Description

Modular LED lamp with radiator structure

Technical field

The utility model relates to a kind of LED light fixture, specifically is meant a kind of Modular LED lamp with radiator structure.

Background technology

LED light fixture development fast at home and abroad at present, LED light fixture market potential as functional illumination is huge, and existing market has begun to start, domestic also just the beginning promoted, existing LED light fixture comprises integrated LED mounting base and radiating fin, mounting base is a platy structure, there is following problem in this LED light fixture: 1) volume is big, Heavy Weight, die cost is higher: most of producers are in order to allow the heat radiation of high-power LED light fixture reach certain requirement, do not increase the area of radiator and achieve the goal with regard to stinting, this has just caused the lamp casing partial volume bigger than normal, weight lays particular stress on, and has finally also caused die cost higher; 2) Installation and Debugging and maintenance are not strong than trouble, adaptability: because bigger volume and heavier weight, just there is certain risk during installation, installation difficulty is higher, and the led light source of most of producer is concentrated on a wiring board or the aluminium base, just need integral replacing just in case go wrong, can only beam back producer and repair.Be exactly that adaptability is not strong in addition, the road conditions of domestic some road are not necessarily pressed index formation, and the condition of installation is also different, and present most of light fixtures particularly street lamp are installed on some road and will be had the not enough problem of illumination, have potential safety hazard; 3) luminous intensity distribution is unreasonable, the light effective rate of utilization is low: most of LED light fixtures particularly LED street lamp concentrate on led light source on the one monoblock aluminium base, because there is certain angle in the bright dipping of LED, to prepare it, meet national standard, increase lens with regard to needs and carry out secondary light-distribution, to having relatively high expectations of lens, and there is certain light loss; 4) most of producer does not consider the self-cleaning function of light fixture radiating shell, after accumulating over a long period, can accumulate suitable dust on the radiating shell, finally influences the radiating effect of LED, causes lamp life to reduce; 5) most of light fixture producer only considered the LED radiator front and back or about cross-ventilation, and do not consider the cross-ventilation up and down of radiator.

Summary of the invention

The utility model is at the problems referred to above that prior art exists, and a kind of good heat dissipation effect is provided, structure is light and can accumulate the Modular LED lamp with radiator structure of dust.

The technical scheme that the utility model adopted is:

A kind of Modular LED lamp with radiator structure, comprise LED mounting base and fixed support, described LED mounting base is combined by the base unit of modular, pedestal comprises at least two foundation seat unit and a plurality of radiating fins of being located on the base unit, and every foundation seat unit is provided with a plurality of LED lamp installing holes.

Described each radiating fin is arranged along base unit longitudinal separation, and is connected with base unit is removable.

Described base unit and fixed support flexibly connect.

Described base unit longitudinal separation is provided with some mounting grooves for the radiating fin insertion, and radiating fin is removable to be installed in the mounting groove.

Mounting base is provided with the angle adjusting mechanism that can adjust the LED mounting base by fixed support and lamp stand location between fixed support and the lamp stand.

Described governor motion comprises and is fixedly connected on retainer plate on the lamp stand, is fixed on the adjusting ring on the support that screw rod passes adjusting ring and retainer plate, and by the nut location, described LED mounting base and lamp stand are elevation angle setting.

The LED mounting base unit that is positioned at LED mounting base both wings have the LED installing hole towards outside inclination certain angle.

Described base unit front end has the bending segment that is upturned.

Described fixed support comprises that main fixed mount vertically is connected with main fixed mount with an end, the other end and each base unit middle part secondary fixed support connected vertically.

The base unit two ends have the bending segment that is upturned, and base unit integral body is curved.

The beneficial effects of the utility model are: 1) pedestal of the present utility model is formed by the modular base unit combination, and volume is little, in light weight, and die cost is low; 2) the utility model is because volume in light weight is little, Installation and Debugging are more convenient, and maintenance is also more convenient, if wherein a light source base unit is downright bad, can only need to change this light source base unit just can, and do not need to change the light source of whole light fixture, do not need whole light fixture to transport company's maintenance back, as long as the dispensing accessory just can keep in repair; 3) can be two also can be more than two to base unit of the present utility model, so just can be comparatively even to the adjusting and the distribution of luminous intensity distribution, make the centre and the both wings of light fixture range of exposures can obtain evenly reasonably irradiation, and can also regulate some special highway sections, luminous intensity distribution is met the requirements.And do not need the scioptics secondary light-distribution, under the situation that guarantees light distribution requirements, reduce the loss of luminous energy.In order better to meet the requirement of road Lighting Design standard, as the words of the street lamp light fixture integral body certain angle that can suitably raise up when mounted, and base unit can be done some bending adjustment; 4) saturating vertically and up and down empty heat dissipation design fin can increase the convection current of air to a great extent, and can prevent dust, and has both increased the radiating effect of light fixture, can guarantee that again light fixture is durable in use.
