Light-condensing reflector and bean-container lamp comprising same

Abstract

The invention relates to a light-condensing reflector and a bean-container lamp comprising the same. The light-condensing reflector specifically comprises a reflection bowl and a reflecting light-splitting column used for reflecting an incident light ray to a bowl-shaped reflection surface, wherein the reflection bowl comprises a bottom centre part, a reflection bowl edge for limiting a bowl rim plane, and the bowl-shaped reflection surface extending between the bottom center part and the reflection bowl edge; and the reflecting light-splitting column extends towards the central area of the bowl rim plane from the bottom center part of the reflection bowl. The bowl-shaped reflection surface preferably is a quadric surface. The outer surface of the reflecting light-splitting column preferably is a paraboloid, and the vertex of the paraboloid is located below the light-emitting surface of a light source. A light source assembly preferably is a COB LED surface light source. The emitting angle of the light ray emitted by the light source after being subjected to the light-splitting of the reflecting light-splitting column and the reflection of the bowl-shaped reflection surface is less than or equal to 7 degrees. The light ray of the bean-container lamp disclosed by the invention is soft and free from glare, and good in concentration effect, and light distribution with a small angle of less than or equal to 7 degrees is realized.

Description

Background technique [0001] Bean gall lamp (or bold lamp, AR111) is a type of high-power lighting fixture commonly used in commercial lighting. Quadric reflectors, lenses, and combinations of reflectors and lenses are usually used as secondary light distribution devices to achieve the desired design goals. The light distribution angles generally have specifications such as 6°, 24°, and 40°. [0002] With the development of LED light source technology, LED light source has become the first choice for high-power light source types due to its high efficiency, energy saving, controllable and stable luminous characteristics. [0003] People hope to design a bean gall lamp with an LED light source based on the lamp type of the bean gall lamp and its existing size standard. [0004] However, for high-power LED spotlights with quadric reflective cups, since the light emitted by the LED light source is directional, when people set the LED light source on the bottom of the quadric refl...

Problems solved by technology

However, in this solution, secondary light and overflow light are unavoidable, and at the same time, the weight of the bean bulb is greatly increased, and the power of the LED light source of the lamp bead type is limited.

[0006] Some manufacturers use light source suspension to achieve small-angle light distribution effects. The existing suspension solution (that is, suspend the LED light source at the mouth of the reflector cup, and the light-emitting surface faces the bottom of the reflector cup) has the same light distribution angle as the diameter of the light-emitting surface of the light source. Therefore, it is impossible to achieve a smaller angle of light distribution comparable to that of a bean gall lamp using a traditional light source under practical power. Light

At the same time, the power of the LED light source in this solution is limited and can only be within 15W. Higher power will bring a heat load that the system cannot bear
