Description

Technical Field

[0001] The utility model relates to the technical field of LED lamps, in particular to an optical lampshade of an LED lamp. Background Art

[0002] LED lamps refer to lighting equipment that uses LED as a light source. They are usually composed of LED light sources, heat sinks, drivers, and optical components.

[0003] The LED lampshade is a component of LED lamps and is usually located outside the LED light source. It has the following functions: Protection: Protects the internal LED light source from damage by dust, moisture and other external factors; Decorative: The design and material of the lampshade can beautify the appearance of the lamp and coordinate with the interior decoration style; Optical optimization: The lampshade can be designed into different shapes and materials to optimize the distribution of light, reduce glare and improve lighting effects; Safety: Some lampshade materials have an insulating effect, which can prevent electric shock and improve safety in use.

[0004] However, the size of the lampshade on the market needs to be determined according to the shape and size of the LED lamp, but the probability of the lampshade being damaged is lower than the probability of the LED lamp being damaged. Therefore, the frequency of replacing LED lamps is higher than the frequency of replacing lampshades. However, the shapes of LED lamps are different, and replacing an LED lamp with a new shape may not fit the old lampshade, resulting in the need to purchase a lampshade that is the same size as the new LED lamp, which increases the cost of replacing the LED lamp. In view of this, an optical lampshade for an LED lamp is provided to overcome the above-mentioned defects. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings of the prior art and to propose an optical lampshade for an LED lamp.

[0008] As a further description of the above technical solution: the first inner ring is arranged at an upper position of the inner wall of the outer ring, the pitch of the first internal thread is the same as the pitch of the first external thread, and the pitch of the first external thread is the same as the pitch of the second internal thread, so that the first external thread can be inserted into the first internal thread and rotated, so that the first external thread and the first internal thread are spirally connected to achieve a fixing effect.

[0009] As a further description of the above technical solution: the extension ring is arranged on the outside of the bottom of the outer ring, and the width of the extension ring matches the width of the second external thread on the upper inner side of the lampshade body, so that the second external thread can be inserted into the second internal thread and rotated, so that the second external thread and the second internal thread are spirally connected to achieve the purpose of fixing the lampshade body.

[0010] As a further description of the above technical solution: the connection between the outer ring and the first inner ring and the second inner ring is fixed by adhesive bonding, and the width of the first inner ring and the second inner ring is half of the width of the outer ring, so that the first inner ring and the second inner ring can be adhered to the inner wall of the outer ring, and several outer rings can be stacked, so that the second outer thread on the outside of the extension ring can be inserted into the first inner thread in the first inner ring.

[0011] As a further description of the above technical solution: a limiting seat is fixedly connected to the lower inner side of the second inner ring, and a convex lens is placed above the limiting seat. The edge of the convex lens contacts the inner side of the second inner ring, which can increase the brightness of the LED lamp body to a certain extent. The convex lens has the characteristic of converging light and can focus the light emitted by the LED lamp at the lampshade position, thereby improving the brightness.

[0012] As a further description of the above technical solution: the inner diameter of the limit seat is two centimeters smaller than the cross-sectional diameter of the convex lens, and the outer diameter of the limit seat matches the inner diameter of the second inner ring, and the inner diameter of the second inner ring matches the cross-sectional diameter of the convex lens, which can avoid the situation where the outer ring is set between the LED lamp body and the lampshade to increase the distance, resulting in a decrease in the brightness of the light emitted from the LED lamp body from the lampshade.

By adjusting the distance between the lampshade and the lamp panel, the scattering and distribution of light can be optimized, thereby improving the uniformity of lighting.

[0015] The optical lampshade of the LED lamp designed by the present invention can increase the brightness of the LED lamp body to a certain extent through the design cooperation of the limit seat and the convex lens. The convex lens has the characteristic of converging light and can focus the light emitted by the LED lamp at the position of the lampshade, thereby improving the brightness of the light and avoiding the situation where the outer ring set between the LED lamp body and the lampshade increases the distance, resulting in a decrease in the brightness of the light emitted from the LED lamp body from the lampshade. The convex lens can be installed selectively. If the length of the LED lamp body needs to pass through the second inner ring inside the outer ring, there is no need to install the convex lens, which provides users with multiple choices and strong versatility.

[0023] As a further implementation scheme of the above technical solution: the first inner ring 3 is arranged at an upper position of the inner wall of the outer ring 5, the pitch of the first internal thread 4 is the same as the pitch of the first external thread 2, and the pitch of the first external thread 2 is the same as the pitch of the second internal thread 10, so that the first external thread 2 can be inserted into the first internal thread 4 and rotated, so that the first external thread 2 and the first internal thread 4 are spirally connected to achieve a fixing effect.

[0024] As a further implementation plan of the above technical solution: the extension ring 7 is arranged on the outside of the bottom of the outer ring 5, and the width of the extension ring 7 matches the width of the second external thread 9 above the inner side of the lampshade body 8, so that the second external thread 9 can be inserted into the second internal thread 10 and rotated, so that the second external thread 9 and the second internal thread 10 are spirally connected to achieve the purpose of fixing the lampshade body 8.

[0025] As a further implementation plan of the above technical solution: the connection between the outer ring 5 and the first inner ring 3 and the second inner ring 6 is fixed by adhesive bonding, and the width of the first inner ring 3 and the second inner ring 6 is half of the width of the outer ring 5, so that the first inner ring 3 and the second inner ring 6 can be adhered to the inner wall of the outer ring 5, and several outer rings 5 can be stacked, so that the second external thread 9 on the outside of the extension ring 7 can be inserted into the first internal thread 4 in the first inner ring 3.

[0028] Working principle:

[0029] When using the present invention, the distance between the lampshade body 8 and the lamp panel 1 is adjusted according to the LED lamp body 11 fixed below the lamp panel 1.

Then, determine whether the length of the LED lamp body 11 exceeds the top of the outer ring 5. If not, directly put the first inner ring 3 on the upper inner side of the outer ring 5. At the position of the first external thread 2 on the outer side below the lamp panel 1, the first internal thread 4 on the inner side of the first inner ring 3 contacts and rotates with the first external thread 2, and can be tightened and fixed. If it exceeds, another set of outer rings 5 is installed on the top of the outer ring 5. The installation method is the same as the above-mentioned method of installing the outer ring 5. At the same time, when installing the outer ring 5, it can be determined whether a convex lens 13 is needed according to the brightness of the LED lamp body 11. If the brightness is low, a convex lens 13 is placed horizontally on the inner side of the second inner ring 6 below the inner side of the outer ring 5. The edge of the convex lens 13 is stuck in the position above the limit seat 12 below the inner side of the second inner ring 6. At this time, the brightness of the LED lamp body 11 irradiating the lampshade body 8 increases with the convex lens 13.
