Embodiment Construction

[0030] 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.

[0031] 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

An LED illumination device comprises a base, a drive device, a cooling cylinder, a connecting element, a rotary cylinder, a plurality of LED sub light sources and a plurality of cooling plates. The drive device comprises a motor and a gearbox. The cooling cylinder comprises a first cooling layer, a second cooling layer and a third cooling layer which are sequentially stacked. The rotary cylinder comprises a light-pervious layer, an adhesive layer and a projection layer which are sequentially stacked. The projection layer is provided with multiple projection parts. The edges of the cooling plates are connected with the third cooling layer. The cooling plates are sequentially arranged at intervals. The cooling plates are provided with air outlet holes. According to the LED illumination device, heat can be quickly dissipated to outside air in time, and cooling performance is good. Besides, the rotary cylinder comprises the light-pervious layer, the adhesive layer and the projection layer which are sequentially stacked so that the device can have a good illumination effect and artistic atmosphere. The LED illumination device is compact and simple in overall structure and suitable for being widely used and popularized.

Description

technical field [0001] The invention relates to the technical field of lighting, in particular to an LED 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 ou...
