Description

Lamp structure

This creation relates to a luminaire structure, and more particularly to a luminaire structure having a light-emitting diode.

Light-emitting diodes (LEDs) have been widely used in luminaire structures (such as lamps or bulbs) in daily life, and one of the main problems faced by LED-based luminaire structures is how to effectively remove LED illuminants. The heat energy generated during the time.

The solution to the above problem is roughly to add a fan device (active heat sink) or a heat sink fin (passive heat sink) to the structure of the lamp, and the lamp structure disclosed in Taiwan Patent Publication No. I360625 uses both a fan device and a heat sink fin. The fan unit draws cold air from the outside into the luminaire structure and then allows the cold air to carry away the heat accumulated on the fins.

However, if the air flow path is poorly designed, the heat energy in the structure of the lamp cannot be effectively carried away by the air. For example, in the luminaire structure disclosed in Taiwan Patent Publication No. I360625, the vent hole is beside the fan, and the low pressure generated when the fan rotates will draw outside air from the vent hole into the luminaire structure, so that it is originally exhausted. The air discharged from the holes is not easily discharged.

Moreover, a length of the lamp cover is greater than a length of the plurality of vertical plates.

The above objects, technical features and advantages will be more apparent from the following description.

Please refer to FIG. 1 to FIG. 6 , which are schematic diagrams of a first preferred embodiment of the lamp structure of the present invention, wherein FIG. 1 is a perspective assembled view of the lamp structure 1 and FIG. 2 is a lamp structure 1 3D exploded view, Fig. 3 is a perspective cross-sectional view of the lamp structure 1, Fig. 4 is a rear view of the lamp structure 1, Fig. 5 is a plan sectional view of the lamp structure 1, and Fig. 5A is a schematic view of the air flow path of the lamp structure 1. And FIG. 6 is a perspective view of the socket of the lamp structure 1.

As shown in Figures 1, 2 and 5, the lamp structure 1 can include: a lamp holder 10, at least one air filter 20, a fan device 30, a heat sink 40, a plurality of first lighting devices 50, and a lamp cover 60. . Hereinafter, the technical contents of each component of the lamp structure 1 will be described in order, and then the light-emitting and heat-dissipating methods of the lamp structure 1 will be described.

As shown in FIGS. 2 and 6, the socket 10 has a joint portion 11, an outer ring portion 12, and an inner ring portion 13. The connector portion 11 can be coupled to a light fixture socket (e.g., a light bulb holder, not shown) to receive electrical energy from the light fixture socket. The outer ring portion 12 is similar to a bowl-like structure, and one end thereof is connected to the joint portion 11; the other end not connected to the joint portion 11 is an open end of the outer ring portion 12. The outer ring portion 12 also has an accommodating space for other components to be accommodated.

The inner ring portion 13 is similar to a tubular structure and is disposed in the outer ring portion 12, and one end of the inner ring portion 13 is connected to the inner edge surface of the outer ring portion 12; the other end not connected to the outer ring portion 12 is an inner ring. An open end of the portion 13. The inner ring portion 13 and the outer ring portion 12 may also be integrally formed.

The outer ring portion 12 further has a plurality of first air holes 121 adjacent to (or at) the open end of the outer ring portion 12, and a plurality of second air holes 122 adjacent to (or located at) The joint portion 11; in other words, the first air hole 121 and the second air hole 122 are respectively disposed at opposite ends of the outer ring portion 12.

In addition, the first air holes 121 and the second air holes 122 are separated by the inner ring portion 13 , which means that the first air holes 121 are located outside the inner ring portion 13 and the second air holes 122 are located at the inner ring portion 13 . within. In the present embodiment, the first air hole 121 serves as an air intake hole, and the second air hole 122 serves as a gas exhaust hole.

The shape of the first air hole 121 may be elongated and non-circular. As shown in FIG. 4, the shape of the second air hole 122 may be a fan shape, and the second air holes 122 are arranged in a ring shape and surround the joint portion 11; in other words, the second air holes 122 are distributed around the outer periphery of the joint portion 11.

As shown in FIGS. 1 and 2, at least one air filter 20 (two in this embodiment) is disposed on an outer surface of the outer ring portion 12 and covers the first air holes 121. The air filter 20 can block impurities or dust in the air, making it difficult for impurities or dust to enter the outer ring portion 12 (or the entire lamp structure 1) via the first air hole 121. The air filter 20 can be an air filter, or alternatively an alternate air filter or the like.

It should be noted that if the lamp structure 1 is in an environment with good air quality, the air filter 20 may be omitted; or due to cost considerations or other factors, the air passes. The filter 20 can also be omitted.

As shown in FIGS. 2 and 5, the fan unit 30 is disposed in the inner ring portion 13 of the socket 10 such that the fan unit 30 and the first air hole 121 are separated by the inner ring portion 13. The fan device 30 is farther away from the open end of the outer ring portion 13 of the socket 10 than the first air holes 121; thus, when the lamp structure 1 is in the hanging state, the fan device 30 is higher than the first air hole 121.

Further, by the partitioning of the inner ring portion 13, an air flow path is formed to introduce outside air into the lamp structure 1. The fan unit 30 may be an axial fan whose air blowing direction faces the joint portion 11 (and the second air hole 122), so that outside air is sucked from the first air hole 121 and discharged from the second air hole 122. Since the inner ring portion 13 separates the fan device 30 from the first air hole 121, when the fan device 30 is operated, the outside air sucked from the first air hole 121 needs to pass through the heat sink device 40 at least to pass through the fan device 30.

The heat sink 40 is disposed at the open end of the inner ring portion 13 of the socket 10. The heat dissipating device 40 can have a substrate 41 and a plurality of vertical plates 42. The substrate 41 is disposed at the open end of the inner ring portion 13 and has a uniform through hole 411. The vertical plates 42 are fixed on the substrate 41, and the vertical plates are fixed. 42 is arranged in a ring shape and surrounds the through hole 411 of the substrate 41. The inner edge faces of the risers 42 are also formed with a plurality of fins to increase the area in contact with the air.

In addition, the risers 42 are also connected to each other to form a hollow cylinder. The cross-sectional shape of the hollow cylinder is not limited and may be polygonal or circular. The hollow cylinder has a space inside, and both ends are openings of the space. The space inside the hollow cylinder is permeable to the through hole 411 of the substrate 41 and communicates with the space inside the inner ring portion 13.

It should be noted that the vertical plates 42 can be integrally formed to be connected so as to constitute The hollow cylinder is an integrally formed hollow cylinder. The risers 42 may also be disconnected from each other (not shown), but are still arranged in a ring shape.

In general, the substrate 41 and the vertical plate 42 may be made of a metal material to provide heat conduction. Under the premise of considering the overall weight reduction of the lamp, the substrate 41 and the vertical plate 42 may also be replaced with a heat-conductive plastic material instead of a metal material, or may have the same heat conduction function.

In addition, when the inner ring portion 13 of the socket 10 and the vertical plates 42 (and/or the substrate 41) are manufactured using the same material (for example, both metal or plastic), the inner ring portion 13 can be The vertical plate 42 (and/or the substrate 41) is integrally formed; if the inner ring portion 13 and the vertical plates 42 (and/or the substrate 41) are made of different materials (for example, the inner ring portion 13 is plastic, When the plate 42 is made of metal, the inner ring portion 13 can be formed on the vertical plate 42 (or the substrate 41) by means of injection molding (or burying), so that the inner ring portion 13 and the vertical plate 42 ( Or the substrate 41) can be connected relatively tightly.

As shown in FIG. 5 , the first light-emitting devices 50 are respectively disposed on the vertical plates 42 , and the first light-emitting devices 50 each have a circuit board 51 and a plurality of light-emitting diodes 52 . In addition, one of the first light-emitting devices 50 further has a temperature sensor 53. The circuit board 51 can be attached to the outer surface of the vertical plate 42 , and the light-emitting diode 52 and the temperature sensor 53 are disposed on the circuit board 51 and electrically connected to the circuit board 51 .

The circuit board 51 is further electrically connected to the joint portion 11 of the socket 10 to obtain electric energy, and then drives the light-emitting diode 52 and the temperature sensor 53. The temperature sensor 53 can monitor the temperature within the luminaire structure 1. If the temperature in the lamp structure 1 exceeds a predetermined value, the temperature sensor 53 sends an indication signal to a control device (not shown) on the circuit board 51. After receiving the indication signal, the control device will lower the LEDs 52. The power causes the thermal energy generated by the light-emitting diode 52 to decrease.

It should be noted that the temperature sensor 53 can also be modified to be disposed on a power circuit board (not shown) and then electrically connected to the first light-emitting devices 50. The power circuit board can be housed in the lamp holder 10 and can be attached or stood on the substrate 41.

The lamp cover 60 is disposed at the open end of the outer ring portion 12 of the socket 10 and covers the inner ring portion 13, the heat sink 40, and the first light emitting device 50. A length of the risers 42 is less than a length of the shade 60, but at least half the length of the shade 60. Thus, there may be a suitable spacing between the end of the riser 42 (or hollow cylinder) and the end of the lamp cover 60 to allow air to flow more easily into the hollow cylinder. In the present embodiment, the length of the riser 42 is about 2/3 of the length of the lamp cover 60.

The above is the technical content of each component of the lamp structure 1. Next, the light-emitting and heat-dissipating methods of the lamp structure 1 and the like will be described.

As shown in Fig. 5, the lamp structure 1 is illuminated by the light-emitting diodes 52 of the first light-emitting device 50. Since the first light-emitting devices 50 are arranged in a ring shape, and the light-emitting diodes 52 are arranged in a row along the longitudinal direction of the lamp cover 60, the light transmitted through the lamp cover 60 is relatively uniform.

As shown in FIGS. 5 and 5A, while the light-emitting diode 52 emits light, the fan unit 30 operates to draw the outside air A from the first air hole 121 into the globe 60. Since the first air hole 121 and the fan unit 30 are separated by the inner ring portion 13 and the heat sink 40, the sucked air A needs to bypass the heat sink 40, and the fan unit 30 is discharged from the outside of the lamp structure 1.

In particular, the inhaled air A will flow first through the outer surface of the riser 42 and first The light-emitting device 50 reaches the end of the lamp cover 60 (that is, the free end of the vertical plate 42 and the open end of the hollow cylinder), enters the hollow cylinder, is driven by the fan device 30, and is finally discharged to the lamp through the second air hole 122. Structure 1 is outside.

When the inhaled air A flows along the above path, it can sufficiently contact the upright plate 42 so that the heat energy on the riser 42 can be effectively carried away by the air A. Further, when the air A flows along the above path, the air existing in the globe 60 can flow almost, so that hot air is less likely to accumulate at the end of the globe 60 (because the length of the riser 42 and the length of the shade 60 are not The difference is too big).

Please refer to FIG. 7, which is a plan sectional view showing a second preferred embodiment of the lamp structure of the present invention. The luminaire structure 2 of the second embodiment differs from the luminaire structure 1 of the first embodiment in that the luminaire structure 2 includes a second illuminating device 70 in addition to the plurality of first illuminating devices 50.

The second illuminating device 70 is disposed at the free end of the vertical plate 42 (that is, the open end of the hollow cylinder), and the second illuminating device 70 also has a circuit board 71 and a plurality of illuminating diodes 72. However, the circuit board 71 of the second lighting device 70 has a plurality of through holes 711 such that the circuit board 71 does not block the flow of air into the hollow cylinder. In addition, the second light emitting device 70 can also have a temperature sensor 73.

The other components of the luminaire structure 2 are the same as those of the luminaire structure 1, so the same components will not be described. Since the luminaire structure 2 has a second illuminating device 70, the emitted light is more uniform.

Please refer to FIG. 8 , which is a plan sectional view showing a third preferred embodiment of the lamp structure of the present invention. The luminaire structure 3 of the third embodiment and the luminaire of the first embodiment The difference between the structure 1 is that the first air hole 121 of the lamp structure 3 is formed on the lamp cover 60. In other words, the lamp cover 60 has a plurality of first air holes 121, and the first air holes 121 and the second air holes 122 are opposite to the inner ring. The portions 13 are respectively provided on both sides (outer side and inner side) of the inner ring portion 13. Further, the second air hole 122 of the lamp structure 3 is farther from the joint portion 11 than the second air hole 122 of the lamp structure 1, but is still disposed inside the inner ring portion 13.

Further, the first air hole 121 can be disposed at the bottom end of the lamp cover 60, and the heat energy of the lamp cover 60 can still be discharged by the driving of the fan 30; further, the air filter 20 of the lamp structure 3 is disposed on the lamp cover 60. The outer surface is covered with the first air holes 121.

The other components of the luminaire structure 3 are the same as those of the luminaire structure 1, so the same components will not be described.

The above is a description of various preferred embodiments of the luminaire structure of the present invention. In conclusion, the luminaire structure of this creation has at least the following characteristics:

1. When the air sucked into the structure of the lamp is flowing, it can flow through all the places of the vertical plate, and the existing air in the lamp cover can flow, so that the overall structure of the lamp can have better heat dissipation effect.

2. The air filter can block impurities or dust in the air, so that impurities or dust do not enter the structure of the lamp and affect the operation of the illuminating device.

3. The temperature sensor senses the temperature within the structure of the luminaire, thereby controlling the operating power of the illuminating diode.

4. The first illuminating device may be arranged in a ring shape to uniformly emit light to the surroundings.

5. The second illuminating device can further increase the illuminating direction of the luminaire structure.
