[0002] SMD LED, also known as SMD LED, is a simple lamp. Its luminous principle is to pass current through compound semiconductors. Through the combination of electrons and holes, the excess energy will be released in the form of light to achieve the luminous effect. When using SMD lamp beads, a lens is needed to diffuse the light, reduce glare, and provide a soft and uniform light effect.

[0003] For example, the utility model with publication number CN206742275U discloses a patch-type infrared LED lamp bead. This utility model uses molding to first encapsulate a rectangular or quadrangular pyramidal package on the outside of the infrared chip. The top of the package is flat, and a package lens is molded above the top plane. The height of the package and the size of the package lens can be adjusted according to the required light-emitting angle, which provides good controllability of the light-emitting angle. However, after long-term use, some of the packaging material of the lamp bead will volatilize some harmful gases in high-temperature environments. If these gases continue to accumulate inside the lens, they will cause fogging, which will affect the lens's light transmittance.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a lens with an exhaust hole is provided. Utility Model Content

The outer side of the lens body 1 is connected to a lug 2, and the top of the lens body 1 is provided with a concave portion 3. The diameter of the lens body 1 is 12.5mm, and the height of the lens body 1 is 4.69mm. This lens can be compatible with 3 cm and 2.5 cm panel lights, and the design size is 12.5mm. It is smaller in size than the mainstream 13.5mm lens, lighter in total, and the width of the aluminum substrate can also be made narrower. The cross-section of the concave portion 3 is arc-shaped, and the concave portion 3 is The center line coincides with the center line of the lens body 1. The design of the concave portion 3 makes the light output angle larger, the minimum OD value can be 20m, the light spot is more uniform and soft, and when multiple lamp beads are arranged and the OD is the same, the light spots are more evenly connected, and the uniformity of the whole plate is higher than that of the lens without concave design. The outer end of the bottom of the lens body 1 is connected with a bonding portion 4, which is in an arc shape and is equidistantly distributed around the bottom of the lens body 1. Since the position of the bonding portion 4 is far from the center of the lens body 1, it is not easy to be glued together during bonding. During the installation process, it can also effectively prevent glue from flowing onto the lamp beads. The avoidance groove 5 is provided at the outer end of the bottom of the lens body 1. There are three avoidance grooves 5, and the avoidance grooves 5 correspond to the lugs 2 one by one. The avoidance groove 5 is used as an ejector pin position, which can effectively avoid the problem of uneven installation of the lens body 1 due to the ejector pin cloak. It can also be used as a lens exhaust hole for exhaust, which can effectively improve the problem of harmful gas atomization caused by long-term lighting of the lens and affecting the light transmission effect. The outer side of the lug 2 is obtuse-angled, and the lugs 2 are equidistantly distributed around the outer side of the lens body 1. The lens body 1 can be conveniently taken out through the lug 2, and the lug 2 corresponds to the direction of the avoidance groove 5, so the position of the avoidance groove 5 can be quickly controlled during the installation process to align the ejector cloak. A limiting groove 6 is provided in the center of the bottom of the lens body 1, and a groove 7 is provided in the center of the interior of the lens body 1. The limiting groove 6 is circular, and the diameter of the limiting groove 6 is 4.4 mm. The groove 7 is a round-headed cone, and the center line of the groove 7 coincides with the center line of the lens body 1. The limiting groove 6 can be used as a structure for clamping the lamp beads to avoid lens deviation.

[0023] In summary, when using the lens with exhaust holes, first Figure 1 、 Figure 2 and Figure 3As shown in the structure, during installation, the installation position is first limited quickly by the limiting groove 6, and the avoidance groove 5 is used as the ejector position, which can effectively avoid the uneven installation of the lens body 1 due to the ejector cloak. Then, the bonding part 4 is glued and fixed, and the bonding part 4 is away from the lamp bead to avoid glue flowing onto the lamp bead. Finally, during use, the design of the concave portion 3 makes the light output angle larger, the connection between the light spots is more uniform, and the harmful gases generated after long-term lighting can also be discharged through the avoidance groove 5 to avoid gas atomization affecting the light transmission effect.
