Embodiment Construction

[0013] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0014] refer to figure 1 and figure 2 , propose an embodiment of the LED light source device of the present invention:

[0015] An LED light source device includes a backing plate 10, an LED driver 12 and an LED light source board 11. The LED light source board 11 and the LED driver 12 are installed on the backing board 10 to form an LED light source device. There are three LED light source boards 11. The LED light source board 11 is composed of LED substrates and LED chips. The LED driver 12 is installed at the center of the backing plate 10 , and the LED light source boards 11 are evenly distributed around the LED driver 12 . The fan-shaped LED light source board 11 is distributed around the backing plate 10, so that the LED chips are scattered on various positions of the backing plate, the light distribution is...

Abstract

The invention discloses an LED light source device. The LED light source device comprises a cushion plate, an LED driver and an LED light source plate; the LED light source plate and the LED driver are installed on the cushion plate, the overall LED light source device is formed, and overall installing and overall replacing are facilitated. An LED substrate is provided with a plurality of through holes in which magnets are embedded, the upper end face of the LED substrate is provided with a fixing piece made from magnetic metal, the fixing piece covers the through holes, and the fixing piece and the magnets are mutually attracted magnetically; and the cushion plate is made from magnetic metal, the LED substrate is attracted to the cushion plate through the magnets, and installation is convenient. A non-polar thin-film capacitor C2 quite small in capacity is adopted for a driving circuit built in the LED driver to replace an electrolytic capacitor, the thin-film capacitor C2 is the same as the electrolytic capacitor in filtering effect, the thin-film capacitor C2 is good in stability, extremely high in anti-interference capacity and high in reliability, and the service life of a power source is greatly prolonged.

Description

technical field [0001] The invention relates to the field of LED lighting, in particular to a conveniently assembled LED light source device. Background technique [0002] At present, LEDs are gradually replacing incandescent and fluorescent light sources with their long life, no pollution, and high luminous efficiency. The LED chips in existing LED lamps are all installed on the substrate used to carry the LED chips to form an LED light source board. In LED lamps, the LED light source board and the LED driver need to be installed one by one, and the connection wire between the LED light source board and the LED driver is exposed, and it is easy to be pulled during installation, which will lead to open welding. Contents of the invention [0003] The main purpose of the present invention is to provide an LED light source device in which the LED light source board and the LED driver are connected as one, which is convenient for installation. [0004] The present invention p...
