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.
