As shown in Fig. 2-Fig. 8, a kind of LED lamp 200 (can be described as again LED support lamp), it extends into elongate shape in a longitudinal direction, comprises housing 202, support 204, diffuser 206, reflector 208, substrate 210, LED212 and end cap 214.
Particularly, as shown in Figure 5, this housing 202 is formed by sheet metal bending, its have diapire 2021 with from extended two the relative sidewalls 2022 of described diapire 2021 to form the roughly chamber 2023 of U-shaped, the edge of each sidewall 2022 forms guide rail 2024.This guide rail 2024 is barb-like substantially, via the edge of sidewall 2022 inwardly again bending downwards form, can comprise that the 2024a of 2024a He Cong first of first that laterally inwardly extends from the edge of sidewall 2022 is to the second portion 2024b of downward-extension.Each sidewall 2022 of this housing 202 also bends inwards and forms mounting groove 2025, for installing rack (not shown) is located thereon slidably, like this, installing rack just can slide into suitable installation site and housing 202 is installed on metope according to the specific installation environment of metope.Preferably, the diapire 2021 of this housing 202 also offers window, the terminal plate on it with electronic device is arranged on housing 202 with opening and closing of fault window, when terminal plate is fixed on housing 202 and during closed window, electronic device on terminal plate is accommodated in the chamber 2023 of housing 202 via window, when terminal plate moves apart from window, the electronic device on terminal plate exposes from window.
In conjunction with Fig. 4 and Fig. 6, support 204 is fixed in the chamber 2023 of housing 202.In view of the fluorescent tube that LED lamp 200 is lengthwise, can in exemplary embodiment, arrange three supports 204 at the several supports 204 of the interior layout of chamber 2023, and respectively near left side and the end cap 214 on right side and the intermediate arrangement of housing 202.This support 204 can be formed by the sheet metal bending such as aluminium alloy, and it has roughly inverted U-shaped shape.Particularly, this support 204 comprise two substantially parallel sidewalls 2041, respectively from the longitudinal outward in bottom of two sidewalls 2041 and and sidewall 2041 separately roughly L-shaped end wall 2042 and the roof 2043 between two sidewalls 2041, this end wall 2042 can be soldered on the diapire 2021 of housing 202.Preferably, the roof 2043 of this support 204 is bent with groove low between the senior middle school of both sides and low groove position also offers installing hole in centre.
As shown in Figure 7, the arc component that this diffuser 206 is lengthwise, it has main part 2061 and groove 2062, and this groove 2062 is formed on the edge respect to one another of main part 2061 both sides.Particularly, the relative position of main part 2061 and LED212 is configured to make LED212 to be roughly positioned at the center of circle of 2061 shapes in the arc-shaped of main part; This groove 2062 is continued to extend by the substantially inside horizontally extending 2062a He Cong 2062a of first of first in the edge from diffuser 206 and forms to form hook-shaped second portion 2062b.Wherein, the outer surface of the 2062a of first abuts the 2024a of first of the guide rail 2024 of housing 202 on vertically, the inner surface supporting reflex device 208 of the 2062a of first, the outer surface of second portion 2062b is for abutting in the horizontal the second portion 2024b of the guide rail 2024 of housing 202.By this, the 2024a of first of aforementioned guide rail 2024 coordinates and can play vertical spacing effect together with the 2062a of first of groove 2062, and the second portion 2024b of guide rail 2024 coordinates and can play cross spacing effect together with the second portion 2062b of groove 2062.Like this, diffuser 206 can be inserted into slidably guide rail 2024 and be navigated to reliably on housing 202 from one end of aforementioned housing 202.
As shown in Figure 8, reflector 208 can be formed and is fixed on support 204 in diffuser 206 by sheet metal.Particularly, reflector 208 comprises the main body reflecting part 2081 that roughly along continuous straight runs extends and the auxiliary reflecting part 2082 of roughly vertically extending.Wherein, main body reflecting part 2081 is roughly basin shape, it comprises diapire 2081a, sidewall 2081b and end wall 2081c, sidewall 2081b respectively from the lopsidedness of diapire 2081a stretch out and form, end wall 2081c further stretches out and forms from sidewall 2081b respectively.Auxiliary reflecting part 2082 is formed at the two ends of main body reflecting part 2081 and is contained in completely in end cap 214, and it is roughly fan-shaped.Further, a part of the diapire 2081a of this reflector 208 is sunk and is offered installing hole so that surperficial S1 form to be installed, and this is installed surperficial S1 and is greater than and through installing hole, reflector 208 is fastened to the height of the head of the securing member 216 on support 204 to the distance H of the upper surface S2 of other parts of diapire 2081a.When reflector 208 injects from one end of housing 202 while installing in diffuser 206, on the one hand, the part diapire that reflector 208 sinks is accommodated in groove low between the both sides senior middle school of roof 2043 of aforesaid support 204 and makes installing hole and the installing hole on support 204 that surperficial S1 is installed aim at simultaneously, and securing member 216 is fastened to reflector 208 on support 204; On the other hand, other parts of the diapire 2081a of reflector 208 abut to the both sides of the roof 2043 of support 204, and end wall 2081c supports on the 2062a of first of diffuser 206.
After aforesaid member installs, end cap 214 is fastened on to the end of housing 202 and diffuser 206 and makes end cap 214 cover in the auxiliary reflecting part 2082 of reflector 208 completely.Accordingly, be arranged in the light that the LED212 on substrate 210 sends and can not spill from end cap 214, when this can improve light efficiency, can also increase the overall aesthetic of LED lamp 200.
According to an aspect of the present utility model, because housing 202 and reflector 208 all can be formed by sheet metal bending, than prior art, material cost is minimized and is shaped and is more prone to.
According to another aspect of the present utility model, due to the novel structure of the guide rail 2024 of housing 202 and the groove 2062 of diffuser 206, cooperation is between the two safer, firm and convenient.In addition, the end wall 2081c of reflector 208 presses the 2062a of first that puts diffuser 206 above for diffuser 206 provides auxiliary safeguard protection.Moreover the interference that the assembling of reflector 208 and support 204 and substrate 210 has avoided securing member 216 to bring dexterously, can save space by this.
Technology contents of the present utility model and technical characterstic have disclosed as above; yet be appreciated that; under creative ideas of the present utility model; those skilled in the art can make various changes and improve said structure and shape; comprise here and to disclose separately or the combination of claimed technical characterictic, comprise significantly other combination of these features.These distortion and/or combination all fall in the related technical field of the utility model, and fall into the protection domain of the utility model claim.It should be noted that by convention, in claim, use discrete component to be intended to comprise one or more such elements.In addition, any reference marker in claims should be configured to limit scope of the present utility model.
