Abstract
An LED tunnel lamp lens is composed of a module upper end face and a module lower end face which are fixedly connected. A plurality of composite curvature optical modules composed of upper optical curved surfaces and lower optical surfaces are arranged between the module upper end face and the module lower end face, each composite curvature optical module is a horn-shaped shell which is provided with an inner cavity and gradually expands from the bottom to the top, the upper end face of each composite curvature optical module is a non-curvature optical curved surface, the side face of each composite curvature optical module is an outward-convex arc-shaped transition face, and LED lamp beads are arranged in the inner cavities of the composite curvature optical modules. According to the LED tunnel lamp lens, dispatch of a light source is reasonably distributed according to the specificity of tunnel lighting, tunnel lamps with SMD small power light sources are used for conducting light distribution dispatch, light distribution curves are designed for the angle of emergent light of the lamp beads, optical reflecting is increased, so that light loss is reduced, and the light energy utilization efficiency of the LED tunnel lamps is greatly improved.
Description
Technical field
The present invention relates to the LED lighting technical field, be specifically related to the LED tunnel lamp lens of a kind of LED Tunnel Lamp secondary light-distribution special use.
Background technology
In recent years, domestic Illumination Enterprise exchanges, actively improves independent research and development capacity by external cooperation, has greatly promoted the development of China LED illumination.Wherein the energy-conservation research of LED Tunnel Lamp has had great breakthrough, has not only improved LED light source efficiency, and, by the design studies to the LED light fixture, the overall efficiency of LED Tunnel Lamp is improved.Very little, the approximate spot light of light-emitting area due to LED lamp pearl, short distance only has certain brightness very high, other direction is but very dim, need to set up special luminous intensity distribution setting, yet Tunnel Lamp is not through professional luminous intensity distribution design mostly, just simply street lamp lens is brought and is applied directly on Tunnel Lamp, indirectly wasted a lot of light, optical energy utilization efficiency is lower, light loss is large, beaten very heavy discount on practicality, along with the continuous lifting of society to the energy and light modulation understanding, also in the urgent need to a kind of lens that can solve this class problem.
Summary of the invention
The invention provides a kind of LED tunnel lamp lens, the problem that optical energy utilization efficiency is low, light loss is large existed to solve prior art.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of LED tunnel lamp lens, by module upper surface and module lower surface, be formed by fixedly connecting, some composite curvature optical modules that consist of upper optical surface and lower optical surface are set between module upper surface and module lower surface, the composite curvature optical module is the horn-like housing that a white background section with inner chamber upwards is flaring, the upper surface of composite curvature optical module is non-curvature optical surface, the side of composite curvature optical module is the arc transiting surface of evagination, and pearl is built in the inner chamber of composite curvature optical module the LED lamp.，
Above-mentioned upper optical surface and lower optical surface are two high light faces, and the module upper surface is dull surface, play the effect of auxiliary leaded light, and the module lower surface is frosting.
Above-mentioned upper optical surface and lower optical surface select the anti-UV polymer plastic glue material of high transmission rate to be made.
LED street lamp lens module operation principle of the present invention is, the light that LED light source sends changes transmission direction by lower optical surface, then by upper optical surface, launch, the light more than 95% is derived by the composite curvature optical module, and all the other light project road surface after the reflection of module lower surface.
The particularity that the present invention is directed to tunnel illumination is carried out the scheduling of reasonable distribution light source, for the Tunnel Lamp that adopts the SMD low-power light source carries out the lighting allotment, to the angle design distribution curve flux of lamp pearl emergent light, by increasing optical reflection, reduce light loss, greatly improved the optical energy utilization efficiency of LED Tunnel Lamp.
