Example Embodiment

[0016] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the following further describes the present invention in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention.

[0017] Such as image 3 , 4 As shown, the LED spotlighting lamp of the present invention includes a reflector 1 and an LED 2 arranged in the reflector 1. The reflector 1 is a parabolic reflector, and the equation is y 2 =16X; LED2 is set on the focal point of reflector 1. A lens 3 is arranged in front of the LED2, and the lens 3 is arranged in a lens holder 4 that can be moved and adjusted along the main optical axis of the LED. The lens holder 4 includes a base 5 and a plurality of support columns 6, one end of the support column 6 is fixedly connected with the lens 3 Its other end is fixed o...

Abstract

The invention provides an LED light focusing and flooding lamp which is suitable for the fixed or the movable illumination of the electric torch, the head lamp and the like. The LED light focusing and flooding lamp comprises a reflector (1) and an LED (2), wherein the LED (2) is arranged in the reflector (1), the front of the LED (2) is provided with a lens (3), and the lens (3) is arranged on an adjustable lens support (4) which can move along the main optical axis of the LED (2). When focusing the light, the LED light focusing and flooding lamp can ensure that the center of the light spot has high light intensity and high luminous flux utilization ratio, and when flooding the light, the LED light focusing and flooding lamp can ensure that no dark spot appears in the center of the light spot and the illumination of the light spot in the center is uniform.

Description

technical field [0001] The invention relates to an LED lamp, in particular to an LED lamp with adjustable spotlight and floodlight. Background technique [0002] As an energy-saving and environmentally friendly light source, LED has been widely used in spotlights such as flashlights and headlights. At the same time, fixed floodlights and movable floodlights are also constantly developing and improving, but lamps with two functions of spotlight and floodlight and adjustable spot size are relatively rare, and the only spotlights on the market are relatively simple. , the luminaire is composed of LEDs with a parabolic reflector, where the position of the reflector can be adjusted to switch between spotlight and floodlight. Such as figure 1 As shown, the working principle of this kind of focusing floodlight is that the LED light source is placed at the focus of the parabolic reflector, and the light emitted by the LED light source is emitted by the parabolic reflector and exit...
