Embedded illumination device

Abstract

The invention is applicable in the field of illumination devices and discloses an embedded illumination device, which comprises a light emitting member and a shell component, wherein the shell component comprises an upper shell and a lower shell, which are fixedly connected and form an inner cavity in between; the light emitting member is fixedly arranged in the inner cavity; the upper shell is provided with a light outlet window; the lower shell is provided with positioning convex blocks; and at least two positioning grooves matched with the positioning convex blocks are formed on the upper shell along a circumferential direction. In the embedded illumination device provided by the invention, the positioning convex blocks are arranged on the lower shell and the two positioning grooves matched with the positioning convex blocks are formed on the upper shell, so that the positioning convex blocks and the positioning grooves form an assembly positioning structure; by inserting the positioning convex blocks into different positioning grooves, different requirements of the illumination devices on two sides of the central line of an athletic track can be met without designing upper shells of two specifications nor regulating the position of the light emitting member; and the product is produced at low cost and convenient to assemble and the generality of the product is high.

Description

technical field [0001] The invention belongs to the field of lighting devices, in particular to an embedded lighting device for airport runways. Background technique [0002] Embedded touchdown zone lights distributed on both sides of the runway center line need to be installed on the airport runway. According to the relevant standards, the light beam of the touchdown belt light needs to incline 4 degrees to the center line of the runway. In the prior art, there are two types of embedded grounding zone lights: a left grounding zone light and a right grounding zone light, and the two embedded grounding zone lights are designed and manufactured separately. At present, there are two types of grounding zone lights, the side grounding zone light and the right grounding zone light. Some need to make two kinds of housings to make the light beam incline 4 degrees to the center line of the runway, resulting in high design and manufacturing costs and poor product versatility; Althou...

Problems solved by technology

At present, there are two types of grounding belt lights, the side grounding belt light and the right grounding belt light. Some need to make two kinds of housings to make the light beam incline 4 degrees to the center line of the runway, resulting in high design and manufacturing costs and poor product versatility; Although the same shell is used, it is necessary to adjust the installation position and angle of the halogen tungsten light source inside the lamp to make the light beam incline 4 degrees to the center line of the runway, which is inconvenient to assemble and poor in product versatility
