 If you are a night fishing enthusiast, LED night fishing lights must be familiar. Let's talk about some knowledge about LED night fishing lights.

 When you can't catch a fish, there must be some problems in the above conditions. What fishermen can do is to constantly change baits and combinations. Taiwanese fishing during the day is almost the same as night fishing, except that Taiwanese fishing usually catches more than night fishing, while night fishing has more opportunities to encounter big fish. Then, the way of night fishing with light drifting, but just when the light is on, the fish will be alert, when encountering the opposite bait, want to open the mouth to eat, light has little impact on the fish. In fact, no matter yellow light, white light or blue light or purple light of LED, there is almost no difference for fish; the difference is that people have different visual perception of these lights, and people's visual perception mainly depends on the brightness (luminous flux) of light source and the chroma of light. When we talk about light, we must understand four photophysical concepts:

 The color temperature of light. When we talk about whether a light is red or white, nobody can tell. Optically, the concept of color temperature is proposed. Color temperature refers to a pure black object, which is heated all the time. The color of the object will change from black, dark red, light red, yellow, white and blue in order. Optically, it is expressed in 0000K. To be easy to remember, you can understand color temperature as the contrast between the color of light and the color of sunlight. On sunny days, the temperature of light and color under direct sunlight is about 5500K-6500K. Warm color temperature is lower than sunlight color temperature. Warm color temperature gives people a feeling of comfort, softness and safety. Therefore, families, high-end restaurants, hotels will choose warm color temperature lighting. The high color temperature is close to or higher than the sunlight color temperature. High color temperature gives a person the vision is dazzling, bright. The color temperature of light has no direct relationship with the temperature and brightness of the light source, but when people see the high color temperature, they will feel dazzling and brighter. In fact, when red light is filtered out with a color filter, the color temperature increases. Blue transparent plastic paper pasted on the headlights of many automobiles improves the color temperature, but reduces the brightness (luminous flux). The color temperature of the camera flash should be close to that of the sun. If the photograph is red, the color temperature of the camera flash is lower than that of the sun. If the photo is blue, the color temperature of the camera flash is higher than that of the sun.

  The total light energy emitted by the luminous body in the direction of 360 in unit time of luminous flux is called luminous flux, and its physical unit is lumen (Lm). The luminous flux received in a unit area is the brightness of the area, which is physically called illumination, and its physical unit is Lux (Lx). Through the light reflector (reflecting cup), all the light flux can be gathered together as far as possible, and the brightness of the irradiated area will be greatly improved. Of course, the more focused the night fishing lamp is, the better the light is.

  Colour color - refers to the new electromagnetic wave emitted by an object when it is irradiated by a certain electromagnetic wave, which absorbs and changes the electromagnetic wavelength, and enters the human vision. People who are sensitive to visible photoelectric and electromagnetic wavelengths are sensitive to color. People who are insensitive to visible photoelectric and electromagnetic waves are seriously color blind. When shopping in the mall, under the illumination of incandescent lamps with different color temperatures, the color of goods will be different from the actual color. Therefore, when choosing products based on color, they should be selected at the color temperature close to the sun.

 The percentage of the color reflected by a chromogenic object under the irradiation of a certain light wave to that reflected by natural sunlight is called the chromogenicity of light optically. In sunny days, the chroma of the halogen light source is 100%, and the chroma of the halogen light source can reach more than 95% by temperature. At present, the chroma of the general LED light source can only reach 60-65%. That is to say, under the illumination of the LED, the black and blue can hardly be distinguished.  Yellow halogen light source and LED high color temperature white light compared: in the same brightness, but the color difference. Using halogen light source to illuminate the drift, we can see more clearly, and we can almost see the number of colors on the drift. The white LED light can only illuminate the floating tail on the water surface, and it is not easy to see the color of the fish floating on the eyes.

  Watching fish drift for a long time is more likely to cause visual fatigue. Compared with blue and purple light, halogen light source naturally accumulates pyramidal cells of human eyes in dark environment. At the same time, the pupil will be enlarged as much as possible, allowing more light to enter the retina. This kind of natural adjustment of human vision is like the aperture of a camera. When the light is insufficient, the aperture of the camera is widened and the aperture of the camera is turned down when the light is bright. When fishing in blue and purple light at night, it feels bright at first. When the eyes are fully opened for a long time and the pupils are enlarged as much as possible to see the drift, it is easy to cause visual fatigue, serious dizziness, tears, which may affect vision. So it is not suitable for fishermen who often (every week) go fishing at night. Therefore, we draw the following conclusions: halogen light source night fishing lamp shortcomings: large power consumption, relatively short lighting time, so requires large battery capacity, bulky, inconvenient to carry, high cost, more expensive products. Advantages: High brightness, high chroma, long night fishing lighting, not easy to cause visual fatigue, suitable for regular (weekly) night fishing friends. Advantages of LED light source night fishing lamp: high photoelectric conversion rate, long lighting time, light weight, easy to carry, low cost, cheaper products. Suitable for fishermen who don't often go fishing at night. Disadvantage: Because of brightness and chroma, especially blue and purple lights, it is easy to cause visual fatigue, not suitable for frequent (weekly) night fishing friends. The above is just for fishermen to analyze the advantages and disadvantages of halogen light source night fishing lamp and LED light source night fishing lamp, fishermen can according to their own.
