Description

  The present invention relates to an LED bulb, and more particularly to an LED bulb having an excellent heat dissipation effect.

  As shown in FIG. 1, a conventional LED bulb 1 includes a lamp cap 11, a bulb base 12 connected to the lamp cap 11, a lamp housing 13 installed on the bulb base 12, and a core tube installed in the lamp housing 13. 14, a plurality of LED plates 15 installed on the core tube 14, a valve core 16 installed in the valve base 12 and connected to the core pipe 14, and a circuit board 17 connected to the valve base 16. The core tube 14 is arranged in an annular shape around the axis to form a hollow column. At the same time, a plurality of concave tanks 141 are opened on the core tube 14. Thereby, each LED plate 15 can be installed in the concave tank 141, and the illumination area is expanded by installing the core tube 14, and the hollow design of the core tube 14 and the installation of the valve core 16 are used. And a heat dissipation effect can be achieved. Therefore, the LED bulb 1 realizes the effects of illumination and heat dissipation at the same time.

  However, the following disadvantages were discovered by actual use. One is that the core tube 14 and the valve pedestal 16 are connected and the valve pedestal 16 is installed in the valve pedestal 12, but the volume occupied by the valve pedestal 12 is excessive due to the installation relationship of the valve pedestal 12. . As a result, the space that the LED bulb 1 can use for illumination is obstructed, and the illumination area of each LED plate 15 is also affected somewhat. Further, the valve core 16 has a heat dissipation effect. However, since the valve core 16 is enclosed in the valve base 12, the heat guided and dissipated through the core tube 14 is covered by the valve base 12. It is not easy to dissipate. If the LED bulb 1 continues to be lit and emits heat energy, the temperature in the valve base 12 cannot be lowered. On the contrary, in a high temperature environment, the circuit board 17 and the LED plate 15 are overheated. Indirectly incurs damage. The present invention has been made in view of the above-described drawbacks of conventional LED bulbs.

  The problem to be solved by the present invention is that the LED bulb can be easily replaced and used without changing the external shape, the heat can be dissipated quickly, and the occurrence of the damage phenomenon caused by the overheating of the LED bulb. It is to provide an LED bulb that can be significantly reduced.

In order to solve the above problems, the present invention provides the following LED bulb.
The LED bulb includes a lamp housing, a lamp cap connected to the lamp housing, a core tube installed in the lamp housing, a plurality of LED plates installed on the core tube, and a controller for controlling on / off of the LED plate. Prepared,
The controller is installed in the housing installation space of the core tube,
Thereby, without changing the external shape of the LED bulb, not only the user can replace itself, but also the convenience of use can be expanded,
In addition, since one end of the core tube and the lamp cap are connected to each other, the heat energy generated when the LED plate is used is guided through the position of the core tube, the lamp cap, and the lamp housing. Thus, heat can be quickly dissipated and the occurrence of LED bulb damage caused by overheating can be greatly reduced.

  The LED bulb of the present invention can be installed by applying the controller inside the core tube, and can be installed in the conventional bulb shape, and does not occupy space and can be replaced by the user himself / herself. Convenience can be expanded. In addition, since the core tube and lamp cap are connected to each other, the brightness of the illumination is completely unimpeded, and the heat energy is quickly conducted, quickly radiating through the position of the lamp cap and lamp housing. Therefore, the optimum heat dissipation effect can be achieved. In this way, the LED bulb can be prevented from being damaged by high heat, so that the object of the invention can be reliably achieved.

It is a three-dimensional view of the first embodiment of the present invention. It is a schematic diagram of the first embodiment of the present invention. It is a three-dimensional view of the second embodiment of the present invention.

  The best mode for carrying out the present invention will be described below in detail with reference to the drawings.

  As shown in FIGS. 2 and 3 which are three-dimensional exploded views and three-dimensional views of the first embodiment of the LED bulb of the present invention, the LED bulb 3 has a lamp housing 31, a lamp cap 32 connected to the lamp housing 31, and a lamp housing 31. A core tube 33 to be installed, a plurality of LED plates 34 to be installed on the core tube 33, and a controller 35 for controlling on / off of the LED plates 34 are provided. Among them, the lamp housing 31, the lamp cap 32, the LED plate 34, and the controller 35 are similar to the conventional structure and will not be described in detail. A hollow accommodation installation space 331 is formed at the center of the core tube 33, and the controller 35 is accommodated and installed therein. The core tube 33 can be designed in various shapes. In this embodiment, an octagon is taken as an example. A plurality of sets of localization ribs 332 are provided in a protruding shape around the outer periphery of the core tube 33, and the LED plates 34 are respectively engaged and localized in the localization ribs 332. Furthermore, one end of the core tube 33 is mutually connected to the lamp cap 32, whereby the heat energy generated by the LED plate 34 is transmitted via the positions of the core tube 33, the lamp cap 32, and the lamp housing 31 to be dissipated. The In this embodiment, in order to enhance the rapid divergence of heat energy due to the position of the lamp housing 31, a heat dissipation gel 36 (see FIG. 4) is added at the joining position of the lamp housing 31 and the lamp cap 32.

  As shown in FIGS. 3 and 4, the controller 35 is installed in the accommodation installation space 331 of the core tube 33 after assembly. Therefore, the controller 35 is installed on a conventional LED bulb 1 that is homologous to the overall outline shown in FIG. Moreover, it is possible to control on / off of the illumination of each LED plate 34 without occupying an excessive space, and further, disassembly and replacement can be performed at any time, thereby improving the convenience of use. In use, when the controller 35 is energized, each LED plate 34 is activated to emit light. At the same time, each LED plate 34 is installed on the core tube 33, and the core tube 33 is directly connected to the head 32, so that the brightness of the LED bulb 3 is not shielded at all, and the light emitted from each LED plate 34. Is emitted completely outside. Further, heat energy generated when each LED plate 34 emits light is led out by the hollow core tube 33. In addition, since the core tube 33 is connected to the lamp cap 32, the lamp cap 32 and the lamp housing 31 are directly connected, thereby greatly increasing the heat dissipation area. Thus, heat energy is quickly dissipated through the lamp cap 32 and lamp housing 31 positions. Thus, the thermal energy generated by the light emission of the LED plate 34 can continue to be enclosed in the LED bulb 3, and the phenomenon that the LED bulb 3 is damaged by high heat can be avoided, and the optimum heat dissipation effect can be achieved. it can.

  As shown in FIG. 5 which is a three-dimensional view of the second embodiment of the present invention, the LED bulb 3 includes a lamp housing 31, a lamp cap 32, a core tube 33, an LED plate 34, and a controller 35, as in the first embodiment. The lamp housing 31 includes a light transmission part 311 and a heat dissipation part 312 that is connected to the light transmission part 311 and that has the opposite end connected to the lamp cap 32. Between the heat dissipation 312 and the core tube 33, a plurality of heat dissipation ribs 37 are installed at intervals. As a result, the heat energy generated when the LED plate 34 emits light is dissipated by the core tube 33 and the lamp cap 32, and is further dissipated by the heat dissipating ribs 37 and the heat dissipating part 312, greatly expanding the heat dissipating area of the LED bulb 3. The heat dissipation effect can be further improved.
