Application of Underwater Disinfection Light PCB in Home Aquarium

        As people’s quality of life continues to improve, more and more households begin to raise ornamental fish, and home aquariums have become a popular choice for home decoration and leisure. However, maintaining water quality in aquariums has long been a challenge for fish enthusiasts. Excessive growth of bacteria and algae in the water not only affects water quality but also threaten the health of the fish. The emergence of underwater disinfection light PCBs offers a new solution to this problem. With their efficient sterilization capabilities and precise control performance, they show great application potential in the home aquarium filed.

 

1. Working Principle of Underwater Disinfection Light PCB

Underwater disinfection light PCBs are primarily equipped with ultraviolet (UV) light tubes or LED light beads, and use specialized circuit designs to drive and control the light source. Ultraviolet light can destroy the DNA or RNA structures of bacteria, viruses, and algae cells, rendering them incapable of reproduction or survival, thereby achieving sterilization and inhibiting algae growth.

 

 

As the core carrier, the underwater disinfection light PCB performs functions such as power conversion, current regulation, light intensity control, and safety protection. For instance, constant current drive circuits ensure stable current output during UV light operation, preventing voltage fluctuations from affecting sterilization efficacy. Simultaneously, integrated over-voltage and over-current protection modules in the circuit can automatically cut off the power supply under abnormal conditions, ensuring the safety of both equipment and users.

 

 

2. Advantages in Home Aquarium Applications

1) Efficient Sterilization and Water Purification

Compared to traditional chemical disinfection methods, underwater disinfection light PCBs can rapidly eliminate harmful microorganisms in the water without leaving chemical residues, posing no toxic risk to fish or aquatic plants. For example, UV irradiation can rapidly inactivate common pathogens such as water mold and Ichthyophthirius multifiliis (the parasite responsible for white spot disease), effectively preventing fish diseases and helping maintain ecological balance within the aquarium.

 

 

2) Precise Control and Energy Saving

Underwater disinfection light PCBs typically feature intelligent control functions,enabling users to flexibly adjust the operating time and intensity based on aquarium size, fish population, and water quality. For example, setting a timer for the disinfection light to operate 2–4 hours per day can effectively meet sterilization needs while minimizing energy consumption. Moreover, the application of UV LED lights further enhances energy utilization efficiency, achieving 30%–50% lower energy consumption compared to traditional UV light tubes.

 

 

3) Easy Installation and Aesthetics

Underwater disinfection light PCBs feature a compact design, making them easy to integrate into various types of aquarium filtration systems or lighting fixtures. Installation is simple and requires no significant modifications to the aquarium. Some products also utilize waterproof and corrosion-resistant materials, enabling long-term underwater operation without compromising the aquarium’s overall aesthetics, while adding a touch of technological sophistication to home decor.

3 Dispensing Paths for Dispensing Technology

图片
       PCB are sometimes processed by dispensing machines, which are mainly used for waterproof, dustproof, anticorrosion, and long-term effective protection of PCB and some electronic components that are sensitive to some electronic equipment. In the dispensing process, there are 3 dispensing paths. Do you know which 3 are?   1.  I-shaped Distribution Path The I-shaped dispensing path, also known as the straight-line dispensing path, is suitable for dispensing where a small area is required at the edge of the chip. The length of the dispensing route is generally 50% to 125% of the edge length of the chip. Longer lines can help reduce the curing time of the glue at the edge of the chip, but increase the possibility of trapping some air bubbles, so care needs to be taken to control the amount of glue used.     2.  L-shaped  D ispensing  P ath The L-shaped dispensing path is dispensing along the adjacent two sides of the chip. The glu...

The Difference between PCB Dry Film and Wet Film

Both the dry film and the wet film of the PCB refer to the raw materials used for the Circuit. The dry film is a kind of high-molecular compound. It generates a polymerization reaction after being irradiated with ultraviolet rays to form a stable substance attached to the surface of the plate, thereby achieving the functions of impedance plating and etching. The wet film is a blue viscous liquid synthesized from a photosensitive resin and is added with a sensitizer, a pigment, a filler, and a solvent. The functions of the dry film and the wet film are basically similar. However, if the surface of the PCB is not flat and a very thin film thickness is required, the PCB manufacturers can consider using a wet film. Moreover, the cost of the wet film is much lower than that of the dry film, so that a large amount of cost can be saved. The wet film has a good filling ability, but does not protective film,  so high exposure energy is required. If it is a perforated PCB, the dry fil...

The Difference between PCB and PWB

　　In our daily life, we often use electronic products. A lot of electronic components are used in each electronic product, so we often hear the words PCB and PWB. They are similar but different from the literal point of view, therefore many people are confused. They are not clear whether the PCB and the PWB are the same. Let's explain in detail. 　　The difference between PCB and PWB : 　　PCB: Based on insulating substrate, it means a kind of products on which the wires are connected and components are printed from point to point on a dielectric substrate in a predetermined design. It is the English abbreviation of Printed Circuit Board. 　　PWB:Based on insulating substrate, it means a kind of products on which the wires are connected from point to point on a dielectric substrate in a predetermined design. However, there is no printed component on it.PWBs are the early name of the British, because at that time there were only circuit diagrams on the circuit board, but no printe...
