Below to be applied to the light-distribution lens assembly of Tunnel Lamp, describe the detailed description of the invention of the light-distribution lens assembly that the utility model embodiment provides in detail.
Tunnel Lamp is used for tunnel illumination, and due to the geographical environment that tunnel is special, Tunnel Lamp provides the brightness of illumination, illumination and luminance uniformity, uniformity of illuminance etc. must meet the lighting requirement in tunnel, to ensure the traffic safety in tunnel.For the light-configuration mode of conventional tunnel lamp, be the bulk according to tunnel and light fixture arrangement design light-distribution lens, adopt single lens to be Tunnel Lamp luminous intensity distribution.But when the bulk in tunnel is different, just need to redesign lens, this needs a large amount of human cost of cost and die cost, greatly can increase the cost of engineering project.
The present embodiment provides a kind of light-distribution lens assembly being applied to Tunnel Lamp, adopts existing two kinds of lens with different distribution curve flux on market to carry out combining the luminous intensity distribution realizing Tunnel Lamp, can ensure the lighting requirement met in tunnel after cloth lamp.
See Fig. 1, described light-distribution lens assembly comprises multiple lens, and multiple described lens distribute with the electroluminescent lamp pearl one_to_one corresponding in light fixture respectively, and pearl is arranged on printed substrate electroluminescent lamp.
Described multiple lens comprise first lens with the first distribution curve flux and second lens with the second distribution curve flux, and described first lens and the second lens can adopt existing lens on market.
Wherein, the distribution curve flux of the first lens and the second lens possesses following condition respectively:
The distribution curve flux of the first lens, i.e. described first distribution curve flux, in 0-180 ° of plane, its largest light intensity position overlaps with center, and namely on 0-180 ° of direction, largest light intensity is 0 ° of position, and distribution curve flux general performance is mellow and full full.See Fig. 2, Figure 2 shows that the distribution curve flux of the first lens provided in the present embodiment.Particularly, the ratio of its largest light intensity and central light strength is close to 1:1, and the center of curve is outstanding larger.
The distribution curve flux of the second lens, i.e. described second distribution curve flux, in 0-180 ° of plane, its largest light intensity position is positioned at the position, 60 ± 5 degree, both sides of center.The ratio of largest light intensity and central light strength is between 2 ~ 3.5.As shown in Figure 3, Fig. 3 is the distribution curve flux of the second lens in the present embodiment.Can see by figure, on 0-180 ° of direction, central light strength is very little, largest light intensity in the both sides (near 60 ° of positions) of center, largest light intensity/central light strength ≈ 3:1.From distribution curve flux figure, center of curve depression is comparatively large, and light beam comparatively " thin ".
Below for the illumination of certain tunnel interlude, adopt Dialux software to do illumination simulation, come to adopt more separately the first lens, the second lens and by illuminating effect during two kinds of lens matched combined.Wherein, Tunnel Lamp is specifically arranged as: lamp installation height 5.1 meters, spacing 12 meters, Bilateral Symmetry cloth lamp, width of roadway 10.8 meters, installs 10 °, the elevation angle, maintenance factor 0.7.
When adopting the first lens to be Tunnel Lamp luminous intensity distribution separately, adopting Dialux software to carry out illumination simulation, obtaining result as shown in table 1:
The illumination analog result of table 1 first lens
When adopting the second lens to be Tunnel Lamp luminous intensity distribution separately, adopting Dialux software to carry out illumination simulation, obtaining result as shown in table 2:
The illumination analog result of table 2 second lens
Can be found out by above-mentioned illumination analog result, when adopting separately the first lens light, longitudinal luminance uniformity numerical value is higher, and that is longitudinal luminance uniformity is high, but brightness value is on the low side.Improve brightness if therefore want in actual applications, need to improve lamp power, can power consumption be increased like this, be unfavorable for energy-conserving and environment-protective.
When adopting separately the second lens light, brightness value and brightness value are all higher, but longitudinal luminance uniformity is on the low side.When practical application, road surface there will be speck and blackening (i.e. zebra effect), the easy like this Driver Vision that causes is tired, causes a hidden trouble to traffic safety.
See table 3, table 3 is depicted as two kinds of lens matched combined luminous intensity distributions, and wherein the number ratio of the first lens and the second lens is 2:3.Certainly, when the bulk in tunnel changes, the first lens can correspondingly regulate to the number ratio of the second lens, to meet lighting requirement.First lens and the distribution on a printed-wiring board of the second lens are arbitrary.
The illumination analog result of table 3 lens subassembly
Can see from table 3, when first lens and the second lens matched combined are carried out luminous intensity distribution, under the prerequisite not improving whole lamp power, the advantage of two kinds of lens can be taken into account, in the analog result obtained, brightness value increases, longitudinal luminance uniformity also reaches more than 0.7 simultaneously, thus can meet the lighting requirement in tunnel.
Therefore, the light-distribution lens assembly that the present embodiment provides, adopt the lens matched combined of two kinds of different distribution curve fluxs conventional on market, by regulating the number ratio of two kinds of lens in lens subassembly, Tunnel Lamp can be made to meet the lighting requirement in tunnel, not only the brightness of illuminating lamp reaches requirement, and can provide uniform illumination.Thus, avoid redesign lens, not only can save design cost and die cost, greatly reduce costs; And avoiding design cycle and Mould Machining cycle, product hands over the phase faster, is conducive to accelerating engineering project progress.
The utility model embodiment also provides a kind of LED tunnel lamp, is provided with light-distribution lens assembly as above.
Above the light-distribution lens assembly of LED illumination lamp provided by the utility model and LED tunnel lamp are described in detail.Apply specific case herein to set forth principle of the present utility model and embodiment, the explanation of above embodiment just understands method of the present utility model and core concept thereof for helping.Should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model principle, can also carry out some improvement and modification to the utility model, these improve and modify and also fall in the protection domain of the utility model claim.
