The present invention relates to a light and a method of manufacturing the light is coated with a reflective aluminum therein, and more particularly to light generated in the light emitting tube by coating a reflective material made of aluminum on a portion of the inner surface of the entrance side of a conventional light case. The present invention relates to a lamp having a reflective aluminum coated therein and a method of manufacturing the same, capable of reflecting and irradiating in a predetermined direction and adjusting an irradiation range of a locally limited area according to a coating area of a reflective material.

In general, the lamp is a device for obtaining the required illumination at night, to irradiate light in a locally limited area by irradiating light over a wide range, or by collecting light emitted radially from the light tube in one direction.

In particular, in the case of irradiating light to a locally limited area, a reflecting member such as a reflector or a reflector is provided separately from the lamp to reflect the light and collect in a specific direction in order to maximize the irradiation efficiency of the lamp.

However, although the development of the light emitting tube is continuously made in order to increase the irradiation efficiency of the conventional lamp, it is not actively developed for the reflecting member that plays a role in reflecting the light, collecting the light in a specific direction and improving the irradiation efficiency. It is true.

For example, in the case of a security lamp or a street lamp without a reflecting member, a high irradiation efficiency is required to secure a constant illuminance on the ground, but a part of the light generated from the light emitting tube is radiated to an unnecessary portion and thus the light is emitted. There was a problem in that the irradiation efficiency is lowered to reach the desired portion of the light to be reached.

On the other hand, in the case of a lamp equipped with a separate reflecting member can increase the irradiation efficiency by reflecting light in a desired direction, but a separate reflecting member must be provided, a lot of cost is generated according to the manufacture of the lamp, various forms There was a problem in that it takes a lot of time and effort to design and manufacture a reflective member suitable for the lamp. Furthermore, in the case of a lamp installed outdoors, such as a street lamp having a conventional reflective member, the reflective member is polluted by foreign matters such as dust, and thus the reflection efficiency of the reflective member is remarkably decreased, thereby cleaning the dirty reflective member. There was a problem that requires a lot of time and effort to replace or replace.

The present invention has been made in order to solve the problems of the prior art as described above, the technical problem of the present invention is to coat the reflective material on a part of the inner surface of the inlet side of the light case light generated in the light emitting tube without a separate reflective member To provide means for reflecting and irradiating in a predetermined direction.

In addition, by applying a different coating area of the reflective material coated on the inner surface of the light case to provide a means for adjusting the irradiation range for the limited area irradiated by the light emitted from the light emitting tube.

The present invention for solving the above technical problem,
