Description
The present invention relates to a lamp using an LED, and more particularly, to a lamp using a LED, more specifically, a heat-radiating member is forcedly pressed onto a mounting member without using a separate fastening member so that the heat- The present invention relates to a heat dissipation pin mounting apparatus for an LED lamp, which can mount a mounting member, which is made of an excellent metal material and integrated with a heat dissipating member, in a housing by a one-touch operation without using a separate fastening member.
Generally, an LED (light emitting diode) is an electronic component that produces a small number of injected carriers (electrons) using a p-n junction structure of a semiconductor and emits light by recombination of these minor carriers.
These LEDs are smaller in size and longer in life than conventional light sources (light sources), and have low power consumption and high efficiency because electric energy is directly converted into light energy.
In addition, since LED has characteristics of high-speed response, it is widely used for display lamps and numeric display devices of various electronic devices such as a display device of an automobile instrument, a light source for optical communication, and the like. It is applied variously as a lighting means for an evacuation lamp.
However, when a lamp using an LED is turned on, heat is generated by a component such as a resistor. If such a heat is applied to the LED, circuit characteristics are changed and the lifetime is shortened.
These LEDs are known to be easily damaged even when exposed to heat at about 70 ° C.
Therefore, when the lamp is constructed by using the LED, a heat sink (heat sink) is attached to the back surface of the circuit board on which the LED is mounted so as to quickly radiate heat to the outside, thereby shortening the lifetime of the LED by heat Minimizing.

However, the conventional apparatus having such a structure has the following problems.
First, as the size of the heat dissipating member varies according to the size of the lamp, a separate mold for molding the heat dissipating member has to be manufactured. Therefore, it is economically burdensome for a relatively small-sized lighting company.
Secondly, since the heat dissipating plate of the heat dissipating member is fixed to the substrate by the fastening member, not only the productivity is lowered but also the flatness of the heat dissipating plate produced by the casting is limited and the heat dissipating plate can not be closely contacted to the upper surface of the substrate The heat conduction performance is degraded.
Thirdly, since the cover is made of a transparent or translucent synthetic resin material, heat dissipation through the cover hardly occurs and the heat radiation efficiency is lowered, thereby shortening the lifetime of the LED.
Fourthly, as the cover is fixed to the substrate by screwing, the screw is exposed to the outside, resulting in deterioration of appearance and lowering of productivity due to fastening of the screw.
SUMMARY OF THE INVENTION The present invention has been made in order to solve the above problems, and it is an object of the present invention to provide a heat dissipating member, a heat dissipating member, And the member is mounted on the metal housing in a one-touch manner, thereby improving the productivity of the lamp and maximizing the heat dissipation efficiency.

According to an aspect of the present invention for achieving the above object, there is provided an apparatus for mounting a heat dissipation pin of an LED lamp in which a groove is formed in a mounting member to which an LED is fixed and a heat dissipating member is fitted in the groove, Wherein the heat dissipating member is pressed and fixed to the mounting member in a state where one side of the heat dissipating member is aligned with the compression groove and the side surface of the mounting member is protruded obliquely A protruding piece having a latching groove is formed on the inner surface of the housing made of a metal material and the latching protrusion projecting obliquely is engaged with the latching groove of the protruding piece by rotating the fitting member with the housing, The heat dissipation fin mounting device of the LED lamp is provided.
Wherein the mounting member, the heat dissipating member, and the housing are made of aluminum or copper.

The present invention has the following advantages over the conventional apparatuses.
First, the mounting member has the same compression groove as the end face of the heat dissipating member, so that it is possible to press and fix the contact area of the mounting member without using a separate fastening member to maximize the contact area. Therefore, It is possible to radiate heat.

Secondly, since the housing is made of an aluminum material, heat is radiated simultaneously through the housing as well as the heat dissipating member, thereby maximizing the heat radiation efficiency, thereby extending the lifetime of the LED to the maximum extent.
Thirdly, if the mounting member having the heat dissipating member fixed thereto is pivoted and then rotated, the locking protrusion formed opposite to the outer circumferential surface of the mounting member is hooked on the locking groove formed in the inside of the housing to complete the mounting, Thus, not only the assembling property can be improved but also the appearance can be improved.
