Is the projector good for laser or light?
Your question is not one or two words can reply clearly, you want to know what to buy the projector, can do really well, we must first understand the type of technology, application and classification of clear source projector, thorough here may not explain, I will have the opportunity to clear in my personal blog.
According to the projector display technology can be divided into three: CTR projector, 3LCD projector, DLP projector, LCD projector, LCOS projector, the most widely used technology and DLP and LCD.Projector according to the application environment can be divided into: family theater type, portable business type, education conference type, mainstream engineering type, professional theater type;Different application environments require different technical parameters and even shape sizes of projectors.By the use of the projector light source can be divided into: LED light source projector, UHP lamp (super light) projector, UHE projector and projector lamp metal halide lamp;UHP bulb is an ideal cold light source, but because of its high price, it is generally used in overhead projector.The UHE lamp produces a cold light, compact shape, which produces a large amount of light at the same power consumption, and has a longer life. When it fails, it immediately goes out. The utility model has the advantages that the service life is long, and the utility model can be used normally for more than 4000 hours, and the brightness attenuation is very small. The metal halogen bulb has a high heating temperature and is of high requirement for the cooling system of the projector. It should not be used for a long time (more than 4 hours) projection.
