Abstract

The utility model discloses an LED street lamp which comprises LEDs, a placing plate and a lamp cap, wherein the placing plate and the lamp cap are fixed together, the LEDs are densely installed on the placing plate, the middle part of the placing plate is provided with a flat panel, the periphery of the placing plate is tilted in an opposite direction of the installation surface of the LEDs and an included angle is formed, and the installation surface of the LEDs is in a protrusion shape. When the LEDs are installed on the protruded installation surface, all LEDs are distributed on the protruded tabletop rather than a plane of the prior art, and thus the LED street lamp has the advantages of large irradiation angle, high brightness, small electric energy consumption and long service life of LEDs.

Description

The LED street lamp

Technical field

The utility model relates to the technical field of LED street lamp, and especially to lay plate structure relevant with the LED of LED street lamp.

Background technology

Existing LED street lamp comprises LED1 ', lays plate 2 ' and lamp holder 3 ' is formed, and lays plate 2 ' and lamp holder 3 ' and is fixed together, and LED1 ' is intensive the laying on the plate 2 ' (PCB) an of plane of being installed in, shown in Fig. 1,2 and 3.Because LED1 ' has fixing irradiating angle θ, be generally (super bright) about 15 °, be no more than 30 °, so, when LED1 ' is intensive when being installed in the laying plate 2 ' and go up of plane, limited by LED irradiating angle θ, the irradiating angle β of street lamp is little, the irradiation diameter can only reach 4 meters, and the irradiation diameter of national regulation street lamp should reach more than 6 meters at least, for head it off, the technical staff adopts the LED of large illuminating angle degree θ ' usually as far as possible in the industry, still, LED is in the certain situation of power, increase angle, will lose brightness (mcd), make the road illumination of whole LED street lamp (see the city illumination design standard for details) more than the 15Lux less than national regulation again; The technical staff who also has adopts LED high-power, wide-angle, but the volume of this type LED street lamp is big, and the installing space of street lamp is limited, make the intensive number of laying on the plate 2 ' that is installed in of LED1 ' reduce, influence the brightness of LED street lamp again, and, high-power increase, consumed power increases thereupon, can not reach economical, energy-conservation purpose, in addition, the plane plate of laying, LED concentrates in together, and has heat dissipation problem, also directly influences the LED life-span.

The utility model content

The purpose of this utility model is to provide a kind of LED street lamp, so that the range of exposures of LED street lamp is wide, illumination range is big and consumed power is little, the LED life-span prolongs.

For reaching above-mentioned purpose, solution of the present utility model is:

The LED street lamp comprises LED, lays plate and lamp holder and form, and lays plate and lamp holder is fixed together, LED is that intensive being installed in laid on the plate, wherein, lays the plate middle part and is surface plate, periphery forms angle to the perk in the other direction of the installed surface of LED, makes the installation of LED and is convex.

The above-mentioned plate of laying is spliced by a surface plate and a peripheral surface plate at middle part at least, forms angle between the surface plate of periphery and the surface plate at middle part, makes the installed surface of LED be convex.

The above-mentioned plate of laying is spliced by surface plate at middle part and four surface plates of periphery, and four surface plates of periphery all form angle with that piece surface plate at middle part, make the installed surface of LED be convex.

Form 10 °-15 ° angle between the surface plate at the above-mentioned surface plate of laying the plate periphery and middle part.

After adopting said structure, the utility model is convex owing to will lay the installed surface of onboard led by plane improvement design of the prior art, so, after LED is installed on this protruding installed surface, form angle owing to lay the periphery of plate to the opposite direction perk of LED installed surface, so all LED are distributed on the table top of projection, but not on the plane of prior art, the street lamp irradiating angle β that is constituted increases relatively, only need to install general illumination angle θ (10 °-30 °), low power LED, can make the irradiation diameter of street lamp reach 6 meters, brightness (vertical ground illumination) reaches more than the 20Lux, meet national regulation, and, small-power, low-angle LED volume is little, in the scope that can allow at the installing space of LED street lamp, laying the enough LED of installation on the plate, the volume that had both guaranteed street lamp is little, guarantee the brightness of LED street lamp again, and power is less, consumed power is also little, more economical, energy-conservation, in addition, LED is installed on the table top of projection, help heat dissipation problem, the LED life-span is prolonged.

The specific embodiment

Shown in Fig. 4,5 and 6, the LED street lamp that the utility model discloses, comprise LED1, lay plate 2 and lamp holder 3 compositions, lay plate 2 and lamp holder 3 is fixed together, LED1 is that intensive being installed in laid on the plate 2, the key of this case is: laying plate 2 middle parts is surface plate, and periphery forms angle γ to the installed surface perk in the other direction of LED1, makes the installed surface of LED1 be convex.

Specifically, be to lay the peripheral perk of plate 2, such as direct one-body molded peripheral perk lay plate (this paper does not do diagram), total is come out by the mould pressure injection of dimensionally stable; Or lay plate 2 and be spliced by a surface plate at middle part and a surface plate of periphery at least, form angle between the surface plate of periphery and the surface plate at middle part, wherein, being spliced with the surface plate of the surface plate at a middle part and four peripheries, to lay plate 2 be optimal morphology, be optimal morphology to form 10 °-15 ° angle γ between the surface plate of periphery and the surface plate at middle part, like this, promptly make the installed surface of LED1 be convex.

Cooperate shown in Figure 6, owing to lay the change of plate 2 shapes, the plate 2 ' of laying of the relative prior art of irradiating angle β of the LED street lamp that constitutes obviously increases, so, only need to install general illumination angle θ (10 °-30 °), low power LED1, can make the irradiation diameter of street lamp reach 6 meters, brightness (vertical ground illumination) and reach more than the 20Lux, meet national Specification.And small-power, low-angle LED1 volume are little, in the scope that can allow at the installing space of LED street lamp, laying the enough LED1 of installation on the plate 2, both guaranteed that the volume of street lamp was little, guarantee the brightness of LED street lamp again, and, power is less, and consumed power is also little, and is more economical, energy-conservation, in addition, LED is installed on the table top of projection, helps heat dissipation problem, and the LED life-span is prolonged.
