Abstract

The invention discloses an underwater lighting device. The underwater lighting device comprises a glass lens, a light emitting diode, a light emitting diode driving circuit, a lamp housing, a bottom cover, a flexible circuit board and a diamond-like carbon film coating, wherein the lamp housing is matched with the glass lens and a bottom cover to form a closed space; the light emitting diode is arranged in the closed space and corresponds to the glass lens, so that light of the light emitting diode can transmit through the glass lens; the inner wall of the lamp housing is provided with the diamond-like film coating; the flexible circuit board is arranged on the diamond-like film coating; the light emitting diode driving circuit is connected to the flexible circuit board and connected withthe light emitting diode. According to the underwater lighting device provided by the invention, the light emitting diode driving circuit is printed on the flexible circuit board, so that the space utilization rate of an inner cavity of the lamp housing is improved; the diamond-like film coating is arranged on the inner wall of the casing, so that the heat conduction performance of the casing is improved, and further the heat dissipation efficiency is further improved.

Description

technical field [0001] The invention relates to the technical field of underwater lighting, in particular to an underwater lighting device. Background technique [0002] Traditional underwater lighting generally adopts a cylindrical lamp housing mechanism, and the interior is mostly multi-layered with a small circular PCB (Printed Circuit Board, printed circuit board). In a limited space, the circuit is placed as much as possible according to the lighting requirements, and the output power is large. The arrangement of components is too compact, which generates a lot of heat, and the absorption and scattering of light by seawater is very large. The light below 1000 meters in seawater cannot penetrate, so high-power LED lights are needed for lighting, and a large amount of light will be generated if the power is high. Heat, and due to the limited space, the electronic components are tightly arranged and heat generation is increased. There is air in the lamp cavity, and the the...
