Abstract

The invention provides a novel PAR (parabolic aluminized reflector) lamp, which comprises reflectors, a power supply and a lead, wherein the reflectors are respectively arranged on upper surfaces of two side ends of an LED (light-emitting diode) aluminum-based lamp panel; the power supply and the LED aluminum-based lamp panel are connected through the lead; the LED aluminum-based lamp panel is provided with an LED packaged chip; the LED packaged chip is welded to the LED aluminum-based lamp panel in an annular surface mounting manner to form an annular LED module. According to the novel PAR lamp provided by the invention, by means of indirect reflected illumination, light emitted from the annular LED module irradiates to the reflectors firstly but does not directly radiate, and a reflected beam angle is controlled through the radian curve design of each reflector. The treatment mode has the advantages that an LED luminescent source cannot directly irradiate into human eyes by flexibly utilizing the characteristics of luminescence of an LED, and therefore the glare problem can be completely solved.
