The present disclosure relates to various embodiments to enable the assembly, construction, and operation of a miniature integrated LED lamp comprising an envelope positioned at a distal end of a solid body portion and a base positioned at a proximal end of the solid body. The envelope further comprises a transparent light diffuser enclosing a semi-cylindrical light pipe containing one or more LEDs populated on its external surface and a LED driver positioned internally within a formed lumen of the light pipe. The light pipe and LED driver are physically and or electrically connected to a cylindrical heatsink encapsulated within the envelope and body portion of the bulb, facilitating thermal management. The envelope and base are assembled together with one or more specific lamp bases to form an LED lamp satisfying performance standards suitable for retrofit or replacement of a standard INC or halogen lamp.

The present disclosure proposes an LED lamp with omnidirectional heat dissipation, which includes an LED lamp housing including a power supply component inside, and a heat sink supporting an LED chip. The LED lamp housing and the heat sink are separated by a heat insulation member to block thermal influence between each other. The LED lamp of the present disclosure adds a heat insulation plate between the LED lamp housing for placing the power supply component and the heat sink, to block and weaken the mutual influence between the heat generated by the LED chip and the heat generated by the power supply component. The design improves the problem of excessively high ambient temperature inside the power supply cavity of the traditional LED lamps, effectively avoids damage to the power supply device due to long-term working in a high-temperature environment, and improves the service life of the LED lamp.

An electromagnetic illuminator heater is provided having a heat generating wire and an elongate encasement of thermally transmissive, temperature mitigating, and electrically insulative material. The material encompasses the elongate heating wire. A heater for devices is also provided.
