Metal halide(MH) lights are a subset of HID lights. Generally, an abundant amount of light in the blue spectrum is produced by MH bulbs, as shown inFig. 9.5. Blue light promotes plant growth and is excellent for green leafy growth and keeping plants compact. They also contain some ultravi...
PURPOSE:To improve the light emission efficiency and to lower the color temperature by encapsulating plural metal halides having specific light emission spectrum while providing specific reflection film. CONSTITUTION:Metal halide having strong light emission spectrum in the infrared region or the ultra-...
Metal Halide light produces an intense light of a blue-white spectrum excellent for vegetative plant growth. Geraniums, marigolds, mums, zinnias, and violets all thrive under Metal Halide light, as do most vegetables. A plant grown under a halide light will often exhibit increased leaf growth,...

FIELD: electrical engineering; mercury-free metal-halide lamps for plant photoculture. SUBSTANCE: lamp has torch made of optically transparent material that accommodates hermetically sealed electrodes and is filled with inert gas and halides radiating in green spectrum of metal. Use is made of dopes...
Metal halide perovskite has emerged as a promising material for light-emitting diodes. In the past, the performance of devices has been improved mainly by optimizing the active and charge injection layers. However, the large refractive index difference among different materials limits the overall light...
The light-soaking effect is the observation that under constant illumination the measured power conversion efficiency of certain solar cells changes as a function of time. The theory of the light-soaking in metal halide perovskites is at present incomple
A Metal Halide Lamp has very different characteristics in that, the spectrum of illumination can be varied by varying the mixture of Metal Halide generated in the lamp. For these lamps, we have improved the electrode, the chemical composition of the Metal Halide, and the glass envelope. We ...
CERAMIC METAL HALIDE Lamps Growlite CMH horticulture lamps were designed with plants in mind. The spectrum provides a very broad range of light with a perfect ratio of blue to red and far red light very closely mimicking natural sunlight. ...
In this paper, a new control method is presented to reduce acoustic resonance phenomena of metal halide lamps with electronic ballasts. A behavior of frequency controlled resonant inverter is analyzed and the transfer function is obtained. An integrator as a current controller for ballast is employed...
