Problems solved by technology

The normal working temperature of LED is usually between -20℃+60℃. Due to its insufficient heat dissipation capacity, if no auxiliary heat dissipation is performed, the performance of LED decorative lights will deteriorate; the heat generated by LED decorative lights cannot be dissipated in time. The accumulated heat will also affect the service life of LED decorative lights
[0003] At present, one of the heat dissipation methods for LED decorative lights is to pour silicone on the outside of the LED module, drive power supply and other heat-generating components. Since the external silicone is soft, it is easy to be damaged and polluted, and the silicone is close to the LED module. Finally, because the refractive index of silica gel to light is different from that of air, the color temperature and color of light will change, resulting in unstable luminous color of the LED module.
[0004] In summary, although the heat dissipation structure of LED decorative lights in the prior art has a heat dissipation effect, it has many negative effects on the luminous performance of LED decorative lights

Abstract

The invention relates to an LED decorative lamp, and belongs to the technical field of lighting equipment. The provided LED decorative lamp comprises an LED module, a power module and a bulk which isarranged outside the LED module and the power module. The LED module includes a light emitting part and a non-light-emitting part arranged outside the light emitting part, and the LED module is electrically connected with the power module; the LED decorative lamp further includes a radiator. The radiator includes an accommodating chamber and a heat conduction part. The power module is arranged inthe accommodating chamber. The heat conduction part of the radiator is connected with the non-light-emitting part of the LED module. As the radiator is connected with the non-light-emitting part of the LED module, the light emitting effect of the LED module is not affected when the LED module is cooled.

Description

technical field [0001] The invention relates to an LED decorative lamp, which belongs to the technical field of lighting equipment. Background technique [0002] LED modules are widely used in G4, G9 and other decorative lights because of their large luminous angle and uniform luminous color to meet the requirements of the luminous angle. However, LED decorative lights generate heat when in use. The normal working temperature of LED is usually between -20℃+60℃. Due to its insufficient heat dissipation capacity, if no auxiliary heat dissipation is performed, the performance of LED decorative lights will deteriorate; the heat generated by LED decorative lights cannot be dissipated in time. The accumulated heat will also affect the service life of LED decorative lights. [0003] At present, one of the heat dissipation methods for LED decorative lights is to pour silicone on the outside of the LED module, drive power supply and other heat-generating components. Because the sil...
