Abstract
The utility model relates to an LED (light-emitting diode) street lamp, which comprises a lamp body with a cavity. A lamp board is arranged in the lamp body. The lamp board is provided with at least two groups of LED lamp sets which are connected in parallel and are respectively and electrically connected with the outside. Each LED lamp set is at least provided with two LED luminous bodies which are connected in series. A shade body capable of containing the lamp board is arranged below the lamp body. The shade body is transparent. The outer edge of the lamp board is provided with an installing base. The LED street lamp is also provided with a current limiting resistance and a control circuit module which are electrically connected with the LED lamp sets. Due to the adoption of the LED street lamp, the workload of an LED is effectively reduced, the heat productivity of the LED is greatly reduced, and the service life of the LED is greatly prolonged.
Description
Technical field
The utility model relates to a kind of lighting apparatus, specifically, is a kind of LED street lamp.
Background technology
Traditional street lamp generally is made up of the cover body and the bulb of lamp stand, metal lamp housing, transparent material system, there is cavity in lamp housing and the cover body, bulb is arranged in the cavity, in general, bulb is based on high-pressure mercury lamp, but big its consequence brought of high-pressure mercury lamp power is that caloric value is also bigger, and wastes energy.In order to address this problem, many now employing LED luminescent materials specifically, are to adopt a plurality of LED illuminators to be arranged in the lamp group as working flare as working flare, in order to guarantee lighting quality, generally select the high-power LED illuminator for use in actual applications.And the heat that the high-power LED illuminator in use produces is very considerable, if untimely heat radiation, may cause LED to burn, now generally adopt the way active heat removal that on lamp body, installs fan additional, use fan must need perforate, the perforate meeting causes entering of dust, rainy day rainwater also can enter street lamp inside by the hole, thereby can cause the street lamp short circuit.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of simple in structure, the LED street lamp of long service life.
The utility model adopts following technical scheme to be realized:
A kind of LED street lamp, comprise lamp body, lamp plate, described lamp body is provided with cavity, lamp plate is arranged in the cavity of lamp body, the LED lamp group that at least two groups are connected in parallel and are electrically connected with the external world is set on lamp plate, two LED coupled in series illuminators are set in the LED lamp group at least, and described LED street lamp also comprises current-limiting resistance, and described current-limiting resistance is arranged in the lamp body.
Described lamp body bottom is provided with the cover body that can contain lamp plate, and described cover body is a translucent cover.
Described lamp plate outer is provided with the mount pad of fixed lamp body.
Be provided with the control circuit module that is electrically connected with LED lamp group in the described lamp body.
The utility model is provided with current-limiting resistance in lamp body, thereby makes the magnitude of current of LED lamp group be reduced to rated value, has reduced the heat that LED produces under the situation of losing brightness hardly, has also saved the energy.
Description of drawings
Fig. 1 is the utility model structural representation.
Wherein: 1-lamp body, 2-lamp plate, 3-LED illuminator, 4-cover body, 5-mount pad.
The specific embodiment
Below in conjunction with Figure of description the utility model is described in further detail:
The utility model relates to a kind of LED street lamp, and it comprises a lamp body 1, specifically, described lamp body 1 is a metal-back, and the middle part of lamp body 1 raises up, and just forms a cavity at lamp body 1 downside, lamp plate 2 is set in the cavity of lamp body 1, LED lamp group is set on the lamp plate 2.In the utility model, described LED lamp group is provided with two groups at least, for being connected in parallel, supplies with illuminating electric power for LED lamp group thereby the junction in parallel of described LED lamp group is connected with power supply circuits in the lamp stand between the LED lamp group.Two great power LED illuminators 3 are set in each lamp group at least, between the LED illuminator 3 for being connected in series.1 time cover body 4 is installed at lamp body, by cover body 4 lamp plate 2 is contained wherein, cover body 4 is a translucent cover, at the place, outer of lamp plate 2 mount pad 5 is set, and by mount pad 5 lamp plate 2 is fixed with lamp body 1 to combine, and its fixed form can be screw thread, also can be gluing.
In the utility model, described LED street lamp also comprises current-limiting resistance, described current-limiting resistance is arranged on the lamp plate, after current-limiting resistance is set, the electric current of LED illuminator 3 of flowing through just is lowered to below the rated value, though the brightness of LED influences to some extent, the live load of LED effectively reduces, caloric value significantly reduces, and strengthen service life greatly.Also be provided with the control circuit module in described LED street lamp, the control circuit module is arranged between power supply circuits and the LED lamp group, and the purpose that control module is set is the electric current that enters in the LED illuminator 3 is carried out rectification, thereby improves current stability.
