Abstract: A vehicular LED lamp includes a mounting seat and a plurality of LED light-emitting units mounted on the mounting seat. Each LED light-emitting unit includes a carrier plate having inner and outer surfaces, a circuit board engaged on the outer surface of the carrier plate, and at least one LED mounted on the circuit board and in contact with the outer surface of the carrier plate. The mounting seat includes a plurality of mounting grooves each having a bottom wall and two side walls with inclined sections. The LED light-emitting units are received in the mounting grooves of the mounting seat, with the inner surface of each carrier plate in contact with the bottom wall of an associated mounting groove, with two sides of each carrier plate abutting the inclined sections of the associated mounting groove.

Abstract: A vehicular LED lamp monitoring/controlling system includes a vehicular LED lamp having first and second LEDs. A selection/control unit is connected to and controls separate activation of the first and second LEDs and is connected to a malfunction detecting unit that detects operation of the first and second LEDs. The second LED is activated when the first LED operates abnormally. A power control unit can send a control signal to the selection/control unit to control luminance of each of the first and second LEDs. A vehicle speed monitoring unit connected to the power control unit reads a speed of a vehicle on which the vehicular LED lamp is mounted. When the vehicle is moving, the first or second LED provides normal luminance. When the vehicle is not moving, the first or second LED provides reduced luminance.

Abstract: A system includes first and second illuminating devices respectively having different first and second identification numbers indicative of locations and/or serial numbers of the illuminating devices. A parameter of one of voltage, temperature, resistance, and power of a lighting unit of each illuminating device is detected. The parameter and the identification number of each illuminating device are encoded into a packet. The second illuminating device receives the packet of the first illuminating device and sends the packets of the first and second illuminating devices to a control center. The control center decodes the packets and judges operational states of the illuminating devices based on the parameters detected. A control signal is sent by the control center to turn on or off or control brightness of at least one of the illuminating devices when at least one of the illuminated devices is judged as operating abnormally after judging the parameters detected.

Abstract: A lamp (6) includes a housing (5) mounted to a lamp post (4) and a light-emitting diode module (10) mounted in the housing (5). The light-emitting diode module (10) includes a metal substrate (21) and a plurality of light-emitting diode dies (221) mounted on a face (211) of the metal substrate (21). A jacket (11) has a coupling surface (112) engaged with the other face (212) of the metal substrate (21). A heat conduction pipe (12) includes a portion (123) received in a longitudinal hole (111) of the jacket (11). The coupling surface (112) of the jacket (11) has an opening (114) in communication with the longitudinal hole (111). A portion of an outer periphery (124) of the portion (123) of the heat conduction pipe (12) is in direct, thermal contact with the other face (212) of the metal substrate (21) through the opening (114) of the jacket (11) to absorb heat generated by the light-emitting diode dies (221).

Abstract: A light-emitting diode module with a heat dissipating structure includes a metal substrate and a plurality of light-emitting diode dies mounted on a face of the metal substrate.

A finned heat sink is mounted on another portion of the heat conduction pipe outside the jacket to dissipate heat transferred to the heat conduction pipe into the environment.
