Embodiment

Below in conjunction with accompanying drawing the utility model is further described.

embodiment one.

A kind of LED lens module of present embodiment; As shown in Figure 2, it comprises lens carrier 1, a plurality of lens monomer 2, and lens carrier 1 passes through the integrated through injection molding moulding with lens monomer 2 by Merlon; After this LED lens module moulding is transparent, can make the transmitance of light higher.Said lens carrier 1 is provided with the supporting and space 3 of a plurality of hollows; Thereby make illustrated lens carrier 1 become the rectangular frame of a plurality of array arrangements; Said lens carrier 1 is provided with the linking arm 4 that stretches into said supporting and space 3; Said lens monomer 2 is connected with said lens carrier 1 through said linking arm 4, and when lens carrier 1 was fitted with LED wiring board or led support, air can be overflowed from the supporting and space 3 of hollow; Avoid air to be closed between lens carrier 1 and LED wiring board or the led support, thereby avoided lens carrier 1 to form bulge.On the other hand; The utility model has reduced the area of lens carrier 1; Only need to consume less material thereby making lens module is made, reduced cost, and lens monomer 2 and lens carrier 1 have been coupled together through linking arm 4; Lens carrier 1 is not yielding, and lens monomer 2 can accurately be located.
