The specific embodiment
As shown in Figure 1 to Figure 3, a kind of LED light fixture 10 that the present invention's the first preferred embodiment provides, mainly be comprised of a cooling base 11 and a plurality of lamp bar 21, wherein:
This cooling base 11, to be shaped and to form by aluminium extruded type, and the direction that its aluminium extruded type is shaped is defined as its length direction, this cooling base 11 has a main body 12 and a plurality of radiating fin 14, these main body 12 bottom sides have a joint face 13, this joint face 13 is to be tabular surface, and described radiating fin 14 is to be stretched out and formed by this main body 12.
Described lamp bar 21, be that to take four lamp bars 21 be example in the present embodiment, respectively has a circuit board 22 and be located at least one LED module 23 on this circuit board 22, and respectively this circuit board 22 of this lamp bar 21 is these joint faces 13 of being located at this cooling base 11.In this first embodiment, be to take on this circuit board 22 to there is a plurality of LED module 23 as example, yet, also a LED module 23 can only be set on of the present invention one this circuit board 22, so that being set, a plurality of LED modules 23 are not limited.In addition, in this first embodiment, described lamp bar 21 is to be locked on this joint face 13 by bolt 92.
Wherein, joint face 13 width of this cooling base 11 are W1, and the width of described lamp bar 21 is W2, and W1>3W2.
According to above structure, due to this joint face 13, be to be tabular surface, representing on this joint face 13 and there is no to arrange the caulking groove as known technology, therefore be directly described lamp bar 21 position designed according to the producer to be arranged to this joint face 13, so, can not be subject to the restriction of the caulking groove of known technology, arrange more convenient and have more elasticity.Therefore in addition, while wanting to set up lamp bar 21, due to the restriction that is not subject to caulking groove, do not need the length of extension housing (being cooling base 11), but the place that only need still have living space is set up lamp bar 21 and is got final product on this joint face 13.
Again, the definition of aforesaid W1>3W2, be mainly can be set up in parallel three lamp bars 21 or more lamp bars 21 in order to define on this joint face 13 on width.Though shows two lamp bars 21 only are set on width in Fig. 2, but this is only for example, and three lamp bars 21 or more lamp bars also can be set.
As from the foregoing, this first embodiment can allow arrangement mode, the position of LED lamp group can not be subject to caulking groove and limit, and makes the magnitude setting of LED lamp group more not be restricted.In addition, this first embodiment also can improve in known technology, and the aluminium extruded type light fixture can only increase and decrease the problem of LED lamp group in the longitudinal direction, in other words, this first embodiment not only can increase and decrease LED lamp group in the longitudinal direction, also can on width, increase and decrease LED lamp group.
Please consult Fig. 4 to Fig. 9, a kind of LED light fixture 30 that the present invention's the second preferred embodiment provides, take off the first embodiment before mainly generally being same as again, and difference is:
More to define W1>3W2+12.8mm (millimeter).Owing in safety standard, must considering the clearance issues between lamp bar 41, so the width of this joint face 33 must be wider, and the width of the 12.8mm increased in the present embodiment is mainly set for the clearance issues of safety standard.
Secondly, be that the width that more defines this cooling base 31 is W3, and 140mm<W3<250mm.Under the condition of considering heat-sinking capability and cost, such width dimensions is the advantage that the board while having heat-sinking capability and aluminium extruded type shaping concurrently is big or small, push the manufacturing costs such as pressure.
With the present embodiment, the width W 1 of this joint face 33 is 132mm, and the width W 2 of lamp bar 41 is 19mm, and the width W 3 of this cooling base 31 is 150mm; Meeting under the front topic of above-mentioned relation formula, these width W 1, W2, W3 all can freely be changed.
