Energy-saving LED strong light device

Abstract

The invention discloses an energy-saving LED strong light device comprising a base plate, an LED, a light source reflection bowl, a radiator and a translucent lampshade. The energy-saving LED strong light device has the main technical points that connected light source reflection bowl structures are evenly distributed on the convexity of an arc-shaped heat conduction base plate, the inner side of each light source reflection bowl is provided with an LED, the back end part of the LED is connected with the arc-shaped heat conduction base plate, and the edge of the light source reflection bowl structure is convex honeycomb-shaped structure; the radiator is arranged on the concavity of the arc-shaped heat conduction base plate; a power supply driving controller is connected between the LED and the power supply which are connected in series; the power supply driving controller respectively comprises a limited current circuit, a voltage doubling rectifying circuit and a constant current circuit, wherein the voltage doubling rectifying circuit is connected with the output end of the limited current circuit, and the constant current circuit is connected with an output end of the voltage doubling rectifying circuit. As all LEDs in a lamp are connected in series, the constant current circuit provides stable output current for LEDs connected in series, which relatively improves the service life of the LEDs. The invention also has the characteristics of safety, reliability, wide application range and the like.

Description

technical field [0001] The invention relates to the technical field of lighting, in particular to an energy-saving LED strong light device. Background technique [0002] As we all know, with the continuous development of semiconductor technology, LED semiconductor light source, as an energy-saving light source, has gradually been valued by government departments at all levels, and has a small amount of application in street lamp or spotlight lighting, and has become a lighting source after incandescent lamps and fluorescent lamps. The third generation of lighting sources after lamps. However, the characteristics of high-power LED light sources require that the heat generated by the LED light source must be exported in time during work; because the distribution of the LED light source is relatively small, it is necessary to carry out secondary optical design for the light source to avoid excessive concentration of LED street lights or spotlights; in addition, Since the curre...

However, the characteristics of high-power LED light sources require that the heat generated by the LED light source must be exported in time during work; because the distribution of the LED light source is relatively small, it is necessary to carry out secondary optical design for the light source to avoid excessive concentration of LED street lights or spotlights; in addition, Because the current of the external power supply cannot be kept constant due to various reasons, the fluctuation of the current will also cause the temperature rise of the electrical components. The above three problems have now become the bottleneck of the development of LED light sources in street lamps or spotlights.
