Problems solved by technology
In the former expressway without street lights, it is generally necessary to turn on the high beam headlights of the vehicle when driving, so that the driver can see clearly the road ahead of the vehicle and the road a little farther away. Strong reflections are formed in the rearview mirror and reversing mirror of the car, which affects the sight of the driver in front and poses a safety hazard
The latter type of high-altitude LED street lamp speedway, because the LED street lamp light module is set at high altitude, on the one hand, it is inconvenient to maintain at high altitude, on the other hand, the light output module is very high from the ground, the irradiation distance is long, and the light loss is also large, which wastes electric energy.

Embodiment Construction
[0020] The present invention will be described in further detail below in conjunction with the accompanying drawings. refer to figure 1 , figure 2 , the first embodiment of the present invention is a combination of LED street lamps, which is suitable for highways; its feature is that: the height of the light emitting surface of the LED street lamp is between 600mm and 1500mm; the light emitting surface of the LED street lamp is downward and forward tilt. There is a separation strip between the two-way lanes of the expressway. The setting of the isolation strip reduces the influence of street lights on vehicles in the other lane. The expressway has two lanes in one direction. On the dual lane, when the vehicles are dense, the vehicle's own lighting can be completely independent. At this time, the vehicle's own lighting is auxiliary lighting and warning lights. Along the direction of the one-way lane of the expressway, the LED street lights on the left and right sides are ...

Abstract
The invention relates to a roadway lighting technology for expressways and provides an LED (Light Emitting Diode) street lamp combination applicable to expressways. The LED street lamp combination is characterized in that a light exit face of an LED street lamp is 600mm-15000 mm high and is inclined downwards and forwards. The invention provides the LED street lamp combination which is applicable to expressways and has the advantages of high safety, convenient maintenance and energy saving.
Description
technical field [0001] The invention relates to highway lighting technology. Background technique [0002] LED lights have the characteristics of long life and power saving, and are more and more widely used in the field of lighting, especially street lighting. [0003] Existing highway street lights generally use high-pressure sodium lamps. Ordinary LED street lights are not widely used due to the bottlenecks in light efficiency, heat dissipation, and color rendering. [0004] Existing expressway has two kinds roughly, and a kind of is not to establish street lamp, and road marking and warning sign all adopt reflective material, generally need to open high beam when vehicle runs at a high speed. The other is to use the same or similar combination with high-pressure sodium lamps, that is, to set LED street lights (traditionally high-pressure sodium lamps) at high altitudes. In the former expressway without street lights, it is generally necessary to turn on the high beam h...
