Problems solved by technology

Such a placement method is convenient for the light emitted by the LED to be projected directly, which is conducive to the improvement of the light output efficiency of the lamp. However, in the process of making a lamp with a small angle, the light processed by this light distribution method will appear to be directly projected from the light source. , the light is not processed by the reflector, it is easy to cause glare, and there is a more obvious overflow light halo around the projected spot

Embodiment Construction

[0019] The following descriptions are only preferred embodiments of the present invention, and do not limit the scope of the present invention.

[0020] Examples, see attached figure 1 , 2 , 3. An optical system of an LED lamp placed on the side of the light source, including a reflector 1, an aluminum substrate 2 and LED lamp beads 3. The number of aluminum substrates can be 1, 2, 3, 4, 5, 6, etc., according to actual needs It is determined that the aluminum substrate 2 is provided with an installation plane 5 perpendicular to the horizontal plane, the LED lamp bead 3 is a hemisphere, which is arranged on the installation plane 5, and there are multiple LED lamp beads in a rectangular array or a ring array Arranged on the aluminum substrate 2 in a manner, generally in a rectangular array; the axis of the LED lamp bead 3 is perpendicular to the installation plane 5, with such an arrangement, the light emitted by the LED lamp bead directly hits the reflector On the surface of...

Abstract

The invention discloses an LED lamp optical system with a light source laterally arranged. The LED lamp optical system comprises a reflection cup, an aluminum substrate and an LED lamp bead. The aluminum substrate is provided with an installation plane which is perpendicular to a horizontal plane. The LED lamp bead is arranged on the installation plane, and the axis of the LED lamp bead is perpendicular to the installation plane. According to the LED lamp optical system, light emitted by an LED lamp is cast on the reflection cup for light distribution processing, secondary processing efficiency of the light by the reflection cup is increased, the occurrence of spill light is reduced to a great extent, the proportion of direct light of the LED lamp is increased, and the vignetting effect caused by glare and light spots is reduced. In this way, excellent usage effects on large-angle secondary light distribution are achieved, processing of collimation light of small-angle cast light illumination is facilitated as well, and the collimation efficiency of light emitted by the LED lamp can be improved to a great extent.

Description

technical field [0001] The invention relates to the technical field of lighting fixtures, and more specifically relates to an optical system of an LED lighting fixture placed on a light source side. Background technique [0002] At present, LED, as a new type of green and environment-friendly light source, is widely used in many lighting fields such as indoor and outdoor functional lighting, decorative lighting and landscape lighting. Since the light distribution emitted by LED is similar to a Lambertian body, it must be corrected for most lighting occasions. The light source performs secondary light distribution, and performs secondary optical processing on this near-Lambertian light distribution, so that the processed light distribution can meet the requirements of specified lighting occasions. In the process of secondary light distribution for near-Lambertian light sources emitted by LEDs, secondary lenses and reflector cups can be used. A reflector and a lamp using the ...
