Double reflector zoom light

Abstract

The invention relates to the technical field of lighting equipment, in particular to a double-reflecting-cover zooming lamp which comprises a fixing ring, a light source, a lens and a zooming mechanism. The light source is fixed on the fixing ring. The zooming mechanism is arranged on the fixing ring. The lens and the zooming mechanism are relatively fixed and are placed in the lighting direction of the light source. A first reflecting cover and a second reflecting cover are further included. The first reflecting cover is fixed at the fixing ring, and the light source is arranged in the first reflecting cover in a covering mode. The second reflecting cover is fixed on the zooming mechanism, and the lens is arranged in the second reflecting cover in a covering mode. According to the double-reflecting-cover zooming lamp, double-reflecting-cover design is used, the using rate of light rays is effectively improved, energy loss is lowered, a wall groove guiding type zooming structure is used, zooming accuracy is high, the structure is compact, lens swinging is lowered, sliding is smooth, light spot excursion is avoided, the structure is simple, convenience and practicability are achieved, high market prospect is achieved, and the double-reflecting-cover zooming lamp is suitable for vigorous promotion.

Description

Technical field [0001] The invention relates to the technical field of lighting equipment, in particular to a double-reflector zoom lamp. Background technique [0002] Under the background that the current global energy shortage is rising again, energy saving is an important issue we face in the future. In the field of lighting, the application of LED light-emitting products is attracting the attention of the world. LED is a new type of green light source product. It must be the trend of future development. The 21st century will enter the era of new lighting sources represented by LEDs. LED is called a green light source, has the characteristics of energy saving, environmental protection, long life, small size, etc., and can be widely used in various fields such as indication, display, decoration, backlight, general lighting and urban night scenes. [0003] Zoom LED lamps are optical zoom devices, which require high accuracy. If the accuracy of the device is low, the convex lens w...

AI Technical Summary

Problems solved by technology

[0003] Zoom LED lamps belong to optical zoom equipment, which requires high precision of the equipment. If the precision of the equipment is low, the convex lens shakes during the zooming process, which will make the spot shift and fail to meet the requirements.

Moreover, if the zoom light with lens is used, most of the light will be focused through the lens, but some light will still be refracted to form astigmatism, which reduces the utilization rate of light.
