This utility model proposes a curved luminous screen for vehicle instrument panels, including an instrument body, which comprises an instrument shell, a mounting plate, and an OLED self-emissive screen. The mounting plate has a mounting cavity, and a control component is disposed between the mounting plate and the instrument shell. A glass cover is disposed on the mounting plate. The OLED self-emissive screen includes a liquid crystal display module, which comprises a polarizing film, a glass encapsulation layer, a low-temperature polycrystalline silicon layer, and a graphite sheet layer arranged sequentially. The use of an OLED self-emissive screen in the vehicle instrument panel only requires power to the illuminated pixels, resulting in 40%-50% lower power consumption than LCD. This is particularly suitable for extending the range of new energy vehicles. Furthermore, the self-emissive nature of OLED pixels allows for a contrast ratio of up to one million to one, with near-pure black, reducing light pollution, especially during nighttime driving, and improving the readability of instrument information. OLED covers the DCI-P3 wide color gamut, with superior color saturation and reproduction compared to LCD, making warning icons, navigation maps, and other details on the instrument panel clearer.

The utility model discloses a limit pin for preventing point discharge, which comprises a pin component, a locking head and a locking structure, the locking head is provided with an inserting hole, and one end of the locking head, which is far away from the pin component, is of a first spherical structure. The spherical structure is free of sharp edges and corners, electric field distribution at the position of an electric power fitting is improved, overhigh electric field intensity is prevented, a concentrated electric field at the head of an existing cotter pin is evenly distributed to a larger area, local electric field intensity is reduced, and noise pollution, light pollution and electric quantity loss caused by point discharge are reduced. When the pin assembly is inserted into the inserting hole in the axial direction, the locking structure can enable the pin assembly and the locking head to be locked or unlocked, locking is achieved, and the structure is convenient to mount and dismount.

This utility model discloses an ultra-wide-angle projection device below eye level, comprising a light source, a reflector, and a support. The reflector is mounted on a mounting surface and contains multiple reflective surfaces capable of primary reflection. Through specific reflective optical design and in conjunction with the unevenness of the ground or building surface, a portion of vertical illuminance is converted into horizontal illuminance, achieving both vertical and horizontal illumination for a three-dimensional lighting effect. This device can generate wide-angle, wide-range, and effective light distribution in multiple directions, including long distances, short distances, and both sides and edges, providing visually comfortable, highly uniform, and low-glare lighting while reducing environmental light pollution and decreasing the wattage and number of lamps. It is suitable for various indoor and outdoor applications, offering high energy efficiency and environmental friendliness.

This utility model belongs to the field of infrared lighting technology, and particularly relates to a linear infrared lighting fixture. This utility model provides a linear infrared lighting fixture, including a housing and a lamp plate, with the lamp plate installed inside the housing. It also includes connecting blocks, a connecting plate, and a mounting plate. Connecting blocks are connected to both ends of the housing, and the connecting plate is rotatably connected to the connecting blocks. The connecting plate is detachably mounted on the mounting plate. This utility model overcomes the inconvenience of maintenance in traditional linear infrared lighting fixtures, significantly simplifying the maintenance process and improving maintenance efficiency. The connecting plate is connected to the connecting block via a hinged connection, and its angle adjustment function allows for flexible alignment with the working area, improving the applicability and working accuracy of the lighting fixture.
