Abstract: A light emitting module and a car lamp are provided. The light emitting module includes a flexible light emitting panel (10) and a support (20) disposed at the shadow side of the flexible light emitting panel (10). The surface of the side of the support (20) close to the flexible light emitting panel (10) includes a plurality of sub-surfaces (201), and the plurality of sub-surfaces (201) are sequentially connected to form an integral step-shaped structure.

Abstract: The present disclosure provides a preparation method of arsenic iron alloy, which includes the following steps: ball milling arsenic powder and iron powder under the protection of inert atmosphere according to a molar ratio of 0.1˜0.35:1 or 0.35˜2:1 to obtain pretreated material; vacuum hot pressed sintering the pretreated material to obtain arsenic iron alloy. The vacuum hot press sintering process includes: placing the pretreated material in a vacuum environment; and sintering the pretreated material; in the sintering process, a pressure of 30˜50 MPa is applied to the pretreated material. The sintering process includes: heating the pretreated material from room temperature to 400˜500° C., and holding for 0.5˜1 h; and heating the pretreated material from 400˜500° C. to 600˜800° C., and holding for 0.5˜1 h. The present disclosure can obtain arsenic iron alloy with high performance and low leaching toxicity.
