Description

A BULB TYPE LED LAMP

The present invention relates to an LED lamp, and more particularly, to an LED lamp that simplifies a product and minimizes the number of components, thereby improving productivity and reducing product cost, The present invention relates to a spherical LED lamp.

Generally, as a lamp for illumination, a fluorescent lamp is used in which a fluorescent substance is applied between an incandescent lamp and the like, in which a filament is emitted by a discharge of an electrode, and a fluorescent substance is emitted by a discharge of the electrode.

In the case of the incandescent lamp, there is a disadvantage in that it is close to natural light but has a large power consumption. In the case of a fluorescent lamp, the power consumption is relatively less than that of an incandescent lamp, but there is a drawback that power consumption is considerable. There was a disadvantage that the lifetime was not long.

In recent years, LED lamps that use LED devices as light sources instead of such incandescent lamps and fluorescent lamps have been rapidly used due to their long life and low power consumption.

In addition, among the LED lamps, a bulb-type LED lamp which can be used as a conventional incandescent lamp by being screwed into a socket like a conventional incandescent lamp has been developed and used.

However, the conventional bulb-type LED lamp has the following problems.

Since the conventional bulb-type LED lamp has a separate body for providing components such as a rectifier, a transformer, and the like, and a heat sink for discharging the heat generated from the LED to the outside, the number of parts is increased, There is a problem that the productivity of the product is lowered and the cost is increased.

Further, since a separate structure for mounting a heat dissipating member for dissipating heat generated from the LED has to be adopted, there has been a problem that the number of parts and the number of assembling holes of the LED lamp itself increase.

SUMMARY OF THE INVENTION Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art, and it is an object of the present invention to provide a bulb-

First, it simplifies the product, minimizes the number of parts,

Second, since the casing itself serves as a heat sink, there is no need to employ a separate heat sink, so that it is possible to reduce the number of parts and assembling airflow,

Third, by manufacturing the casing for combined use of heat sink by press working, it is possible to manufacture the combined casing for heat sink in only one step, thereby shortening the manufacturing time of the product and saving the manufacturing cost,

Fourth, the mounting plate is brought into face-to-face contact with the casing so as to increase the thermal conductivity by surface contact,

Fifth, since the mounting plate can be fastened only by inserting and inserting the mounting plate into the casing without a separate fastening means, it is possible to improve assembling workability, realizing assembly workability and cost reduction,

Sixth, the protruding pattern and the recessed pattern are repeatedly formed in the casing for the heat sink, thereby increasing the surface area and increasing the heat radiation efficiency.

Seventh, by forming the casing for the heat sink having the protruding pattern and the concave pattern formed by press working, it is possible to simultaneously manufacture the casing and the protruding pattern and the concave pattern serving as the heat sink by one press working, thereby increasing the productivity and reducing the cost ,

Eighthly, it is an object of the present invention to provide a bulb-type LED lamp which is suitable for simple, fast, and solid fastening of a light-transmitting cover.

In order to achieve the above object, the present invention provides a spherical LED lamp comprising: a screw-type socket connection part which is installed in a fixture such as a ceiling, a wall or a column and is screw-connected to a screw-type socket connected to a commercial AC power source; A casing coupled to the screw-type socket connecting portion and having a tubular shape so as to have an LED substrate therein, the casing being formed of a metal so as to dissipate heat of the LED substrate; A mounting plate provided in contact with the interior of the heat sink combined casing and transmitting heat generated from the LED substrate to the casing serving as the heat sink; An LED substrate mounted with an LED module composed of LEDs, electrically connected to the threaded socket connection portion by electric wires, and mounted on a lower surface of the mounting plate; And a light-transmitting cover which surrounds the LED substrate and is fastened to the lower end of the heat-and-smoke casing.

The bulb-type LED lamp having the above-described configuration has the following effects.

First, there is an effect that the thermal efficiency can be increased while minimizing the number of components by simplifying the product.

Second, since the casing itself serves as a heat sink, there is no need to employ a separate heat sink, and therefore, the number of parts and the number of assembling steps can be reduced, thereby reducing the cost.

Third, by manufacturing a casing for combined use with a heat sink, it is possible to manufacture a combined casing for a heat sink in a single process, thereby shortening the manufacturing time and manufacturing cost of the product.

Fourth, the mounting plate is brought into face-to-face contact with the casing so as to increase the thermal conductivity by surface contact, thereby increasing the heat radiation efficiency.

Fifth, the mounting plate can be fastened only by inserting and inserting the mounting plate into the casing without a separate fastening means, thereby improving assembling workability and realizing an assembly workability and a cost reduction.

Sixth, the protruding pattern and the recessed pattern are repeatedly formed in the casing for the heat sink, so that the surface area is widened and the heat radiation efficiency can be increased.

Seventh, by forming the casing for the heat sink with the protruding pattern and the concave pattern formed by press working, it is possible to simultaneously manufacture the heat sink combined casing and the protruding pattern and the concave pattern by one press working, thereby increasing the productivity and reducing the cost .

Eighth, there is an effect that the light projecting cover can be fastened simply, quickly, and firmly.
