Spot lamp with water mirror for focusing and color modulation

Abstract

The invention relates to a spot lamp with a water mirror for focusing and color modulation. By means of the spot lamp with the water mirror for focusing and color modulation, the problem that the color modulation cost of an existing spot lamp is high, or the front end structure of the existing spot lamp is excessive and consequently using is not convenient is solved. The spot lamp comprises a lampcap and a lampshade arranged on the front side of the lamp cap, the front end of the lamp cap is provided with a light source, and the rear side of the lamp cap is provided with a plurality of cooling fins arranged in parallel. The spot lamp is characterized in that the water mirror is arranged at the front end of the lampshade, the water mirror is a convex lens, the lamp cap, the lampshade and the water mirror are arranged coaxially, the outer wall of the water mirror is provided with a glass shell which is filled with colored cooling liquid, a liquid outlet of the water mirror is connectedwith a heat exchange coil pipe through a connecting pipe, the heat exchange coil pipe is attached to the cooling fins, a liquid supply opening of the water mirror is connected with a cooling tank through a liquid delivery valve, the cooling tank contains the cooling liquid, and the tail end of the heat exchange coil pipe is connected back to the cooling tank through a liquid return valve. The water mirror achieves focusing and color modulation for the spot lamp, and as the cooling liquid of the water mirror carries away heat of the lamp cap, the cooling effect of the spot lamp is improved.

Description

technical field [0001] The invention belongs to the field of lamps, and relates to a spotlight capable of color adjustment, in particular to a spotlight which adopts a water mirror to focus and adjust light. Background technique [0002] Spotlights are a common lighting fixture with a concentrated lighting range. Spotlights generally include a lamp cap and a lampshade. A circuit structure is set inside the lamp cap. A luminous body is arranged at the front end of the lamp cap. A lampshade is arranged around the luminous body on the front side of the lamp cap. The light is reflected forward. Common illuminant light sources are scattered light sources, and the light concentrating is not good. Therefore, a convex lens can be installed on the front side of the lampshade of the spotlight to condense the light emitted by the light source to form a beam. The convex lens is generally made of glass. In addition, the light source of the spotlight can be a single white light source, ...
