Description

Description: FIELD OF THE INVENTION The present invention relates to an illumination lamp device, and more particularly, to sealing a lamp with an arc discharge in a high-pressure gas such as a xenon lamp in a hard glass outer tube. The present invention relates to an illuminated lamp device.

(Prior Art) Conventionally, an illumination lamp device using a xenon short arc lamp has been used for projection or as a simulated solar light source device for light and weather resistance tests in combination with various filters. .

As described above, the illumination lamp device has often been used mainly for business purposes.

In recent years, besides the above-mentioned applications, attention has been paid to the bactericidal effect as a simulated sunlight light source, and there is a tendency to be used as a substitute for sunbathing in places with poor sunshine conditions in ordinary households.

In addition, there has been a demand that the color rendering properties as a simulated sunlight light source be used for a display in a small store or the like.

(Problem to be Solved by the Invention) The above-described conventional illumination lamp device has the following problems.

The xenon short arc lamp has an electrode portion covered with a quartz glass body. During handling of the lamp, when the hand touches the main body of the quartz glass and a fingerprint adheres,
There is a possibility that the portion to which the fingerprint is attached becomes brittle and the life of the lamp is shortened.

As in the past, when the use of the lighting lamp device is limited to business use, a person having specialized knowledge of the lighting device will handle the lamp. It was rare.

However, even if the lamp device is used in a general home or used for business such as the display, the operator is not necessarily a person having specialized knowledge of the lighting device. In such cases, handling may be inappropriate.

However, in a conventional illumination lamp device using a xenon short arc lamp, even when the quartz glass main body is exposed or covered, when the lamp is replaced or the like, the hand is held on the quartz glass. There is a problem that the structure is necessary to be touched, and the structure is not always appropriate for general household use or when handled by a person who does not have the specialized knowledge.

In addition, in order for the lamp device to be widely used for general purposes, as described above, the quartz glass portion may be damaged by excessive impact in consideration of the fact that a person with insufficient technical knowledge may use the lamp device. However, there is a problem that the handling must be further facilitated by taking measures such as preventing the fragments from scattering.

The present invention has been made to solve the above-mentioned problems and to achieve the object.

(Means and Actions for Solving the Problems) In order to solve the above problems, the present invention provides a reflector, an explosion-proof reinforced cover attached to a front surface of the reflector, and a reflector and an explosion-proof cover. It is characterized in that it comprises a xenon short arc lamp arranged at the center of the inside of the outer tube formed by the reinforcing cover and maintained airtight, and a base provided behind the reflecting mirror.

According to the above configuration, the lighting lamp device can be carried without directly touching the xenon short arc lamp, and the lighting lamp device can be attached to or replaced with a lamp, so that handling becomes easy. In addition, the xenon short arc lamp may deteriorate in material due to long-term use,
When it bursts due to excessive impact or the like, it has a function of blocking plosive sounds and a function of preventing fragments from scattering.
