Preferably, in described LED guard rail lamp, also comprise:

Guardrail pipe, one side opening, the edge of described cover is fixedly connected with described guardrail pipe and closes described opening to form the second confined space, wherein, the arc diameter of the cross section of described cover is identical with described guardrail pipe diameter, and the below of described radiator is fixed on the opposite side of described guardrail pipe inwall by a U-shaped fixture is positioned at described second confined space;

Lens, it is arranged on described radiator, and described lens are positioned at described first confined space;

Trim, it is arranged on described lens;

LED chip, it is arranged on described radiator, and described LED chip is in the below of described lens.

Preferably, in described LED guard rail lamp, described airtight bar is the airtight bar of foamed silica gel.

Preferably, in described LED guard rail lamp, described trim and radiator are aluminium section bar, lightweight, and heat conduction, electric conductivity are excellent, and surface is attractive in appearance after peroxidating and plastic-blasting, anticorrosive.

Compared with prior art, the beneficial effects of the utility model are: make translucent cover be pressed in groove on radiator by the extruding of cover, form the first confined space.High temperature resistant, anti-aging, seal and the durability of being out of shape the performance enhancement such as little first confined space that the airtight bar of foamed silica gel on the one hand in groove is fabulous; Described hold down gag makes the two-port of translucent cover firmly be pressed in groove on the other hand, avoids causing owing to expanding with heat and contract with cold interior pressure to be greater than external pressure, causes airtight bar to ftracture, thus effectively prevent airtight inefficacy.Second confined space is the LED guardrail tube integrally closed structure that the edge of described cover and the two ends of guardrail pipe are fixedly connected to form.Above-mentioned dual confined space serves good waterproof and dustproof effect, makes the electrical property of LED guard rail lamp, the use of optical property is protected, effectively ensure that its service life.
