Described eyeglass top also is covered with a reflector, and the bottom of this reflector is installed on this substrate, and this eyeglass stretches in this reflector.

Described reflector comprises body and base plate, and this body has the reflection cavity that axially runs through, and this base plate is located at the bottom of this body, it has the groove that axially runs through, this groove communicates with this reflection cavity, and this substrate is installed on this base plate, and this eyeglass passes groove and stretches in the reflection cavity.

Described groove is a step trough, and this eyeglass bottom has outwardly directed shade portion, and this shade portion snaps in this step trough.

Be provided with the round anti-dazzling screen between described reflector and the eyeglass, the inner ring hoop of this anti-dazzling screen is at the outline of eyeglass, the inwall tight fit of the outer ring of this anti-dazzling screen and reflector.

Described led light source assembly also comprises copper ring, and this copper ring is fixed on the substrate, and this LED element is positioned at this copper ring, and is full of the printing opacity colloid in this copper ring, and this printing opacity colloid covers this LED element.

The beneficial effects of the utility model are that by the setting of eyeglass, the coloured light that the LED element is sent is even through this eyeglass back mixing light, thereby reaches the effect of white-light illuminating.

The specific embodiment

See also Fig. 1 to Fig. 9, the utility model led light source illuminating lamp comprises led light source assembly 1 and eyeglass 2, and this eyeglass 2 is installed on this led light source assembly 1.This led light source assembly 1 comprises ceramic substrate 11, LED circuit 12, LED element 13 and copper ring 14.This ceramic substrate 11 is square lamellar, and it has three installing holes 15 that run through setting.This LED circuit 12 is laid on this substrate 11.This LED element 13 has three, can send red, indigo plant and green glow respectively.This copper ring 14 in the form of a ring and be fixedly mounted on the substrate 11, three LED elements 13 all are positioned at the outside that 15 equal angles of 14, three installing holes of this copper ring are distributed in copper ring 14.Filled with printing opacity colloid 16 in this copper ring 14, this printing opacity colloid 16 covers these three LED elements 13, is used to protect these three LED elements 13 so that the circuit of this LED element 13 can not take off disconnected.

This eyeglass 2 is lens, and its material is the plastic cement PC material of optical grade.This eyeglass 2 roughly is the cap shape, and its middle position is recessed to be formed with host cavity 21, and these eyeglass 2 bottoms are provided with the shade portion 22 that level protrudes out.When this

eyeglass

2 and 1 assembling of this LED optical module, can this eyeglass 2 be fixed on the ceramic substrate 11 by the mode of gluing or buckle; After installing, this copper ring 14 and three LED elements 13 all are positioned at the host cavity 21 of eyeglass 2.

In order to increase the receipts optical efficiency, can outside eyeglass, be covered with reflector 3.This reflector 3 comprises body 31 and base plate 32.This body 31 is horn-like, and it has the reflection cavity 35 that axially runs through.This base plate 32 is square tabular, and its central position axis is to being penetrated with groove 33, and this groove 33 communicates for step trough 33 and with the reflection cavity 35 of body 31, is evenly distributed with three installing holes 34 around this groove 33.During installation, at first, led light source assembly 1 and eyeglass 2 are assembled into one; Then, eyeglass 2 is snapped in from the bottom to top in the step trough 33 of reflector 3, at this moment, part eyeglass 2 places the reflection cavity 35 of reflector body 31, and the shade portion 22 of eyeglass 2 and the cascaded surface butt of this step trough 33; At last, utilize screw to pass the installing hole 15,34 of ceramic substrate 11 and reflector 3 base plates 32 successively, thereby this eyeglass 2 and led light source assembly 1 are fixed on the bottom of reflector 3.Avoid unnecessary veiling glare to produce in order to strengthen illuminating effect, also can between eyeglass 2 and reflector 3, add thin anti-dazzling screen 4, this anti-dazzling screen 4 is round, its inner ring hoop is located on the outline of eyeglass 2, the inwall tight fit of its outer ring and reflector 3, thus can block unnecessary scattered light to reflect into the surround and cause the phenomenon of shadow or aperture.In addition, between ceramic substrate 11 and reflector 3 base plates 32, also be folded with Elastic plastic-rubber packing ring 5.

In the utility model, add that on existing various led light sources a slice is also fixed at the aspherical lens of required luminous purposes design, utilize light can follow Snell ' s Law law n1*sin θ 1=n2*sin θ 2 and produce refraction effect by the medium of different refractivity, reach the variation that changes diverse location curvature on the eyeglass, light is launched through changing its original trip footpath route behind the eyeglass from LED, and reach our required emission angle, uniformity, and mixed light effect, brightness changes excessive technical bottleneck with different angles so can to improve the existing luminosity of LED own, and can add reflector according to demand and increase the receipts optical efficiency, to see through the reflecting surface of designed high reflectance cover body than the light of wide-angle, use incidence angle and equal the angle of reflection principle, and the light reflection of originally dispersing is concentrated to effective district, increase whole receive optical efficiency and brightness, and and then reach energy-saving effect.

Above content be in conjunction with concrete preferred implementation to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field; under the prerequisite that does not break away from the utility model design; can also make some simple deduction or replace, all should be considered as belonging to the scope of patent protection that the utility model is determined by claims of being submitted to.
