Abstract
A penetration and reflection type glare shield panel lampshade road luminaire consists of a light source, a reflector and a lampshade, and is characterized in that the lampshade is provided with a glare shield panel that has a certain reflection angle and a proper penetration and reflection ratio and reflection curved surface. The road luminaire of the utility model has the advantages of simple and novel structure, low cost, easy use, being capable of dealing with the contradictions of lighting, glare, energy saving and cost, thus leading the cost of road luninaire engineering to lower greatly. Therefore, the utility model has great economic and certain social benefits.
Description
One, technical field
The utility model relates to a kind of roads light, particularly a kind of Transflective antiglare shield lampshade roads light.
Two, background technology
At present, reducing on the road at night and eliminate the discomfort that dazzle causes driver and pedestrian, is one of problem of being concerned about most of street lamp designer thereby improve people to the observation ability of road object.People often take to improve pole height or light fixture are cut light handle for this reason, and two kinds of methods are used together sometimes, from the increase light source driver and pedestrian's horizontal irradiating angle are started with and reduce the influence of dazzle, improve people's observation and resolution capability.But these methods have been brought tangible negative consequences: because the increase of pole height, cost is increased rapidly, and light fixture cut light and handles and certainly will reduce energy use efficiency, in order to satisfy the requirement of illumination, the uniformity, also have to increase the density of lamp stand, this makes cost further strengthen again.
Three, summary of the invention
The purpose of this utility model is a kind of Transflective antiglare shield lampshade roads light of design, this light fixture is a kind of under the prerequisite that satisfies the road lighting requirement, the density that need not increase the height of lamp stand and strengthen lamp stand just can reduce the light fixture because of the optical energy loss of section light belt as far as possible, in order to overcome the deficiency that has light fixture now.
The purpose of this utility model can reach by following embodiment: this roads light is made up of light source, reflector and lampshade, light source, reflector are identical with existing light source and reflector, being characterized in being equipped with on lampshade one has certain reflection angle, and the antiglare shield of suitably saturating inverse ratio and curved surface is arranged; Antiglare shield can be located at the side and the bottom surface of lampshade, and antiglare shield also can be the part of lampshade, but it uses the other parts of material and lampshade different.
The utility model has the advantages that simple in structure, novel, cheap, easy to use, this roads light is based on the rational and effective reallocation to luminous energy, thereby solved the contradiction of illumination, dazzle, energy-conservation, cost preferably, can make the cost of road lighting engineering bigger reduction is arranged.Thereby tangible economic benefit and certain social benefit arranged.
Four, description of drawings
To be described in further detail the utility model in conjunction with the accompanying drawings down.
Fig. 1 is an overall structure schematic diagram of the present utility model
Fig. 2 is original roads light distribution curve flux figure
Fig. 3 is the utility model distribution curve flux figure
Five, the specific embodiment
As shown in Figure 1, this roads light is made up of light source 1, reflector 2 and lampshade 4, be characterized in that being equipped with one on the lampshade 4 of the side-lower of reflector 2 has certain reflection angle, the antiglare shield 3 that suitably saturating inverse ratio and curved surface are arranged, this anti-dazzle anti-plate 3 can be located at the side and the bottom surface of lampshade 4, this antiglare shield 3 can be the part of lampshade 4, but it uses the other parts of material and lampshade 4 different; This antiglare shield 3 has certain ability and the albedo of seeing through to light, thereby, through it, the light that light that the reflector right side reflects back and light source 1 direct projection are come, a part is left-hand transmissive At, Bt by former direction, a part then reflects to the right and removes Af, Bf, the light that these light and the reflection of lamp reflector left side come, and light source is superimposed at this regional direct projection light.So, the symmetrical expression distribution curve flux that just makes original light fixture becomes asymmetric formula distribution curve flux as shown in Figure 3 as shown in Figure 2.That is to say, originally light fixture can only distribute about luminous energy or front and back equivalent, this Transflective antiglare shield light fixture then can be assigned to the luminous energy major part right-hand or the place ahead, have only small part directive left or rear, so, driver from left to right and pedestrian when obtaining necessary illumination, the sense of discomfort that reduces to a great extent or avoided dazzle to cause.
The saturating anti-antiglare shield of this light fixture can be according to the specific requirement of different road lightings, sets placement location, saturating inverse ratio and curve form, with the best group that reaches illumination and anti-dazzle with.
Claims (3)
