Description

The lamp holder improvement structure of light emitting diode road lamp

Technical field

The utility model is relevant for a kind of light emitting diode (LED) lamp, especially a kind of holder structure of LED street lamp.

Background technology

The known mercury street lamp that is used to throw light on, because the long-time high heat capacity that produces down that uses easily makes shorten the service life of bulb, power consumption is high and do not meet environmental protection requirement, so being had light emitting diode (LED, the Light Emitting Diode) light fixture of plurality of advantages such as brightness height, power saving, life-span length gradually replaces.

Be applied to the LED street lamp that outdoor lighting uses and be used as the purposes of guiding pedestrian or vehicle, certain distance is arranged between street lamp, also can reduce cost on the other hand in a jumble to avoid setting up too much street lamp can allow the appearance of the city seem; Yet, the present zone that but often exists street lamp not project on the Ordinary Rd, severe patient even may influence the safety of pedestrian or vehicle.

Exist a reason of field of illumination not to be the angle of street lamp lamp socket and lamp stand between street lamp; Shown in Figure 1A, schematic diagram for present illuminating street lamp, comprise lamp stand 1, arm 2 and lamp socket group 3, this arm 2 is X with the angle of lamp stand 1, generally between 101 degree are spent to 105, under this angle X, the irradiated area that lamp socket group 3 is incident upon ground is A, please consult Figure 1B in addition, when the angle of arm 2 and lamp stand 1 is increased to Y by X, because changed the direction of lamp socket group 3 toward the ground projection, lamp socket group 3 is incident upon the irradiated area on ground and promptly expands as area B by area A, can improve in view of the above to have the not problem of field of illumination between street lamp.

In above-mentioned, change lamp socket group 3 is to change lamp stand 1 and arm 2 toward the direction of ground projection angle; But, the lamp stand 1 of general street lamp is what fix with the angle of arm 2, the angle that desire changes lamp stand 1 and arm 2 then need re-establish lamp stand 1 and arm 2, this measure will spend a large amount of money, manpower and time, especially street lamp belongs to communal facility, replaces the misgivings that numerous lamp stands 1 easily have waste public expense; Therefore, how under the angle of former lamp stand 1 and arm 2, to change lamp socket group 3 direction of projection earthward, be the current problem of studying of the utility model.

The utility model content

In view of this, main purpose of the present utility model is to provide a kind of lamp holder improvement structure of LED street lamp, can improve to have the not problem of field of illumination between street lamp, can save the huge expense of displacement street lamp post.

In order to reach above-mentioned purpose, the utility model provides a kind of lamp holder improvement structure of LED street lamp, comprise that mainly inside forms the lamp socket of two or more light troughs, light trough has vertical bottom surface that is inclined to set with respect to the plane of light-passing board, corresponding light trough and be provided with light emitting module along its bottom surface in the lamp socket, light-passing board connects lamp socket with two groups or more light emitting module of involution cover cap.

As can be seen from the above technical solutions, the lamp holder improvement structure of LED street lamp of the present utility model because the light trough in the lamp socket is provided with the bottom surface that is fore-and-aft tilt, need re-establish lamp stand and arm and can change LED street lamp projecting direction; Whereby, provide the lighting device that can change projecting direction, improve and have the not problem of field of illumination between street lamp, and can save the huge expense of displacement street lamp post.

The specific embodiment

Relevant detailed description of the present utility model and technology contents, conjunction with figs. is described as follows, however appended accompanying drawing only provides reference and explanation usefulness, is not to be used for the utility model is limited.

Please refer to Fig. 2 to Fig. 5, the utility model provides a kind of lamp holder improvement structure of LED street lamp, comprises lamp socket 10, two groups or more light emitting module 20 and light-passing board 30; This lamp socket 10 is made of die casting aluminium, and the outside of lamp socket 10 forms two or more fin 11, and lamp socket 10 inside form two or more and are the light trough 12 (as shown in Figure 4) that matrix is arranged, and this light trough 12 can be bowl-type or ladder-shaper structure; Wherein, the longitudinally stepped light trough 12 that is provided with of lamp socket 10, lamp socket 10 laterally be provided with at least three bank light grooves 12 (ginseng Fig. 3 and Fig. 5), this left and right bank light groove 12 tilts to increase poly-optical activity in lamp socket; In the present embodiment, form nine light troughs 12 in this lamp socket 10, in each light trough 12 respectively correspondence be provided with one group of light emitting module 20, during actual enforcement, can be in the lamp socket 10 according to the quantity of required adjustment light emitting module 20 light troughs 12 pairing with it.

This light emitting module 20 includes pedestal 21, substrate 22, luminescence unit 23, reflection lampshade 24 and transmissive mirror 25; Pedestal 21 is located on the bottom surface 121 of light trough 12, substrate 22 is located on the pedestal 21, be connected with the luminescence unit 23 that comprises two or more light emitting diodes 231 on the substrate 22, has storage tank 241 in the reflection lampshade 24 to be installed with this luminescence unit 23, affixed this pedestal 21 of one end of reflection lampshade 24, the other end then involution has transmissive mirror 25, wherein, this transmissive mirror 25 can be made as Fresnel Lenses (Fresnel Lens) to increase the poly-optical activity of light emitting module 20, this transmissive mirror 25 cooperates the design of reflection lampshades 24, the angles of adjustable optical module 20 projection downwards of haircuting and increase the zone of effective light projector.In the said structure, because of pedestal 21 is established along the bottom surface 121 of light trough 12, so the light emitting module 20 that is combined on the pedestal 21 also is arranged in the lamp socket 10 along the bottom surface 121 of light trough 12, in addition, light-passing board 30 with plane is set on this lamp socket 10, light-passing board 30 for two groups or more light emitting modules 20 of involution cover cap to prevent light fixtures in the lamp socket 10 and make moist and to damage; Wherein, the bottom surface 121 of the light trough 12 in this lamp socket 10 vertically is inclined to set with respect to light-passing board 30.
