Light path heat dissipating combination system for spotlight

Abstract

The invention discloses a light path heat dissipating combination system for a spotlight. The light path heat dissipating combination system comprises a light path system and a heat dissipating system, wherein the light path system comprises a COB integrated light source, a light source light receiver, an aspherical mirror and a plano-convex lens; the light source light receiver is a cylinder body of which two ends are opened; a light emergent outlet is formed in one end of the cylinder body; a conical surface concaved into the cylinder body is arranged at the light emergent outlet end; an opening is formed in the bottom of the conical surface and is used as a light incident inlet; the end face of the light incident inlet and the end face of the other end of the cylinder body are positioned on the same horizontal plane; a vacuum coating layer is arranged on the conical surface; the vacuum coating layer and the conical surface jointly form a reflection part of the light source light receiver; the light incident inlet is greater than the light emergent outlet; the aspherical mirror is fixed at the light emergent outlet of the light source light receiver by an aspherical mirror pressing plate; an aspherical mirror silicone buffer washer is arranged between the aspherical mirror pressing plate and the light source light receiver; and center lines of the plano-convex lens, the aspherical mirror, the light source light receiver and the COB integrated light source are positioned on the same axis. The light path heat dissipating combination system disclosed by the invention has the characteristics of low cost, higher luminous efficacy, excellent heat dissipation potential and capability of prolonging the service life of the spotlight.

Description

technical field [0001] The invention relates to a spotlight, in particular to a heat dissipation combination system for spotlights and roads. Background technique [0002] Spotlight (spotlight) refers to a lamp that can use a condensing lens or a reflector to condense light. Spotlights cast a highly directional beam that produces bright highlights and sharp, dark shadows. [0003] At present, there are many kinds of spotlights on the market. The characteristics of spotlights are that the light projection distance is long, the range is obvious, the light direction is strong, its spot quality is high, the uniformity is good, and the edge of the illuminated object can be clear and sharp. , is a better local light transmission effect lamps. At present, threaded lens spotlights are the most, and threaded lens spotlights are Fresnel spotlights. Its optical system is composed of Fresnel lenses and spherical reflectors. Move back and forth along the optical axis to change the pro...

Problems solved by technology

However, since the light source is packaged by multiple chips, or arranged on the same PCB board by multiple independent LEDs, there are square or circular arrangements, when the light source is located at the focal plane of the Fresnel lens, the Neel lens will project the images of neatly arranged LED chips, and the light spots will appear as multiple small squares instead of circular uniform light spots, so it will affect the illumination effect of LED spotlights

Although the shape of the spot can be improved by defocusing, the beam angle will become larger after defocusing, and due to the existence of chromatic aberration, sometimes a yellow circle will appear on the edge of the spot, which will greatly affect the illumination effect of the spotlight
