ratio of the two groups of light affects the color temperature of the final light, and the color temperature of the mixed light can be adjusted according to the brightness ratio of the first monochromatic temperature light-emitting component 410 and the second monochromatic temperature light-emitting component 420. Furthermore, since the first monochromatic temperature-controlled light emitting component 410 and the second monochromatic temperature-controlled light emitting component 420 are each provided with only one chip, compared with the structure in which two or more groups of chips are provided inside the lamp of the traditional technology, the lamp body of the light emitting component of the present application is smaller in volume, and the light emitting surface diameter of the light source is smaller, thereby making the beam angle of the light emitting component smaller.

[0038] like Figure 2 As shown, in one embodiment, the first monochromatic color temperature light emitting element 410 includes a first housing 412, a first light source unit 413 and a first lens 414. The first light source unit 413 and the first lens 414 are installed inside the first housing 412. The first lens 414 is located at the light emitting side of the first light source unit 413. The first chip 411 is electrically connected to the first light source unit 413 and the dynamic color temperature control element 200 respectively. In this embodiment, when current flows through the first chip 411 and the first light source unit 413, the first chip 411 causes the first light source unit 413 to emit light of a corresponding color temperature value. After the light passes through the optical effect of the first lens 414, the light is more concentrated to achieve the effect of accent lighting.

[0039] like Figure 3As shown, in one embodiment, the second monochromatic color temperature light emitting element 420 includes a second housing 422, a second light source unit 423 and a second lens 424. The second light source unit 423 and the second lens 424 are installed inside the second housing 422. The second lens 424 is located at the light emitting side of the second light source unit 423. The second chip 421 is electrically connected to the second light source unit 423 and the dynamic color temperature control element 200, respectively. In this embodiment, when current flows through the second chip 421 and the second light source unit 423, the second chip 421 causes the second light source unit 423 to emit light of a corresponding color temperature value. After the light passes through the optical effect of the second lens 424, the light is more concentrated to achieve the effect of accent lighting.

[0040] In one embodiment, the color temperature value of the first chip 411 is 1000K-10000K; the color temperature value of the second chip 421 is 1000K-10000K. In this embodiment, the color temperature values ​​of the first chip 411 and the second chip 421 are inconsistent, that is, the color temperature value of the first chip 411 is lower, and the color temperature value of the second chip 421 is higher. For example, the color temperature value of the first chip 411 is 1000K, and the color temperature value of the second chip 421 is 4000K, so that the color temperature value of the light after the first single-color temperature light-emitting element 410 and the second single-color temperature light-emitting element 420 are mixed has a fluctuation range of 1000K-4000K. Of course, in other embodiments, the color temperature value of the first chip 411 can be 2000K, and the color temperature value of the second chip 421 can be 3000K, then the color temperature value of the light after the first single-color temperature light-emitting element 410 and the second single-color temperature light-emitting element 420 are mixed has a fluctuation range of 2000K-3000K.

[0041] In one of the embodiments, the beam angle of the first monochromatic temperature-sensitive light emitting element 410 is 3°-10°, so that the first monochromatic temperature-sensitive light emitting element 410 can play a key lighting effect and is more suitable for exhibition hall scene lighting.

[0042] In one embodiment, the beam angle of the second monochromatic temperature-sensitive light emitting element 420 is 3°-10°, so that the second monochromatic temperature-sensitive light emitting element 420 can play a key lighting effect and is more suitable for exhibition hall scene lighting.

[0043] In one embodiment, the number of the first monochromatic temperature-emitting light emitting element 410 and the number of the second monochromatic temperature-emitting light emitting element 420 are the same or different. It can be understood that the number of the first monochromatic temperature-emitting light emitting element 410 can be single or multiple, and the number of the second monochromatic temperature-emitting light emitting element 420 can be single or multiple according to actual needs. In this embodiment, the first monochromatic temperature-emitting light emitting element 410 is single, and the second monochromatic temperature-emitting light emitting element 420 is single, and the lamp module 400 is formed by connecting in series. Of course, in other embodiments, the first monochromatic temperature-emitting light emitting element 410 can be single, and the number of the second monochromatic temperature-emitting light emitting element can be multiple.

[0044] The present application also provides a dynamic lighting system in an exhibition hall, including the lighting device 10 with adjustable color temperature as described in any of the above embodiments.

[0045] In one embodiment, there are multiple lamp modules 400, and the multiple lamp modules 400 are electrically connected to the dynamic color temperature control unit 200 through the wires 300, and the multiple lamp modules 400 are used to be arranged in intervals in the display cabinet. It can be understood that the multiple lamp modules 400 are installed in the display cabinet at intervals to achieve a focused lighting effect on the exhibit 10a, and at the same time, the color temperature values ​​of the multiple lamp modules 400 can be adjusted to achieve a dynamic lighting effect on the exhibit 10a, thereby enhancing the visual perception and interest of the exhibit 10a.

[0046] Compared with the prior art, the present invention has at least the following advantages:

[0047] In the above-mentioned lighting device 10 with adjustable color temperature, the power supply module 100, the dynamic color temperature control component 200, the first monochromatic temperature light-emitting component 410 and the second monochromatic temperature light-emitting component 420 are electrically connected through the wire 300 respectively, the power supply module 100 outputs a voltage flowing through the dynamic color temperature control component 200, and the dynamic color temperature control component 200 outputs two groups of currents with different ratios to the first chip 411 and the second chip 421 respectively, so that the first monochromatic temperature light-emitting component 410 and the second monochromatic temperature light-emitting component 420 emit different brightnesses, and because the color temperature value of the first chip 411 and the color temperature value of the second chip 421 are set differently, that is, the color temperature of the light emitted by the first monochromatic temperature light-emitting component 410 and the second monochromatic temperature light-emitting component 420 is inconsistent, and the two groups of light with different color temperatures are mixed to emit the final required color temperature light, and the brightness ratio of the two groups of light affects the color temperature of the final light, and the color temperature of the mixed light can be adjusted according to the brightness ratio of the first monochromatic temperature light-emitting component 410 and the second monochromatic temperature light-emitting component 420. Furthermore, since the first monochromatic temperature-controlled light emitting component 410 and the second monochromatic temperature-controlled light emitting component 420 are each provided with only one chip, compared with the structure in which two or more groups of chips are provided inside the lamp of the traditional technology, the lamp body of the light emitting component of the present application is smaller in volume, and the light emitting surface diameter of the light source is smaller, thereby making the beam angle of the light emitting component smaller.

[0048] The above-mentioned embodiments only express several implementation methods of the present disclosure, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present disclosure, and these all belong to the protection scope of the present disclosure. Therefore, the protection scope of the patent of the present disclosure shall be based on the attached claims.
