As shown in fig. 2, 3, and 7, in the present invention, preferably, a distance is provided between two adjacent circles of the LED strip 5 wound on the heat conducting tube 4, that is, when the LED strip 5 is wound on the outer circumferential surface of the heat conducting tube 4, the LED strip does not completely cover the outer circumferential surface of the heat conducting tube 4, but a distance is provided between two adjacent circles of the spiral structure formed by the LED strip 5, so that the heat dissipation capability of the heat conducting tube 4 can be improved, and a good air flowing space is provided for the air flowing in the air hole 41 on the heat conducting tube 4.
When the full-color-domain LED balloon lamp provided by the invention is used, the fan 3 firstly works at full speed to inflate the balloon lamp, the LED lamp beads start to have 10% brightness after 5 seconds, after a period of time, the balloon cloth cover 1 expands to a working state, the balloon cloth cover 1 is filled with gas, then the fan 3 can reduce the speed to 20% to operate and enter an air-supplementing mode, at the moment, the gas in the balloon cloth cover 1 is exposed through the air holes in the balloon cloth cover 1, the air is supplemented by the fan 3, so that the balloon cloth cover 1 is always in the state of being filled with the gas, and meanwhile, the heat in the heat-conducting cylinder 4 can be taken away through the air supplementation, so that the LED lamp beads are at normal working temperature.
The panchromatic LED balloon lamp can be applied to illumination of large studios, photostudio canopies and the like, the irradiated light field is uniform, the shadow is pure, the effect is natural, and the illumination requirement of professional photography can be met by light rays in the rooms and the canopies; the LED lamp strip 5 is matched with a special heat dissipation structure to replace a traditional metal halide bulb, so that the energy of the lamp can be saved by more than 80%; by arranging the heat conducting cylinder 4 and winding the LED lamp strip 5 on the outer wall of the heat conducting cylinder 4, heat generated by the LED lamp strip 5 can be quickly conducted to the heat conducting cylinder 4 and can be taken away by airflow flowing through the heat conducting cylinder 4; the wall of the heat conducting tube 4 is provided with the plurality of uniformly distributed air holes 41, so that a space is formed between two adjacent circles wound on the LED lamp strip 5, the heat dissipation effect of the LED lamp strip 5 can be further improved, and the LED lamp strip 5 is ensured to be in a normal working temperature range; through setting up red, green, blue, cold white and warm white five LED lamp pearls, can satisfy the occasion of different colour temperatures and luminance demands to the illuminating effect is superior to the LED lamps and lanterns of present general use on the market.
The sequence of the above embodiments is only for convenience of description, and does not represent the merits of the embodiments.
Finally, it should be noted that: the above embodiments are only for illustrating the technical solutions of the present invention, and not for limiting the same; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may be modified or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
