Disclosed herein are systems and methods for melting cold weather related obstructions (snow, ice, frost, etc.) off of vehicle lamps by heating the lens of the housing, thus restoring the normal operating abilities (e.g., brake light illumination, running light illumination, turn signal illumination). This can allow for an efficient signaling process (e.g., to the following vehicle), thus raising the general level of safety on the roads.

A light emitting and receiving module with heater is provided, which includes a base material. A light emitting and receiving element is disposed on the base material and performs at least one of light reception and light emission. A heater film includes an electrode formed on a base sheet. The heater film is formed so as to cover the light emitting and receiving element. A capacitance detection unit electrically connected to the electrode detects a floating capacitance between the light emitting and receiving element and the heater film. A power source electrically connected to the electrode heats the heater film. A control board switches the connection with the electrode between the capacitance detection unit and the power source.

A hybrid light and fan fixture includes a plurality of LED lights surrounding a fan and its motor within a housing. A connector is made to allow the hybrid fixture to be installed in a conventional light socket for 110v electrical power. An alternative embodiment includes either or both features of a set or rotatable deflector blades and a serpentine heating element to more positively influence the air flow created by the fan and make the air stream more effective in de-fogging the mirror. Preferably, the fixture includes a circuit that allows the lights to be energized with and without the fan and heating element.

An optical wavelength converter (1) is configured such that an optical wavelength conversion member (9) is bonded to a heat dissipation member (13) having superior heat dissipation property. Thus, heat generated by light incident on the optical wavelength conversion member (9) can be efficiently dissipated. Therefore, even when high-energy light is incident on the optical wavelength converter, temperature quenching is less likely to occur, and thus high fluorescence intensity can be maintained. An intermediate film (21) is disposed between a reflective film (19) and a bonding portion (15). The presence of the intermediate film (21) improves the adhesion between the reflective film (19) and the bonding portion (15), thereby enhancing the heat dissipation from the optical wavelength conversion member (9) to the heat dissipation member (13). Thus, the temperature quenching of the optical wavelength conversion member (9) can be prevented, thereby enhancing fluorescence intensity.
