Detailed Description
To further illustrate the technical means and effects of the present invention for achieving the intended purpose, the following detailed description will be given to an LED fish gathering lamp with variable gathering depth according to the present invention, with reference to the accompanying drawings and preferred embodiments.
In the description of the present invention, it should be noted that the terms "upper", "lower", "left", "right", and the like indicate orientations or positional relationships based on the drawings, and are only for convenience of describing the present invention and simplifying the description, but do not indicate or imply that the referred device or element must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention.
Referring to fig. 1, the LED fish gathering lamp with variable gathering depth comprises a single chip microcomputer, a PCB, and white LEDs and cyan LEDs alternately positioned on the PCB, wherein the single chip microcomputer is used for controlling driving currents of the white LEDs and the cyan LEDs, so that the white LEDs and the cyan LEDs achieve different spectral energy distributions and further achieve different lumen output ratios, and the color temperature and the brightness of the LED fish gathering lamp can be adjusted according to different types of caught fish through the single chip microcomputer.
In order to achieve a better fish gathering effect, the invention selects white LEDs with the color temperature of 2700-4000K and the color rendering index CRI of 65-90 and selects cyan LEDs with the wavelength of 490-510 nm, the brightness ratio of the white LEDs to the cyan LEDs is 5: 1-7: 1, and the energy of light with the wavelength of 470-500 nm in mixed light formed by the white light and the cyan light accounts for about 7-10% of the total energy of the mixed light.
Taking the squid catching as an example:
referring to fig. 2, since the light attenuation in seawater mainly comes from absorption and scattering, there is a wavelength range (450 nm-550 nm) where the light attenuation factor is the lowest, called "underwater window", and in addition, the sensitivity of the squid retina in various economic fishes, especially in cephalopoda, to light, and it can be seen from fig. 2 that the wavelength of light to which the squid is most sensitive is about 490nm under the dark condition. Generally, fish will leave when the light is too high or too low. The fish tend to gather in a range of suitable illumination, and when the illumination can be adjusted in a larger range, more fish schools can gather; therefore, the illumination level is adjusted by controlling the energy of the lamp power supply through the single chip microcomputer, so that fishes can be accumulated in seawater at different depths, and the fishing is easy.
In view of the above factors, it can be known from fig. 3 that the light with the wavelength of 490nm to 510nm in fig. 3 is in the overlapping region, and the wavelength of 490nm to 510nm is about the most sensitive range of squid and the lowest light attenuation region in seawater; therefore, in order to capture squid better, in the embodiment, a white LED with a color temperature of 3500K and a color rendering index CRI of 70 is selected as the first light source, and a cyan LED with a wavelength of 490nm to 510nm is selected as the second light source, wherein the luminance ratio of the white LED to the cyan LED is 6:1, so as to make up for the deficiency of the white LED at the wavelength.
In the LED fish gathering lamp of this embodiment, in the mixed light formed by mixing the white light and the cyan light, the percentage of the energy of the light with the wavelength of 470nm to 500nm to all the energy after mixing the white light and the cyan light (i.e. the total energy of the light with the wavelength of 380 and 780nm after mixing the white light and the cyan light, please refer to fig. 4) is about 7.3%, please refer to table 1 and fig. 4, the energy ratio of the light with the wavelength of 470nm to 500nm in the fish gathering lamp of this embodiment is greater than the energy ratio of the metal halide fish gathering lamp (the energy ratio of the metal halide fish gathering lamp is 7.2%); when the squid is used as a main target fish school, the visual sensitivity range is 470nm-500 nm. In this wavelength range, the energy percentage of the LED 3500K is lower than that of the metal halide lamp, and the energy percentage of the metal halide lamp is lower than that of the mixed white and cyan LEDs with the brightness ratio of 6:1 in this embodiment, and in addition, although the maximum energy can be obtained by using a single cyan LED or other single color LEDs (blue or green) as the illumination light source in the squid vision sensitivity range, the most sensitive does not mean that fish is the most favored, and the mixed effect of multiple illumination elements still needs to be considered, so the LED fish gathering lamp in this embodiment can achieve the maximum photoelectric efficiency and penetration depth, save energy than the metal halide fish gathering lamp, and can attract squid better.

TABLE 1
TABLE 2
In other embodiments of the present invention, the energy ratio of the 3500K white LED and cyan LED mixed light (the luminance ratio of the white LED to the cyan LED is 6:1) at different wavelengths can be adjusted by the single chip microcomputer, so as to capture different fishes, see table 2, for example, a green light region of 520nm to 550nm can be used to capture most fishes such as squid; photo-etching in yellow light region of 580-610 nm is used for catching sardines. When the fish catching device is used, the brightness ratio of the white LED and the cyan LED is adjusted through the single chip microcomputer, and therefore the catching requirements of different kinds of fish are met.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention in any way, and any simple modification, equivalent change and modification made by those skilled in the art according to the technical spirit of the present invention are still within the technical scope of the present invention without departing from the technical scope of the present invention.
