Provided is a reflective lamp comprising a bulb including a front lens section and a reflective mirror section fused thereto, said front lens section consisting of glass material containing neodymium and coated on its inner surface with a first thin film reflecting infrared rays and permitting visible lights to be transmitted therethrough, said reflective mirror section consisting of glass material containing no neodymium and coated on its inner surface with a second thin film reflecting visible lights. The lamp is capable of preventing the rise in the temperature of the bulb and yet providing a sufficiently high color rendering. Further, the lamp can offer the advantage of reducing its manufacturing cost.

A reflective lamp comprising a bulb and a filament contained therein, said bulb including a front lens section and a reflective mirror section fused thereto, said front lens section consisting of glass material containing neodymium in the range of 0.5 to 5.0% by weight as calculated in terms of Nd2O

A reflective lamp comprising a bulb and a filament contained therein, said bulb including a front lens section and a reflective mirror section fused thereto, said front lens section consisting of glass material containing neodymium in the range of 0.5 to 5.0% by weight as calculated in terms of Nd2O3 based upon the total weight of glass material and coated on its inner surface with a first thin film reflecting infrared rays and permitting visible light to be transmitted therethrough, said reflective mirror section consisting of neodymium-free glass material and coated on its inner surface with a second thin film reflecting visible light but transmitting infra-red rays therethrough.
