Description

Technical Field

[0001] The utility model relates to the technical field of LED lighting, in particular to a glass lens module of an LED lamp. Background Art

[0002] In order to achieve light distribution, the LED module needs to install a lens on the light output surface of the light source. The traditional lens is made of PC material. The PC lens tends to turn yellow after long-term outdoor use, resulting in reduced light efficiency of the LED module. To solve this problem, the prior art uses a piece of UV-resistant glass installed above the lens of the LED module, such as authorization announcement number CN217603910U. Although this method solves the problem of yellowing of the lens, the additional glass not only increases the material cost, but also makes the entire module heavier.

[0003] Alternatively, the PC plastic lens is replaced with a glass lens. In order to achieve sealing performance, a glass glue groove is opened on the radiator mounting surface. After the glue is poured into the glass glue groove, the glass lens covers the top of the glass glue groove, and the frame is used to further press and seal the outside of the glass lens, such as announcement number CN220911153U. Although this method solves the problem of yellowing of the lens, when operating the frame to press the outside of the glass lens, excessive force may damage the outside of the glass lens, causing the glass to crack due to stress, making the sealing performance of the LED module invalid.

[0025] Please refer to Figure 1-Figure 6 A glass lens module for an LED lamp comprises a heat sink 1, a lamp board 2, a glass lens 3, a pressing plate 4 and a sealing ring 5.

[0026] The lamp board 2 is provided with several groups of lamp bead clusters, each of which is composed of 4 LED lamp beads. The lamp beads in the lamp bead cluster are arranged in a cross pattern and the lamp bead clusters are distributed in an array pattern. A wire hole is provided in the middle of the lamp board 2, and several first screw holes are distributed in the middle of the lamp board 2 along the long side direction.

[0027] The heat sink 1 is provided with a heat sink substrate 11, and a plurality of blind holes 13 that are not drilled are distributed in the middle of the surface of the heat sink substrate 11 along the long side direction. The lamp board 2 is fixed to the heat sink substrate 11 through the first screw hole and the blind hole 13. The blind hole 13 can prevent water from entering from the bottom of the heat sink substrate 11. A fixed through hole is provided in the middle of the heat sink substrate 11. After the lamp bead clusters are electrically connected, the cable passes through the wire hole and the fixed through hole, and finally is fixed to the fixed through hole with a cable fixing head. The back of the heat sink substrate 11 is provided with heat sink fins 12 that are perpendicular to the heat sink substrate 11, and the heat sink fins 12 are evenly distributed directly below the lamp bead cluster of the lamp board 2.

[0028] The glass lens 3 includes a plurality of lens bodies 31 and a lens base 32 connected to the lens bodies 31. The lens bodies 31 and the lamp bead clusters are arranged one by one. The edge of the lens base 32 is provided with a plurality of positioning grooves 33. The lens base 32 is also provided with a plurality of screw avoidance cavities, and the screw avoidance cavities are used to avoid the screws fixed in the first screw holes.

[0029] The pressing plate 4 includes a pressing plate body 41, on which two lens mounting positions 42 are arranged. The lens mounting positions 42 run through the upper and lower surfaces of the pressing plate 4. A raised pressure strip 43 is arranged around the lens mounting position 42. The pressure strip 43 surrounds the lens mounting position 42. A glue dispensing groove 44 is arranged on the pressure strip 43. The glue dispensing groove 44 is filled with glue. The edge of the lens base 32 covers the top of the glue dispensing groove 44. The pressing plate 4 is provided with a plurality of positioning protrusions 45, which are arranged on the outer circle of the glue dispensing groove 44. The positioning protrusions 45 are adapted to the positioning grooves 33 in a one-to-one correspondence, so as to facilitate the positioning and installation of the pressing plate 4 and the glass lens 3. A sealing groove 46 is arranged around the periphery of the pressing plate body 41, and the sealing ring 5 is installed in the sealing groove 46. A plurality of second screw holes are distributed around the periphery of the sealing groove 46, and the second screw holes are used to fix the pressing plate 4 on the heat dissipation substrate 11.

[0030] The cross section of the sealing ring 5 is U-shaped.

[0031] During assembly: Step S1, first invert the pressing plate 4, and install the sealing ring 5 into the sealing groove 46; Step S2, fill the glue dispensing groove 44 with glue; Step S3, place the lens body 31 of the glass lens 3 into the lens mounting position 42, and the edge of the lens base 32 is bonded to the top of the glue dispensing groove 44; Step S4, install the light board 2 on the heat dissipation substrate 11 with screws, and fix the cable fixing head; In order to improve production efficiency, steps S1-S3 and step S4 can be performed simultaneously, and step S4 does not have to wait for step S3 to be completed before operating. Step S5, after steps S3 and S4 are completed, fix the heat sink 1 assembled with the light board 2 on the pressing plate 4 with screws, so that the light board 2 is below the glass lens 3; Step S6, invert the assembled LED module and wait for the glue to dry.

[0032] The utility model does not need to wait until the glue in the glue dispensing groove 44 dries up before performing the final product assembly, which can save production efficiency. The glass lens 3 and the pressing plate 4 are fixed by glue to achieve sealing between the two, and then the pressing plate 4 is fixed on the heat dissipation substrate 11. Since the second screw hole on the pressing plate 4 is at a certain distance from the glass lens 3, the pressing force of the locking screw will not act on the glass lens 3, thereby preventing damage to the glass lens 3 during the assembly process, thereby improving the sealing of the LED module.

[0033] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
