Embodiment Construction

[0052] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0053] figure 1 An ultra-thin LED light engine 100 is shown, which includes a protective cover 106 , a driving circuit board 101 , an aluminum substrate 103 and at least one LED module 104 . As shown in the figure, the ultra-thin LED light engine 100 is facing upwards with a light emitting surface. Below is the aluminum substrate. The protective cover 106 is used to cover and protect the driving circuit board 101 to prevent external damage to the driving circuit board and to protect it from moisture and the like. The aluminum substrate 103 and at least one LED module 104 are closely attached to each other through the double-sided high-adhesive heat conduction sheet 102 .

[0054] The first surface of the aluminum substrate is covered by a double-sided high-adhesive heat conduction sheet 102 , and the driving circuit board 101 is fixed by means of the double-sided ...

Abstract

The invention relates to an ultrathin-type LED light engine (100) which comprises a protecting cover (106), a driving circuit board (101), an aluminum substrate (103) and at least one LED module (104). The first surface of the aluminum substrate is covered by a double-side high-viscosity heat conducting piece (102) so as to fix the driving circuit board (101), the LED modules (104) are fixed on the first surface and insulated from the aluminum substrate through an insulating layer (200) positioned on the first surface, an electroconductive line is arranged on the insulating layer and used for being electrically connected with the LED modules (104) and the driving circuit board (101), and size of the aluminum substrate is larger than that of the driving circuit board (101) on at least part of a peripheral outer-side area, so that the double-side high-viscosity heat conducting piece (102) positioned on the first surface at least fixes the protecting cover (106) locally. Ultrathin design is realized while internal integration of driving and controlling devices is realized; the double-side high-viscosity heat conducting piece is utilized, so that heat conducting is realized while a PCB (printed circuit board) and the protecting cover are fixed.

Description

technical field [0001] The invention relates to an integrated LED lighting device in the field of LED lighting, in particular to an LED light engine (Light Engine). Background technique [0002] LED light engine (LED light Engine) is an integrated light source that includes LED packaging components or LED arrays (modules), LED drivers, and other photometric, thermal, mechanical, and electrical components. The integrated light source can be connected directly to the branch circuit through conventional connectors that match LED luminaires. Therefore, the LED light engine is a device between the LED lamp and the LED light source. The difference from the LED light source is that it does not contain a standard lamp holder and cannot be directly connected to the branch circuit. The same point as the LED lamp is that it can have a set light distribution. and cooling function. This product can effectively improve the stability of LED indoor lighting and improve various performance...
