Embodiment

The utility model provides a kind of new LED supporting structure, and it comprises the LED bearing with certain altitude.Can also comprise two metal legs, and LED bearing and two metal legs fix with insulator, further comprise the transparent Lamp cup that chip is outer, and Lamp cup is outer or inner bottom part is provided with the rear-mounted laser reflecting piece in plane.

With reference now to Fig. 1, an embodiment of the present utility model is described.Fig. 1 is the front view according to the supporting structure of the utility model preferred embodiment.Be placed with led chip 1 on the led support structure of this embodiment, this direct organization also comprises transparent Lamp cup 3, LED bearing 2, two metal legs 4, insulator 5 and the radium-shine reflector layers 33 of transparent flat.

LED bearing and two metal legs all are good and have the metal of certain mechanical strength by heat conductivility, and at the top of LED bearing fixed L ED chip 1.LED bearing and two metal legs are connected and fixed with insulator 5, and led chip 1 is electrically connected on two metal legs 4 of support by welding, select both positive and negative polarity to be connected on the circuit again, and then form the power supply passage.

At least one transparent Lamp cup 3 is set on each support.Lamp cup 3 can adopt material transparent, and for example PC material (being Merlon) or polymer are made.According to the needs of light efficiency, also can adopt ground glass or translucent other plastic materials to make various difform Lamp cups 3, with the soften of increase light and the aesthetics of LED lamp.Outer or the inner bottom part of Lamp cup is provided with the rear-mounted radium-shine reflecting piece in plane, improving the reflection of light, thereby increases luminosity.Because the characteristic of radium-shine processing, irradiate light changes the part colour temperature behind reflective surface, can reduce the stimulation of direct-view light to eyes.

As can be seen from Figure 1, below Lamp cup 3, also be provided with insulator 5, fixed by described insulator 5 thereby LED bearing and two metal legs pass this insulator 5.This insulator is the insulating material with certain degree of hardness, to play effect fixing and support LED bearing and two metal legs.Fig. 4 has shown the set-up mode of led chip in detail, wherein led chip 1 is set on the intermediate studdle 2 that protrudes from Lamp cup base plane certain altitude h, described height h can be designed to approximately between the 1.2-3mm, thereby make chip increase to about 270 ° of up by about 180 ° to the angle of spatial emission light, this has not only increased irradiating angle, and has ensured the mean intensity of illumination better.Refer again to Fig. 1, be applied with transparent mixture 14 in the Lamp cup 3, be used to protect luminous element 1 and bonding line 20.Support is connected with other element by screw hole 8, cooperates to form stable the connection.
