Abstract

The utility model relates to a technical solution of an LED lamp comprising an upper end cap, a lamp shell, a circuit board, an aluminum substrate, a reflection board, a lamp cap as well as a lower end cap; the lamp shell is arranged between the upper end cap and the lower end cap; the inner end face of the lamp shell is connected with the aluminum substrate, the reflection board, the circuit board as well as the lamp cap; the technical solution is further innovatively provided with cooling fins and a drainage groove on the outer end face of the lamp shell; the introduction of a drainage groove in the LED lamp provided hereby greatly helps effectively drain the raindrops or thawed water thereon; in addition, the parallel straight cooling fins equipped on the lamp cover a greater cooling area, and at the meanwhile, the extra heat dissipation and drainage holes arranged on the upper end cap, on the lower end cap, as well as on the side board greatly improve the heat dissipation capability of the lamp. With a 30 degree arc-shaped design, the reflection board not only covers a greater illuminating area, but it also increases the uniformity of the light radiated on the ground.

Description

A kind of LED lamp

Technical field

The utility model relates to a kind of illuminations, relate in particular to a kind of LED lamp that is used for highway lighting.

Background technology

In the existing highway illuminator, seldom have and adopt the LED lamp as the highway lighting lamp.The main cause that this problem occurs is: the cooling system of LED lamp is not too desirable at present, thereby the life-span of having caused the LED street lamp is not very long, also there are some difficulties in mediating of snow-broth after the rainwater of sleety weather and the thawing, and this has all influenced the extensive use of LED street lamp.As seen, the existing in prior technology weak point be exactly the effect of in time mediating of radiating effect and sleet water be not too desirable.

Summary of the invention

The purpose of this utility model is exactly at the existing in prior technology deficiency, and a kind of technical scheme is provided, and this programme can solve the cooling system and the sleet water of existing LED lamp and in time mediate relatively poor problem.

This programme is realized by following technical measures: a kind of LED lamp of the present utility model includes upper end cover, lamp housing, wiring board, aluminium base, reflector, lampshade and bottom end cover; Described lamp housing is between upper end cover, bottom end cover, and the lamp housing inner face links to each other with aluminium base, reflector, wiring board and lampshade; Its special feature is: described lamp housing outer face is provided with fin and drainage trough.The concrete characteristics of this programme also have, and described fin is one group of straight plate that is parallel to each other; Described reflector is 30 ° arc; Described drainage trough direction is identical with the direction of fin; Described upper end cover, bottom end cover are connected with gluing lid and following Jiao Gai respectively; Be connected with air outlet valve on the described upper end cover; Described lamp housing is connected with side plate; Be connected with waterproof pad between described lamp housing and the upper end cover, be connected with the marine glue filler strip between lamp housing and the lampshade; Described upper end cover, bottom end cover and side plate all are provided with the heat radiation conduction hole; Described reflector is divided into reflector I and reflector II.

The beneficial effect of this programme can learn according to the narration to such scheme owing in this programme, adopt drainage trough, to the rainwater of sleety weather, melt snow-broth in time mediated bigger change; Adopt one group of parallel straight plate heat sink, increased area of dissipation, set up the heat radiation conduction hole of upper end cover, bottom end cover and side plate simultaneously, thereby the radiating effect of LED lamp is had clear improvement; Described reflector adopts 30 ° arc design, Zhao She angle bigger (horizontal 145 °, vertical 60 °) not only, and impinge upon the ground uniformity corresponding raising (bringing up to 0.4 by original 0.3) is also arranged.Owing to this shows that the utility model compared with prior art has substantive distinguishing features and progress, the beneficial effect of its enforcement also is conspicuous.

Description of drawings

Fig. 1 is the structural representation of the utility model specific embodiment.

Fig. 2 is the stereogram of the utility model specific embodiment.

Among the figure, 1 is the gluing lid, and 2 is air outlet valve, and 3 is upper end cover, 4 is waterproof pad, and 5 is side plate, and 6 is lamp housing, and 7 is constant-current supply, 8 are following Jiao Gai, and 9 is the waterproof terminal, and 10 is bottom end cover, 11 is aluminium base, and 12 is wiring board, and 13 is waterproof adhesive tape, 14 is lampshade, and 15 is reflector I, and 16 is reflector II, 17 is drainage trough, and 18 is fin, and 19 are the heat radiation conduction hole.

The specific embodiment

For clearly demonstrating the technical characterstic of this programme,, and, this programme is set forth in conjunction with its accompanying drawing below by a specific embodiment.

By accompanying drawing 1-2 to find out that LED lamp of the present utility model includes upper end cover 3, lamp housing 6, wiring board 12, aluminium base 11, reflector I 15, reflector II 16, lampshade 14 and bottom end cover 10; Described lamp housing 6 is between upper end cover 3, bottom end cover 10, and lamp housing 6 inner faces link to each other with aluminium base 11, reflector I 15, reflector II 16, wiring board 12 and lampshade 14; Its special feature is: described lamp housing 6 outer faces are provided with fin 18 and drainage trough 17.

LED lamp of the present utility model is connected on the constant-current supply 7 by waterproof terminal 9, add that LED lamp upper end cover 3, bottom end cover 10 are connected with gluing lid 1 respectively and play glue covers 8, be connected with waterproof pad 4 between lamp housing 6 and the upper end cover 3, be connected with marine glue filler strip 13 between lamp housing 6 and the lampshade 14.Such hermetically-sealed construction prevents that the effect that the snow-broth of rainwater and thawing enters in the LED lamp is very obvious.

Even there is the snow-broth of rainwater and thawing to enter LED lamp inside, all is provided with heat radiation conduction hole 19 and also can rapidly water be derived the LED lamp because lamp housing 6 outer faces of LED lamp of the present utility model are provided with drainage trough 17 and upper end cover 3, bottom end cover 10 and side plate 5.

Lamp housing 6 outer faces of LED lamp of the present utility model are provided with fin 18; Upper end cover 3, bottom end cover 10 and side plate 5 all are provided with on heat radiation conduction hole 19 and the upper end cover 3 and are connected with air outlet valve 2.Such structure radiating effect has had raising significantly.
