To provide a vehicle lamp which is capable of a kind of color change.SOLUTION: A vehicle lamp capable of changing color comprises a lamp base, an LED light source plate, a color changing film, and an external lamp cover. The color change film structure is provided between the LED light source plate and the external lamp cover. The color changing film has upper and lower protective layers made of glass or plastic, and sequentially covers upper and lower transparent conductive layer, an electrochromic material layer, an ion storage layer and an electrolyte layer. By electrifying and blocking a power source to the upper and lower transparent conductive layers, the electrochromic material layer, the ion storage layer and the electrolyte layer are strongly controlled, and a color change such as transparence, a dull surface, black color, and metallic paint color occurs. This causes light to pass through a lower LED light source plate to project a light source of a different color.SELECTED DRAWING: Figure 2
【課題】一種の変色が可能な車両ランプを提供する。【解決手段】ランプベースと、LED光源板と、変色フィルムと、外部ランプカバーとを備えた変色が可能な車両ランプを提供する。LED光源板と外部ランプカバーとの間に変色フィルム構造が設けられている。変色フィルムは、上、下のガラスまたはプラスチックの保護層であり、上、下の透明な導電層、エレクトロクロミック材料層、イオン貯蔵層および電解質層を順次に覆っている。上、下の透明な導電層に通電および電源遮断することにより、エレクトロクロミック材料層、イオン貯蔵層および電解質層が強く制御され、透明、つや消し面、黒色、メタリック塗料色などの変色が生じる。これにより、下側のLED光源板を通過させ、異なる色の光源を投射する。【選択図】図2
