Description

  The present invention relates to an LED bulb, in particular, by using a convex seat added to the base, and by sticking the LED module to the convex seat with heat dissipation tape, increasing the assembly speed of the LED bulb and increasing the production rate, Furthermore, the illumination angle of the LED bulb is increased, the illumination range of the LED bulb is expanded, and the convex seat is integrally formed with the base so that the heat radiation efficiency is taken into consideration.

  As LED technology advances day by day, LEDs are divided into different light emitting structures such as OLEDs, PLEDs, etc., so that LEDs can be used more versatilely and universally for applications such as lighting and flat display interfaces. The volume of the LED lamp used for illumination is small and the wattage consumed is relatively low, and the efficiency (lumen / watt) of the LED is the highest compared with the incandescent bulb and the energy saving bulb. For example, the efficiency of an incandescent bulb is about 15%, the lifetime is about 1000 hours, the efficiency of an energy saving bulb is about 65%, the lifetime is about 10,000 hours, and the efficiency of a cold white LED is about 75-80%. The lifetime is about 40,000 hours. That is, the LED has the lowest power consumption and the highest luminous efficiency, its service life is relatively long, and it is most consistent with the concept of environmental protection, so that the LED is universally used in flashlights and lighting fixtures. It is done.

  Please refer to FIG. In a known LED bulb, a housing 201 is provided at one end of the conductive portion 101, the housing 201 includes a space 2011 therein, and a plurality of LED light emitting elements are mounted and fixed in the housing 201 internal space 2011. Finally, a semicircular lamp cover 301 is fitted into the housing 201 to form an LED bulb.

  The light emitted from the LED belongs to direct light, and its irradiation angle is about 20 degrees. When used for wide-angle illumination, the illumination effect is far less than incandescent bulbs and energy-saving bulbs. For example, during wide-angle illumination, a 100 watt incandescent bulb can achieve an average of 1300 lumens, and a 20 watt energy saving bulb can achieve approximately 1000 to 1200 lumens. On the other hand, 8-watt LED bulbs average 500-600 lumens, because LEDs are limited to overcoming heat dissipation technology, so the quantity of relatively high wattage LEDs is rare and the price is very high Become.

  Further, if an LED bulb having a known structure is attached, the irradiation range is as shown in FIG. 1, which is disadvantageous for indoor lighting, and when the LED light emitting element is mounted in the internal space 2011, the casing 201 is Occupies a light emission range close to 1/2 of the LED light-emitting element, and thus the irradiation angle is limited to the semicircular lamp cover, which greatly reduces the efficiency of the LED bulb, and the light emission range also extends to incandescent and energy-saving bulbs. Disappear.

  For this reason, general consumers are not motivated to purchase because the indoor lighting effect is low. For this reason, when used for indoor lighting, it is not easy for LED bulbs to replace incandescent bulbs and energy-saving bulbs, and environmentally friendly LED bulbs are not easily promoted.

  Furthermore, a well-known LED bulb is assembled as a bulb by a method in which the base and the LED light-emitting element are separately manufactured and then mounted and fixed, but such an assembly method takes time and increases the production speed of the LED bulb. Reduce.

Taken together, known LED bulbs have some problems to overcome:
1. A plurality of LED light emitting elements are mounted and fixed in the internal space of the base, the light emission range is a slightly semicircular lamp cover, and the irradiation angle of the LED bulb is extremely narrow.
2. After the base and the LED light emitting element are manufactured separately, they are assembled as a light bulb by a mounting and fixing method. This assembly method is time consuming and reduces the production speed of the LED bulb.

The seat is formed integrally with the base so that the heat dissipation efficiency of the LED bulb is taken into consideration.

  The LED bulb according to the present invention includes an adapter plug provided at one end with a conductive portion attached to a coupling portion of the bulb, and provided with a connecting member having a plurality of connecting portions at one end opposite to the conductive portion, A connecting portion corresponding to the connecting member is provided and can be coupled to the adapter plug, and a base provided with a convex seat at one end opposite to the connecting portion, and installed corresponding to the surface of the convex seat, And a plurality of LED modules forming an electrical connection with the adapter plug, and a lamp cover corresponding to the base and coupled to the base.

  In the LED bulb described above, the LED module is attached to the convex seat with a heat dissipation tape.

The LED bulb described above is further provided with a driver, which is housed in the internal space and forms an electrical connection with the LED module and the adapter plug.

  With the installation described above, the LED module is attached to the convex seat with heat dissipation tape, increasing the assembly speed of the LED bulb, thereby increasing the production rate, and further increasing the irradiation angle of the LED into a three-dimensional shape of the convex seat. Along with this, the illumination range of the LED bulb is expanded, and the LED bulb is expanded with the integrated design of the convex seat and the base, and the heat dissipation efficiency is taken into consideration.

The adapter plug 2 and the base 3, which can be attached to a socket, provided with a connecting portion 22 at one end opposite to the conductive portion 21, and provided with a plurality of connecting members 221 at the connecting portion 22, It is a heat-dissipating aluminum sheet, and is provided with a connecting portion 31 corresponding to the connecting member 221 at one end. In this embodiment, the connecting member 221 is a single body that is used for locking. The base 3 is connectable to the adapter plug 2 by the concave groove corresponding to the one body, and an integrally formed convex seat 32 is formed at one end of the base 3 opposite to the connecting portion 31. Established The convex seat 32 is a polygonal column or a polygonal pyramid. In the illustrated embodiment, the convex seat 32 is a quadrangular column, and an internal space 321 is provided in the convex seat 32. The housing space of the base 3 is increased.
