Description

  The present invention relates to an improvement in the structure of an LED lamp using a light emitting diode as a light source.

   A lamp using a light-emitting diode as a light source uses a block-shaped metal radiator that is excellent in heat conduction, an LED (infrared) chip is embedded above the radiator, and the chip has a planar shape (for heat radiation), Alternatively, it has a concave shape (for condensing). The LED chip generates heat energy and quickly absorbs it by the radiator, thereby lowering the temperature of the LED chip, and further, the heat absorbed by the radiator is a metal heat conduction base made of copper or aluminum. Conducted upward, the temperature of the radiator and the LED chip is lowered, and the heat conduction base conducts thermal energy to the radiator, and further, the thermal energy of the radiator is diffused into the atmosphere.

   On the other hand, the lamp cover is made of an aluminum alloy material, the inner edge of the lamp cover has a smooth parabolic arch shape, and the light flux of the light emitting diode is concentratedly reflected by different diffusion angles, and the lamp cover and the heat conduction base are combined. As a result, the outer shell serves as a fixing and protection role, and directly absorbs the heat energy of the heat conduction base, so that the overall structure is a structure of an LED lamp that is strong in heat resistance and impact resistance.

  As shown in FIG. 1, the structure of a conventional LED lamp 1 includes an outer shell 11, a lens 12, an LED 13, and an outer cover 14, and the LED 13 is disposed at the outer peripheral edge of the lens 12. Is arranged inside the outer shell 11, and the upper edge of the outer shell 11 is covered with an outer cover 14.

  The structure of the LED lamp 1 is that the lens 12 occupies most of the space, is expensive, and the energy of the luminous flux emitted from the LED 13 is limited, the range illuminated by the luminous flux is small, and the distance is short.

  The structure of the conventional LED lamp described above requires a large number of light emitting diodes, and increases in volume and width. When many light-emitting diodes are lit for a long time, the thermal energy becomes very high, and for example when installed in a sealed surveillance camera, the light-emitting chip burns out quickly and the transparency of the light-emitting diodes is mist. The service life of light emitting diodes will be shortened.

  Next, the disadvantages of the conventional structure are listed below.

  1. A conventional light source is located on the outer periphery of the lens, and requires a large number of light emitting diodes to supplement the light source required by the lens, and requires a large volume.

  2. If the number of light emitting diodes is large, the thermal energy becomes very high when used for a long time, and if installed in a sealed surveillance camera, the LED chip will burn out quickly due to high heat and the light emitting diodes will be transparent The package is misted and the lifetime of the light emitting diode is short.

  3. Since the chip of the light emitting diode is packaged by a transparent package body, and the thermal energy emitted from the chip is only dissipated by the metal support, the brightness of the chip and the current are in a direct proportional relationship. The amount of current required is limited.

  The present invention has been made in view of the above points, and an object of the present invention is to provide an LED lamp structure that has a long service life of a light-emitting diode, a small lamp volume, and can quickly dissipate heat.

  In order to achieve the above object, the structure of the LED lamp according to the present invention is made of gold, silver, copper, aluminum, etc., in which an LED chip is formed, in which a flat surface or a concave surface is formed on one surface and another surface is disposed in an insulating frame. The metal heat sink and female screws of different sizes at both ends, one female screw is screwed into the male screw formed on the outer shell of the LED bottom, and the other female screw is screwed into the male screw of the lamp cover. And a metal heat dissipating body disposed on the plane of the front end of the female screw, a heat conducting base made of copper that absorbs and diffuses heat energy absorbed by the metal heat dissipating body, and a frame. And having an insulating frame having one end disposed on the front end plane of the heat conducting base, and sandwiching and fixing the heat dissipating member at a predetermined position.

  According to the present invention, the following effects can be achieved.

1. By collecting several heat radiators on one heat conduction base, the light sources gather together to form a light beam, and only one light emitting structure can be used as a light source required by a surveillance camera, for example. Can be saved.

2. The heat energy emitted from the LED chip can be quickly released into the atmosphere via a radiator, heat conduction base, radiator, and lamp cover, and can be quickly dissipated, resulting in a long lamp life and LED lamp. The volume of can be reduced.

3. The heat energy of the LED chip is quickly dissipated, and the outer periphery of the LED chip is not packaged, and the LED chip can receive a larger amount of current, which can increase the brightness of the LED chip and the efficiency of the light source. .
