Problems solved by technology

[0002] Spotlights in the prior art are generally provided with a light source at the bottom of the luminous cup to emit light toward the mouth of the cup. Due to the limited space at the bottom of the luminous cup, it is generally difficult to increase the luminous efficiency of the entire lamp by increasing the number of light sources. In addition, due to The light source is set at the bottom of the reflector, it is difficult to form convection with the air, so it is difficult to improve the heat dissipation effect
In addition, since the position of the light source is fixed, the light emitting angle of the whole lamp cannot be changed by changing the position of the light source

Abstract

The invention discloses a reflector lamp adjustable in light emitting angle. Central light strength and overall luminous efficiency of the reflector lamp are greatly improved due to the fact that a first light emitting diode (LED) light source and a second LED light source are respectively arranged on the obverse side and the reverse side of a heat conduction base plate. Simultaneously, the heat conduction base plate, and the first LED light source and the second LED light source which are arranged on the obverse side and the reverse side of the heat conduction base plate are fully contacted with air, and additionally heat dissipation effects of the whole reflector lamp are greatly improved through a semiconductor chilling plate arranged between the heat conduction base plate and a heat conduction pillar. Furthermore, the heat conduction pillar which can be lifted is matched with a heat conduction sleeve through a thread, and therefore light emitting positions of the light sources can be conveniently adjusted, and then light emitting angles of the whole reflector lamp can be changed through a light reflection cup. The reflector lamp adjustable in light emitting angle is simple in structure, high in luminous efficiency, good in heat dissipation effect, and adjustable in light emitting angle.
