Embodiment Construction

[0025] Such as figure 1 with figure 2 as shown, figure 1 is a cross-sectional view of a lens 100 according to an embodiment of the present invention, figure 2 is based on figure 2 is an optical path diagram of a lens according to an embodiment of the present invention. The lens 100 has a bottom surface 1 , a surface 2 , and a central axis X perpendicular to the bottom surface 1 , and also has a cross section perpendicular to the central axis X. On the bottom surface 1 of the lens 100, a recessed area 3 is raised, such area is used to accommodate a light source which can be implemented as an LED chip, so that, by virtue of the surface of the recessed area 3 as the incident surface 4, the light from the light source can be injected into the lens. Wherein, the recessed area 3 can be designed to have a hemispherical, semi-elliptical or conical contour, but not limited to these forms of contours, other contours that can achieve similar effects can be designed as the contour...

Abstract

The invention relates to a lens. The lens comprises a bottom surface and a surface sticking out from the bottom surface; a concave area is defined in the center of the bottom surface; the surface of the concave area forms an incident plane; the surface comprises a first refracting surface, a first reflecting surface, a second refracting surface and a second reflecting surface, wherein first light from a light source is emergent after being refracted by the first refracting surface; second light from the light source is emergent after being reflected by the first reflecting surface and refracted by the second refracting surface; third light from the light source is reflected by the first reflecting surface and the second reflecting surface, and then, is emergent after being refracted by the second refracting surface. Moreover, the invention also designs an illuminating device using the lens.

Description

technical field [0001] The invention relates to a lens and an illuminating device comprising the lens. Background technique [0002] Among the existing lighting devices, quite a few have adopted LED lighting technology, which utilizes LED chips to form lighting effects similar to halogen lamps or incandescent lamps. However, the cost of lighting devices matching LED technology is often higher than that of halogen lamps or incandescent lamps, so the use of LED lighting devices is limited to a certain extent. In order to realize the reduction of unnecessary expenses and achieve economic advantages brought about by reducing costs, it has become a development trend to use new LED technology on the old lighting device platform with economic advantages. Contents of the invention [0003] In order to solve the above technical problems, so that new LED technology can be applied to the platform of the old lighting device, and to achieve a lighting device similar to or the same as ...
