Description

LED street light and PCB manufacturing method that have a protection cap}

The present invention relates to a method of manufacturing a LED lamp equipped with a street lamp and a protective cap using an LED. More specifically, the LED lamp is manufactured to manufacture a street lamp having a low manufacturing cost by improving its function as a street lamp by effective efficiency. It relates to a manufacturing method of the PCB and the street lamp and the protective cap is mounted.

Street lamps are literally installed on the streets to illuminate for safety and security. Various types of street lamps are used depending on the installation location such as highways, main roads in the city, commercial roads, and residential district roads.

At this time, the type of the street lamp is a highway type (flexible) that bends the end of the pole according to the type of the pole that is equipped with the lighting, that is, the lamp extends horizontally at the end of the pole and hangs there. The main features are bracket type and head type with the back of the pole.

In addition, mercury lamps have been used as light sources in the past, but various types of light sources such as fluorescent lamps and sodium lamps have been selectively used according to the situation. Recently, LEDs are used as light sources to obtain low power and high brightness. Doing.

Figure 6 is a bottom perspective view showing a conventional LED street light, Figure 7 is a conceptual view showing a conventional one-LED street light, the LED (2; LED) is mounted on the bottom of the lamp 1 is installed in a number of constant arrangement. PCB (3; PCB) is mounted, and the protective cover (4) for the function of the light-transmitting lens while covering the whole of the PC (3) is mounted.

The protective cover 4 is formed so that the light of the LED 2 can be effectively irradiated to the desired part while protecting the PC 3 sensitive to moisture.

However, light emitted from one LED 2 is irradiated over the entire bottom surface, and when a plurality of such LEDs 2 are combined, the direction of light passing through any part of the protective cover 4 cannot be determined. It will be irradiated at various angles.

In this case, when light is irradiated in a direction perpendicular to the surface of the protective cover 4, most of the light is transmitted. However, as the inclination angle increases, some of the light is refracted and some of the light is particularly reflected when the light is reflected. Is due to the light that does not pass through the protective cover 4 is to cause a sharp drop in efficiency.

In order to solve this problem, a method of manufacturing a cover in which a lens part arranged corresponding to each LED is formed through a mold mold at a time was used. However, the investment cost for the initial equipment is very expensive and many lenses are formed in one cover. Due to many variables such as bubbles, unfilled, and discoloration, the defect rate is high, which is also a cause of unit price increase.

In addition, this method has to produce a mold again when the arrangement of the lens changes, there is a problem in that it is difficult to apply a variety of lenses to one cover.

In addition, it is to develop a manufacturing method of a PC with a street lamp and a protective cap using the LED to enable the manufacturer to arbitrarily adjust the direction in which the light of each LED is easily adjusted to obtain the most optimal lighting effect.

In addition, it is to develop a manufacturing method of the PC with a street lamp and a protective cap using the LED is equipped with a protective cap on each LED to increase the efficiency of the light and to facilitate its manufacture.

The present invention has been developed to achieve the above object, using a plurality of LEDs (LED) is mounted on the bottom of the PCB (PCB) is mounted using a protective cover for inducing the direction of the light while protecting it In a street lamp;

The street light is formed with a heat sink is formed on the bottom surface of the PCB insertion groove, the plurality of LEDs are arranged on the bottom of the LED be inserted into the PC insertion groove;

Each of the LEDs is equipped with a protective cap to perform the role of the lens at the same time, to form a layer on the bottom of the PCB other than the portion mounted with the protective cap to secure the protective cap, the waterproofing and It is characterized in that the epoxy molding layer for further heat dissipation.

In addition, at least two or more PCB insertion grooves are formed on the bottom of the heat sink by a partition wall protruding from the bottom surface therebetween;

Each of the PC insertion groove is characterized in that the PC is mounted with a corresponding LED is inserted.

In addition, the protective cap is mounted on the LED is mounted on the central portion of the bottom surface of the street light having a first lens having an omnidirectional lens for irradiating light in all directions, the outer portion irradiates light only in the outward direction of the center It characterized in that the second lens is mounted.

In addition, in the manufacturing method of the PC with a protective cap equipped with a plurality of LEDs and a protective cap equipped with a protective cap for each LED to serve as a function of the lens;

A protective cap mounting process for attaching a protective cap having a desired function to each LED in the PCs having a plurality of LEDs arranged on an upper surface thereof;

A die mounting process of inserting the PCB with the protection cap into a formwork having a PCB inserting portion formed on a top surface of the PCB to form an outline;

An epoxy molding process of forming an epoxy molding layer to form a layer on a surface on which the LEDs and the protection cap of the PC are mounted to a predetermined thickness, and to fix the protection cap and to waterproof and dissipate the PC from the outside;

Characterized in that the series of the process of separating the PCB to separate the formwork and the PCB.

As described above, the present invention allows the light source of the LED to be irradiated without being lost by diffuse reflection or the like, thereby optimizing the light efficiency of the street light.

In addition, there is an effect that the manufacturer can easily adjust the direction in which the light of each LED is easily obtained to obtain the most optimal lighting effect.

In addition, by mounting a separate protective cap to the LED to easily fix it has the effect of easy manufacturing.

Accordingly, the configuration of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art can easily understand and reproduce.

1 is a bottom perspective view according to an embodiment of the present invention, Figure 2 is a conceptual view according to an embodiment of the present invention, a plurality of LEDs (2; LED) is mounted on the bottom (3; PCB) is mounted In the street light (1) using the LED consisting of a protective cover 4 for inducing the direction of the light while protecting it;

A heat dissipation plate 5 is formed on the bottom of the streetlight 1 to form a PCB insertion groove 51, and the PC 2 having the LEDs 2 arranged on the bottom thereof is mounted on the PC insertion groove 51. Being;

Each of the LEDs 2 is equipped with a protective cap 21 for simultaneously performing the role of a lens, and forming a layer on the bottom surface of the PC 3 except for the portion on which the protective cap 21 is mounted. Fixing the cap 21, the street lamp using the LED characterized in that the epoxy molding layer 22 is further formed to waterproof and dissipate the PC 3 from the outside.

The biggest feature of the present application is that the protective cap 21 is manufactured in the form of each small cap without fabricating the form of one protective cover arranged in a plurality of assembled and then fixed it by the epoxy molding layer 22 I did it.

In this case, a single protective cap 21 is mounted on a single light source, that is, the LED 2, thereby minimizing the ratio of diffuse reflection to the light source without passing through the protective cap, thereby increasing light efficiency.
