Description

Straight type LED fluorescent lamp {Straight type LED fluorescent lamp}

The present invention relates to a straight-type LED fluorescent lamp, and more specifically, to opaque treatment of the area where the light is not emitted from the LED by double extrusion of polycarbonate, by using an inner hole of the external connection pin provided in the socket of the discharge tube A straight LED fluorescent lamp is used to power an LED array.

With advances in technology, the amount of light emitted per watt applied to LEDs is increasing.

The increase in the amount of light is opening the way to apply LEDs, which are used as indicators for electronic and mechanical products, or small power indicators, to residential and industrial lighting devices. When using LEDs as residential or industrial lighting devices, LEDs have compatibility issues with conventional incandescent, fluorescent, metal, and other various kinds of lighting devices.

Most of the LEDs, except the recently commercially available Acriche models, are driven by direct current. Conventional lighting devices are mostly used by directly connecting to commercial AC, or by using a ballast that varies the output voltage and current of commercial AC.

In addition, many of the lamps currently used (mechanisms for storing lighting devices) are designed to suit the size of conventional lighting devices. Therefore, in order to use the LED as a lighting device, the shape must be determined according to the existing lighting device standard, and the AC power must be used as it is or converted to a DC voltage and a current suitable for the LED.

When converting AC power into DC voltage and current suitable for LED, a separate power supply is required. The power supply for driving the LED should be stored on the wall or ceiling, or be retrofitted to the existing lamp fixture.

If the power supply unit is housed in an LED lighting device, it must be inserted into the discharge tube forming the appearance of a straight tube, and the back of the board on which the ED is mounted and the power supply unit are visible through the transparent discharge tube. The appearance of is damaged.

In addition, there is a problem in that welding is required in order to electrically connect the substrate located inside the discharge tube and the socket such as a straight pipe.

Accordingly, it is an object of the present invention to provide a straight LED fluorescent lamp that does not damage the appearance of the lighting device when the LED and the LED-related components are stored in the discharge tube, using the double extrusion method.

In addition, another object of the present invention is to provide a straight-type LED fluorescent lamp that is electrically connected to the parts located inside the discharge tube without welding the socket such as a straight pipe.

The above object is, according to the present invention, an LED array having at least one LED, a discharge tube for receiving the LED array, the region in which the light is not emitted in the LED array by a double extrusion method is opaque treatment, and the discharge tube Provided at both ends of is achieved by a socket for applying external power to the LED array.

Therefore, the intuitive LED lighting apparatus according to the present invention does not damage the appearance of the lighting apparatus even after storing the LED and the components related to the LED in the discharge tube.

In addition, the intuitive LED lighting apparatus according to the present invention can electrically connect the LED parts and the sockets located in the discharge tube without welding, thereby increasing the reliability of the lighting apparatus and reducing the production cost.

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

Referring to FIG. 1, the external shape of a straight LED fluorescent lamp according to the present invention is similar to a conventional straight fluorescent lamp, and the length, diameter, and the sockets 120 and 130 of the discharge tube 110 may be a conventional straight fluorescent lamp. It has the same specifications as the discharge tube length, diameter and socket of the lamp.

That is, the straight-type LED fluorescent lamp according to the present invention can be used as it is mounted on the existing light fixture without the need to modify or change the existing light fixture.

Accordingly, the left and right sides of the discharge tube 110 are respectively provided with sockets 120 and 130 for receiving external power, and the sockets 120 and 130 have external connection pins 121, 122, 131, and 132 of standard specifications.

The discharge tube 110 is usually formed of a transparent material because it must transmit the light emitted from the LED to the outside. If the LED, and the power supply is inserted into the discharge tube 110, it is visible to the outside through the transparent discharge tube 110, damaging the appearance of the linear LED fluorescent lamp 100.

In order to prevent such a problem, in the present invention, the area where the LED is disposed in the discharge tube 110 and the power supply device is opaque, and the remaining area is transparent. The linear LED fluorescent lamp according to the present invention does not need to be formed of glass because it does not need to insert a gas for converting mercury, helium, or ultraviolet rays into visible light in the discharge tube 110. The discharge tube 110 is formed by extruding polycarbonate, and in order to have different transparency, double extrusion is used to avoid the disadvantage that the existing glass material is easily broken, and two transparency in one process. By implementing this, the manufacturing cost is also reduced.

Referring to FIG. 1, the region A of the discharge tube 110 is treated as an opaque region and the region B is transparent. The area A corresponds to the rear surface of the LED array and the area in which the power supply is disposed, and the rear surface and the power supply of the LED array are not visible to the outside.

The area B corresponds to the area where light is emitted from the LED. The range of the B region is formed with reference to the emission angle of the LED. The range of the B region will be described with reference to FIG. 2 together.

2 conceptually illustrates an example of setting a transparent region of a discharge tube.

Referring to FIG. 2, the transparent region of the discharge tube is determined by the angle of light emitted from the LED, that is, the angle of radiation.

In the drawing, when the emission angle of the LED is 90 degrees, the region B corresponding to the radiation angle of 90 degrees is allocated to the region B of the discharge tube, and the remaining region may be allocated to the region A.

If the emission angle of the LED is larger (e.g., 130 degrees), the area A is reduced and the area B is increased.

In FIG. 2, reference numeral 140 denotes a power supply device, reference numerals 150a and 150b denote LEDs, and reference numeral 160 denotes a substrate supporting the LED. In FIG. 2, since the back surface of the substrate 160 and the power supply 140 mounted on the substrate 160 are not visible to the outside through the discharge tube 110, the power supply 140 and the rear surface of the substrate 160 It is preferred to be treated opaquely.
