Light emitting diode module having a latching component and a heat-dissipating device

A LED module having a LED connected to a power source, the LED module comprising:

• a heat-transfer member having a heat-dissipating unit remote from the LED and a heat-transferring unit thermally connecting the LED and the heat-dissipating unit for dissipating heat from the LED through the heat-dissipating unit;
• a heat spreader coupled to the heat-transferring unit of the heat-transfer member and spreading the heat from the LED;
• a circuit board positioned on the heat spreader, wherein the circuit board holds the LED thereon and is electrically connected to the LED;
• and
• a latching component covering and secured to the heat spreader, the latching component comprising a top surface at an end thereof and a plurality of hooked portions at another end thereof exerting a spring force on the heat spreader;
• wherein the heat spreader is located in the latching component and engages with the latching component to tightly attached to the heat spreader by when the hooked portions engaging with the heat spreader;
• wherein the latching component comprises a plurality of spring pieces and the spring pieces press the circuit board being attached to the heat spreader, the spring pieces electrically connecting with the circuit board and the LED;
• and
• wherein each spring piece comprises a strip-shaved body and a pair of fixed claws extending from two opposite end portions of the strip-shaped body.

A LED module comprising:

• a printed circuit board having a LED mounted on a first surface thereof;
• a heat spreader abutting against a second surface of the printed circuit board opposite the first surface thereof;
• a heat pipe having an evaporating section extending through the heat spreader to thermally connect with the second surface of the printed circuit board and the LED, the evaporating section of the heat pipe being perpendicular to and engaging with the second surface of the printed circuit board;
• and
• a latching member enclosing the printed circuit board and the heat spreader therein, engaging with the heat spreader and having a spring member exerting a pushing force on the printed circuit board toward the heat spreader and the evaporating section of the heat pipe, the spring member electrically connecting wit the printed circuit board and the LED.
