Detailed ways

In order to improve or maintain people's concentration, alertness, and work efficiency during daytime work, lighting conditions with higher CS values (higher illumination, high color temperature, and high blue-green spectral intensity) are generally used to inhibit melatonin. secretion; when resting and relaxing at night, use lower CS value lighting conditions (lower illuminance, lower color temperature, lower intensity of blue-green light spectrum) to promote melatonin secretion. Such lighting conditions are more in line with the rhythmic needs of the human body. In real life, many people still work at night (such as overtime workers or shift workers). The original high illumination and high color temperature light used at night will affect people's rhythm, sleep quality and health; Light with low illuminance and low color temperature is used for work at night, which will affect work efficiency. The American Lighting Research Center LRC human experiment found that red light does not inhibit melatonin secretion, but can improve nighttime alertness and performance like white light (high blue light component).

In combination with the above research results, the present application provides a light source module and a luminaire that enables the emitted light to have a specific energy distribution in the red light region. The following describes a light source module proposed in the present application with reference to the accompanying drawings and some preferred embodiments that conform to the present application. and lamps for further details.

The light source module of the preferred embodiment provided by the present invention is a mixed light white LED package chip, which can be an LED chip with a general SMD package structure or a COB package structure. As shown in FIG. 1 , the light source module includes a base portion 9 , a red light generating portion 1 and a white light generating portion 2 disposed on the base portion 9 , and an encapsulating adhesive layer 8 covers the red light generating portion 1 and the white light generating portion 2 . The light emitted by the red light generating unit 1 is red light with a peak wavelength in the range of 600 nm or more to 780 nm or less, and preferably, the peak wavelength is in the range of 630 nm or more and 690 nm or less. The maximum spectral intensity of the light emitted by the red light generating part 1 is greater than the maximum spectral intensity of the light emitted by the white light generating part 2 . The LED chip (LED Chip) described in this application includes a front-mounted or a flip-chip, and a single LED Chip or a plurality of LED Chips are connected together in series, parallel or series-parallel. The white light generating unit 2 emits white light having a first color, hereinafter referred to as first white light. The red light emitted by the red light generating portion 1 and the first white light emitted by the white light generating portion 2 are mixed to form second white light having a second color. The addition of red light itself enhances the influence on people's concentration, so the maximum spectral intensity of the red light generating part 1 should be greater than the maximum spectral intensity of the white light generating part 2, that is, in the spectrum of the second white light after synthesis , the maximum spectral intensity is located in the range of 600nm to 780nm. Although the first white light and the second white light are both white light, due to the addition of red light, there is a slight deviation in color between the two, and they are located under the black body locus BBL on the CIE1931 chromaticity diagram, but both belong to the category of white light.

The red light emitted by the red light generating unit 1 is mainly concentrated in the wavelength band from 600 nm to 780 nm or less. We already know that red light has a certain effect on improving nighttime alertness, but in order to take into account the needs of lighting, we cannot blindly enhance this wavelength band. It has been verified through repeated tests that the spectral radiant energy of the red light emitted by the red light generating part 1 in the present embodiment in the range from 600 nm to 780 nm or more accounts for the second white light formed after mixing, that is, 380 nm or more in the visible light region. 30.0-50.0%, preferably 36.0-48.0%, of the total radiant energy within the range of 780 nm or less. Although the red light in the entire red light band between 600nm and 780nm can improve the alertness, the combination of experiments found that the proportion of red light in the 630nm to 690nm band is more important. Therefore, the ratio of the spectral radiant energy of the red light emitted by the red light generating part 1 in the range from 630 nm to 690 nm or more in the total radiant energy of the second white light in the visible light region is preferably 15.0-40.0%, It is preferably 18.0 to 35.0%. In this case, a red light source having a peak wavelength of emitted light in the range of 630 nm or more and 690 nm or less can be selected as the red light generating unit 1 . Of course, the light emitted by the red light generating part 1 will also exceed the range of 600nm to 780nm, but since its main energy is concentrated in this band, the excess part has little effect on the entire spectrum. We will not make specific restrictions here, as long as it can It can be ensured that the energy in the range of 600nm-780nm or the range of 630nm-690nm can achieve the effect of improving the alertness required by the application, and at the same time, it can ensure that the light color of the second white light meets the white light standard, and will not be too much. Influence indicators such as light color and color rendering. The color temperature of the second white light in this embodiment is in the range of 2500K to 6500K. As mentioned above, the correlated color temperature is located below the blackbody locus BBL on the CIE1931 chromaticity diagram due to the addition of red light. The distance Duv(BBL) on the CIE1931 chromaticity diagram is between (0.000, -0.015], preferably between [-0.003, -0.012].

Two methods are usually used to generate white light in the existing technology. The first is to use "blue light technology" to cooperate with phosphors to form white light; the second is to mix a variety of monochromatic light. The above two methods will include light generating parts of different colors. Therefore, the white light generating part 2 in this embodiment also includes several light emitting parts that generate different light colors. The light emitted from each light emitting part is mixed to generate the first white light. As shown in FIG. 1 , the white light generating portion 2 includes a blue light generating portion 21 , a green light generating portion 22 , and a yellow-orange light generating portion 23 . The blue light generating portion 21 emits light with a peak wavelength in the range of 430 nm or more to 470 nm or less, the green light generating portion 22 emits light with a peak wavelength in the range of 470 nm or more and 570 nm or less, and the yellow-orange light generating portion 23 emits light. Light with a peak wavelength in the range of 550 nm or more to 600 nm or less. In this embodiment, the blue light generating portion 21 , the cyan light generating portion 22 , and the red light generating portion 23 are all LEDs that emit monochromatic light, including blue light LEDs, green light LEDs, yellow light LEDs or orange light LEDs. In other preferred embodiments, the green light generating portion 22 can also be a phosphor powder that is excited by other light-emitting elements, such as blue LEDs, to convert light into light with a peak wavelength in the range of 470 nm or more to 570 nm or less. The yellow-orange light generating portion 23 can also be a phosphor powder that is excited by other light-emitting elements, such as blue LEDs, to convert light into light with a peak wavelength in the range of 550 nm or more to 600 nm or less. Of course, when the green light generating portion 22 and the yellow-orange light generating portion 23 are phosphor powders, they may be one type of phosphor powder, or may be a mixture of multiple phosphor powders with different components. When the green light generating portion 22 and the yellow-orange light generating portion 23 are phosphor powders, the phosphor powders are evenly distributed in the encapsulation adhesive layer 3 , and the light generated after being excited by the blue light generating portion 21 is mixed with the light emitted by the blue light generating portion 21 . form white light.

White light can also be generated by mixing blue light and yellow light alone. Therefore, in other preferred embodiments, the white light generating portion 2 may only include a blue LED, one of the green light generating portion 22, and the yellow-orange light generating portion 23. The present application This is not limited. Of course, the solution including the green light generating portion 22 and the yellow-orange light generating portion 23 at the same time has better color rendering. However, these embodiments all include blue light LEDs, and the lighting module provided by the present application is mainly used for night work, so as mentioned above, the blue light energy should not be too high, so as not to affect the secretion of melatonin. In this embodiment, the peak intensity of the light emitted by the blue light generating portion 21 is 20.0 to 98.0%, preferably 30.0 to 90.0%, of the peak intensity of the light emitted by the red light generating portion 1 . And the spectral radiant energy of the light emitted by the blue light generating part 21 in the range from 430 nm to 470 nm or less in the total radiant energy of the second white light in the visible light region is 4.0-30.0%, preferably 8.0- 20.0%.

The red light generating part 1 can be a red light LED or a phosphor that emits red light after excitation by a blue LED. When the red light generating part 1 is a phosphor, it can be used as the green light generating part 22 and the yellow-orange when the light source module is fabricated. The phosphor powder of the light generating portion 23 is mixed and mixed into the encapsulation adhesive layer 3 together. In this embodiment, the light source module is a packaged chip, but the light source module proposed in this application is not limited to this form. In other preferred embodiments, the light source module can also be an integrated type with circuits The light source module of the board, optical element and driving element, wherein the red light generating part 1 is a red light LED, the white light generating part 2 is a packaged white light LED chip, and the white light generating part 2 and the red light generating part 1 can respectively control the output separately . In some other preferred embodiments, the white light generating part 2 and the red light generating part 1 can be separate devices, such as LED light sources that can be used alone, but the above-mentioned spectral energy distribution ratios must be met to achieve the purpose of the invention proposed in this application. Therefore, we still believe that the LED light source combination form used in groups that conform to the above-mentioned spectral energy distribution is a kind of our light source module.

Since both the white light generating part 2 and the red light generating part 1 can have a variety of choices, in the following two tables, Table 1 gives some optional specific selections of the red light emitting part 1, where x and y represent the red light LEDs.
