Problems solved by technology

[0003] The technical problem to be solved by the present invention is: to overcome the high scrap rate in the production process of the large-size LED lens in the prior art, the quality of the product cannot be guaranteed, and the consumption of raw materials is large, which makes the production enterprise suffer from no profit or loss. Defects that cannot be produced, to meet people's wishes and the market demand for large-size LED lenses, provide a hollow LED lens, the thickness of this hollow LED lens is relatively uniform, and the dimensional tolerance caused by the thermal expansion and contraction of the material itself It is very small, so the pass rate of the product is very high, which improves the quality of the product, reduces the consumption of raw materials, reduces the production cost of the product, increases the profit of the manufacturer, and fundamentally solves the problem that large-size lenses cannot be produced

Embodiment 1

[0025] Embodiment one, such as Figure 1 to Figure 5As shown, a hollow LED lens described in this embodiment has a hollow body 1, and a lens edge 8 is injection-molded on the upper part of the hollow body 1 through integral molding. The lower end of the hollow body 1 has a reserved installation cavity 7 and a lens The lower end surface 9, the reserved installation cavity 7 is connected to the lower end surface 9 of the lens, and the installation cavity 7 is reserved for installing LEDs; the outer side of the hollow body 1 has a light reflection surface 6, and the upper end of the hollow body 1 has a light-emitting split top surface 4 The hollow inner cavity wall of the hollow body 1 is composed of four light-emitting dividing surfaces 3 and five inner wall dividing surfaces 5 from bottom to top. In other embodiments of the present invention, the light-emitting dividing surfaces 3 and inner wall dividing surfaces 5 are not Limited by the above data; every two adjacent inner wal...

Embodiment 2

[0026] Embodiment two, such as Image 6 As shown, a kind of hollow LED lens described in this embodiment, compared with Embodiment 1, differs in that the five inner wall dividing surfaces 5 in Embodiment 1 are respectively in the shape of a cylindrical inner wall surface, while Embodiment 2 The five inner wall dividing surfaces 5 are in the shape of the side surface of rounded table respectively, and the diameters of the five inner wall dividing surfaces 5 on the middle section parallel to the horizontal plane are in the hollow cavity of the hollow body 1 from bottom to top. are sequentially increasing. The diameters of the five inner wall dividing planes 5 on the middle section parallel to the horizontal plane are 20 mm, 28 mm, 36 mm, 44 mm, 52 mm from bottom to top in the hollow cavity of the hollow body 1 . When the five inner wall dividing surfaces 5 are in the shape of the side surface of the rounded table, the light emitting surface of the hollow LED lens is composed o...

Abstract

The invention discloses a hollow LED lens, and belongs to the field of optical lenses for LED illumination. The hollow LED lens comprises a hollow body, wherein a lens edge is formed in the upper part of the hollow body through injection molding in an integrated molding manner; a reserved mounting cavity and a lower lens end surface are formed at the lower end part of the hollow body, and the reserved mounting cavity is connected with the lower lens end surface; a light reflecting surface is formed at the outer side part of the hollow body; a light outgoing division top surface is formed at the upper end part of the hollow body; a hollow inner cavity wall of the hollow body comprises a plurality of light outgoing division surfaces and a plurality of inner wall division surfaces from the bottom up, and every two adjacent inner wall division surfaces are connected with one light outgoing division surface; a light outgoing division bottom surface is formed at the lower end part of the hollow cavity of the hollow body and connected with one adjacent inner wall division surface, and the light outgoing division top surface is connected with one adjacent inner wall division surface. According to the hollow LED lens, the thickness of the lens is uniform, the production can be facilitated, and the product rejection rate, the raw material consumption and the product cost can be reduced.

Description

technical field [0001] The invention relates to the technical field of optical lenses for LED lighting, in particular to a hollow LED lens. Background technique [0002] With the continuous development of semiconductor materials and processes, light-emitting diodes (LEDs) are gradually replacing traditional light sources and becoming a new generation of light sources. Light-emitting diodes used as light sources for lighting have the advantages of high efficiency, energy saving, environmental protection, flexibility, durability and safety. In LED lighting fixtures, in order to obtain proper light distribution and brightness, it is often necessary to install an LED lens on the LED bead. In the actual lighting process, such as projection lamps, reading lamps, venue lighting, indoor lighting, etc., people require strong light brightness, which requires a large-size lens that matches it, that is, large-size There is a great market demand for lenses. However, since the LED len...
