Embodiment 1

[0041] This embodiment provides a low-level lamp, which is suitable for installation on both sides of the road and used for night lighting. The color temperature of the low-level lamp is 3000K, the color rendering index is 70, and the brightness is 0.5cd / m 2 ; When the low-position lights are installed on both sides of the road, the vertical height of the low-position lights from the ground is 1m.

[0042] The inventor of the low-level light in this embodiment, on the basis of the existing technology, conducted continuous research on the luminous quality of the low-level light. On the premise of considering the driver's night-time dynamic driving visual recognition requirements and the non-visual photobiological effect of the human body, the inventor selected Determined the three indicators of color temperature, color rendering index and brightness level that have a significant impact on luminous quality, and conducted a lot of research on their values; after research, the inve...

Embodiment 2

[0098] This embodiment provides an application of a low-position lamp in road lighting, and the low-position lamp is the low-position lamp described in Embodiment 1.

[0099] In this embodiment, the installation interval between two adjacent low-position lamps is 4-12 meters. As a preferred solution, the installation interval of two adjacent low-position lamps is 5-10 meters.

[0100] Such as Figure 4-5 As shown, by controlling the light-emitting angle of the low-level lights, the light can be effectively projected to the center area of ​​the roadway, meeting the road brightness requirements, avoiding projecting light into the sky or other places other than the road surface, and effectively ensuring the brightness and brightness of the road surface Evenness.

Abstract

The invention provides a low-position lamp and application thereof in roadway illumination. The low-position lamp is suitable for being installed on the two sides of a roadway and is used for night illumination, the color temperature of the low-position lamp ranges from 3,000 K to 4,000 K, the color rendering index of the low-position lamp is larger than or equal to 70, and the luminance of the low-position lamp is larger than or equal to 0.5 cd/m<2>; when the low-position lamp is installed on the two sides of the roadway, the vertical height of the low-position lamp from the ground ranges from 0.6 m to 1.2 m. When the low-position lamp is installed on guard bars arranged on the two sides of the roadway, illumination is uniform, no glaring or flickering is generated, the illumination light effect is high, the life is long, a driver achieves the high driving comfort under irradiation of the light source, visual cognition is quick and accurate, and the safety is high.

Description

technical field [0001] The invention relates to the technical field of road lighting, in particular to a low-position lamp and its application in road lighting. Background technique [0002] In the prior art, high-pole lamps are mostly used for illumination of viaducts, bridges connecting bridges and tunnels, large-scale interchange hubs, tunnel entrances and exits, self-rescue ramps, urban roads, etc. Or a single high-power lighting source. This lighting method has the following technical defects; 1) high cost; according to the investment estimate of the traffic engineering project issued by the Ministry of Communications, the cost of a 30m high pole lamp in the highway interchange area is about 15,000 yuan. The cost of lighting is not only high at one time, but also the cost of maintenance in the later period is high; 2) light pollution is serious; after high-pole lights are used for lighting the connecting roads, bridges, and tunnel entrances and exits of the tunnel grou...
