The utility model is described in further detail below in conjunction with drawings and Examples, in the accompanying drawing:

Fig. 1 is the structural representation that the utility model can be realized an embodiment of the LED lamp that angle changes;

Fig. 2 is the cross-sectional schematic that the utility model can be realized an embodiment of the LED lamp that angle changes;

Fig. 3 is that the utility model can realize that an embodiment of the LED lamp that angle changes adopts the schematic diagram of dull and stereotyped transmission element.

The specific embodiment

As shown in Figure 1, 2, be an embodiment who realizes the LED lamp that angle changes of the present utility model, comprise lamp socket 1, casing assembly, led light source 4, transparent lamp shade 7 etc.In addition, can also power supply 8 be installed in casing assembly as required, this power supply 8 is connected power supply with led light source 4.Further, also by adjustment structure lens 5 are set in the open side of casing assembly, to regulate the rising angle of led light source 4.

As shown in the figure, this lamp socket 1 adopts the spiral shell shell, is connected with external power supply 8, and access power supply 8 is led light source 4 power supplies.Certainly, this lamp socket 1 can also be selected other interfaces, such as conventional interfaces such as E26/GU10/E14/B22.

The radiation shell 3 that this casing assembly comprises support 2 and is arranged on support 2 peripheries.This support 2 is used for for installations such as led light source 4, adjustment structures, and as the support member of whole LED lamp, its shape and structure etc. can design as required.

This radiation shell 3 is fixedly installed on the periphery of support 2, and radiation shell 3 can design as required with the fixed form of support 2.In the present embodiment, the light transmittance of this radiation shell 3 is more than 90%, and adopts insulating materials to make, and can play thermolysis, also can play will reflection the light effect of dispelling the heat and sending.Certainly, radiation shell 3 can use full impregnated light or light tight material to make as required.

At lens 5 peripheral sheathed transparent lamp shades 7, the light that utilizes 7 pairs of LED lamps of transparent lamp shade to send carries out scattering, so that the rising angle excursion of whole LED lamp is: 24 °-360 °, form non-directionality lamp.Further, the light output surface of this transparent lamp shade 7 is provided with the diffusing structure of divergent rays, such as fin, salient point etc.

And light is reflected back radiation shell 3 by transparent lamp shade 7, and because radiation shell 3 is 80% above light transmittance, the light that is reflected back radiation shell 3 is sent by radiation shell 3 again, thereby rising angle is increased, and better forms non-directionality lamp.

As shown in the figure, this transparent lamp shade 7 is for the ball bubble, by the removable open side that is installed in casing assembly of syndeton.In the present embodiment, this syndeton is catching groove and the trip that arranges between transparent lamp shade 7 and connector 6, transparent lamp shade 7 is fastened on the open side of casing assembly.During assembling, utilize trip to buckle into catching groove, thereby with transparent lamp shade 7 dismountable being installed on the casing assembly.

The adjustment structure of the present embodiment comprises the connector 6 of the open side that is installed in described casing assembly.This connector 6 is fixedly mounted on the casing assembly by buckle structure, and as shown in the figure, this buckle structure is included in the outward extending flange in open side edge of support 2 and connector 6 to the buckle of downward-extension.Collude the edge that is located at support 2 by buckle, thereby connector 6 is fixed on the open side of casing assembly.Certainly, the connected mode between connector 6 and the casing assembly can also adopt existing variety of way, and such as adopting the variety of ways such as bolt, screw, rivet, welding, directly calcaneus branches frame 2 is fixedly connected with, also can be fixedly connected with radiation shell 3.

Be provided with screw thread pair between the outer ring of the inner ring of this connector 6 and lens 5, as shown in the figure, the inner ring of this connector 6 is provided with internal thread, the outer ring of lens 5 is provided with external screw thread, cooperation by screw thread pair, rotate lens 5 so that lens 5 can realize near or away from led light source 4, thereby realize the adjustment of rising angle.Certainly, internal thread also can be arranged on the outer ring of lens 5, and external screw thread is arranged on the inner ring of connector 6, can realize equally the position adjustment of lens 5.Understandable, adjustment structure can also adopt other forms, and for example grooved rail structure, retaining structure etc. are as long as can realize adjusting distance between lens 5 and the led light source 4.

In the present embodiment, this led light source 4 is selected 36 ° of led light sources 4; And these lens 5 are arranged on the outside of led light source 4, are provided with the pit 51 that holds led light source 4, and are provided with hemispherical projections 52 in the bottom of pit 51, with the bright dipping of diffusion led light source 4.

Regulate mobile lens 5, the directionality lamp can be adjusted to 120 ° of bright dippings, thereby adapt to the demand of different occasions.Certainly, the direct rising angle of led light source 4 can be selected arbitrarily, such as 10 °-60 °; Can focus by mobile lens 5 changes LED lamp angle, makes its excursion between 24 °-120 °.

As shown in Figure 3, further, when transparent lamp shade 7 not being installed, can also dull and stereotyped transmission element 9 be installed in lens 5 outsides, with the led light source 4 in the protecting sheathing assembly, power supply 8 etc.

During assembling, power supply 8 is installed in the support 2 of casing assembly, and led light source 4 is installed in the open side of support 2, so that power supply 8 is electrically connected with led light source 4; Then, with radiation shell 3 lamp socket 1, support 2, led light source 4 etc. are wrapped in wherein, and connector 6 are fastened on the open side of casing assembly; Then, lens 5 are screwed in connectors 6, and utilize screw thread pair to adjust distance between lens 5 and the led light source 4, can form the assembling of directionality lamp.

When needs are adjusted the rising angle of LED lamp, can adjust distance between lens 5 and the led light source 4 by rotating lens 5, obtain different rising angles, adapt to the use of different occasions.

Further, when the non-directionality lamp of needs occasion, transparent lamp shade 7 is fastened on the connector 6, transparent lamp shade 7 is set in the open side of casing assembly, the light that utilizes the LED lamp to send carries out diffuse reflection in transparent lamp shade 7; And light is reflected back radiation shell 3 by transparent lamp shade 7, and the light that is reflected back radiation shell 3 is sent by radiation shell 3 again, thereby rising angle is increased, and forms non-directionality lamp, to adapt to the use of non-directionality lamp occasion.

Directly dismounting of transparent lamp shade 7 of the present utility model is non-directionality lamp when transparent lamp shade 7 is installed, and is the directionality lamp when removing transparent lamp shade 7, can realize that both transform; Directly dismounting of lens 5; Led light source 4 is installed for modularization, can change according to actual needs.
