Description

High power cold light zoom reflective spotlight

technical field

The utility model belongs to a lighting fixture, in particular to a professional lighting fixture for large and medium venues, in particular to a high-power cold-light variable-focus reflective spotlight.

Background technique

At present, there are various types of lighting lamps used in large and medium-sized stadiums, theaters, squares and other places, many of which use incandescent bulbs and quartz-halogen tungsten bulbs as light sources, the structure of spherical reflectors, light sources and lenses, etc. Co-located on the same central axis to form a transmissive optical system, its disadvantages are low light efficiency, high energy consumption, uneven light spots, and poor light quality. Now some European and American countries adopt deep ellipsoid mirror reflection optical system, and the mirror is made of glass; some products adopt aluminum spherical total reflection optical system, these products have their own advantages and practicability, but there are also some shortcomings , For example, the glass material is not safe and fragile, and some calibers are too small, which is not conducive to heat dissipation. Therefore, it is necessary to propose a high-power lighting fixture with a more reasonable structure, energy saving, higher light utilization rate, better light quality, novel and practical structure, so as to meet the lighting needs of large and medium-sized venues.

Utility model content

The purpose of this utility model is to address the above problems, and propose a high-power cold light zoom reflective spotlight, which is equipped with a parabolic reflector, an adjustable bulb, and a shading ring, which has a high light utilization rate and saves energy. , good light quality, anti-glare, easy adjustment, strong and durable advantages.

The purpose of this utility model is achieved through the following technical solutions: a high-power cold light zoom reflective spotlight mainly includes a light box, a light bulb, and a reflector, and is characterized in that: the light bulb is a metal halide light bulb or a quartz tungsten halogen light bulb One of them; the reflector is a parabolic arc made of stainless steel plate, the mirror surface is coated with organic glaze and luminescent dielectric film, and the back of the reflector is provided with a cooling tray made of aluminum castings, and the lamp of the light bulb The seat is set in the central hole of the reflector, and the electric light bulb can move back and forth through its lamp seat to adjust the focal length and change the width of the beam angle; 3-8 circles are arranged directly in front of the central axis of the reflector. The shading ring formed by the barrel is fixed in front of the central axis of the reflector through a ten bracket at the outer mouth of the reflector.

A light control tube is provided in front of the shading ring, a front mouth ring is provided at the front mouth of the light control tube, a rear mouth ring is provided at the rear mouth, and a A circular hole the same size as the reflector port.

The concave surface of the reflector can be designed as a single curved surface or a conical truncated plane to meet the needs of different places.

Because the utility model adopts the reflective mirror with parabolic arc surface, and the organic glaze and luminescent medium film are coated on the surface of the mirror surface, the light utilization rate is effectively improved, and the effect of high light efficiency and luminescent light is realized. Above, the emitted light is parallel light, forming a high-brightness concentrating state; the set shading ring can block the direct light of the bulb and effectively control the scattered light reflected by the reflector, so that the beam illuminates in the specified direction, effectively preventing Glare is also known as the stimulation of disturbing light or spilled light to human eyes; the adjustable device of the bulb makes the luminous effect better adjusted. Therefore, compared with the prior art, the utility model has the advantages of reasonable structure, convenient adjustment, high light utilization rate, energy saving, good luminous effect and anti-glare.
