1. Wang, Hui-chi. SMD Type Metallic Reflection Cup LED Component on the Application of Backlight Module.

Degree: Master, Mechanical and Electro-Mechanical Engineering, 2009, NSYSU

Nowadays, using the LED as backlight module's light source becomes generalization gradually, and the application of LED light source develops from the liquid crystal display to the liquid crystal TV. However, thermal dissipative problem of LED component is still an important issue to study presently, since it can affect the service lives of LED and LCD seriously. In order to increase the luminous energy of the LED component, one need to increase the supply of electric power and it will cause the increment of thermal dissipative problem of the LED component also. Therefore, by considering the LED components as the light source of the backlight module , the purpose of this study is to reduce number of the required LED components in order to decrease the thermal dissipative problem of LEDs, and maintain the luminous and uniformity of the backlight module simultaneously. A new packaging for LED, named SMD type metallic reflection cup LED component, was proposed in this study. The new LED package not only has a better thermal dissipative property, but also can control its radiation property by changing the angle of its reflection cup. So, the proposed LED package can be applied for different purposes. By applying the proposed LED components as the light source of a backlight module, under the condition of same illumination, it can be shown that the required number of LED components can be decreased tremendously and so the thermal dissipative problem can be decreased too. Also, the numerical simulated results showed that by choosing the suitable angle of the reflection cup, the uniformity of the backlight module can be improved. Besides, this study proposed a modified method for assessing the uniformity of a backlight module. The simulated results showed that the proposed method can assess the uniformity of a backlight module more suitable than the traditional nine points measurement method can do.
