Description

LED lamp unit {LED LIGHTING APPARATUS}

The present invention relates to an LED (LED) lamp device, and more particularly, the electrical coupling relationship between the LED module and the power supply line is stable to prevent connection defects in advance and to perform the assembly work quickly and conveniently at the same time In addition, the present invention relates to an LED lamp device capable of ensuring proper and stable illumination by preventing a poor irradiation of light by preventing foreign matter from being applied to the surface of an LED when forming a protective layer of a printed circuit board.

In general, incandescent lamps using electric energy have been mainly used as incandescent lamps that are warm in color and do not require accessories to be turned on, and fluorescent lamps having high efficiency and long lifespan compared to incandescent lamps.

However, fluorescent lamps also have a limited lifetime and have high power consumption. Recently, lighting lamps using light emitting diodes (LEDs) as light sources have been developed. The light emitting diode is smaller in size than the conventional light source, has a long lifetime, and has a good conversion rate to light energy even with a small amount of electrical energy.

1A is a perspective view for explaining a conventional LED lamp device, FIG. 1B is a sectional view taken along the line A-A of FIG. 1A, and FIG. 1C is a sectional view taken along the line B-B of FIG. 1A.

The conventional LED lamp device 1 shown in Figs. 1A to 1C is mainly used for signs, landscape lighting, etc., and is configured in a form in which a plurality of LED lamps are arranged at regular intervals on two power supply lines 2. . The conventional LED lamp device 1 has a lamp housing 11 having an accommodating space 11 a therein, an LED module 12 coupled to an upper portion of the lamp housing 11, and an LED module 12 lamp. Conductive fastening member 13 is coupled to the housing (11).

The LED module 12 has a shape in which the LED 12b is disposed on the printed circuit board 12a. A pair of fastening holes 12c are drilled on the printed circuit board 12a, and the fastening holes 12c are disposed on the printed circuit board 12a. The positive electrode terminal and the negative electrode terminal are formed, respectively. As shown in FIG. 1B, the LED module 12 includes a positive and negative power supply line in which a conductive fastening member 13 inserted through a fastening hole 12c is inserted into the lamp housing 11. It is connected to 2) and is electrically connected to receive power.

In addition, in the conventional LED lamp device 1, as shown in FIG. 1C, an epoxy resin is applied and cured on the upper surface of the LED module 12 to protect the printed circuit board 12a from impact or foreign substances and to ensure moisture resistance. Formed protective layer 14 is formed.

However, the above-described conventional LED lamp device 1 is fastened to the power supply line 2 after the conductive fastening member 13 is inserted through the fastening hole 12c of the printed circuit board 12 as shown in FIG. Since there is no separate guide member in the process, there are many difficulties in fastening such as being inserted at an angle or slipping on the insulating coating layer of the power supply line. In particular, when the conductive fastening member 13 is inserted into the power supply line 2 at an angle, the conductive fastening member 13 is not positioned at the center of the conductive line (usually composed of a plurality of fine copper wires) disposed therein, so that smooth power supply due to a poor contact is impossible. In case of severe or severe power, the power is not supplied, causing serious problems such as unlit.

In addition, the conventional LED lamp device 1 has the same height as the upper end of the longitudinal side wall 11a of the lamp housing 11 and the upper surface of the LED 12b as shown in FIG. Epoxy is overflowed onto the lens surface of the LED 12b, resulting in poor illuminance and light spreading.

In addition, the conventional LED lamp device (1) when the power supply line (2) is inserted into the lamp housing 11 is unevenly coupled to the left or right in the insertion path inside the center of the fastening of the conductive fastening member 13 is generated There is a disadvantage that the smooth power supply is impossible.

Conductive fastening member 130 to enable the supply of power to the module 120, and also formed in the lamp housing 110 and the guide hole (140a) formed on the same vertical axis line with the power supply line (2) The perforated guide member 140 and the power supply line 2 is further provided with an in-position retaining protrusion 160 to be in position on the same vertical axis line as the guide hole 140a.

The position maintaining protrusion 160 is configured to protrude on both sides of the supply line arrangement groove 115 so as to be in close contact with the power supply line 2, but protrudes in a substantially semi-cylindrical shape, but maintains a constant position of the power supply line 2. If possible, it can be configured in various shapes without limitation.

In addition, the amount of formation of the in-situ holding protrusions 160 may be decreased according to the length of the lamp housing 110 and the like, and the forming position thereof is not limited as long as the position of the power supply line 2 can be kept constant. Since the 130 and the power supply line 2 are fixed to each other in the guide member 140, it will be preferable to be disposed on both sides of the guide member.

In addition, the alignment retaining protrusion 160 is a more preferable configuration when the spacing (width) of the supply line arrangement groove 115 is formed to be slightly larger so that the insertion operation of the power supply line 2 can be easily performed. The spacing between the grooves 115 may be omitted when the gap between the grooves 115 does not differ significantly from the diameter of the power supply line 2.
