Abstract
The utility model relates to an LED lamp reflecting shade which is a rotary shell with a cambered surface, formed by the rotation of an arc around a central line, the upper end of the shell is provided with an LED lamp bead mounting hole, the lower end thereof is provided with a light outlet, and the inner surface of the rotary shell with the cambered surface is provided with a light-reflecting layer. The LED lamp reflecting shade can be used on LED lamp bead combined luminaire in occasions requiring for large-area and uniform illumination, such as workshops, halls, stores and the like. The LED lamp reflecting shade is designed with the maximum effective projection light illumination efficiency according to the divergence angle of the LED lamp bead, the illumination curve and the space luminescence distribution characteristics. The LED lamp bead combined luminaire can illuminate the illuminated surface uniformly by virtue of the collection of light emitted by single LED lamp beads using the reflecting shade independently, thus obtaining high brightness and illumination with high uniformity. The reflecting shade gathers all diverging light of the single LED lamp beads, distributed with solid 120-degree space luminescence, in the range of about 48-degree solid angle in the front most effectively, thus high-efficiently utilizing all light energy of the LED lamp beads.
Description
Technical field
The utility model belongs to the lighting parts, particularly a kind of LED reflector of lamp.
Background technology
Present owing to the high-brightness LED lamp pearl occurs, because high-brightness LED lamp pearl volume is little, the brightness height, consumed power is few, therefore is widely used in the exploitation of illuminating lamp.Because the volume of high-brightness LED lamp pearl is little, its light angle of divergence, illumination curve, the space luminescence distribution characteristic is different from common illuminating lamp, again because the occasion difference that is used to throw light on, the purposes difference of illumination, so the LED reflector of lamp is different from existing all illuminating lamp reflection shields.Therefore the illumination of high-brightness LED lamp pearl is adopted in specific occasion and special-purpose, and, therefore will design the LED light special reflection shield in order to utilize the high-brightness LED lamp pearl characteristics of luminescence efficiently
Summary of the invention
Technical problem to be solved in the utility model is: a kind of LED reflector of lamp is provided.It is the lampshade of LED lamp that is applied to the occasion of the large tracts of land in factory building, hall, shop, supermarket and uniform illumination.
The technical solution of the utility model is:
A kind of LED reflector of lamp is characterized in that: it is one and rotates form one rotation cambered surface housing by camber line around center line, and there is LED lamp pearl installing hole the upper end of housing, and the lower end of housing is a light-emitting window, and the inner face of rotation cambered surface housing has reflector layer.
The shape of its camber line is: at the reclinate top, 2.6mm place of vertical center line one side arc, the radius of this top arc is approximately 6.0mm, and the distance of the following end distance center line of top arc is 5.0mm, the top arc vertical height be 2.5mm; The downward smooth connection radius of the lower extreme point of top arc is approximately the upper extreme point of the middle part arc of 42.5mm, and the whole of middle part arc highly is 15.0mm vertically, and middle part arc upper extreme point is 5.0mm apart from the distance of center line, and middle part arc lower extreme point is 9.9mm apart from the distance of center line; Middle part arc lower extreme point connects bottom arc upper extreme point, and the radius of bottom arc is approximately 40.0mm, and the vertical height of bottom arc is 2.5mm, and bottom arc lower extreme point is 10.0mm apart from the distance of center line; The lower extreme point of bottom arc connects a short-term of near linear, the vertical height 2.5mm of short-term, and the short-term lower extreme point is 10.0mm apart from the distance of center line.
The utility model effect is:
This LED reflector of lamp is to use the lampshade of the single led lamp pearl on the high-brightness LED lamp pearl combination lamp of the occasion that the large tracts of land and the uniform illumination in factory building, hall, shop, supermarket etc. require.It is the light angle of divergence according to LED lamp pearl, the illumination curve, and the space luminescence distribution characteristic, (see figure 3) is to pursue the reflection shield of maximum effectively projection light illumination efficiency design.Single led lamp pearl on LED lamp pearl combination lamp is used this reflection shield, the set of the light that sends by each single LED lamp pearl that has this lampshade, the face to be illuminated of (preceding) side under the LED lamp pearl combination lamp can be thrown light on equably, obtain high brightness, the illumination of high evenness.Whole diverging light maximums that the solid 120 of each LED lamp pearl is spent space luminescence distribution concentrate in the scope of the about 48 degree solid angles in the place ahead effectively effectively, efficiently utilize whole light energies of LED lamp pearl.

The specific embodiment
A kind of LED reflector of lamp as shown in Figure 1, it is one and rotates form one rotation cambered surface housing 1 by camber line around center line, and there is LED lamp pearl installing hole 2 upper end of housing, and the lower end of housing is a light-emitting window 3, and the inner face of rotation cambered surface housing has reflector layer 4.
The shape of the camber line of composition rotation cambered surface housing as shown in Figure 2 is: at the reclinate top, 2.6mm place of vertical center line one side arc, the radius of this top arc is approximately 6.0mm, the distance of the following end distance center line of top arc is 5.0mm, the top arc vertical height be 2.5mm; The downward smooth connection radius of the lower extreme point of top arc is approximately the upper extreme point of the middle part arc of 42.5mm, and the whole of middle part arc highly is 15.0mm vertically, and middle part arc upper extreme point is 5.0mm apart from the distance of center line, and middle part arc lower extreme point is 9.9mm apart from the distance of center line; Middle part arc lower extreme point connects bottom arc upper extreme point, and the radius of bottom arc is approximately 40.0mm, and the vertical height of bottom arc is 2.5mm, and bottom arc lower extreme point is 10.0mm apart from the distance of center line; The lower extreme point of bottom arc connects a short-term of near linear, the vertical height 2.5mm of short-term, and the short-term lower extreme point is 10.0mm apart from the distance of center line.
This LED reflector of lamp is the lampshade design used of the single led lamp pearl on the high-brightness LED lamp pearl combination lamp of special occasion for the large tracts of land that is used in factory building, hall, shop, supermarket and uniform illumination.Be the light angle of divergence according to its LED lamp pearl of adopting, the illumination curve, space luminescence distribution characteristic (see figure 3) is to reach the effective optical illumination efficient purpose of maximum projection.It is to use the lampshade of each single LED lamp pearl on by LED lamp pearl matrix group combined lamps.The diverging light maximum of the solid 120 degree space luminescence distribution of the LED lamp pearl that each is single concentrates in the scope of the about 48 degree solid angles in the place ahead effectively, and whole light energies of efficiently utilizing LED lamp pearl are arranged.And can obtain even illuminance, the face to be illuminated with (preceding) side under the LED lamp pearl combination lamp throws light on equably.
