Problems solved by technology

[0013] In view of the deficiencies in the prior art, the object of the present invention is to provide an indoor saffron planting rack lighting fixture and its application that are convenient for automatic observation. and filigree elongation, leading to the problem of depreciation and production reduction. At the same time, it improves the shortcomings of existing indoor plant lighting lamps such as poor heat dissipation, high cost, low radiation efficiency, and large light attenuation, so that the lamps have low power density, good heat dissipation performance, and radiation efficiency. High, low cost, adjustable spectrum, high color rendering index and many other advantages

Embodiment 1

[0053] Taking the indoor planting fully turned on red LED surface light source as an example, explain the specific lighting method and light intensity. Figure 5 It represents the simulation result of the equal PPFD curve irradiated by the all-red LED surface light source module of the present invention. The lighting design software was used to simulate and simulate, and the planting frame was set to be 0.95 m long, 0.6 m wide, and the layer spacing was 0.4 m. The reflectance of the top was set to 60%, the reflectance of the tray containing saffron bulbs was 10%, and the distance from the light-emitting surface of the transparent glass to the tray was 0.3 m. Set the average photon density PPFD required for saffron to be 100 μmolm −2 the s −1 , while the conversion factor of optical quantum system-radiometric system K PPF,e is 4.31 μmol s −1 W −1 , then, the calculated irradiance required for saffron is 23.2 W m -2 . Since the red light LED surface light source module ...

Embodiment 2

[0063] Figure 8 Indicates that the red, yellow and blue LED surface light source is turned on at the same time, and the indoor spectrum satisfies better color rendering index and color tolerance under different color temperatures. Therefore, the peak wavelength of the red LED surface light source is 650 nm, the peak wavelength of the yellow LED surface light source is 553 nm, and the peak wavelength of the blue LED surface light source is 455 nm. By writing a program, the ratio of red, yellow and blue three-color spectrum is preliminarily calculated, and 10 is obtained by fitting 3 spectrum. And optimize the parameter range, select the color rendering index R aAbove 85, the color tolerance Duv is within ±0.005, which is close to the spectrum of the representative color temperature of the black body radiation, and the color temperature traverses from 2700 K to 6000 K.

[0064] Table 4 shows the color rendering index of different ratios of red, yellow and blue LED surface l...

Abstract

The invention discloses an indoor stigma croci planting frame lighting lamp convenient for automatic observation and application. The lamp comprises a red, yellow and blue LED area light source module, a heat conduction aluminum plate, a driving power source, a controller, a sensor, a feedback device, a camera and a remote control system; the lamp can emit red light and blue light with different intensity ratios to provide illumination for indoor stigma croci flower bud differentiation and filament extension, and can also emit yellow light with different intensities, so that the LED lamp can emit white light with the color rendering index Ra being more than 85, the color tolerance Duv being close to black-body radiation rays in the range of + / -0.005 and the color temperature being adjustable in a large range; and the growth condition of the stigma croci on the planting frame can be conveniently and manually observed or automatically detected. The problem that existing indoor stigma croci planting excessively depends on natural illumination is solved, the lamp has the advantages of being low in power density, good in heat dissipation performance, high in radiation efficiency, low in cost, adjustable in spectrum and the like, and indoor planting of stigma croci and manual or automatic observation are facilitated.

Description

technical field [0001] The invention belongs to the technical field of plant lighting, and in particular relates to an indoor saffron planting frame lighting fixture convenient for automatic observation and its application. Background technique [0002] Saffron (Crocus sativus L), also known as saffron and saffron, is a perennial bulbous herbaceous plant of the genus Crocus in the family Orioleaceae. It is planted in Chongming Island in Shanghai, Zhejiang, Tibet and other places in my country. Saffron filaments have high medicinal value. It reduces swelling and relieves pain, promotes blood circulation and removes stasis, nourishes blood and relieves menstrual flow, and has been clinically proven to have anti-depressant and anti-cancer effects, so it is being included in the medical insurance catalogue. As a precious spice and medicinal material, the unit price of saffron reaches 50-300 yuan / g. [0003] Saffron belongs to asexual reproduction, and its cultivation method is ...
