Example Embodiment

[0018] The present invention will be further explained below in conjunction with the drawings.

[0019] In view of the characteristics of the absorption spectrum of seawater, the present invention selects the color cast LED lamp with relatively less blue and green light and relatively more light in the rest of the spectrum as the light source, so that the light emitted by the light source reaches the irradiated object after the seawater absorbs the non-blue-green spectrum. The spectral gain of the light wave on the surface is close to the natural spectrum. It is suitable for deep-sea lighting, and its pressure resistance, thermal conductivity, and corrosion resistance can meet actual needs. It can be used in marine surveys, diving entertainment, biological detection and other fields

[0020] Such as figure 1 As shown, the LED spectrum adaptable submarine light mainly includes a lens 1, a lamp holder 2, a sealing ring groove 3, an LED reflector 4, an LED panel light 5, a connecting...

Abstract

The invention relates to an LED frequency spectrum adaptation underwater lamp. The LED frequency spectrum adaptation underwater lamp comprises a lens, a lamp base, an LED lamp panel and a light reflecting cup matched with the LED lamp panel; the lens is fixed to the lamp base, and the lamp base is composed of an upper portion and a lower portion; each of the upper portion and the lower portion is provided with eight connecting screw holes, and the upper portion and the lower portion are fixed through screws; the light reflecting cup and the LED lamp panel are meshed together through hole groove openings; the LED lamp panel is fixed to a table board on the lower portion of an inner cavity of the lamp base; and two O-shaped sealing ring grooves are formed in the upper portion of the inner cavity of the lamp base, and a preserved fixed screw hole and a power source plug interface are arranged at the bottom of the lamp base. High-power LEDs are adopted as a light source, and the lamp has the higher penetrating power under the water; the light energy utilization rate is improved; the component and the concentration of trace elements doped in LEDs are adjusted to achieve aim of frequency spectrum adjustment; gain of light absorbed by sea water is equalized within the limit of visible spectrum.

Description

technical field [0001] The invention belongs to the field of optoelectronic technology, and relates to an LED spectrum adaptable submarine lamp. Background technique [0002] The ocean covers 71% of the earth's surface, and the development of human society is increasingly dependent on the ocean. The attenuation of the sun's rays in seawater is thousands of times greater than that in the air, and the light intensity of the ocean surface and the depth of the ocean differ greatly. Usually, sunlight can only reach the depth of a few meters or tens of meters underwater, so good artificial lighting becomes especially important. However, the underwater lamps currently on the domestic market are generally only suitable for a depth of less than 500 meters, and the maximum power is only a few watts to tens of watts, and the underwater penetration effect is poor. At the same time, the diffusion and attenuation coefficients of electromagnetic waves of different wavelengths in seawater...
