Description

Flat plate type LED tunnel lamp

Technical Field

Background

At present, among light sources adopted in tunnel lighting applications, a high-pressure sodium lamp is applied in a large scale due to high photopic luminous efficiency (up to 120lm/W), but the high-pressure sodium lamp still has some problems difficult to overcome in tunnel lighting, mainly including poor color rendering and limited light source power selection range (usually, only 250W and 400W can be selected), and particularly in internal section lighting, the high-pressure sodium lamp does not have small power on one hand, and on the other hand, glare and frequency flash caused by a point strong light source are serious.

In some long tunnels, straight tube fluorescent lamps are also used due to their high color rendering and good visual inductivity of linear lighting, but because the fluorescent lamps have short life, usually only about 8,000 hours, they need to be replaced frequently, which greatly increases the maintenance cost of tunnels. In addition, the power of the fluorescent lamp is small, and the area requiring high illumination, such as the inlet section, the transition section, and the outlet section, cannot meet the requirement. With the maturity of electrodeless lamp technology in recent years, the electrodeless fluorescent lamp has longer service life and higher power compared with the traditional fluorescent lamp due to elimination of influence of electrode factors, so that the electrodeless lamp has advantages in tunnel illumination occasions. However, the electrodeless lamp has a large light emitting surface, and the optical efficiency of the whole lamp is low when the optical design is performed.

Therefore, there is a need to develop a flat-type LED tunnel lamp that integrates the advantages of a high-pressure sodium lamp, a straight-tube fluorescent lamp and an electrodeless lamp, so as to meet the requirements of high luminous efficiency, long service life, uniform light emission and glare prevention of modern tunnel lamps.
