The present invention relates to an LED fluorescent lamp apparatus, and more particularly, an LED fluorescent lamp in which a bonding force between a housing (H) containing a substrate and a sealing cap (C) sealing the housing (H) is increased, and power connection stability is improved. It's about instruments.

As shown in FIG. 1, the LED fluorescent lamp apparatus according to the present invention is coupled to a substrate including an LED, a first housing H1 in which the substrate is embedded, and an upper portion of the first housing H1 and has an arch shape. It includes a second housing (H2), and a sealing cap (C) for sealing the front and rear sides of the first housing (H1) and the second housing (H2).

First, looking at the substrate including the LED, as shown in FIG. 4, the substrate is inserted into the substrate groove H12 and coupled thereto. The substrate groove H12 is formed inside the first housing H1.

And, as shown in FIG. 4 , the substrate groove H12 can employ an injection-molded product having high insulation properties, and has an advantage in that it has high insulation properties and mass production is possible. And here, the raw material of the injection molding means plastic resin.

Next, the first housing (H1) is composed of a 'c'-shaped tubular structure, and on the outer side of the upper portion, a binding groove (H11) to which the second housing (H2) is coupled, and on the inner side of the upper portion, the above-described substrate groove. (H12) is formed.

Looking more specifically, the binding support surface includes an inner binding support surface H13a formed on the inner side of the second housing H2 and an outer binding support surface H13b formed on the outer side of the second housing H2. However, in the case of the inner binding support surface (H13a), when an external force acting in the inward direction exists, the first housing (H1) and the second housing (H2) are not separated and contribute to maintaining the binding force. And, in the case of the outer binding support surface (H13b), when an external force acting in an outward direction exists, the first housing (H1) and the second housing (H2) are not separated and contribute to maintaining the binding force. do.

In addition, the first housing (H1) includes an upper binding member (H14) connected inwardly from the inner binding support surface (H13a) and formed inclinedly, and a lower binding member (H14) connected inwardly from the outer binding support surface (H13b). (H15).

The upper binding member H14 blocks the upper portions of the binding groove H11 and the substrate groove H12, and supports the upper side of the substrate and the binding band H21 that are bound and inserted into each. Similarly, the lower binding member H15 blocks the bottom of the binding groove H11 and the substrate groove H12, and supports the lower side of the substrate and the binding band H21 that are bound and inserted into each.

A characteristic point is that, as shown in FIG. 4, the upper binding member H14 is formed inclined, and strong sealing can be secured according to the increase in contact area with the sealing cap C, which will be described later.

Further, the first housing H1 includes reinforcing protrusions H16 protruding outward from both ends of the bottom surface H17. The reinforcing protrusion H16 increases the contact force with the sealing cap C, which will be described later, to ensure strong sealing.

In addition, a fin pattern H18 having a fin shape is formed on the outer surface of the first housing H1, which helps workers to stably grip during maintenance and repair, and the first housing H1 The material of is preferably composed of a metal material containing aluminum.

In addition, the binding band H21 of the second housing H2 has a cylindrical shape, and the end of the binding band H21 formed on the end side of the binding band H21 is the inner binding support surface ( H13a) and the outer binding support surface H13b form an angle of 45 degrees, respectively. In addition, by forming an angle of 45 degrees as described above, it is possible to stably maintain the bonding force against both the external force acting inward and the external force acting outward.

Next, let's take a look at the sealing cap (C). 2 and 3, the sealing cap (C) includes a 'c'-shaped sealing reinforcement member (C12) protruding inward from the inner surface of the sealing cap (C), and the sealing reinforcement The member (C12) includes a wall member (C121) provided symmetrically on both sides and a base member (C122) connecting the lower end of the wall member (C121).

Also, the protruding length of the wall member C121 inward is at least three times longer than the width of the main body C1, which is to enhance sealing with the housing H.

And the sealing cap (C) includes a receiving member (C13) including a receiving space for accommodating the connection member between the wall member (C121), the receiving member (C13) is the sealing cap (C) A partition wall C131 protrudes to the inside of the partition wall C131 and a mounting member C132 protrudes from the lower end of the partition wall C131 toward the receiving space. And, the connection member is seated on the upper portion of the seating member C132.

In addition, the partition wall C131 includes the central partition walls C131b and C131 provided at the center of the accommodating member C13 and the side partition walls C131a and C131 provided at the sides of the center partition walls C131b and C131. include In addition, a seating member C132 is formed by protruding from both lower ends of the central partition walls C131b and C131 toward the accommodation space, and a seating member extends from one lower end of the side partition walls C131a and C131 toward the accommodation space. (C132) is formed by protruding.

In addition, the sealing cap (C) forms a body (C1) in the center based on the direction of covering or removing the sealing cap (C), and the direction of subtracting the sealing cap (C) based on the body (C1) ( An outer bracket (C11) formed on the outer side) and a sealing reinforcement member (C12) formed on the covering direction (inner side) are formed.

The body C1 is composed of a first body C1a in contact with the first housing H1 and a second body C1b in contact with the second housing H2.

And, as shown in FIG. 3, a predetermined space exists between the body C1 of the sealing cap C and the wall member C121, and the first housing H1 is inserted into the predetermined space. Thus, the first housing H1 can be sealed.

And the second body (C1b) includes a second main body fixing portion (C14) formed to protrude inwardly and have an arch shape on the inner surface. In addition, the second housing H2 can be fixed to a predetermined space between the second main body fixing part C14 and the second main body C1b.

Next, the sealing cap (C) protrudes outward from the outer surface of the sealing cap (C) and includes a connection guide member (C2) having a fork shape, and is seated on the top of the connection guide member (C2). , The connection guide member (C2) includes a connection cover (C3) coupled to the coupling groove (C24) formed on the inner surface.

The connection guide member (C2) includes three vertical guide projections (C21) protruding outward and arranged side by side with each other, and a horizontal guide projection (C22) formed by extending from the vertical guide projections (C21) toward the connection guide hole. .

In addition, the vertical guide protrusion C21 includes a central vertical guide protrusion C21b provided at the center of the connection guide member C2 and a side vertical guide protrusion C21a provided on the side of the central vertical guide protrusion C21b. includes

The horizontal guide protrusion C22 includes an upper horizontal guide protrusion C22a formed on an upper portion of the vertical guide protrusion C21 and a lower horizontal guide protrusion C22b formed on a lower portion of the vertical guide protrusion C21.

Further, the lower horizontal guide projections C22b are formed extending from both sides of the lower end of the central vertical guide projection C21b toward the connection guide.

And the lower horizontal guide protrusion (C22b) is formed extending from one side of the lower end of the side vertical guide protrusion (C21a) toward the connection guide hole.

In addition, the upper horizontal guide protrusion C22a extends from one side of the upper end of the side vertical guide protrusion C21a toward the connection guide, and the protrusion is smaller than that of the lower horizontal guide protrusion C22b.

And the side vertical guide protrusion (C21a) includes a stepped portion (C23) on the upper portion. The stepped portion C23 corresponds to a configuration provided to make the size of the main coupling groove C24a larger than that of the sub coupling groove C24b, which will be described later.

Prior to explaining this, first, the inner surface of the connection cover C3 includes a coupling protrusion inserted into the coupling groove C24, and the coupling protrusion is formed on the inside and has a cylindrical shape and is larger than the main protrusion. It is formed on the outside and includes a sub-protrusion having a rectangular parallelepiped shape. And the connection guide member (C2) includes a main coupling groove (C24a) and a sub coupling groove (C24b) at positions corresponding to these main projections and sub projections, respectively.

In this way, the main protrusion is inserted into the main coupling groove (C24a) and the sub-protrusion is inserted into the sub coupling groove (C24b) at different positions, thereby creating a gap between the connection guide member (C2) and the connection cover (C3) according to the dispersion of the coupling position. A stable bonding force can be realized. And, as described above, the main protrusion is configured to have a cylindrical shape, and the sub-protrusion is configured to have a rectangular parallelepiped shape so as to have a different shape, thereby maximizing the stability of the aforementioned bonding force.

In addition, the volume of the main protrusion is larger than that of the sub-protrusion, and correspondingly, the size of the main coupling groove C24a is larger than that of the sub coupling groove C24b.

And the reason why the main protrusion is configured in a cylindrical shape is that when a larger external force acts, the force can act in the direction in which the connection guide member C2 and the connection cover C3 are separated. This is because a larger force acts on the projection side, so damage may occur if the angle is configured as a regular rectangular parallelepiped.

In addition, the reason why the sub-projection is formed in the shape of a rectangular parallelepiped is to distribute the aforementioned external force in the horizontal/vertical direction through a horizontal/vertical structure (each side of the rectangular parallelepiped forms a structure at right angles to each other).

Here, distributing the external force in the horizontal/vertical direction means that the horizontal/vertical components of the external force do not randomly reach the sub-protrusions and sub-coupling grooves C24b, but in places where the horizontal component of the external force is dominant through an angular structure, it It means that it predominantly shares it in the vertical plane and, where the vertical component of the external force is dominant, it most predominantly shares it in the plane perpendicular to it.

And the connection cover (C3) includes an upper cover (C31) constituting the upper surface, a front cover (C32) covering the front side of the connection guide member (C2) and a side cover (C33) covering the side side. The characteristic point here is that the length of the upper cover (C31) protrudes toward the front side to guide the connection is formed longer than the length of the connection guide member (C2), so that the front cover (C32) is the connection guide member ( The front surface of the connection guide member (C2) is covered at a spaced distance from the end of C2). In order to supplement the rigidity of the side surface of the connection cover C3 by the spaced distance, the side cover C33 is configured to cover the side surface.

And as shown in Figure 5, it can be seen that the front cover (C32) is provided with an inlet groove (C321) for wire entry, and the upper side of the inlet groove (C321) is formed round to have an arch shape. there is.

Next, as shown in FIG. 6, it can be confirmed that a rectifier circuit and a smoothing circuit are configured before the plurality of LEDs, and a resistance unit is configured after the plurality of LEDs.

In the case of the rectifier circuit and the smoothing circuit, it is provided to align the direction of the current flowing into the plurality of LEDs in one direction, and in the case of the resistance part, safety accidents such as explosion due to overcurrent when one or more of the plurality of LEDs are shorted It is provided to prevent. Here, as an example, in the case of the resistor unit, R-0805 products (resistors to which surface mounting technology is applied) can be used.

A chip varistor may be provided between the power supply terminal and the rectifier circuit, and TVB7S471KR may be used as an example of the chip varistor.
