摘要： The present invention relates to an underwater photographic lighting device which comprises: a flashlight body fully sealed by a seal, the interior of the flashlight body is provided with waterproof through holes, the flashlight body is respectively connected to a lamp head and a flashlight via conductive connecting cables, the lamp head is sealed by a seal, and connecting parts can be respectively dismounted from the flashlight body; and a power supply component sealed by a seal and connected to the flashlight body. Every part of the underwater photographic lighting device of the present invention is sealed, so the waterproof function is better; and each part is independent, and therefore can be optionally replaced and maintained. The battery module can be replaced and upgraded according to future need, and can be independently charged, so that the life cycle of the whole device is extended. When a beam head is used for photographing, a reflection cup and a condensing lens that are added on the beam head can increase light efficiency, so that a better photographing and recording effect can be achieved. In addition, since the device can be connected to a camera or a camcorder without a grip, a clamp or other parts, the device is convenient, light in weight and practical.
