[0039] Figure 1 is an exemplary schematic diagram of a light emitting method facing limited conditions according to some embodiments of the present specification.

[0040] Step 110, the limiting condition includes: the light emitted by the light source passes through the non-display surface of the light-transmitting plate that meets the light-transmitting condition, so that the display surface of the light-transmitting plate displays display light that meets the display condition.

[0041] A light source refers to a light emitting device that generates light. In some embodiments, the light emitting device of the light source may include one or more types. For example, the light emitting device may include one or more of a backlight module, a digital tube, and a light emitting diode. A light-transmitting plate refers to a medium for transmitting light. The light-transmitting plate includes a display surface and a non-display surface. The display surface refers to the surface of the light-transmitting plate used to display display light. The non-display surface refers to the surface of the light-transmitting plate used to receive light from the light source.

[0042] For more information about light sources and light-transmitting panels, see Figure 6 And related instructions.

[0043] Display light refers to the light presented on the display surface of the light-transmitting plate. Display light is also the light that the user ultimately hopes to obtain. In some embodiments, the display light can be different colors. For example, the display light can be white light, yellow light, blue light, cyan light, green light, orange light, purple light, red light, or any other color or a combination of multiple colors. For another example, when the display light is white light, the type of white light can also include multiple types. Exemplary, warm white light, cold white light, neutral white light, etc. The required display light is different, and the corresponding light source needs to emit different light. The light transmission conditions of the light-transmitting plate are also different. The user may refer to the operator of the light-emitting device. The operator may include the designer, user, etc. of the light-emitting device. For more information about the light-emitting device, please refer to Figure 6 Related description.

[0044] Limiting conditions refer to the restrictions on light sources, light-transmitting panels and display light.

[0045] In some embodiments, the limiting condition may also be other conditions, which may be set in advance manually or by a processor according to actual conditions.

[0046] Step 120: The light transmission condition includes a chromaticity coordinate range corresponding to the light transmission plate.

[0047] The light transmission condition refers to the transmission condition of the light from the light source through the light transmission plate. In some embodiments, the light transmission condition may include the transmission condition of light of different colors.

[0048] In some embodiments, the chromaticity coordinate range corresponding to the light-transmitting plate refers to the chromaticity coordinate region presented by the transmitted light of the CIE standard illuminant through the light-transmitting plate in the CIE standard colorimetry system. The CIE standard colorimetry system is a standard system for quantitatively describing colors. For example, the CIE standard colorimetry system may be the CIE1931 standard colorimetry system, etc.

[0049] In some embodiments, the light transmission condition may further include other conditions. The light transmission condition may be preset manually or by a processor according to requirements.

[0050] Step 130: the display condition includes a chromaticity coordinate range of the display light.

[0051] Display conditions refer to conditions related to display light. For example, the display conditions may include the chromaticity coordinate range and color temperature of the display light.

[0052] In some embodiments, the display conditions may also include other conditions, which may be set in advance by a human or a processor according to requirements.

[0053] Chromaticity coordinates are coordinates used to represent the color of light. Chromaticity coordinate range is the range of chromaticity coordinates corresponding to a certain color.

[0054] The chromaticity coordinate range of the display light refers to the chromaticity coordinate range corresponding to the light required to display the target color. The chromaticity coordinate corresponding to the display light refers to a certain chromaticity coordinate in the chromaticity coordinate range. Different colors of display light correspond to different chromaticity coordinate ranges.

[0055] In some embodiments, the chromaticity coordinates and the chromaticity coordinate range corresponding to the display light may be acquired in advance manually or by a processor.

[0056] Color temperature refers to the unit of measurement for the color of light. For example, color temperature can be expressed in K (kelvin). Different colors may have the same color temperature. It is understood that the chromaticity coordinates can fully reflect the color emitted by the light source, and the color temperature can roughly reflect the color emitted by the light source. The color temperature can be expressed as Tc.

[0057] Step 140, the light emitting method includes: the light source satisfies: the chromaticity coordinate range corresponding to the light source refers to the chromaticity coordinate range of the light source for displaying display light, and the light color adjustment range corresponding to the light source refers to the spectrum adjustment range of the light source for displaying display light.

[0058] In some embodiments, display lights of different colors have different chromaticity coordinate ranges of display lights and chromaticity coordinate ranges corresponding to the light sources. In some embodiments, display lights of different colors have different chromaticity coordinate ranges of display lights, chromaticity coordinate ranges corresponding to the light sources, and light color adjustment ranges corresponding to the light sources.

[0059] In some embodiments, the chromaticity coordinate area corresponding to the light-transmitting plate and the chromaticity coordinate area of ​​the display light can be acquired in advance manually or by a processor.

[0060] The luminescence parameters are parameters used to describe the luminescence characteristics of a light source. In some embodiments, the luminescence parameters may include intensity and a main wavelength spectrum half-width.

[0061] Intensity refers to the light intensity of the light emitted by a light source, which can be expressed as the luminous flux per unit solid angle in a given direction. Luminous flux refers to the light energy emitted by a light source per unit time.

[0062] The dominant wavelength spectrum half-width refers to the width corresponding to the half-height of the spectrum corresponding to the wavelength with the largest peak in the spectrum diagram of the light source. In some embodiments, the dominant wavelength spectrum half-width can be expressed in a variety of forms. For example, the dominant wavelength spectrum half-width can be expressed by the wavelength interval between two points of the spectrum line where the amplitude of the wavelength of the maximum peak drops by half. The narrower the dominant wavelength spectrum half-width, the better the monochromaticity of the light source, that is, the smaller the color error and the more uniform the color. In some embodiments, the dominant wavelength spectrum half-width can also be expressed in other forms, such as the root mean square spectrum width.

[0063] In some embodiments of the present specification, under the premise that the overall light intensity and the main wavelength remain basically unchanged, the half-width of the main wavelength is increased to achieve light source color enhancement, the transmitted light through the microcrystalline glass panel changes, and the color temperature also changes (usually the color temperature increases). In some embodiments of the present specification, under the premise that the overall light intensity and the main wavelength remain basically unchanged, the half-width of the main wavelength is reduced to achieve light source color reduction, the transmitted light through the microcrystalline glass panel changes, and the color temperature also changes (usually the color temperature decreases).

[0064] In some embodiments of the present specification, by using a light emitting method facing limited conditions, the light source and the light-transmitting plate can emit different lights under limited conditions to obtain different display lights to meet the display needs of users in different scenarios.

[0065] The following are some embodiments with specific limiting conditions, but they do not limit other embodiments in this specification.

[0140] Figure 6 is an exemplary schematic diagram of a light emitting device facing limited conditions according to some embodiments of this specification. Figure 6 As shown, the light emitting device 600 facing the defined condition may include a light source 610 and a light-transmitting plate 620 .

[0141] In some embodiments, the light emitting device of the light source may include one or more of an LED device, a fluorescent device, a quantum dot device, and the like.

[0142] In some embodiments, the light source 610 is configured to emit light to a non-display surface of the light-transmitting plate that meets the light-transmitting condition, so that the display surface of the light-transmitting plate displays display light that meets the display condition.

[0143] In some embodiments, the light transmission condition includes: a chromaticity coordinate range corresponding to the light transmission plate, and the chromaticity coordinate range corresponding to the light transmission plate refers to the chromaticity coordinate area presented by the transmitted light of the CIE standard illuminant through the light transmission plate in the CIE standard colorimetry system.

[0144] In some embodiments, the display condition includes a chromaticity coordinate range of the display light, where the chromaticity coordinate range of the display light refers to a chromaticity coordinate range of the transmitted light required for the display light to display a target color.

[0145] In some embodiments, the light source 610 satisfies: the chromaticity coordinate range corresponding to the light source refers to the chromaticity coordinate range that enables display light to be displayed, and the light color adjustment range corresponding to the light source refers to the light source spectrum adjustment range that enables display light to be displayed.

[0146] In some embodiments, the spectrum of the light source may include one or more intrinsic peaks. An intrinsic peak refers to an obvious peak appearing in the spectrum curve of the light source. It is understood that the luminous intensity of light with a wavelength corresponding to an intrinsic peak is higher.

[0147] In some embodiments, the spectrum of the light source may include 1 intrinsic peak. In some embodiments, the spectrum of the light source may include 2 intrinsic peaks. In some embodiments, the spectrum of the light source may include 3 intrinsic peaks. In some embodiments, the spectrum of the light source may include 4 intrinsic peaks. In some embodiments, the spectrum of the light source may include 1-4 intrinsic peaks. The number of intrinsic peaks included in the spectrum of the light source varies according to actual conditions. The number of intrinsic peaks can be designed and preset according to actual conditions.

[0148] In some embodiments of the present specification, the light source has multiple intrinsic peaks, so the spectrum of the light source can cover a wider wavelength range, thereby achieving richer color expression and meeting different requirements of users for display light.

[0149] In some embodiments, the light emitting device of the light source is a lighting element.

[0150] A lighting element refers to a light-emitting device that can only emit light of a specific wavelength. A lighting element may include one or more primary color lamps. A lighting element that includes only one primary color lamp is a monochromatic lighting element.

[0151] Primary color lamps refer to light-emitting devices used to display specific colors, such as red LED lamps, green LED lamps, blue LED lamps, etc.

[0152] In some embodiments, the monochromatic lighting element may include one primary color lamp, and the intrinsic peak range of the spectrum of the light source is between 440nm and 485nm. The lighting unit can stably provide the required lighting light, has stable performance, and is economical and durable.

[0153] In some embodiments, the monochromatic lighting element may include two primary color lamps, and the intrinsic peak ranges of the spectrum of the light source are between 440nm-495nm and between 520nm-570nm, respectively, and the primary color lamp with the intrinsic peak between 440nm-495nm is dominant. The lighting unit can provide more stable lighting light by complementary color in response to the wavelength shift caused by long-term use of the single primary color lamp LED.

[0154] In some embodiments, the light emitting device of the light source is a monochromatic lighting element, which includes three primary color lamps, and the intrinsic peak ranges of the spectrum of the light source are respectively between 440nm-495nm, between 495nm-520nm and between 520nm-570nm, and the primary color lamps with intrinsic peaks between 440nm-495nm are dominant. This lighting unit not only solves the problem of narrow light color adjustment range of a single primary color lamp and two primary color lamps, reduces the performance requirements for the blue light band primary color lamps, facilitates long-term use, but also can broaden the color gamut of the display, providing a new application direction for the next generation of aviation displays.

[0155] In some embodiments, the material of the light-transmitting plate may include multiple materials. For example, the light-transmitting plate may be a panel of microcrystalline glass, PMMA (acrylic), PC (polycarbonate) or other materials with light transmittance. Microcrystalline glass has excellent properties such as high hardness, corrosion resistance, pressure resistance, impact resistance, non-absorbent, less dust, and no radiation. Microcrystalline glass can be widely used in aerospace, architectural decoration, furniture life, consumer electronics and other fields. The light-emitting device of the microcrystalline glass panel used in architectural decoration and furniture life appliances is often composed of a dark or brown low-transparent colored microcrystalline glass panel sheet (substrate) and a signal light (light source). The microcrystalline glass panel with a signal light is often used as a display panel. The signal light informs the user about the working status of the device (on, standby, normal, abnormal, etc.), working time, and working mode through the display panel. In furniture life light-emitting devices (stove tops, freezers, etc.), small LED digital tubes are often used as lamps. In building curtain wall displays, LED panels, fluorescent lamps or quantum dot panels are often used as lamps.

[0156] The following Examples 11 to 13 are described using one intrinsic peak as an example.

[0157] Embodiment 11

[0158] Some embodiments of the present specification provide a white light emitting device based on a microcrystalline glass panel and a laser diode (LD) light source, and realizes the display of white light by transmitting the LD light source through the microcrystalline glass panel, including a microcrystalline glass panel and a light source composed of LD lamp beads. The microcrystalline glass panel used has a display surface, and the light source is located on the non-display side of the microcrystalline glass panel. At this time, its chromaticity coordinates are (0.0735, 0.3034), and the display is white.

[0159] In some embodiments, the spectrum of the light source used has one intrinsic peak, corresponding to a light-emitting lamp bead, wherein the characteristic peak (main wavelength) of the light-emitting lamp bead is 490nm, and the half-width is 485nm-495nm, a total of 10nm.

[0160] In some embodiments, due to the difference between the microcrystalline glass panel and the LD light source, the characteristic peak (main wavelength) and half-width of the light-emitting lamp bead vary according to the actual situation. This lighting method makes full use of the monochromaticity of LD, and the color gamut of the screen display is wider.

The microcrystalline glass panel used has a display surface, and the light source is located on the non-display side of the microcrystalline glass panel. At this time, its chromaticity coordinates are (0.0969, 0.2928), and the display is white.

[0163] In some embodiments, the spectrum of the light source used has one intrinsic peak, corresponding to a light-emitting lamp bead, wherein the characteristic peak (main wavelength) of the light-emitting lamp bead is 485nm, and the half-width is 475nm-495nm, a total of 20nm.

[0164] In some embodiments, due to the differences between the microcrystalline glass panel and the LED light source, the characteristic peak (main wavelength) and half-width of the light-emitting lamp bead vary according to the actual situation.

[0167] Some embodiments of the present specification provide a white light emitting device based on a microcrystalline glass panel and a blue light source, and a device that can display white light by transmitting a blue light source through a microcrystalline glass panel, including a microcrystalline glass panel and a light source composed of blue LED lamp beads, wherein the microcrystalline glass panel used has a display surface, and the light source is located on the non-display side of the microcrystalline glass panel, and the spectrum of the light source is as follows Figure 7 As shown, its chromaticity coordinates are (0.2837, 0.2905) at this time, appearing white.

[0168] In some embodiments, the spectrum of the light source used has one intrinsic peak, corresponding to a light-emitting lamp bead, wherein the characteristic peak (main wavelength) of the light-emitting lamp bead is 485 nm and the half-width is 30 nm.

[0169] The thickness of the microcrystalline glass panel used is 2.5mm, in a thin layer; within the visible light spectrum range of 380nm-780nm, the average transmittance is 5%, and the spectrum is as follows Figure 8 As shown, its chromaticity coordinates are (0.5791, 0.3383), which is within the color region of the microcrystalline glass panel.

[0170] After the light source is transmitted through the display surface of the micro-ceramic glass panel, its chromaticity coordinates are (0.2837, 0.2905), showing a cold white color. At this time, the spectrum of the light source is as follows: Fig. 9 shown.

[0171] Compared with the previous embodiment, this solution takes into account the problem of light source color enhancement caused by the increase in the half-width of the light source. The final display effect shows that the color difference provided by this solution is within an acceptable range, which provides a reference for the color tolerance of white light caused by the light color difference caused by the aging of the light source. The results show that the influence of light source color difference caused by long-term use or inconsistent production on the white light is acceptable, which also shows that this solution does not have high requirements on lighting components and is more suitable for promotion.
