Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a projector, and more particularly to an improvement in a projector body provided at the front of a cylindrical body included in a socket.

Conventional general type floodlights include a projector body made of a material with relatively strong mechanical strength, such as stainless steel, at the front of a cylindrical body that has a socket for attaching a light source inside, and a It is constructed by attaching reflectors at regular intervals.

However, according to this structure, the reflectors are mounted inside the main body of the projector at regular intervals, so there are disadvantages in that the mounting structure of the reflectors requires a lot of work and the main body of the projector is large.

Therefore, recently, a projector that serves as both the projector body and the reflector and is made of stainless steel or aluminum, for example, has not been implemented.

However, if the projector body and reflector are both made of stainless steel, the projector main body can be made compact, but the reflectance is as low as 50 cents, making it impossible to effectively utilize the light from the light source. In addition, when constructed from aluminum, the reflectance is as high as 80 cents, making it possible to effectively utilize the light from the light source, and furthermore, the projector body can be constructed relatively compact, but its mechanical strength is weak. The thickness of the reflector must be considerably thick, and the corrosion resistance deteriorates.

The present invention has been made in consideration of the above points, and an object of the present invention is to provide a floodlight that can be easily and compactly constructed, has good reflectance, and can effectively utilize the light from the light source. .

The invention will now be described with reference to FIGS. 1 and 2. Figure VC,! -The projector body has a socket 2 for attaching a light source inside the IFi, and the main body of the projector is provided at the front of the three-barrel barrel 1, and is made of aluminum material.
A holder 4 made of a material with excellent mechanical strength, such as stainless steel; and a reflector 5 made of aluminum, which has the same shape and size as the holder 4 and is bonded to the inner surface of the holder 4. It consists of

A front glass is provided at the front end of the 6Iri projector main body 1, 7 is a rubber gasket provided on the outer periphery of the front glass 6, and 8 is a support leg that supports the cylinder 1 and the projector main body 3.

Next, the configuration of the projector main body in the above structure will be explained.

In order to construct the projector main body in the above structure, first, the holder 4 is made of a stainless steel material that has relatively strong mechanical strength and excellent corrosion resistance, and the reflectance is The reflector 5 is made of an excellent aluminum material. The reflector 5 is configured to have the same shape and size as the holder 4.

After configuring the holder 4 and the reflector 5 separately, the reflector 5 is fitted into the holder 4 and mechanically joined to form the projector main body 3.

The front glass 6 is attached to the stepped portion 8 at the front end of the folded projector main body 3 via the gasket 7, and the end of the rear holder 4 is mechanically folded to easily support the front glass 6. can.

As described above, the present invention is made of a material having excellent mechanical strength, such as the main body of the projector being made of aluminum. Since it is constructed with an aluminum reflector that is fitted and bonded to the aluminum reflector, it is possible to maintain mechanical strength due to the action of the enclosing body, and has excellent corrosion resistance. There is an advantage that the light from the light source can be used effectively.

In addition, the projector body can be constructed easily due to the simple structure in which the reflector is fitted and joined inside the holder, and furthermore, since the reflector is fitted and joined inside the holder, the projector main body can be constructed in a small size. It has the advantage of being able to
