The invention provides a vehicle light module. The vehicle light module includes a plurality of light sources, a primary optical element, and a secondary optical element; the primary optical element includes a primary optical element body and a plurality of light incident portions, and the plurality of light sources correspond to the plurality of light incident portions in a one to one manner; theprimary optical element body includes a main reflection plate and edge reflection plates arranged on the left edge side and / or the right edge side of the main reflection plate; the plurality of lightincident portions have edge light incident portions on the left side and / or right side; at least a part of the light emitted from the edge light incident portions is reflected by the edge reflectionplates to the secondary optical element, and the remaining portion of the light is reflected by the main reflection plate to the secondary optical element, which increases the widening angle of the left side and / or right side of the vehicle light shape formed by the vehicle light module. Compared with the prior art, under the premise of achieving the same widening angle, the size of the primary optical element in the left-right direction provided by the application is smaller; therefore, the overall size and space occupation of the vehicle light module are reduced accordingly.

The invention provides a vehicle lamp module. The vehicle lamp module comprises a plurality of light sources and a primary optical element, wherein the primary optical element comprises a primary optical element body and a plurality of light incident parts which are arranged at the rear end of the primary optical element body and are arranged left and right; the plurality of light sources are in one-to-one correspondence with the light incident parts; the left edge side and / or the right edge side of the primary optical element body is provided with an edge reflection part; the plurality of light incident parts are provided with edge light incident parts located on the left sides and / or the right sides; at least a part of light rays emitted from the edge light incident parts are reflected by the edge reflection part and then are emitted out from the primary optical element, so that a vehicle lamp light shape formed by the automobile lamp module on the left side and / or the broadened angle on the right side can be increased. Compared with the prior art, the size of the primary optical element in the application is relatively small in the left-right direction under the premise of reaching the same broadened angle. Therefore, the size of the primary optical element in the left-right direction can be reduced while the broadened angle is enlarged.

The invention relates to a flow guiding structure of a fan, wherein the flow guiding structure of a fan is arranged on the fan, and comprises at least one flow guiding plate and at least one connecting part, wherein the flow guiding plate is spanned in front of the air outlet position of the fan; the flow guiding plate is positioned at the central side edge of the fan and is not overlapped with the center of the fan; the flow guiding plate extends outwards obliquely so as to introduce the air flow into the side edge of the fan; and the flow guiding plate is connected on the fan by the connecting part, therefore, the flow guiding structure of the fan provided by the invention can be combined with the fan or a ceiling fan, so that the air flow formed by the fan not only can converge on the axial direction of the fan, but also can disperse to the side edge of the fan moderately, furthermore, the air feeding angle of the fan can be increased greatly, and the convection efficiency at the periphery of the fan can be improved, so that the dispersing angle of the air flow of the fan can be increased.

A bending lamp comprises a substrate, an OLED (Organic Light Emitting Diode) light source assembly and an LED (Light Emitting Diode) light source assembly; the substrate is of a fan-shaped structure; the OLED light source assembly comprises a plurality of OLED sub-light-sources which are arranged on a reflective film; a gap which is of a fan-shaped structure is formed between every two adjacent OLED sub-light-sources; the LED light source assembly comprises a plurality of LED sub-light-sources which are arranged on the reflective film; every LED sub-light-source is located in the gap formed between the two corresponding OLED sub-light-sources; the plurality of LED sub-light-sources are arranged in the gaps respectively to form a fan-shaped structure. According to the bending lamp, the good heat dissipation performance and the bendable effect can be obtained through the reflective film, a heat transfer film and a heat dissipation film which are arranged in turn in a stacked mode and the diffusion angle of the light of the bending lamp can be increased due to the fact that every LED sub-light-source is arranged in the gap located between the two corresponding OLED sub-light-sources respectively to form the fan-shaped structure.

The invention discloses an integrated liquid crystal display module which comprises a machine shell. A reflection plate is fixed in a cavity of the machine shell and is provided with two or more than two light bars at equal intervals. Each light bar is provided with a plurality of LED lighting chips, a diffusion plate is arranged on the upper portions of the light bars, multiple layers of composite membranes are arranged on the upper portion of the diffusion plate, the composite membranes, the diffusion plate, the light bars and the reflection plate are fixed in the cavity of the machine shell from top to bottom, each LED lighting chip is provided with a convex lens, and the diffusion angle of each convex lens is 170 degrees. The integrated liquid crystal display module is convenient to install and convenient to produce in a large scale, reduces the whole thickness of the integrated liquid crystal display module, facilitates transportation, guarantees the strength of the machine shell on the condition that the wall thickness of the machine shell is not increased, prevents distortion and deformation, saves material quantities used in production, reduces weight, lowers cost and has good application prospects.
