Abstract

An LED even-light street lamp relates to LED illumination equipment, in particular to the technical field of LED even-light illumination. The LED even-light street lamp is provided to solve the problems that existing LED illumination street lamps are low in illuminating brightness and uneven in light. The LED even-light street lamp is technically characterized in that an illumination module formed by integrating more than two LED even-light chips is mounted in a space formed by a refection shade and a lamp shade, and the refection shade and the lamp shade are placed in a top cover in sequence and are fixed through a panel. An LED illumination light evener and an LED are packaged by an epoxy resin packager and form the LED uniform-light chips in a combined manner, the LED is composed of an LED chip, a packaging lens, a base, and a reflection cavity. The evenness of illumination of the LED illumination street lamp can be improved greatly, depth of the LED lamp is reduced, and the size of the lamp is reduced. Compared with lamps of the same size and illumination brightness, the amount of LEDs in use is reduced and energy-saving effect is evident.

Description

The equal light path lamp of a kind of LED

Technical field

The utility model relates to a kind of LED lighting apparatus, relates in particular to the equal optical illumination technical field of LED.

Background technology

In recent years, along with led chip technology and Development of Packaging Technology, LED has been widely used on the indoor and outdoor lighting light fixtures such as urban road, square, street, tunnel and desk lamp and electric light.But this LED illuminating lamp has a very big defective: the space angle light intensity different is mutually far short of what is expected; It is very inhomogeneous to distribute, and promptly the zonal ray in wide-angle is rarer, and the low-angle zonal ray is closeer; The point of vertical light intensity is the strongest, so its light intensity is confined to very little scope very much.In order to change the problem of this illumination unevenness, many manufacturers adopt the method for many boundary reflections mirror to solve this problem, and its effect is limited, and packaging volume is excessive; The manufacturer that has also is employed in and installs Fresnel Lenses on the light fixture additional for obtaining indoor and outdoor lighting relatively uniformly, but technology and complicacy thereof, and all light effect is very unsatisfactory.The present most of developmental research LED of enterprise illuminating street lamp adopts more increases LED quantity, with the LED discharging closely, and according to the LED arranged.Though this certain degree has solved even lighting problem, has also increased the required energy that throws light on, LED discharging simultaneously is very near, also is unfavorable for heat radiation, and its stability will reduce, and after a period of time, the LED intensity of illumination also can descend, and has influence on LED service life.

Summary of the invention

The utility model technical problem to be solved is to overcome above-mentioned existing in prior technology weak point, and a kind of LED is provided equal optical illumination technology, has solved the not high and problem of non-uniform of present LED illuminating street lamp brightness of illumination well.

The technical scheme that the utility model is taked is: the equal light path lamp of a kind of LED; The lamp body that comprises light pole and end fixed thereon; Lamp body is made up of the integrated lighting module of LED light equalizing chip, top cover, panel, reflection shield and lampshade; The integrated lighting module of LED light equalizing chip is installed in the space of reflection shield and lampshade composition, and reflection shield and lampshade are placed in the top cover successively, fix with panel.The LED light equalizing chip is to throw light on all by LED that light device and LED combine through the encapsulation of epoxy encapsulation body; Wherein throw light on equal light device of LED is to have the convergent lens that a plurality of optical surfaces are formed; Claim Fresnel Lenses again; One side is the plane, and another side is a convex surface, and LED is made up of led chip, package lens, pedestal, reflective groove.The integrated lighting module of LED light equalizing chip is the strip modules by the integrated mould barization that is packaged into of plural LED light equalizing chip.

The beneficial effect of the utility model is: improve the uniformity of LED illuminating street lamp illumination significantly, the uniformity can reach more than 94%; Use this LED light equalizing chip that the degree of depth of LED light fixture is shoaled, smaller volume, the processing of LED Design of Luminaires becomes extremely simple; To onesize and light fixture brightness of illumination, use this LED light equalizing chip than using general LED and reduced the LED usage quantity, reduced the required energy that throws light on, further reach energy-saving effect, can improve the reliability of LED street lamp.This utility model is widely used in the illuminations such as urban road, square, street, tunnel.
