Summary of the invention
The purpose of this utility model is at the above-mentioned deficiency of existing in prior technology, and a kind of lamp pearl rapid heat dissipation, illumination is even and structure is light and handy LED energy-conserving road lamp are provided.
The utility model is to realize above-mentioned purpose by the following technical solutions: this outward radiation LED energy-conserving road lamp, be on the aluminium backing of its shell, aluminium base circuit board to be arranged by the heat conductive silica gel close installation, some LED lamp pearls are connected into a module and are welded on the circuit board, the luminous intensity distribution reflection shield of tool light fractal transform and polarisation function is installed on the circuit board, end at aluminium backing is equipped with a constant-current supply, and constant-current supply is connected with LED lamp pearl module on the circuit board; One end of aluminium backing is equipped with end cap, and the other end is equipped with holder, and transparent flat safety glass is then adopted at the top; Aluminium backing, end cap, holder and plane safety glass constitute a confined space; Be processed with a plurality of radiating fins at the back side of aluminium backing.
More specifically say, end cap and holder are aluminium die-casting spare, aluminium backing is for stretching high-purity wrought aluminium, LED lamp pearl is adopted the hump LED lamp pearl of 90Lm/W, per 20 lamp pearls are connected into a module, be welded with 3 modules on the circuit board, the input voltage of constant-current supply is 18-30V, and average anode current is 320mA.
The two ends, the left and right sides, top of described end cap, holder and its underpart are connected by long bolt and base and safety glass end face, all adopt the rubber seal crush seal between end cap, holder, base, the safety glass end face; The centre of holder is a columnar fixedly hole clipping, and the hole clipping hole wall is provided with screw, is provided with electric hole in the middle of the hole clipping; Be provided with drainage groove in the heat dissipation channel that adjacent radiating fin constituted, end cap and holder are provided with osculum.
The utlity model has following beneficial effect: the radiating effect of (1) LED lamp pearl chip increases substantially, and has reduced the light decay speed of LED, has improved luminous efficiency, has strengthened the reliability of LED light fixture.(2) solved the illuminance uniformity problem of LED light fixture, every illumination data is all above in the market mill run.(3) base has adopted the aluminium that can stretch, and so just can adjust outer cover length according to different power demands, and mould can reuse, and whole fitting structure is more reasonable, and weight is more light and handy, outward appearance fashion also more attractive in appearance.
