Abstract
The suspention lamp that a kind of light efficiency is good, comprising cross section is half elliptic reflection cap, and described reflection cap both sides extend internally and are provided with installing plate, and described installing plate and reflection cap are integrated drawing and forming, described installing plate is positioned on oval major axis, and the major axis of described ellipse is the twice of minor axis length; Described installing plate is provided with LED-baseplate, and described LED-baseplate is provided with LED chip; Reflection cap inner surface forms reflector space, and below reflection cap, both sides form light-emitting zone, and the region in the middle of below reflection cap between two installing plates is bright dipping region, is provided with diffuser plate in described bright dipping region.Below reflection cap, both sides are respectively equipped with light source, so can increase the luminescence of suspention lamp both sides, fill up the shortcoming that existing suspention lamp both sides light is more weak; Below reflection cap, the LED light source of both sides carries out light reflection by reflection cap, and then reflection ray irradiates by bright dipping region, and LED light line is when reflection, and light is broken up, and emergent ray is become and is uniformly dispersed.
Description
Technical field
The utility model relates to field of LED illumination, the suspention lamp that especially a kind of light efficiency is good.
Background technology
Suspention lamp, as the term suggests be suspend in midair on the ceiling, is used for room lighting.It generally comprises face shield, reflector and LED substrate mount pad, and existing reflector and substrate installing plate are separate, thus causes its production cost to increase, and fitting structure both dismounting process is comparatively complicated.In addition the reflector of existing suspention lamp and LED rising angle unreasonable, often cause suspention light utilization rate low, and illumination is even not; And its LED light source direct irradiation face shield, directly can see LED chip by face shield, to a certain extent the aesthetic property of impact suspention lamp.
Summary of the invention
Technical problem to be solved in the utility model is to provide the good suspention lamp of a kind of light efficiency, and structure is simple, and uniform in light emission, can't see LED chip, more attractive in appearance.
For solving the problems of the technologies described above, the technical solution of the utility model is: the suspention lamp that a kind of light efficiency is good, comprising cross section is half elliptic reflection cap, described reflection cap both sides extend internally and are provided with installing plate, described installing plate and reflection cap are integrated drawing and forming, described installing plate is positioned on oval major axis, and the major axis of described ellipse is the twice of minor axis length; Described installing plate is provided with LED-baseplate, and described LED-baseplate is provided with LED chip; Reflection cap inner surface forms reflector space, and below reflection cap, both sides form light-emitting zone, and the region in the middle of below reflection cap between two installing plates is bright dipping region, is provided with diffuser plate in described bright dipping region.Below reflection cap, both sides are respectively equipped with light source, so can increase the luminescence of suspention lamp both sides, fill up the shortcoming that existing suspention lamp both sides light is more weak; Below reflection cap, the LED light source of both sides carries out light reflection by reflection cap, and then reflection ray irradiates by bright dipping region, and LED light line is when reflection, and light is broken up, and emergent ray is become and is uniformly dispersed; Emergent light is after the diffuser plate in bright dipping region, and emergent ray is disperseed further, improves the uniformity of bright dipping; Oval reflection cap, makes the light reflection angle being positioned at the LED light source on transverse larger, try one's best by the light of both sides toward middle bright dipping regional reflex, improve light extraction efficiency; Because LED-baseplate is positioned at the below of LED chip, LED chip is hidden between LED-baseplate and reflection cap, and the aesthetic property of suspention lamp is better.
As improvement, the major axis of described ellipse is 110 ~ 130mm.
As improvement, described LED chip is along suspention lamp length direction word order.
As improvement, described reflection cap two ends are provided with shrouding.
The beneficial effect that the utility model is compared with prior art brought is:
1, below reflection cap, both sides are respectively equipped with light source, so can increase the luminescence of suspention lamp both sides, fill up the shortcoming that existing suspention lamp both sides light is more weak;
2, below reflection cap, the LED light source of both sides carries out light reflection by reflection cap, and then reflection ray irradiates by bright dipping region, and LED light line is when reflection, and light is broken up, and emergent ray is become and is uniformly dispersed;
3, emergent light is after the diffuser plate in bright dipping region, and emergent ray is disperseed further, improves the uniformity of bright dipping;
4, oval reflection cap, makes the light reflection angle being positioned at the LED light source on transverse larger, try one's best by the light of both sides toward middle bright dipping regional reflex, improve light extraction efficiency;
5, because LED-baseplate is positioned at the below of LED chip, LED chip is hidden between LED-baseplate and reflection cap, and the aesthetic property of suspention lamp is better.

Detailed description of the invention
Below in conjunction with Figure of description, the utility model is described in further detail.
As shown in Fig. 1,2,4, a kind of suspention lamp of uniform in light emission, comprising cross section is half elliptic reflection cap 1, described reflection cap 1 both sides extend internally and are provided with installing plate 2, described installing plate 2 is integrated drawing and forming with reflection cap 1, makes its structure simpler, installs more convenient.Described installing plate 2 is positioned on oval major axis, and the major axis of described ellipse is the twice of minor axis length, in the present embodiment, and the long 110 ~ 130mm of oval major axis.Described installing plate 2 is provided with LED-baseplate 3, and LED-baseplate 3 is in strip, and described LED-baseplate 3 is provided with LED chip 4, and described LED chip 4 is along suspention lamp length direction word order.As shown in Figure 3,4, reflection cap 1 inner surface forms reflector space 5, and below reflection cap 1, both sides form light-emitting zone 6, and the region in the middle of below reflection cap 1 between two installing plates 2 is bright dipping region 7; Be provided with diffuser plate 8 in described bright dipping region 7, described installing plate 2 is provided with mounting groove 9 towards side, bright dipping region 7, and described diffuser plate 8 both sides are carried out installation by described mounting groove 9 and fixed.Described reflection cap 1 two ends are provided with shrouding (sign), can play the dust-proof effect with preventing light leak.
Below reflection cap 1, both sides are respectively equipped with light source, so can increase the luminescence of suspention lamp both sides, fill up the shortcoming that existing suspention lamp both sides light is more weak; Below reflection cap 1, the LED light source of both sides carries out light reflection by reflection cap 1, and then reflection ray irradiates by bright dipping region, and LED light line is when reflection, and light is broken up, and emergent ray is become and is uniformly dispersed; Emergent light is after the diffuser plate in bright dipping region, and emergent ray is disperseed further, improves the uniformity of bright dipping; Oval reflection cap 1, makes the light reflection angle being positioned at the LED light source on transverse larger, try one's best by the light of both sides toward middle bright dipping regional reflex, improve light extraction efficiency; Because LED-baseplate 3 is positioned at the below of LED chip 4, LED chip 4 is hidden between LED-baseplate 3 and reflection cap 1, and the aesthetic property of suspention lamp is better.
