Abstract
A metal halide lamp whose bulb is half powdered comprising a bulb, an arc tube, a lamp cap and a stem. After been sealed, the bulb and the stem have a fixed connection with the lamp cap; the arc tube is arranged in the bulb and connects the stem via two wire supports; the bulb has a transparent main mirror wall. A layer of phosphor made from phosphor slurry is painted on the inner wall of the bulb at the opposite position of the main mirror wall; the arc tube is arranged between the phosphor layer and the transparent main mirror wall. The bulb can be spindle-shaped or a hollow axisymmetric body with a fan-shaped longitudinal section. When the arc tube burns, the ultraviolet having the wavelength of 253.7nm-365.6nm from the arc tube is converted the visible light by the phosphor layer, and at the same time, the visible light, emitted by the arc tube, which deviates the main mirror wall can be mirrored to the main mirror wall by the phosphor layer, so the light efficiency is greatly improved and the energy is saved. The length of the electrode at the end of the bulb can be changed, and the bulb can rotate when contacts the lamp holder to make the main mirror wall direct to the irradiated objects.

The foregoing description is done test relatively with the Metal halogen lamp of not dusting, and its test comparing data is as follows:
| 250W cell-shell half dusting Metal halogen lamp | The transparent cell-shell Metal halogen lamp of 250W | The former is than the latter's result | |
| Input voltage | 220V | 220V | The same |
| Input power (containing ballast) | 229W | 228W | Very approaching |
| Light is logical | 20496LM | 18787LM | High by 9.1% |
| Light efficiency | 89.5LM/W | 82.4LM/W | High by 8.6% |
| Color rendering index | Ra71 | Ra65 | High by 9.2% |
| Color tolerance is poor | 5.1SDCM | 9.8SDCM | Low 48% |
| Illumination (the high 10m of bar) | The high 10m of bar | The high 10m of bar | The same |
| The bar center | 86LUX | 45LUX | High by 91% |
| Radius 3m | 75LUX | 37LUX | High by 100% |
