Description

Lamp reflecting shade apparatus for maintaining high lux of working surface uniformly}

The present invention relates to a lamp reflector device for maintaining a uniform high illuminance of the working surface, and more particularly, it consists of a structure in which a multi-stage reflector is combined to maximize the reflection and diffusion and concentration efficiency of light generated from the light source Uniform light of the work surface is irradiated and the light is diffused evenly to prevent glare, thereby improving the lighting environment of the workplace and maintaining the uniform light intensity of the work surface which can contribute to energy saving by improving the light reflection efficiency. Relates to a lamp reflector device.

Various lighting fixtures are applied to various types of reflection shades that reflect light generated from a lamp as a light source and concentrate a user's desired work surface.

Lamps generally have approximately 45% downward luminous flux and 55% upward luminous flux from the total luminous flux of the lamp. The lamp reflector ensures that the upward luminous flux generated by the lamps is not lost and is concentrated downwards, so that the reflector itself does not save energy, but by using the optimal reflector, the lamp reflector concentrates on the work surface that needs the light emitted from the lamp. It serves to raise.

In this way, the lamp reflector can indirectly save power by reducing the power requirements of the lamp and the ballast where the ballast is installed.

Various types of lamp reflectors have been developed to minimize the loss of light generated from the conventional lamps and to improve the concentration of lighting on the work surface.

Lamp reflector device 100 according to an embodiment of the present invention, the light generated from the light source 101, such as a metal halide lamp, LED lamp, ceramic lamp, sodium lamp, electrodeless lamp, reflected, diffused toward the working surface The first stage reflector 110, the second stage reflector 120, and the third stage reflector 130, which have a function of concentrating and surrounding the light source 101, are sequentially installed from an upper side to a lower side. A component such as a ballast is mounted on the upper side of the 101 and a main body 102 connected to a power source is coupled, and a lamp shade fixed to the multi-stage reflecting plates 110, 120, 130 and the main body 102 around the multi-stage reflecting plates 110, 120, 130. It consists of the structure in which 103 was provided.

The one-stage reflector 110 reflects the light generated from the light source 101 downward, the two-stage reflector 120 diffuses the luminous flux in a wide range, and the three-stage reflector 130 reflects the diffused luminous flux. It is configured to have a function of concentrating on the working surface through the opening of the bottom surface, the multi-stage reflector plate (110, 120, 130) has the following structure.

The first stage reflector 110 reflects an upward beam of light generated from the light source 101 in a downward direction to prevent a part of light emitted upward from the light source 101 from being used as illumination and being lost. It may be made of a material having excellent reflectance such as aluminum so as to increase reflection efficiency, and an inner surface thereof is made of a flat plate structure that reflects incident light as it is.

Most of the light incident and reflected by the first stage reflector 110 is reflected directly to the work surface through the lower opening, and the second portion of the second stage reflector 120 is coupled to extend from the bottom of the first stage reflector 110. ) Is reflected.

The interval between the first stage reflector 110 and the lamp which is the light source 101 may be set in a range of 20 to 50 mm depending on the type of lamp applied. That is, the one-stage reflector 110 serves to reflect the light of the light source 101 and guides it downward, so that the distance between the one-stage reflector 110 and the light source 101 exceeds 50 mm too far. When the reflection efficiency of the light is lowered, and the distance between the first stage reflector 110 and the light source 101 becomes too close to less than 20 mm, the first stage reflector 110 may be deformed and discolored by the heat of the light source 101. Because it can.

The two-stage reflecting plate 120 is coupled to be inclined at an angle downward from the bottom of the one-stage reflecting plate 110 to the outside downward, the inner surface of the light emitted from the light source 101 and incident from the first-stage reflecting plate 110 Embossing 121 for diffusing the reflected light incident downward is characterized in that formed in a regular shape.

In contrast, FIG. 5B illustrates an embossed 122 formed on the inner side surface of the two-stage reflective plate 120 with a convex portion 122a formed convexly toward the light source 101 and a connection portion 122b connecting them. In this way, when the embossing 122 is formed in the convex shape on the inner surface of the two-stage reflecting plate 120, the light emitted from the light source 101 is diffused upward from the convex surface can be lost There is a problem.

The three-stage reflecting plate 130 is coupled to be inclined at an angle downward from the lower end of the two-stage reflecting plate 120, the light emitted from the light source 101 and the incident light is reflected by the first stage reflecting plate 110 The light is reflected and the light diffused from the two-stage reflector 120 reflects the incident light and concentrates the light on the work surface.

The three-stage reflector 130 may include a two-stage reflector 120 and a three-stage reflector so that the light emitted from the light source 101 and incident light and the light diffused from the two-stage reflector 120 may be concentrated on the work surface. It is preferable that the acute angle θ2 between the extension lines of 130 is formed in a range of 20 ° to 25 °. The inner surface of the three-stage reflector 130 is composed of a flat plate like the one-stage reflector 110 so that the incident light is reflected as it is.

In this case, when the three-stage reflector 130 is used for narrow angles that collect light around 20 °, the acute angle θ2 between the two-stage reflector 120 and the three-stage reflector 130 is formed to be close to 25 °. At the same time, the vertical length of the three-stage reflector 130 is long, and when the three-stage reflector 130 is used as a diffusion type, the acute angle θ2 between the two-stage reflector 120 and the three-stage reflector 130 is It is preferable that the length is close to 20 ° and the vertical length is short.

On the inner surface of the three-stage reflector 130, as shown in Figure 4, the light incident on the three-stage reflector 130 is coupled to a predetermined interval along the circumferential direction so that the distribution of light irradiated to the working surface is uniform. An auxiliary reflector plate 140 reflecting a part may be further provided.

6 is a perspective view of the auxiliary reflector provided in the three-stage reflector.

The auxiliary reflector plate 140 is coupled to protrude in the direction toward the light source 101 from the inner surface of the three-stage reflector plate 130, and the first plate 141 is gradually wider from the top to the bottom And the second plate 142 form a predetermined angle θ and one side surface 143 is connected to each other, the three-stage reflective plate 130 on the contact surface (141a, 142a) in close contact with the three-stage plate 130 Through holes 141b and 142b may be formed to which fastening means (not shown) are coupled to each other. The first plate 141 and the second plate 142 are formed to have a wider width gradually toward the lower side to ensure a wider optical path to which light is incident and reflected, the auxiliary reflector plate 140 is a three-stage reflecting plate 130 Are disposed at regular intervals along the circumferential direction of), and the angle θ between the first plate 141 and the second plate 142 is set in a range of 30 ° to 60 °, and is incident to the auxiliary reflector plate 140. Light can be focused on the working surface with uniform illumination.

In the present exemplary embodiment, the auxiliary reflector plate 140 is illustrated as an example in which eight are arranged along the circumferential direction of the three-stage reflector plate 130, but the number of the auxiliary reflectors 140 may be set differently. Arranged as is also possible.

On the other hand, the surface of the first stage reflective plate 110, the second stage reflective plate 120, the third stage reflective plate 130 and the auxiliary reflective plate 140 further increases the reflectivity, the special coating layer (not shown) with low adsorption of dust Preferably formed. The special coating layer may be made of titanium dioxide (TiO ₂ ) or silicon dioxide (SiO ₂ ), which is a material having high reflectance and minimizing adhesion of dust. As the special coating layer is additionally formed, the adsorption of dust is minimized on the inner surface of each of the reflecting plates 110, 120, 130, and 140 even in a dusty working environment, so that the reflection effect can be maintained for a long time without separate cleaning management.

Hereinafter, the operation of the lamp reflector 100 configured as described above will be described.
