Abstract

The utility model belongs to an illumination device and particularly relates to an LED (light emitting diode) lens assembly installed on a high-power LED lamp. The LED lens assembly comprises a lens base (2) and a lens (3), wherein the lens (3) is arranged in a lens hole (10) of the lens base (2); and the position of each lens (3) is corresponding to the position of each LED light source (7) welded on a circuit board (11). The LED lens assembly is characterized in that: a lens cover (1) is arranged in the front of the lens base (2); a light outlet (9) in the lens cover (1) is corresponding to the lens (3); the thickness of the lens cover (1) is not less than 10mm; the light outlet (9) in the lens cover (1) can shield stray light around the lens (3); a main light beam of an LED is irradiated to the irradiated surface along the light outlet (9) of the lens cover (1); and light spots are clearer through centralized irradiation of a plurality of LEDs. The LED lens assembly is suitable for the high-power LED lamp used on film and television stages, can effectively control the light attenuation of light irradiated by the LED after the scattering of the lens, has a simple structure and requires low manufacturing cost.

Description

A kind of LED lens subassembly

Technical field

The utility model belongs to ligthing paraphernalia, relates to a kind of LED lens subassembly that is installed on the high-power LED lamp.

Background technology

Advantages such as low power consuming, operating temperature are low, nontoxic, radiationless because LED has, long service life have become new generation of green environmental protection lighting light source, are widely used in various lighting fields.Along with the appearance of high-power LED light source, high-powered LED lamp is used widely in many occasions such as video display stage lighting, Tunnel Lamp, street lamps.But the LED light beam is easily dispersed, meeting loss towards periphery, and existing LED lens can not reach and make hot spot concentrate and the requirement that strengthens brightness of illumination.Thereby need a kind of large-power lamp needs that are applicable to of exploitation, light beam the is concentrated influence of gathering, can effectively control veiling glare, the effective rate of utilization of raising LED light, and low cost of manufacture, lens subassembly easy for installation.

Summary of the invention

The technical problem that solves:

A kind of LED lens subassembly is provided, is installed in the high-power LED lamp front end, the scattered beam of LED is directed on the plane of illumination, light fixture irradiation hot spot is concentrated, brightness of illumination improves, and simple in structure, low cost of manufacture.

The technical scheme that adopts:

A kind of LED lens subassembly, comprise the lens pedestal and be installed on lens in the lens opening position in the lens pedestal, the position of each lens is corresponding with the position of each LEDs on being welded on circuit board, it is characterized in that: lens cap arranged in that the lens pedestal is pre-installed, the light hole position in the lens cap be installed on the lens pedestal in the lens opening position in lens corresponding.

Beneficial effect:

The light that sends as LED reflects through lens, the light that LED penetrates has the part scattering, light hole in the lens cap is directed to plane of illumination with scattered light, the scioptics cover is gathered concentrates light beam, can effectively control the influence of veiling glare, improve the effective rate of utilization of LED light, thereby improve Luminaire efficiency, and simple in structure, low cost of manufacture.

The specific embodiment

Further explanation in detail in conjunction with the accompanying drawings:

Shown in Fig. 1,2,3,4, a kind of LED lens subassembly, it comprises lens cap 1, and the light-emitting window 9 that is honeycomb arrangement is arranged in the lens cap 1; Lens cap 1 is contained on the lens pedestal 2, and lens opening position 10 and recessed locating hole 6 are arranged in the lens pedestal 2, and the lens opening position 10 in the lens pedestal 2 is corresponding with the light-emitting window 9 in the lens cap 1; Locating hole 6 recessed in the lens pedestal 2 is corresponding with the protruding reference column 4 on the lens cap 1; Lens 3 are installed on the groove in the lens opening position 10; Described lens 3 bodies are bowl-shape, and last end section is a circular arc, and the bottom is provided with the lens accommodation space 8 that can insert led light source 7, and led light source 7 is positioned at lens accommodation space 8, and led light source 7 is welded on the circuit board 11; Lens opening position 10 in the lens pedestal 2 is corresponding with led light source 7.

Described lens cap 1 thickness is not less than 10mm, is provided with the reference column 4 of projection on lens cap 1 and face that lens pedestal 2 contacts, and the reference column 4 of projection is mutual corresponding with the recessed locating hole of lens pedestal 26, and is fixed together with clench nail 5 mutual fastening-types.

All be provided with the light-emitting window 9 of lens cap 1 before each lens 3 of the present invention, its objective is: when light that led light source 7 sends after lens 3 refractions, the light-emitting window 9 of lens cap 1 can block the veiling glare around the lens 3, the main beam of LED shines plane of illumination along the light-emitting window 9 of lens cap 1, and plurality of LEDs cover hot spot is more clear.

The utility model is applicable to video display stage high-power LED lamp, the said lens assembly is installed in the light fixture front end, effectively control LED penetrates the light impairment of rays pass through lens scattering, scattered beam is guided on the plane of illumination, light fixture irradiation hot spot is concentrated, brightness of illumination improves, and simple in structure, low cost of manufacture.
