Abstract

The invention provides an LED spotlight, which is suitable for far distance illumination. The LED spotlight comprises a reflector (1), a radiating support (2) which is arranged in an axial direction of the reflector (1) and at least two LEDs (3) which are arranged on the radiating support. A primary optical axis of the LED (3) faces the inner wall of the reflector (1). The LED spotlight has the advantages of good condensation effect, strong central light strength, high lamp optical flux utilization ratio, simple and compact structure and small size.

Description

technical field [0001] The invention relates to an LED lamp, in particular to an LED spotlight. Background technique [0002] LED is widely used as a high-efficiency light source in lighting fixtures, and major manufacturers in the lighting industry have also designed and produced many LED spotlight and floodlight fixtures. Such as figure 1 As shown, when LEDs are used as light sources for spotlights, in most cases one LED matches one reflector. The common LED spotlight structure is a simple combination of a parabolic reflector and an LED. The main optical axis OO of the LED faces the opening of the reflector. The light reflected by the reflector in the commonly used LED concentrating structure is only the light that intersects with the main optical axis OO of the LED at 30 degrees or 45 degrees. The luminous flux of this part is only about 1 / 3 of the total luminous flux of the LED. The stronger light in the center It cannot be utilized, resulting in low central light int...
