Embodiment Construction

[0028] The preferred embodiments of the present invention will be described in detail below with reference to the drawings.

[0029] The structure of the LED lamp of the embodiment of the present invention is as follows: figure 2 As shown, it includes an LED light source 22 and a reflector 21 , wherein the reflector 21 is composed of a reflector body 23 and a reflective layer arranged on the inner side of the reflector body 23 . The radial cross-sectional inner boundary line of the reflector body 23 is a curve, such as image 3 shown. The curve includes two axisymmetric parabola segments, the tail ends of the two parabola segments are connected, and the starting ends are respectively bent inward through the meander line, wherein the inward bending points to the side of the reflective body provided with the reflective layer. fold. In this embodiment, the end of the parabola segment 231 closest to the origin is the starting end, and the far end is the tail end, such as Fig...

Abstract

The present invention relates to an LED lamp which comprises an LED light source and a reflector, wherein the reflector comprises a reflector body and a reflecting layer arranged at the inner face of the reflector body. The inner edge of the radial cross-section of the reflector body is a curve which comprises two axisymmetrical parabolic segments; the tail ends of the two parabolic segments are connected while the head ends are respectively connected with a zigzag line bending inwards; and the LED light source is arranged at the inward-bending edge of the reflector body. The LED lamp is characterized in that a point light source inside the lamp is transformed to a surface light source for emission, so people do not feel blinding even though they directly look at the lamp, thereby avoiding glare; and the lamp can approximately irradiate to a Lambertain type so as to satisfy the requirement of floodlight of the lamp.

Description

technical field [0001] The invention relates to an LED lighting fixture, in particular to an improved structure of a reflector of the LED lighting fixture. Background technique [0002] At present, with the advancement of science and technology, high-power SMD LEDs are not only used in flashlights, headlights, floodlights and other products, but also more and more used in indoor floodlights. However, due to the small size of the LED light source (generally, the diameter is less than 6mm) and the high luminous flux (above 60lm / W), the brightness on the surface of the LED is very high (generally, the maximum brightness exceeds 300,000cd / m 2 ). The surface brightness of general fluorescent tubes is about 7000-8000cd / m 2 , in the indoor environment, it can meet the glare requirements of the human eye, that is to say, the human eye can adapt to such brightness. When the human eye directly observes the lamps in operation, there will be no glare, and there will be no visual brigh...
