Based on the system solution provided by the present invention, the achievable control functions may include:

First, the luminous intensity adjustment:

The illumination intensity of the high-power LED lamp 300 is controlled by the remote control device 100 of the user to adjust the illumination intensity. As shown in FIG. 2, as an embodiment, the driving unit 330 of the high-power LED lamp 300 can directly regulate the LED module. The driving current of 320 can be located at the input end of the LED module 320 in principle, and is connected to the control unit 310 and controlled by the control unit 310. When the user inputs a corresponding instruction through the remote control device 100 (such as a brightening or darkening command, the response can be intuitively reflected. In the interface of the remote control device 100, it is transmitted to the control unit 310 of the high-power LED lamp 300 through the communication network 200, and the control unit 310 sends a signal to the driving unit 330 according to the instruction. The unit 330 provides a current value of a specific intensity to the LED module 320, thereby controlling the LED module 320 to emit light at a specific light intensity. As shown in FIG. 3, as a preferred solution, the driving unit 330 is designed in two stages, and is divided into an AC-DC module 331 and a DC-DC module 332. The AC-DC module 331 is connected to the mains input, DC-DC mode. The group 332 is connected to the AC-DC module 331 and connected to the control unit 310 and controlled by the control unit 310. The mains input is first converted into DC by the AC-DC module 331 to the DC-DC module 332, and the DC-DC module 332. The control unit 310 controls the input DC to be converted into a suitable output DC to provide power to the LED module 320.

Here, two typical embodiments in which the driving unit 330 drives the LED module 320 can be cited. As shown in FIG. 4, due to the linear relationship between the operating current of the LED and the input, it is known that the LED module 320 is clamped to the front end of the LED module 320. The DC-DC module 332 can adjust the current level linearly and steplessly, thereby continuously increasing or weakening the luminous intensity of the LED module 320. In addition, a non-linear multi-level dimming method, such as 256-step dimming, can be used with a total brightness of 1/256. Or as shown in FIG. 5, a plurality of groups of driving units 330 can be respectively used to drive a plurality of LED modules 320. For example, in a 1000 W high-power LED lamp, four groups can be set, and each group has a driving unit 330. And the paired LED modules 320, each of the LED modules 320 can take 300W, and the DC-DC modules 332 of the four driving units 330 are respectively connected to the control unit 310, and are separately controlled by the control unit 310; Level dimming, for example, when the minimum intensity illumination is required, the control unit 310 can control only one set of driving units 330 and the corresponding LED module 320 to work, and calculate the power loss in actual application, and emit light at about 250 W; When the highest intensity illumination is required, the control unit 310 controls the four groups of driving units 330 to operate, so that the corresponding LED modules 320 of the four groups of driving units 330 emit light, so that after calculating the actual power loss, the total power is about 1000W, that is, the maximum light intensity is achieved.

Second, the color temperature adjustment:

The color temperature of the high-power LED lamp 300 is controlled by the user's remote control device 100. The basic principle is that the LED chip includes a three-primary LED light source, that is, a mixture of different spectral wavelengths of the RED LED light source 321, the GREEN LED light source 322, and the BLUE LED light source 323. The final color temperature of the LED chip is obtained, and the color temperature of the LED light source of each primary color is related to the brightness thereof. Therefore, the embodiment of the present invention can control the respective brightness of the three primary color LED light sources, and finally the LED module 320 is mixed. Different color temperatures; as shown in FIG. 6, in the preferred embodiment of the present invention, the respective brightness of the three primary color LED light sources may also be clamped by a color temperature driving circuit 340 at the input end of the power supply, by regulating R, G, The output currents of the respective color temperature driving circuits 340 of the B primary color LED light sources are used to obtain the primary color light of different brightness, and the light of the different color temperatures of the LED module 320 is obtained after the light is mixed.

The instruction, if the color temperature is lowered, is sent to the control unit 310 through the communication network 200, and the corresponding command is issued by the control unit 310, which can improve the brightness of the RED LED light source 321 or reduce the brightness of the BLUE LED light source 323, thereby achieving an increase. Or turn down the effect of color temperature.

The transmission component 420 can control the action of the lens 350 or the LED module 320 to adjust the relative distance between the two, since the light emitted by the LED module 320 is refracted via the lens 350. After the illumination is applied to the environment, the distance of the lens 350 relative to the LED module 320 is related to the angle of the refracted light. Therefore, by adjusting the distance between the two, the final illumination angle adjustment can be realized; the user inputs the remote control device 100. Corresponding instructions, such as an increased illumination angle, the control signal is received by the control unit 310 via the communication network 200, and the motor 4 of the angle control device 400 is controlled by the control unit 310. 10 forward action or reverse action, as shown in FIG. 9 , the relative proximity of the lens 350 and the LED module 320 is controlled via the transmission component 420 , thereby increasing the illumination angle of the light of the LED module 320 after passing through the lens 350 , thereby The illumination angle of the high-power LED lamp 300 is increased. Conversely, by controlling the relative distance between the lens 350 and the LED module 320 via the transmission component 420, the illumination angle of the LED module 320 after passing through the lens 350 can be reduced, thereby reducing The illumination angle of the high-power LED lamp 300 is reduced; with this structure, the stepless regulation can also be conveniently implemented, which is convenient for freely controlling the illumination angle.

To achieve wide-angle directional control, the transmission assembly 520 includes at least two dimensions of steering structure, and the corresponding steering motor 510 includes at least two dimensions of driving power; the user is in the remote control device. 100 inputs a corresponding command, if the high-power LED lamp 300 is to be controlled to rotate in a specified direction, the control signal is transmitted to the control unit 310 via the communication network 200, and the control unit 310 thereby controls the steering motor 510 of the steering device 500 to be designated In the directional action, the steering motor 510 drives the transmission component 520, that is, the main body of the high-power LED lamp 300 is rotated in a specified direction, thereby realizing the adjustment of the illumination direction, and the structure can be conveniently implemented steplessly. Easy to use for free control of the direction of the light.

Five, fault diagnosis:

The system solution of the present invention is a two-way linkage between the user terminal, that is, the remote control device 100 to the illumination terminal, that is, the high-power LED lamp 300. Therefore, in addition to the above-mentioned active control of the high-power LED lamp 300 by the user, an additional operation may be added. The high-power LED lamp 300 feeds back information to the user's function setting; as shown in FIG. 12, the present invention can add a fault diagnosis module 360 to the circuit structure of the high-power LED lamp 300, which is embodied in principle on the power supply side and On each component, and connected to the control unit 310, when the power supply is abnormal and a certain part fails, it can be detected in time, and the result is sent by the control unit 310 via the communication network 200 to send a short message, identification information or E- Mail to the user to remind the user to handle the fault.

Sixth, automatically adjust the luminous intensity:

As shown in FIG. 13, the high-power LED lamp 300 can be provided with a detection sensor 370 connected to the control unit 310. The sensor 370 can be an infrared sensor or an image sensor, and the scanning is large. The illumination area of the power LED lamp 300 is increased when the number of people in the area increases, such as more than 3 people, and is fed back to the control unit 310. The control unit 310 controls the drive unit 330 to increase the output, thereby improving the illumination intensity of the LED module 320, thereby achieving high power. The brightness of the LED lamp 300 is enhanced. When the number of people is too small, the sensor 370 feeds back, and the control unit 310 controls the driving unit 330 to reduce the output, thereby reducing the illumination intensity of the LED module 320 to reduce the illumination brightness. Or sleep; so that intelligent light can be automatically adjusted, and the dimming result can be fed back to the customer's remote control device 1200.

As shown in FIG. 21, in another preferred embodiment of the present invention, the outer heat sink 302 is provided with radiating fins 3021 on the outer circumference, and the fins may also be "Y" or "T" shaped. The heat sink fins can also be connected to each other, and have the advantages of a chimney effect while having a large heat dissipation area.

As shown in FIG. 23, the heat pipes in the first heat pipe group 303 and the second heat pipe group 304 of the present invention are generally in the shape of a circular tube, which is preferably a groove provided in the tube by Yeh-Chiang Technology. Sintered composite pipe, and the number of grooves is greater than 120. In order to achieve high power illumination, the optimal thermal resistance is less than 0.05 ° C / watt; the heat pipe needs to be bent to form a U shape, and multiple assembly is required. They are applied together, so it is better to press-fit the heat pipe to better fit the relevant components to achieve better heat transfer.

According to the above structure, the annular column formed by the U-shaped end of the heat pipe of the first heat pipe group 303 and the second heat pipe group 304 is disposed just outside the inner heat sink 301 and is connected to the inner heat sink 301. The outer wall of the outer cylinder 3012 is bonded to each other; on the other hand, it is just attached to the wall surface of the through hole 3020 of the outer heat sink 302, and reference is made to Fig. 22.

In a preferred embodiment, the outer wall of the outer cylinder 3012 of the inner heat sink 301 is axially provided with a plurality of first grooves 3015 for engaging the first heat pipe group 303 and the second heat pipe group 304. Each heat pipe of the U-shaped end is configured such that the heat pipes of the U-shaped end can be closely matched and fit in the first groove 3015, wherein the first groove 3015 can be made into an arc shape, and the first heat pipe group 303 and The side of the heat pipe of the second heat pipe group 304 that is in contact with the first groove 3015 corresponds to a circular arc surface.

Similarly, the wall surface of the through hole 3020 of the outer heat sink 302 is preferably provided with a plurality of second grooves 3016 in the axial direction, and the second groove 3016 is configured to match the U shape of the first heat pipe group 303 and the second heat pipe group 304. Each of the heat pipes of the end is configured such that the heat pipes of the U-shaped end can be closely matched and fit in the second groove 3016, wherein the second groove 3016 can be arcuate, and the first heat pipe group 303 and the second heat pipe The side of the heat pipe of the group 304 that is in contact with the second groove 3016 corresponds to a circular arc surface.

Thus, without changing the shape of the heat pipe and simplifying the process, not only the heat pipe is firmly fixed, but also the inner heat sink 301 and the outer heat sink 302 are positioned, and the circular shape of the heat pipe is not changed, and the ideal fixing effect can be achieved. It is also more compact and reasonable; on the other hand, the close fitting of the curved surface can increase the contact area, thereby increasing the effective heat transfer area from the heat pipe to the inner heat sink 301 or the outer heat sink 302, so that the three are fitted Tight and optimal heat transfer.

In addition, as a heat dissipation efficiency of the inner heat sink 301 and the outer heat sink 302, in a preferred embodiment, the inner heat sink 301 is provided with fins 3013 at a position closest to the first groove 3015 so as to be transmitted from the heat pipe. The heat can be transferred to the fins 3013 at the shortest distance, and is radiated by the heat exchange of the fins 3013 with the air. Similarly, the heat sink fins 3021 are disposed at the nearest position of the plurality of second recesses 3016 on the outer heat sink 302, so that the heat transferred from the heat pipe can be transmitted to the heat dissipation fins 3021 at the shortest distance by the heat sink fins. The sheet 3021 is exchanged by heat exchange with air.

The invention can be applied to various ultra-high power LED lamps. The heat generated by the LED module 320 as a heat source is the most important heat source of the lamp. When the LED module 320 is in operation, the heat is first transmitted to the first heat pipe group 303 by the U. The flat surface 3030 formed by the middle section allows the first heat pipe group 303 to receive heat, and since the second heat pipe group 304 is in contact with the first heat pipe group 303, the heat of the first heat pipe group 303 can be quickly shared to jointly heat Transferred to the respective U-shaped ends, since the U-shaped ends respectively contact the outer wall of the cylinder 3012 outside the inner heat sink 301 and the wall surface of the through hole 3020 of the outer heat sink 302, the heat is divided into two paths, which are respectively transmitted to The inner heat sink 301 and the outer heat sink 302 cooperate to dissipate heat by the inner heat sink 301 and the outer heat sink 302; in order to achieve complete heat dissipation effect, the total heat dissipation power of the first heat pipe group 303 and the second heat pipe group 304 are added. It must be greater than or equal to the power of the LED module 320, so that the heat dissipation speed of the first heat pipe group 303 and the second heat pipe group 304 can catch up with the speed of heat generated when the LED module 320 operates.

According to the above structure, the present invention can be applied to an ultra-high power LED lamp. As shown in FIG. 24, the equivalent thermal resistance heat dissipation path of the present invention is shown. The heat generated by the LED module 320 during operation is known. Firstly, the first heat pipe group 303 and the second heat pipe group 304 are sequentially transferred to the first heat pipe group 303 and the second heat pipe group 304. The first heat pipe group 303 and the second heat pipe group 304 can be equivalent to a thermal superconductor during heat conduction, and the heat is quickly transmitted. The heat generated by the first heat pipe group 303 and the second heat pipe group 304 is divided into two paths, one of which is transmitted to the inner heat sink 301, and finally the inner heat sink 301 exchanges heat with the air to achieve heat dissipation. The other way is passed to the outer heat sink 302, and finally the heat is exchanged by the outer heat sink 302 for air heat exchange. It can be seen that the solution of the present invention is equivalent to two heat dissipating portions having two parallel connections, and the heat dissipating effect is ideal because it dissipates heat for the unique LED module 320.

After the lamp is installed, one side of the LED module 320 is generally directed downward to illuminate, and generally, a cover 8 is additionally provided outside the LED module 1 for protection. The LED module 320 generates heat during operation. In addition to being transmitted by the inner heat sink 301 and the outer heat sink 302, on the side close to the LED module 320, the cooler air rises through the inner heat sink 301 and/or the outer heat sink. The chimney effect generated by the channel of 302 gradually absorbs the heat on the inner heat sink 301 and the outer heat sink 302 to form hot air, and finally flows out from the upper port of the channel, so that a good heat dissipation effect can be achieved by looping.

It can be seen that through the above scheme, the invention firstly creates a dimmable high-power LED lamp and a matching lighting system.
