LED Display, Fluorescent Lamp Replacement LED

Description

Buried type led lighting fixtures

The present invention relates to a lighting device using an LED (LED: light emitting display device), and more particularly, to a recessed LED lighting device having a structure in which a reflection shade provided in an existing embedded fluorescent lamp assembly is used as an LED illuminance enhancement and heat dissipation means. will be.

Conventionally, development of an illumination source that can replace fluorescent lamps has been actively progressed, and recently, research and development of fluorescent materials have been progressed to provide LEDs having high illuminance, and thus LEDs can replace fluorescent lamps. It is starting to attract attention as a lighting source.

Lighting devices with LEDs are usually manufactured in the form of bulbs, or in the form of matrix panels or bars.

As an example, Korean Patent No. 690227 and Korean Utility Model No. 282767 disclose a lighting device in which a plurality of LEDs are clustered to form a bulb.

In addition, Patent Nos. 811061 and 820942, and Patent Publication Nos. 2001-95865 describe a lighting device having a panel arrangement of a plurality of LEDs, and Patent Nos. 616123, 727791, and Utility Model No. 418900. Disclosed are a lighting apparatus in which a plurality of LEDs are arranged in a row to form a bar.

However, the above structure has a disadvantage in that it is difficult to use in place of a date fluorescent lamp in the existing fluorescent lamp apparatus, or can be replaced only by partially changing the structure.

LED lighting fixtures that can be applied to existing fluorescent lighting fixtures have also been proposed. For example, LEDs in the form of bars in transparent circular tubes, such as in Patent No. 612622, Utility Model No. 385920, and Utility Model No. 407435, are proposed. A lighting device is known which has a lighting device and finishes both ends, and this type of LED lighting device is a pair of pins corresponding to fluorescent terminal pins at both ends of a circular tube in which a bar-shaped LED lighting device is housed. It is proposed to have a structure that can replace the existing fluorescent lamp fixtures.

However, when the LED lighting apparatus is mounted on the socket of the existing fluorescent lamp fixture as described above, there is a problem that the light efficiency is not good for the following reasons.

Fluorescent light emits light on the entire circumferential surface of the circular tube, so the reflection efficiency does not decrease even if it is located slightly away from the reflecting lamp of the fluorescent light. When placed on the fluorescent lamp socket, the LED is placed at a low position at a considerable distance from the reflection shade, so that the light emitted in a substantially horizontal direction is displaced from the reflection shade, causing light loss.

Since the self-illuminance of the LED lighting device is lower than that of a conventional fluorescent lamp, it is necessary to improve the light efficiency by using a reflection lamp. In addition, since the LED emits a lot of heat during operation, the LED lighting device must also have a proper heat dissipation means.

Such conditions can be met by embedded fluorescent lamps provided in the indoor ceiling.

That is, the reflection shade of the conventional recessed fluorescent lamp can be suitably utilized as a heat dissipation means according to the arrangement of the LED.

Therefore, the present invention aims to improve the illuminance of the LED and use it as a heat dissipation means through the reflection lamp of the existing recessed fluorescent lamp, and to simplify the assembly of the device and to improve the appearance of the LED board. The purpose is to provide an LED lighting device.

The present invention embodying the above object is a buried LED lighting device that replaces the fluorescent lamp of the embedded fluorescent lamp lighting apparatus having a reflection shade with an LED array, the LED substrate in the center of the reflection shade heat conductive tape By attaching and fixing to the heat sink through the reflection shade, one or both ends of the LED substrate is disposed one-touch terminals with a clip contact is built in, so that the power line can be easily connected and connected, and the end cap Both ends of the optical filter are sandwiched and supported between the end caps by fixing both sides of the LED substrate with an elastic gripper to cover the periphery of the LED substrate.

In addition, another configuration of implementing the present invention is a buried LED lighting device in which the fluorescent lamp of the buried fluorescent lighting device having a reflection shade is replaced with an LED substrate arranged with an LED, interposing an aluminum strip in the center of the reflection shade Attaching and fixing the LED substrate, and providing one-touch terminals with clip contacts at one or both ends of the LED substrate so that the power line can be easily connected and connected, and an elastic gripper of the end cap Both side portions are fitted to each other so that both ends of the optical filter are sandwiched and supported between the end caps to cover the periphery of the LED substrate.

In addition, another configuration example for implementing the present invention is to form a center portion of the reflecting shade protruding in a rectangular shape in the longitudinal direction as a heat conduction support for attaching the LED substrate, one or both ends of the LED substrate The one-touch terminal with a clip contact is disposed in the power supply line to easily connect and connect the power lines, and the elastic gripper 18 of the end cap is fixed to both sides of the LED substrate to fix the optical filter between the two end caps. Both ends are sandwiched and supported to cover the periphery of the LED substrate.

In addition, the present invention may further include a configuration in which the heat dissipation efficiency of the LED substrate is improved by adding the wrinkles in the middle of the reflective shade to increase the surface area, while including the above-described configuration example.

The present invention of the above-described configuration removes the fluorescent lamp from the conventional recessed fluorescent lighting device, and attaches and fixes the LED substrate in the center of the remaining reflector shade, and end caps are attached to both ends of the fluorescent lamp lighting device at the same time as the optical filter As it is a covering structure, it is most suitable for replacing existing installed fluorescent lighting device with LED.

In addition, the light of the LED arranged on the LED substrate is scattered while passing through the optical filter and refracted and reflected in a predetermined direction by the reflection shade can provide an LED lighting device with low light loss.

And since the LED substrate is mounted and fixed at the center of the reflection shade via the heat conduction tape or the aluminum strip or the heat conduction support, both sides are a gap formed by the heat conduction tape or the aluminum strip or the heat conduction support at regular intervals, An elastic gripper can be attached and attached, and the optical filter covering the LEDs allows the light of the LEDs arranged on the LED substrate to be diffused. Such a configuration is easy to assemble the entire apparatus and to perform maintenance inspection after installation. It has the advantage of being easy.

In addition, by adopting the reflection shade as a heat dissipation means of the LED substrate, there is an advantage that can be implemented without a separate heat dissipation material, and even a simple structure to wrinkle the middle portion of the reflection shade can increase the heat dissipation efficiency by the reflection shade. There is an advantage to that.

In addition, since the optical filter covers the LED substrate, there is no external heterogeneity, so it is user friendly.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a perspective view showing a basic configuration of the present invention, which looks like a conventional recessed fluorescent lamp with a reflection shade 2 in which one sheet is bent into side serrated so that two to four lamps can be installed, and An end cap 4 attached to both ends of the reflection shade 2 in a lengthwise direction similar to a conventional recessed fluorescent lamp socket, and an optical filter 6 attached to each other across the end cap 4 in a transverse direction to diffuse light Equipped. The end cap 4 and the light filter 6 are actually attached to the central portion 8 of the reflection shade 2 as shown in FIG. 2, and the central portion 8 includes a plurality of LEDs 10 arranged therein. The LED substrate 12 is attached and fixed.

The LED substrate 12 has a structure in which the LED substrate 12 is attached to and fixed between the central portion 8 via a heat conductive tape 14 made of a heat transfer material or a thin aluminum strip. When the width of the thermal conductive tape 14 is set to be smaller than the width of the LED substrate 12, a gap is formed between both sides of the LED substrate 12 and the central portion 8 of the reflection shade 2, and the gap It is provided as a space into which the elastic gripper 18 of the end cap 4 is fitted.

In addition, the end cap 4 is attached to both ends of the LED substrate 10 through the elastic gripper 18 having its own elasticity by two rows of slits 16, and one side of the LED substrate 10 The one-touch terminal 20 is arrange | positioned at the edge part or both edge parts, and the power supply line W can be connected easily.

As shown in FIG. 3, the one-touch terminal 20 includes a clip contact 22 that is bent so that one end thereof is electrically connected to the LED substrate 12 and the opposite end forms a pair of opposing contacts. It has a structure in which the line W can be inserted and connected.

According to the above-described configuration, the reflection shade 2 basically shows the same shape and function as the reflection shade employed in the conventional recessed fluorescent lamp luminaire, but the central portion 8 of the reflection shade 2 has a strip shape. The LED substrate 12 is attached and the periphery thereof is covered and protected by the optical filter 8 so that light emitted from the LED 10 arranged on the LED substrate 12 is scattered while passing through the optical filter 8 to be uniform. The illumination light is changed to one illuminance, and the light diffused in this way is reflected from the surface of the reflection shade 2 so as to illuminate the room, thereby obtaining a soft illumination light without light loss.

In addition, this invention is not limited to the above-mentioned embodiment, For example, you may replace the said heat conductive tape 14 with an aluminum strip. In this case, when the thermal grease is applied to the upper and lower surfaces of the aluminum strip, a better heat dissipation effect is obtained.

Instead of the aluminum strip capable of substituting the heat conductive tape 14, as shown in FIG. 5, the center of the central portion 8 of the reflection shade 2 protrudes so as to have a rectangular cross section along the longitudinal direction ( It can also be implemented in a structure having 24). When the LED substrate 12 is mounted on the thermally conductive base 24, the thermally conductive grease interposes and attaches and fixes the thermally conductive grease.

The lighting device of the present invention utilizes the reflecting shade 2 as a heat dissipation means.

Accordingly, the heat dissipation capability of the reflective shade 2 may be increased by forming a corrugation 26 in the middle portion of the reflective shade 2 to expand the surface area.
