Detailed ways

In order to make the objectives, technical solutions and beneficial effects of the present utility model clearer, the preferred embodiments of the present utility model will be described in detail below with reference to the accompanying drawings, so as to facilitate the understanding of the skilled person.

As shown in Figures 1-3, the new type of airport runway navigation aid light includes a lamp and a heat sink. The lamp includes a column 1, an LED lamp 2, a housing 3, a lamp holder 4, a light distribution mirror 5, and a fixing plate 6. The lower end of the column 1 is threaded and installed on the base 7, and the base 7 is fixed on the runway or the fixed platform by bolts. When the base 7 is fixed, a layer of shock-absorbing pad and sealing ring is placed between the base and the fixed surface, which will play a role in the navigation lights. A certain shock absorption effect, the upper end of the column 1 is threadedly connected with the lamp holder 4, and the column 1 is provided with a waterproof cover 8, and the outer wall of the column 1 is provided with threads.
