First Embodiment

Referring toFIG. 1andFIG. 2, the present disclosure provides a light emitting diode lamp, including: a main body10and a heat sink20.

First, the main body10includes a light emitting module101disposed therein. The light emitting module101includes a first circuit board102, at least one light emitting element1020and a dynamic light adjustment module1010. Each of the light emitting element1020and the dynamic light adjustment module1010are disposed on the first circuit board102. The dynamic light adjustment module1010has multiple light adjustment elements respectively corresponding to the light emitting elements1020. The surface on the main body10opposite to the heat sink20has a circular groove serving as a light exit portion. The main body10can be made of metal or metal alloys, such as aluminum or aluminum alloys. The bottom of the circular groove of the main body10has a light scattering structure mainly for improving the light scattering ability of the light source. The light scattering structure can refract light from the light emitting element1020outwards, focusing them on a specific direction. However the present disclosure is not limited hereto.

The light emitting module101is made of multiple chips. The multiple chips are at least one light emitting element1020and a dynamic light adjustment module1010. The multiple chips are arranged in array. The light emitting module101is electrically connected to the first circuit board102. The light emitting element1020is mainly used for lighting and can include at least one white light emitting diode chip. The main function of the dynamic light adjustment module1010is to adjust the color of the light source. The light adjustment elements are respectively at least one blue light emitting diode chip1011, at least one red light emitting diode chip1012, and at least one green light emitting diode chip1013.

In the present embodiment, the light emitting module101is formed by multiple chips. The multiple chips are three light emitting elements1020and a dynamic light adjustment module1010. The three light emitting elements1020are arranged in array and respectively enclose the dynamic light adjustment module1010. The light emitting module101is electrically connected to the first circuit board102. The light emitting elements1020are mainly used for lighting. The three light emitting elements1020can include a first white light emitting diode chip1014, a second white light emitting diode chip1015, and a third white light emitting diode chip1016. The main function of the dynamic light adjustment module1010is to adjust the color of the light source. The dynamic light adjustment module1010has light adjustment elements respectively corresponding to the light emitting elements1020. The light adjustment elements are respectively a blue light emitting diode chip1011, a red light emitting diode chip1012, and a green light emitting diode chip1013. However the present disclosure is not limited hereto.

Next, the heat sink20includes a heat sink base and multiple heat sink fins201. One side of the heat sink base is connected to the main body10. The other side of the heat sink base is connected to the multiple heat sink fins201. By this configuration, the heat sink fins201provide a heat dissipating function for the main body10. For example, the multiple heat sink fins201can be made of metal and capable of meeting the heat dissipation requirement of light emitting diodes operating for long periods of time. According to need, the user can dispose the light exit portion of the main body10on a lamp holder, decoration, or other objects with a groove, rendering the present disclosure with a wider range of application. However, the present disclosure is not limited hereto.

The present disclosure further includes a reflecting unit30disposed on the main body10. The main body10has at least one magnetic unit within embedded on the inner surface of the circular groove. In other words, at least one magnetic permeable unit corresponding to the magnetic unit is disposed on the cone shaped surface of the reflecting unit30, mainly for magnetically connecting to the magnetic unit. For example, when the user disassembles the reflecting unit30from the main body10, he can easily disassemble or install through the magnetic attraction between the magnetic permeable unit and the magnetic unit. Additionally, the magnetic unit can be a magnet, and the magnetic permeable unit can be a screw, screw cap, or other unit made from magnetically permeable material not limited herein.

The outer surface of the reflecting unit30exhibits a round cone shape, whose diameter gradually decreases in the direction of the main body10. Moreover, the reflecting unit30has a scattering structure and a partition (not shown in the figure). The main object of the scattering structure is to improve the scattering ability of the light source. The light scattering structure can refract light from the light emitting element1020outwards, focusing them on a specific direction. Therefore, when the user installs the present disclosure on top of a lamp holder with lighting, this configuration further increases the luminosity of the lighting.

Moreover, the partition is embedded at the top of the reflecting unit30. Namely, the partition and the reflecting unit30are fitted together. The partition can be used to prevent external humidity, vapor, contaminants and foreign matters in the environment from entering the main body10. By this configuration, the present disclosure can use this design to make the interior of the main body10and the reflecting unit30airtight, further increasing the water proof and contaminant proof abilities of the light emitting diode lamp.

Furthermore, through the design of the reflecting unit30, the present disclosure can be applied on a traditional MR16 lamp fixture. Namely, the user can use the reflecting unit30independently and in conjunction with the MR16 lamp. By this configuration, the present disclosure can increase the applicability of the lamp system.

Second Embodiment

Referring toFIG. 2toFIG. 3, the second embodiment of the present disclosure provides a light emitting diode lamp system, including: a lamp and a control module40.

Its difference with the first embodiment lies in the light emitting diode lamp system, which in this case, further includes a control module40and a receiver103, for extending the application range of the light emitting diode lamp system. The heat sink20of the second embodiment of the present disclosure is the same as the heat sink described in the first embodiment, and therefore is not further described.

First, the main body10has a light emitting module101disposed in the main body10. The light emitting module101includes a first circuit board102, at least one light emitting element1020, a dynamic light adjustment module1010and a receiver103. The first circuit board102, the at least one light emitting element1020, and the dynamic light adjustment module1010share much similarity with their respective counterparts in the previous embedment, and therefore will not be reiterated further. The surface on the main body10opposite to the heat sink20has a circular groove serving as a light exit portion. The main body10can be made of metal or metal alloys, such as aluminum or aluminum alloys. The bottom of the circular groove of the main body10has a light scattering structure mainly for improving the light scattering ability of the light source. The light scattering structure can refract light from the light emitting element1020outwards, focusing them on a specific direction. However the present disclosure is not limited hereto.

Moreover, the control module40is disposed outside the main body10and is coupled to a power supply unit60. The control module40includes a second circuit board and multiple input units. The multiple input units include at least a dynamic light adjustment start key and a dynamic light adjustment stop key. When the user presses an input unit, a first-light-source control signal is produced and transmitted to the light emitting module101.

Then, the multiple input units can be multiple keys for pressing by external forces. Other than on/off keys, the input units can also include a dynamic light adjustment start key, a dynamic light adjustment stop key, brightness adjustment key and various types of preset scenario mode keys. Additionally, the control module40can further have a saving unit, for saving modes set by the users in a self-set mode.

Additionally, the control module40can include a case. The upper surface of the case has input unit for external forces to press on. An accommodating space is formed within the case. The first circuit board102is disposed inside the accommodating space, such as a remote control device. When the user presses the input unit, the control module40produces a first-light-source control signal, which can be transmitted wirelessly by infrared, radio or Bluetooth to a light emitting module101. However, the present disclosure is not limited hereto.

For example, when the user uses the light emitting module in lighting applications, the light emitting element1020drives at least a white light emitting diode chip according to the need of the user regarding brightness. When the user intends to adjust the light source emitted from the white light emitting diode, for example: warm colors, cool colors, at this moment, the color scheme can be adjusted by driving the light adjustment elements with the control module. When the user uses the light emitting module in non-lighting applications, at least one of the light adjustment element can be driven by the control module according to the need of the user regarding the light source color, thereby creating different light source colors.

Additionally, the light emitting module101further includes a receiver103for receiving the first-light-source control signals. When the light emitting module101receives the first-light-source control signal, differently colored light sources can be continuously created by controlling the blue light emitting diode chip1011, the red light emitting diode chip1012, the green light emitting diode chip1013, and the synchronous or asynchronous light emission of the light adjustment elements. Additionally, the receiver103can be an infrared, radio or Bluetooth wireless receiver. For example in the present embodiment, the receiver103is an infrared receiver. However, the present disclosure is not limited hereto.

Finally, the lamp of the present disclosure can further include a reflecting unit30same as the description in the first embodiment, therefore the reflecting unit30is not further described.

Its difference with the first embodiment lies in the light emitting diode lamp system, which in this case, further includes a control module40, a hub50and a receiver103, for extending the application range of the light emitting diode lamp system. The lamp of the third embodiment of the present disclosure is the same as the lamp described in the first embodiment, and therefore is not further described.

Moreover, the control module40is disposed outside the main body10and is coupled to a power supply unit60. The control module40includes a second circuit board and multiple input units. The multiple input units include at least a dynamic light adjustment start key and a dynamic light adjustment stop key. When the user presses an input unit, a first-light-source control signal is produced and transmitted to the light emitting module101.

Then, the multiple input units can be multiple keys for pressing by external forces. Other than on/off keys, the input units can also include a dynamic light adjustment start key, a dynamic light adjustment stop key, brightness adjustment key and various types of preset scenario mode keys. Additionally, the control module40can further have a saving unit, for saving modes set by the users in a self-set mode.

Additionally, the control module40can include a case. The upper surface of the case has input unit for external forces to press on. An accommodating space is formed within the case. The first circuit board102is disposed inside the accommodating space, such as a remote control device.

Finally, the main object of the receiver103is to receive the first-light-source control signal. When the receiver103receives a first-light-source control signal and transmits it to the light emitting module101, differently colored light sources can be continuously created by controlling the blue light emitting diode chip1011, the red light emitting diode chip1012, the green light emitting diode chip1013, and the synchronous or asynchronous light emission of the light adjustment elements. Additionally, the receiver103can be an infrared, radio or Bluetooth wireless receiver. For example in the present embodiment, the receiver103is an infrared receiver. However, the present disclosure is not limited hereto.

Finally, the lamp of the present disclosure can further include a reflecting unit30same as the description in the first embodiment, therefore the reflecting unit30is not further described.

Fourth Embodiment

Referring toFIG. 5, the fourth embodiment of the present disclosure provides a light emitting diode lamp system, including: multiple lamps, a control module40, multiple hubs50and a receiver103. A light emitting diode lamp system is formed by serial connection between a hub50and multiple hubs50.

Its difference with the third embodiment lies in a light emitting diode lamp system, in which the user can serially connect the hub50with multiple hubs50, thereby forming a light emitting diode lamp system, for broadening the range of application of the light emitting diode lamp system. The lamp, control module and receiver of the fourth embodiment of the present disclosure are similar to those described in the third embodiment, and therefore are not further described.

Finally, the lamp of the present disclosure can further include a reflecting unit30same as the description in the first embodiment, therefore the reflecting unit30is not further described.

Fifth Embodiment

Referring toFIG. 6, the fifth embodiment of the present disclosure provides a control method for a light emitting diode lamp system, including the following steps:

In step S10, first start a power supply unit60coupled to a hub50. In step S12, a receiver103electrically connected to the hub50receives a first-light-source control signal. In step S14, use the first-light-source control signal as a light source control signal for controlling at least one light emitting element1020and multiple light adjustment elements. In step S16, transmit the first-light-source signal to a microcontroller unit (MCU) disposed within the hub50, and compare the first-light-source signal with at least one program code in the microcontroller unit. In step S18, transmit a second-light-source control signal with a standard waveform to the hub50. In step S20, respectively control at least one light emitting element1020and multiple light adjustment elements to emit light by the electric current of the second-light-source control signal received by the hub50.

The main object of disposing a microcontroller unit within the hub50is to address the potential problem that, when the first-light-source control signal sent by the control module40, a long transmission distance or wide transmission angle leads to an altered or unrecognizable waveform of the first-light-source control signal after the first-light-source control signal received by the receiver103is decoded. More specifically, if the first-light-source control signal whose waveform is altered or unrecognizable is directly transmitted to multiple ports coupled to the hub50, the first-light-source control signal further attenuates due to signal distribution, resulting in abnormal operation of at least one light emitting element1020and multiple light adjustment elements.

Therefore, a microcontroller unit is disposed within the hub50for allowing the present disclosure to screen and filter waveforms, comparing every first-light-source signal with at least one program code in the microcontroller unit. When the waveform of the first-light-source control signal is partially altered or unrecognizable, the first-light-source control signal is not transmitted to the hub50. When the waveform of the first-light-source control signal can be recognized, a second-light-source control signal with a standard waveform is sent to the multiple ports of the hub50. The first-light-source control signal and the second-light-source control signal are similar, and the second-light-source control signal is built in the microcontroller unit.

It must be emphasized that in the present embodiment, due to the signal intensity of the second-light-source control signal sent by the microcontroller unit, the present disclosure serially connects multiple lamps in a system without suffering signal attenuation.
