Analysis of the United States Vivitek HD projector dismantling LED light source

Recently, LED light source 1080P HD projector Luxeon debut in Shanghai, an innovative projector products, the key to the effect of the picture function, after watching it innovation. First of all, please join the LED light source 1080P projector screen world (Figure 1, figure 2), do a great color travel. We will then show you how the LED light source works to provide a stable and reliable source for the projector.

After seeing the disassemble LED driver board protective sleeve (Figure 3), which is hidden below critical LED driver board. (Figure 4)

LED drive motherboard, three black bolts are three LED lamp data transmission line.

After removing the LED drive motherboard, the 1, 2, and 3 labels in Figure 5 are the three LED lamps and their fins. Label 4 for projector light path.

The LED cooling plate removed after 20000 hours of longevity secret is revealed to the world, from the chart we can see the projector in the heart of the chip LED luminous body, as the ultimate alternative projector lamp, the luminous body size did not even have the projector lamp 1/10, with its base size only one CPU size.

Figure 4 the structure of the LED drive board

The picture is No. 1 marked LED circuit board power supply, No. 2 marked LED signal input interface, 3 marked Light Road No. 4 is a closed rubber, marking the LED chip, and the picture of similar things like cement, is used to fix the circuit board LED silica gel.

The optical part of the picture is the first gate of the projector. When the projector is working, the LED luminous body is through the convex lens to enlarge the light beam, into the projector light path will be a large screen through the projector lens, the screen will be displayed in front of us.
