Field emission lamp

Abstract

The invention discloses a field emission lamp which comprises a base plate, a plurality of connecting pieces and light source assemblies arranged on the base plate. The base plate comprises a plurality of tube bodies which are sequentially arranged in a sleeved mode, and the tube bodies are made of transparent materials. One end of each tube body comprises a sleeve tube end, and each sleeve tube end is arranged at the other end of another tube body in a sleeved mode. The connecting pieces are arranged at the sleeve tube ends. When the field emission lamp is telescoped or unfolded, the tube bodies can not be disengaged from one another, and therefore the field emission lamp with large light-emitting area is obtained by a simple manufacturing technology. The first wall faces of the tube bodies are the outer surfaces of the tube bodies, and the second wall faces of the tube bodies are inner cavities of the tube bodies. The transparent light source assemblies are placed between the first wall faces and the second wall faces, the transparent base plate and the transparent light source assemblies are used so that the field emission lamp can achieve overlaid light emitting in the telescoping process, the field emission lamp can be folded along the center axis of the field emission lamp in a rotating mode when being not used, and carrying is convenient.

Description

technical field [0001] The invention relates to the field of lighting, in particular to a field emission lamp. Background technique [0002] The existing field emission light source is a new type of light source, which has the advantages of energy saving, environmental protection and power saving, and is gradually being widely used in light source systems for decoration, lighting or indication. [0003] In the prior art, in order to achieve a certain brightness, the field emission lamps need to have a certain light-emitting area, and the larger the light-emitting area, the higher the requirements for the preparation technology, and most of the field emission lamps are fixed structures, and the field emission lamps are large-scale lamps Structure, carrying and transportation are less convenient. Contents of the invention [0004] The purpose of the present invention is to provide a field emission lamp that is easy to prepare, convenient to carry and transport, and capable ...
