Fig. 1 is a schematic perspective view of a dual light source lighting device according to an embodiment of the present invention. As shown in the drawings, the dual light source lighting fixture 10 of the present invention mainly includes at least one first lighting device 11 and at least one second lighting device 13, wherein the second lighting device 13 is connected to the first lighting device 11. In the present embodiment, the number of the first lighting devices 11 may be one, and the number of the second lighting devices 13 may be two, and the first lighting devices 11 and the second lighting devices are respectively disposed on two sides of the first lighting device 11. Of course, the number of the first lighting devices 11 is one, and the number of the second lighting devices 13 is two, which is only one embodiment of the present invention and is not a limitation to the scope of the present invention.
The cob (chip On board) packaged led is a single module formed by directly bonding one or more led dies (Die) to a substrate or a printed circuit board, electrically connecting the led dies and the substrate or the printed circuit board by leads, and encapsulating the led dies and the substrate or the printed circuit board with resin.
The light-emitting diode packaged by the COB can be densely provided with a large number of light-emitting diode crystal grains in unit area, so that the light-emitting diode packaged by the COB is small in size, and the appearance after being electrified is more similar to a light-emitting plate rather than a plurality of independent light-emitting bodies. Therefore, the luminance of the COB-packaged LED is many times higher than that of the standard LED with the same area, and the defects of spot light and glare can be avoided. In addition, because the LED crystal grain is directly arranged on the substrate or the printed circuit board, the heat generated by the LED crystal grain in the light emitting process can be directly conducted to the radiator through the substrate or the printed circuit board, and the radiating efficiency can be improved.
Although the COB-packaged led has the above advantages and can increase the projection distance of the light source, the COB-packaged led still has the disadvantages of small light-emitting angle and small illumination area, and particularly, the COB-packaged led usually has the disadvantages of bright middle area and weak edge area when the light source illuminates the ground.
In the smd (surface Mount technology) packaged led, led dies are mounted on a conductive bracket or a carrier plate, and then the conductive bracket or the carrier plate on which the led dies are mounted is mounted on a substrate or a printed circuit board. Generally, the light source generated by the SMD led has the advantages of large light emitting angle (e.g. up to 120-. However, compared to the light emitting diode packaged in COB, the light emitting diode packaged in SMD has the disadvantages of lower heat dissipation efficiency and shorter projection distance.
Therefore, the present invention further provides a novel dual light source lighting fixture 10, which is provided with at least one first lighting device 11 and at least one second lighting device 13, wherein the first lighting device 11 comprises a first supporting base 111 and at least one first light emitting diode 113. Referring to fig. 2 and 4, the first light emitting diode 113 is disposed on the first supporting base 111, wherein the first light emitting diode 113 is a COB-packaged light emitting diode and is used to generate a first light source L1. For example, the light emitting diode die may be directly bonded to the first supporting base 111 through a thermal conductive adhesive, or the light emitting diode die may be bonded to the first supporting base 111 through a thermal conductive substrate, so as to form a COB-packaged light emitting diode.
In addition, the second lighting device 13 includes a second supporting base 131 and a plurality of second light emitting diodes 133, wherein the second light emitting diodes 133 are disposed on the second supporting base 131. The second led 133 is an SMD packaged led and is used to generate a second light source L2. For example, the led die may be disposed on the conductive support or the carrier plate, and the conductive support or the carrier plate is bonded to the second support 131 through the thermal conductive adhesive, or the conductive support or the carrier plate is bonded to the second support 131 through the thermal conductive substrate, so as to form an SMD packaged led.
Since the first led 113 is a COB-packaged led and the second led 133 is an SMD-packaged led, the first light source L1 generated by the first lighting device 11 and/or the first led 113 is different from the second light source L2 generated by the second lighting device 13 and/or the second led 133, wherein the projection distance D1 of the first light source L1 is greater than the projection distance D2 of the second light source L2, and the light emitting angle and/or the irradiation area a2 of the second light source L2 is greater than the light emitting angle and/or the irradiation area a1 of the first light source L1.
The utility model discloses a two light source illumination lamps and lanterns 10 can produce the first light source L1 and the second light source L2 that have different characteristics simultaneously for two light source illumination lamps and lanterns 10 can have longer throw distance and great luminous angle and/or shine the area simultaneously.
In an embodiment of the present invention, the dual light source lighting fixture 10 may have a first lighting device 11 and a plurality of second lighting devices 13, wherein the plurality of second lighting devices 13 are disposed around the first lighting device 11. Through the above design, the light source generated by the dual light source lighting fixture 10 has a better light-gathering effect and a longer projection distance in the middle area, and has a larger light-emitting angle and/or irradiation area around, thereby increasing the lighting effect and the applicable range of the dual light source lighting fixture 10.
In an embodiment of the present invention, as shown in fig. 3, the first illumination device 11 may include a first lamp cover 115, and the second illumination device 13 may include a second lamp cover 135, wherein the first lamp cover 115 and the second lamp cover 135 are made of a material with light-transmitting property. The first cover 115 is connected to the first support base 111 and covers the first led 113, and the second cover 135 is connected to the second support base 131 and covers the second led 133. The first light emitting diode 111 on the first lighting device 11 and the second light emitting diode 131 on the second lighting device 13 can be further protected by the first lamp cover 115 and the second lamp cover 135.
In addition, the first lampshade 115 and the second lampshade 135 can be respectively provided with a first pattern 117 and a second pattern 137, and the refraction angles of the first light source L1 and the second light source L2 can be further changed by the first pattern 117 and the second pattern 137, for example, the first pattern 117 is different from the second pattern 137. Specifically, the first pattern 117 may further focus the first light source L1 to increase the projection distance of the first light source L1, and the second pattern 137 may diverge the second light source L2 to increase the illumination angle and/or the illumination area of the second light source L2. For example, the first motif 117 may be a pattern of concentric circles, while the second motif 137 may be a grid-like pattern. Of course, the first pattern 117 is only an embodiment of the present invention for focusing the first light source L and the second pattern 137 is only an embodiment of the present invention for diverging the second light source L2, and the scope of the present invention is not limited thereto.

In an embodiment of the present invention, the first lighting device 11 can be provided with two first connecting portions 119, and the number of the second lighting devices 13 is two, and the two first connecting portions 119 of the first lighting device 11 are respectively connected, for example, the two first connecting portions 119 are respectively disposed on two opposite sides of the first lighting device 11, so that the second lighting devices 13 are respectively disposed on two opposite sides of the first lighting device 11. Of course, in different embodiments, the number of the first connecting portions 119 may be two or more, and two or more second lighting devices 13 may be connected to the first lighting device 11.
In practical applications, the second lighting device 13 can be rotated relative to the first lighting device 11 to change the projection angle or direction of the second light source L2. For example, when two second lighting devices 13 are disposed on both sides of the first lighting device 11, one of the second lighting devices 13 may rotate clockwise around the first rotating shaft 171, and the other second lighting device 13 may rotate counterclockwise around the first rotating shaft 171. By the design of the above mechanism, the projection angle or direction of the second light source L2 can be changed, and the irradiation area and projection area of the light source generated by the dual light source lighting fixture 10 can be further increased.

Specifically, the axes of the first rotating shaft 171 and the second rotating shaft 173 are approximately perpendicular, so that the dual-light source lighting fixture 10 can flexibly adjust the projection angle and direction of the light source. For example, the first illumination device 11 and the second illumination device 13 can swing up and down with respect to the base 15 with the second rotation shaft 173 as the axis, and the second illumination device 13 can swing left and right with respect to the first illumination device 11 with the first rotation shaft 171 as the axis.
