Description

TECHNICAL FIELD

[0001] The present application relates to a lighting lamp, in particular to a light reflection lighting lamp with light guide rail. BACKGROUND

[0002] With the development of national transportation network, guardrail lamps are gradually popularized and become important road lighting lamps that can replace vertical pole street lamps. Guardrail lamps have the advantages of low glare, high light utilization rate, easy installation and maintenance, etc., and meet the comfort and energy saving and environmental protection requirements of road lighting. Conventional guardrail lamps mainly use lenses for light distribution design. By designing special polarizing structure of the lens, the light of the LED light source is deflected and converged to the far distance of road lighting, and a clear cut-off line is formed. However, the lens structure inevitably has a small part of stray light overflowing to the position above the cut-off line, causing glare that stimulates the eyes during driving. A new type of guardrail lamp uses a reflector structure for light distribution design, which has the advantage of completely cutting off the light above the cut-off line, realizing glare-free lighting in the vertical direction of the lamp. However, both the existing lens light distribution guardrail lamp and the reflector light distribution guardrail lamp have light in the opposite direction of the lane. If the construction team does not properly install the angle of the lamp during installation, the lamp will have a large upward angle, causing serious glare and affecting the safe driving of the driver.

[0004] The highway guardrail plate of the above patent document has a lighting function, but in actual application, there is serious glare, which affects the safe driving of the driver. SUMMARY

[0006] To achieve the above purpose, the technical solution adopted by the present application is:

[0007] The application discloses a light-reflecting lighting lamp for a light-reflecting guardrail, which comprises a long strip-shaped light-reflecting cover and a plurality of lighting lamps.

[0008] Further, the light-reflecting plate is obliquely arranged on the long strip-shaped light-reflecting cover, so that a part of the reflected light is directed to the road.

[0012] Further, in the horizontal direction, if the direction of the inner side edge of the light-reflecting plate closer to the lighting lamp is 0° azimuth angle, then the azimuth angle of the outer side edge of the light-reflecting plate closer to the lighting lamp is 147°, the azimuth angle of the outer side edge of the light-reflecting plate farther to the lighting lamp is 266°, and the azimuth angle of the inner side edge of the light-reflecting plate farther to the lighting lamp is 273°; the light emitted by the lighting lamp in the range of 147°-266° is free, the light emitted by the lighting lamp in the range of 266°-273° is absorbed by the black light-absorbing surface, and the light emitted by the lighting lamp in the range of 273°-360° is reflected to the road surface through the long strip-shaped light-reflecting cover.

[0030] Embodiment 1 ​​​​​

[0031] As Figure 1 , 2 , 3, 4, 5 shows a light reflecting light along the guardrail lighting lamps, including a long strip-shaped light reflector 1 and a plurality of lighting lamps 2, long strip-shaped light reflector 1 is set in the guardrail and along the road direction arrangement, a plurality of lighting lamps 2 is distributed in the long strip-shaped light reflector 1, the long strip-shaped light reflector 1 is distributed with a plurality of light-reflecting plate 3, a lighting lamp 2 corresponds to a light-reflecting plate 3, the light-reflecting plate 3 on the side of the lighting lamp is close to the reflecting surface 4, the color is milky white, the other side of the light-reflecting plate 3 away from the lighting lamp is black light-absorbing surface 5. The long strip-shaped light reflector 1 includes the top surface of the light-reflecting plate 6 and the arc-shaped light-reflecting side plate 7, the side of the top surface of the light-reflecting plate 6 is connected with the upper side of the arc-shaped light-reflecting side plate 7, the lighting lamp 2 is arranged on the lower surface of the top surface of the light-reflecting plate 6. The long strip-shaped light reflector 1 and the light-reflecting plate 3 are made of aluminum material. The long strip-shaped light reflector and the light-reflecting plate are integrally formed.

[0032] The lighting lamp is a Led lamp, which can be a lamp bead or a group of lamp beads composed of two or more lamp beads, configured according to actual needs.

[0033] The light-reflecting plate 3 is inclinedly installed on the long strip-shaped light reflector 1, so as to make the reflected part of light rays shoot toward the road direction.

Specifically, the plate surface of the light-reflecting plate is a curved surface, wherein the reflecting surface is an inner concave surface, and the black light-absorbing surface is an outer convex surface. Since the light-reflecting plate is additionally arranged on the original long strip-shaped light reflector, and the front and back surfaces of the light-reflecting plate adopt the structure forms of light reflection and light absorption, the light-reflecting plate intercepts and reflects the light rays in the opposite direction of the LED lighting lamp, thereby enhancing the lighting intensity of the light along the road and improving the comfort of the road lighting. Of course, the light-reflecting plate 3 shields the light rays of the lighting lamp, and the black light-absorbing surface of the light-reflecting plate is an outer convex surface, which realizes no glare in the direction along the road,

[0036] Embodiment 2

[0037] It is worth emphasizing that the reflector plate 3 is designed in a curved structure, which is the best technical solution. In addition to the curved structure, the reflector plate 3 can also be designed in a flat structure.
