The LED lighting device includes an LED irradiating light onto an outside, a first lens having a lower part in which the LED is provided and having a convex form to diffuse the light incident from the LED through the lower part thereof to the outside, and a second lens provided on the outside of the first lens and having a rough surface formed on its inner surface to diffusedly reflect the light diffused through the first lens. | 05-13-2010 |
20100102694 | CIRCLE TYPE LED LIGHTING FLOOD LAMP USING NANO SPREADER - A circle type LED lighting flood lamp using a nano spreader is provided, which can provide a double heat dissipation structure formed by mounting an extended nano spreader having high heat diffusion on the inside of a circular type upper cover and making the extension parts of the nano spreader in contact with a heat dissipation portion in both directions, and prevent a heat dissipation plate from exposing to an outside by fixedly putting the upper cover on the outside of a heat dissipation member to improve the heat dissipation efficiency and the life span of the lamp. The circle type LED lighting flood lamp using a nano spreader includes LEDs, an LED mounting substrate on which the LEDs are mounted, a nano spreader having one side that is in contact with the LED mounting substrate and the other side that is extended for a specified length to form extension parts, an upper cover having inner heat dissipation pins that are in contact with the extension parts of the nano spreader, an upper cap fixed to an upper end of the upper cover, a lower heat dissipation member inserted into the inside of the upper cover and having an inner surface that is in contact with the extension parts of the nano spreader and an outer surface that is in contact with an inner surface of the upper cover, and a lower lens fixed to a lower part of the lower heat dissipation member. | 04-29-2010 |
20100097799 | LED LIGHTING FLOOD LAMP HAVING DOUBLE HEAT DISSIPATION PLATE STRUCTURE USING NANO SPREADERS - An LED lighting flood lamp having a double heat dissipation plate structure using nano spreaders are provided, in which the double heat dissipation plate structure is formed by installing the nano spreaders having high heat diffusion inside the lamp and forming heat dissipation plates on upper and lower parts of the nano spreaders, and heat dissipation pins are arranged in zigzag on the upper part of the upper heat dissipation plate, so that the heat dissipation efficiency is maximized, and the lamp has a slim external appearance without being limited in installation space. The LED lighting flood lamp includes LEDs, an LED mounting substrate on which the LEDs are mounted, nano spreaders mounted on an upper side of the LED mounting substrate, an upper heat dissipation plate fixed to an upper side of the nano spreaders and having a plurality of heat dissipation pins formed on an upper surface thereof, a lower heat dissipation plate fixed to a lower part of the LED mounting substrate, and a diffusion lens plate fixed to a lower part of the lower heat dissipation plate. | 04-22-2010 |
20100091487 | HEAT DISSIPATION MEMBER HAVING VARIABLE HEAT DISSIPATION PATHS AND LED LIGHTING FLOOD LAMP USING THE SAME - A heat dissipation member having variable heat dissipation paths and an LED lighting flood lamp using the same are provided, which can maximize heat dissipation effect by widening an air contact area and making air flow rapidly, seek a waterproof effect and prevention of a scald due to contact with a high-temperature heat dissipation plate, and prevent the reduction of heat dissipation efficiency caused by foreign substances by keeping wings of the heat dissipation plate not exposed to an outside. The LED lighting flood lamp using a heat dissipation member having variable heat dissipation paths includes LEDs, an LED mounting substrate on which the LEDs are mounted, a heat dissipation member having a lower part to which the LED mounting substrate is fixed and provided with the variable heat dissipation paths formed thereon, an upper cap fixed to outer surfaces of heat dissipation plates of the heat dissipation member; a fixing ring member fixed to the lower part of the heat dissipation member to achieve inflow of outside air, and a lower lens fixed to a lower part of the cap. | 04-15-2010 |
