On the angular structure of the brightness of light pillars produced by ground-based point sources during snowfalls

Abstract: The results of experiments on the observation of light pillars from point light sources during weak snowfalls are considered. The approximations of the angular profiles for different viewing angles are obtained. The two-scale character of the light pillar angular structure is revealed.

Solar luminous energy collection conduction structure

Abstract: Disclosed is a solar luminous energy collection conduction structure. According to a collecting lens, a dual-shaft tracking system is adopted. A rail tool is fixed at the position where sunlight is provided all day. The collecting lens is installed on the rail tool. A collecting structure, a bend and a luminous flux structure are installed between the collecting lens and an object with optothermal required or a space with optothermal required. After shining on the collecting lens, the sunlight is collected and concentrated, a positive collection structure enables the sunlight collected and concentrated by the collecting lens to be changed into a light beam, the bend and the luminous flux structure enable the light beam ejected by the positive collection structure to be conducted to a negative collection structure which is arranged at the position tightly next to the object with optothermal required or the space with optothermal required, and the negative collection structure enables the light beam conducted by the bend and the luminous flux structure to be changed into a light pillar or divergent light, and then enables the light pillar or the divergent light to be ejected to the object with optothermal required or the space with optothermal required.

Reverse type light-harvesting device

Abstract: The utility model relates to a reverse type light-harvesting device, comprising an outer sleeve, a reflector, a top cover and a light source; the reflector is arranged at the bottom part of the outersleeve and has an opening which is toward to the to the top part, the light source is connected with a locating base by a connecting piece, the irradiating direction of the light source is opposite tothe opening direction of the reflector, and the locating base is connected with the outer sleeve by a bracket. In the utility model, the reflector leads light intensity emitted by a high-angle diffused type light source to be condensed and reflected, the diffused type light source and a light-harvesting device are reversely installed axially, the light intensity emitted from the top part of the light source is justly opposite to the light reflecting surface of the reflector, the light intensity within an effective angle at the top part of the light source is irradiated out along the forward direction after being condensed and reflected by a parabolic light reflecting surface of the reflector, so as to form a cylindrical light pillar and achieve the purposes of improving lighting effect and realizing uniform focusing and light harvesting; in addition, the reverse type light-harvesting device has simple structure and convenient maintenance, and can be widely applied to various lamps.

Adaptive keyboard light pillar

Abstract: An input device includes a display device configured to selectively modulate light to produce a changeable display image. The input device also includes a keyboard assembly disposed over the display device and including one or more depressible keys. Each depressible key includes a keycap having a light transmissive window; a light pillar between the keycap and the display device; and a light-turning layer between the light pillar and the keycap.

Rubber anti-collision column for traffic safety

Abstract: The utility model relates to a rubber anti-collision pillar used for traffic safety, which is characterized in that a pillar body made of rubber, a base and a pin roll which are made of rubber and a rotary joint are included The pillar body is connected with the base through the pin roll and the rotary joint, and an elastic rubber band is arranged between the pin roll and the rotary joint A crystal lattice reflective membrane of yellow and white paint is arranged on the outside surface of the rubber pillar The rubber anti-collision pillar is made of natural rubber and synthetic rubber and provided with a unique rubber elastic round pillar body and a rubber base The pillar body is connected with the base through an elastic rubber material, can conduct a tilt of 90 degrees within a range of 360 degrees, can bear shocks and extrusions, has strong weather resistance, can restore to the original shape after a collision without any damage, can protect vehicles from being damaged after a collision, has convenient shifting and fixing The rubber anti-collision pillar is durable, has light pillar body, and is safe and reliable
