Abstract

The utility model discloses a condenser lens for a 3-bead combined light-emitting diode (LED) floodlight, and relates to a lens for an LED lamp. The condenser lens comprises a lens body. The lens body comprises three condensers of which each has a circular truncated cone shape. The large bottom end of each condenser is the emergent surface of the condenser. The emergent surfaces of the three condensers are positioned in the same plane, and form the emergent surface of the condenser lens for the 3-bead combined light-emitting diode (LED) floodlight. A hole is reserved on the central part of the emergent surface of each condenser. An assembly hole for an LED is formed at the small bottom end of each condenser, and the LED is arranged in the assembly hole. The hole wall of each assembly hole, which is opposite to the emergent surface of a corresponding condenser, is the incident surface of the condenser. The outer edges of the large bottom ends of any two of the three condensers are tangent. Light spots are projected to form a round, a light projection and diffusion angle is 25 degrees, light is uniformly projected in a centralized way, and light colors can be transformed by replacing LED lamp wicks emitting different colors; and the lens is low in energy consumption, small in size and long in service life.

Description

A kind of collector lens of 3 pearl combined LED Projecting Lamps

Technical field

The utility model relates to the lens that are used for the LED lamp, refers to a kind of collector lens of 3 pearl combined LED Projecting Lamps especially.So-called 3 pearl combined types promptly refer to the luminescence unit (following agreement) that 3 light emitting diode combined form.

Background technology

Outside the building views such as profile, square, park, sub-district and various tourist attractions throw light on usually at present.Beautify the environment to reach, in the Landscape Lighting of rendered atmosphere and effect; What generally use is conventional lamp, and like incandescent lamp, fluorescent lamp, high-pressure sodium lamp, metal halide lamp, high-pressure mercury lamp and low-pressure sodium lamp etc., the major defect of this type light fixture is to use the life-span short; Light efficiency is low; Energy consumption is high, and photochromic control is difficult, and volume is big and maintenance cost is high.Also there is a certain distance in this with the requirement that country advocates energy-saving and emission-reduction.

Summary of the invention

The utility model is intended to overcome the above-mentioned deficiency of prior art, and meeting the market requirement provides a kind of collector lens of 3 pearl combined LED Projecting Lamps.Its characteristics: the rounded projection of projection shape of

hot spot, light is concentrated projection;

illumination projection evenly, photochromic can conversion;

light source adopts the LED luminous tube, and energy consumption is low, volume is little, long service life and maintenance cost are low.

For this reason, the collector lens of a kind of 3 pearl combined LED Projecting Lamps of the utility model adopts following technical scheme:

The collector lens of a kind of 3 pearl combined LED Projecting Lamps of structure the utility model; Comprise lens body; Said lens body comprises 3 condensing bodies; Said condensing body is circular cone shape, and the big bottom of its condensing body is the exit facet of condensing body, and the exit facet of 3 said condensing bodies is positioned at same plane and constitutes a kind of exit facet of collector lens of 3 pearl combined LED Projecting Lamps; System one hole is opened in the centre of the exit facet of said condensing body, and this hole is called the outgoing face of condensing body; The little bottom of its condensing body is shaped on the pilot hole that light emitting diode is installed, and light emitting diode is installed on said pilot hole, and the hole wall that the exit facet of pilot hole and said condensing body is relative is the plane of incidence of said condensing body; In 3 condensing bodies, the outer rim of the big bottom of wherein any 2 condensing bodies is tangent.

Technique scheme is further set forth:

The interior circle of the outer rim of the big bottom of 3 condensing bodies and an external annulus is tangent, and this external annulus protrudes out and forms a circular step.

Be shaped on the assembling post that strengthens the lens body mechanical strength on the lens body, said assembling post is column, and short transverse of its assembling post is consistent with the short transverse of said condensing body, assembles the position, space between the condensing body that post is positioned at inner of lens body.

The concrete shape of the plane of incidence designs according to the crevice projection angle that optical characteristics and this projection source of light emitting diode requires to reach.

Lens body is made with transparent material, like plastic cement PMMA etc.

The beneficial effect of the utility model is: one of which, and the rounded projection of projection shape of hot spot, ray cast is scattered and is angle 25 degree, and light is concentrated projection; Its two, illumination projection evenly photochromicly can realize conversion through the LED wick (being light emitting diode) of more changing different colours; Its three, light source adopts light emitting diode, energy consumption is low, volume is little, long service life and maintenance cost are low.
