Description

Wide angle high power LED Ceiling light for Marine

The present invention relates to a wide-angle, high-power LED ceiling lamp for ships, and more specifically, the wide angle provided by the ceiling lamp is capable of providing a wide light distribution angle of 140 degrees or more while providing a desired illuminance. It is intended to provide a wide-angle, high-power LED ceiling lamp for ships that can be used as a ceiling lamp even in a ship cargo hold of 5 to 7 m in height.

Ceiling lamps of various configurations are installed on ships.

When the ceiling height is 5~7m high, a flood light is usually used as a ceiling lamp.

However, in the case of the above-described FLOOD LIGHT, it is an expensive product, has a short service life of about 6,000 hours, and the ceiling light must be installed densely at a narrow angle of about 60 degrees with a distribution angle.

On the other hand, when the ceiling height is less than 3M, most ships also use LED type or fluorescent type ceiling lamps. In the case of LED, it has a long service life, so it is convenient for maintenance, and can provide high illumination with energy saving effect.

As a prior art for LED ceiling lamps, LED lighting fixtures mounted on the ceiling of Korean Utility Model Publication (U) 20-2016-0001457 (2016.05.04.), Korean Registered Patent Publication (B1)10-1643571 (2016.07) Various products such as ship LED lighting with overvoltage, overcurrent, surge and power supply protection functions of .28.) are provided.

In the case of the above products, the LED modules are arranged on a flat plate, and as shown in Figs. 7a and 7b, the light distribution angle is provided at a narrow angle of 120 degrees.

Therefore, if the ceiling height is applied to the cargo compartment of a ship with a high ceiling height of 5 to 7m, even if a product with high output is used, the number of ceiling lamps must be increased because the light distribution angle is a narrow angle of 120 degrees, so it is used due to increased facility cost and problems related to maintenance. It is not possible.

It is a perspective view showing another example applied, and FIGS. 7A to 7C are exemplary diagrams showing a wide-angle state of the light source according to FIGS. 3 to 6, respectively.

The wide-angle high-power LED ceiling light (1) for ships provided by the present invention can be mainly used for lighting in places where the ceiling is 5 to 7 m high, such as in a cargo compartment, and in particular, while using the same quantity as conventional floodlights, it has high brightness. I made it possible to provide.

Looking at the configuration of the wide-angle high-power LED ceiling lamp (1) for ships provided by the present invention, a pair of side plates (2) facing each other fixed to a cupboard, a main panel (2a) fixed to both side plates (2a), and a main panel (2a) ), the light source 3 of the LED tube or LED module configuration installed at the bottom of the light source 3, and the cover 4 through which light is fixed to the main panel 2a to protect the light source 3.

The main panel 2a has a rectangular plate shape with a narrow width and a long length, and an LED converter that converts AC power to DC power is built-in at the top, although not shown separately, so that power can be stably supplied. have. In addition, the side plate 2 to which both sides of the main panel 2a are combined has a portion that is coupled to the ceiling, and the side plate 7 is directly fixed to the tube-type light source 3 or the light source 3 is fixed. It has a configuration in which both ends of the fixed panel 5 are coupled.

The light source 3 installed on the lower side of the main panel 2a attaches the light source 3 of the LED configuration to the lower surface of the fixed panel 5 composed of a rectangular flat plate so as to conform to the main panel 2a.

In addition, the cover 4 is made of a material through which light irradiated from the light source 3 is transmitted, as mentioned above, and is preferably made of a synthetic resin such as acrylic or polycarbonate.

The cover (4) is combined in a configuration that can be separated from the main panel (2a), and is preferably combined with a hook-type coupling means (6) to assemble and maintain the cover (4) from the main panel (2a). ) To be easily detached.

In the case of the above configuration, the configuration is the same as that of a generally widely used LED ceiling lamp (or LED fluorescent lamp), and in the case of the LED used as the light source 3 attached to the fixed panel 5, the maximum light distribution angle is shown in FIGS. 7A and 7B. Since it is provided at 120 degrees as shown, it is difficult to illuminate a large area, so a large number of ceiling lights must be installed in order to apply to the cargo compartment of ships with a ceiling height of 5 to 7M. In most cargo ships, the conventional flood light (FLOOD LIGHT) I am using

In the present invention, while using the light source 3 of the LED configuration that provides the maximum light distribution angle at a narrow angle of 120 degrees as described above, it is improved to provide the light distribution angle at a wide angle of 140 degrees or more. Ceiling lamps (1) While minimizing the quantity, it is applied to the ceiling of the cargo compartment of a 5~7M ship to provide high-brightness lighting.

To this end, the present invention actively improves the configuration of fixing the fixing panel 5 that fixes the light source 3 to the main panel 2a, so that the light distribution angle provided by the wide-angle high-power LED ceiling lamp 1 for ships is 140 degrees. It was designed to be provided in a wide angle.

That is, the fixing panel 5 on which the light source 3 is fixed has at least two fixing surfaces 5a formed thereon so that different light distributions are provided.

As a preferred example of the fixing surface 5a applied to the fixing panel 5, as shown in FIG. 3, when viewed in a cross-section in the width direction, inclined surfaces 5a-2 bent upward on both sides with respect to the middle are formed symmetrically. , The light source 3 is coupled to the inclined surface 5a-2.

As a second embodiment of the fixing surface 5a applied to the fixing panel 5, as shown in FIG. 4, the horizontal surface 5a-1 and the horizontal surface 5a- The inclined surface 5a-2 bent upward to both sides of 1) is formed, and the light source 3 is coupled to the horizontal surface 5a-1 and the inclined surface 5a-2.

As a third embodiment of the fixing surface 5a applied to the fixing panel 5, as shown in FIG. 5, the inclined surfaces 5a-2 bent upward on both sides relative to the middle are symmetrical when viewed as a cross-section in the width direction. And the second inclined surface 5a-3 is further formed outward of the inclined surface 5a-2 on both sides, and the light source 3 is respectively provided on the inclined surface 5a-2 and the second inclined plane 5a-3. Combine.

As mentioned above, the light source 3 coupled to the fixed panel 5 is applied with an LED module configuration.

6 is a perspective view showing another example in which an LED tube type light source is applied to a ship's wide-angle high-power LED ceiling lamp provided by the present invention.

According to FIG. 6, unlike the above, the LED tube-type light source 3 is applied and does not require a fixed panel. That is, the LED tube type light source 3 is installed so that both ends are coupled and fixed to the side plate 7 coupled to both ends of the main panel 2a.

At this time, the light source 3 is installed in a horizontal state, and the light source 3 is installed in a symmetrical obliquely to both sides thereof.

The inclined surface 5a-2 is configured in a range of approximately 10 to 30 degrees, and more preferably configured in a range of about 20 degrees.

In other words, when the inclined surface (5a-2) is configured to be 10 degrees, the light distribution angle can be provided at 140 degrees, and when the angle is configured at 20 degrees, the light distribution angle can be provided at 160 degrees, and when configured at 30 degrees, the light distribution angle is provided at 180 degrees. can do. However, if it is configured at 30 degrees, it is difficult to provide high-brightness lighting due to the degree of overlapping of the light radiated to the lower part of the ceiling lamp.

7A to 7C are exemplary views showing the wide-angle state of the light source 3 according to FIGS. 3 to 6.

As shown, the inclined surface (5a-2) is configured to be 20 degrees to provide a light distribution angle of 160 degrees to a wide angle.It is a light source with double or triple light irradiated to the lower part of the wide-angle high-power LED ceiling lamp (1) for ships. The lights of (3) are superimposed to provide high-intensity lighting.

Therefore, when the present invention is used, it is possible to provide a wide irradiation angle of 140 degrees or more, to provide a desired illumination, and to a wide-angle high-power LED ceiling lamp (1) for ships in a ship cargo compartment with a ceiling height of 5 to 7 m. Even if it is used, high-intensity lighting is possible in the same quantity as the existing flood light, and energy savings and maintenance cost reductions can be expected.

It is the illuminance simulation data according to the 2nd and 3rd embodiments, and FIG. 12 shows an example of the arrangement of the ship's wide-angle high-power LED ceiling lamp and the existing ceiling lamp provided by the present invention.

As shown in Figs. 9 to 11, it is possible to provide a wider light distribution angle compared to the conventional fluorescent lamp, and a difference in light intensity occurs in a 2.3m height installation state, but the 5.5m height installation state is uniform without a shaded area in terms of light distribution. It can be seen that illuminance is provided.

In addition, as shown in Fig. 12, when applying a wide-angle high-power LED ceiling lamp to an installation area of 35*27m with LED 72W (Fixed Panel Second Example) & LED 144W (Fixed Panel Third Example), the number of light fixtures installed Since the number of fluorescent lamps can be reduced from 30 to 16, the number of luminaires can be drastically reduced.

In terms of economics, it was expected to save 44% when installing LED 72W (second example of fixed panel), and 30% when installing LED 144W (third example of fixed panel).
