摘要： A lens and light source module include: a light receiving surface; a light distribution surface, along the optical axis direction set opposite to the light receiving surface; light receiving surface away from the optical axis center region to form N groups of projection, where N≥1; each with a first incident surface and a first reflective surface. The first incident surface is adapted to refracting light to the first reflective surface; the first reflective surface is adapted to reflecting light to a light distribution surface and refracting light to a display by the light distribution surface. The lens provided by the present invention enables the majority of light to be directed to the shelf in a targeted manner, which is conducive to achieving balanced light distribution and enhancing light efficiency.

摘要： A Fresnel lens in a lens body, the lens body is provided with a light incident surface and a light exit surface opposite to each other along a first direction, and the light exit surfaces are adjacently arranged in a second direction perpendicular to the first direction. There are several protruding teeth, and the protruding teeth are formed by an effective surface and an ineffective surface, and the ineffective surface is inclined at an acute angle relative to the first direction. The invention makes the light passing through the lens body reach the effective surface as much as possible, thereby reducing stray light and enhancing light efficiency.

摘要： A load short-circuit protection circuit of LED power supply includes a power supply end, a load end, a switching module disposed between the power supply end and the load end, and a sampling resistor set in series with the load end, and further includes a signal amplification module that collects the current change signal of the sample resistor, and a protection control module that receives a amplification signal of the signal amplification module and controls the on-off of the switching module according to the signal. The circuit can quickly magnify the subtle voltage difference changes on the sampling resistor and output them to the protection control module. The resistance value of the sampling resistance can be set very small to reduce the loss. Meanwhile, the selected devices are simple, with very fast response speed, low cost and high stability.
