Abstract
The invention provides a groove negative temperature cooling light-emitting diode (LED) pendant lamp with a pendant chain, and mainly solves the problems that an inductor of a power supply of an existing groove negative temperature cooling LED pendant lamp with a chain is large in calorific value and large in size, and an existing LED power supply circuit board is unreasonable in setting and inconvenient to install and maintain. The groove negative temperature cooling LED pendant lamp with the chain comprises an LED light source, an LED power supply, a pendant lamp shell and a pendant lamp shade. The LED power supply comprises a circuit board, a power pack body and a power pack cover. Installation and maintenance are convenient.
Description
technical field [0001] The invention relates to a recessed negative temperature heat dissipation LED pendant lamp with a hanging chain, which belongs to the field of LED lighting. Background technique [0002] LED lighting is light-emitting diode lighting, which is a semiconductor solid-state light-emitting device. It uses a solid semiconductor chip as a light-emitting material. In the semiconductor, the excess energy is released through the recombination of carriers to cause photon emission, and directly emits red, yellow, blue, green, blue, orange, purple, and white light. LED lighting products are lighting appliances manufactured using LEDs as light sources. [0003] The inductance of the LED power supply of the existing negative temperature heat dissipation LED chandelier with a hanging chain is generally wound with a thick wire (the wire diameter is generally greater than 1mm), which will lead to an increase in the skin effect of the inductance and a large inductance; ...
