Description

Floodlight {Floodlight}

The present invention relates to a light emitter, and more particularly, to a light emitter with a small number of parts, easy to assemble, store, transport.

The light emitter refers to a lighting device that projects light in a specific direction outdoors by using an electric light emitting device such as a light bulb, and is mainly used as a night lighting device or a street lamp of a stadium.

Such a light emitter includes a light emitting device such as a light bulb, a reflector for collecting and projecting light emitted from the light emitting device only in a specific direction, a socket for fixing and supplying electricity to the light emitting device, and at least one of the light emitting device, the reflector and the socket. It includes a housing for receiving a portion therein.

In general, the light emitting device, the socket, the reflector, and the housing are each formed as separate members, and the light emitter is configured to assemble and install these parts, and when some components become old or malfunction in use, only the corresponding parts are replaced. Is configured.

In general, since the light emitting device generates a considerable heat, the socket should be made of a material having high heat resistance as well as electrical insulation. The most commonly used socket is a copper wiring structure formed in a ceramic shell. The reflector is composed of a material with high heat resistance and high light reflectance.

At the time of assembly, the socket is fixed to the inside of the housing using a screw or the like, the light emitting device is fixed to the socket by screwing or snap-fitting and the reflector is connected to the inside or outside of the housing using a screw or the like. do. In addition, the glass or dustproof glass may be attached to the housing or the reflection shade using a separate medium or a direct coupling method.

The housing not only accommodates at least some of the parts inside, but also draws a power supply line from the outside and connects it to the power supply wiring of the socket, and attaches the assembled floodlight to a light tower, pole, or street lamp pole. It should also serve as a conjugate. Therefore, the housing should be formed more firmly than any other component, and its structure is quite complicated because it is a multifunctional component.

Recently, the mainly used materials are light and durable aluminum alloys, and die casting is mainly used as a manufacturing method.

Since such a housing is easy to be divided into a plurality of parts due to its complicated structure, it is easy in terms of design or assembly, and thus, such a split molding method has been mainly used. The most common way is to open the back of the housing, ie the opposite end of the end to which the reflector is attached, and form a lid to block the open end as a separate member, after fixing the socket and connecting the wiring to such a member, To cover the open end with the lid.

However, since the transmitter is installed outdoors and is always exposed to rubella and rainfall, it is necessary to consider dustproofing and waterproofing of the interior of the housing. In addition, an increase in the number of parts to be molded by die casting leads to an increase in the number of molds, resulting in an increase in production cost. In addition, an increase in the number of parts means an increase in the number of assembling processes.

For this reason, in recent years, there have been many attempts to integrally form a housing, and a structure mainly used is a cylindrical structure in which one side is formed by an opening without a side wall and the other side is closed by a side wall. In such a cylindrical housing, a fixing part for fixing the socket is formed on the inner surface of the side wall of the closed side, and during assembly, the socket is inserted into the housing through the opening and the screw tightly tightens the side wall of the housing and the socket using a screw. .

In this process, the screw insertion hole formed in the side wall of the housing and the screw insertion hole formed in the socket must be precisely matched with each other. This matching is a difficult and time-consuming operation regardless of skill.

Therefore, an object of the present invention is to provide a floodlight having excellent dustproofness and waterproofness, low production cost, and easy assembly, storage, and transportation.

The present invention is also intended to provide a mounting aid that can be used for a light emitter to facilitate mounting of a socket for a cylindrical housing having only one open side.
