Aquarium illuminating system

Abstract

The invention provides a control system of an aquarium illuminating system, wherein a motor driver changes the relative inclination degrees of light sources related to ornaments in an aquarium with the passage of time, so that incident light falling onto the ornaments more accurately simulates natural light of the sun which moves every day and moves seasonally. Besides relative change of the inclination degrees, the power setting of the light sources can be further adjusted so as to further simulate the effect caused by changes of climates and / or weather every day. Therefore, the system eliminates regions filled with excessive light (the light further can promote growth of unnecessary algae) from the light sources erected in a single fixed position in the aquarium, and saturation of the excessive light means that light from the light sources in the single fixed position penetrates downward into the deep part of the aquarium. By providing the system which effectively changes the angle of incidence of light, a programmable illuminating level can be obtained in the outward regions of ornaments or the regions below bumps, which can not be realized by the erected light sources in the single fixed position.

Description

technical field [0001] The present invention relates to a lighting system for an aquarium, aquarium or other tank suitable for containing organic life. For simplicity, such tanks are collectively referred to as "aquariums" in this specification. Background technique [0002] Fluorescent tube lighting has always been a stable lighting effect in the aquarium, and the fluorescent tube lighting is usually in the form of multiple light tubes, which are longitudinally fixed in the cover of the aquarium. [0003] Recently, LED-based smart lights such as the L1000 Smart lights (LEDs) that allow the sunrise, daylight, sunset and moonlight cycles to repeat automatically over a 24-hour period. in the In the system, LED lights are mounted in a flat / flat array on a circuit board in the aquarium lid, with white and blue light, providing direct downward incident illumination to the bottom of the aquarium. As can be understood, the high-intensity diffused light source provided by thes...

Problems solved by technology

[0007] However, since light penetration is power dependent, these existing systems (in full daylight conditions) can produce excessive light levels to the top of the aquarium (especially in an attempt to provide the necessary light for the crevices) and because of the water column Insufficient light levels at the bottom of the trough due to scattering and attenuation effects

In fact, the limited (time-varying) microcontroller control exercised in newer aquarium lighting systems is actually insufficient and really only provides an aesthetic consideration for the human viewer, not for the animals in the aquarium Or the consideration that fish provide natural environmental conditions

Additionally, unnecessarily high light levels can promote unwanted algae growth, which is unsightly and detrimental to viewing opportunities at best

In fact, in the case of fish tanks, too much light or not enough light can have adverse effects on aquatic life
