Kyocera Corporation has developed a full-spectrum LED illuminator for aquariums. Kyocera's high-color LED illuminators combine their purple LEDs and RGB trichromatic (red/green/blue) phosphors using their own proprietary technology. It can create the effect of natural light to a specific underwater depth, can simulate the light close to the natural habitat of corals and aquatic plants, and is suitable for the growth of different aquatic organisms. Optical spectrum can also be customized to create a dark blue suitable for viewing. .
Kyocera's aquarium LED lighting launched the following four types of products in the Japanese market in mid-August:
Sea blue: Create a solar spectrum at a depth of 2.5m below sea level
Aqua Blue: Create a solar spectrum at depths of 11m below sea level
Natural white: Create a spectrum similar to the sunlight on the ground
Dark blue: suitable for viewing purposes
Product Features
1. Simulated natural light from a light bulb helps corals and aquatic plants grow
Kyocera's high-color LEDs combine a combination of purple LEDs and RGB three-primary phosphors to create light that is very close to natural light. Customized spectra can be used to create light that is close to the natural habitat of corals and aquatic plants at specific underwater depths. .
In addition, each LED component emits full-spectrum light close to natural light, creating a uniform brightness with no color separation, suitable for long-term growth of corals and other marine life.
2. High output
Kyocera's self-developed ceramic technology enables the LED lamp to achieve superior durability. In addition, the air cooling function is realized by air convection, which can achieve both high color rendering and high output. Kyocera has considered the scene used at the seaside. , using natural air cooling to dissipate heat, without using a fan that is prone to failure, thus minimizing the occurrence of failure.

'The ability of corals to grow normally depends largely on the health status of the symbiotic algae of zooxanthellae. The zooxanthella provides the corals with the organic matter necessary for their growth through photosynthesis. The light determines the photosynthesis effect of zooxanthellae. Very important environmental factors, therefore, play an important role in the health of corals. At Shizuoka University, we did an experiment to test the effects of light on coral growth: using a 24 ° C aquarium, at 400 μm cm Kyocera natural white LED (KNW) and conventional LED (CLED) were used to detect the abundance of zooxanthellae and its photosynthetic pigments (chlorophyll a and polydatin) at -2 sec-1. Two coral species, finger-shaped rose coral and axial coral, lasted for 2 months. The results showed that the corals cultivated under KNW kept their primary colors unchanged, while the corals cultivated under CLEDs began to fade after 2 months. From the final data, the density of zooxanthellae is 32% for CLED lamps and 47% for KNW lamps. For chlorophyll a, 17% for CLED lamps and 44% for KNW lamps. The CLED lamp is 26% and the KNW lamp is up to 125%. This result clearly shows that due to the light and natural light KNW high level of similarity, it is ideal for long-term growth of coral. There is also expected to achieve new results in the study of physiological responses of coral bleaching and coral KNW problems by using the lights. '

'According to the Minamata Convention on Mercury signed in 2013, we will limit the production and import of mercury products from 2020, so we are always looking for high-quality light sources to replace metal halide lamps, which is not easy because Many marine organisms could not grow well under ordinary LED lighting. At this time, we found Kyocera's LED lighting and tried to use it for the cultivation experiment of alfalfa, which finally achieved good results. It is expected that Kyocera's LED lights will greatly reduce energy consumption, and at the same time create a good environment for marine life.
