Furthermore, an installation part for installation and fixation is formed at the periphery of the light-emitting mirror, and the electrode plate is located at the installation part. Because the mounting seat for mounting the light-emitting mirror is generally lighttight, namely, the light of the light source can not be emitted from the mounting part, the electrode plate is arranged on the mounting part, and the light beam can be effectively prevented from being shielded.
Further, the transparent heating circuit is sheet-shaped and is matched with the shape of the light-emitting mirror. The transparent heating circuit is a large film, covers the whole light-emitting mirror, is directly and integrally arranged on the surface of the light-emitting mirror, and is convenient and quick.
Furthermore, the transparent heating circuit is strip-shaped, and is distributed in a zigzag manner, spirally distributed or formed into a plurality of concentric rings on the surface of the light-emitting mirror. The material usage of the transparent heating circuit is reduced, the cost is reduced, the interception area of the light beam can be reduced, and the influence on the light beam is reduced.
Further, the area covered by the transparent heating circuit is larger than one half of the area of the light-emitting mirror. And ensuring an enough heating range to enable the light-emitting mirror to be heated quickly.
Furthermore, the light-emitting mirror and the inner side wall of the lamp cap are sealed, so that the cavity is sealed. Namely, the lamp cap has waterproof capability, and at the moment, the inner side of the light-emitting mirror is easier to adsorb water vapor, oil mist or dust, and the light-emitting mirror needs to be heated.
Furthermore, the transparent heating circuit is located at one side of the light-emitting mirror close to the light source. Facilitating the supply of power to the transparent heating circuit.
