PAR (Parabolic Aluminum Reflector) light

Abstract

The invention provides a PAR (Parabolic Aluminum Reflector) light. The PAR light comprises a light holder, a plastic housing, and a light transmitting cover which are connected in sequence; a constant-current driving power supply, an aluminum profile radiator and an LED light source plate are arranged in the plastic housing; the constant-current driving power supply is electrically connected with the LED light source plate and the light holder; the LED light source plate comprises a base plate and at least one group of annularly-distributed small-power LED light beads, wherein the at least one group of annularly-distributed small-power LED light beads is arranged on the base plate; the base plate is connected and fixed to a step arranged in the plastic housing and tightly clung to the aluminum profile radiator. According to the PAR light, a plurality of LED light beads are arranged to form an annular structure, and uniform and reasonable distribution of the light within the radiating scope of the light beads is realized through the annular distribution of the LED light beads, namely, the luminance is gradually reduced from the center to the periphery, and seamless transition of light is realized, and thus light spots can be avoided during radiating, and as a result, the purpose of effectively utilizing light is reached; in addition, the PAR light is safe and reliable to use, high in light utilization rate and good of radiating effect.

Description

technical field [0001] The present invention relates to the technical field of lighting, in particular to a PAR lamp. Background technique [0002] PAR lamp is an emerging LED lamp whose main structure is to encapsulate the LED light source in a reflector, so that the PAR lamp has the advantages of small size, long service life and high efficiency and energy saving of LED lamps. However, the LED lamp beads in the existing PAR lamp are usually arranged in a row, which causes the problem of uneven light distribution in the irradiation range, so that the PAR lamp will have light spots when it is irradiated, so that the light source cannot be more effective. usage of. At the same time, the existing PAR lamp usually uses a plastic light-transmitting cover, which not only affects the light transmittance and reduces the utilization rate of light, but also tends to change color under long-term use, thereby affecting its lighting effect. SUMMARY OF THE INVENTION [0003] The purp...

Problems solved by technology

However, the LED lamp beads in the existing PAR lamps are usually arranged in rows, which causes the problem of uneven light distribution in the irradiation range, so that the PAR lamps will have light spots when they are irradiated, resulting in the inability of the light source to be more effective. usage of

At the same time, the existing PAR lights usually use a plastic light-transmitting cover, which not only affects the light transmittance, reduces the light utilization rate, but also tends to change color under long-term use, thus affecting its lighting effect.
