A heater system for an LED light assembly having a lens includes a flexible composite positioned around an outer surface of the lens. The flexible composite includes a polymer base layer, a plurality of conductive buses provided on the base layer, and a resistive layer electrically connecting the plurality of buses to form a circuit. The resistive layer includes conductor particles dispersed in a polymer matrix. The resistive layer has a crystalline first condition prior to applying electricity to one of the buses and an amorphous second condition in response to applying electricity to one of the buses.

The disclosure discloses an apparatus for detecting an electromagnetic touch. The apparatus includes: a driving subcircuit configured to control organic light-emitting diodes arranged in an array in an organic light-emitting diode display panel to be lightened row by row; a detecting subcircuit configured to obtain detection current flowing through the lightened organic light-emitting diodes in real time, where the detection current of each of the lightened organic light-emitting diodes comprises inductive current of the organic light-emitting diode, and driving current of the organic light-emitting diode being lightened, and the inductive current is current, generated by the organic light-emitting diode, related to a magnetic induction intensity of a magnetic field emitted by a magnetic field emitting apparatus only when the organic light-emitting diode senses the magnetic field; and a first processing subcircuit configured to determine a position of an electromagnetic touch according to the driving current of each of the organic light-emitting diodes, and the obtained detection current thereof.

A vehicle lamp includes a housing including a compartment having an opening. A reflective unit and a lighting unit are mounted in the compartment. The lighting unit includes a first circuit board and a first LED. A lens is mounted to a front end of the housing and covers the opening of the compartment. The reflective unit reflects light rays from the first LED to transmit through the lens. A heating unit includes a substrate made of a light transmittable material and a heating layer disposed on the substrate. A sensor is mounted in the compartment for detecting temperature. When the detected temperature is lower than a first predetermined temperature, the heating layer is activated to proceed with an electrical heating operation. When the detected temperature is higher than a second predetermined temperature, the electrical heating operation of the heating layer is stopped or gradually reduced.

A candle shade is adapted to fit securely atop a candle vessel. The shade assumes the form of a double conical frustum. An interior shell makes direct contact with the candle vessel. The interior shell reflects radiative heat back to the candle surface while allowing smoke and gases to vent upward. Ideally, it is constructed from aluminum sheet metal and includes a band near the lower opening for an airtight seal. An exterior shell encloses the interior shell. The exterior shell protects the outer environment from the heat of the flame, especially so that the shade can be handled safely. Insulation is aided by handles on the exterior shell. Spacers affixed to the interior shell also create an insulating air space between the interior and exterior shells. The double-cone candle shade reduces candle “set” time by 65%.
