Description

Technical Field

[0001] The utility model relates to the technical field of lamps, in particular to a double-layer light-transmitting bulb. Background Art

[0002] Lighting is the use of various light sources to illuminate work and living places or individual objects. Light bulbs can be understood as a device that realizes the lighting function; as a new energy source, light bulbs have been widely used in the field of lighting due to their advantages such as good energy saving effect and long life.

[0003] In the existing light bulb, when it is in use, the light bulb is directly exposed to the outside world, so as to illuminate the outside world and facilitate use; however, due to the long-term exposure of the light bulb to the outside world, dust and dirt may easily accumulate, which not only affects the light effect of the light bulb, but also may reduce the service life of the light bulb; at the same time, the glass shell of the light bulb is relatively fragile and is easily broken by impact or compression, which makes it inconvenient to use. In view of this, we introduce a double-layer light-transmitting light bulb. Utility Model Content

[0004] The purpose of the utility model is to provide a double-layer light-transmitting bulb to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a double-layer light-transmitting bulb, comprising: an outer cover and a mounting cavity;

[0006] The inner side of the outer cover is provided with an external thread A, the surface of the external thread A is meshed with an internal thread A, and the outer side of the internal thread A is provided with an inner cover;

[0007] The installation cavity is opened on the surface of the outer cover, a lamp holder is arranged inside the installation cavity, and a controller is connected to the top of the lamp holder;

[0008] A mounting mechanism is provided between the mounting cavity and the lamp holder, and the lamp holder is mounted inside the outer cover by meshing the external thread B of the mounting mechanism with the internal thread B.

[0009] Preferably, the mounting mechanism includes a light source arranged at the bottom of the lamp holder, the internal thread B is connected to the inner side of the outer cover, the external thread B is connected to the outer side of the lamp holder, and the internal thread B is meshed with the external thread B.

[0010] Preferably, a positioning plate is connected to the surface of the lamp holder.

[0011] Preferably, a fixing cavity for mounting the light source is provided inside the inner cover.

[0012] Preferably, the light bulb includes a lamp holder that can be fixedly connected or a lamp holder that can not be fixedly connected.

[0013] Preferably, the light source can be a soft light strip, a hard light strip, a patch, or a copper wire light string.

[0014] Preferably, the material of the outer cover and the inner cover is not limited to glass, but can also be plastic, metal, wood, bamboo, stone.

[0015] Preferably, the fixing connection between the inner cover and the outer cover is not limited to threaded fixing, but can also be fixed by snapping or gluing.

[0016] Compared with the prior art, the beneficial effect of the utility model is as follows: the utility model matches and screws the external thread B on the outside of the lamp holder with the internal thread B on the inside of the outer cover. When the lamp holder is continuously rotated, the lamp holder will move toward the inside of the installation cavity, and the positioning plate on the surface of the lamp holder will contact the top of the outer cover, thereby limiting the lamp holder and forming an installation fixation. Then the inner cover is installed in the outer cover, and the internal thread A on the inside of the inner cover is matched and screwed with the external thread A on the outside of the outer cover. When the inner cover is continuously rotated, the inner cover can be installed inside the outer cover, making the installation more convenient. The light source at the bottom of the lamp holder will enter the inner cover, thereby preventing external dust from falling on the surface of the light source, thereby protecting the light source and increasing its service life.
