Disclosed is a drug eluting balloon for a balloon catheter. The drug eluting balloon comprises a balloon body () and a coating (), and the coating () comprises a water-soluble adhesive layer (), an isolating layer () and a drug layer () from the inside out. After the drug eluting balloon is pushed to a diseased part, the balloon body () is expanded, and the water-soluble adhesive layer () dissolves due to scouring by a blood flow, such that the isolating layer () and the drug layer () are separated from an outer surface of the balloon body () and adhere to a blood vessel wall. The provision of the isolating layer () can effectively suppress the water-soluble adhesive layer () from removing part of the drug layer () during dissolution, and after the drug layer () adheres to and makes contact with the blood vessel wall, the isolating layer can also reduce the scouring effect on the drug layer () by the blood flow, thereby reducing the loss of drugs, allowing the drugs to be taken in by the blood vessel wall to the greatest extent, greatly improving the utilization rate of the drugs and improving the treatment effect while also preventing toxic and side effects brought about by large doses of the drugs. Moreover, the isolating layer () can also realize the slow release of the drug layer (), such that the drug layer () can provide treatment for a long time, and a good treatment effect can be obtained.

An automotive headlamp system and an automotive lamp. The automotive headlamp system comprises a light source, a primary optical element, an automotive signal lamp structure, and a secondary optical element arranged sequentially along the light emitting direction. The automotive signal lamp structure comprises a light-transmitting portion and a rotating shaft. The light-transmitting portion comprises at least one light-transmitting plate mounted on the rotating shaft which can be driven to rotate by the rotating shaft. By means of rotation, light from the light source exits from the primary optical element, then selectively passes through one of or none of the light-transmitting plates, and is then projected by means of the secondary optical element to achieve a corresponding signal lamp function. The light-transmitting plate mounted on the rotating shaft is used to replace an existing signal lamp, reducing the space occupied by the original signal lamp, decreasing the volume of a headlamp.

A system and method for controlling an exposure dose of a light source are disclosed. The system includes an LED light source, a light homogenizer, an energy detection unit and an exposure dose control unit coupled to both the LED light source and the energy detection unit. The energy detection unit includes an energy detector corresponding to the LED light source or the light homogenizer and an energy spot sensor corresponding to a wafer. By using the LED light source capable of producing UV light in lieu of an existing mercury lamp, the system is less hazardous and safer by eliminating the risk of discharging hazardous mercury vapor into the environment when the mercury lamp is broken. Moreover, exposure illuminance of the LED light source can be adjusted and the LED light source can be turned on/off under the control of exposure dose control unit to expose the wafer with high dose control accuracy, without needing to use a variable attenuator or an exposure shutter. This reduces the system's complexity and cost and increases its reliability.
