Which is better, a projector or a slide projector for teaching?

Projectors and slide projectors,Fundamentally different usesProjectors can watch movies through the computer,But the slide projector can't watch movies,Can only be used in the ****。 In fact, many of them are all-in-one machines!! Equipped with both of these functions!!

The lamps of the slide projector are not expensive, and the projector lamps are good at 1500 to be sure, but the functions of the projector are relatively more comprehensive.

It is still recommended to have a projector,The teacher can choose to buy NWC,BenQ,Rili these machines,No matter what** or the quality is still very good,I don't want to be a big brand in the first line can't accept it,If you use more **** for teaching, you can choose a DLP machine,2500 lumens**That is, about 4000 fast money,There are many brands to choose from。

Slide projector?? Projector??

It is recommended that you use the audio-visual equipment of the booth + projector Now most primary and secondary schools are equipped with such audio-visual education.

The booth is responsible for the image processing of the objects to be displayed.

The projector is responsible for displaying the picture of the object.

And the projector can also be connected to your own portable laptop.

Show your students something like an electronic document or a movie.

The booth is generally about 2,000 yuan.

There are many domestic ones, such as Hite, Founder, and so on.

Buy a projector for about 4,000 pieces, about 3,000 lumens.

Look at BenQ's **Cheap, the quality is OK, the bulb is not expensive, and you can spend a few hundred dollars to buy a set of stereos with an extra budget.

The cheap and affordable type should be about 8000 a set, you can see for yourself.

1. The structure is different.

The slide projector shines the slide to be displayed directly onto the screen by the light source through the optical device;

The projector shoots the horizontally placed projection film from the light source to the plane mirror through the optical device, and then reflects it to the screen by the plane mirror. There are two kinds of light sources: tungsten bromide lamp and dysprosium lamp.

2. Different ways to use:

According to the optical path structure, the slide projector is divided into direct type (used to show transparent slides) and reflective type (used to show opaque books, periodicals, etc.). Duan Tan.

3. Different modes of operation:

According to the operation mode, the slide projector is divided into manual type, automatic type, remote control type and sound and picture synchronization type. According to the lens, it is divided into single-lens type and multi-lens type.

There are different types of projectors according to different working methods, such as CRT, LCD, DLP, etc.

When many people use a projector, it is easy to confuse it with a slide projector, but the two are not the same. What are the differences between projectors and slide projectors? PChouse will take you to find out.

1. The difference between the elevation structure and the slide projector will be displayed by the light source directly onto the screen through the optical device; The projector shoots the horizontally placed projection film from the light source to the plane mirror through the optical device, and then reflects it to the screen by the plane mirror. There are two kinds of light sources: tungsten bromide lamp and dysprosium lamp.

2. Different ways of use: the slide projector is divided into manual, automatic, remote control and sound and picture synchronization according to the operation mode, and is divided into single-lens and multi-lens according to the lens. The projector can be directly connected to other equipment such as computers or use its own resources to carry it.

3. The difference between the concentrating system is that most of the projectors are threaded lenses, while the phantom old lamp requires that the aperture of the condenser is slightly larger than the effective picture of the slide, and the light source is at the focus of the condenser.

1.You don't have to think about high resolution, you just need 800 x 600 resolution.

2.See if your light can be controlled (mainly the light directly above the curtain), in your classroom, you can use a machine of about 2100 lumens (the higher the lumen, the higher the cost, 2100, you can, note: if the lumens here are real lumens, some manufacturers now have the parameters higher in order to make money).

3.If you are teaching, you have to consider his warranty (now the projector is divided into 2 technologies, one is the LCD projector, and the DLP projector, they are now more mature technology, I recommend that you purchase the DLP projector, because the LCD warranty is only up to 2 years, and some are even 1 year, and the DLP projector can be guaranteed to 3 years).

4.There is also the quality of the lamp of the projector (some bulbs say that it can reach 4000 hours, and the warranty is 6 months before it is used for 1 year. I use it for 4 hours a day, and you can tell me how it takes more than 2 years to use it like this).

My friend uses Optoma's projector, he has used it for a long time, he has to watch the projector movie every night to sleep, and it has been used for more than a year and a half, and the picture has not deteriorated.

You can go and see Optoma's EP716P, his price is about 8000, you may have to hoist the curtain at that time, I will help you calculate 10,000 can be (tax included).

Hitachi or Hitevision are good, it is best to choose a laser with a life that is 2-3 times longer than the ordinary.

Kiss is happy to answer for you: Can the projector be used as a slide projector? A:

Kiss projector Huiyinyan can't be used as a slide projector, oh, the difference between a slide projector and a projector? The difference between a slide projector and a projection camera 1The structure is different, the slide projector will display the slide, by the light source through the optical device directly onto the screen; The projector shoots the horizontally placed projection film from the light source to the plane mirror through the optical device, and then reflects it to the screen by the plane mirror.

2.There are different methods of use: the slide projector is divided into direct and reflective type, which needs to be used using slides or books, and the projector can be directly connected to other equipment such as a computer or use its own resources.

3.The difference between the concentrating system is that most projectors are threaded lenses, while the slide projector requires that the aperture of the condenser is slightly larger than the effective picture of the slide, and the light source is at the focus of the condenser.
