Embodiment 1

[0018] The high-efficiency reflector for electrodeless lamps in this embodiment includes: a horizontal reflective side plate 1 and a bottom reflective plate 3 located below the horizontal reflective side plate 1, above the bottom reflective plate 3 and inside the lateral reflective side plate 1. The electrodeless lamp 4; the longitudinal section of the lateral reflective side plate 1 and the bottom reflective plate 3 forms a pair of involutes of the same base circle, and the central axis of the light-emitting tube of the electrodeless lamp 4 coincides with the orthocenter of the base circle.

[0019] In order to ensure that the light reflection efficiency is above 95%, the diameter of the luminescent tube of the electrodeless lamp 4 is smaller than the diameter of the base circle.

Embodiment 2

[0021] On the basis of Embodiment 1, the high-efficiency reflector for the electrodeless lamp of the present embodiment also has the following modifications:

[0022] The electrodeless lamp 4 has a pair of parallel light-emitting round tubes, the lateral reflective side plate 1 has a pair of symmetrically distributed on both sides of the pair of light-emitting round tubes, and the bottom reflector 3 is a double-sided cross-section forming two symmetrical involutes. Curved panel; the pair of light-emitting round tubes are respectively arranged in parallel directly above the two curved surfaces of the bottom reflector 3 and between the pair of lateral reflective side panels 1 .

Embodiment 3

[0024] On the basis of Embodiment 1 or 2, the high-efficiency reflector for the electrodeless lamp of the present embodiment also has the following modifications:

[0025] In order to further improve the reflection efficiency, the two ends of the pair of horizontal reflective side panels 1 are respectively connected with longitudinal reflective side panels 2, and the two longitudinal reflective side panels 2 are arranged symmetrically and parallelly; The lateral section of the side plate 2 is a section of involute of the spherical surface.

[0026] In order to prevent glare, a well-shaped grid is arranged between the horizontal reflective side panels 1 .

Abstract

The invention relates to a high-efficiency reflector for an electrodeless lamp, which has a simple structure and over 95 percent of reflective efficiency. The high-efficiency reflector for the electrodeless lamp comprises transverse reflective side plates and a bottom reflective plate arranged under the transverse reflective side plates, wherein the electrodeless lamp is arranged inside the transverse reflective side plates; the longitudinal sections of the transverse reflective side plates and the bottom reflective plate form a pair of involutes with the same base circle; and an central axis of a luminescent tube of the electrodeless lamp coincides with an orthocenter line of the base circle. In order to ensure over 95 percent of the reflective efficiency, the diameter of the luminescent tube is smaller than that of the base circle. In order to prevent glare, a groined grid is arranged between the transverse reflective side plates.

Description

technical field [0001] The invention relates to a reflector for a light source, in particular to a high-efficiency reflector for an electrodeless lamp. Background technique [0002] In the existing light source reflectors, part of the light is reflected back to the light source during use, resulting in low reflective efficiency of the reflector, and at the same time causing heat generation of the light source or accelerated aging of the phosphor powder, which affects the service life of the light source. Contents of the invention [0003] The technical problem to be solved by the invention is to provide a high-efficiency reflector for an electrodeless lamp with a simple structure and a reflection efficiency as high as 95%. [0004] In order to solve the above-mentioned technical problems, the high-efficiency reflector for electrodeless lamps of the present invention includes a horizontal reflective side plate and a bottom reflective plate located below the horizontal refle...
