Embodiment Construction

[0033] 1-4 and 9 illustrate the LED device 10 for illuminating toward the preferred side 36 in a downward direction 48 and an outward direction 49. LED device 10 includes: a mounting board 12; an LED package 14 on the mounting board having a primary lens 16 having a central axis 18; and a secondary lens member 20 positioned above and between the primary lens 16 The light path 22 is established. Such as figure 1 and figure 2 As shown, mounting plate 12 is connected to heat sink 54 . One or more (typically several) LED packages 14 are arranged on the mounting board 12 to form a so-called LED module 58 . One or more LED modules 58 are used as various innovative luminaires.

[0034] Such as image 3 As shown in , a shielding member 24 in the form of a layer is positioned over the mounting board 12 , the LED package 14 and the secondary lens member 20 . The shield member 24 has a shielded portion 26 and a substantially planar non-shielded portion 28 around it, as seen in FI...

Abstract

The invention provides LED (Light-Emitting Diode) illumination equipment with a baffle. The LED illumination equipment with the baffle is used for illuminating a preferable side along downward and outward directions. The LED equipment comprises a layer-formed shield component located above an LED capsulation part and a secondary lens component; the shield component is equipped with a shield part and a non-shield part which is approximately flat around. In a preferable embodiment, the shield part extends above one part of a lens part of the secondary lens component. The shield component is preferably fixed by a cover relative to the secondary lens component, a main lens and the LED capsulation part; the shield component is preferably clamped between the cover and a flange of the secondary lens component.

Description

technical field [0001] The present invention relates generally to the field of lighting systems and more particularly to a lighting device for illuminating an area with a predetermined pattern of light intensity using LED (Light Emitting Diode) sources towards a preferred side. Background technique [0002] There is a continuing need for low-cost and energy-efficient lighting devices. LEDs provide an energy-efficient light source, and advancements in LED technology over time are delivering higher efficiencies. One advantage of using LEDs as light sources is simply that the small size of such light sources translates into low material usage in luminaires incorporating such light sources, with attendant cost benefits. [0003] Preferred performance requirements for lighting systems for various uses relate to the degree of freedom to "spill light" in undesired illuminated areas. For example, it is preferred that road and parking lot lighting systems have an excellent light di...
