Gids voor LED-vissen die lichten aantrekken: technologie en selectie

Have you ever seen fishermen using fish attracting lights on their boats? These magical bulbs aren’t for lighting—they’re for attracting fish! Fish attracting lights take advantage of fish’s phototaxis, making it easier for fishermen to catch them. Fish attracting lights not only make fishing more efficient but also protect the environment and fishermen’s health, truly a perfect blend of technology and tradition.

LED fish attracting lights, as a unique lighting device, have been widely adopted in the fishing industry. As a crucial component of LED fish attracting lights, the quality and performance of the lights directly impact the overall effectiveness and lifespan of the lighting system. This article will explore the working principles of LED fish attracting light power supplies, key considerations for selection, and maintenance and care aspects.

What are the types of fish-attracting lights?

By simulating the bioluminescence characteristics of plankton using specific spectra (such as blue and red light combinations), these lights attract phototactic fish to gather. Modern fish-attracting lights widely adopt LED technology, featuring an IP68 waterproof rating, intelligent temperature control, and multi-spectrum adjustment functions, with power ranging from 15W portable models to 3000W offshore models.

I. Classification by spectral characteristics

‌Blue light (450-495 nm): Offers the strongest penetration, is suitable for deep-water operations (50 meters or deeper), and is highly effective for mid-to-upper layer fish such as sardines and mackerel. Luminous efficacy can reach 100-110 LM/W, making it the mainstream option in the market.

‌Yellow light (570-590 nm): A dedicated attraction wavelength for squid, performing exceptionally well in turbid waters. Combined with a 360° light emission angle, it can cover a larger area.

‌Green light (495-570 nm): Matches the fluorescent characteristics of plankton, attracting fish through the food chain effect.

‌Red light (620-750 nm): Used for shallow-water fish attraction, but has high water absorption and limited penetration depth.

‌RGB combination light‌: Integrates red, blue, and green chips to simulate moonlight or bioluminescence (e.g., krill), enhancing attraction to higher-order fish. For example, the blue-green combination spectrum improves soft-bodied fish aggregation efficiency by 40%.

‌Pulse strobe mode‌: Supports 200 Hz high-frequency flashing to enhance visual stimulation intensity.

II. Classification by installation scenario

‌Surface fish aggregation lights: Installed on ship sides or masts to illuminate the water surface and create a light zone. Wide-angle lenses, with a beam angle of 120°, are necessary to enhance the coverage, and they emit light that surpasses 5,000 lumens. The drawback is that the light is affected by sea surface reflection, resulting in weaker penetration in deep water compared to underwater lights.

‌Underwater fish aggregation lights: IP68 protection rating, capable of withstanding pressure at 50 meters water depth (approximately 5 ATM). The aluminum housing combined with a nylon heat dissipation structure resists salt corrosion. Typically employs a dual-mode heat dissipation system with copper fins and a seawater circulation channel to maintain an operating temperature ≤85°C, with annual light decay <3%.

Fish aggregation lights are typically suspended around fishing vessels for large-scale deployment, can be fixed to deck or dock surfaces for high stability, or quickly installed using clamps for enhanced flexibility.

How Fish Attracting Lights Work

The core technology of fish-attracting lights is to use the physical properties of light to attract fish. At night, it emits light rich in the blue spectrum through high-intensity LED lights. This type of light can penetrate seawater to the greatest extent, directly illuminating fish in the deep sea. In dark waters, light serves as an important reference point for fish. Fish in the water are stimulated by the light and gather near the light source, making it easier for fishermen to catch them.

Utilizing the phototaxis effect, the retinas of mid-to-upper layer fish (such as sardines and mackerel) are sensitive to specific wavelength bands. Blue-green light stimulates their cone cells, triggering phototaxis-driven clustering behavior; additionally, by exploiting the food chain cascade effect, LED lights emit ultraviolet light (365-420 nm) and blue light to attract plankton, which in turn attract small fish to follow the plankton into the illuminated area, thereby drawing larger predatory fish to follow the small fish schools.

Therefore, blue or green light sources are commonly used in fish-attracting lights because these colors travel farther in water and have a stronger attraction to fish. Thus, using blue or green light sources can more effectively attract fish and improve fishing efficiency.

Target fish species such as squid and mackerel are sensitive to specific wavelength ranges of light (e.g., squid are most easily attracted by blue light in the 450-490 nm range). They mistakenly identify areas of intense light as safe environments or food sources and actively approach the light source.

Additionally, some fish-attracting lights emit certain sound waves that can propagate through water, alerting fish and making them more easily attracted by the light.

How to choose the right fish-attracting light?

Fish-attracting lights come in various colors, including blue, green, and yellow light, among others. Selecting the appropriate fish-attracting light requires considering the phototaxis characteristics of target fish species, operational water depth, and environmental factors. The following is a scientific selection guide:

Deep-sea operations >40 meters: Blue/green light with a wavelength of 450-560 nm, offering strong penetration capabilities, suitable for deep-sea operations exceeding 40 meters in depth, attracting mid-to-lower layer fish species; 300W green LED underwater illumination can reach a maximum depth of 85 meters. Target fish species such as squid and mackerel are sensitive to specific wavelength ranges of light (e.g., squid are most easily attracted by blue light in the 450-490 nm range), mistakenly identifying areas of intense light as safe environments or food sources and actively approaching the light source.

Shallow-water operations (<40 meters): Red light with a wavelength of 620-750 nm has a longer irradiation distance in shallow-water areas (<40 meters) and is commonly used for mackerel fishing and the final stages of net enclosure operations; ‌Yellow light (2700K-3000K): With a long irradiation distance, it is suitable for shallow sea areas such as the South China Sea and Southeast Asia and is often used in combination with green light (at a ratio of 20%-50%).

‌White light (4200K and above): Highly versatile, it is commonly used in deep-sea operations in combination with high color temperature (5000K-6500K) and green light to enhance effectiveness.

Fish Species and Optimal Light Color Selection List

Opmerkingen: Carp and crucian carp have strong tolerance to blue light. Although ultraviolet light enhances float signals, it is harmful to the eyes, and the technology is not yet mature, so it is not recommended at this time. White light is only suitable for auxiliary lighting; direct illumination may disperse bottom-dwelling fish. Ultraviolet light has significant radiation hazards, and light decay control is challenging, so it has not yet been commercialized.

Deep-sea fishing vessels are recommended to use a combination of blue light and high-color-temperature white light for lighting to expand the coverage of the phototactic zone. Shallow-water operations should use a yellow-green light combination to balance penetration power and fish aggregation efficiency. LED light sources should be prioritized: they consume only one-third of the power of metal halide lamps and pose no UV radiation risks.

What is the typical lifespan of an LED fish-attracting light?

The lifespan of an LED fish-attracting light is significantly influenced by technical specifications, usage environment, and maintenance conditions. The theoretical lifespan of mainstream products and their actual performance are compared as follows: Most professional-grade LED fish-attracting lights are rated for a lifespan of 50,000 hours (e.g., a 1200W green-light underwater light). The 50,000 hours mentioned here refers to the point where the light output has decayed to 70% of its initial value (L70 standard), at which point the light can still function, but its fish-attracting efficiency decreases.

Factors affecting the lifespan of fish-attracting lights:

• ‌Inadequate heat dissipation design: Poorly designed lights with inadequate heat dissipation may experience doubled light decay rates, leading to faster LED decay and a shorter lifespan; Deep-water lights (IP68) using copper fins and seawater circulation cooling maintain sufficient heat dissipation, keeping annual light decay below 3%, with a lifespan closer to the theoretical 50,000-hour value.

• ‌Poor voltage/current stability: Overvoltage operation or unstable current can severely damage the LED chips, causing the lifespan to plummet to 1,000 hours.

• Environmental corrosion: Products exposed to high-salt, high-temperature marine environments for extended periods experience a 30%-50% reduction in lifespan.

• Driver failure: Accounts for 80% of lighting fixture failures; low-quality power supplies have a lifespan of only 20,000 hours;

• Mechanical damage: Wave impact or installation collisions can damage the sealed structure;

• Spectral overload: Operating at excessive power to enhance fish attraction accelerates chip aging.

Key measures to extend lifespan:

• Prioritize deep-water models with IP68 protection and copper substrate heat dissipation design;
• Avoid frequent on/off cycles (≤5 times per day) to reduce driver circuit wear;
• Clean salt deposits from the lamp surface quarterly to maintain heat dissipation efficiency;
• Install waterproof junction boxes in humid environments to isolate salt fog corrosion.

Under proper usage conditions, the actual lifespan of professional LED fish-attracting lights is 4–10 years, far exceeding that of traditional metal halide lamps (approximately 1 year). However, be wary of misleading specifications in low-cost products—some merchants claim a “100,000-hour lifespan,” which refers to the theoretical lifespan of the LED chip, not the entire lamp.
