[0002] Figure 1 The spectrum of a metal halide lamp used for attracting fish using light is shown in the prior art.

[0003] Currently, metal halide lamps are the main light source used for light-induced emission in the fishing industry. The working principle of metal halide lamps is to generate an electric arc discharge and emit light in a mixture of mercury and metal halide vapor. Depending on the metal halide filling, different metal halide lamps have different spectral characteristics.

[0004] Metal halide lamps have spectra composed of discontinuous peaks. Due to the discontinuity of the spectrum, metal halide lamps have low luminous efficiency and consume more energy than LED light sources under the same illuminance.

[0045] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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 are within the scope of protection of the present invention.

[0046] It should be noted that, Figure 1 The spectrum shown in the schematic diagram is the spectrum of the metal halide lamp that the light-emitting component of this embodiment of the invention needs to simulate. Therefore, some of the accompanying drawings are incorporated into the schematic diagram. Figure 1 The spectrum is used as a reference.

[0047] Figure 2 The spectral diagram of the light-emitting component according to an embodiment of the present invention is shown. Specifically, since this group contains light source spectra with many variable characteristics, Figure 2 The spectrum of only one embodiment of the light-emitting component is shown.

[0048] Specifically, this embodiment of the invention provides a light-emitting component, including a plurality of purple LED beads and a plurality of white LED beads; specifically, purple LED beads refer to LED beads that emit purple light, and white LED beads refer to LED beads that emit white light.

[0049] The light emission of the LED bead is determined by the LED chip inside the bead and the color conversion materials such as phosphor that may be used. In this embodiment of the invention, the purple LED bead includes a purple LED chip, and the purple LED bead emits light based on the purple LED chip; the white LED bead includes a blue LED chip and phosphor, and the white LED bead emits light based on the blue LED chip exciting the phosphor.

[0050] In actual implementation, depending on the limited conditions, other structures of LED beads can be used in combination with actual needs. This embodiment of the invention is only described by taking one implementation method as an example.

[0051] The light-emitting component emits light based on a combination of the purple LED beads and the white LED beads, and the spectral characteristics of the light-emitting component include:

[0052] There is a first peak in the wavelength range of [400nm, 410nm], and the relative luminous intensity of the first peak ranges from [20%, 40%].

[0053] There is at least a second peak in the wavelength range of [445nm, 470nm], and the relative luminescence intensity of the second peak ranges from [35%, 55%].

[0054] There is a third peak in the wavelength range of [580nm, 600nm], and the relative luminescence intensity of the third peak ranges from [90%, 100%].

[0055] The relative luminous intensity within the wavelength range of [510nm, 520nm] ranges from [45%, 60%];

[0056] The relative luminous intensity within the wavelength range of [530nm, 550nm] ranges from [45%, 60%];

[0057] The relative luminous intensity ranges from 20% to 40% within the wavelength range of [660nm, 670nm].

[0058] Specifically, the light-emitting component in this embodiment of the invention is mainly used to replace metal halide lamps used for attracting fish with light. Metal halide lamps primarily target chuatsiidae and scombridae fish. Chuatsiidae and scombridae are two important economic fish species worldwide. Under dark adaptation conditions (illuminance ≤ 0.5 lx), chuatsiidae fish exhibit the highest phototaxis to blue and green light. After transitioning from dark adaptation to light adaptation (illuminance between 0.5 and 100 lx), the colors with the highest phototaxis shift towards green and yellow light. Chuatsiidae fish, under both dark adaptation (illuminance ≤ 0.5 lx) and light adaptation (≥ 100 lx) conditions, show the greatest phototaxis to violet and red light.

[0059] Correspondingly, the luminescence characteristics of metal halide lamps can well meet the attraction needs of trevally and mackerel. According to the luminescence characteristics of metal halide lamps, this invention uses a combination of LEDs to achieve a similar function, thereby overcoming the disadvantages of metal halide lamps such as high energy consumption and serious pollution.

[0060] Specifically, the violet LED lamp bead includes a violet LED chip, and the violet LED lamp bead emits light based on the violet LED chip; the peak wavelength of the violet LED chip ranges from [400nm, 410nm]. The violet LED lamp bead is mainly used to provide light with a wavelength peak around 405nm to simulate the relevant wavelength peaks of metal halide lamps. Since the violet LED lamp bead provides light with a wavelength peak around 405nm, the white LED lamp bead only needs to simulate the light from the remaining wavelength peaks of the metal halide lamp to meet the specific requirements.

[0061] Specifically, refer to the attached diagram. Figure 1 Referring to the spectrum of metal halide lamps, metal halide lamps have certain peak characteristics in the wavelength range of [445nm, 470nm]. Correspondingly, since the wavelength range of [445nm, 470nm] corresponds to blue light, in order to simulate the relevant peak characteristics, it is necessary to select a suitable blue light chip in white LED lamp beads.

[0062] In this embodiment of the invention, the implementation of white LED chips includes two methods: using a single-band (one type) blue light chip and using a dual-band (two types) blue light chip. Specifically, Figure 3 The diagram shows the spectrum of a single-band blue light chip used in a white LED lamp bead according to an embodiment of the present invention. Figure 4 The spectrum of the white LED lamp bead using a dual-band blue light chip according to an embodiment of the present invention is shown.

[0063] Specifically, when white LED chips use single-band blue light chips, a second peak will exist in the wavelength range of [445nm, 470nm]. Depending on the type of blue light chip used, only one second peak will occur within the corresponding wavelength range. In this embodiment of the invention, the single-band blue light chip used in the white LED chips is a first-type blue light chip with an emission peak wavelength located in the range of [440nm, 470nm]. In specific implementation, the single-band chip is a first-type blue light chip with a peak wavelength near 450nm. Combined with... Figure 3 As shown, the spectrum of the light-emitting component has only a second peak with high light intensity near the wavelength of 450 nm.

[0064] Specifically, when white LED chips use dual-band blue light chips, due to the presence of two blue light chips in two bands, two peaks will be generated within the wavelength range of [445nm, 470nm]. One of these peaks is considered the second peak, and the other is a fourth peak distinct from the second. Specifically, the dual-band blue light chips used in white LED chips are a combination of a second-type blue light chip with an emission peak wavelength range of [445nm, 455nm] and a third-type blue light chip with an emission peak wavelength range of [460nm, 470nm]. Combined with... Figure 4 As shown, the spectrum of the light-emitting component produces a second peak at a wavelength of 450 nm, and a fourth peak at a wavelength of 465 nm.

[0065] For the simulation of metal halide lamps, simulating the spectral peaks of a metal halide lamp essentially involves analyzing the spectral characteristics of the lamp and identifying its peaks. During the simulation, the light intensity at the wavelength corresponding to the peak is made to be as high as possible, either greater than a preset value or within a preset range. The implementation of the blue light chip in white LED chips primarily affects the spectral characteristics within the [445nm, 470nm] wavelength range. This is achieved through analysis... Figure 1 , Figure 3 and Figure 4The spectral characteristics of metal halide lamps in the [445nm, 470nm] wavelength range mainly have two peaks (corresponding to two wavelengths). If the white LED lamp beads adopt a single-band blue light chip implementation, the power of the blue light chip needs to be significantly increased so that the light intensity at the two wavelengths corresponding to the two peaks can meet the simulation requirements. The adverse effect is that while meeting the simulation requirements, it will destroy the overall spectral characteristics of the light-emitting component in the [445nm, 470nm] wavelength range. If the white LED lamp beads adopt a dual-band blue light chip, the two peaks of the metal halide lamp in this range can be simulated well by using two types of blue light chips respectively, without affecting the light intensity characteristics at other wavelengths, thus achieving a better simulation effect and attracting fish more effectively.

[0066] Furthermore, regarding the specific implementation of white LED chips, in addition to the selection of blue light chips, to simulate the peak characteristics at other wavelength positions, it is also necessary to change the composition of different wavelengths of the emitted light using materials such as phosphors. Specifically, in this embodiment of the invention, based on the simulation effect of a metal halide lamp, the phosphor includes:

[0067] Green phosphor, wherein the peak emission wavelength of the green phosphor is in the range of [490nm, 510nm];

[0068] Yellow phosphor, wherein the emission peak wavelength of the yellow phosphor is in the range of [510nm, 550nm];

[0069] The red phosphor has an emission peak wavelength range of [590nm, 610nm].

[0070] Correspondingly, the light emitted by the blue light chip excites the green, yellow, and red phosphors, primarily to provide light near 510nm, 540nm, 570nm, 600nm, and 670nm to simulate the relevant wavelength peaks of a metal halide lamp. In practical implementation, compared to directly using RGB chips to mix and generate white light, using phosphors can achieve a wider half-wavelength, resulting in a more uniform white light spectrum and a better simulation of a metal halide lamp.

[0071] In an optional embodiment, the green phosphor is any one or more of oxynitride green phosphor, aluminate green phosphor, silicate green phosphor, and halophosphate green phosphor. Specifically, the material used for the green phosphor can be any one or more of BaSi₂O₂N₂:Eu, Ba₂SiO₄:Eu, and (BaSr)₂SiO₄:Eu.

[0072] In an optional embodiment, the yellow phosphor is any one or more of GaAG yellow phosphor, LuAG yellow phosphor, YAG yellow phosphor, nitride yellow phosphor, aluminate yellow phosphor, silicate yellow phosphor, and halophosphate yellow phosphor. Specifically, the material used for the yellow phosphor can be La3Si6N. 11 Ce、Y3Al5O 12 Ce、Y3(Al,Ga)5O 12 Ce, Lu3Al5O 12 Ce, BaSi2O2N2:Eu and (Y 1-x / Ga x )3Al5O 12 :Ce any one or more of them, etc.

[0073] In an optional embodiment, the red phosphor is any one or more of nitride red phosphor, oxynitride red phosphor, sulfide red phosphor, fluoride red phosphor, and nitride red phosphor. Specifically, the material used for the red phosphor can be CaAlSiN3:Eu, SrAlSiN3:Eu, (Ca... 1-x Sr x AlSiN3:Eu, CaS:Eu and Ca(GeS):Eu, or any one or more of them.

[0074] Specifically, when the light-emitting component adopts a dual-band blue light chip implementation, since blue light chips of different bands have different excitation efficiencies for the same phosphor, and chips of the same band also have different excitation efficiencies for phosphors of different wavelengths, it is necessary to adjust the corresponding phosphor ratio to obtain the target spectrum required for simulating metal halide lamps. Since the phosphors involve three colors, in order to make better comparisons, the influence of the corresponding phosphor on the spectrum of the light-emitting component is generally studied by adjusting the amount of a single phosphor.

[0075] Specifically, Figures 5 to 8 This diagram illustrates a comparison of the spectra of white LED chips with metal halide lamps under different phosphor combinations according to an embodiment of the present invention. The white LED chips are excited using a dual-band blue light chip, with the total mass of phosphor and the amount of red phosphor remaining constant. The corresponding spectral characteristic diagrams of the light-emitting components are generated by adjusting the ratio of green and yellow phosphors. Specifically, in... Figure 5 In the corresponding implementation, the mass ratio of green phosphor to yellow phosphor is 1:0.2. Figure 6 In the corresponding embodiment, the mass ratio of green phosphor to yellow phosphor is 1:0.4. Figure 7 In the corresponding embodiment, the mass ratio of green phosphor to yellow phosphor is 1:0.65. Figure 8 In the corresponding implementation, the mass ratio of green phosphor to yellow phosphor is 1:1.

[0076] In addition, Table 1 shows the light intensity data of the light-emitting component in the characteristic wavelength range under different amounts of yellow phosphor in the form of specific data.

[0077]

[0078] Table 1

[0079] Comparative analysis shows that the mass ratio of green phosphor to yellow phosphor mainly affects the light intensity of white LED chips in the 440nm, 470nm, 510nm, and 540nm wavelength range. This is because blue light near 440nm primarily excites green phosphor, while blue light near 470nm primarily excites yellow phosphor. When adjusting the ratio of green to yellow phosphor, increasing the ratio indicates a decrease in green phosphor and an increase in yellow phosphor. Therefore, as the amount of yellow phosphor increases, the light intensity of the 530nm-550nm wavelength range increases, while the blue light in the 460-470nm wavelength range weakens due to absorption by the yellow phosphor. Simultaneously, as the amount of yellow phosphor increases, the amount of green phosphor decreases accordingly. Therefore, as the amount of green phosphor decreases, the intensity of green light in the 510nm-520nm wavelength range weakens, while the intensity of blue light near 440nm increases.

[0080] Based on this, and considering the simulation of metal halide lamps, when the feasible range of the ratio of yellow phosphor to green phosphor is [0.4, 0.8], the light intensity of the light-emitting component at wavelengths of 450nm, 470nm, 510nm, and 570nm can maintain good consistency with that of the metal halide lamp.

[0081] Furthermore, when the ratio of yellow phosphor to green phosphor is between 0.6 and 0.7, the simulated spectral characteristics of the metal halide lamp are optimal, and the corresponding spectral characteristics of the light-emitting component are as follows:

[0082] There is a second peak in the wavelength range of [445nm, 455nm], and the relative luminescence intensity of the second peak ranges from [40%, 50%].

[0083] There is a fourth peak in the wavelength range of [460nm, 470nm], and the relative luminescence intensity of the fourth peak ranges from [40%, 50%].

[0084] The relative luminous intensity within the wavelength range of [510nm, 520nm] ranges from [50%, 60%];

[0085] The relative luminous intensity ranges from 50% to 60% within the wavelength range of [530nm, 550nm].

[0086] Based on a similar implementation principle, in order to control the relative luminous intensity near the 600nm wavelength and the relative luminous intensity near the 670nm wavelength in the spectrum of the white LED lamp beads, so that the spectrum of the light-emitting component is similar to that of the metal halide lamp, the mass percentage of the red phosphor in the phosphor is in the range of [4%, 7%].

[0087] Based on the above implementation, Figures 9 to 14 This diagram illustrates a comparison of the spectra of a light-emitting component according to an embodiment of the present invention with those of a metal halide lamp, achieved by combining different proportions of violet LEDs and white LEDs. The spectra were obtained by measuring light-emitting components with varying proportions of violet and white LEDs while maintaining the same current. Figure 9 In this implementation, the ratio of violet LED beads to white LED beads is 1:3. Figure 10 In this implementation, the ratio of violet LED beads to white LED beads is 1:4. Figure 11 In this implementation, the ratio of violet LED beads to white LED beads is 1:5. Figure 12 In this implementation, the ratio of violet LED beads to white LED beads is 1:6. Figure 13 In this implementation, the ratio of violet LED beads to white LED beads is 1:7. Figure 14 In this implementation, the ratio of violet LED beads to white LED beads is 1:8.

[0088] In addition, Table 2 shows the light intensity data of the light-emitting components in the characteristic wavelength range for different numbers of white LEDs in the form of specific data.

[0089]

[0090] Table 2

[0091] Specifically, the spectrum primarily represents the relative proportion of light intensity at a specific wavelength to the total light intensity, rather than the absolute value of light intensity at that wavelength. Therefore, even if each LED chip can effectively simulate the spectral characteristics of a metal halide lamp within its corresponding wavelength range, the simulation effect will change when two different LED chips are combined into a light-emitting component due to variations in the total light intensity. In the spectrum of the light-emitting component, the spectral characteristics corresponding to the LED chips may be proportionally amplified or reduced (specifically, the spectrum in the corresponding wavelength range will shift upwards or downwards). Therefore, it is necessary to adjust the amount of different LED chips used in the light-emitting component so that the overall luminous characteristics of the combined component meet the requirements for simulating the spectral characteristics of a metal halide lamp.

[0092] Combination Figures 9 to 14 The illustration shows that by adjusting the ratio of violet LEDs to white LEDs, when the ratio is between 1:8 and 1:3, the spectral characteristics of the light-emitting component in the wavelength range corresponding to the white LEDs remain basically unchanged, while the spectral characteristics of the light-emitting component in the wavelength range (400nm to 410nm) corresponding to the violet LEDs change. As the ratio increases, the relative luminous intensity of the light-emitting component in the 400nm to 410nm wavelength range is significantly enhanced.

[0093] Specifically, based on the spectral simulation effect of metal halide lamps, when the ratio of the number of purple LED beads to the number of white LED beads is in the range of 1:8 to 1:4, the spectrum of the light-emitting component can simulate the spectrum of the metal halide lamp very well.

[0094] Furthermore, considering practical application factors, when the ratio of violet LEDs to white LEDs is greater than 1:5, the relative peak intensity of light near the 405nm wavelength is relatively high, and the strong ultraviolet light can harm the human body and the surrounding environment. Therefore, in practical use, the ratio of violet LEDs to white LEDs should not exceed 1:5. Conversely, when the ratio is less than 1:6, the relative intensity of light near the 405nm wavelength is relatively low, resulting in poor fish attraction. Therefore, in practical use, the ratio of violet LEDs to white LEDs should not be less than 1:6. Therefore, in specific implementations, the optimal ratio of violet LEDs to white LEDs in the light-emitting component should be 1:5 or 1:6. It should be noted that in other embodiments, the corresponding LED ratio can also be adjusted using the same voltage and power.

[0095] Furthermore, regarding the specific structure of the purple LED beads and the white LED beads, in specific implementations, both types of beads can adopt COB packaging structures or other structures; specifically, based on this, regarding the specific implementation structure of the light-emitting component, optionally, the light-emitting component can adopt a bulb, light strip, or other implementation structure.

[0096] This invention discloses a light-emitting component that uses a combination of violet LEDs and white LEDs to simulate the spectrum of a metal halide lamp, thereby replacing the metal halide lamp with LEDs. The LEDs are a combination of violet LEDs and white LEDs based on blue LED chips exciting phosphors, resulting in low implementation costs. By rationally configuring the number of violet and white LEDs, the spectrum of a metal halide lamp can be simulated relatively accurately, with good simulation results. In the white LEDs, two blue LED chips of different wavelengths are used to excite the same phosphor, overcoming the limitation of a single-wavelength blue LED chip in accurately simulating the metal halide lamp spectrum, thus improving the performance of the light-emitting component. The simulation effect of metal halide lamps is demonstrated. Furthermore, by using phosphors in appropriate proportions within white LED chips, the excitation requirements of two blue light chips in the white LED chip can be simultaneously met, achieving the multiple peak characteristics required by metal halide lamps within a single white LED chip, demonstrating good practicality. Due to the continuity of the LED chip spectrum, this light-emitting component has advantages such as high luminous efficiency, low energy consumption, and high color rendering index. Moreover, since the majority of the LED chip spectrum is concentrated in the visible light region, this light-emitting component can reduce the damage of invisible light to the ecological environment. In addition, since the production process of LED chips does not involve the use of heavy metal materials, this light-emitting component is more environmentally friendly than metal halide lamps.

Specific examples have been used to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of the present invention.

Therefore, the content of this specification should not be construed as a limitation of the present invention.
