The specific embodiment
Led light source of the present utility model comprises led light source chip 1, and described led light source chip 1 is arranged on the pedestal 2, and less than 90 °, described led light source chip 1 is arranged on the upper surface of described pedestal 2 greater than 0 ° for the upper surface of described pedestal 2 and the angle of lower surface.
Above-mentioned led light source chip can be single led light source chip, also can be the integrated encapsulation of a plurality of led light source chips.Above-mentioned led light source is that 1 light source chip 1 is arranged on 1 pedestal 2, can adjust the distribution of light so as required easily, makes led light source realize 0 °-180 ° scattering in three dimensions.
The utility model can directly be welded on led light source chip 1 on the pedestal 2, as shown in Figure 1, saved a conducting strip 3, simultaneously because led light source chip 1 directly contacts with pedestal 2, reduce the heat transfer medium of led light source chip 1 in diabatic process, improved heat transfer efficiency; The utility model also can be welded on led light source chip 1 on the conducting strip 3, and conducting strip 3 is installed on the pedestal 2 by card 4, as shown in Figure 2, perhaps is installed on the pedestal 2 by modes such as screw, rivets; The utility model can also be welded on led light source chip 1 on the conducting strip 3, and conducting strip 3 is embedded in 5 li of the grooves of pedestal 2, as Fig. 3, Fig. 4 and shown in Figure 5.
Above-mentioned conducting strip 3 can adopt aluminium base, copper base or other good thermal conduction and resistant to elevated temperatures material.Said base 2 can be passed through the Mould Machining moulding, pedestal 2 is cylinder preferably, can be cylinder, cuboid or other cylinder, and adopt material to make with good heat transfer capacity, but pedestal 2 is cylinder preferably, because pedestal 2 can rotate more neatly like this, adapt to luminous intensity distribution with different incline directions.
The installed surface that said base 2 is contacted with radiator 6 can be a plane, also can be the face of a band boss, as shown in Figure 6.Install when being connected when pedestal 2 and radiator 6, can dock with face by face, also boss can be mounted in the radiator 6, improved the contact area of pedestal 2 and radiator 6, help heat transfer, as Fig. 7, Fig. 8 and shown in Figure 9.When pedestal 2 is connected with radiator 6 installations, can connect by securing members such as screws.
LED light fixture of the present utility model, comprise led light source array and radiator 6, described led light source array is made up of led light source, described led light source comprises led light source chip 1, described led light source chip 1 is arranged on the pedestal 2, less than 90 °, described led light source chip 1 is arranged on the upper surface of described pedestal 2 greater than 0 ° for the upper surface of described pedestal 2 and the angle of lower surface, and described pedestal 2 is installed on the described radiator 6.
When led light source of the present utility model is integrated into the high-power illumination light fixture, can a plurality of pedestals 2 be installed on the radiator 6 according to different angles according to actual luminous intensity distribution needs; Also can be by the pedestal 2 and the radiator 6 of a plurality of different angles of processing mode one-shot forming such as die cast, as Figure 10, Figure 11 and shown in Figure 12.Led light source array of the present utility model not only can adopt planar array, as shown in figure 12, can also be the cambered surface array, as shown in figure 13, also can be annular array, as shown in figure 14.
Said base 2 is movably arranged on the radiator 6, can adopt modes such as bayonet socket, screw that pedestal 2 is movably arranged on the radiator 6, is convenient for changing the pedestal 2 of different angles like this.If the brightness in the actual measurement process on certain direction is not enough, can increase the light source on this direction again, or the unwanted led light source on certain direction replaced to the led light source that needs on the direction, just replace the pedestal 2 of different angles, thereby reach the purpose of targeted luminous intensity distribution.The utility model can be by changing upper surface and the angle of inclination of lower surface and the incline direction of pedestal of pedestal, can accomplish that each led light source has different angles, therefore because the flexibility of this luminous intensity distribution of the utility model can make led light source realize 0 °-180 ° scattering in three dimensions.
Embodiment 1:
As Figure 15 and shown in Figure 16, be the example that the utility model is used to be embedded in the formula Down lamp.The led light source chip is installed on the pedestal, form single light source module, again single light source module is installed by the mode of annular array and be positioned on the radiator, light direction is dispersed out with the form of certain angle, as shown in figure 17, this array way can reduce the too high problem of central point brightness, satisfies the uniformity and the uniformity of shadow surface, and the area of irradiation also is maximum.
Embodiment 2:
Shown in Figure 18 and 19, be that the utility model is used for the street lamp example, street lighting uses the lamp position generally than higher, and spacing is also bigger, in this example, by led light source being accomplished according to actual needs different inclination angles and when forming arrays and make street lamp, can being reached perfect light distribution effect according to different incline directions, satisfy fully that there are certain illumination and uniformity requirement in the road surface in the practical application, and to not influence of light extraction efficiency.If do not adopt this mode luminous intensity distribution, then can occur under the street lamp very brightly, the situation that other places are very dark perhaps adopts secondary lampshade luminous intensity distribution the situation that illumination descends to occur.
