Description

The LED wick that is used for street lamp

Technical field

The utility model relates to lighting technical field, specifically is a kind of LED wick that is used for street lamp.

Background technology

At present, because the power of LED street lamp is big, the requirement height of heat radiation, thus use LED all need require to re-design according to heat radiation as the street lamp of light source, like this, one, in order to improve area of dissipation, strengthen radiating effect, the structural design of existing LED street lamp is complicated, cost is higher, such as radiator structure is set on lampshade in large quantities; Two, can't use the lampshade of original street lamp, not only increased improvement cost greatly, and it is low to transform efficient to original street lamp, promptly when transforming, must at first remove original street lamp.

The utility model content

The technical problems to be solved in the utility model is, provide a kind of and not only have good performance of heat dissipation, and simple in structure, cost is low, the convenient LED wick that is used for street lamp of transforming original street lamp.

The technical solution of the utility model is, a kind of LED wick that is used for street lamp with following structure is provided, it comprises wiring board and settles in the circuit board LED, and it also comprises first support member that is used for being connected and using base that heat sink material makes with the protecgulum of the lampshade of original street lamp, is used to settle wiring board and use heat sink material to make, be used to support a plurality of second support members that first support member and use heat sink material make, be arranged at least one radiating piece between the base and first support member; One end of described second support member is connected with first support member, and the other end of second support member is connected with base, has spacing between adjacent second support member; One end of described radiating piece is connected with first support member, and the other end of radiating piece is connected with base.

After adopting said structure, the utility model compared with prior art, have the following advantages: because adopted described base, first support member, second support member, radiating piece, so the utlity model has enough area of dissipations, and because have spacing between adjacent second support member, so extraneous air just can enter between the base and first support member, strengthen cross-ventilation, flow air can promptly be taken away the heat on base, first support member, second support member, the radiating piece, makes to the utlity model has good performance of heat dissipation; Based on above-mentioned good performance of heat dissipation, only need described LED wick is fixed on the transformation that can finish on the lampshade of original street lamp original street lamp reliably, as seen very convenient, if original street lamp has the cover of printing opacity, only needs are removed the cover of this printing opacity earlier, described LED wick are loaded onto to get final product again, like this, greatly reduce improvement cost, and transform the efficient height original street lamp; Because the utility model parts are less, annexation is simple, so the utility model is simple in structure, production cost is low.Comprehensively above-mentioned, the utility model not only has the advantage of good performance of heat dissipation, and has advantage simple in structure, that cost is low, convenience is transformed original street lamp.

As improvement; it also comprises wiring board and settles in the circuit board LED to play the transmission element of seal protection effect; the described transmission element and second support member are tightly connected; like this; one comes wiring board and arrangement LED (LED bulb or fluorescent tube) are in the circuit board played the better protect effect; two help protecting user's safety, satisfy relevant authentications such as IP quality authentication.

As further improvement, described heat sink material is an aluminium, because the metallic aluminium cost performance is outstanding, and lighter weight, so more help the raising of the utility model performance.

As further improvement, described radiating piece is to make the fin that is formed from aluminium; Described radiating piece is a plurality of, has spacing between the adjacent radiating piece; Like this, because fin has bigger area of dissipation, be typical radiating piece, and be a kind of aluminium section bar, can buy easily, so help improving heat dispersion, reduce production costs, and, there is spacing in adjacent radiating piece, like this, just there is the passage that flows through for air in adjacent radiating piece, more helps improving heat dispersion of the present utility model.

The specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing.

The utility model is used for the LED wick of street lamp, it comprises wiring board 1 and is placed in LED 2 on the wiring board 1, and it also comprises and be used for being connected and using base 4 that heat sink material makes with the protecgulum 3.1 of the lampshade 3 of original street lamp, be used to settle wiring board 1 and use first support member 5 that heat sink material makes, be used to support first support member 5 and use a plurality of second support members 6 that heat sink material makes, be arranged at least one radiating piece 7 between the base 4 and first support member 5; In this example, described second support member 6 is four, and an end of described second support member 6 is connected with first support member 5, and the other end of second support member 6 is connected with base 4, has spacing between adjacent second support member 6; One end of described radiating piece 7 is connected with first support member 5, and the other end of radiating piece 7 is connected with base 4.Concrete structure is shown in Fig. 1 or 2.

In this example, described LED 2 is LED bulb commonly used.

The protecgulum 3.1 of described base 4 and the lampshade 3 of original street lamp is by being spirally connected or prior art such as welding is connected.

It comprises also to wiring board 1 and is placed in the transmission element 8 that LED 2 on the wiring board 1 plays the seal protection effect that the described transmission element 8 and first support member 5 are tightly connected.Described transmission element 8 is a transparent cover plate; it will cover wiring board 1 and be placed in LED 2 on the wiring board 1; thereby wiring board 1 and the LED 2 that is placed on the wiring board 1 are carried out seal protection, and described being tightly connected can adopt sealing strip or other prior aries to realize.

For the ease of knowing figure, except drawn wiring board 1 and being placed in the LED 2 on the wiring board 1 in Fig. 1, though transmission element 8 is transparent, wiring board 1 and be placed in LED 2 on the wiring board 1 does not all draw in Fig. 2 or Fig. 3 or Fig. 4.

Described heat sink material is an aluminium.
