New description: [New technical field] This creation is a light-emitting diode device, especially a light-emitting diode device with low heat consumption. [Prior Art] Please refer to Fig. 1 'Fig. 1 is a schematic view of a conventional light-emitting diode device. The conventional light-emitting diodes are mostly connected in parallel with a plurality of light-emitting diode strings 11 and in parallel with a power supply 10#, wherein the power supply 10 can be an AC voltage source or a DC voltage source, each of which emits light. The diode lamp string 11 is composed of a plurality of light-emitting diodes connected in series, and the power supply is a low-voltage supply power source, and the voltage is usually between 6 and 24 volts. Since all of the light-emitting diode strings 11 receive the same voltage in parallel, the current of the light-emitting diodes in the light-emitting diode strings 11 at the same voltage is different due to the discreteness of the manufacturing process, resulting in the respective light-emitting diodes. The luminosity varies, although the same type of LED will have a similar brightness', but the parallel application is unsatisfactory due to fluctuations in the production process. Therefore, most manufacturers of LED devices will The LED array 11 is connected with a certain current • The source 12 (also referred to as a constant current source) 'to stabilize the current flowing through each of the LED strings 11 to precisely control the LEDs. Luminous brightness. However, the above-mentioned plurality of constant current sources 12 are arranged to control the LED strings u in addition to the improvement of the manufacturing cost, and the constant current sources 12 additionally generate a large amount of heat energy due to power consumption; the problem of heat dissipation is directly It affects the brightness of the light-emitting diodes. If it is serious, it will greatly reduce the service life of the light-emitting diodes. Therefore, the creator has in view of the fact that the current LED device will generate high heat in the use of 3 '-, is a painstaking research and design system to provide (4) the use of the public, for the creative work of the creative By. [New Content] With the above-mentioned lacks and creative motives, the creator has made every effort to develop this creation. The creation of the present invention is to provide a light-emitting diode device that is connected to a reduced current heat source through a single-constant current source to overcome multiple conventional sets of constant current sources to control multiple sets of parallel light-emitting diode strings. And cause heat loss problems. According to an embodiment of the present disclosure, a light emitting diode device includes a rectifying voltage regulator, and at least one light emitting diode string and at least a constant current module. The rectifier voltage regulator module is electrically connected to the -mains f source and converts the mains-acoustic voltage (A-g. gamma AC voltage) into a DC drive voltage. The light-emitting diode lamp string has a first end and a second end, and is formed by a plurality of light-emitting diodes connected in series, and the first end of the light-emitting diode light string is electrically connected to the rectifying and regulating mode The group is configured to receive a DC driving voltage, and the constant current module is electrically connected between the rectifying voltage regulator module and the second end of the LED string, and provides a stable DC current to drive the LED according to the DC driving voltage. The body light string emits light. The number of the light-emitting diodes corresponds to the magnitude of the AC voltage of the commercial power source in a proportional relationship. Therefore, according to the structure disclosed above, the light-emitting diode device of the present invention is configured to emit a light-emitting diode according to a corresponding number of current sources, so that the light-emitting diode string can be driven by a single current source, except for circuit design. In addition to the advantages of being simple and having a lower cost, the light-emitting diode device designed by a plurality of conventional constant current sources also has less heat energy generation and lower work M414047. The electromagnetism of the gate of the TR body has the effect of voltage regulation, so that the gate voltage can be fixed at a specific size. [4] The person knows that when the _pressure is fixed, the bungee is The increase of the source _ will increase the driving electron crystal emission, and the voltage between the secret source and the source and the current of the enemy and the secret current will be secretive _, and the output effect of the constant current is corrected. In addition, please refer to Fig. 4, which is a schematic view showing another embodiment of the present light-emitting diode device. In order to make the single-light dipole view have a high flow of the lungs,
