The seat member defines slim grooves aligned with the lens and the fiber cables are received and retained in the slim grooves.
摘要:
A driving circuit of a light emitting diode (LED) is provided, including a driving unit, a current pre-charging unit and a feedback selecting unit. The driving unit outputs a driving power to drive the LEDs and outputs at least a first feedback signal according to the current conducted by the LEDs. The current pre-charging unit is coupled to an output of the driving unit to provide a current path to the driving unit and generates a second feedback signal according to a current conducted by the current pre-charging unit. The feedback selecting unit selects and outputs one of first feedback signals or the second feedback signal according to an enable signal, and the driving unit adjusts the driving power according to an output of the feedback selecting unit so as to maintain a current driving capability of the driving circuit to provide a sufficient current to drive the LEDs.
摘要:
An electrical connector comprises a base having a plurality of passageways for receiving a number of contacts, a cover mounted to the base and including a plurality of through holes corresponding to the passageways, and a lid having two opposite edges. One edge is mounted upon the cover to drive the cover to move relative to the base, and the other edge locks the base when the lid is located at a close position relative to the base.

An electrical contact (1) includes an upper extending portion (11), a lower extending portion (12) and a bridge portion (13). The upper extending portion includes a first contact portion (111), a C-shaped connecting portion (1121) connecting with the first contact portion and a tail portion (1122) extending downwardly from a free end of the C-shaped connecting portion. The lower extending portion includes a second contact portion (121), a vertical portion (1222) and an inclined portion (1221) connecting with the second contact portion and the vertical portion. The bridge portion is integrally formed between the tail portion and the vertical portion. One of the upper extending portion and the lower extending portion is rotated around the bridge portion to form an angular relationship between the planes of the upper and lower portions.
