Abstract
The utility model relates to an LED light source, particularly to a plane LED lamp light source equipped with a secondary light distributing shade. The LED light source comprises a circuit substrate (1), a plane LED light source (2) and a secondary light distributing shade (3), wherein the plane LED light source (2) is formed by evenly distributing a plurality of small-power LEDs on a plane, the plane LED light source (2) is orderly arranged on the circuit substrate (1), and the secondary light distributing shade (3) is mounted above the plane LED light source (2). The secondary light distributing shade (3) is utilized to uniformly project the rays emitted by the plane LED light source (2) onto the illuminated ground. Compared with the LED electric light source with great power, the illuminated surface is uniform, and the luminous efficiency utilizing rate is high, more ideal light intensity distribution is achieved, and the glare is effectively avoided, and therefore, the driving safety on the road is improved and the ground illuminating requirements are met.
Description
Technical field
The utility model relates to lighting field, is a kind of led light source, is meant a kind of planar LED road-light light-source of being furnished with the secondary light-distribution cover especially.
Background technology
At present, the research of LED lighting engineering reaches its maturity, and all kinds of lighting installations and apparatus have adopted the LED lighting engineering widely.LED not only energy-conservation, the long service life of throwing light on, and it does not adopt the normal noxious material that uses in the common bulb, environmental protection more.But it is strong that the LED illumination is limited to the luminous directive property of self, causes light angle little, and shadow surface is inhomogeneous, is easy to generate dazzle.
Summary of the invention
At the deficiency that prior art exists, the utility model provides light distributing cap that led light source is carried out secondary light-distribution, and is even than the light that like product projects, avoided dazzle, the led light source irradiating angle increases greatly, and the led light source luminous efficiency is improved, thereby reaches the purpose of saving the energy.
Road-light light-source described in the utility model comprises circuit substrate (1), planar LED light source (2) and secondary light-distribution cover (3).Planar LED light source (2) is arranged by many low-power LED uniform planars and is made, diameter is between the 5mm-60mm and reaches the power of 1w-20w, solved because high-power some led light source heating concentrates the life-span of causing to the led light source to shorten and bad phenomenon such as light decay.What planar LED light source (2) was orderly is arranged on the circuit substrate (1), and secondary light-distribution cover (3) is installed on the planar LED light source (2).
Secondary light-distribution cover (3) is the conical shell structure of circular upper part and square lower part, and its upper and lower end face does not all have capping, and the upper surface is circular and to the left side or the right side inclination 15-60 degree of lower end square aperture, the 15-60 degree turns forward.
Planar LED light source (2) go up construction opening forward/the secondary light-distribution cover (3) that is tilted to the left and forward/is tilted to the right, make direct projection led light can to around reflection, the light that planar LED light source (2) is sent evenly projects on the illumination road surface.

The specific embodiment
In a kind of planar LED road-light light-source structural representation of being furnished with the secondary light-distribution cover illustrated in figures 1 and 2, orderly being arranged on the circuit substrate (1) of planar LED light source (2) of arranging and being made by many low-power LED uniform planars, secondary light-distribution cover (3) is installed on the planar LED light source (2), the corresponding planar LED light source (2) of each the light cup in the secondary light-distribution cover (3).
The light that planar LED light source (2) is sent by secondary light-distribution cover (3) throws light on the road surface uniformly.The utility model is even than great power LED spot light plane of illumination, and light efficiency utilization rate height has more increased ray cast and reached better light distribution, thereby and effectively avoid dazzle to improve the road driving security, meet the requirement of road lighting.
