A method for monitoring physiological status of a vehicle driver is performed by a monitoring device connected to a physiological sensor and comprises steps of: (a) establishing a personal physiological database comprising steps of: periodically sensing the vehicle driver via the physiological sensor to obtain the physiological signals within an initial duration; obtaining a mean value and a standard deviation based on the physiological signals; and obtaining a tolerance range based on the mean value and the standard deviation, such that the personal physiological database stores the tolerance range; (b) sensing the vehicle driver via the physiological sensor to obtain at least one instant physiological signal after the initial duration; and (c) determining whether the at least one instant physiological signal is out of the tolerance range, such that an alarm is outputted when the at least one instant physiological signal is out of the tolerance range.

A multi-focus physiologic sensing device for condensing light is disclosed, comprises a multi-focus condenser has one first ellipse reflection member, and one second ellipse reflection member is arranged at an end of the first ellipse reflection member. The first ellipse reflection member has a first focus point thereon. The second ellipse reflection member has two second focus points thereon. A boundary between the first ellipse reflection member and the second ellipse reflection member has a first confocal point. Two lighting elements are respectively arranged on the two second focus points to generate light sources, that focus light on the first confocal point through the second ellipse reflection member, and then the detected object reflects the detected light source back to the first confocal point. Then, the detected light source is passes through the sensor from the first focus.

An image-partitioned display device for virtual image is disclosed. The display device comprises an image display unit, a refractive element, and a virtual image generation module. The refractive element is disposed between the image display unit and the virtual image generation module. Firstly, the image display unit generates at least one image, and then the refractive element refracts and partitions the image into a plurality of sub-images. Finally, the virtual image generation module receives lights of the sub-images to generate a large area virtual image or a plurality of enlarged virtual images. A volume of the virtual image generation module is reduced and all kinds of display information are provided by the image-partitioned technology.

A multi optical-route Head Up Display (HUD), comprising: at least an image display unit, to generate at least two input images, and project them respectively to a plurality of relay lenses, which adjusts reflection angle of said input signals and then transmits them to a virtual image generation unit, said virtual image generation unit produces a plurality of virtual images, and transmits them to a plurality of transmission mirrors, which reflects said virtual images to form a large area virtual image. Based on technical contents mentioned above, size of optical elements of lens and mirrors can be reduced drastically, so that said multi optical-route HUD can be miniaturized, to achieve image display range of large area, thus the moving vehicle information frame required completely overlaps outside view, as such effectively solving defects of a conventional single optical-route image display device capable of only providing small area image display.

A Head Up Display (HUD), comprising: an image display unit, to generate input images; a virtual image generation unit, to receive said input images and generate at least a virtual image; a rotation mechanism, used to make said virtual image generation unit to change its projection angle, to project virtual images to a plurality of transmission mirrors; and a plurality of transmission mirrors, used to receive said virtual images and reflect them into a large area virtual image. Advantage of said HUD is that, size of lens and mirrors is reduced, so said HUD is miniaturized, while realizing large area image display, such that information frame of vehicle match that of outside view, hereby solving problems of single optical route display device of the prior art, that is only capable of displaying a small area image rather than a large area image.

A converging illuminant device has a flat illuminant, a reflective layer and an enhancement film. The reflective layer abuts the flat illuminant, is grille-shaped and has multiple longitudinal strips and multiple lateral strips. The enhancement film is securely connected with the reflective layer and has an emissive surface. The emissive surface has multiple free-form curved areas, multiple longitudinal lines and multiple lateral lines. The longitudinal lines respectively align with the longitudinal strips. The lateral lines respectively align with the lateral strips. Because the reflective layer is grille-shaped, light definitely passes through central positions of the free-form curved areas, angles of refraction of the light are small and the light can be effectively converged. Consequently, illuminant efficiency and central luminous intensity are increased.

An LED luminescent device includes an LED light source, a reflector, a light shade and a projecting lens. The LED light source includes at least one LED element having a light-emitting surface emitting light. The reflector faces the light-emitting surface of the at least one LED element and has multiple reflection surfaces of different curvatures reflecting the light from the light-emitting surface of the at least one LED element. The light shade adjusts the light reflected by the reflector to provide a required light distribution pattern. The projecting lens project the required light distribution pattern. Thus, the device and a vehicle lamp including the device can prevent losing light energy.
