ある。According to the present invention, an infrared reflective film with a maximum reflection spectrum of 0.8 to 1 Pm is formed on the outer bulb of a halogen lamp, and an infrared reflection film with a maximum reflection spectrum of 0.8 to 1 Pm is formed on the irradiation port of a reflector containing the lamp. Since we installed a filter with 1.1 to 1.7 #Lm, the radiation of heat rays was significantly reduced.
The temperature of the irradiated surface of the subject can be significantly lowered, and the infrared reflective film formed on the outer bulb of the lamp increases brightness compared to conventional halogen lamps, reducing power consumption for the same brightness as conventional halogen lamps. With the same power consumption, the brightness increases, making it particularly suitable as a spotlight for art museum paintings, store lighting, etc., and does not cause inconveniences such as discoloration of objects due to heat.
