Description
Technical field
The present invention relates to LED lighting technical field, particularly a kind of directional lighting LED lamp of large light-emitting area.
Background technology
LED due to have energy-saving and environmental protection, can be light-operated, the lot of advantages such as solidification, long-life, be widely used in the every field such as public illumination, office and the room lighting in city.
Existing traditional BR type lamp, belongs to directional lighting, by the reflectance coating reflection of cell-shell side, by whole end face printing opacity, forms directional lighting lamp certain angle and that light-emitting area is large.The LED lamp of type as an alternative, accomplishes and the similar profile of traditional lighting, and realizes the luminous and uniform directional lighting lamp of brightness of whole end face, is the design focal point of this series products and the direction of pursuit.
As everyone knows, LED itself is the light source that belongs to directional lighting, but say its directional lighting, just say that its light has certain orientation, different with the concept of the directional lighting of lighting field, directional lighting refers within the scope of the solid angle of π sr, to have 80% and with glazing output, now some BR lamps on the market, mainly contain following characteristics: the first, reduce light-emitting area, to meet the requirement of directional lighting; Shortcoming is to compare form with traditional LED bulb light-emitting area to differ very large.The second, increase light-emitting area, more to approach traditional LED bulb; Shortcoming is the requirement that is not easy to realize directional lighting.

As preferably, together with this reflection shield is screwed in radiator body.
For making heat dissipation channel keep unimpeded, as preferably, the upper end of reflection shield extends out the boss that forms an annular, leaves gap so that heat dissipation channel maintenance is unimpeded between described boss and radiating fin upper end.
As preferably, described directional lighting LED lamp also comprises the lampshade being connected with reflection shield, and described lampshade and reflection shield form an enclosure space.
As preferably, described lampshade is connected by buckle form with reflection shield.
As preferably, between Fresnel lens and LED light source, leave the gap that is greater than 2mm; When can making like this intermediate rays gather, also make marginal portion can spill some light, light is arranged more reasonable.
Compared to prior art, the present invention arranges a secondary optics device, this secondary optics device is a Fresnel lens, it carries out luminous intensity distribution to the lighting angle of LED light source module, the luminous intensity distribution of approximate lambert's body of LED is drawn in to centre, again by lampshade to light filter, thereby can realize a kind of simple in structure, with the equally directional lighting LED lamp of whole top light emitting of conventional light source.
