A light source device includes a lead frame, a first solid-state lighting chip, a first transparent encapsulation, a second solid-state lighting chip, and a second transparent encapsulation. The first solid-state lighting chip and the second solid-state lighting chip are respectively located at two opposite sides of the lead frame and electrically connected to the lead frame. The first transparent encapsulation and the second transparent encapsulation respectively encapsulate the first solid-state lighting chip and the second solid-state lighting chip.
Abstract:
A light chain includes a plurality of light emitting diodes (LEDs) electrically connected to each other. Each LED includes an LED chip having a first pole and a second pole, and a packaging layer encapsulating the LED chip. A first electrode has an inner end connected to the first pole, and an outer end extending to the outside of the packaging layer. A second electrode has an inner end connected to the second pole, and an outer end extending to the outside of the packaging layer. A third electrode has a first outer end and a second outer end located at the outside. The outer end of the first electrode and the first outer end cooperatively form a first plug; the outer end of the second electrode and the second outer end cooperatively form a second plug configured to attach to a first plug of an adjacent LED.
Abstract:
A light-emitting panel (50) includes a first light source (511) for emitting first light of a first single color, a second light source (512) for emitting second light of a second single color and a light guide plate (52). The light guide plate (52) includes a light incident surface (55) for receiving the first and second light and a display surface (53). A plurality of first microstructures (561) and second microstructures (562) are formed at the display surface (53).

Abstract:
The halogen-free resin composition comprises (A) 100 parts by weight of cyanate ester resin; (B) 5 to 50 parts by weight of styrene-maleic anhydride; (C) 5 to 100 parts by weight of polyphenylene oxide resin; (D) 5 to 100 parts by weight of maleimide; (E) 10 to 150 parts by weight of phosphazene; and (F) 10 to 1000 parts by weight of inorganic filler. By using specific components at specific proportions, the halogen-free resin composition of the invention offers the features of low dielectric constant, low dissipation factor, high heat resistance and high flame retardancy, and can be made into prepreg or resin film, and thereby used in copper clad laminate or printed circuit board.
Abstract:
An oral illuminator includes a solid state light-emitting element emitting light, an optical fiber, and a light diffuser. The optical fiber is arranged between the solid state light-generating element and the diffuser for transmitting the light of the solid state light-generating element to the diffuser. The optical fiber has an incident surface optically coupled to the solid state light-generating element, and an emitting surface optically coupled to the diffuser.
