Description

Technical Field

[0001] This utility model relates to a projector, specifically a spherical projector. Background Technology

[0002] A projector, also known as a projector, is a device that projects images, text, and other information onto a screen using optical projection technology. Projectors are widely used in homes, conference rooms, classrooms, and other settings for watching movies, presenting PowerPoint presentations, and conducting teaching.

[0003] In the past, projectors typically used rectangular or cylindrical casings, making them bulky and inconvenient to carry. Furthermore, traditional projectors had limitations in heat dissipation, which could easily lead to overheating of the light source components, affecting their stable operation and lifespan.

[0026] like Figure 1 and Figure 2 As shown, a spherical projector of this utility model includes:

[0027] The outer shell 1 has a spherical structure. A lens module 3 is fixedly installed at one upper end of the outer shell 1, and a reflector 4 is installed inside the outer shell 1.

[0028] The light source assembly is housed within the housing 1, with the reflector 4 and lens assembly positioned at a 37.5° angle, resulting in a more compact internal layout. The light-emitting end of the light source assembly illuminates the reflective surface of the reflector 4 and refracts the light onto the lens module 3, thereby saving internal space.

[0029] Mainboard 2 is located inside the outer casing 1 and is connected to control the operation of the LED light source.

[0030] In order to achieve the effect of heat dissipation, in this embodiment, a heat sink 5 is connected to one side of the light source component, and a fan 6 is provided at the front end of the heat sink 5 to cool the heat sink.

[0031] In addition, the light source assembly includes an LED light source 7, a reflector 8, a rear Fresnel lens 9, an LCD screen 10, and a front Fresnel lens 11.

[0033] To facilitate air intake and exhaust, one end of the housing 1 is provided with an air outlet 13 corresponding to the fan 6, and the fan 6 is aligned with the air outlet 13 through its exhaust end; the other end of the housing 1 is provided with an air inlet 14, which is aligned with the position of the light source component. The fan 6 draws air in through the air inlet 14, which passes through the light source component and the heat sink 5 in sequence, and is then blown out through the air outlet 13, thereby achieving the effect of heat dissipation.

[0034] The heat sink 5 is composed of heat dissipation fins and copper pipes. The copper pipes are bent and arranged, and the heat dissipation fins are installed at one end of the copper pipes. The other end of the copper pipes is in contact with the LED light source 7.

[0035] In addition, a fixing hole 15 is provided at one upper end of the housing 1, and the lens module 3 is fixed in the fixing hole 15 to facilitate the installation of the lens.

[0036] This utility model adopts a spherical shell, which has good protective performance and can effectively protect the internal components; the 37.5° setting of the light source component and the reflector 4 makes the internal layout more reasonable; the setting of heat sink and fan ensures the heat dissipation requirements of the light source component during operation and extends the service life of the equipment; the setting of air outlet and air inlet achieves good airflow circulation and ensures heat dissipation inside the equipment.
