Lamp

Abstract

The invention relates to a lamp. The lamp comprises a light source module, a lens module and a prism module, wherein the prism module corresponds to the light source module and converges lights of the light source module to the prism module; the prism module is used for refracting and outgoing the converged lights; the optical axis of the light source module and the lens module is vertical to an incident plane of the prism module; an emergent light of the prism module is vertical to an emergent plane, the lamp is a middle-line lamp of a runway; and when the deflection angle of the optical axis of the light source module and the lens module from the vertical incident plane is more than 0 degree and is less than or equal to 4 degrees and the deflection angle of the emergent light of the prism module relative to the vertical direction of the emergent plane is more than 0 and is less than or equal to 4.5 degrees, the lamp is a grounding strap lamp. The lamp not only can be used as a middle-line lamp of the runway, but also can be used as a grounding strap lamp, simultaneously meets the requirements of two kinds of lamps, is modular and multifunctional without need of designing the two kinds of lamps separately, and is convenient for design and production, thus greatly reducing the cost for design and production, saving the time and improving the efficiency.

Description

【Technical field】 [0001] The invention relates to a lighting tool, in particular to a lamp for airport runway navigation. 【Background technique】 [0002] The runway centerline lights and touchdown zone lights are both airport navigation lights, which are respectively set on the center line of the airport runway and both sides of the airport runway to guide the takeoff and landing of the aircraft. [0003] At present, most runway centerline lights and touchdown zone lights use tungsten-halogen lamps as light sources, with a lifespan of about 1,000 hours. The bulbs need to be replaced frequently, with low maintenance coefficient and high maintenance costs. In addition, tungsten-halogen lamps have high power and high energy consumption, which increases economic costs. It does not meet the requirements of current green energy utilization. At the same time, the traditional airport runway centerline lights and touchdown zone lights only have a single function. In the case of simi...

[0003] At present, most runway centerline lights and touchdown zone lights use tungsten-halogen lamps as light sources, with a lifespan of about 1,000 hours. The bulbs need to be replaced frequently, with low maintenance coefficient and high maintenance costs. In addition, tungsten-halogen lamps have high power and high energy consumption, which increases economic costs. Does not meet the current requirements of green energy utilization

At the same time, the traditional airport runway centerline lights and touchdown zone lights only have a single function. In the case of similar light intensity requirements, they are designed and managed separately as two different projects. Different refraction systems are used, and the prism modules are different. , so that the development process is extended, and the experiment and verification are carried out separately, which is time-consuming and labor-intensive, and increases the R&D cost; different prism modules require the development of two different molds, which increases the production cost
