Embodiment Construction

[0036] figure 1 A three-dimensional perspective view of a lens according to a first embodiment of the invention is shown. It can be seen from the figure that the lens has a bottom surface 1 and an exit surface 2 raised on the bottom surface 1 . A recessed area 3 is formed in the center of the bottom surface 1 , and the surface of the recessed area 3 forms an incident surface 4 , where the light source (not shown) of the LED lighting device is disposed. It can be further seen in the figure that the incident surface 4 includes four first, second, third and fourth concave portions 4a1, 4a2, 4a3, 4a4 that are recessed away from the light source, and the adjacent first, second, third and The fourth concave surface parts 4a1, 4a2, 4a3, 4a4 transition smoothly, wherein the first, second, third and fourth concave surface parts 4a1, 4a2, 4a3, 4a4 respectively project a butterfly-wing tip-shaped profile in the bottom surface 1 ( see figure 2 ). In addition, adjacent first, second, ...

Abstract

The invention relates to a lens for a light-emitting diode (LED) lighting device, which is provided with a bottom face (1) and an emergent face (2) protruding from the bottom face (1). A concave area (3) is formed in the middle of the bottom face (1), an incidence face (4) is formed on the surface of the concave area (3), and a light source of the LED lighting device is arranged in the concave area (3). The incidence face (4) comprises at least three concave surface portions (4a) recessing towards the position far away from the light source, adjacent concave surface portions (4a) are transited smoothly, and the at least three concave surface portions (4a) respectively project outlines in shapes of butterfly wing apexes on the bottom face (1). In addition, an LED lighting device with the lens is provided.

Description

technical field [0001] The invention relates to a lens for an LED lighting device. In addition, the present invention also relates to an LED lighting device having the above-mentioned type of lens. Background technique [0002] Due to the continuous improvement of people's lighting requirements and the increasing awareness of environmental protection and energy saving, people are more and more willing to use LED lighting devices as light sources. This is because LED lighting devices have a long service life, high luminous efficiency and low energy consumption. consumption. In a place similar to a gas station, since it is usually open 24 hours, the low energy consumption of the LED lighting device itself can greatly reduce the operating cost of the operator. At the same time, due to its unique explosion-proof performance, LED cold light source is more suitable for use in places such as gas stations that require high explosion-proof performance. [0003] Typically, LED ligh...
