DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
The present invention will be apparent to those skilled in the art by reading the following detailed description of preferred embodiments thereof, with reference to the attached drawings.
FIG. 1 is a perspective view showing an integrated multi-layered illuminating assembling unit of the present invention, and FIG. 2 is a section view showing an integrated multi-layered illuminating assembling unit of the present invention. The present invention relates to an integrated multi-layered illuminating unit which can adapt to different purposes and locations of use by assembling with multiple units thereof to improve the illuminating range and intensity.
An integrated multi-layered illuminating unit of the present invention mainly comprises a heat dissipating base 1 and two lead wires 3.
The heat dissipating base 1 includes a first front side 11 and a second front side 13, wherein the second front side 13 is located on the opposite side of the first front side 11 of the heat dissipating base 1, and at least one slot compartment 111 is disposed on the first front side 11. As shown in the preferred embodiment of FIG. 1, four slot compartments 111 which are arranged in pairs can be disposed. The second front side 13 forms a plurality of cooling fins 131 where the cooling fins have a gap between each fin.
It should be noted that the number and the configuration of slot compartments 111 should be decided according to the actual needs and situation, so is the shape of the heat dissipating base 1. The preferred embodiment described here is for illustrating purpose only, and the scope and variations of the present invention is not limited thereto. The heat dissipating base 1 can also be the rectangle shape shown in FIG. 3, so the slot compartments 111 are arranged in a straight line with intervals.
As shown in FIG. 1 and FIG. 2, a base surface 1111 and an inner circular wall are disposed in the slot compartment 111 of the heat dissipating base 1, wherein an emitting element 5 is disposed on the base surface 1111 and the emitting element 5 is wire bonded to each other. Two openings 15 are disposed between the second front side 13 and the base surface 1111 of the slot compartments 111. The light emitting elements 5 are arranged in arrays, and can be LEDs or other elements with illuminating functions.
The inner circular wall 1113 is an inclined plane so the light emitted by the emitting element 5 can be reflected by the inner circular wall 1113 to the outside of the slot compartments 111. A reflective mask (not shown in graph) can be installed on the inner circular wall to improve the reflective rate of the emitting element 5, so the irradiation intensity and uniformity of the emitting element 5 are enhanced.
As shown in FIG. 2, two lead wires 3 are wired bonded to the emitting elements 5 to form electrical connections, and two lead frames are installed through the two openings 15, wherein the closer end of the two openings 15 to the slot compartment 111 is sealed with a sealing material 6, and the further end of the two openings 15 from the slot compartment 111 is sealed and fixated with a plug 4. Other than isolating moisture and dust, the sealing material 6 and the plug 4 also serve to fixate two lead frames 3. The sealing material 6 can be silicone resins or epoxy resins with high attachment and high temperature tolerance. The better silicone resins choice should have zero light transmittancy, so when the light emitted by the emitting element 5 incident the silicone resins, the silicone with zero light transmittancy can reflect the emitted light from the emitting element 5 to the outside of the slot compartments 111, therefore improves the light transmission efficiency.
The space within the two openings 15 can be filled with a polymer compound 7 with high heat conduction performance, so two lead frames 3 are embedded and the heat generated can be dissipated to heat dissipating base 1 quickly.
A wireless transmission unit 10 and a power supply unit 20 can be installed on the heat dissipating base 1, wherein the wireless transmission 10 can be a standard IEEE802.11 wireless transmission module or a Bluetooth transmission module, and is at least one of them.
FIG. 4 shows a schematic view of the first preferred embodiment of an integrated multi-layered illuminating assembling unit of the present invention. Followed by the previous description, the present invention can further comprise an optical mask 8 and a diffusing mask 9. The optical mask 8 is located on the light emitting element 5 and is connected with the slot compartment 111, so the slot compartment 111 becomes an enclosed space to prevent moisture and dusts from entering. The diffusing mask 9 is located on the heat dissipating base 1 and is connected with the heat dissipating base. The optical mask 8 and the diffusing mask 9 are used to diffuse the light emitted by the emitting element 5, so the irradiation uniformity can be enhanced.
FIG. 5 shows a utilization drawing of an integrated multi-layered illuminating assembling unit of the present invention. The heat dissipating base 1 can be installed on a wall 200 with a heat insulating block 300 in between. Through the installation of heat insulating block 300, a space for ventilation is generated between the heat dissipating base 1 and the wall 200. Therefore, the heat generated from the heat dissipating base 1 can be conducted to the ventilating space described above, and the heat can be dissipated quickly by the ventilation of the air.
The present invention can be assembled with a plurality of the heat dissipating bases 1, wherein any two adjacent heat dissipating bases 1 can be assembled into different forms of illuminating units by installing the connecting members 100, as shown in FIG. 6. The structure of the heat dissipating base 1 thereof and the assembling relations with the emitting element 5 and the lead wires 3 are described in the paragraphs above therefore will not be mentioned here again.
FIG. 6 shows a schematic view of the second preferred embodiment of a multi-layered illuminating assembling unit of the present invention. Two heat dissipating bases 1 thereof can be assembled and the two heat dissipating bases 1 are configured correspondingly, so the two corresponding sides of the two heat dissipating bases 1 are connected through two connecting members 100. The connecting member 100 includes a connecting grip 100a and two screws 100b. In order to assembled the two heat dissipating bases 1, the connecting grip 100a is placed in a way that the two ends of the connecting grip 100a are on the same side of the two heat dissipating base 1 separately, and then the two screws 100b are fastened on the two ends of the connecting grip 100a to be screwed into the heat dissipating base 1.
In the preferred embodiment, the two connecting members are fixated on the top and bottom of the heat dissipating base 1 separately, with the second front side 13 of the two heat dissipating base 1 facing each other. In other words, the cooling fins 131 of the two heat dissipating bases 1 are facing each other, therefore the slot compartments 111 which are installed with the emitting element 5 should be set up facing outward. Through such configuration of the heat dissipating bases 1, the assembled illuminating unit can have two light beams projecting in different directions, so the irradiation range can be enlarged.
Furthermore, the thickness between the cooling fins 131 of the second front side 13 and the emitting element 5 of the first front side 11 is very thin, thus the heat generated from the light emitting element 5 can be conducted to the cooling fins 131 on the other side immediately. In addition, the ventilating air between the cooling fans 131 can conduct the heat away to keep the heat from building up; therefore, the emitting element 5 can work under proper temperature continuously to keep up the best luminous efficiency.
As shown in FIG. 7, FIG. 8 and FIG. 9, the heat dissipating bases 1 can be arranged into a triangular, quadrilateral, polygon and other possible shapes of illuminating unit depending on the actual number of assembling units used. The sides of the heat dissipating bases 1 can be set as chamfered surface, so the adjacent heat dissipating base 1 can be more united and closer to each other when assembled.
All the slot compartments 111 with the emitting elements 5 should be set up facing outward. As shown in FIG. 7, the preferred embodiment uses three heat dissipating bases 1. The illuminating unit can be a triangular shape illuminating unit with three directions of light beams through proper configuration and assembling. When the emitting elements 5 in all three heat dissipating bases are lit simultaneously, the triangular illuminating unit will give a lighting effect of 360 degrees visually. Therefore, the irradiation range and intensity of the illuminating unit can be increase multiply.
FIG. 10 shows a schematic view of the third preferred embodiment of an integrated multi-layered illuminating assembling unit of the present invention. The heat dissipating base 1 can be installed onto the lamp body 400, wherein the lamp body 400 can cover the diffusing mask 9, and a lamp fitting 410 is disposed on the bottom of the lamp body 400. The lamp body 400 has a containing space (not shown on graph) within, where the wireless transmission unit 10 and the power supply unit 20 can be installed in. This preferred embodiment uses the lamp body 400 of a sphere bulb as example; however, the scope of the invention should not be limited hereto. All the lamp bodies of an illuminating device are included in the scope of the invention.
As shown in FIG. 10, four heat dissipating bases 1 are used and the first front side 11 of the four heat dissipating bases 1 are facing outward of the lamp body 400. Preferably, the four heat dissipating bases 1 are arranged in pairs to form a quadrilateral shape. When the emitting elements 5 of the four heat dissipating bases are lit simultaneously, the quadrilateral illuminating unit will give a lighting effect in all directions visually. Therefore, the irradiation range and intensity can be increased multiply.
The advantage of the disclosure is that the number of the heat dissipating base 1 used to assemble the illuminating unit can be determined based on the purpose and the location of use, and so is the assembling method. In addition, the assembling of the heat dissipating bases only relies on the connecting members 100, and the actual operation of the connecting members is very convenient, fast and simple, thus the production and maintenance process are very time and cost saving. In short, the illuminating unit provided by the present invention can be assembled into suitable forms based on different applications and purposes of use to provide proper irradiation range and intensity.
The preferred embodiment described above is disclosed for illustrative purpose but to limit the modifications and variations of the present invention. Thus, any modifications and variations made without departing from the spirit and scope of the invention should still be covered by the scope of this invention as disclosed in the accompanying claims.
