An LED light source device having an LED including an LED element as a light emission source and capable of possessing the same light distribution characteristics and luminance distribution as those of a common bulb having a coiled filament as a light emission source is provided. The LED light source device is also capable of providing the same light distribution pattern when it is used for a lighting fixture that utilizes a bulb as a light source, in place of a bulb. LEDs are disposed with respect to first light reflecting surfaces of paired hyperbolic cylindrical surfaces with a common focal line while LED elements of the LEDs are disposed at or near respective positions on the focal lines of the other hyperbolic cylindrical surfaces corresponding to the paired hyperbolic cylindrical surfaces.

In a LED lamp structure and an illuminating module thereof, the illuminating module includes a circuit board, a flat plate LED, an electrical pin and a packaging colloid. The circuit board has a length, a first and a second side formed at two sides of the length. The flat plate LED is fixed and electrically connected with the circuit board, bulges at the first side, and includes a substrate and at least one LED grain assembled on the substrate. The flat plate LED can emit omnidirectional light because the substrate is made of transparent material. The electrical pin is fixed and electrically connected with the circuit board and bulges at the second side. The packaging colloid covers the circuit board and the flat plate LED and has a rectangular plastic block. Thereby, the LED lamp structure can remain traditional appearance of a halogen lamp, for collecting and focusing light.

A light assembly includes a cover having an upper portion and a redirection portion. The cover has a longitudinal axis and a housing that is coupled to the cover. A lamp base is coupled to the housing. A circuit board is disposed within the housing. The circuit board has a plurality of light sources thereon. An internal redirection element is coupled to the circuit board and has a curvilinear shaped surface for reflecting a first portion of light from the plurality of light sources through the redirection portion of the cover and transmitting a second portion of light therethrough.

This invention is a device or module with a LED-type lamp of compact dimensions in order to be used in different illumination industries, such as the automobile, signaling or architectonic industries. The module includes elements for its easy and fast attachment, an efficient manufacturing as from a single plate and structures for the structural support and for heat diffusion. It can be directly attached in an application or in an insulation material support. Likewise, it has two different types of connections that may be used independently or jointly depending on the application.

A fill light and an electronic device are provided. The fill light includes a first reflector, a second reflector, a light-transmitting ring, and a light-emitting light source. The first reflector and the light-transmitting ring are located on a same side of the second reflector, and the light-transmitting ring surrounds the first reflector. The first reflector has a first reflection surface, the second reflector has a second reflection surface, and the first reflection surface is disposed opposite to the second reflection surface. A light-emitting side of the light-emitting light source faces the first reflection surface, and light emitted by the light-emitting light source is emitted from the light-transmitting ring after being reflected by the first reflection surface and the second reflection surface. The first reflection surface, the second reflection surface, and the light-transmitting ring are all rotationally symmetrical about a central optical axis of the light-emitting light source.
