Description

Integrated optical combined lens

Technical Field

The invention belongs to the field of lighting engineering, and particularly relates to an integrated optical combined lens.

Background

The optical lens is mainly used for condensing and guiding light of light source series products, a light distribution curve is designed according to angles of different emergent light, light loss is reduced by increasing optical reflection, and light efficiency is improved.

Different lens angles are selected according to different application scenes, and the street lamp lens is generally a lens with an angle of 140 degrees multiplied by 60 degrees; the projection lamp for tall buildings and mountain illumination needs a lens with a small angle, such as 8 degrees or 10 degrees; the wall washer needs a lens of 20 to 60 degrees.

The optical lens may be divided into a single optical lens and a unitary optical lens according to a mounting method. The single optical lens has the main advantages that the optical lens is independent, the size can be freely designed in different scenes when the lamp is designed, the size of a mold required by production is small, and the mold opening cost is low. The main disadvantages are that each optical lens needs to be mounted, the common mounting scheme is to directly adhere the lens to the lamp, which wastes labor, the cost of a single optical lens is high, and the lamp is also provided with a separate waterproof cover. If the optical lens with heavy weight is encountered, a bracket needs to be additionally designed for installation, and the cost is high in mass production. The single optical lens is only suitable for the lighting products with less optical lenses or irregularly arranged light sources, and is not suitable for lamps produced in large scale. The integrated optical lens consists of a plurality of optical lenses, has the main advantages of quick and convenient installation, and has the main disadvantages of larger size of a mold required for production, high mold opening cost, fixed lens type and incapability of free combination; and the quantity of the LED lamp beads of some lamps is less than that of the lenses, so that the lenses have vacant positions and waste is caused.

Disclosure of Invention

The invention aims to provide an integrated optical combined lens which is low in mold cost, flexible in lens combination and wide in application occasions.

The technical scheme for realizing the purpose is as follows:

the utility model provides an integral type optics combination lens, includes the translucent cover and installs the monomer optical lens in the translucent cover, the translucent cover includes that the border of transparent bottom plate and transparent bottom plate upwards extends and seamlessly encloses synthetic cover wall, and cover wall top face is equipped with the recess of installation sealing washer, is equipped with the mount pad that a plurality of is used for installing optical lens on the transparent bottom plate, and monomer optical lens bottom is equipped with the connecting device who corresponds with the mount pad, monomer optical lens combines to be fixed on the transparent plate through its connecting device and mount pad.

Further, the connecting device and the mounting seat are combined into a threaded combination.

Further, the connecting device and the mounting seat are combined into a snap-fit combination.

When the integrated optical combined lens is used, the single optical lenses are combined into a whole, a lens support does not need to be designed independently, the number and the distribution of the mounting seats can be determined according to the number and the distribution of the lamp beads on the lamp panel, scenes needing different illumination angles can be adapted by replacing the inner single lens, the mounting time and the cost of the mold opening and the support are saved, when the number of the LED lamp beads of the lamp is less than that of the lens, the lens can not be mounted at the position without the lamp beads, and the cost of the lens is saved.

Detailed Description

The present invention will be described in detail with reference to examples.

With reference to figures 1 to 3 of the drawings,

an integrated optical combined lens comprises a transparent cover 1 and a single optical lens 2 arranged in the transparent cover 1, wherein the transparent cover 1 comprises a transparent bottom plate 1-1 and a cover wall formed by seamlessly enclosing the transparent bottom plate 1-1 and extending upwards along the edge, a groove 1-2 for installing a sealing ring 4 is arranged on the top end face of the cover wall, a plurality of installation bases 1-10 for installing the optical lens 2 are arranged on the transparent bottom plate 1-1, a connecting device 2-1 corresponding to the installation bases 1-10 is arranged at the bottom of the single optical lens 2, the single optical lens 2 is combined and fixed on the transparent plate with the installation bases 1-10 through the connecting device 2-1, in the embodiment, the connecting device 2-1 and the installation bases 1-10 are combined in a buckling mode, wherein the connecting device 2-1 is a circular boss at the bottom edge of the optical lens 2, the mounting base 1-10 is composed of four elastic concave buckles, when the bottom of the optical lens 2 is inserted between the four elastic concave buckles, the concave buckles are buckled on the upper end face of the annular boss, and the optical lens 2 is further fixed on the transparent bottom plate 1-1. The snap-fit manner facilitates quick and nondestructive installation and replacement of the optical lens 2.

When the integrated optical combined lens is used, the optical lens 2 is firstly fixed on the transparent bottom plate 1-1, different types of optical lenses 2 can be selected according to requirements, then the waterproof sealing ring 4 is arranged in the groove 1-2, and then the top end face of the cover wall is fixed on the heat dissipation body 3 in a screw or glue bonding mode and the like, so that the integrated optical combined lens is installed.

The following are the main steps for removing and replacing the optical lens 2,

for the installed integrated optical combined lens, the corresponding concave button for fixing the optical lens 2 is poked by hands or tweezers, and the optical lens 2 is taken out, so that the disassembly is completed;

another optical lens 2 is arranged between the corresponding concave buttons of the transparent cover 1 through the annular boss, and the replacement is completed.
