Description

  The present invention relates to a light emitting module, and more specifically to a light emitting module having LEDs.

  In recent years, light emitting diodes (LEDs) have been widely used and become brighter with advanced technology. The brightness of the LED is much better than the conventional lighting device. In addition, LEDs are compact and light, have a long lifetime, good vibration resistance, and can react in a short time. As a result, LEDs are expected to replace conventional lighting devices.

  However, LEDs are not without problems. LED lighting devices are still relatively large in size and there is a need to improve their heat dissipation. In addition, the power of the LDE device is cut off and inconvenient when the current is too high. Therefore, it is important to design a LED lighting device that is small and has good heat dissipation results. Also, the problem of power failure during overcurrent should be solved.

  The light emitting module includes an annular carry plate, a top plate component, a plurality of circuit boards, a plurality of first LEDs, a plurality of second LEDs, and a drive circuit. The annular carry plate has a first end and surrounds the receiving space. The top plate component is disposed at the first end. A plurality of circuit boards are disposed around the annular carry plate and electrically connected to the top plate component. The plurality of first LEDs are arranged on the circuit board. The plurality of second LEDs are arranged on the top plate component. The drive circuit is disposed in the accommodation space and is electrically connected to the top plate component. The drive circuit is a circuit for driving the plurality of first LEDs and the plurality of second LEDs.

  The invention may be more fully understood from the detailed description set forth herein, taken in conjunction with the accompanying drawings for illustrative purposes only. Accordingly, the present invention is not limited to this disclosure.

It is a perspective view which shows the light emitting module which concerns on 2nd Embodiment of this invention. It is a perspective view which shows the light emitting module which concerns on 3rd Embodiment of this invention.

  In the following detailed description, for purposes of explanation, numerous specific details are set forth in order to provide an understanding of embodiments of the present invention. It will be apparent, however, that one or more embodiments may be practiced without these specific details. In other instances, well-known structures and well-known devices are schematically shown in order to simplify the drawing.

  FIG. 1 is a perspective view illustrating a light emitting module according to a first embodiment of the present invention. FIG. 2 is an exploded view of FIG. FIG. 3 is another exploded view of FIG. As shown in FIGS. 1 to 3, the light emitting module 10 includes an annular carrying plate 100, a top plate component 200, a plurality of circuit boards 300, a plurality of first LEDs 400, and a plurality of light emitting modules 10. The second LED 500, the drive circuit 600, the support plate 700, the connection wiring group 800, and the adapter 900 are included.

  The annular carry plate 100 has a first end 110, a second end 120 opposite to the first end 110, and a plurality of grooves 130. The annular carry plate 100 surrounds and forms the storage space 150.

  The top plate component 200 is disposed at the first end 110 and includes a first plate 210 and a second plate 220. The first plate 210 is attached to the second plate 220.

  The plurality of circuit boards 300 are arranged on the annular carry plate 100 and surround it. Furthermore, the circuit board is electrically connected to one side of the second plate. In this embodiment, the circuit board 300 is firmly held in the groove 130.

  The plurality of first LEDs 400 are arranged on the plurality of circuit boards 300. On the other hand, the plurality of second LEDs 500 are disposed on one side of the second plate 220 away from the first plate 210. The plurality of second LEDs 500 are electrically connected to the first plate 210.

  The drive circuit 600 is located in the storage space 150 and is electrically connected to the first plate 210 of the top plate component 200. The drive circuit 600 is a circuit for driving the plurality of first LEDs 400 and the plurality of second LEDs 500. In this embodiment, the drive circuit 600 has a resettable fuse (not shown). If the current is too high, the brightness of the plurality of first LEDs 400 and the plurality of second LEDs 500 decreases due to the use of resettable fuses. When the current returns to normal, the brightness of the plurality of first LEDs 400 and the plurality of second LEDs 500 returns to normal. Thereby, the problem of power supply abnormality caused by overcurrent is solved. Furthermore, the drive circuit 600 of this embodiment is located in the storage space 150 so as to reduce the size of the light emitting module 10.

  The support plate 700 is disposed on the annular carry plate 100 and covers a part of the second end 120. The other part of the second end 120 that is not covered by the support plate 700 forms two air outlets 140. The two air outlets 140 communicate with the storage space 150 and can dissipate heat generated by the light emitting module 10. In other embodiments, the number of air outlets 140 may be one or more. The air outlet 140 may be formed in other shapes. That is, in another embodiment, the annular carry plate 100 has at least one air outlet 140 ′ (as shown in FIG. 4 which is a perspective view showing a light emitting module according to a second embodiment of the present invention). It may be designed as follows. The support plate 700 includes two first line management holes 720 and two cooling holes 710. The two cooling holes 710 communicate with the storage space 150. Use of the two cooling holes 710 improves the heat dissipation effect of the light emitting module 10. In other embodiments, the number of first wiring operation holes 720 and the number of cooling holes 710 may be one or more.

  One end of the connection wiring group 800 is connected to the drive circuit 600. On the other hand, the other end passes through the two first wiring operation holes 720.

  One side of the adapter 900 is disposed on the support plate 700. The adapter 900 covers the air outlet 140. The adapter 900 has two second wiring operation holes 910 and six air holes 920. The other end of the connection wiring group 800 extending from the drive circuit 600 passes through the two second wiring operation holes 910. The six air holes 920 communicate with the two air outlets 140. Since the connection wiring group 800 passes through the first wiring operation hole 720 and the second wiring operation hole 910, the wiring of the light emitting module 10 is orderly, and the user can connect them easily and conveniently. The six air holes 920 communicate with the two air discharge ports 140. As a result, the heat generated by the light emitting module 10 is dissipated through the two air outlets 140 and the six air holes 920. Thereby, the heat dissipation effect of the light emitting module 10 is improved. In this embodiment, the adapter 900 is for a T20 lamp holder, but is not limited to this. In other embodiments, the adapter 900 may be designed to be suitable for a T16 lamp holder. In other embodiments, the number of the second wiring operation holes 720 may be one or more. In other embodiments, the number of air holes 920 may be one or more.

  Furthermore, another structure of the light emitting module is provided. FIG. 5 is a perspective view showing a light emitting module according to a third embodiment of the present invention. As shown in FIG. 5, the light emitting module 10 ′ of this embodiment is the same as the light emitting module 10, and only the differences will be described.

  The adapter 900 'is for an S25 lamp holder and has an annular outer surface 950 and five limit blocks 960. Five restriction blocks 960 are disposed on the annular outer surface 950. In this embodiment, the distances D1 from three of the five restriction blocks 960 to the support plate 700 are equal. On the other hand, the distance D2 from the remaining two of the five restriction blocks 960 to the support plate 700 is different from the distance D1. In this embodiment, the five restriction blocks 960 are designed to fit any type of S25 lamp holder. For example, it is model no. BAY15D (1157) S25 lamp holder, model no. BAZ15D S25 lamp holder, model no. BA15d S25 lamp holder, model no. BAU15S S25 lamp holder or model no. Used for the BA25S (1156) S25 lamp holder. Further, in one embodiment, the number of restriction blocks 960 is three and the vertical distances from the three restriction blocks 960 to the support plate 700 are equal. In some embodiments, the number of restriction blocks 960 is three and the vertical distance from at least two of the three restriction blocks 960 to the support plate 700 is different.

  The light emitting module may further include a cover 990 (as shown in FIG. 1, FIG. 2, FIG. 3, FIG. 4 or FIG. 5). The cover 990 covers the plurality of first LEDs 400 and the plurality of second LEDs 500. The cover 990 is used to prevent the light emitting module structure from being damaged, and can make the entire appearance beautiful while hiding the light source. In addition, the cover 990 may be changed to a bright color and can be formed integrally with the components to be connected.

  In the light emitting module of the present disclosure, the drive circuit is stored in the storage space so that the size of the light emitting module is reduced. Moreover, a part of 2nd edge part which is not covered with the support plate forms an air discharge port. The air holes of the support plate communicate with these air discharge ports. Thereby, the heat dissipation effect of the light emitting module is improved.

  Further, the support plate includes a cooling hole communicating with the storage space to further improve the heat dissipation effect.

  Furthermore, the drive circuit of the light emitting module has a resettable fuse for solving the problem of power supply abnormality caused by overcurrent.
