| Zusammenfassung: | A direct type backlight device comprise a light base and a reflection film. The light base comprise a circuit board. The circuit board has a plurality of reflective cup structure and a plurality of light unit. Each of the reflective cup structure has a reflection cavity. Each of the light unit is arranged on the circuit board and each of the light unit is located in the reflection cavity. Some light emitted from the light unit will pass through the reflection film directly. Some light emitted from the light unit is reflected to the reflection film by the reflection cavity. Some light emitted from the light unit is reflected to the reflection cavity by reflection film. The invention can achieve good radiating performance then the known technology. |
