Abstract

The utility model provides a dodging rotary LED floodlight with protective pendant chains and grooves, which mainly solves the problems that the power supply of the existing LED floodlight is poor in heat radiation and cannot work in a high-temperature and high-humidity environment, and the unreasonable structure of the existing power supply. The dodging rotary LED floodlight with protective pendant chains and grooves comprises an LED light source, an LED power supply, a floodlight shell and a floodlight lampshade, wherein the LED power supply comprises a circuit board, a power supply box body and a power supply box cover; the power supply box is U-shaped or L-shaped, and comprises side walls and a bottom plate of the power supply box body; a non-occupation unit is vertically arranged on the circuit board in an independent way, and the working temperature of the non-occupation unit ranges from -4 to 100 DEG C; the power supply box cover is U-shaped, and comprises a top cover of the power supply box cover and side covers symmetrically arranged at both ends of the top cover; and a plurality of bar-shaped holes for heat radiation are formed in the top cover and the side covers.

Description

The even light rotating LED floodlight of band protection chain sling and groove

Technical field

The present invention relates to a kind of even light rotating LED floodlight, belong to the LED lighting field with protection chain sling and groove.

Background technology

Floodlight is a kind of spot light of uniform irradiation to all the winds, floodlight produces be the height diffusion, nondirectional light but not the light beam of clear-cut; Floodlight does not have electrode, is to lean on electromagnetic induction principle to combine with the fluorescence discharge principle and luminous, so there is not the inevitable assembly that limits the life-span in it; The shade that produces is soft and transparent, when being used for the object illumination, the speed that illumination weakens when throwing light on spotlight slowly many, even some illumination weakens very slow floodlight, looks similarly to be a light source that does not produce shade.

The LED illumination promptly is a led lighting, is a kind of semiconductor solid luminescence device.It is to utilize the solid semiconductor chip as luminescent material, in semiconductor, through carrier compound energy of emitting surplus takes place and causes photo emissions, directly sends red, yellow, blue, green, blue or green, orange, purple, white light.The LED illuminating product utilizes LED as the produced ligthing paraphernalia of light source exactly.

The vacant unit of existing LED power supply is generally positioned on the wiring board, and this set-up mode is unfavorable for heat radiation, is not suitable for the operate as normal of hot and humid environment.

The setting of existing power supply lid structure is comparatively unreasonable, is unfavorable for heat radiation, also possibly cause foreign material to fall in the power supply, thereby cause the generation of problems such as power supply short circuit.

Summary of the invention

The present invention provides a kind of even light rotating LED floodlight with protection chain sling and groove, has mainly solved the power supply heat sinking poor performance of existing LED floodlight, works in the hot and humid environment again; The problem of existing power supply unreasonable structure.

Concrete technical solution of the present invention is following:

A kind of even light rotating LED floodlight with protection chain sling and groove comprises led light source, LED power supply, floodlight housing and floodlight lampshade, and this floodlight lampshade is arranged at the led light source outside and is connected with floodlight housing light source side; The floodlight dorsal part is provided with fixed connection apparatus, and this fixed connection apparatus comprises firm banking and installing rack, and firm banking is fixedly connected with the floodlight dorsal part; And be provided with the rotation draw-in groove; Installing rack one end is connected with firm banking through the tightening device, and the other end is connected with mounting points, and the tightening device moves in draw-in groove; This floodlight dorsal part also is provided with at least two root guard chain slings; Also comprise speculum and reflector, speculum and reflector are located in the floodlight lampshade, are fixedly connected with the light source side of floodlight housing; Reflector is arranged at reflecting surface one side of speculum and overlaps with the reflector central point; Led light source is arranged on the central point of reflecting surface and reflector; This floodlight housing dorsal part is provided with heat abstractor; The centre of heat abstractor is provided with groove, and the width of groove is 1/3 ~ 1/4 of a fin width, and the degree of depth of groove is 1/2 ~ 9/10 of a fin maximum height; This LED power supply; Comprise wiring board, power supply box body and power supply lid, this wiring board is fixedly set in the power supply box body, and this power supply box body is " U " type or " L " type; Comprise power pack body sidewall and power supply box plate, wiring board is fixedly set on the power supply box plate; Wiring board is provided with vacant unit, and vacant unit independently is vertically installed on the wiring board, and the operating temperature of vacant unit is-40 ℃ ~ 100 ℃; This power supply lid is the U type, comprises that the power pack caping covers and be symmetricly set in the limit lid at top cover two ends, and this top cover and limit cover and be provided with a plurality of bar holes that are used to dispel the heat, and the limit covers and also is provided with the slotting formula slotted eye that is used for extracting power supply cord; The width of this bar hole is less than 3mm; This bar hole gross area account for power pack caping capping long-pending more than 60%.

The invention has the advantages that:

1, the even light rotating LED floodlight power supply of this band protection chain sling and groove is taked mounting means is in the circuit board erect in vacant unit; Be provided with like this and be prone to heat radiation; Can carry out independent replacing to vacant unit; Be applicable to hot and humid environment, can be at-40 ℃ ~ 100 ℃, operate as normal in 90% humidity environment; When humidity in the power supply was big, dew can flow down along the wiring board of erectting; Simultaneously, erect setting and can form the air channel, be beneficial to airflow and take away heat, further improved radiating effect.

2, the power supply lid dutycycle of the even light rotating LED floodlight of this band protection chain sling and groove is provided with rationally, and intensity is high, is beneficial to processing, and cost is low.
