Embodiment Construction

[0037] In order to make the objectives, technical solutions and advantages of the present invention clearer, the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that, the embodiments in the present application and the features in the embodiments may be arbitrarily combined with each other if there is no conflict.

[0038] The above background technology has already explained that LED light sources have been commonly used in existing aviation light sources. However, LED chips have higher requirements on heat dissipation performance during operation, and the increase in temperature will lead to damage to their luminous efficiency, thereby reducing the product's performance. service life. Therefore, it is particularly necessary to solve the problem of heat dissipation of the light source.

[0039] For a specific type of LED chip, its own heat dissipation performance has been determined, and th...

Abstract

The embodiment of the invention discloses a light source structure of an aviation landing lamp. The light source structure comprises a light source shell, a light source assembly, a cover plate assembly, a radiator assembly and a driver assembly. In the light source shell, a shell substrate and shell side plates form an open type light source cavity used for installing a light source assembly, and the light source assembly is sealed through a cover plate assembly. The radiator assembly comprises at least two rows of radiating fins which are vertically arranged, and a middle partition area is arranged between every two adjacent rows of radiating fins. The driver assembly comprises a driver body and a driver supporting column, and the driver supporting column is fixedly connected to the driver screw installation hole of the shell substrate through a fixing screw so that the driver assembly can be fixedly installed on the side, provided with the radiator assembly, of the light source shell. According to the embodiment of the invention, the problem that the service life of a landing lamp product is shortened due to the fact that the lighting effect of an existing aviation LED light source is damaged due to temperature rise is solved.

Description

technical field [0001] The invention relates to, but is not limited to, the technical field of off-board lighting equipment, in particular to a light source structure for an aviation landing light. Background technique [0002] With the development of airborne lighting technology, China has put forward higher requirements for the comprehensive performance of lighting equipment, including light performance, control performance and its shape characteristics. [0003] High-power lighting equipment in the aviation field mainly includes landing lights, taxi lights, navigation lights, marker lights and refueling lights. According to statistics, LED light sources have been widely used in various products at home and abroad. As a new generation of light sources, LED light sources have obvious advantages in light weight, long life and high light efficiency compared with traditional light sources. However, LED chips have higher requirements on heat dissipation performance during oper...
