| 20100277902 | LIGHT EMITTING DIODE LAMP FOR STREET LIGHTING WITH CHANGEABLE EMISSION COLOR - An LED lamp includes a curved lamp cover, a lamp case coupled to the lamp cover at one open end thereof, and a reflective plate fastened to the lamp case. The lamp case has an inner space in which a drive module for driving the lamp and a plurality of LED modules as light sources are mounted. The lamp case is divided into a first housing portion and a second housing portion. The first housing portion has a hollow space in which the drive module is fixedly installed. A mounting member configured to mount the LED modules thereon is installed in the second housing portion. Each of the LED modules includes a printed circuit board (PCB) substrate attached to the mounting member, a plurality of LED devices mounted on the PCB substrate, a lens seated on the PCB substrate to diffuse light from the LED devices, a spacer ring inserted between the PCB substrate and the lens, and a color film bonded to the lower surface of the lens facing the LED devices to determine the color of light from the LED modules. | 11-04-2010 |
| 20100277906 | LIGHT EMITTING DIODE LAMP FOR STREET LIGHTING WITH ADJUSTABLE EMISSION ANGLE - A light emitting diode (LED) lamp for street lighting includes: a curved lamp cover; a lamp case coupled to the lamp cover at one open end thereof and having an inner space in which a drive module for driving the lamp and a plurality of LED modules as light sources are mounted; and a reflective plate fastened to the lamp case to reflect light from the LED modules installed in the lamp case, wherein the lamp case is divided into a first housing portion having a hollow space in which the drive module is fixedly installed and a second housing portion in which a mounting member configured to mount the LED modules thereon is installed, and wherein direction adjusting members are respectively inserted between the mounting member and at least one of the LED modules in the second housing portion and each having a lower joining surface and an upper joining surface, the lower joining surface being flat such that the direction adjusting member contacts the mounting member and the upper joining surface being flat such that a printed circuit board substrate of the LED module is on the direction adjusting member, the upper and lower joining surfaces being not parallel to each other but forming a predetermined angle. | 11-04-2010 |
| 20100277920 | LIGHT EMITTING DIODE LAMP FOR STREET LIGHTING - A light emitting diode (LED) lamp for street lighting is provided. The LED lamp includes a curved lamp cover, a lamp case coupled to the lamp cover at one open end thereof, and a reflective plate fastened to the lamp case. The lamp case has an inner space in which a drive module for driving the lamp and a plurality of LED modules as light sources are mounted. The lamp case is divided into a first housing portion and a second housing portion. The first housing portion has a hollow space in which the drive module is fixedly installed.

| 20080207646 | Agent For the Prevention and Treatment of Liver Diseases Containing Pyrazolopyrimidine Derivative - The present invention relates to the pharmaceutical composition for prevention and treatment of liver diseases containing pyrazolopyrimidine derivative as all active ingredient. According to the present invention, pyrazolopyrimidine derivative has an excellent effect on inhibiting collagen synthesis in hepatic stellate cells and acts directly on the portal vein. Particularly, it may increase the diameter and the amount of blood flow of the portal vein, and finally decrease the pressure thereof. Therefore, pyrazolopyrimidine derivative can be used advantageously for prevention and treatment of hepatic fibrosis, liver cirrhosis caused by hepatic fibrosis, portal hypertension and various complications caused by portal hypertension. In addition, pyrazolopyrimidine derivative according to the present invention can reduce dosing frequency because of its long half-life, and therefore, has an advantage to improve the drug compliance of patients suffering from chronical liver diseases. | 08-28-2008 |
| 20090099357 | AGENT FOR THE PREVENTION AND TREATMENT OF PROSTATIC HYPERPLASIA COMPRISING PYRAZOLOPYRIMIDINONE COMPOUND - The present invention relates to an agent for preventing and treating benign prostatic hyperplasia (BPH) and lower urinary tract symptoms (LUTS) associated with BPH and a relaxant for relaxing urethral smooth muscle or prostatic smooth muscle comprising a pyrazolopyrimidinone compound as an effective ingredient. The agent in accordance with the present invention can provide nitric oxides by inhibiting the activity of PDE-5 that decomposes c-GMP, and the provided nitric oxides relax the urethral smooth muscle or the prostatic smooth muscle to lower the intraurethral pressure (IUP), thus treating BPH and LUTS associated with BPH. Furthermore, the time required for reaching a maximum blood concentration is shorter and the half-life is longer than the other PDE-5 inhibitors, thus reducing the frequency of administration. Moreover, the agent of the invention causing few side effects can be efficiently used as a safe drug. | 04-16-2009 |
