Embodiment Construction

[0024] refer to figure 1 and figure 2 The shown flip-chip total reflection secondary optical LED lamp includes a reflective cup 1 and an LED light source 2. The LED light source 2 is set in the reflective cup 1 and is located in the range of the reflective area. The irradiation direction of the LED light source 2 is The reflection direction of the reflective surface of the reflective cup 1 is opposite to form an LED light source 2 flip-chip total reflection double reflection optical LED lamp.

[0025] The LED light source 2 is a single LED module light source, the LED light source 2 is set at the opening of the reflector 1, and a fixing bracket 11 is arranged at the opening, and the LED lamp is mounted on the fixing bracket 11. The fixing bracket 11 is composed of an annular fixing part 111 and a fixing beam 112. The annular fixing part 111 is a ring-shaped mounting connector fixed on the opening edge of the reflector cup 1; the fixing beam 112 is arranged on the annular fix...

Abstract

The invention belong to the field of lamps, discloses a method of improving a secondary optical radiation glare of an LED (Light-emitting Diode) light source and an LED lamp adopting the method, and particularly relates to a secondary optical radiation LED lamp. The method of improving the secondary optical radiation glare of the LED light source is characterized in that the LED light source reversely radiates a reflection cup to allow that the radiation direction of the LED light source is opposite to the reflection direction of the reflection cup, and the whole light rays of the LED light source are reflected out by the reflection cup. According to the method and the LED lamp, the reflection cup controls the LED light source to radiate the light rays wholly, and changes the radiation directions of light rays of the LED light source, and all light radiated by the LED light source are redistributed and recombined, thereby reducing the glare generated by the LED light source greatly, and improving the using effect of the LED light source effectively.

Description

technical field [0001] The invention belongs to the field of lamps, and in particular relates to an LED lamp for secondary optical irradiation. Background technique [0002] At present, the LED light source is illuminated in a directional manner of about 110°, and direct illumination will produce strong glare, causing serious glare problems. Therefore, the application of LED light sources on lamps requires secondary optical design to change the distribution of light to achieve the purpose of reducing the glare of LED light sources. [0003] Today's secondary optics can change the glare problem of LED light source irradiation through the following three methods. [0004] 1. Secondary optics of lamp cups. The light emitted by the LED light source is in the same direction as the light outlet of the lamp. The main features are: reflect the light emitted by the LED light source, change part of the light emitted by the LED light source, and redistribute it. Combination, to achie...
