Abstract
The utility model discloses a high-power LED (Light-Emitting Diode) street lamp, which comprises an upper shell, wherein at least three LED lamps which are connected with each other are embedded into the upper shell; and the lower end of the upper shell is provided with a non-light tight cover through recesses on the periphery. The high-power LED street lamp is characterized in that: the inner cavity of the upper shell is provided with a temperature sensor and a radiating fan which are connected in series; a fixed cover plate is clamped between the upper shell and the non-light tight cover, and is provided with lens holes of which the quantity corresponds to that of LED lamp positions; and a power supply device is arranged in an inner cavity formed by the non-light tight cover and the fixed cover plate, and is connected with the LED lamp and the temperature sensor through leads. The high-power LED street lamp has a good radiating effect; and moreover, the temperature of the street lamp can be controlled effectively, and the service life of the LED street lamp is prolonged.
Description
Technical field
The utility model relates to a kind of LED lamp, specifically is meant high-powered LED lamp.
Background technology
Along with development of semiconductor; LED has become the third generation illuminating lamp source behind lightings such as incandescent lamp, fluorescent lamp as semiconductor light sources, but great power LED must in time be derived the heat that led light source produces during work owing to its characteristic requirements; If the LED lamp does not adopt the cooling modular construction of perfect heat-dissipating; LED power is little still can normally to be used, and when LED power was big, the heat that LED sends can not well distribute; And cause the damage of LED lamp, influence the life-span of LED lamp and people's normal use.
The utility model content
The purpose of the utility model is to overcome weak point of the prior art, and the high-power LED street lamp of a kind of perfect heat-dissipating, reasonable in design is provided.
The purpose of the utility model realizes through following technical scheme:
High-power LED street lamp; Comprise upper shell, upper shell is embedded with at least three LED lamps that are connected, and the lower end of upper shell is fitted with diffuser through the recess of periphery; Clamped securing cover plate between upper shell and the diffuser; This securing cover plate is provided with and LED lamp position and all corresponding lens opening of number, and in order to increase the heat conduction efficiency of lamp body upper end, the inner chamber of upper shell is provided with temperature sensor and the radiator fan that is connected; The inner chamber that diffuser and securing cover plate form is equipped with supply unit, and this supply unit connects described LED lamp and temperature sensor through lead.
When temperature sensor perceives led light source temperature on the securing cover plate when too high, can connect the circuit of radiator fan automatically, make radiator fan work, and reduce electric current supply led light source, can in time reduce the temperature in the light fixture like this.When temperature returns to preset normal value in temperature sensor perceives light fixture, the circuit of automatic disconnection radiator fan then, radiator fan stops operating, and recovers the normal current supply to led light source.
As the further improvement of this programme, for satisfying multiple connecting, the LED lamp be connected to serial or parallel connection.
As another improvement of this programme, upper shell and securing cover plate are processed by the aluminium of good heat conductivity.
The utility model compares that prior art has the following advantages and beneficial effect:
The LED street lamp adopts between upper shell and the diffuser and clamps securing cover plate, and this securing cover plate is shaped on the lens opening with the corresponding number of LED lamp, its reasonable in design; Easy for installation; And shell adopts aluminum material, not only alleviated the weight of street lamp, and radiating effect is better; Mounting temperature sensor and radiator fan in the while LED street lamp; Not only can shift out a large amount of heats that great power LED when work produces rapidly, the timely temperature of led light source in the Based Intelligent Control street lamp helps to reduce the light decay of led light source.So the design is good heat dissipation effect not only, and can effectively control the temperature of street lamp, prolong the service life of LED street lamp.
Description of drawings
Fig. 1 is the overall schematic of the utility model high-power LED street lamp
The specific embodiment
Below in conjunction with embodiment and accompanying drawing the utility model is described in further detail, but the embodiment of the utility model is not limited thereto.
Embodiment
High-power LED street lamp; Comprise upper shell 1; Upper shell 1 is embedded with at least three LED lamps 2 that are connected; Upper shell 1 lower end is fitted with diffuser 3 through the recess of periphery, has clamped securing cover plate 9 between upper shell 1 and the diffuser 3, and this securing cover plate 9 is shaped on the lens opening (not shown) with LED lamp 2 corresponding numbers.For satisfying multiple connecting, LED lamp 2 be connected to serial or parallel connection.Run through fixing through securing member 6 between upper shell 1, securing cover plate 9 and the diffuser 3.
In order to increase the heat conduction efficiency of lamp body upper end, the inner chamber of upper shell 1 is provided with the temperature sensor 10 and radiator fan 4 that is connected.
When temperature sensor 10 perceives led light source temperature in the lamp body when too high, can connect the circuit of radiator fan 4 automatically, make radiator fan 4 work, and reduce electric current supply led light source, can in time reduce the temperature in the light fixture like this.When temperature sensor 10 perceives that temperature returns to preset normal value in the light fixture, the circuit of automatic disconnection radiator fan 4 then, radiator fan 4 stops operating, and recovers the normal current supply to led light source.
Upper shell 1 is processed by the aluminium of perfect heat-dissipating with securing cover plate 9.
Diffuser 3 is equipped with supply unit 5 with the inner chamber that securing cover plate 9 forms, and this supply unit 5 connects described LED lamp 2 and temperature sensor 10 through lead 7.
The foregoing description is the utility model preferred implementation; But the embodiment of the utility model is not restricted to the described embodiments; Other any do not deviate from change, the modification done under spirit and the principle of the utility model, substitutes, combination, simplify; All should be the substitute mode of equivalence, be included within the protection domain of the utility model.
