A linear light source device comprises a wiring substrate in a rectangular shape and having a wiring pattern formed thereon, a plurality of light emitting elements arranged on the wiring substrate in a longitudinal direction of the wiring substrate and connected with the wiring pattern on the wiring substrate, and a sealing resin that seals the light emitting elements, wherein the linear light source device is to be arranged on a side surface of a light guiding plate to form a planar light source device, and an external connection terminal is arranged on a surface of the wiring substrate that is opposite to a surface of the wiring substrate where the light emitting element are arranged and in a central portion in the longitudinal direction of the wiring substrate, and connected with the wiring pattern.

Linear light source device and planar light source device

A light emitting device comprises a case having a space therein, the space defined by an inner bottom surface and an inner side surface of the case, a lead frame housed in the space, and having a bending portion bent along the inner side surface of the case, and a light emitting element electrically connected to the lead frame, wherein a rear surface of the bending portion is embedded in the case and a front surface of the bending portion is exposed from the inner side surface of the case so as to oppose the light emitting element, and wherein a projecting portion projected from the inner bottom surface and inclined to the inner side surface of the case is formed on the inner side surface of the case.

Light emitting device

The present invention provides a LED lamp module including a metal base, a flexible board mounted on the metal base and having a through hole, a surface mounted type LED lamp including a ceramic package having a projection portion on a back of the ceramic package, a LED chip mounted on the ceramic package, and a light output surface. The projection part is thermally connected with the metal base through the through hole, and the LED lamp is electrically connected with the flexible board through an electric conductive member at a portion other than the projection portion. The LED lamp module includes a cover covering a part of the LED lamp other than the light output surface and the flexible board and pressing the LED lamp.

LED lamp module

In a side surface light emitting type light emitting device mounted on the surface of a wiring board, the light emitting device comprises: a base body part having a reflecting case and a terminal holding part formed integrally with the reflecting case in the rear part of the reflecting case; and lead members inserted into the base body part, having a pair of connecting parts including base parts of the connecting parts drawn out from the lower surface of the base body part and bent along the lower surface and side bending parts provided in the base parts of the connecting parts and bent along the side surfaces of the terminal holding part and connected to a pattern of the wiring board; and is characterized in that the base parts of the connecting parts are provided with protruding parts protruding toward the center of the lower surface of the terminal holding part and cut-out parts are provided for accommodating the protruding parts in the lower surface of the terminal holding part.

Side surface light emitting device

Light emitting diode

In a light-emitting device including a base body portion which is configured by integrally forming a reflection case and a terminal holding portion provided at the rear portion of the reflection case and lead members to be inserted into the base body portion, portions of the lead members extracted outside of the base body portion are bent along the terminal holding portion to form a pair of connection portions to be connected to the pattern of a wiring board, respectively, a plurality of radiation plates are provided at the lead member. The plurality of the radiation plates are extracted from the same surface (lower surface) of the base body portion. Since the plurality of radiation plates are provided, at the time of being the radiation plates, the base body portion is prevented from being applied with an excessive force and the damage of the base body portion can be prevented.

Light-emitting device

There is provided an LED lamp unit comprising an LED lamp, a protective component for an LED lighting circuit, a circuit section and a case part, characterized in that the circuit section has a metal plate which is embedded in the case part with its surface partially exposed, a lead of the LED lamp is electrically connected to the exposed surface of the metal plate, and the protective component for the LED lighting circuit is connected to the metal plate at an opposite side to a side where the lead of the LED lamp is connected.

LED lamp unit

The invention is an indicator lamp for warning signal to a person who approaches the vehicle to steal a vehicle. The indicator lamp includes a lamp unit including a light emitting diode (LED). The indicator lamp includes a light guide including an elongated portion and a cover portion. The elongated portion receives a light from the LED at one end and conveys the light to a light emitting end. The cover portion covers the LED of the lamp unit and is integrally formed with the elongated portion. The light guide connects with the lamp unit at the cover portion. The indicator lamp prevents rainwater from the top from entering the lamp unit.
