An underwater light control device

Abstract

The invention discloses an underwater illumination regulating and control device which is used for being distributed in a water area needing light. The underwater illumination regulating and control device comprises a light path device capable of floating on the water surface, a light-transmitting area is arranged on the main part of the light path device, the light path device is a concave lens or a light transmitting body with the optical property equal to that of the concave lens, the light collecting face of the light path device is upward, and the light diffusion face of the light path device is downward, so that the light path device projects light to blocked areas below and around the underwater illumination regulating and control device. The underwater light projecting range of the underwater illumination regulating and control device can be widened to dead corner areas, the needed arrangement area and number are greatly reduced, the growing space of floating plants cannot be occupied a lot, then the water purifying effect is guaranteed, manufacturing cost and use cost are relatively low, and the underwater illumination regulating and control device is suitable for being applied and popularized within in a large range.

Description

technical field [0001] The invention relates to the technical field of lighting equipment, especially an underwater lighting control device for improving underwater lighting conditions to promote ecological balance and eliminate pollution. It is mainly used for water pollution control, especially to promote the self-purification ability of natural water bodies, and secondly Used in aquaculture to increase production and reduce mortality. Background technique [0002] On April 2, 2015, the State Council issued the "Water Pollution Prevention and Control Action Plan" (i.e. "Water Ten Measures"), proposing that by 2020, the national water environment quality will be improved in stages, seriously polluted water bodies will be greatly reduced, and the level of drinking water safety guarantee will continue. The overexploitation of groundwater has been strictly controlled, the aggravation of groundwater pollution has been preliminarily curbed, the environmental quality of coastal w...

Problems solved by technology

Second, some river sections flowing through towns and some ditches, ponds and dams at the junction of urban and rural areas are generally heavily polluted, and due to organic pollution, there are many black and odorous water bodies, many people are affected, public attention is high, and dissatisfaction is high

[0017] However, according to the knowledge of optics, there will be a large dead angle area H when projecting light through the window to the underwater, resulting in a relatively limited range of projected light. For this, either increase the window area on the water area, or increase the area on the water area The number of windows, no matter which way will occupy the growth space of floating plants too much, resulting in poor water purification effect, and the required equipment is large in size and quantity, and the cost will be greatly increased
