It receives the operating power from an external power supply (not shown) connected to the light emits light.

Here, the fluorescent lamp 112 is preferably provided with a pair at the lower side of the casing (C), the inside of the casing (C), such as a known ballast for supplying a stable operating power to the fluorescent lamp (112) It is preferable that the operation power supply unit be configured.

The reflection shade 120 is a kind of reflective plate cover made of a metal panel, provided in a state bent in the lower portion of the casing (C) to reflect the light of the fluorescent lamp 112 of the lighting unit 110 to the outside. By performing the, the lower portion of the casing (C) includes a flange 121 bent to both sides of the casing (C).

The reflector 130 may include an easily deformable reflector 131 formed of a thin film of a flexible material, and the reflector 131 may have a predetermined curvature with respect to the center of the fluorescent lamp 112. A curved shape is achieved.

Here, when the fluorescent lamps 112 are provided in pairs, the reflectors 131 are formed to have the same curvature on each of the fluorescent lamps 112 and are symmetrical, more preferably, the reflector 131 is previously formed. After forming a shape having a predetermined curvature through heat deformation or the like, or folding a central portion of the reflector 131 having a rectangular shape, the central portion is located at an upper portion between the pair of fluorescent lamps 112, and the central portion is Both ends corresponding to the have a curved shape with a predetermined curvature through the process to be stably positioned on one side of the pair of fluorescent lamps 112, which will be described later.

Therefore, according to the reflector 131, a reflecting material such as silver or chromium is plated or deposited on the reflecting surface facing the fluorescent lamp 112 to reflect the light generated from the fluorescent lamp 112 to a target object or a target space. The reflective surface may have a curved shape with a predetermined curvature with respect to the center of the fluorescent lamp 112, so that the reflective surface is formed with a flat or bent surface with respect to the fluorescent lamp 112 as in the prior art. It is possible to improve and thereby further improve the degree of illumination of the lighting unit 110.

In addition, the reflector 131, in order to concentrate the light generated from the fluorescent lamp 112 on the reflective surface, when the reflective surface has a predetermined curvature, the illumination unit 110 and the reflector 120 It consists of an ellipse or circular arc in which the 1st point 1p thru | or the 3rd point 3p is connected to the space between.

Here, the first point 1p is a portion where the vertical axis with respect to the center of the pair of fluorescent lamps 112 and the horizontal axis corresponding to the upper side of the outer diameter of any one of the pair of fluorescent lamps 112 meet. Thus, one end of the reflective surface is located at the base point. In this case, the first point 1p may have a height of about 8 to 15 mm from the central axis of the fluorescent lamp 112.

In addition, the second point 2p is a portion where the central axis of one side of the pair of fluorescent lamps 112 and the lower surface of the reflection shade 120 meet with one end of the reflective surface extending from the starting point.

It is the end point where the other end is located. In this case, the third point 3p has a height corresponding to the lower end of the fluorescent lamp 112.

Accordingly, the reflector 131 may include a vertical axis whose reflecting surface corresponds to a half portion of the separation distance with respect to the center of the pair of fluorescent lamps 112 and an outer diameter of one of the emitters of the pair of fluorescent lamps 112. The first point 1p at which one end of the reflective surface is positioned as a portion where the horizontal axis corresponding to the upper side meets, and the central axis of any one of the pair of fluorescent lamps 112 and the lower side of the reflective shade 120 meet. A second point 2p at which one end of the reflecting surface extending from the starting point is positioned as a portion, and the intermediate point is a portion where the outer diameter lower side of any one of the pair of fluorescent lamps 112 and the flange 121 meet. By having a curvature (or arc length) sequentially passing through the third point (3p) where the other end of the reflecting surface extending from the position is located, thereby preventing diffuse reflection by light generated from the pair of fluorescent lamps 112 Has been lighting a wide range Can.

Here, in the case where the reflecting surface of the reflector 131 has a curvature (or arc length) that sequentially passes through the first point 1p to the third point 3p, the reflector 131 is the three After fixing one point of the reference point, the other two points may be changed to achieve a predetermined curvature, or two points of the three reference points may be fixed and then another point may be changed to achieve a predetermined curvature. At this time, the variable reference point is preferably so as not to deviate significantly from the position of the point, otherwise, that is, the height of the first point (1p) and the second point (2p) is higher or lower than the corresponding range In this case, interference of light due to diffuse reflection occurs, which causes a darkening of the corresponding portion, that is, the portion of the reflective surface corresponding to the second point 2p, thereby lowering the reflection efficiency.

Therefore, the reflector 131 is diffuse reflection due to light generated from the fluorescent lamps 112 provided in pairs when the curvature passes through the first point 1p to the third point 3p in sequence. It can be prevented to illuminate a wide range.

The grip part 140 is to maintain the curved shape of the reflective surface of the reflector 131 at a predetermined curvature in the space between the illumination unit 110 and the reflector 120, the reflector 120 It is provided in the flange 121 of the longitudinal direction has a pair of grips (141, 142) so that one end of the reflector 131 is coupled to the flange 121.

Each side of the pair of grips 141 and 142 is spaced apart from each other by a predetermined size smaller than the sum of the thicknesses of the flange 121 and the reflector 131, and each other side is connected to each other. In addition, at least one of the pair of grips 141 and 142 is elastic, and more preferably, the pair of grips 141 and 142 are all elastic.

The process of coupling the reflector 131 to the flange 121 by the grips 141 and 142 of the grip unit 140 as described above is as follows.

First, when the reflector 131 and the flange 121 are inserted through the open side of the pair of grips 141 and 142, the pair of grips 141 and 142 are spaced apart from each other by an external force applied from the outside. In this state, one end of the reflector 131, that is, the surface and the flange 121 opposite to the central portion are inserted.

In this case, at least one of the pair of grips 141 and 142 has elasticity, so that a restoring force is accumulated in the elastic grip.

Subsequently, when the external force is released while the reflector 131 and the flange 121 are inserted between the pair of grips 141 and 142, the restoring force accumulated in at least one of the pair of grips 141 and 142 is applied. As a result, the pair of grips 141 and 142 are returned to their original state. Accordingly, the reflector 131 and the flange 121 are tightened by the elasticity of the pair of grips 141 and 142, so that the reflector 131 is flanged. It is to be stably coupled to the support 121.

As described above, as the reflector 131 is tightly coupled to the flange 121 by the grips 141 and 142 of the elastic grip part 140, the reflective surface of the reflector 131 is curved in a predetermined curvature. The lighting efficiency of the lighting unit 110 may be improved by being positioned in the space between the fluorescent lamp 112 and the reflecting unit 130 while being fixed.

In addition, as the reflector 131 is tightened or detached from the flange 121 by the grips 141 and 142 of the elastic grip part 140, coupling or releasing of the reflector 131 and the flange 121 may be easily performed. The maintenance work according to the installation and replacement of the reflector 131 can be easily made.

In addition, the pair of grips 141 and 142 are coupled to the pair of grips 141 and 142 as the surface of the reflector 131 is made of a slippery material when the reflector 131 is fastened to the flange 121. In order to prevent slipping from the position, one end of the slip prevention jaw 143 and the second grip 142 formed on the inner surface of the second grip 142 spaced apart from the first grip 141 by a predetermined interval. It further includes a coupling flange 144 extending at an angle opposite to the curvature angle of the second grip 142.

When the reflector 131 and the flange 121 are inserted, the slip prevention jaw 143 formed on the second grip 142 is positioned such that only the flange 121 is positioned toward the first grip 141. Only the reflector 131 is positioned on the side of the second grip 142.

Therefore, one end of the reflector 131 is prevented from being rolled out of the one end of the flange 121 and thereby the reflector 131 passes through the first point 1p to the third point 3p and thus the fluorescent lamp 112. The curved state to improve the reflection efficiency of the light generated from the can be kept stable.

As for the coupling flange 144 formed on the second grip 142, when the reflector 131 and the flange 121 are fitted, one end of the reflector 131 is positioned inside the second grip 142. It can be easily inserted.

 Accordingly, the slip preventing jaw 143 is formed on the inner surface of the second grip 142 among the pair of grips 141 and 142, and the coupling flange 144 is further formed on one end of the second grip 142, thereby providing the reflector 131. ), The curvature of the reflector 131 is prevented when the fastener is coupled to the flange 121, and the pair of grips 141 and 142 slip from the engaged position as the reflector 131 is made of a slippery material. Can be prevented to enable easier coupling.
