The reflector (30) also has a light condensing body (40) for condensing light that is emitted from the light emitting tube (20) to places other than the second reflector section (32) and irradiating the condensed light to a predetermined direction or region.

The invention discloses a distributed optical reflector of an LED (light emitting diode) street lamp. In street lighting application, height of a lamp pole can be lowered to reduce power and realize secondary energy conservation. The optical reflector comprises three groups of symmetrically connected reflecting cups, and each side of the reflecting cup groups includes a first reflecting cup, a second reflecting cup and a third reflecting cup. The first reflecting cup is formed by a reflector A, a reflector B, a reflector C and a high-power mounting hole J. The second reflecting cup and the third reflecting cup are the same with the first reflecting cup in structure. Efficient light and overall uniformity in different distances of streets are realized by the arrangement of different angles of reflection, different areas of light and the different power LED sources, average illumination is increased by 20-30%, the uniformity is increased by 40-50%, and application cost is lowered by 10-20%; and the optical reflector has significant social and economical benefits.

The invention relates to a substrate inspection device and a transmission illuminating device for the substrate inspection device. The substrate inspection device can prevent infrared light from an infrared light source from entering a camera without passing through the substrate, so that the substrate can be accurately inspected. The shape and arrangement of the infrared light source are set so that the field of view of the infrared light source of the charge-coupled device camera is covered by the field of view of the substrate of the charge-coupled device camera. Furthermore, by virtue of the Fresnel lens, the irradiation angle of the infrared light emitted from the light emitting diode element disposed near the edge of the infrared light source is deviated toward the edge direction of the substrate. In addition, the intensity of the infrared light irradiated from the infrared light source to the substrate on the edge region of the substrate is greater than the intensity of the infrared light on the central portion of the substrate.

The invention relates to the technical field of liquid crystal display, in particular to a backlight module and a liquid crystal displayer. The backlight module sequentially comprises a printed circuit board, a reflector plate, an LED light source and a diffusion plate from bottom to top. First protruding points are arranged on the light-in face, facing the LED light source, of the diffusion plate and around the projection, within the light-in face, of the LED light source. The first protruding points can conduct reflection diffusion on an illumination area, on the diffusion plate, of the LED light source, eliminate projection dark spaces and prevent light source gathering, so that the distribution of a light-emitting area on the diffusion plate is more uniform. Meanwhile, the LED light source can be independently controlled, local light control can be better achieved, and accordingly the display quality of a high-dynamic-comparison image is improved. The reflector plate can reflect leaking light again so that the light can irradiate the diffusion plate again, accordingly the utilization rate of the light source is increased, the light mixing distance is increased, and thinning design of the liquid crystal displayer is achieved easily.
