Description

A kind of high-power LED street lamp

Technical field

The utility model relates to a kind of high-power LED street lamp that street lamp, particularly good heat dissipation effect, energy-conserving and environment-protective are used in illumination.

Background technology

Traditional street lamp adopts osram lamp or high-pressure mercury lamp more, and its shortcoming is that brightness is low, energy consumption is high, service life is short and is big for environment pollution; Efficient at present, energy-conservation, the life-span is grown and the light emitting diode (LED) of environmental protection is used to address these problems, but existing low-power LED luminosity is little, can only be applied to the decoration field, also have by increasing LED quantity or adopting great power LED to improve the luminosity of light fixture, but adopt intensive LED matrix lighting or great power LED, all need to solve the heat radiation of LED, otherwise heat can't in time distribute, directly quicken the LED light decay, thereby make to get a desired effect the service life of light fixture; And in order to reach the effect of light distribution preferably, often need LED is made the whole lamp shape that can reach light distribution effect, be installed in the housing of light fixture the corresponding manufacturing cost that increases light fixture again; For solving heat dissipation problem, what have increases cooling rib arrangement on housing, or on housing, offer louvre, the shell structure more complicated of this light fixture, die sinking expense height, and the light fixture parts are too much, and production and assembly technology is complicated, the production cost height is unfavorable for applying of energy-efficient high-power LED street lamp.

The utility model content

For addressing the above problem, the utility model is intended to propose good heat dissipation effect, the quick and lower a kind of high-power LED street lamp of production cost simple in structure, easy to assembly.

The technical scheme in the invention for solving the above technical problem is: a kind of high-power LED street lamp, contain housing, bright dipping face shield and circuit board, it is characterized in that: the inner chamber integrated inverted ladder type that is of housing, be provided with three or more LED light emitting module on the installed surface in the housing inner chamber, housing inner chamber one end is provided with containing cavity, circuit board is fixed in the containing cavity, and the LED light emitting module is connected with circuit board by lead, and circuit board is connected with circumscripted power line; The shell nozzle outer is provided with integrated with it along groove, the bright dipping face shield with plug together along groove.

LED light emitting module of the present utility model is that square is tabular, which is provided with the LED light emitting diode of some series, parallel or series-parallel connection; The bright dipping face shield is transparent safety glass; Housing is cold stamping shaped by planar metal plate, and its material can adopt the good conductor (as aluminium or Bi-metal Steel Aluminum etc.) of heat; Installed surface is bottom surface and two inclined-planes of housing inner chamber, and the angle on bottom surface and inclined-plane is the obtuse angle, according to the photometric distribution requirement, can be designed to arbitrarily angled to reach needed photometric distribution effect; The shell nozzle outer is a U-shaped, is to be U-shaped along groove promptly, and the bright dipping face shield can directly and plug together fixing along groove.

The beneficial effects of the utility model are: the housing inner chamber is an inverted ladder type, and installed surface within it is provided with the LED light emitting module, and the angle of installed surface can be adjusted according to actual needs, has solved conventional road lamp light-emitting area deficiency, energy consumption height and the low problem of luminosity; Housing directly is as radiator, prolongs the service life of this novel street lamp; Originally novel simultaneously is simple in structure, and assembling and easy to maintenance quick greatly reduces production cost and maintenance cost, helps replacing existing traditional street lamp, helps the sustainable development of conservation-minded society.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is further specified.

As Fig. 1, Fig. 3, Fig. 4 and a kind of high-power LED street lamp shown in Figure 5, housing of the present utility model 1 is cold stamping shaped by planar metal plate, can be directly as this novel radiator, the housing 1 inner chamber integrated inverted ladder type that is, installed surface 5 is bottom surface and two inclined-planes of housing 1 inner chamber, the angle on bottom surface and inclined-plane is the obtuse angle, can adjust this obtuse angle angle according to the actual needs of photometric distribution, and when housing 1 moulding, realize fixed angle, housing 1 inner chamber installed surface 5 is provided with three LED light emitting modules 6, LED light emitting module 6 is that square is tabular, which is provided with some series connection, the LED light emitting diode 7 of parallel connection or series-parallel connection, the heat that high-power LED light emitting module 6 is produced can directly dispel the heat by this new hull 1, avoid the LED light decay to speed up, its life-span is prolonged, housing 1 inner chamber one end is provided with containing cavity 8, circuit board 3 is fixed in the containing cavity 8, LED light emitting module 6 is connected with circuit board 3 by lead, circuit board 3 is connected with circumscripted power line 4, realize energy-conservation, luminous intensity and shadow surface increase, and the life-span is long; As shown in Figure 2, housing 1 opening outer 9 is provided with integrated with it along groove 10, and housing 1 opening outer 9 is a U-shaped, and bright dipping face shield 2 is transparent safety glass, bright dipping face shield 2 with plug together along groove 10.Construct the bright dipping face shield 2 of peaceful slab glass system by the inner chamber inverted ladder type of this new hull 1, solved conventional road lamp and need make LED lamp with photometric distribution, be installed in the light fixture, the bright dipping face shield 2 that solves the manufacturing special optical is to realize light intensity and photometric distribution area again.With this novel being installed on the street lamp electric pole, start power supply, then circuit board 3 driving LED light emitting modules 6 work, the inner chamber of housing 1 inverted ladder type makes its photoirradiated surface increase, high-brightness LED light emitting diode 7 makes that this novel brightness is higher, energy consumption is lower, and because this novel metal housing 1 is the good conductor of heat, help the heat that great power LED light emitting module 6 is produced is in time passed out inner chamber, be different from traditional high-power LED street lamp and need add a large amount of cooling rib arrangements, reduce production costs greatly, help the illumination of this new substituted conventional road lamp, build the energy-saving well-off society of sustainable development.
