- Other objects and advantages of the invention will appear to those skilled in the art to which it appertains as the description proceeds, both by direct recitation thereof and by implication from the context.
- According to this invention a retrofit ceramic metal halide lamps with magnetic choke integrated in the base of the lamp is provided for replacing mercury vapor lamps, low pressure sodium lamps and quartz metal halide lamps.
- Accordingly the present invention provides a retrofit ceramic metal halide lamp for replacing mercury vapor lamps, low pressure sodium lamps and quartz metal halide lamps. The inventive lamp gives white light and fulfills the conditions laid down in the new regulations such as minimum lumens/watt, lumen-maintenance and maximum allowed mercury content.
- In a preferred embodiment of the present invention, a retrofit ceramic metal halide lamp for replacing mercury vapor lamps, low pressure sodium lamps and quartz metal halide lamps is provided with a magnetic coil integrated in the housing of the ceramic metal halide lamp-base. It is connected to the arc tube and is in serial connection with the ballast.
- In another embodiment of the present invention, for replacement of HPS or quartz metal halide lamps, the retrofittable lamps are provided with a fuse integrated in the housing-base. The coil and other components are integrated in a housing-base and fixed to an outer bulb, wherein the metal halide arc tube is mounted.
- In a still another preferred an embodiment of the present invention, for replacing the mercury vapor lamps, ceramic metal halide lamps, the retrofittable lamps are provided with magnetic coil integrated with an ignition device. This ignition device can be a glow-bottle or an electronic circuit. The ignition device is a switching element and generates current steps.
- Further objects and advantages of this invention will be more apparent from the ensuing description when read in conjunction with the accompanying drawings and wherein:
-
FIG. 1 shows prior art HPS lamp with magnetic choke in the plastic part near the cap for operating on mercury vapor ballast; -
FIG. 2 shows a coil added in serial and integrated in the housing-base of the ceramic metal halide lamp-base according to the present invention; -
FIG. 3 shows an internal structure of the lamp according to the present invention; -
FIG. 4 shows an embodiment of the invention for replacement of mercury vapor lamps with an ignition device; -
FIG. 5 shows another replacement of embodiment of the invention suitable for HPS or quartz metal halide lamps. - Due to the high efficiencies of ceramic metal halide arc tubes, efficiencies above 100lum/W, the retrofittable lamps of the invention is constructed to provide lower power for the same light level. For example mercury vapor lamps have an efficiency of 50lum/W. So the power for making a replacement lamp according to the invention can be 50%, resulting in an energy saving of 50%. To operate these lower power lamps, another ballast is provided in addition to the existing ballast in the fixture with higher inductance. Referring to
fig. 2 , instead of changing the ballast in the fixture, a coil is added in serial and integrated in the housing in a ceramic metal halide lamp-base according to the present invention. The coil in the base together with the coil in the fixture limits the current through the arc tube. The coil in the housing-base is in serial with the ballast in the fixture, so the total impedance in serial with the arc tube goes up as shown infig. 3. Fig. 3 shows the internal structure of the lamp according to the present invention. This means that the current through the lamp goes down and the power in the lamp will go down. For operating these ceramic metal halide arc tubes, a starting pulse is needed. - Referring to
fig. 4 , in mercury vapor lamps no igniter is available in the fixture. Accordingly, an ignition device is integrated. This ignition device can be a glow-bottle or an electronic circuit. The ignition device is a switching element and generates current steps. By switching the current the coils in serial with the arc tube gives voltage peaks U=Ldi/dt, above 500V, which is high enough to ignite the lamp. When the arc tube is burning, the ignition device stops switching.
Referring tofig. 5 , for retrofittable lamps applicable for replacement of HPS or quartz metal halide lamps, there is no need to integrate an ignition device in the housing-base as it is already available in the fixture. For protection, a fuse is integrated in the housing-base. The coil and other components are integrated in a housing-base and fixed to an outer bulb, wherein the metal halide arc tube is mounted.
Thus in the retrofit lamps according to the present invention, an energy saving of around 30 percent is reached. A 170W lamp is for replacing a 250W mercury vapor lamp. An 85W is for replacing a 125W mercury vapor lamp. A 55W is for replacing an 80W mercury vapor lamp. The lamps have efficiency of about 88lum/W and have a color temperature of about 3000K with a color rendering of about 84.
