Description

Portable underwater lighting device {PORTABLE UNDERWATER LIGHTING DEVICE}

An embodiment of the present invention relates to a portable underwater lighting device.

In the case of ultra-high-brightness LED lighting devices (brightness of 5,000 lumens or 50W LED or more), considerable heat is generated on the back of the LED substrate, and when ultra-high-brightness LED lighting devices are manufactured as portable products, the heat generated may adversely affect the internal circuit or battery. can

Even if it is an underwater portable lighting device used in water, stable cooling is impossible because the LED module (or flash), the internal circuit, and the battery are integrally designed.

In order to improve heat dissipation characteristics of such portable lighting devices, devices for reducing heat generated from an LED light emitting module and a driving module (circuit, battery) by mounting a heat sink made of metal to a case have also been developed. This structure has a disadvantage in that the size of the metal heat sink increases for optimal heat dissipation, and accordingly, the weight increases as the size of the portable lighting device increases, and the heat sink increases even when used underwater. The weight of the portable lighting device has to be burdened.

In addition, in this case, a separate process for assembling the heat sink made of metal is required, and since a separate mold is required to manufacture the heat sink made of metal, there is a problem of increasing production cost.
