New description: [New technical field] This creation involves an improved structure of a light bulb using LED as a light source. [Prior Art] The basic structure of the commercially available power-saving light bulb is that a layer of phosphor powder (Phosphor) is coated on the surface of the lamp, and argon gas (Wrg〇n) and helium gas (N rhyme) are filled inside the lamp tube, and There are mercury pipes scattered throughout. The mercury vapor in the _t sub-ship light tube produces plasma (Plasma) and emits short-wave ultraviolet light (U1 Shi a-Violet) 'Using invisible ultraviolet light to hit the phosphor powder coated on the inside of the lamp tube And produce visible light. Even by applying different _ powders, visible light of different colors can be produced. There are various types of power-saving bulbs, such as spiral, (four), straight tube, etc., but in any case, you must tear the lamp to protect the seams, the lights are fine, then install the lamp caps, and use the lamp heads to combine the electric posts. The light bulb is energized and illuminated. The first figure shows a conventional light-saving bulb structure. The lamp tube A is provided at both ends of the lamp holder A. The light tube (not shown) is provided inside the lamp cover ^, and the lamp holder a is provided. There are also a number of floating A3, which provide the heat of the age-lighting tube. Based on volume, power saving and long life _, coupled with the improvement of illuminating brightness technology, LED (llght emitting dl〇de, light-emitting diode) has become more and more popular for lighting limbs. Due to the small size, the single luminous lumens are not comparable to the general viewing bulbs, fluorescent lamps or existing Lai Ming lamps. Because of the 4 M392312, the current LED lighting fixtures are all integrated with multiple LEDs. Practical illumination brightness is produced by concentrated illumination. For example, the combination of multiple LEDs in a lampshade can achieve the same or even more efficient lighting effect as a general bulb. However, the high-power LED input power is only 15~20% converted into light, and the remaining 8〇~85%. Then it is converted into heat. If these heats are not properly discharged, the LED die interface temperature will be too high, which will affect the luminous efficiency and reduce the luminous lifetime. The second figure shows the structure of a conventional LED power-saving bulb, which is composed of a plurality of heat-dissipating fins B1 and a lamp holder B3 at the lamp holder and the end, and a heat-emitting fin B1 end combined with a lampshade B2' to provide a light-emitting LED module (Fig. It is not shown in the inside of the lamp cover B2. The heat generated by the LE1D module is directly transmitted to the plurality of heat sink fins β1, and the heat of the heat sink fin surface is directly removed by the air. However, the conventional LED bulb shown in the second figure, because the heat dissipating fin B1 is exposed outside the bulb, it is easy to accumulate dust or/or scale after a period of use, so that the heat dissipation effect is affected, and the user must clean the theorem to maintain Good heat dissipation efficiency, but this is very troublesome. Also, since _: is small between the fins, it is not convenient or easy to clean dust or dirt regularly. [New content] The purpose of this creation is to solve the conventional energy-saving bulb with heat-dissipating fins. The heat-dissipating tabs are exposed outside the bulb. It is easy to accumulate dust or dirt and affect the heat dissipation effect. It is inconvenient and difficult to clean dust or dirt. The problem.

As a choice, the creation can integrally form a closed bottom surface in the heat sink. Alternatively, the wire can be combined with the heat sink and the light emitting device can be disposed on the outer side of the bottom surface. 6 As a seed choice, Xiang Zuo can provide _step to provide - silk and reflected light 'to make the light softer, the diffusing element is fixed by the fixed reading to the position of the heat sink corresponding to the hairline . As a choice - this _ can be set to the vents of the vacant, this heat is quickly discharged out of the lamp holder. The other technical means of the present invention is to integrally form the heat sink body with the thin piece on the (four) wall surface of the lamp holder, the lower phase of the heat sink body is mounted - the bottom plate, and then the light emitting skirt is sighed by the 6 inch bottom plate. It is connected to the lamp holder, so that the heat sink and the light-emitting device are covered in the space formed by the lamp cover and the lamp holder. The straw structure created by the present invention stores the Korean film with good heat and heat dissipation efficiency.
