Embodiment Construction

[0028] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0029] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of ill...

Abstract

Disclosed is an illuminating device. The illuminating device comprises a base, a rotating device, a radiating barrel, fixing parts, a rotating barrel, multiple light-emitting diode (LED) auxiliary light sources and multiple radiating columns. The rotating 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 side surface, far from the adhesive layer, of the light transmitting layer is fixedly connected with the second end of the corresponding fixing part, and the projection layer is provided with multiple projection parts. The ends of the multiple radiating columns are arranged on the third radiating layer, each radiating column is of a hollow structure, and multiple vent holes are formed in the radiating columns. By means of the illuminating device, heat generated by the LED auxiliary light sources can be rapidly and timely radiated to outside air, and the radiating performance is good. 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.

Description

technical field [0001] The invention relates to the technical field of lighting, in particular to a lighting device. 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 tha...
