Moreover, the relative optical power (i.e. relative light intensity) of the red band peaks of the two normalized spectrograms is lower than 0.75, and the bright red color is poor in display effect. Moreover, the red light wave band is connected with the green light wave band, yellow light is easily generated, the yellow light can influence the requirement of the fresh meat on the red saturation, and the brown color of consumers is easily misled, so that the problem that the existing fresh illuminating lamp generally exists is solved.
Referring to fig. 3 and 4, an embodiment of the invention provides a fresh lighting device 100, the fresh lighting device 100 is preferably applied to lighting fresh meat such as fresh pork and fresh beef, and the fresh lighting device 100 can greatly reduce the color of the fresh meat to promote the purchase of consumers. The fresh lighting device 100 can be selected from a fresh lighting lamp, or an electronic device such as a refrigerator and a freezer with a fresh lighting function. The invention provides a fresh lighting device 100, and the fresh lighting device 100 comprises a shell 10, a blue light chip 20, a red medium 30 and a green medium 40. The housing 10 has a cavity 101, the blue chip 20 is disposed in the cavity 101, and the red medium 30 and the green medium 40 are mixed and filled in the cavity 101 and cover the blue chip 20. The blue chip 20 excites the red medium 30 and the green medium 40 to emit white light.
Specifically, the blue chip 20 may be in a flip-chip or a flip-chip configuration. If the structure is a normal installation structure, the blue light chip 20 can be fixed on the shell 10 through the die bond adhesive, and is baked for 1-2H at 150 ℃ to completely cure the die bond adhesive. If the blue light chip is in the flip-chip structure, the blue light chip 20 can be fixed on the housing 10 by high-temperature solder paste, and reflow soldering is performed, wherein the reflow soldering maximum furnace temperature is 290 ℃, the time is about 30s, and the reflow soldering needs to be performed in a nitrogen environment, so that the solder is completely melted and completely attached to the blue light chip 20 and the housing 10. In addition, if the blue light chip 20 is in a forward-mounted structure, a wire bonding process is required, and the bonding wire is usually 0.9mil 80% Au, and an S or M wire loop process is adopted. The arrangement and connection mode of the bonding wires depend on the structure of the housing 10 and the structural matching of the blue light chip 20, and the circuit is conducted. The fresh lighting device 100 uses the chip LED lamp beads or the COB as the light source, and when using the chip LED lamp beads as the light source, the casing 10 is preferably an LED support, and when using the COB as the light source, the casing 10 is preferably an COB substrate.
Referring to fig. 5, the normalized spectrum of white light satisfies the condition:
the spectrogram comprises a red light wave band and a green light wave band, wherein the half-wave width of the red light wave band is 80-100 nm, the wave peak of the red light wave band is a first wave peak, the relative optical power corresponding to the first wave peak is 0.75-0.95, the wavelength corresponding to the first wave peak is 645-665 nm, the half-wave width of the green light wave band is 45-70 nm, the wave peak of the green light wave band is a second wave peak, and the wavelength corresponding to the second wave peak is 500-520 nm. Specifically, the half-wave width of the red light band may be selected from 80nm, 84nm, 86nm, 89nm, 94nm, 96nm, 100nm, etc., preferably 100nm, and the half-wave range is 610nm to 710 nm. The relative optical power corresponding to the first peak may be selected to be 0.75, 0.79, 0.84, 0.89, 0.93, 0.95, etc. The wavelength corresponding to the first peak can be 645nm, 646nm, 649nm, 653nm, 659nm, 663nm, 665nm, etc., preferably 660 nm. The half-wave width of the green light wave band can be selected from 45nm, 46nm, 49nm, 53nm, 55nm, 61nm, 67nm, 69nm, 70nm and the like, preferably 70nm, and the half-wave range is 480 nm-550 nm. The wavelength corresponding to the second peak can be selected from 500nm, 503nm, 509nm, 511nm, 516nm, 519nm, 520nm, etc.
It can be understood that if the half-wave width of the green light wave band is below 45nm, the process cost is high, the color is easy to be out of order, the white color is easy to be distorted, and the color reduction of the white part of the fresh meat is not facilitated; if the half-wave width of the green light wave band is more than 70nm, the proportion of white light occupied by the green light wave band is too large, interference with red light is generated, red color is easy to distort, and the color development of the red part of the fresh meat is not facilitated. Through the scheme that the blue light chip 20 is arranged to excite the red medium 30 and the green medium 40, the wavelength corresponding to the first peak of the excited red light wave band is between 645nm and 665nm, the penetrating power of red light is strong, the color and luster of fresh food are well restored, the relative optical power corresponding to the first peak is between 0.75 and 0.95, and the red display effect is good. Simultaneously, the wavelength that the second crest of green glow wave band corresponds is between 500nm and 520nm, and the half-wave width of green glow wave band is between 45nm and 70nm, and the red glow wave band is difficult to disturb and is difficult to produce the yellow light to the green glow wave band, avoids the yellow light to influence the demand of fresh meat to red saturation to further improve fresh lighting color reduction degree, avoid appearing the brown that influences the purchase desire, can demonstrate the red that comparatively matches with fresh meat.
In one embodiment, referring to fig. 5, the relative optical power corresponding to the second peak is 0.4 to 0.7. Specifically, the relative optical power corresponding to the second peak may be selected from 0.4, 0.5, 0.6, 0.7, and the like. By setting the relative optical power of the second peak between 0.4 and 0.7, it is avoided that the green light is saturated too much, resulting in red distortion, and that the saturation is too low, resulting in white distortion.
In one embodiment, referring to fig. 5, the normalized spectrogram further includes a yellow light band, the yellow light band corresponds to a wavelength range of 560nm to 590nm, and the relative optical power of the yellow light trough is 0.05 to 0.25. Specifically, the left side of the yellow light band is connected with the green light band, and the right side is connected with the red light band. The yellow light band is concave, i.e. the relative optical power of the left and right sides of the yellow light band is higher than that of the middle part. The relative light power of the yellow light trough is set between 0.05 and 0.25, so that the generation of yellow light is further reduced, the condition that the yellow light influences the requirement of the fresh meat on the red saturation is avoided, the brown color is caused, and the red color which is matched with the fresh meat is presented.
In one embodiment, referring to fig. 5, the normalized spectrogram further includes a blue light band, and the half-wave width of the blue light band is 15nm to 30 nm. Specifically, the half-wave width of the blue light band can be selected from 15nm, 17nm, 19nm, 22nm, 26nm, 29nm, 30nm and the like, wherein 15nm is preferred, and the half-wave range is 435 nm-465 nm. By meeting the requirement that the half-wave width of the blue light wave band is between 15nm and 30nm, the blue light wave band can produce white which meets the requirements of fresh and fresh products, and can not influence the color development of the fresh and fresh red. It can be understood that when the half-wave width of the blue light band is below 15nm, the process is difficult and the requirement for the wafer substrate is high. When the half-wave width of the blue light wave band is more than 30nm, the overall brightness of the wafer is greatly reduced, white light is easily disordered to show a tragic white color, and the vivid effect of the white part is not facilitated.
The wave peak of the blue light wave band is a third wave peak, the relative optical power corresponding to the third wave peak is 0.9-1, and the wavelength corresponding to the third wave peak is 445 nm-455 nm. Specifically, the relative optical power of the third peak may be selected from 0.9, 0.91, 0.93, 0.96, 0.98, 1, and the like, and is preferably 1. The wavelength corresponding to the third peak can be selected from 445nm, 447nm, 449nm, 451nm, 452nm, 454nm, 455nm, etc., wherein 450nm is preferred. Relative luminous power through setting up the third crest is between 0.9 and 1, when not influencing white colour development, can also carry out better red colour development, is favorable to avoiding giving birth to bright illumination distortion. The wavelength corresponding to the third peak is between 445nm and 455nm, so that white meeting the fresh requirement of a white part can be well produced.
It will be appreciated that the first peak of the red wavelength band corresponds to a relative optical power between 0.75 and 0.95, the green wavelength band between 0.4 and 0.7 and the third peak of the blue wavelength band between 0.9 and 1 in order to define the spectral radiance distribution accurately.
In one embodiment, referring to fig. 5, the normalized spectrogram further includes a cyan light band, the wavelength range corresponding to the cyan light band is 460nm to 490nm, and the relative optical power of the cyan light trough is 0.15 to 0.35. Specifically, the left side of the blue light band is connected with the blue light band, and the right side of the blue light band is connected with the green light band. The cyan wavelength band is concave, i.e. the relative optical power corresponding to the left and right sides of the cyan wavelength band is higher than the relative optical power corresponding to the middle part. Relative optical power through setting up the blue or green light trough is between 0.15 and 0.35, has reduced the formation of blue or green light, avoids the blue or green light to influence the bright red presentation of giving birth to and avoid the blue or green light to influence the bright white presentation of giving birth to, be favorable to improving the bright effect that shows of giving birth to bright meat.
In one embodiment, referring to fig. 5, the normalized spectrogram further includes a violet band, the wavelength range corresponding to the violet band is 350nm to 420nm, and the relative optical power of the violet band is lower than 0.1. Specifically, the violet band is connected to the left side of the blue band. The violet band decreases (substantially does not change after decreasing to a certain degree) with a decrease in the corresponding wavelength. By satisfying that the relative optical power of the violet band is lower than 0.1, the method is beneficial to reducing the probability of appearing tragic white and further improving the fresh effect of white parts.
In one embodiment, referring to fig. 5, the normalized spectrogram further includes an infrared band adjacent to the red band, the infrared band corresponding to a wavelength greater than 780nm, and the relative optical power of the infrared band is less than 0.1. Specifically, the left side of the infrared band is connected to the red band. By meeting the requirement that the relative optical power of the infrared light wave band is lower than 0.1, the saturation of red light is favorably improved, and the fresh effect of a red part is improved.
In one embodiment, referring to FIG. 5, the red dielectric 30 comprises a nitride, the green dielectric 40 comprises beta-Sialon and/or a silicate, and the blue chip 20 comprises gallium nitride (GaN). Specifically, the green dielectric 40 may include only one of beta-Sialon and silicate, or both beta-Sialon and silicate. It can be understood that the above materials can determine the half wave widths and the wavelength positions corresponding to the wave crests of the red light wave band, the blue light wave band and the green light wave band, which is beneficial to obtaining the white light according with the normalized spectrogram provided by the embodiment of the invention.
In one embodiment, referring to fig. 5, the ratio of the red medium 30 to the green medium 40 ranges from 1:13 to 1:4. Specifically, the ratio of the red medium 30 to the green medium 40 may be selected from 1:13, 1:12, 1:9, 1:7, 1:6, 1:5, 1:4.5, 1:4, and the like. By adapting the mixing ratio of the red medium 30 and the green medium 40, it is advantageous to adjust the heights (relative optical powers) of the first peak, the second peak and the third peak in order to accurately define the radiation distribution of the spectrum.
In one embodiment, referring to fig. 5, the fresh lighting device 100 further includes an encapsulant 50 filled in the cavity 101. The mixing ratio of the mixture of the red medium 30 and the green medium 40 to the packaging colloid 50 is 1: 8-1: 1.8. Specifically, the ratio of the mixture of the red medium 30 and the green medium 40 to the encapsulant 50 may be selected from 1:8, 1:7, 1:6, 1:5.5, 1:5, 1:4.5, 1:3, 1:2, 1:1.8, and the like. The mixture of the red medium 30 and the green medium 40 and the packaging colloid 50 are oscillated by a stirrer to be uniformly mixed, wherein the stirring condition can be 200-400 s, and the speed is 1000-2000 n/min, so that the packaging colloid 50 and the green medium 40 are uniformly mixed. In addition, after the mixture of the encapsulation colloid 50 and the green medium 40 is encapsulated in the cavity 101 of the shell 10, the mixture is cured by baking for 3-4H at 150 ℃, so that encapsulation is completed. It will be appreciated that a further accurate definition of the spectral radiation distribution is facilitated by the green medium 40 being mixed with the encapsulant 50 in a ratio between 1:12 and 1:2, so as to adjust the heights of the first, second and third peaks.
