Abstract

Disclosed is a streetlight having a xenon lamp in that a lamp assembly having a xenon lamp is formed at the existed streetlight, whereby lowering a power consumption and remarkably increasing the period of the lamp change. The present invention is to provide a streetlight having a xenon lamp in that the xenon lamp is formed therein, whereby emitting a lot brighter light with low power consumption. Also, the present invention is to provide a streetlight having a xenon lamp in that a ballast is built in a lamp assembly having the xenon lamp, so that the change of the xenon lamp can be easily performed and the lamp assembly can be easily applied to even the existed streetlight. Moreover, the present invention is to provide a streetlight having a xenon lamp in that a plurality of xenon lamps can be formed at one lamp assembly and the number of each lamp can be controlled, thereby adjusting the brightness thereof and another xenon lamp and ballast can be operated during the damage of the operating xenon lamp, thereby remarkably increasing the period of the lamp change.

Claims

1. A streetlight comprising:

a head having a main socket therein for supplying a power to the lamp assembly;

a pillar for supporting the head;

a ballast for applying a starting voltage to the main socket mounted into the head; and

the lamp assembly comprising a case as a body having a main plug for inserting into the main socket formed at one side of the case, a distribution socket for electrically connecting to the main plug formed at another side of the case, and a space formed at an inside thereof, and a xenon lamp for inserting into the distribution socket.

6. A streetlight as claimed in claim 1, wherein a coloring agent is coated on the inside of a jacket or a colored glass pipe is inserted into a jacket, thereby emitting a desiring color.

7. A streetlight as claimed in claim 1, wherein the xenon lamp is a mercury-free lamp.

2. A streetlight comprising:

a head having a main socket therein for supplying a power to the lamp assembly;

a pillar for supporting the head; and

the lamp assembly comprising a case as a body having a main plug for inserting into the main socket formed at one side of the case, a distribution socket for electrically connecting to the main plug formed at another side of the case, and a space formed at an inside thereof, a xenon lamp for inserting into the distribution socket, and a ballast for receiving a voltage from the main plug and applying a starting voltage to the main socket located in the space.

8. A streetlight as claimed in claim 2, wherein a coloring agent is coated on the inside of a jacket or a colored glass pipe is inserted into a jacket, thereby emitting a desiring color.

9. A streetlight as claimed in claim 2, wherein the xenon lamp is a mercury-free lamp.

3. A streetlight comprising:

a head having a main socket therein for supplying a power to the lamp assembly;

a pillar for supporting the head; and

the lamp assembly comprising a case as a body having a main plug for inserting into the main socket formed at one side of the case, a plurality of distribution sockets for electrically connecting to the main plug formed at another side of the case, and a space formed at an inside thereof, a xenon lamp for inserting into the distribution sockets, and a ballast for receiving a voltage from the main plug and applying a starting voltage to the main sockets located in the space.

4. A streetlight as claimed in claim 3, wherein the lamp assembly further comprises a switching portion for supplying a power to each ballast through the main plug or breaking the power formed at the space of the case.

5. A streetlight as claimed in claim 4, wherein the lamp assembly further comprises a detecting portion for detecting an operating status of the xenon lamp formed at the space of the case and a controller electrically connected to the switching portion, the controller serving to control the switching portion so as to immediately operate another xenon lamp when the controller receives a trouble signal of the operating xenon lamp from the detecting portion.

10. A streetlight as claimed in claim 3, wherein a coloring agent is coated on the inside of a jacket or a colored glass pipe is inserted into a jacket, thereby emitting a desiring color.

11. A streetlight as claimed in claim 3, wherein the xenon lamp is a mercury-free lamp.
