IMPROVED LANS FOR EXPLOSION PROOF LED LAMP AND EXPLOSION PROOF LED LAMP USING THE SAME

摘要

The purpose of the present invention is to provide an improved lens for an explosion-proof LED lamp and the explosion-proof LED lamp using the same, capable of providing an efficient lighting system on a narrow ship by reducing the number of lighting devices to be installed by improving luminous efficiency and the uniformity ratio of illuminance on a work surface by increasing a light distribution angle. The present invention includes: a lens body part which has a plane shape; and a groove part which is formed on the lens body part with a preset space. The groove part is formed with a conic shape. The improved lens for the explosion-proof LED lamp according to the present invention improves the luminous efficiency and the uniformity ratio of illuminance on the work surface by increasing the light distribution angle and reduces installation, maintenance, and repair costs by reducing the number of the lighting devices to be installed. The explosion-proof LED lamp using the improved lens for the explosion-proof LED lamp according to the present invention provides the efficient lighting system on the narrow ship.
