Abstract
The utility model relates to an LED light-uniforming traffic signal lamp which is an LED signal lamp device, in particular to the technical field of the LED light-uniforming traffic signal lamp. In the utility model, an LED light uniforming and radiating technology is provided, and the problem that the existing LED light-uniforming traffic signal lamp is low in light radiation brightness and uneven in light is well solved. The LED light-uniforming traffic signal lamp has the technical key points that the LED light-uniforming traffic signal lamp is assembled by an illumination module integrated by more than two LED light-uniforming chips, a light fitting shell and a colored light lamp shade, wherein each LED light-uniforming chip is formed by packaging and combining an LED illumination light-uniforming device and an LED by an epoxy resin package body; the LED illumination light-uniforming device is a convergent lens provided with a plurality of optical surfaces and is also known as a Fresnel lens; and one side of the LED illumination light-uniforming device is a plane, and the other side thereof is a convex curved surface. The LED light-uniforming traffic signal lamp greatly improves the uniformity and the brightness of light emitted by the LED light-uniforming traffic signal lamp, and the LED signal lamp is shallow in depth, small in volume and extremely simple in design and processing; and compared with the signal lamp with the same size and the light radiation brightness, the LED light-uniforming traffic signal lamp uses less LEDs, is remarkable in energy-saving effect, and improves the stability.
Description
Technical field
The utility model relates to a kind of LED changing of traffic lights, relates in particular to all light traffic lights technical fields of LED.
Background technology
In recent years, along with led chip technology and Development of Packaging Technology, LED has been widely used on the traffic signals light fixture of urban road.But this LED traffic lights have a very big defective: ejaculation to penetrate light inhomogeneous, the zonal ray of wide-angle is rarer, and the low-angle zonal ray is closeer, and the point of vertical light intensity is the strongest, bright and just dark more more outward in the middle of so appearance seems, do not meet the traffic lights requirement.In order to change the problem of this non-uniform light, many manufacturers adopt the method for many boundary reflections mirror to solve this problem, and its effect is limited, and packaging volume is excessive; Fresnel Lenses is installed in the also employing that has additional on light fixture, but technology and complexity thereof, and all light effect is very unsatisfactory; The employing that has increases LED quantity, 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, after a period of time, the LED intensity of illumination also can descend, and has influence on LED serviceable life.
Summary of the invention
Technical problem to be solved in the utility model is to overcome above-mentioned existing in prior technology weak point, provide a kind of LED all light penetrate optical tech, solved present LED traffic lights well and penetrated the not high and light problem of non-uniform of luminance brightness.
Technical solution adopted in the utility model is: 2 integrated lighting module, lamp casing and coloured light lampshades of above LED light equalizing chip are assembled into all light traffic lights of LED, wherein 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, LED throws light on all, and the light device 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.The integrated module that is packaged into circle or arrowhead form of LED light equalizing chip is laid in the housing lamp casing transparent surface encapsulation coloured light lampshade along the lamp casing inside surface.
The beneficial effects of the utility model are: improve the uniformity coefficient that the LED traffic lights are penetrated light significantly, uniformity coefficient can reach more than 94%; Use this LED light equalizing chip that the degree of depth of LED traffic signals light fixture is shoaled, smaller volume, LED traffic signals light fixture Design and Machining becomes extremely simple; To onesize and penetrate the signal lamp of luminance brightness, 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, improve the reliability of LED traffic lights.
