At this time, the base portion 160 has the support portion connecting terminal 161 is formed in the central region, the plurality of second discharge

metal connecting terminals

162, 163 are formed on the outer periphery.

In addition, since the

ground fixing grooves

211, 212, and 213 of the grounding part 200 are portions in which the

connection terminals

161, 162, and 163 of the base part 160 are inserted and grounded, the connection terminals 161. , 162, 163).

An elastic part 164 having an elastic force is formed at the end of the support part connecting terminal 161 by a spring 165, and the ground fixing groove 211 where the support part connecting terminal 161 is grounded also has a spring 214. It may be formed so as to offset the vibration caused by the external force.

Here, the spring 165 is formed in the support connecting terminal 161, the spring 214 is interposed in the ground fixing groove 211, the luminaire of the present invention is the

Here, the discharge tube 120 is damaged by the internal pressure when the xenon gas is consumed to the end of its life, the lighting device of the present invention is provided with each discharge tube 120 inside the independent appearance (110) As the discharge tube 120 emits light sequentially, there is an advantage in that the service life can be significantly increased.

At this time, since the discharge tube 120 does not affect other appearances when heat is emitted to the outside by light emission, the effect of the discharge tube 120 according to the emission of one discharge tube 120 is minimized. There are advantages to it. That is, in the conventional configuration in which two or more discharge tubes are placed in one exterior, the plurality of discharge tubes 120 may extend in the longitudinal direction of the exterior 110 so as to minimize the influence of the other discharge tubes according to light emission of one discharge tube. Although there was no choice but to be spaced apart from each other, this configuration caused a problem of using parts of different specifications in the manufacturing, there was a problem that is somewhat different in the light irradiation area. The present invention aims to solve this problem by using an independent appearance.

A plurality of ignition units 310 are provided in the ballast 300 to supply a starting voltage to the plurality of discharge tubes 120, and the plurality of ignition units 310 switches to adjust electrical signals to be sequentially operated. The unit 320 is provided.

The other ignition unit 310 is operated by this to supply power to the other discharge tube 120 to emit light.

More specifically, the ballast 300 is always supplying (+) power to the support unit 150 side, by the control of the switching unit 320 one ignition unit 310 located in the upper side in the drawing discharge tube ( When the negative power is supplied to the 120, the discharge tube 120 located above emits light.

If the discharge tube 120 located on the upper side of the drawing breaks with time, the other one ignition unit 310 located on the lower side in the drawing under the control of the switching unit 320 is discharged to the discharge tube 120 (-). The electric power is supplied, and the discharge tube 120 positioned below emits light.

Accordingly, the lighting apparatus of the present invention can use a plurality of lighting apparatuses as many as the number of the discharge tubes 120 without using a single lamp assembly 101, and can significantly increase the service life of the lighting apparatus. The timing is also increased, which saves the cost of maintenance and replacement.

In addition, in order to extend the life of the

lamp assemblies

101 and 102, the lamp assembly 101 which is turned on by date and the lamp assembly 102 which are turned off may be operated alternately.

In addition, since the lamp assembly 101 includes a plurality of lamps 100, the lamp assembly 101 may drive all of the lamps 100 in a lit lamp assembly 101, or may drive only one lamp, alternately. You may drive it.

On the other hand, as shown in Figure 6, unlike the one embodiment in the housing 10 according to the present embodiment, a heat shield reflecting plate 18 may be disposed in place of the heat shield wall 12, the heat shield reflecting plate ( 18 may be located outside the reflection shades 22 and 24.

Hereinafter, the rest of the configuration is the same as the above embodiment and a detailed description thereof will be omitted.

second rotation shafts

51 and 52.

Thus, when only one lamp assembly (101, 102) is operated, there is an effect that the light source can be more effectively irradiated to the irradiation area by adjusting the rotation angle of the reflection shades (22, 24).

In particular, the luminaire is installed in a high place on the ground, the operator can operate the angle of the

reflector

22, 24 wirelessly or wired remotely from the ground without the need to manually adjust the irradiation area.

In the present embodiment, the angle adjusting unit 50 is configured to simultaneously adjust a plurality of reflecting

shades

22, 24, but may be configured so that only one reflecting

shade

22, 24 can be adjusted individually.

Since the rest of the configuration is the same as the above embodiment, a detailed description thereof will be omitted.
