Description

LED Tunnel Lamp device

Technical field the utility model relates to the lighting fixture that is used for street or outdoor lightings such as road, tunnel, especially relates to the LED Tunnel Lamp that uses light emitting semiconductor device, particularly relates to LED Tunnel Lamp device.

The background technology Tunnel Lamp is the pith of tunnel illumination, traditional Tunnel Lamp often adopts high-pressure mercury lamp, its light efficiency is higher, but this class light source is in application the time, have only 40% only shine directly into the road surface, the lighting angle of fluorescent tube is 360 °, most of light must be by just shining the appointed area after the reflector reflection, routine tunnel illumination system is for passing through to set relevant corresponding parameter with luminous flux outside the hole in the hole, the multistage illumination regulation device that setting can be controlled is along separate routes turned off the light along separate routes and is turned on light by multistage light modulating device adjustment.The efficient of general Tunnel Lamp reflector only is 50% to 60%, and whole Luminaire efficiency generally only has 70%, and the reflector design difficulty is big, can't really satisfy light distribution requirements.Owing to relating to tunnel illumination operation and construction cost reason, according to design specification, each road tunnel illuminating lamp distributes by certain design spacing distance and is provided with, and makes behind the dim light inevitable in the irregular hot spot phenomenon of ground formation illumination.

In recent years, along with the reinforcement of people's environmental consciousness, various environmental protection, energy-saving illumination product continue to bring out out like the mushrooms after rain, and the especially development of LED lighting engineering is for functional illumination provides possibility.Prior art LED lighting engineering is not only in the decorative lighting field, and also occupy a tiny space at functional lighting field, LED is as a kind of solid light source, with its long-life, high light efficiency, how photochromic and once light-distribution directional illumination function, can under the safety low-voltage, work, also the switch sudden strain of a muscle is disconnected continuously, can easily realize many advantages such as 0～100% dimming function, becomes the development trend of light source of new generation.In the road lighting field, the LED Tunnel Lamp is constantly developing to replace the conventional high-tension sodium vapor lamp.
