Description

Up-lighting LED Light Apparatus Using Reflecting Shade}

The present invention relates to an up-illumination LED fluorescent lamp apparatus using a reflection shade, and more particularly, by using the reflection shade to reflect the light emitted from the LED fluorescent lamp in an indirect lighting method, greatly improving the illuminance and power consumption through this The present invention relates to an LED fluorescent lamp apparatus of an upward irradiation method using a reflection shade that can greatly reduce glare according to the characteristics of a strong LED.

In general, a lot of bulbs or fluorescent lights are used as indoor or outdoor lighting. Such a light bulb or a fluorescent lamp had a short lifespan and had to be replaced frequently. In particular, a fluorescent lamp had a problem in that the illuminance gradually decreased due to deterioration over time of use.

Therefore, in recent years, lighting devices using LEDs having excellent controllability, fast response speed, high electro-light conversion efficiency, long life, low power consumption, and high brightness have been continuously developed.

One of the lighting devices, which is one of such lighting devices, mainly uses LED as a light source, and there are edge type surface lighting devices using a light guide plate, and direct type surface lighting devices in which a plurality of LED elements are arranged on a substrate. In the case of using the LED element, since a large number of light sources are required to maintain the uniformity of the surface light source, there is a problem in that power consumption that can replace the fluorescent lamp cannot be achieved, and the glare occurs excessively due to the straightness of the LED element. In order to prevent this, light is transmitted by using a translucent diffuser plate, so that the light transmittance is lowered, so that more power consumption is required to obtain an appropriate illuminance.

In addition, in the form of a fluorescent lamp, that is, a tube-shaped LED, an LED element is arranged in a tube to replace a fluorescent lamp. However, due to the characteristics of the LED device, the LED element must be placed on a heat sink. In order to illuminate the heat sink, the heat sink must be disposed to the rear side, which is also a direct lighting method, and there is a fear of vision impairment due to increased eye fatigue caused by glare.

The technical problem to be achieved by the present invention is to improve the illuminance using the reflection shade to reduce the power consumption, thereby reducing the cost of the facility, by using a reflection shade that can reduce the risk of vision disorder by reducing eye fatigue It is to provide an LED lamp of the upward irradiation method.

The objects of the present invention are not limited to the above-mentioned objects, and other objects not mentioned can be clearly understood by those skilled in the art from the following description.

According to an aspect of the present invention for achieving the above technical problem, a power supply device for supplying power to the tube-type LED fluorescent lamp is disposed on both ends and disposed on the upper surface of the receiving space of the luminaire body having a receiving space therein; The reflector is arranged in the lower portion of the reflector, the bottom of the reflector is bound to the power supply, the heat sink is positioned downward so that the emitted light is irradiated toward the reflector and the receiving space of the luminaire body at the bottom The upper side is open to cover and the lower side includes a luminaire cover provided with a transparent diffuser plate embossed to prevent light diffusion and direct irradiation.

According to another aspect of the present invention for achieving the technical problem, at least one locking jaw is formed in the upper surface of the luminaire main body is formed in the cross-section 'b' shape, the side portion of the reflecting shade by the locking jaw It is fixed, characterized in that the reflector is bound to the luminaire body.

The LED fluorescent lamp apparatus of the upward irradiation method using the reflector according to the present invention can significantly reduce the power consumption by significantly improving the illuminance, thereby reducing the facility cost and power cost, and reduce the fatigue of the eyes to reduce the risk of vision disorders. There is an effect that can be reduced.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings and the following description. However, the present invention is not limited to the embodiments described herein but may be embodied in other forms. Rather, the embodiments disclosed herein are being provided so that this disclosure will be thorough and complete, and will fully convey the concept of the invention to those skilled in the art. Like numbers refer to like elements throughout. It is to be understood that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. In this specification, the singular forms also include the plural unless specifically stated otherwise in the text. &Quot; comprises "and / or" comprising ", as used herein, unless the recited element, step, operation, and / Or additions.

Hereinafter, referring to FIGS. 1 to 4, an LED fluorescent lamp mechanism of an upward irradiation method using a reflector according to an embodiment of the present invention will be described in detail.

1 is an exploded perspective view of an LED fluorescent lamp of the upward irradiation method using a reflector according to an embodiment of the present invention, Figure 2 is a perspective view of an LED fluorescent lamp of the upward irradiation method using a reflector according to an embodiment of the present invention. 3 is a cross-sectional view of the LED fluorescent lamp apparatus of the upward irradiation method using a reflector according to an embodiment of the present invention.

1 to 3, the fluorescent lamp of the upward irradiation type using the reflector according to an embodiment of the present invention is largely the lamp body 10, the reflector 20, the tubular LED fluorescent lamp 30, and the lamp cover 40. It is configured to include).

The luminaire main body 10 is characterized in that the lower surface is opened to form a receiving space therein, both ends are provided with a power supply device 11 for supplying power.

The reflection shade 20 is disposed on the upper surface of the inner receiving space of the register body 10. The reflection shade 20 serves to reduce the power consumption by greatly improving the illuminance than simply using only one of the tube-shaped LED fluorescent lamp 30 by reflecting the light from the tube-shaped LED fluorescent lamp 30 to be described later.

As shown in FIG. 1, the upper surface of the luminaire body 10 is punched downward to form at least one locking jaw 12 having a cross-sectional shape of 'b', and the locking jaw 12 is formed by the locking jaw 12. The side portion of the reflector 20 is fixed to allow the reflector 20 to be bound to the luminaire body 10.

Conventionally, the fixing clip is fixed to the luminaire body using screws to fix the luminaire body and the fluorescent lamp, and is configured to fix the fluorescent lamp to the fixing clip, which requires a cumbersome process to couple the fixing clip to the luminaire body. As a result, problems such as an increase in cost and an increase in production period occur.

However, as shown in FIG. 1, the forming of the catching jaw 12 on one side of the luminaire main body 10 only requires a process of punching downward when the luminaire main body 10 is manufactured, thus making the production simpler and increasing the cost. However, there is an advantage that the problem of increasing the production period does not occur.

As shown in FIG. 3, the tubular LED fluorescent lamp 30 has an LED element 32 disposed on a heat sink 31, and light is not irradiated to a portion where the heat sink is attached due to the structural characteristics of the LED lighting device. In addition, the light is irradiated only in the direction in which the LED element is attached.In addition, due to the strong straightness of the LED element, when exposed to LED light for a long time, the risk of vision disorder and eye fatigue increase due to excessive glare. .

However, as shown in FIGS. 1 to 3, the LED fluorescent light fixture according to the exemplary embodiment of the present invention is configured such that the light of the tubular LED fluorescent light 30 is directed toward the reflector 20, that is, the heat sink 32 is downward. By disposing the light emitting device, the light emitted from the LED device 32 does not directly reach the eyes of the human body, thereby preventing glare and thus reducing the risk of blindness.

As shown in FIGS. 1 to 3, the luminaire cover 40 has a structure in which an upper surface thereof is open to wrap the luminaire body 10 from below, and a lower surface of the luminaire cover 40 has a diffusion plate 41. It is characterized by being attached.

In the conventional LED lighting device for surface lighting, light is scattered by using a translucent diffuser plate to prevent glare due to the straightness of the LED device. However, because the translucent material is used, the illuminance decreases, and in order to overcome the diminishing illuminance, the power consumption of the LED device has to be increased. Therefore, it has been pointed out that the problem of not reducing the power consumption enough to replace the fluorescent lamp.

However, the LED fluorescent light fixture according to an embodiment of the present invention can prevent glare while reducing the decrease in illuminance by using the diffuser plate 41 as a transparent material that has been embossed. That is, it allows light to be diffused and at the same time prevents direct irradiation.

This is because the light reflected through the reflection shade 20 is indirect lighting to prevent glare primarily, and secondly through the embossed transparent diffuser plate 41, the glare is further reduced without a large decrease in illuminance. This can be reduced.

Figure 4 is a view showing the illuminance test results of the LED fluorescent lamp device of the up-illumination method using the reflection shade according to an embodiment of the present invention and other lighting devices.

As shown in FIG. 4, two fluorescent lamps for indoor lighting used in a conventional office, etc., each having a power consumption of 32 W (less than or equal to Watt) are generally used, and in this case, illuminance is about 300 Lux at a distance of about 2 m. to be.

In the case of a surface-lit LED device used for replacing a fluorescent lamp, the power consumption is 49W, and the power consumption is 24% lower than that of the fluorescent lamp. It is possible to illuminate around 400Lux with less power consumption of 27W, which is 58% lower than that of existing fluorescent lamps. Can reduce power consumption by at least 2 times compared to cotton lighting, and the facility cost is also possible at half the level.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is clearly understood that the same is by way of illustration and example only and is not to be construed as limiting the scope of the present invention. I will understand. Therefore, the scope of the present invention should not be limited to the above-described embodiments, but should be determined by all changes or modifications derived from the scope of the appended claims and the appended claims.
