Description

Modular underwater light device

The present invention relates to an underwater light, in particular to a modular underwater light device.

Underwater lights can emit light under the water, and can be used as fish-collecting lights. If the frequency changes such as flickering and blinking are added, they can also be used for underwater instructions. The former uses the phototaxis of fish to attract fishes approaching through underwater light sources. In order to increase the fishing equipment, the early fish collection lamps used tungsten or halogen bulbs, but these bulbs have a short life and are prone to failure. What's more important is that the wavelength of their light is not easy to penetrate in water. Replaced by light-emitting diodes (LEDs) that are small, durable and penetrating.

Referring to FIG. 1, a conventional underwater lamp 1 includes a heat sink 11 with a plurality of card slots 110 formed on an outer surface thereof, a plurality of circuit boards 12 latched in the card slots 110, and a plurality of the circuit boards 12 disposed in the circuits. A light-emitting diode 13 on the board 12, a light-transmitting casing 14 surrounding the heat-dissipating base 11 and the light-emitting diodes 13, a top cover 15 disposed on the top of the light-transmitting casing 14, and a The bottom cover 16 at the bottom of the transparent casing 14. Each clamping groove 110 extends in the up-down direction, so that the light-emitting diodes 13 on each circuit board 12 are arranged in a vertical row in the up-down direction, however, the light-emitting diodes 13 are fixed to the circuits. On the board 12, when one of the light-emitting diodes 13 is broken, the entire circuit board 12 must be removed for maintenance, which is very inconvenient, and the underwater light 1 cannot correspond to different depths or different types of fish schools to instantly change different wavelengths or The number of light-emitting diodes 13 is such that it is necessary to manufacture underwater lights 1 configured with light-emitting diodes 13 of different numbers or wavelengths, resulting in increased cost and occupying a lot of storage space.

Therefore, an object of the present invention is to provide a modular underwater light device.

Therefore, the modular underwater light device of the present invention includes a housing cover made of a light-transmissive material and surrounding an accommodation space, an inner frame, and a plurality of light sources detachably disposed on the inner frame.
