38results about How to "Increase the irradiation angle" patented technology

There is provided an article position management system which can determine where an article is present with high accuracy and manage the position of the article such that no article is left unchecked. Illumination sections (11-14) optically transmit pieces of positional information only to specific regions (lighting ranges (401-404)). A terminal device (31) receives the pieces of positional information transmitted from the illumination sections (11-14) and reads out article IDs from RFID tags (201-206) put on articles (101-106). The terminal device (31) sends the pieces of positional information and article IDs to a server (51) through a wireless LAN base station (41). The server (51) stores the pieces of positional information and article IDs sent from the terminal device (31) such that the pieces of positional information and article IDs are associated with each other.

The invention provides an LED bulb which comprises a lamp cap, a lamp holder, a light source module provided with an LED and a circuit board and a radiating column that is used for realizing omnibearing lighting angel by increasing the height of a light source and has the function of radiating; wherein, the lamp holder is a radiator, one end of which is connected with the lamp cap, and the other end is provided with the radiating column; the free end of the radiating column is fixed with the light source module; thus, the radiating column can heighten the position of the light source to shiftthe light source out of the lamp holder and increase the irradiation angle of the light source, thus realizing approximate 360-degree lighting effect of the LED bulb and improving the defect that thelight rays of the LED are blocked out by the lamp holder since the LED is installed at the rear part of a base plate of the lamp holder, close to the horizontal direction; the radiating column also has the function of radiating, so that the heat generated by the LED in the working period can be quickly transferred to the radiating aluminum lamp holder contacted with the air through the radiating column, thus enlarging the radiating area, fully guaranteeing the radiating requirements and the service life of the LED, reducing the weight of the high-power LED bulb and not increasing the size of the bulb.

A lighting fixture includes: a base; a plurality of optical sources attached on an upper surface of the base to emit light; a heat spreader attached to the base to radiate heat emitted from the plurality of optical sources; and a light diffusion lens disposed on the upper surface of the plurality of optical sources to refract light emitted from the plurality of optical sources and to increase an irradiation angle of light. In the lighting fixture, an irradiation angle of light emitted from an optical source is close to that of a general electric-light bulb and thus a light distribution characteristic of the lighting fixture may be improved.

A lighting device including: a light-emitting device unit including one or more light-emitting devices; a first reflector which faces the light-emitting device unit and reflects light emitted from the light-emitting device unit; and a second reflector which faces the first reflector and reflects light reflected by the first reflector.

The invention relates to the technical field of new energy. The invention further discloses a solar photovoltaic panel convenient to adjust including a mounting base, screw holes are formed in the twosides of the top of the mounting base; tightening screws are inserted into the two screw holes in a penetrating manner; a fixing circular ring is fixedly mounted at the top of the mounting base, a supporting triangular plate is arranged in the fixing circular ring, first sliding blocks are fixedly mounted at the three corners of the side face of the supporting triangular plate, and annular sliding grooves corresponding to the first sliding blocks are formed in the inner wall of the fixing circular ring. The invention discloses a solar photovoltaic panel convenient to adjust. According to thephotovoltaic panel, the supporting triangular plate can rotate by 360 degrees in the fixing circular ring through the first sliding block and the annular sliding groove, a user can conveniently adjustthe direction of the photovoltaic panel body, the requirements of the photovoltaic panel body for light in different directions are effectively met, and the working efficiency of the photovoltaic panel body is effectively improved.

The invention relates to an LED module provided with a heat dissipation structure, comprising a radiator and a plurality of LED units which are closely arranged on the radiator, the radiator comprises a heat-conducting seat and a plurality of heat dissipation fins which extend out from the heat-conducting seat; the heat-conducting seat is provided with heat-absorbent surfaces facing different directions; the LED units are closely arranged on the heat-absorbent surfaces and radiate toward different directions, so that the beam angle and beam scope of the LED module can be expanded.

The invention discloses an over-flow type sterilization and disinfection device, which comprises a casing. The upper and lower ends of the casing are threaded and installed with a quick-insert interface, and the end of the quick-insert interface is fixed with an elastic buckle. A first sealing ring is provided between the inside of the interface, and an annular pad is installed between the elastic buckle and the quick-plug interface; it also includes: a circuit board, which is embedded and installed on the inner wall of the housing in a ring-shaped position, and the circuit Ultraviolet lamp beads are fixed on the board, a transparent inner cylinder is fixed inside the outer shell, and double sealing rings are installed between the outer sides of the upper and lower ends of the transparent inner cylinder and the inner wall of the outer shell; the reflection unit is arranged on the transparent inner cylinder On the inner wall of the upper top surface, left and right slopes are respectively provided on the left and right sides of the top surface. The over-flow sterilization and disinfection device can conduct spiral diversion to the fluid, realize small obstruction and long circulation of the fluid, and simultaneously disperse and sterilize the fluid from all angles.

The LED lamp includes several LED elements, one planar circuit board, one LED fixing cover plate, one circuit board installing seat and one copper lamp base. The planar circuit board is first cut or punched to form multilayer ring holes to hold LED elements, and then fixed to the circuit board installing seat to form arced shape. The LED fixing cover plate is used to fixed the positions and irradiating angles of the LEDs. The LED lamp has wide emitting angle and homogeneous light strength and is suitable for lighting.
