Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a vibration deduction device for an LED lamp,

The present invention relates to a vibration damping device such as a tunnel LED and more particularly to a vibration damping device provided with a vibration preventing means between a frame and an angle adjusting means to attenuate the transmission of vibration between a frame and an angle adjusting means and a mounting bracket, And to a vibration damping device such as a tunnel LED which can prevent a trouble of a tunnel LED and the like.

Conventionally, incandescent lamps, fluorescent lamps, and mercury lamps have been used for tunnels inside the tunnels. Recently, however, since the photovoltaic efficiency is high, the power consumption is low and the size, thickness and weight can be reduced. LED lamps are widely used because they are environmentally friendly because mercury used in fluorescent lamps and mercury lamps is not used and discharge gas is not used.

However, in the case of LED and the like, there is a problem that the luminous efficiency is lowered and the service life is shortened when the temperature rises. LEDs and the like have an operating temperature of -20 to 40 degrees centigrade.

As a prior art relating to a conventional tunnel LED, etc., Korean Patent No. 10-0876121 (registered on Dec. 19, 2008) "Tunnel using LED" (hereinafter referred to as " Prior Art 1 ") is embedded in a side wall of a tunnel A metal substrate having a plurality of LEDs mounted on a front surface of a cooling body is attached to a front surface of a frame body and a plurality of It is possible to easily install the light diffusion cover formed with the light diffusion portion and to reduce the contamination due to the soot, to allow the light to deviate from the view of the driver and to induce safe operation, and to use the LED as the light source, In order to reduce the cost of the system.

However, the prior art 1 has the following problems.

First, since the frame member is embedded in the sidewall of the tunnel, the irradiation direction of the light can not be controlled.

Second, a light diffusion cover for protecting the metal substrate and the LED from the front surface of the heat sink is coupled to the coupling curved surface portion formed at the upper and lower ends of the cooling body so that moisture and moisture penetrate between the cooling body and the light diffusion cover, There is a problem that the LED and the metal substrate are broken due to a short circuit due to moisture and moisture.

Thirdly, the front surface of the heat sink is blocked by the metal substrate and the light diffusion cover, and the cooling effect by the heat sink is not sufficiently exhibited because the rear surface of the heat sink, that is, the heat sink fin portion of the heat sink is close to the tunnel side wall surface. There is a problem that the light emitting performance is lowered and the service life is shortened as the operating temperature rises.

Fourth, since the heat sink is movably installed along the guide rail on the frame member, the metal substrate is coupled by the substrate joining guider (coupling protrusion), and the light diffusion cover is coupled over the upper and lower ends of the heat sink, The vibration is transmitted to the metal substrate and the LED through the frame member and the heat sink to cause the LED to be detached from the metal substrate or to cause the connection failure, and the light diffusion member is detached from the heat sink.

In addition, as a conventional prior art, Korean Patent Registration No. 10-1241972 (registered on March 31, 2013) "LED Tunnel and the like" (hereinafter referred to as "Prior Art 2") has an upper heat sink and a lower heat sink And a PCB module on which an LED chip is mounted is attached to the lower surface of the lower heat sink and a power supply unit (converter or the like) is mounted on the upper surface of the upper heat sink. So that the PCB module can be easily assembled.

However, the prior art 2 has the following problems.

First, it is disclosed that the heat dissipation performance is improved by attaching the PCB module having the LED chip mounted on the lower surface of the lower heat dissipation plate to the heat dissipation means. Since the PCB module is installed inside the case, the heat dissipation performance is lowered and the operating temperature of the LED chip is increased, so that the light emitting performance is deteriorated and the service life is shortened.

Secondly, since the PCB module on which the LED chip is mounted is simply protected by the protective cover, the waterproof performance is deteriorated, which causes the LED chip and the PCB module to fail due to moisture and moisture.

Third, the PCB module on which the LED chip is mounted is attached to the lower surface of the lower heat sink, and the protection cover is attached on the lower part of the PCB module. Since the LED chip is directly transferred to the PCB module on which the LED chip is mounted through the upper heat sink, the heat transfer member, and the lower heat sink, the LED chip may be detached or a connection failure may be caused.

As a conventional prior art, Korean Patent No. 10-1325538 (registered on October 30, 2013) "LED Tunnel Luminaire" (hereinafter referred to as "Prior Art 3") has a fixing body made of a metal material and a switching body, And a light transmitting plate and a reflection plate are coupled to the opening and closing body, wherein the reflection plate is formed with a light emitting diode (LED) light source, which is divided into the inside of the tunnel, And a heat radiating conductor having a plurality of heat radiating plates is coupled to the upper portion of the reflector plate so as to quickly diffuse heat generated from the LED light source plate into the inner space of the tunnel luminaire, And the heat conduction bracket to the whole of the tunnel luminaire made of metal material, The extension of the service life of the tunnel luminaire having a characteristic that maintains the light-on state, as well as it is possible to improve the light efficiency of the LED light source gailcheung plate, discloses a technique such that a very economical.

However, the prior art 3 has the following problems.

First, since the heat sink is embedded in the fixing body, heat generated from the LED is transmitted to the heat sink, and then the heat is dissipated to the outside through the fixing body. Therefore, the cooling effect is not sufficiently achieved, There is a problem that the light emitting performance is lowered and the service life is shortened.

Secondly, the light transmitting plate for covering the lower end opening of the fixing body is installed in a state in which the light transmitting plate covers the engaging jaw inside the lower end of the fixing body, so that moisture and moisture penetrate into the fixing body, thereby causing failure of the LED .

Third, an LED light source plate is attached to the lower end of a heat conduction bracket provided inside the fixing body, and a lower end opening portion of the fixing body is covered with a transparent plate. The vibration generated in the tunnel is transmitted through the fixed body, The LED is directly transferred to the board, and the LED is detached or the connection is bad.

In addition, as a conventional prior art, Korean Patent No. 10-1393509 entitled "LED Tunnel Luminaire" (hereinafter referred to as "Prior Art 4") accommodates SMPS in a length adjustable SMPS stand, So that the heat generated from the LED module, the PCB and the radiating fins can be escaped without affecting the SMPS, and the heat generated by the SMPS can be transmitted to the LED module and the PCB And the heat dissipation of the radiating fins is not influenced. Two or more rubber packings are stepwise inserted into the stepped joint structure so that airtightness inside the tunnel or the like is further improved. Waterproofing and dustproofing function can be performed faithfully.

However, the prior art 4 has the following problems.

First, a heat-radiating plate is installed inside a case made of an upper body and a lower body, an LED module is attached to a lower surface of the case, and the lower end opening of the case is covered with a lens and a globe, As a result, the operating temperature of the LED is increased and the light emitting performance is deteriorated and the service life is shortened.

Second, the glove for covering the lower end opening of the case is coupled in a state in which the glove covers the step portion formed inside the lower end of the case, and moisture and moisture enter into the case, causing the LED module to fail due to moisture and water have.

Third, the LED module is attached to the lower surface of the heat sink fixed to the inside of the case, and the lower end opening of the case is covered with the lens and the globe. The vibration generated in the tunnel is transmitted to the LED module through the case and the heat sink, There is a problem in that it is corrupted or connection failure occurs.

Therefore, it is possible to adjust the angle of the irradiation direction in the tunnel, improve the heat radiation performance and the cooling performance to lower the operation temperature of the LED chip, thereby improving the light emitting performance and extending the lifetime. It is desired to develop a technique for preventing breakdown due to moisture and water and for preventing vibration of the tunnel from dropping out or connection failure due to vibration.
