Description

Technical Field

[0001] The utility model belongs to the technical field of LEDs and relates to a light distribution structure of a patch LED of a leather-wire lamp string. Background Art

[0002] In the production process of general leather string lights, UV glue is dripped on the front and back sides of the SMD LED lamp beads and cured by UV light for waterproofing, as described in Patent I Announcement No. CN 307131126 S. Figure 1 As shown, Figure 2 This is the relationship between the luminous angle and luminous intensity of the SMD LED lamp beads of Patent I;

[0003] The luminous angle of the SMD LED lamp bead is 120°, and the light beam is evenly emitted to the surrounding area. Therefore, the surface brightness of the lamp bead cannot reach the luminous effect of the plug-in lamp bead with the same power.

[0004] In Patent II Announcement No. CN 216619427 U and Patent III Announcement No. CN 216591187 U, it is mentioned that decorative fasteners are used to convert the plane luminous effect into the luminous effect of plug-in lamp beads. Figure 3 This is a view of Patent II; Figure 4 This is the view of Patent III; however, this fastener rotates the lamp bead 90 degrees. The light beam at the top of the fastener is the weakest part of the SMD LED lamp bead. The fastener emits the strongest light on the front 1 of the SMD LED lamp bead, the light on the side wall 2 of the LED lamp bead is weaker, and the light on the back 3 of the LED lamp bead is extremely weak. In addition, there is an additional wire blocking the light. In this way, one side of the fastener is bright and the other side is dark, and the light in the middle is weak. The overall effect is quite different from the lighting effect of the plug-in lamp bead. Utility Model Content
