Light-emitting diode (LED) illuminating lamp
Technical field
The present invention relates to a kind of light-emitting diode (LED) illuminating lamp, particularly a kind of can 360 the light-emitting diode (LED) illuminating lamp of degree rotation.
Background technology
After invention king Edison has invented bulb, human from using progressive century of candle and kerosene illumination to " electric light ".People are through this progress in more than hundred years, and illuminations of today has not had only osram lamp originally, in our daily life, and a large amount of for a long time " light fixtures " that rely on different designs of all kinds, different principle; Bulb, fluorescent lamp, incandescent lamp tube, Halogen lamp LED, LED light lamp have all become the part of our daily life.
Among these different illuminations, utilize light emitting diode (Light Emitting Diode; LED) as can the say so illuminations of the most popular at present, environmental protection of the LED light lamp of luminescence component.It has different size, different colours can supply design alternative, can bear than high impact forces, and it is slower to have brightness decay simultaneously, extremely low power loss, reach 50,000 to 100,000 hours service life, high advantages such as brightness of illumination, these all are that other light fixture is difficult to be equal to, and also are the welcome main causes of LED light lamp.
Because led lamp has plurality of advantages, various countries Da Chang drops into a large amount of research and development manpowers invariably, exploitation related application product and patent protection.U.S. Pat 5921660 promptly discloses a kind of rotatable design of led lamp, and its feature has comprised the supporting seat of two semicirculars in shape, in order to clamp light-emitting diode (LED) module, light-emitting diode (LED) module can be rotated in limited angle.Yet, in this patent, a plurality of LED light lamps are uniformly distributed in around the body of light-emitting diode (LED) module, the light scattering to all the winds that causes led lamp to send, when the user only needs illumination on a certain direction, just can waste the light of part.The pivoting mechanism of adding this patent is complicated, and part is of a great variety, increases the cost of manufacturing on foot.And light-emitting diode (LED) module can't be arbitrarily changed in the design of this led lamp, also increases the inconvenience on using.
Another U.S. Pat 5726535, disclosed another kind of rotatable led lamp, its feature comprises uses outward turning contact rotating manner, can 160 degree adjust the direction of irradiation, this patent is adopted the two-sided printed circuit board (PCB) that all has LED light lamp, make its direction of illumination directed forward and rear respectively, when the user only needs illumination on a certain direction, just can waste the light of part.And the two-sided setting that all has LED light lamp of printed circuit board (PCB) also can produce higher temperature, but this patent is not provided with any heat abstractor, and this may cause the shortening in LED light lamp life-span.In addition, the anglec of rotation of this patent is 160 degree only, can produce the dead angle in the rotation.And this patent is not the convenient modular design that changes at any time, so its improved space is arranged.
Comprehensive above-mentioned shortcoming if can design a led lamp, is improved the deficiency of above-mentioned two inventions, its illumination direction is concentrated pointed to the one side that needs big brightness, the dead angle of eliminating rotation overcomes the shortcoming that changes inconvenience, and heat abstractor is set, then be the target that those skilled in the art make great efforts.
