Application Analysis of LED solid-state light source technology in home projector1

In recent years, the home projector market has grown day by day, and more and more users are focusing on projectors instead of just watching TV sets in the past, which is mainly due to major breakthroughs in some key technologies of projectors. Solid-state light source technology is one of them. The solid-state light source technology adopted by Shanshui projector is a new Advanced Light Source technology. Solid-state light source is a brand-new lighting technology, which refers to LED light source and laser light source using semiconductor light emitting technology. It has the characteristics of energy saving, environmental protection, maintenance-free, easy control, etc. the big feature is that it has a long life. Before the solid-state light source was developed and adopted, the light source used by the projector was a traditional bulb, which was a consumable material with a short service life. generally, the life span of a traditional bulb is only about 3000 hours. Based on the usage rate of the projector for 3 hours per day, it needs to be replaced in less than a year, and considering the high price of the traditional bulb, the cost of later use is high. The solid-state light source belongs to a cold light source, is encapsulated with epoxy resin, has no loose part in the lamp body, does not have the disadvantages of filament luminescence, easy burning, thermal deposition, light decay, etc. , and has extremely high luminous efficiency. the theoretical value is more than ten times that of Mercury Lamp, which can support the use of 10 thousand hours or even longer. It has almost the same long life as flat-panel TV, does not need to be replaced, and has extremely low use cost. The projector adopts LED solid-state light source technology, which has high luminous efficiency, low energy consumption, low heat generation, environmental protection, energy saving, safety and reliability, and is an ideal choice for household appliances. The service life is as long as 30 thousand hours, which is ten times the life of the traditional bulb, greatly reducing the maintenance cost of the projector and avoiding the pain of changing lights frequently.
