Technical Field

[0001] The utility model relates to the technical field of LED indicator lights, in particular to an anti-scattering structure of a patch LED indicator light. Background Art

[0002] Light-emitting diodes, abbreviated as LEDs, are made of compounds containing gallium (Ga), arsenic (As), phosphorus (P), nitrogen (N), etc. They can radiate visible light when electrons and holes recombine. Therefore, they can be used to make light-emitting diodes, which are used as indicator lights in circuits and instruments, or to form text or digital displays. LED lamps have low power consumption and strong light. When used as indicator lights, in order to avoid interference from different light colors, each lamp is generally isolated.

[0003] In the prior art, due to the matching gap between the upper shell and the PCB board, it is inevitable that the light of the LED lamp in the grid will be exposed and scattered, thereby affecting the light color display of the LED lamp next to it, and seriously affecting the indication effect.

[0012] Preferably, the installation groove is specifically an inverted trapezoidal platform structure, a mounting plate is fixedly connected through the bottom side of the inner wall of the installation groove, and the lampshade is connected through the middle part of the mounting plate.

[0013] Preferably, an internal threaded ring is fixedly passed through the interior of the mounting plate, the lampshade comprises a sleeve ring and a hollow hemispherical cover, a sleeve hole is passed through the top of the hollow hemispherical cover, and the hollow hemispherical cover is connected to the interior of the sleeve hole through the sleeve hole.

[0014] Preferably, the inner threaded ring is threadedly connected with an outer threaded ring, and a UV lens is fixed through the inner threaded ring. The diameter of the UV lens is equal to the diameter of the sleeve hole on the top side of the hollow hemispherical cover.

[0015] The beneficial effects of the utility model are as follows: the heat sink increases the contact area between the outer side of the L-shaped heat conducting plate and the air, which can conduct the heat generated on the circuit board and achieve an effective heat dissipation effect; under the effect of the reflective film, the lamp tube irradiated by the SMD LED lamp can be reflected to a specific direction, thereby reducing stray light; the sleeve hole on the top of the hollow hemispherical cover can reduce the light source of the SMD LED lamp bead, making the irradiated lamp tube more concentrated; and then in conjunction with the UV lens, the focusing effect can be further improved, making the light source more uniform and reducing stray light.
