Abstract
The utility model discloses a batwing light distribution LED (light-emitting diode) tunnel lamp lens which is characterized in that the batwing light distribution LED tunnel lamp lens is a concave-convex lens, and comprises a light distribution structure (1); and an LED light source clamping groove structure (2) is arranged at the bottom of the light distribution structure (1), a step structure (3) and a reinforcement structure (4) are arranged on an outer ring of the light distribution structure (1), a positioning and fixing hole structure (5) is arranged on the reinforcement structure (4), and a sealing groove structure (6) is arranged at the bottom of the reinforcement structure (4). The batwing light distribution LED tunnel lamp lens can enhance the light efficiency, is reasonable in light distribution, high in brightness uniformity, small in dazzling light and suitable for lighting of road tunnels and can further meet driving conditions and ensure the driving safety; furthermore, the batwing light distribution LED tunnel lamp lens is simple in mounting and good in protection performance.
Description
Technical field
The utility model relates to a kind of lens, particularly a kind of batswing tab light-distribution LED Tunnel Lamp lens.
Background technology
Vcehicular tunnel is the narrow and small tubular structure thing in space, in order to reach the road speed of regulation, guarantee traffic safety, its operation lighting requirement is higher than general open-air road lighting, and its main feature is that the brightness of requirement road surface is big, uniformity height, dazzle is little, and require anti-greasy dirt ability strong, easy cleaning, the life-span is long etc.High power LED tunnel lamp is compared with the high-pressure mercury lamp of routine, and advantage such as have efficient, safety, energy-saving and environmental protection, the life-span is long, response speed is fast, colour rendering index is high, and stepless brilliance is adjustable can be widely used in highway tunnel illumination.Simultaneously, the development of LED lighting engineering is rapid, and the high-power LED light source light efficiency has reached about 120lm/W, and the whole light of LED Tunnel Lamp is imitated and also reached 100lm/W, becomes possibility thereby make the LED Tunnel Lamp be widely used in highway tunnel illumination.And under the social overall background of environmental protection, energy-saving and emission-reduction, LED Tunnel Lamp overall application must be the direction of future development in highway tunnel illumination.The development of LED Tunnel Lamp must need perfect lens to match with it.Existing LED Tunnel Lamp lens are not very desirable, and its light transmittance is low, cause the light fixture light efficiency to descend, and luminous intensity distribution is unreasonable simultaneously, causes the tunnel road surface luminance uniformity low, is easy to generate the zebra stripes phenomenon, influences traffic safety.
At present, the lens that the LED Tunnel Lamp on the market is furnished with, its size differs, and some can not reach concrete light distribution requirements, some very big waste that causes material again.In addition, also there are complicated, the problems such as water proof and dust proof is not in place, later maintenance difficulty of installing.
The utility model content
The purpose of this utility model is, a kind of batswing tab light-distribution LED Tunnel Lamp lens are provided, and it can make light efficiency rise, and luminous intensity distribution is reasonable, the luminance uniformity height, dazzle is little, is suitable for highway tunnel illumination and uses, satisfy driving condition and guarantee traffic safety, and install simply, protective is good.
The technical solution of the utility model: a kind of batswing tab light-distribution LED Tunnel Lamp lens, it is characterized in that: be a concave-convex lens, comprise light distribution structure, the light distribution structure bottom is provided with led light source draw-in groove structure, the light distribution structure outer ring is provided with ledge structure and ruggedized construction, ruggedized construction is provided with location and fixation hole configurations, and the ruggedized construction bottom is provided with seal groove structure.
In the aforesaid batswing tab light-distribution LED Tunnel Lamp lens, described light distribution structure inner surface is the ellipsoid of depression.Described light distribution structure is exported 130 ° of batswing tab luminous intensity distributions that reach 0 °～180 ° of directions in polar coordinates, 80 ° of reversed cardioid luminous intensity distributions of 90 °～270 ° of directions with the light luminous intensity distribution that the LED spot light sends.Cause the light fixture rising angle appropriate, the driver is not had significant direct projection and reflected glare, help vehicle safety and pass through the tunnel.
In the aforesaid batswing tab light-distribution LED Tunnel Lamp lens, described concave-convex lens is a light transmittance greater than 90% PC lens.
In the aforesaid batswing tab light-distribution LED Tunnel Lamp lens, described location and fixation hole configurations are a plurality of at grade according to axisymmetric through hole in lens centre or breach.Therefore be difficult for installing makeing mistakes, simple installation helps later maintenance simultaneously.
Compared with prior art, the utility model can make the light fixture rising angle appropriate, and the driver is not had significant direct projection and reflected glare, helps vehicle safety and passes through the tunnel.And because led light source draw-in groove structure, ledge structure is installed the design of ruggedized construction and seal groove structure, and the multiple lens that ensured are installed accurately, firmly, possess the water proof and dust proof ability simultaneously.。

The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described, but not as the foundation to the utility model restriction.
Embodiment.A kind of batswing tab light-distribution LED Tunnel Lamp lens, as shown in Figure 1 to Figure 3, it is a concave-convex lens, comprise light distribution structure 1, light distribution structure 1 bottom is provided with led light source draw-in groove structure 2, light distribution structure 1 outer ring is provided with ledge structure 3 and ruggedized construction 4, and ruggedized construction 4 is provided with location and fixation hole configurations 5, and ruggedized construction 4 bottoms are provided with seal groove structure 6.
Described light distribution structure 1 inner surface is the ellipsoid of depression.The distribution curve flux of its generation as shown in Figure 4.
Described concave-convex lens is a light transmittance greater than 90% PC lens.
