The invention relates to the technical field of lamps, in particular to a packaged bowl-cup lamp with an adjustable light source.
Background
With the rapid development of lighting technology, intelligent lighting becomes hot to the hands. The development direction of intelligent illumination is sunlight. For general lighting, the color, brightness and color temperature of the lighting source can be changed along with the change of time, season, weather and the like, and meanwhile, the ultrahigh-quality sunlight-like lighting and the natural feeling and comfortable feeling of human eyes to the color can be ensured, in short, the technical index requirements for the lighting source are that the color temperature: realizing the arbitrary adjustment of the color temperature of 2000K-7000K; color rendering index: the color temperature is more than 95, the color temperature can be high, the color rendering index can be about 98, and in the process of adjusting the color temperature, the coordinate points are along the radiation line of the CIE black body.
And for plant illumination, as the name implies, is the light source used by the plant. The plant illumination simulation plant needs sunlight to carry out photosynthesis principle, and light is supplemented to the plant or the sunlight is completely replaced. The plant needs light of different wave bands in different growth periods such as seedling raising, growth, flowering and fruit bearing, the growth of the plant can be promoted by using LED plant lamp irradiation of a spectrum (light and quality combination) required by the plant, the flowering period can be prolonged, the flower quality is improved, as shown in figure 1, the spectrum required in the plant growth process is shown, plant photosynthesis needs to be carried out through chlorophyll, chlorophyll a and chlorophyll b are concentrated in blue-violet light at a left peak and red light at a right peak, and the 2 wave peaks can be absorbed by the plant. Lack of blue light can cause dwarfing or yellowing of the leaves. Lack of red light, low chlorophyll absorption rate, obvious influence on photosynthesis and photoperiod effect, and slow plant growth. Furthermore, the plants need to consume energy for "eating" and respiration as well as human beings, and the intensity of light when organic substances produced by the plants through photosynthesis are in equilibrium with substances consumed by respiration is called an optical compensation point, and the plants need to exceed the optical compensation point for normal growth, as shown in fig. 2. In order to meet the requirements of plants on light in different periods, the current plant lamps centralize light sources emitting different colors, and in order to control the light sources emitting different colors in the same device, different driving matching light sources are needed, so that the light sources emitting different colors can be simultaneously controlled in one device. The existing plant lamp control circuits are more, the production cost is higher, more circuits are provided, more heating devices are provided, more heat is generated, the light source is provided with heat generated by the light source, the heat generated by other devices is also born, and the lighting effect and the service life of the light source are greatly reduced.

an encapsulated bowl-cup lamp with an adjustable light source comprises four bowl cups which are separated from each other, as shown in fig. 3, 4 and 5, a light source 2 is arranged in a bowl cup 1 and is encapsulated by glue, the bowl cups are arranged on a chassis 3, and fluorescent powder is mixed in the glue of the two bowl cups.
In the bowl, the light sources of the first bowl and the second bowl are the blue LED chips with the wave band of 440-. The difference of the wave bands of the chips in each bowl cup is not more than 20nm, so that the accuracy of light emission is guaranteed, and subsequent adjustment is facilitated.
The first bowl is filled and sealed with glue mixed with red fluorescent powder, the red fluorescent powder comprises two types with wave bands of 620nm and 655nm, and the mass ratio range of the two types of red fluorescent powder is (2.2-2.4): (4.8-5.0). Wherein the relative spectral intensity of the blue light of the first bowl: relative spectral intensity of red light (0.15-0.25): 1.
the second bowl is filled and sealed with glue mixed with green fluorescent powder, the green fluorescent powder comprises three types with wave bands of 490-500nm, 535-537nm and 545-548nm, and the mass ratio range of the three types of green fluorescent powder is (3.4-3.6): (8.0-8.2): 4.8-5.0). Wherein the relative spectral intensity of blue light: relative spectral intensity of green light is (0.1-0.2): 1.
the following are some specific values of example 1, and as shown in fig. 6, in the CIE coordinates, the straight line connecting the coordinate point of the red light of the first bowl with the coordinate point of the green light of the second bowl, and the intersection point with the black body radiation line are located on the right of the coordinate point of the color temperature of 2500K. This ensures that the coordinate point varies along the black body radiation line when the light source is adjusted within the range of 2500K-8000K.
As shown in FIG. 7, the color rendering index can reach 98.9 at a color temperature of 4000K, with R1-R15 being greater than 95 except that R9 is 94.
Fig. 8 shows graphs of the color temperatures of 2700K and 4000K, which are close to the spectrum of a standard light source, so that the white light emitted from the light source is closer to the sunlight, and human eyes look comfortable and healthy. This light source may also be used as ambient light.
Fig. 9 shows the positions of the 4 bowls in the CIE diagram when lit individually. Although the color gamut of 4 bowls is not as large as that of full-color RGB lamps, the demand for atmosphere lamps by people has been met far more for lighting.
This embodiment no longer relies on different drives and light source to carry out the light and mixes, but through the difference of phosphor powder, can be so that corresponding bowl cup presents different colours, consequently can reduce drive module's quantity, guarantees simultaneously that the whole illumination effect after mixing accords with the task demand.

This allows to meet the specific requirements of the plants for light at different growth stages and for different plants.
The alternative scheme is mainly used for plant lamps, and the proportion of all the fluorescent powder is in order to meet the illumination requirement in the plant growth process. 400-500nm blue light is important for the differentiation and stomata regulation of plants. If the blue light is insufficient, the proportion of far-red light is too much, and the stem part grows excessively, so that the yellowing of the leaf is easily caused. The wavelength of 550nm promotes the growth of oxygen and helps tissues to better accumulate nutrients. When 655-. Therefore, along with the growth period of plants and the requirements of different plants, the light spectrum of the light source can be set by adjusting the current, so that the method is suitable for the growth of the plants. Therefore, the plant lamp can be fully utilized, the emitted light is fully absorbed by the plants, and unnecessary waste is avoided. As shown in fig. 10, are several spectra that were adjusted.
