Abstract

PURPOSE: To suppress the temperature rising of an introducing conductive sealed part to inhibit the disconnection of conductive foil by installing a cylindrical shielding body, surrounding the introducing conductive sealed part of a lamp and forming a light absorption surface inside thereof for absorbing light, inside of the top part of a reflecting body. CONSTITUTION: When a shielding body 4 with a light absorption surface 5 formed inside is installed, the temperature can be decreased. At the time of lighting a lamp 2, a part of heat reflected by a reflecting body 1 returns to the lamp 2 side. When the shielding body 4 is not installed, the sealed part 3 is exposed to the reflection heat to cause the temperature rising, but the reflection heat is blockaded by the shielding body 4 installed to face the sealed part 3. Thereby the temperature of the sealed part 3 can be considerably decreased, and the effect of the temperature decrease becomes further remarkable by the light absorption surface 5 installed on the inside of the shielding body 4, so that the life longevity of the lamp can be greatly improved.

(Function) A part of the lamp's heat reflected by the reflector tends to be directed towards its own sealing part, but since a shield is provided opposite this sealing part, this is prevented. In addition to being blocked by the shield body, the reflected light directed toward the inner surface of the shield body is absorbed by the light absorption surface and is not directed toward the sealed portion, thereby suppressing overheating of the sealed portion.

The reflector 1 is held together with the cover 10 by overlapping the opening edges of the cover and the reflector 1 and locking them with the inner S edge of the louver 22. Further, as described above, the shield body 4 is cylindrical in this embodiment and is made of aluminum, for example, and its outer peripheral portion is fixed to the top of the reflector 1 by means such as welding. Another method may be caulking. Moreover, although the light absorption surface 5 is formed by the black ring 8, the light absorption surface 5 may be formed by making the inside of the shield body 4 black. Further, the reflector 1 is formed by forming a reflective film having specific wavelength reflection characteristics such as infrared ray blocking and visible range on a metal substrate made of aluminum or the like. Alternatively, a normal mirror finish, satin finish, etc. may be used.

Next, the operation of the above embodiment will be explained. For example, as lamp 2, a halogen lamp of 250W or 500W
When the lamp 2 is turned on using a halogen cycle, the lamp 2 is turned on while performing a halogen cycle.

The temperature of the sealing part 3 needs to be as low as possible,
When the shield body 4 with the light absorption surface 5 formed inside was provided, the temperature could be reduced by about 9% compared to the case where it was not provided. For example, when using a 500-V halogen lamp, the temperature of the sealed part is 390°C and 350°C when the shield 4 is not provided and when it is provided, respectively.
Therefore, the temperature reduction effect when the shield body 4 was provided was remarkable. This is because when the lamp 2 is turned on, part of the heat reflected by the reflector 1 returns to the lamp 2 side.

If there is no shielding body 4, the sealing part 3 will be exposed to the reflected heat and its temperature will rise. However, since the shielding body 4 is provided facing the sealing part 3, The heat is cut off by the insulation body 4. As a result, the temperature of the sealing part 3 can be reduced considerably, for example by about 7%, but since the light absorption surface 5 is provided inside the shield body 4, the temperature reduction effect is It becomes even more noticeable. That is, since the shield body 4 is provided, the light from the lamp 2 is also projected inside the shield body 4.

As a result, a part of the light reflected inward reaches the sealing part 3. As a result, a slight temperature rise in the sealing part 3 is inevitable, and as mentioned above, the temperature decreases by only 7%, but since the light absorption surface 5 is formed inside the shield body 4, There was no reflected light from the lamp 2 on the inner surface of the shield body 4, so the temperature rise in the -layer was suppressed, and as described above, the temperature of the sealing part 4 could be lowered by about 9%.

In addition, in the above embodiment, cover 5. Heat sink 11° cover 10. Although we have explained the case where the looper 21 etc. are provided, even in the case of a device that does not have these and only has the socket 13 and support part on the reflector 1, such as a membrane type projector, it is necessary to attach the reflector to the reflector. A similar effect can be obtained by providing a similar shield 4 opposite the sealed portion 3 of the installed lamp 2.

(Effects of the Invention) As described in detail above, the present invention has a cylindrical structure in which a light absorption surface for absorbing light from the lamp is formed on the inside of the top of the reflector, surrounding the introduction conductor sealing part of the lamp. Since the shield is provided, light reflected from both the reflector of the lamp and the shield from the sealed part is blocked, and therefore the effect of preventing heating in the sealed part is significant, significantly extending the lamp life. This makes it possible to make significant improvements.
