Description

Improved structure of LED light bulbs

technical field

The utility model relates to the structure of an LED light bulb, in particular to an improved structure of an LED light bulb with an internal electrothermal separation design, which has a good heat dissipation effect and can effectively increase the area.

Background technique

Since humans discovered fire, there is light in darkness, and life has progressed and become more and more civilized. From early campfires to elegant lanterns, until Edison invented lamps in modern times, lamps have been replaced and improved several times. Lamps are no longer limited to simple lighting. The diversification of its shape and the improvement of various switching functions make the change of lighting more vitality, and it has become an indispensable main element of lighting and space shape changes.

The life of the LED in the new generation of light-emitting components is at least 10 years longer than the current lighting system, and the power consumption is lower. In addition, the LED does not contain mercury and is harmless to the environment. It has become the best lighting source in the future and has great potential. Development value, under the active development of the industry, various new LED bulb structures have been successfully designed and patented.

For example, in the published patent case TW 427477, the creation relates to a LED light bulb structure for a warning light, which mainly includes a combined lampshade, and a circuit board with an LED bulb is assembled in the middle section of the lampshade, and placed on the lampshade. A conical reflector is embedded in the top edge of the interior, so as to refract the light projected upward by the LED bulb horizontally and project it on the outer shell of the warning light. In addition, there is a lamp holder at the bottom of the lampshade, and a lamp holder is provided on the periphery of the lamp holder. , so as to be clamped on the lamp holder inside the warning lamp.

However, no matter how its appearance is changed, as the brightness increases, the LED bulb will generate heat when it is used, which is enough to affect its service life. This is not big, so the heat dissipation effect it can achieve is quite limited, which is its biggest shortcoming.

In view of the existing shortcomings of the above-mentioned traditional LED light bulbs, the utility model finally successfully developed the utility model after researching, improving and designing in many ways.

Contents of the invention

The purpose of the utility model is to provide an improved structure of the LED light bulb to overcome the above-mentioned defects of the traditional structure, and to effectively increase the area with good heat dissipation effect through the structural design of the electric-heat separation inside.

In order to achieve the above-mentioned purpose, the improved structure of an LED light bulb designed by the utility model is provided with a light bulb head on the outside, and a light-emitting diode LED as a light source is arranged inside, and the feature is that the inside of the light bulb is separated by electric heat It is composed of LEDs, and the middle of the LED base is provided with a table top for placing light-emitting crystals, and power pins are protruded on both sides, and an enlarged heat sink with an area larger than the bottom area of the base is pasted on the bottom of the base.

Wherein, the base of the electrothermal separation LED is an elliptical block with a trumpet-shaped opening in the middle, and the above-mentioned light-emitting crystal table is arranged inside. Then fill it with a light-transmitting adhesive layer; and the enlarged heat sink is an elliptical metal sheet body, and its two long sides protrude and are perpendicular to the aforementioned pins; and the enlarged heat sink is arranged in the opening below the bulb head , and its LED pins have wires connected to the bulb head.

Wherein, a control circuit board is added inside the LED light bulb.

Wherein, a light-transmitting lampshade is additionally provided in front of the bulb head of the LED bulb.

The beneficial effect of the utility model: through the above-mentioned structure, the formed LED light bulb can effectively improve the heat dissipation effect because of the internally preset enlarged heat sinks separated by electric heat.

In order to enable a further understanding of the composition and other features of the present utility model, a more specific embodiment of the present utility model is given hereby, and the detailed description of the embodiment in conjunction with the accompanying drawings is as follows.
