A ladder with the function of turning on and off when entering the water

Abstract

The invention discloses a ladder with functions of automatically illuminating underwater and extinguishing out of water. The ladder comprises a plurality of ladder sections, each ladder section comprises two handrail portions and a step portion connected with the two handrail portions, and at least one LED (light emitting diode) lamp component is mounted on at least one ladder section for underwater application. Each LED lamp component comprises a closed shell, an LED lamp and a control circuit with two break contacts, wherein the LED lamp is positioned in the shell, the two break contacts penetrates the shell and are hermetically fixed to the shell, and after the two break contacts are connected through a conductor, the control circuit and the LED lamp form a loop to light on the LED lamp. By mounting of the LED lamps, with functions of automatically illuminating underwater and extinguishing out of water, on the ladder sections for underwater application, the ladder sections automatically illuminate when entering water to provide light for users, so that the users can conveniently find the underwater ladder sections to accurately step on the step portions; after the ladder is withdrawn when not used, the ladder sections automatically extinguish, so that electric energy is saved, and service time is prolonged.

Description

technical field [0001] The invention relates to a ladder, in particular to a ladder with the function of automatically turning off the lights when entering and exiting water. Background technique [0002] Some places that are suspended from top to bottom, such as boats and yachts, are usually equipped with fixed escalators or telescopic escalators for the convenience of diving, swimming or work. When the fixed escalators or telescopic escalators are opened, there will be some steps Submerged into the water, like this, at night or under the dark occasion of light, it is inconvenient for the personnel to find the ladder, and it is impossible to find the stepping part of the ladder section, which brings a lot of inconvenience. Contents of the invention [0003] In order to solve the above technical problems, the present invention proposes a ladder with the function of automatically turning off the water when it enters and exits the water. By installing an LED light on the lad...
