Abstract
The invention discloses a new LED lens. A plurality of LED lights are arranged on a circuit board in an array mode; the LED lens used is as follows: a plurality of light-focusing curved surfaces are arranged on a planer transparent board, each light-focusing curved surface corresponds to an LED light to form a planar cellular condenser lens. As the number of the LED lights is too much, the formed light source is a planer light source, therefore, the focusing consistency is poor, and meanwhile, the adopted LED lights are all low-power lights, thus the illumination of the LED lights is limited. The planar cellular condenser lens is difficult to focus on consistency, and can be seen cellular light spots with poor visual effect.
Description
Technical field
The present invention relates to a kind of optical equipment, particularly a kind of New LED lens.
Background technology
Existing LED signal lamp, what adopt is that array way is arranged a plurality of LED lamps on circuit board, and its employed New LED lens is to be provided with a plurality of optically focused curved surfaces on the light-passing board of plane, the corresponding LED lamp of each optically focused curved surface promptly constitutes the cellular condenser in plane.Because the number of LED lamp is too many, the light source that is constituted is an area source, and therefore, the uniformity of focusing is poor, and simultaneously, the LED lamp of employing is small light, and makes its brightness extremely limited.The cellular condenser in plane is difficult to accomplish the uniformity that focuses on, can see cellular hot spot, poor visual effect.
Summary of the invention
Purpose of the present invention just provide a kind of novel structure, volume little, apart from the good New LED lens of Jiao's property, it obviously reduces vignette, significantly improves spotlight effect.
The objective of the invention is to realize by such technical scheme, the outer surface of its its lens is provided with a plurality of annular grooves concentric with minute surface, described annular groove enlarges from inside to outside gradually, and it is characterized in that: the inner surface of described lens is the semicircle arcuation, is provided with the optically focused ring at the outer surface of lens.Described optically focused ring is the optically focused curved surface.
Because inner surface adopts dome shape, be provided with the optically focused curved surface at the minute surface center of outer surface simultaneously, so shortened focal length, significantly reduced vignette, improved spotlight effect, under equal light source condition, its brightness is original more than 2 times.
Owing to adopted technique scheme, the present invention to have the advantage of with low cost, novel structure, good condensing performance, use it obviously to reduce vignette, significantly improved spotlight effect.
Description of drawings
Description of drawings of the present invention is as follows:
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the vertical view of Fig. 1.
The specific embodiment
The invention will be further described below in conjunction with drawings and Examples:
Embodiment 1: as shown in Figure 1, 2, a kind of New LED lens, the outer surface of its lens are provided with the concentric annular groove 2 of a plurality of and minute surface 1, and described annular groove 2 enlarges from inside to outside gradually, it is characterized in that: the inner surface of described lens is the semicircle arcuation, is provided with the optically focused ring at the outer surface of lens.
Fast optically focused ring is an optically focused curved surface 3.
Because inner surface adopts dome shape, be provided with optically focused curved surface 3 at minute surface 1 center of outer surface simultaneously, so shortened focal length, significantly reduced vignette, improved spotlight effect, under equal light source condition, its brightness is original more than 2 times.
In order to make spotlight effect better, the number of described annular groove 2 is 5-7.
Claims (3)
1. New LED lens, the outer surface of its lens is provided with a plurality of (2) annular grooves concentric with (1) LED minute surface, and described (2) annular groove enlarges from inside to outside gradually, and it is characterized in that: lens are the semicircle arcuation, in the appearance portion of lens the setting of optically focused ring are arranged.
2. New LED lens as claimed in claim 1 is characterized in that: described optically focused ring is (3) LED optically focused curved surface.
3. New LED lens as claimed in claim 1 is characterized in that: the number of described (2) annular groove is 5-7.
