A light emitting diode (LED) component includes a base having a main body and a wiring pattern. The main body defines an axis and includes two connecting surfaces respectively located at two opposite sides thereof, and a plurality of interconnected mounting surfaces surrounding the axis and connected between the connecting surfaces. The wiring pattern is at least disposed on the mounting surfaces and includes electrically insulated anode and cathode. A plurality of light emitting diode (LED) chips are disposed on the mounting surfaces. Each LED chip is electrically connected to the anode and the cathode.

LED component, LED module and method for manufacturing the LED component

A luminaire includes a base, a light-emitting unit, and a lamp cover. The base includes a first tube part, a second tube part having an inner diameter smaller than that of the first tube part, and a joint part connected between the first and second tube parts. An inner flow path is defined by at least the first tube part, the joint part, and the second tube part in a coaxial manner. The lamp cover is fixed on the base for covering the light-emitting unit. As such, air heated by the light-emitting unit flows out of the inner flow path to thereby allow cold air to be sucked into the inner flow path.

Luminaire having inner flow path

A luminaire is provided, which includes a first light source for providing an illumination light and a second light source passing through at least one image pattern for providing a patterned light. The first light source and the second light source are coupled to a driving circuit and covered by a lamp cover. The driving circuit is used to selectively drive at least one of the first light source and the second light source for providing the illumination light and/or the patterned light. A user may turn on or switch different patterns by touching a casing of the luminaire.

A light-emitting device includes a light-emitting element and a heat-conducting and electrically-insulating element. The light-emitting element includes at least one first conductive frame having at least one first electrically-conducting portion and at least one heat-dissipating portion, at least one second conductive frame adjacent to the first conductive frame and having at least one second electrically-conducting portion, a casing enclosing the first conductive frame and the second conductive frame, and at least one light-emitting chip disposed on the first conductive frame. The heat-conducting and electrically-insulating element includes a heat-conducting and electrically-insulating layer disposed on the heat-dissipating portion for insulating an electrical current from the heat-dissipating portion. Hence, the instant disclosure can plan a heat-conduction path and an electric-conduction path for the light-emitting chip to effectively increase the heat-dissipating efficiency of the light-emitting element due to the design of placing the heat-conducting and electrically-insulating layer on the heat-dissipating portion.

Light-emitting device

An illumination device having enhanced thermal dissipating capacity is provided. The illumination device includes a heat sink, an LED module, a cover, an LED driver, and a lamp base. The LED module is disposed at one end of the heat sink. The cover covers the LED module. The LED driver is in connection with the LED module, and includes a circuit board and at least one electrical contact member disposed on the circuit board. The lamp base is connected to the other end of the heat sink, and comprises an insulating unit, a first electrode, a second electrode and at least one contact port. The contact port is arranged on the lateral interior of the insulating unit, so that the electrical contact member of the LED driver may establish electrical connection with the lamp base.

Illumination device

An illumination lamp comprises a lamp body, a light-emitting module, a power supply module, and a circuit module. The lamp body defines an inner space. The partitioning unit is disposed in the lamp body for dividing the inner space into a first space for receiving the power supply module, and a second space for receiving the circuit module. Due to the presence of the partitioning unit, thermal convection between the first and second spaces is prevented to reduce adverse influence of a high temperature of the circuit module on the power supply module.

Illumination lamp

A current regulating circuit is for connection in series between a light emitting diode (LED) and a power source, and includes: a first resistive unit having a first resistance that is proportional to an operation temperature of the LED when the operation temperature is above a predetermined threshold temperature; and a second resistive unit connected in series with said first resistive unit, and having a second resistance that is inversely proportional to the operation temperature of the LED when the operation temperature is above the predetermined threshold temperature. When the operation temperature of the LED is above the predetermined threshold temperature, an effective resistance of said current regulating circuit attributed to said first and second resistive units is proportional to the operation temperature of the LED, and absolute value of a rate of change of the first resistance is larger than that of the second resistance.
