Natural light: Sunlight is a very familiar source of light for fish and plants, and is a more natural way of lighting. For the aquarium engineering museum, although sunlight is a low-cost light source, the indoor solar light is not very stable and is very difficult to control. Therefore, an artificial light source must be used instead. Sunlight is rarely used as the primary source of illumination for aquariums, but can be used as an auxiliary light.

Light efficiency: The resulting illuminance is too low compared to the input energy. As the bulb wattage increases. Its power is also rising. When using it, the effects of these thermal energy on the cylinder must be considered. Since the bulb will generate high temperatures, if it is caught in the water in the tank, it may cause the bulb to rupture. In fact, both the illumination and the optical frequency of the light will decay. Even if the person's eyes cannot be distinguished, it does not mean that other creatures cannot be distinguished or will not be affected.

Sterilization lamp: There is usually such a thing in marine aquaculture equipment, but as the name suggests, his main function is to purify the water and remove the bacteria that affect the health of the fish in the sea, instead of acting as lighting.

The light transmittance is over 92%, and the acrylic board colored with dye has a good color development effect. In addition, the acrylic sheet has excellent weather resistance, high surface hardness and surface gloss, and good high temperature resistance. . Acrylic sheets have good processing properties and can be divided into casting type and extrusion type according to the production process. Both thermoforming (including molding, blow molding, and vacuum blistering) can be used, as well as mechanical processing such as drilling, turning, washing, cutting, and the like. Micro-computer controlled mechanical cutting and engraving not only greatly improve the processing accuracy, but also create more beautiful patterns and shapes than the traditional way. In addition, the acrylic sheet can be laser-cut and laser-engraved to produce strange products.
