Description

Technical Field

[0001] The utility model belongs to the field of lamps, and in particular relates to a lens mechanism and a lamp. Background Art

[0002] For lamps, in order to meet their different illumination needs, they are usually used in conjunction with lens structures; when the light of the lamp passes through the lens of the lens structure, part of the light energy is absorbed by the lens and converted into heat energy and heat energy of the LED lamp bead body, causing the local temperature of the lens to rise; when the temperature of the lens is too high, the lens is likely to be thermally deformed due to the temperature increase, causing the refractive index and reflection direction of the lens to change, affecting the illumination effect of the lamp; and if a heat dissipation port is opened on the shell of the lens structure, although its heat dissipation can be effectively improved, the light of the lamp is likely to leak out from the heat dissipation port, which will undoubtedly also affect the illumination effect of the lamp. Utility Model Content

[0003] The purpose of the utility model is to provide a lens mechanism, which has a light-proof heat dissipation structure, which can ensure the heat dissipation effect and avoid light transmission.

[0004] Another object of the present invention is to provide a lamp having a light-proof heat dissipation structure at a lens mechanism thereof, which can ensure the heat dissipation effect and prevent light from being transmitted.

[0005] In order to achieve the above-mentioned purpose, the technical solution of the present utility model is as follows.

[0006] A lens mechanism, characterized by comprising:

[0007] A lens housing, wherein a lens cavity is provided within the lens housing, and two sides of the lens cavity respectively penetrate the two sides of the lens housing to form a light inlet and a lens port, respectively. A heat dissipation inlet is provided on the side of the lens cavity, and a heat dissipation outlet is provided on the outside of the lens housing, which is offset from the heat dissipation inlet. A heat dissipation connection channel for preventing light leakage is also provided within the lens housing, and the heat dissipation inlet and the heat dissipation outlet are both connected to the heat dissipation connection channel.

[0008] The lens is fixedly arranged on the lens port.

[0009] In this lens mechanism, after the airflow passes through the heat dissipation inlet, it passes through the heat dissipation connection channel and is discharged from the heat dissipation outlet to dissipate heat; based on the staggered setting of the heat dissipation outlet and the heat dissipation inlet, the light emitted from the light inlet of the external lamp structure will not leak through the heat dissipation outlet, so that the lens mechanism can both ensure its heat dissipation effect and avoid light transmission.

[0010] Furthermore, the heat dissipation outlet is arranged on a side of the lens housing close to the lens port.

[0011] Furthermore, there are multiple heat dissipation outlets, and the multiple heat dissipation outlets are arranged around the outside of the lens port.

[0012] Furthermore, there are multiple heat dissipation inlets, and the multiple heat dissipation inlets are arranged around the side surface of the lens cavity.

[0013] Furthermore, the lens housing includes a first body and a second body, the lens cavity is arranged in the first body, and the light inlet and the lens port are respectively located on both sides of the first body; a socket hole is provided in the second body and passes through both sides of the second body, and a fixing ring is fixed on one side of the second body and surrounds one side of the socket hole. The second body is sleeved on the outside of the first body through the socket hole, the lens is arranged between the fixing ring and the lens port, the heat dissipation outlet is arranged on the fixing ring, and the heat dissipation connection path is shaped between the first body and the second body.

[0014] Furthermore, a mounting ring is provided on one side of the fixing ring near the sleeve hole, and a mounting position for positioning and installing the lens is formed between the mounting ring and the fixing ring. After the lens is placed in the mounting position, the second body is sleeved onto the outside of the first body through the sleeve hole, so that the lens opening side of the first body abuts against the lens to fix the position of the lens. The provision of the mounting position makes installation of the lens mechanism more convenient.

[0015] Furthermore, the mounting ring is provided with an escape opening at a position corresponding to the heat dissipation inlet. The setting of the escape opening allows airflow to enter the heat dissipation inlet more efficiently.

[0016] A lamp, characterized in that it includes the lens mechanism and a lamp mechanism for emitting light, the lamp mechanism being disposed on the lens housing and corresponding to the light inlet. In the lamp, airflow passes through the heat dissipation inlet and then through the heat dissipation connection channel to be discharged from the heat dissipation outlet for heat dissipation. Due to the staggered arrangement of the heat dissipation outlet and the heat dissipation inlet, light emitted from the light inlet by the lamp mechanism does not leak through the heat dissipation outlet, thereby ensuring that the lens mechanism can both ensure heat dissipation and prevent light transmission.

[0017] Furthermore, the lamp mechanism includes a lamp housing, a light assembly, and a fan assembly. The light assembly and the fan assembly are both arranged in the lamp housing. The light housing is connected to the lens housing. The light assembly extends into the light inlet, and a ventilation gap is formed between the light assembly and the light inlet. The fan assembly corresponds to the ventilation gap.

[0018] Furthermore, a heat dissipation fin may be provided on a side of the lamp facing away from the light inlet, the heat dissipation fin being located between the fan assembly and the ventilation gap, and an air inlet is provided on the outer side of the lamp housing corresponding to the fan assembly.

[0019] In the present invention, after the airflow passes through the heat dissipation inlet, it passes through the heat dissipation connection channel and is discharged from the heat dissipation outlet to dissipate heat; based on the staggered setting of the heat dissipation outlet and the heat dissipation inlet, the light emitted from the light inlet of the external lamp structure will not leak through the heat dissipation outlet, so that the lens mechanism can both ensure its heat dissipation effect and avoid light transmission.
