Abstract

The embodiment of the invention belongs to the technical field of projectors, and relates to a desktop projector which comprises a body. The body comprises a shell, a first fan, a radiator, a light flux, a light-emitting lamp strip plate, a first Fresnel lens, a display screen, a second Fresnel lens, a reflector and a lens. The first fan is arranged close to the shell, a light source of the desktop projector is arranged on the radiator, the radiator is provided with a heat dissipation base, and one end of the heat dissipation base is tightly attached to the first heat dissipation fan. The light flux, the first Fresnel lens, the display screen and the second Fresnel lens are sequentially arranged in parallel, and the light-emitting lamp strip plate is arranged between the light flux and the first Fresnel lens, wherein the light flux is arranged on the heat dissipation base; the reflector is arranged at one side, deviating from the display screen, of the second Fresnel lens, an included angle is formed between the reflector and the second Fresnel lens, and the included angle is larger than 30 degrees and smaller than 60 degrees; the lens is arranged in the included angle range of the second Fresnel lens and the reflector and is used for projecting an image of the display screen to a desktop or the display screen located on the desktop.

Description

technical field [0001] The present application relates to the technical field of projectors, in particular to a desktop projector. Background technique [0002] With the improvement of people's living standards and cultural quality and the needs of work and study, electronic terminals such as computers, tablets, and mobile phones have been popularized in many places and families, and have become necessary tools for people to study and work. Touching the display cannot be avoided when using the above equipment. When people study or work facing the monitor for a long time, the radiation from the monitor directly affects people's health, and the most direct result is myopia. However, if the display is separated, the convenience brought by the above-mentioned electronic terminal cannot be used. In order to solve the above problems, there is an urgent need for a radiation-free or low-radiation terminal display method. Contents of the invention [0003] The purpose of the emb...
