lighting device

Abstract

Disclosed is illumination equipment. The illumination equipment comprises a base, a driving device, a radiating barrel, connecting parts, a rotating barrel, a plurality of light-emitting diode (LED) auxiliary light sources and a radiating pipe. The driving device comprises a motor and a speed changing box. The radiating barrel comprises a first radiating layer, a second radiating layer and a third radiating layer which are sequentially overlaid. The rotating barrel comprises a light transmitting layer, an adhesive layer and a projection layer which are sequentially overlaid. The projection layer is provided with a plurality of projection parts. The radiating pipe is provided with a regular polygon cross-section structure, multiple end angles of the radiating pipe are connected with the third radiating layer, and a radiating channel is defined by the side surface of the radiating pipe and the third radiating layer. By means of the illumination equipment, heat generated by the LED auxiliary light sources can be rapidly and timely radiated to outside air, and the radiating performance is good. Besides, the rotating barrel comprises the light transmitting layer, the adhesive layer and the projection layer which are sequentially overlaid, and the good illumination effect and artistic atmosphere can be achieved. The illumination equipment is simple and compact in the whole structure and suitable for being widely applied and popularized.

Description

technical field [0001] The invention relates to the technical field of lighting, in particular to lighting equipment. Background technique [0002] At present, because LEDs can directly and efficiently convert electrical energy into visible light, and have a service life of tens of thousands of hours to 100,000 hours, and have the advantages of energy saving, LED lamps made of LEDs are characterized by high quality, durability, and energy saving. And other advantages and is used as the most commonly used lighting fixtures. Usually, the basic structure of an LED is a semiconductor P-N junction. When the current flows through the LED element, the temperature of the P-N junction will rise, and the temperature of the P-N junction area is called the junction temperature of the LED. Usually due to The component chips all have a very small size, therefore, the temperature of the LED chip is also called the junction temperature of the LED chip. [0003] It should be pointed out th...
