20150137678 | LIGHT EMITTING DIODE BULB - A light emitting diode bulb is described, which includes a lamp housing, a light source module, a lampshade and a lamp cap. The lamp housing includes a first adjusting member and a second adjusting member. The first adjusting member includes a first engaging structure, a first acting surface and a second acting surface. The first acting surface and the second acting surface are located on the first engaging structure. The second adjusting member can be moved in relation to the first adjusting member. The second adjusting member includes a second engaging structure corresponding to the first engaging structure, and the second engaging structure has an upper opposing surface and a lower opposing surface. The light source module is disposed on the second adjusting member and can be moved as the second adjusting member is moved. The lampshade and the lamp cap are disposed on the lamp housing respectively. | 05-21-2015 |
20140376230 | LIGHT EMITTING DIODE BULB - A light emitting diode bulb includes a lampshade, a lamp housing, a heat sink, a driving circuit, light emitting diode modules and a lamp cap. The lamp housing is connected to the lampshade and includes a cup-shaped casing and a heat conduction part. The heat conduction part is disposed in the cup-shaped casing. The heat sink is disposed in the lampshade and includes a heat-dissipating shell and a heat-dissipating frustum. The heat-dissipating shell covers the heat conduction part. The heat-dissipating frustum includes a top surface, a bottom surface and four side surfaces. The heat-dissipating frustum includes an axis vertical to the bottom surface. An included angle between the axis and each of the side surfaces is smaller than 90 degrees. The light emitting diode modules are adhered to the top surface and the side surfaces and connected to the driving circuit. The lamp cap is connected to the driving circuit. | 12-25-2014 |
20130201682 | LAMPSHADE AND LED LAMP USING THE SAME - A lampshade and a light-emitting diode (LED) lamp using the same are provided. The lamp includes a lampshade main portion having a curved surface, and a radian of the curved surface of the lampshade main portion is greater than that of a semisphere. The lampshade main portion includes a plurality of lampshade plates. Each of the lampshade plates has a curved surface, and a radian of the curved surface of each of the lampshade plates is less than or equal to that of a semisphere. The lamp includes a base, the lampshade, and light-emitting diodes (LCDs). The lampshade is disposed on the base to form an accommodating space. The LEDs are disposed in the accommodating space to enable the light emitted by the LEDs to be diffused to outside of the LED lamp through the lampshade. | 08-08-2013 |
20130027926 | LIGHT SOURCE MODULE - A light source module includes a circuit board, a light-emitting diode, a lens, and a lamp screen. An upper surface of the lens has a first recessed portion including a flat surface and a curved side surface. The flat surface is at the center of the upper surface. The curved side surface surrounds the flat surface and stretches to the flat surface from a side surface of the lens to form the first recessed portion. A lower surface of the lens has a second recessed portion defining a recessed space and includes a curved surface and a sidewall portion. The curved surface is a convex surface and opposite to the flat surface. The sidewall portion surrounds the recessed space. An inner surface of the sidewall portion is concaved. The light-emitting diode is disposed in the recessed space. The lamp screen is used to diffuse the light passing through the lens. | 01-31-2013 |
