The specific embodiment
With the following Examples the application is further described.
A kind of luminous specific embodiment of removing power supply LED street lamp uniformly of the application, as shown in Figures 1 to 4, comprise: cooling base 1, the front of described cooling base 1 is provided with at least two separate module districts 11, between adjacent module district 11, be provided with spacer region 12, described spacer region 12 areas are less than module district 11, each module district 11 is provided with one group of illuminating module, and every group of illuminating module top is provided with the lens board 5 being fixedly connected with cooling base 1, described illuminating module comprises the circuit board 2 being fixed in module district 11, on described circuit board 2, be provided with at least 3 and be placed with LED lamp pearl 3 Bu Deng districts, between adjacent Bu Deng district, be provided with the element region 24 that is fixed with electronic component 4, described element region 24 areas are less than described Bu Deng district, described LED lamp pearl 3 and electronic component 4 form the linear constant-current driving LED circuit of segmented, described lens board 5 covers at described circuit board 2 tops, described lens board 5 comprises plate body, be arranged at lens 51 and the accommodating protruding chamber 52 of plate body, lens 51 couplings are arranged at a LED chip top, accommodating protruding chamber 52 correspondences are arranged at element region 24 tops.
This street lamp adopts many modularity designs, adopt the small-sized LED illuminating module of many groups to form a fairly large luminescent system, because the components and parts that every group of small-sized LED illuminating module is related are fewer, therefore in a module, be more prone to make LED lamp pearl 3 to arrange more even, after only need to having welded each small-sized LED illuminating module while producing, be assembled into again together simultaneously, effectively reduce the complexity welding difficulty of circuit, improved the stability of product; Further, in order to make each illuminating module all can be luminous uniformly, the circuit board of each module 2 is divided into a plurality of Bu Deng district, gap between Bu Deng district arranges element region 24 to place electronic component 4, the element region 24 less by a plurality of areas disperses electronic component 4, avoids electronic component 4 to concentrate occupying whole piece region causing lamp pearl skewness; Further; for each illuminating module is equipped with a lens board 5; lens board 5 is adopted as each LED lamp pearl 3 and is equipped with lens 51; improve the lighting angle of lamp pearl; adopt simultaneously and avoid the light of lamp pearl to be irradiated on electronic component 4 being absorbed or reflect by electronic component 4 causing light maldistribution; accommodating protruding chamber 52 can provide accommodating chamber groove to electronic component 4 simultaneously, and electronic component 4 is protected.
The outer surface in described accommodating protruding chamber 52 is globoidal structure and drops on outside the light emitting region of described LED lamp pearl 3.Because LED lamp pearl 3 is all to have certain light emitting anger when luminous, this light emitting anger must be less than 180 °, so the position in the good accommodating protruding chamber 52 of major control and height, can make accommodating protruding chamber 52 drop on outside the light emitting region of LED lamp pearl 3, and make outer surface that accommodating protruding chamber 52 can be effectively avoided in accommodating protruding chamber 52 outside dropping on LED lamp pearl 3 light emitting regions produce light, disturb, thereby guaranteed that whole lamp sends out uniformity of light.In addition the globoidal structure in accommodating protruding chamber 52 can guarantee to have larger accommodation space with holding electronic element 4 when accommodating protruding chamber 52 is outside dropping on LED lamp pearl 3 light emitting regions.
The front of described cooling base 1 is provided with the waterproof groove 15 that ring module district 11 arranges, and in described waterproof groove 15, is filled with marine glue, and described illuminating module is arranged at waterproof groove 15 inner sides, and described housing covers and be connected to waterproof groove 15.Illuminating module can be effectively isolated from the outside, avoid lamp pearl and electronic device to break down because of reasons such as water inlets.
The back side of described cooling base 1 is provided with the radiating fin 13 being parallel to each other, the boundary line of described module district 11 and described spacer region 12 and the vertical setting of described radiating fin 13.The back side of described cooling base 1 is provided with and the vertically disposed convection channel 14 of described radiating fin 13, and described convection channel 14 is arranged at the back side of the spacer region 12 of described cooling base 1.Set up convection channel 14 and can strengthen the convection effects of radiating fin 13, effectively improve the radiating effect of light fixture integral body, simultaneously, convection channel 14 is arranged on the back side of spacer region 12, module district 11 can not cause due to the setting of convection channel 14 radiating fin 13 areas of each module district 11 correspondences to reduce, and owing to there is no LED lamp pearl 3 or electronic component 4 on spacer region 12, therefore radiating requirements is few, and radiating fin 13 corresponding to this position being changed into convection channel 14 can be to causing this region not enough problem of dispelling the heat.
The back side of described cooling base 1 is provided with Connection Block 16, on described Connection Block 16, is connected with fixture 6, is connected with a joggle to realize to select angle adjustable between described Connection Block 16 and fixture 6.Connection Block 16 meshes by gear structure with holder, therefore can be rotationally connected seat 16 makes mutually to rotate between gear, and the tooth number class rotating by control is controlled the angle value rotating, and for the ease of adjusting angle value, scale can also be set on gear.
Described electronic component 4 comprises the syllogic linear constant-current driving LED circuit of the linear constant-current driving LED circuit of segmented for realizing based on IML8683 chip.IML8683 chip is a constant current chip, based on this chip, has the linear constant-current driving LED circuit arrangement of ripe segmented, repeats no more herein.
Set LED lamp pearl 3 quantity in each Bu Deng district are 2 to 12, and the lamp pearl series connection in same Bu Deng district arranges.With this, avoid lamp pearl too to concentrate and cause poor heat radiation and non-uniform light.
Described circuit board 2 is square plate, and described Bu Deng district and element region 24 are square region.With respect to border circular areas, square region is convenient to carry out the regular design of arranging between regional, avoids due to the luminance nonuniformity that exists the region of irregularity to cause.
Described circuit board 2 comprises the Bu Deng of left wing district 21, middle Bu Deng district 22 and right flank Bu Deng district 23, the described Bu Deng of left wing district 21, middle Bu Deng district 22 and right flank Bu Deng district 23 are arranged in order setting along circuit board 2 longitudinal directions, and described middle Bu Deng district 22 areas are greater than the area in the Bu Deng of left wing district 21 and the area in right flank Bu Deng district 23.The middle Bu Deng of employing district 22 is greater than the design in both wings Bu Deng district, the luminous efficiency of reinforcement mid portion, and whole like this light irradiation light center is out slightly strong, a little less than omit on all edges, more realistic lighting demand.
Finally should be noted that; above embodiment is only in order to illustrate the application's technical scheme; but not restriction to the application's protection domain; although the application has been done to explain with reference to preferred embodiment; those of ordinary skill in the art is to be understood that; can modify or be equal to replacement the application's technical scheme, and not depart from essence and the scope of present techniques scheme.
