Description
Technical field
The utility model relates to the lighting apparatus field, relates in particular to the street lamp of a kind of LED of use as light source.
Background technology
Transitional street lamps mainly contains 2 kinds on the market, a kind of is that the employing high-pressure mercury lamp is a light source, use this high pressure sodium lamp need mix corresponding inductance rectifier, its defective is that energy consumption is quite high, caloric value is very big, and service life is short, and the inductance rectifier is in use because the variation of electric current and voltage, light source can produce stroboscopic, and the light source stroboscopic can exert an influence to driver's sight line.Another kind is that to adopt LED be light source, and led light source is because multiple advantages such as its efficient, energy-saving and environmental protection have replaced high-pressure mercury lamp gradually.Its structure of led light source in the existing street lamp comprises LED and wiring board, and LED is by lamp wall, chip, epoxy resin and be configured to, and chip is located in the groove of cantilever tip, scribbles fluorescent material on the chip, and lamp wall and cantilever tip are fixed by epoxy resin.Connected mode all is to adopt pins type, and promptly LED inserts in the wiring board fixing by support.The existing defective of the street lamp existence of led light source that adopts is: the heat that led chip produces when 1, working all dispels the heat by support, but because the area of support is little, heat radiation inconvenience, the heat that chip produces can not outwards discharge as soon as possible, make chip overheating damage, thereby influenced the service life of led light source; 2, the epoxy resin in the LED is subjected to ultraviolet interference easily, and after LED worked long hours, it is muddy that resin slowly can become, thereby influences the luminous efficiency of LED when work.
Summary of the invention
Goal of the invention of the present utility model is in order to overcome the existing deficiency that adopts street lamp to exist, and provides that a kind of led chip radiating rate is fast, long service life, street lamp that luminous efficiency is good.
The technical solution of the utility model is: a kind of street lamp, comprise housing, implosion guard and light source, implosion guard is installed in the housing top, light source is located in the housing, described light source is the led light source plate, also be provided with the Switching Power Supply of heat-dissipating aluminium plate and constant current constant voltage in the described housing, heat-dissipating aluminium plate is fixed in the housing, and the led light source plate is fixed on the heat-dissipating aluminium plate; The led light source plate connects the Switching Power Supply of constant current constant voltage by lead.
As preferably, described led light source plate is made of LED, wiring board and aluminium base, and aluminium base is provided with the bowl-type groove, in the bowl-type groove LED is set; Described LED comprises chip and fluorescent material, and chip is fixed on the bowl-type groove bottom, and fluorescent material is located on the chip; Described wiring board is arranged on the aluminium base, and wiring board is connected by gold thread with chip.
As preferably, described housing inner bottom part is installed with the insulation offset plate, and the Switching Power Supply of constant current constant voltage is located on the insulation offset plate.
As preferably, be provided with fixed mount in the described housing, heat-dissipating aluminium plate is fixedly mounted on the fixed mount.
By a kind of street lamp of the technical solution of the utility model design, use the led light source plate, very energy-conservation.Heat-dissipating aluminium plate can be fast distributes the heat of led light source plate, prevents that it from crossing cause thermal damage.The Switching Power Supply of constant current constant voltage provides stable output current same voltage for the led light source plate, when working a stable status is arranged to guarantee it, and LED can not produce stroboscopic.The led light source plate does not re-use the support of traditional LED, increased aluminium base, chip is directly arranged in the bowl-type groove on the aluminium base, and chip can dispel the heat by aluminium base, aluminium base is more accelerated in conjunction with the heat-dissipating aluminium plate radiating rate, the bowl-type groove the irradiating angle that can strengthen LED is set.Do not re-use epoxy resin, working long hours also to influence the luminous efficiency of LED.Switching Power Supply is installed on the insulation offset plate, prevent its contact with inner walls be damaged, situation such as electric leakage.Heat-dissipating aluminium plate is fixedly mounted on the fixed mount, can make heat-dissipating aluminium plate and on the position of led light source plate firm.This street lamp also has long service life, safeguards advantage eaily.
