Abstract

The invention discloses a lamp which is mounted on a road, the road comprises lanes opposite in advancing direction, and the lanes are separated by a central line. The lamp is arranged at an elevated position of the central line, and light emitted by a lighting component in the lamp and used for lighting the preset lane of the road is evidently controlled in the advancing direction of the preset lane. An optical component is arranged on the outer side of the lighting component of the lamp and used for reflecting the light to the preset lane to form a first emergence area and a second emergence area. The lamp mounted at the central line deflects toward one of the lanes by a deflection distance and the lighting component inclines towards the other lane by a correction angle to enable the first and second emergence areas to be different in light shape. Therefore, the lamp can be applied to lighting demands of different light shapes and especially applied to lighting in tunnels.

Description

Light fixture

Technical field

The present invention about a kind of light fixture, espespecially a kind of light fixture of the shape lighting demand that can be applicable to not share the same light.

Background technology

Light emitting diode (Light-Emitting Diode, LED) is a kind of semi-conductor electricity sub-component that can be luminous, and it utilizes electric energy to change into the mode luminescence of luminous energy.Utilize light emitting diode to carry out alight to have that luminous efficiency is high, the life-span be long, not cracky and the advantage such as reaction speed is fast, so replace traditional lamp gradually.

The illumination light shape that the street lamp of current use LED light source produces, normally in oblong or the light shape close to long rectangle, these two kinds of light shapes distributions are the light shape of X-direction or Y-direction symmetry.As TaiWan, China patent announcement No. I312398 " street lamp of tool ellipse LED " patent, namely disclose the LED lens that light emitting diode is arranged in pairs or groups, the light shape ratio that the major axis of its transmissive portions and minor axis scatter is between 1.5 to 5.By the extension of transmissive portions in long axis direction, irradiation light shape is made to be long ellipticity and the light source module range of exposures that can increase, to promote the light efficiency rate of street lamp.

So, if use the street lamp of above-mentioned LED light source, when being installed in tunnel, because of installation position skew road center, again because this LED light source street lamp has the light shape of X-direction or Y-direction symmetry, make the light exposed on track, road both sides cannot be even.

Summary of the invention

Namely technical problem solved by the invention is providing a kind of light fixture, espespecially a kind of light fixture of the shape lighting demand that can be applicable to not share the same light.

The technology used in the present invention means are as described below.A kind of light fixture, this light fixture is installed on a road, and this road comprises the contrary track of direct of travel, separate by the Central Line.This light fixture is arranged at a frame high position at place of Central Line, and be configured to the light fixture in light fixture is exported led control significantly to the direct of travel in these tracks in order to the light illuminating predetermined track in road; Optical module is provided with outside the light fixture of this light fixture, in order to light reflection has been exported the first exit area and the second exit area respectively to these tracks, this light fixture is installed in this Central Line towards a wherein lane shift one offset distance S, an angle correction θ and this light fixture system tilts towards another track, it is as follows that it meets relational expression:

θ = {Sin}^{- 1} \frac{S}{\sqrt{} (S^{2} + H^{2})}

Wherein, H is arranged at the setting height(from bottom) on this road, the shape and this first exit area and the second exit area tool are not shared the same light for this light fixture.

By this, allow this first, second exit area tool not share the same light shape, namely the present invention like this can be applicable to the lighting demand of different light shape, is especially applied to the illumination in tunnel, uniform light can be allowed to expose on the track of road both sides, guarantee traffic safety.

For reaching above-mentioned purpose, described optical module is reflecting plate.

For reaching above-mentioned purpose, described light fixture is plural light emitting diode.

For reaching above-mentioned purpose, described first exit area and the different geometric figure of the second exit area tool.

For reaching above-mentioned purpose, this light shape of described first exit area is less than this light shape of this second exit area.

The beneficial effect that the present invention produces is as follows: meet shape lighting demand of not sharing the same light, uniform light can be allowed to expose on the track of road both sides, guarantee traffic safety.

Detailed description of the invention

If Fig. 1 is the structural representation that light fixture of the present invention is installed in road, and Fig. 2 is installed in shown in another viewing angle constructions schematic diagram of road for light fixture of the present invention, light fixture 1 of the present invention is installed on a road 2, this road 2 comprises first, second contrary track 21,22 of direct of travel, separate by the Central Line 23.This light fixture 1 is arranged at a frame high position at place of Central Line 23, shown in Fig. 3, the optical module 12 that this light fixture 1 is provided with a light fixture 11 and is positioned at outside it, and be configured to the light fixture 11 in light fixture is exported led control significantly to the direct of travel in this first, second track 21,22 in order to the light illuminating predetermined track in road.

Wherein, the optical module 12 of this light fixture can by light fixture 11 by light reflection to this first, second track 21,22, and exported the first exit area 31 and the second exit area 32 respectively, that is this light fixture 11 has the first exit area 31 towards the output of this first lane 21, and have the second exit area 32 towards the output of this second lane 22, in this case embodiment, this optical module 12 is reflecting plate, and this light fixture 11 is plural light emitting diode.

This light fixture 1 is installed in this Central Line 23 and offsets an offset distance S towards wherein first lane 21, and this light fixture 11 to tilt an angle correction θ towards another second lane 22, and its satisfied pass formula is as follows:

θ = {Sin}^{- 1} \frac{S}{\sqrt{} (S^{2} + H^{2})}

Wherein, H is the setting height(from bottom) that this light fixture 1 is arranged on this road 2, the shape and this first exit area 31 and the second exit area 32 tool are not shared the same light, shown in Fig. 3, make this light fixture 11 emergent light tool asymmetrical beam shape, and the emergent light of light fixture 11 can comprise the emergent light of shape of not sharing the same light, thus provide illumination to penetrate distant emergent light and tool different light penetrates the larger emergent light of area, with the lighting environment in response to different user demand simultaneously.Especially be applied to the illumination in tunnel, uniform light can be allowed to expose on the track of road both sides, guarantee traffic safety.

Moreover as shown in Figure 4, this first exit area 31 and the different geometric figure of the second exit area 32 tool, this light shape of this first exit area 31 is less than this light shape of this second exit area 31.

It is worth mentioning that, the present invention utilizes light fixture to be obliquely installed on this road, and its optical module of arranging in pairs or groups, the luminous intensity distribution of controllable in direction of having a lot of social connections is asymmetrical beam shape, can be applicable to the illumination in tunnel, uniform light can be allowed to expose on the track of road both sides, guarantee traffic safety.
