Detailed Description

In order to make the above objects, features and advantages of the present invention more comprehensible, embodiments of the present invention are described in detail below with reference to the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein, as those skilled in the art will be able to make similar modifications without departing from the spirit and scope of the present invention.

It will be understood that when an element is referred to as being "secured to" or "disposed on" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only and do not represent the only embodiments.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

As shown in fig. 1-3, a reflective membrane for lens, including lens 1 and reflective membrane 2, it is a plurality of lens 1 carries out the array and installs on

lamp plate

3, 1 section semicircular in shape of lens, lens 1 with lamp plate 3 is connected one side central point and is put and be provided with and be conical opening 11, lens 1 with lamp plate 3 is connected one side and is the planishing surface, 2 middle parts of reflective membrane be provided with the through-hole 21 of opening 11 intercommunication, reflective membrane 2 from the top down is reflector layer 22, gluing layer 23 and bottom 24 in proper order, reflector layer 21 with the planishing surface butt, gluing layer 23 sets up reflector layer 22 with between the bottom 24. Specifically, in this embodiment, an opening 11 is provided on one side of the lens 1, and a lamp bead (not shown in the figure) is installed by using the opening 11. And, in order to prevent that the light that the lamp pearl produced from overflowing from the plano of

lens

1, 1 plano one end of lens is provided with reflective membrane 2, utilizes reflective membrane 2 to shield the plano of lens 1, prevents that light from overflowing from the plano, leads to the light effect to darken. Specifically, reflective membrane 2 falls into the three-layer, is reflector layer 22, gluing layer 23 and bottom 24 in proper order, and bottom 24 is that light tight material makes, can be so that behind the reflector layer 23 reflection light, penetrate behind lens 1 being hemispherical body and jet out, and light scattering avoids light to concentrate into a branch, and when people looked, can form the round halo around lens 1 for stage lighting effect is gorgeous more, and visual experience is better. It should be noted that, the reflective film 2 is provided with a plurality of through holes 21 communicated with the opening 11, so that the power line of the lamp bead can conveniently pass through the through holes 21.
