Abstract

The utility model relates to an improved structure of light-emitting diode lamp group, comprising a carriage, a lantern case, an equal mill finish and a base plate, wherein the lantern case is arranged on one side of the carriage which is connected with a power supply device to provide power for the LBD of the base plate; the equal mill finish is provided with a plurality of wales, the wales diffuse outwards from the center of the equal mill finish and assume a concentric shape, and the outline around or one side of the equal mill finish can be surrounded with the base plate. Therefore the light source emitted by the LBD can reflect to the equal mill finish, and the wales can be used to make the light source refract or reflect to equally emit the light source.

Description

LED light lamp group structure-improved

The utility model relates to a kind of light emitting diode (LED) lamp group structure-improved, relates in particular to a kind of applicable traffic lights etc., and has the lamp group of uniform source of light effect.

As shown in Figure 1, it is a kind of known lamp group, this lamp group 1a is applied to traffic lights such as traffic lights, comprise a bracing frame 10a, a lamp door 11a and one group of illuminator 12a: wherein, this bracing frame 10a is fixedly set in the position that desire is provided with, the side of lamp door 11a then is located on the support arm 13a that this bracing frame 10a extended, and this lamp door 11a is provided with above-mentioned illuminator 12a, and the light source that is throwed by illuminator 12a reaches its purpose.

Yet, above-mentioned known lamp group, because of light source directly is incident upon on the lamp door, and because light source is that therefore the light-source brightness that is produced is inhomogeneous, so not only makes the light source of direct projection cause human eye's injury, and can't reach the effect of uniform source of light to diffusion all around.

So as from the foregoing, above-mentioned known lamp group on reality is used, obviously has inconvenience and exists with shortcoming, and await being improved.

Main purpose of the present utility model is to provide a kind of decorative LED lamp group, and it is to utilize the principle of refraction or reflection so that light source shines equably, produces to avoid known shortcoming.

In order to finish above-mentioned purpose, the utility model provides a kind of decorative LED lamp group, comprises a bracing frame, a lamp door, all a light face and a substrate; This lamp door is to be located on the side of bracing frame, and this bracing frame links a supply unit, so that the required power supply of these light emitting diodes of aforesaid substrate to be provided, in addition, this all the light face be provided with a plurality of burrs, these burrs are to be concentric shape by equal centers of light face to external diffusion, but and this all the periphery contour or the one side substrate ring of light face are established; Whereby, make light source projects that these light emitting diodes send on equal light faces, and utilize these burrs to make light source produce the phenomenon of refraction or reflection, so that light source is penetrated equably.

In order to illustrate further feature of the present utility model and technology contents, see also following about detailed description of the present utility model and accompanying drawing, yet appended graphic only provide with reference to and the explanation usefulness, be not to be used for the utility model is limited.

Fig. 1 is the floor map of lamps known group.

Fig. 2 is a perspective exploded view of the present utility model.

Fig. 2 A is the A part enlarged detail of Fig. 2.

Fig. 3 is a three-dimensional combination schematic diagram of the present utility model.

See also Fig. 2 and Fig. 3, it is respectively perspective exploded view of the present utility model and three-dimensional combination schematic diagram.The utility model provides a kind of decorative LED lamp group, comprises a bracing frame 1, a lamp door 2, all a light face 3 and a substrate 4; Wherein, this bracing frame 1 is as the purposes that supports, and links a supply unit (figure slightly), and this supply unit (figure slightly) can provide power supply with as luminous required of lamp group, the conducting that also can pass through a switch (figure slightly) control power supply whether, to open or to close this supply unit (figure is slightly); In addition, the side at this bracing frame 1 forms a support arm 10.

This lamp door 2 is to be arranged on the support arm 10 of bracing frame 1, and the actual demand of visual this lamp group and as traffic lights etc.

This all light face 3 be can glass, polyacrylate or Merlon material transparent such as (PC) be made, and is provided with a plurality of burrs 30 (shown in Fig. 2 A), these burrs 30 are to be concentric shape by equal centers of light face 3 to external diffusion.

This substrate 4 is provided with a plurality of light emitting diodes 40, and these light emitting diodes 40 are to arrange along the inner edge equal distribution of this substrate 4, and is connected with the supply unit (figure slightly) of bracing frame 1, to supply with the required electric power of these light-emittingdiodes 40; In addition, this substrate 4 is located on the peripheral outline or one side of equal light faces 3; And by above-mentioned structure, get final product a decorative LED lamp group of the present utility model.

When light source projects that these light emitting diodes 40 send in this all on the light face 3 time, these burrs 30 can make light source produce the phenomenon of refraction or reflection, and light source done all processing of light, to penetrate by 3 refractions of equal light faces or reflection equably, so oneself comparatively relaxes its emitted light source, therefore, can't the eyes of human body be damaged, and can reach the effect of uniform source of light.

In addition, this all can be provided with the background of different colours on the dorsal surface of light face 3, so that the light source projects that these light emitting diodes 40 are sent all on the light face 3 time, can present different colors in this, sets to cooperate the color that traffic lights need present.

Again, the light source that all light emitting diodes 40 of on this substrate 4 this are sent continues the illumination of projection except doing, the light source that these light emitting diodes 40 are sent also this substrate 4 can be laid with the IC circuit or the chip of programmable, so that can be done the flicker of ad hoc fashion.

Moreover the light source that all light emitting diodes 40 of this on this substrate 4 are sent also can be the light of multiple different colours, and these all light emitting diodes 40 can fix light, flicker, single flicker or variation such as flicker in turn.

The above only is a preferable possible embodiments of the present utility model; non-so promptly limit claim scope of the present utility model; so the equivalent structure that every utilization the utility model specification and accompanying drawing content are done changes; all in like manner all be contained in the protection domain of claim of the present utility model, close and give Chen Ming.
