Title: Lighting device
Inventor: OUCHIDA YASUSHI
IPC: F21V29/505
Filed: 1991-02-19
Abstract: PURPOSE:To radiate the heat from a lamp efficiently and to suppress a rise in the temperature of the lighting device by composing a reflecting member of a metallic plate which has a reflection part and a heat radiation part. CONSTITUTION:The reflecting member which reflects the light from the fluorescent lamp 2 and makes it incident on a photoconductor 1 is composed of the metallic plate which consists of the reflection part 5 and heat radiation part. The size of the metallic plate 3 which covers the surface of a reflecting layer is not important and only properly selected according to the material of the metallic plate 3. Further, holes for improving the heat radiation effect may be bored in the metallic plate 3 except at the reflection part 5. Thus, the metallic plate 3 is used as the reflecting member of the lighting device to accelerate the heat radiation from the fluorescent lamp 2. The temperature rise of the lighting device is therefore suppressed and when this device is used as the back light source of a liquid crystal display device, etc., the display deterioration of the liquid crystal device due to heat generated by lighting is prevented.

Filed: 1987-02-07
Abstract: PURPOSE:To realize an access to a block with a small hardware quantity before the block is transferred by counting the data transfer frequencies of a block transfer to judge the possibility of an access for processing in case it is detected that a subsequent read request gives an access to the block under transfer. CONSTITUTION:When a read request is received, a comparator 11 decides whether an address 3 obtained with the read request is equal to the address of the same block or not. While a hit deciding circuit 16 decides the difference between the address of the read request and an address held by a register 4. At the same time, a restart control circuit 17 counts the data transfer frequencies during the transfer of a single block. A request control circuit 7 decides whether the data to receive an access by a read request is already written into a data array 2 or not from the outputs of a hit deciding circuit 16 and the circuit 17. If said data is already written, the read request is processed. While the processing of the read request is held if the data is not written yet.
