As shown in fig. 1, a schematic overall view of a color temperature tunable LED luminaire according to an embodiment of the present invention, which may be used as a step lamp, is schematically illustrated. Fig. 2-3 schematically show exploded views of the color temperature adjustable LED lamp. As shown in fig. 1 to 3, the LED lamp includes a lamp housing 10 as a mounting base and an LED driving-light source module 20 detachably mounted on the lamp housing 10 by, for example, screws 21. The LED driving-light source module 20 integrates an LED driving (and adjusting) circuit and a light source, etc., which is mounted on the lamp housing 10 having a flat base, and has a generally elongated (e.g., square column) shape. The LED lamp with the shape is suitable for being installed at a step part, commonly called a step lamp, and can be applied to indoor or outdoor, in particular to outdoor landscape lighting.
The LED driving-light source module 20 of a generally elongated (e.g., square column) shape includes a generally rectangular bottom cover 41 with a sealing gland 40 mounted thereon, a PCB circuit board 42 mounted on the bottom cover 41, and an upper case 45 of, for example, plastic form fastened to the circuit board 42 and the bottom cover 41. The PCB circuit board 42 is provided with electronic circuits, LED light sources 43 and other electronic components for driving and controlling the LEDs, and in particular for color temperature regulation in the present application.

Also, the upper case 45 is preferably recessed at a portion corresponding to the LEDs 43 arranged on the circuit board 42, preferably a flat recessed section connected to the adjacent upper case 45 by a slope, as shown in fig. 1 to 3. Underneath the upper case 45, a silicone pad 44 for sealing water-proof may be provided between it and the PCB circuit board 42, as shown in fig. 3.
The LED driving-light source module 20 and the color temperature adjusting key 30 mounted thereon are described below.
As shown in fig. 1 to 6, an opening is provided in the top cover of the upper case 45 of the LED driving-light source module 20, and the color temperature adjusting key 30 is disposed in the opening so as to be sunk. As shown in fig. 3, the color temperature adjusting key 30 sequentially includes, from top to bottom, a key handle 31 for manipulation, a waterproof rubber pad 32 such as a silica gel pad for waterproof sealing to provide waterproof sealing performance and weather resistance to the LED lamp and the key 30, and a button 33 such as a patch type button surface-mounted on a PCB circuit board 42, for example. Thus, by operating the push button handle 31, the button 33 is indirectly pushed, so that the push button 30 is operated, and color temperature adjustment is realized as described below.
In the lamp housing 10, the waterproof junction box 13, the plastic bottom cover 14 thereof and the electric wires 16 can be mounted and fixed on the bottom shell 15 of the lamp housing 10 by screws 11. The bottom cover 41 and the PCB circuit board 42 are mounted and fixed on the bottom case 15 with screws 25 at the top of the waterproof terminal box 13, wherein the power pins 12 are electrically connected to the wires 16 inputted from the external power source in the waterproof terminal box 13 and electrically connected to the wiring board 22 (the wiring board 22 may be electrically connected to the PCB circuit board 42 by wires or wirings/lines, for example) arranged/mounted on the circuit board 42 by electrically conductive connection pins such as the pogo pins 23, and the pogo pins 23 are preferably covered with waterproof rubber sleeves 24 such as silicone sleeves, as shown in fig. 4, so as to provide waterproof sealing for the circuit board. The conductive connection pins 23 are preferably in the form of pogo pins to ensure good, reliable conductive contact with the power pins 12.
Fig. 5-6 illustrate the assembly of the components of the LED light fixture. The LED driving-light source module 20 is placed on the bottom case 15 of the lamp housing 10 as a mounting base, one end of the LED driving-light source module 20 abuts against an end side 151 of the lamp housing 10, and a catching position 152 (shown as protruding from the outside toward the LED driving-light source module 20) on the end side 151 is caught in a concave catching position 451 at the end of the LED driving-light source module 20, forming a catching fit, and thereby fixing the LED driving-light source module 20 at one end. At the other end of the LED driving-light source module 20, after the pogo pins 23 on the LED driving-light source module 20 are aligned with the power pins 12 and are inserted and assembled, screws 21 are passed through the LED driving-light source module 20 and the mounting holes aligned with each other on the lamp housing 10 and are tightened, thereby completing the assembly of the LED lamp. When the LED lamp is disassembled, the LED drive-light source module 20 can be easily pulled out from the lamp housing 10 after the screw 21 is loosened.
Examples of color temperature Regulation
One embodiment of color temperature regulation of the color temperature tunable LED lamp of fig. 1-6 is described below in connection with fig. 7-8. Fig. 7 is a schematic diagram of adjusting the color temperature of LED light using the native color temperature adjustment key of fig. 1-6 according to an embodiment of the present invention. Fig. 8 is a schematic circuit diagram of the embodiment of fig. 7 for adjusting the color temperature of LED light using a color temperature adjustment key native to the LED luminaire.
As shown in fig. 7-8, the trigger signal is provided to the micro controller unit MCU of the LED luminaire by pressing the color temperature adjustment key 30 once (i.e. turning on/off the circuit once). The memory of the MCU can be set (burned) with the ratio combination of the working currents of the LEDs with different color temperatures (for example, the LED with two different color temperaturesIn the case of light mixing, x% I 0 +y％I 0 Wherein I 1 An operating current for the LED light of the first color temperature, I 2 The values of x and y can be arbitrarily set as needed for the operating current of the LED light of the second color temperature, as long as x+y=100 is ensured. For example, after the first pressing, the micro controller unit MCU receives the trigger signal and controls the branch circuit to output the working current x of the primary current proportioning combination according to the setting 1 ％I 0 +y 1 ％I 0 Thus, the LED mixed light with the first color temperature is obtained. After the second pressing after the first pressing, the micro controller unit MCU receives the trigger signal and controls the branch circuit to output working current x combined according to different current ratios 2 ％I 0 +y 2 ％I 0 Thereby obtaining a second color temperature of the LED mix. The first and second presses may be one cycle period according to the setting of the MCU; the third and fourth presses are considered to be the next cycle, the color temperature is output according to the settings of the first and second presses, and so on.
Of course, according to the setting of MCU, the microcontroller MCU can also set and output the working current x of the third different current proportion combination after the third pressing after the second time 3 ％I 0 +y 3 ％I 0 The LED light mixture of the third color temperature is thus obtained and can be set such that one complete cycle is constituted by the first, second and third presses. Alternatively, more different current ratios and different cycle periods may be similarly set, and so on.
Therefore, although the present invention has been described in more detail by way of the above embodiments, the present invention is not limited to the above embodiments, but the inventive concept in the summary of the present invention, the above embodiments, and the above alternative embodiments and concepts fall within the scope of the present invention. Many other equivalent embodiments may be made without departing from the spirit of the invention, the scope of which is determined by the scope of the appended claims.
