Embodiment Construction

[0012] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0013] see Figure 1-2 , shows a cross-sectional view and a top view of the light bar 10 of the present invention. The light bar 10 is in the shape of a long strip. The light bar 10 includes a strip substrate 20 and a plurality of LEDs 30 . The LEDs 30 are uniformly arranged on the substrate 20 . The substrate 20 includes a first metal layer 21 , an insulating layer 22 and a second metal layer 23 . The first metal layer 21 , the insulating layer 22 , and the second metal layer 23 are stacked sequentially from top to bottom. The first metal layer 21 and the insulating layer 22 are bent vertically at both ends of the light bar 10 , the insulating layer 22 covers the second metal layer 23 , and the first metal layer 21 covers the insulating layer 22 on the outermost side. Wherein, the first metal layer 21 is in direct contact with the LED 30 . The thickness of the...

Abstract

The invention relates to an LED (light emitting diode) lamp strip which comprises a baseplate and a plurality of LEDs arranged on the baseplate, wherein the surface of the baseplate avoids the positions of the LEDs to form a rough surface so as to increase a heat dissipation area. The LED (light emitting diode) lamp strip provided by the invention has the advantages that the heat dissipation area of the surface of the baseplate is increased, the baseplate can rapidly emit heat into air, and the LED lamp strip obtains a better heat dissipation effect.

Description

technical field [0001] The invention relates to an LED light bar, in particular to an LED light bar with better heat dissipation effect. Background technique [0002] The LED industry is one of the industries that has attracted the most attention in recent years. Up to now, LED products have the advantages of energy saving, power saving, high efficiency, fast response time, long life cycle, mercury-free, and environmental protection benefits. Used for lighting purposes. However, the heat dissipation problem of LED affects the efficiency of LED to a great extent. Poor heat dissipation will directly shorten the life of the LED or even make the LED lamp scrapped. Therefore, it is necessary to dissipate heat from the LED. However, due to the packaging limitation of the LED light bar, heat dissipation of the LED light bar has always been a key issue in the research of the industry. Contents of the invention [0003] In view of this, the present invention provides an LED lig...
