Abstract: The present invention provides an LED lamp and a temperature control circuit applied to the LED lamp. The LED lamp includes at least one LED unit, a magnetic ballast, and an LED drive circuit. The magnetic ballast is coupled to a power and configured to limit and stabilize a received alternating current. The LED drive circuit includes a temperature control circuit. The temperature control circuit is coupled to the magnetic ballast and connected in parallel with the LED unit, is configured to detect an internal temperature of the LED lamp and adjust an output power of the LED unit, and includes a thermal sensitive module having a negative temperature coefficient thermistor and a phase cut circuit. The phase cut circuit is coupled to the thermal sensitive module, and adjusts the output power of the LED unit by decreasing a resistance of the negative temperature coefficient thermistor when the negative temperature coefficient thermistor detects that the internal temperature of the LED lamp is higher than a specified temperature threshold.

Abstract: The present invention discloses a light-emitting diode lamp for connecting to an external current source. The LED lamp comprises: a lighting source comprising a plurality of LEDs; a power control module for connecting in parallel to the external current source; and a driver unit connected between the power control module and the lighting source, wherein the power control module is configured to transform a source voltage of the external current source to a desired load voltage based on output power requirement of the plurality of LEDs; and the driver unit is configured to rectify the desired load voltage and output a driving voltage to drive the plurality of LEDs. Without the need to modify a lamp base of a conventional High Intensity Discharge lamp, the LED lamp of the present invention can be directly used to replace the HID lamp. Moreover, the power control module of the present invention ensures that LED lamps of different power have consistent shapes and dimensions, thus enhancing the versatility of components of the LED lamp and reducing the production costs.
