Embodiment Construction

[0042] figure 2 It is a schematic diagram of a lighting device in a preferred embodiment of the present invention. Please refer to figure 2 , the lighting device 200 is used to illuminate a first region R and a second region F, the first region R is, for example, a road, and the second region F is, for example, a road shoulder. The lighting device 200 includes: a first light source module 210 and a second light source module 220 . The first light source module 210 provides a first light L1 with a first spectral composition. The first light L1 has a visual ratio (S / P ratio) less than 2, and the visual ratio is defined as a ratio of scotopic luminosity (S) to photopic luminosity (P). The second light source module 220 provides the second light L2 with the second spectral composition. The second light L2 has a visual ratio greater than 2, wherein the color temperature of the second light L2 is similar to that of the first light L1 , and the scotopic efficacy of the second l...

Abstract

The invention discloses a lighting device used for lighting up adjacent a first area and a second area. The lighting device comprises a first light source module and a second light source module. The first light source module is provided with a first light ray formed by a first spectrum. The first light ray has a visual ratio (S/P) smaller than 2, and a definition of the visual ration is a ratio of a noctovision luminosity (S) and a daylight vision luminosity (P). the second light source module is provided with a second light ray formed by a second spectrum. The second light ray has a visual ratio bigger than 2, wherein color temperature of the second light ray is similar to that of the first light ray, and noctovision efficiency of the second light ray is bigger than that of the first light ray. The noctovision efficiency is defined as a ratio of the noctovision luminosity and power. The lighting device can consider both lighting security demand and energy saving demand.

Description

technical field [0001] The present invention relates to a lighting device, and in particular to a lighting device for roads and road shoulders, which can meet both lighting safety requirements and energy saving requirements. Background technique [0002] In the outdoor low-light environment (Dim ambience) at night, there is a contradiction between lighting safety requirements and energy-saving requirements of lighting devices (such as street lamps, etc.). Furthermore, a safe driving environment can be provided by adequately illuminating the road, but the time for people and vehicles to pass by is not much, which causes a waste of lighting energy. On the other hand, the waste of lighting energy can be reduced by shortening the lighting time of street lights and reducing the number of street lights. However, insufficient lighting will cause traffic and security concerns. [0003] figure 1 It is a schematic diagram of the lighting device for lighting the road and the shoulder...
