Description

Technical Field

[0001] The utility model relates to the technical field of lighting devices, in particular to an LED lamp bead shade. Background Art

[0002] As we all know, LED (light emitting diode) is known as the fourth generation of light source, which has the advantages of long life, high light efficiency and no radiation. The theoretical life of LED exceeds 100,000 hours, the luminous efficiency is as high as 90%, and the energy consumption of the same luminous flux is only 8% of incandescent lamps and 30% of halogen lamps. It has significant advantages of being green and low-carbon. LED has been widely used in the field of lighting around the world.

[0003] As the main lighting equipment of motorcycles or electric vehicles, headlights provide strong protection for the safety of riders during the day or night when the light is insufficient. Existing headlights mainly use halogen lamps as light sources, which reflect light in front of the vehicle through a reflective bowl. Since the halogen light source has lower light efficiency than LEDs, generates more heat, and has a shorter lifespan, and the light utilization rate of the reflective bowl is low, existing automobile headlights generally have problems such as high energy consumption, weak lighting, high heat, and short lifespan (such as easy burning and breaking of the filament), which poses certain safety hazards.

[0004] Due to the significant advantages of LED, multiple LED light strips or LED light groups are currently used in the market to compensate for the problem of headlight lighting effects. However, the heights of LED lamp beads of different types of lamps are different. After searching, the application number CN202020031386. discloses an LED lamp bead shading cover, which uses a shading ring to overcome the poor light type of LED lamp beads such as scattered light and stray light producing virtual light, but the height of the shading ring cannot be adjusted, and it cannot be applied to LED lamp beads of different heights, and the practicality is low. Utility Model Content

[0005] 1. Technical issues to be solved

[0006] In view of the deficiencies in the prior art, the utility model provides an LED lamp bead shading cover, which can adjust the height of the shading and can be suitable for LED lamp beads of different heights, thereby improving practicality.

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an LED lamp bead light shield, comprising a circuit board and an LED lamp bead, a detachable base is arranged on the circuit board and around the LED lamp bead, a light shielding ring is fixedly arranged on the top of the base, a thread is arranged on the outer wall of the light shielding ring, a nut is connected to the bottom of the outside of the light shielding ring through a thread, a sleeve is installed on the top of the outside of the light shielding ring, a connecting block is fixedly arranged on the inner wall of the top of the sleeve, a light shielding film is fixedly connected to the inner wall of the connecting block, and the bottom end of the light shielding film is fixedly connected to the base.

[0009] Furthermore, the circuit board and the base are detachably connected by snapping in, plugging in, or screwing.

[0010] Furthermore, the material of the shading film is elastic material.

[0011] Furthermore, the outer wall of the light-shielding film and the inner wall of the light-shielding ring abut against each other.

[0012] Furthermore, the sleeve and the light shielding ring are slidably connected.

[0013] (III) Beneficial effects

[0014] Compared with the prior art, the utility model provides an LED lamp bead shade, which has the following beneficial effects:

[0015] The LED lamp bead light shield is provided with a nut, a sleeve, a connecting block and a light shielding film. The height of the sleeve can be adjusted by rotating the nut. The light shielding film is made of elastic material. After the height of the sleeve is adjusted, the light shielding film is stretched. Therefore, the height of the light shielding can be adjusted by rotating the nut, so that it can be suitable for LED lamp beads of different heights, thereby improving practicality.
