20100096992 | LIGHTING DEVICE - The lighting device includes: a heat radiating part provided with a cavity that accommodates a part of a plurality of drive circuit components driving a light source module; and a base part provided with a cavity that accommodates another part (e.g., a transistor) of the drive circuit components. Then, the drive circuit components are accommodated in the cavity of the heat radiating part and the cavity of the base part. | 04-22-2010 |
20110104935 | CONNECTOR AND ILLUMINATING DEVICE EQUIPPED WITH THE CONNECTOR - A connector according to the present invention connects a conductive member such as a radiating section which radiates generated heat from a heat source functioning with supplied power and a power connection section which connects with an external power source supplying power to the heat source. | 05-05-2011 |
20120236573 | LIGHTING APPARATUS - A lighting apparatus includes LEDs and a light-permeable cover passing the light emitted from the LEDs and an anti-scattering film is arranged on the cover for preventing the scattering of fragments when the cover fractures. The anti-scattering film contains a dispersing agent for dispersing light. Since the anti-scattering film containing a dispersing agent is arranged on the cover, when the lighting apparatus is damaged by falling, the scattering of fragments of the cover is preventable, and the glare can be reduced because the light emitted from the LEDs are dispersed through the dispersing agent contained in the anti-scattering film. Since the anti-scattering film containing the dispersing agent is arranged on the cover, the deterioration of luminance flux is preventable as compared to a case of arranging on the cover a member for anti-scattering and a member for reducing glare separately. | 09-20-2012 |
20120293057 | LIGHTING APPARATUS - The lighting apparatus according to the present invention includes a thermal source such as a light source or a power supply unit and a heat releasing portion for releasing heat from the thermal source, and further includes the first heat radiation film formed by applying a coating material containing a heat radiating material on the surface of the heat releasing portion and curing the material. Since the first heat radiation film is formed by curing the material containing a heat radiating material, heat emittance by infrared is improved compared to the case with a heat radiation film formed by anode oxide coating (alumite treatment), thereby enhancing the heat releasing performance while maintaining the heat releasing performance by heat radiation for a long period of time because of the high resistance to damages. | 11-22-2012 |
20120293961 | LIGHTING APPARATUS - A lighting apparatus includes a light source, a power supply circuit supplying power to the light source, a heat radiating section made of electrical insulating material and radiating heat from the power supply circuit to outside air, and a heat conducting section conducting heat from the power supply circuit to the heat radiating section, and the heat radiating section and the heat conducting section are thermally connected. A weight reduction of the lighting apparatus is realized and a heat conduction from the heat conducting section to the heat radiating section is improved. | 11-22-2012 |
20120314420 | LIGHTING APPARATUS - A lighting apparatus includes a light source module, a heat sink holding the light source module and a light-permeable cover mounted to the heat sink and covering the light source module. The cover is adhered to the heat sink by an adhesive agent applied with a gap formed on at least one part between the cover and the heat sink. The inside and outside of the lighting apparatus can be communicated to each other due to the gap. Since the inside and outside of the lighting apparatus are communicated to each other, the problems of temperature difference and pressure difference between inside and outside of the lighting apparatus can be suppressed so that the occurrence of defects because of condensation and the like can be prevented. | 12-13-2012 |
20130070464 | LIGHTING APPARATUS - A lighting apparatus includes: an LED module; a heat sink releasing heat generated by the LED module; a cover covering the LED module; a cap; and an insulating member located between the cap and the heat sink. Further provided is a light source supporting body having a locking part locking into the heat sink so as to hold the LED module on the heat sink. The cover has a protruding part fitting and locking into the light source supporting body or the heat sink. In the insulating member, one end side has an inserted part locking into the heat sink, and the other end side has a connection part screwed into the cap. | 03-21-2013 |
20130077318 | LIGHTING APPARATUS - A lighting apparatus comprises: an LED module; a heat sink releasing heat generated by the LED module; and a light source supporting body having a locking part locking to the heat sink so as to hold the LED module on the heat sink. This avoids the necessity of screws used for attaching the LED module to the heat sink, and hence reduces the number of components and realizes easy attaching work for the light source. Thus, workability is improved in comparison with the conventional art. | 03-28-2013 |
20130082595 | LIGHTING APPARATUS - A lighting apparatus includes: an LED module; a power supply part supplying electricity to the LED module; a heat sink releasing heat generated by the LED module; a cap containing in the inside at least a part of the power supply part; and an insulating member located between the cap and the heat sink. In the insulating member, one end side has a connection part connected to the inside of the cap. The connection part has an opening part conducting heat from the power supply part to the cap. Since the opening part is provided in the connection part connected to the inside of the cap, a part of the power supply part is arranged in the inside of the cap without being blocked by the insulating member. | 04-04-2013 |
