Abstract
The invention provides an even light rotary heat dissipating light-emitting diode (LED) floodlight with a protective pendant chain. The even light rotary heat dissipating LED floodlight with the protective pendant chain mainly solves the problems that an LED floodlight in the prior art is poor in heat dissipating performance of a power supply and incapable of working under a high-temperature high-dampness environment and power heat conduction performance and intensity are poor in the prior art. The even light rotary heat dissipating LED floodlight with the protective pendant chain comprises an LED light source, an LED power supply, a floodlight shell body and a floodlight cover. The LED light source comprises a circuit board, a power supply box body and a power supply box cover. A vacant unit is independently arranged on the circuit board in a vertical mode. The even light rotary heat dissipating LED floodlight with the protective pendant chain can enable the vacant unit to be changed independently due to the fact that the vacant unit is arranged on the circuit plate in a vertical mode, be applied to a high-temperature high-dampness environment, and the vacant unit can be vertically arranged to form an air duct to benefit circulation of air current to take heat and further improve dissipating effect. The power supply box body is integrated, heat dissipation is even and intensity is high. Due to the fact that the back of the box body is processed, the box body is enabled to be closely attached with an installing component to be installed and benefit heat conduction.
Description
Technical field
The present invention relates to a kind of even smooth rotary heat radiation LED floodlight with pendant chains, belong to the LED lighting field.
Background technology
Floodlight is a kind of spot light of to all the winds uniform irradiation, floodlight produces be the height diffusion, nondirectional light but not the light beam of clear-cut; Floodlight does not have electrode, is to combine with the fluorescence discharge principle and luminous by electromagnetic induction principle, 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 like a light source that does not produce shade.
The LED illumination is namely LED lighting, is a kind of semiconductor solid luminescence device.It is to utilize the solid semiconductor chip as luminescent material, by carrier, compound energy of emitting surplus occurs and cause photo emissions in semiconductor, 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 wiring board, and this set-up mode is unfavorable for heat radiation, is not suitable for the normal operation of hot and humid environment.
The existing power supply box body is generally the split part, cause like this intensity of power supply box body lower, and the each several part heat dispersion is inconsistent, is unfavorable for heat radiation; Simultaneously, does not generally process existing power supply box body bottom, causes power supply bottom and mounted piece to be fitted not tight, is unfavorable for the heat conduction.
Summary of the invention
The invention provides a kind of even smooth rotary heat radiation LED floodlight with pendant chains, mainly solved the power supply heat sinking poor performance of existing LED floodlight, work in hot and humid environment again; The problem that existing power supply heat-conductive characteristic and intensity are relatively poor.
Concrete technical solution of the present invention is as follows:
a kind of even smooth rotary heat radiation LED floodlight with pendant chains, comprise LED light source, the LED power supply, floodlight housing and floodlight lampshade, described floodlight lampshade is connected with floodlight housing light source side outside being arranged at LED light source, the floodlight dorsal part is provided with fixed connection apparatus, described fixed connection apparatus comprises firm banking and installing rack, 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 by locking apparatus, the other end is connected with mounting points, locking apparatus moves in draw-in groove, described 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, be 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, be provided with heat abstractor on described floodlight housing dorsal part, described heat abstractor is comprised of equally distributed fin, comprise subzero temperature radiating part and streamline radiating part, described subzero temperature radiating part is arranged on the subzero temperature radiated rib group on floodlight housing short transverse, and the streamline radiating part is arranged on the streamline radiated rib group on floodlight housing width, described LED power supply comprises wiring board, power supply box body and power supply lid, described wiring board is fixedly installed in the power supply box body, described power supply box body is " U " type or " L " type, comprises power pack body sidewall and power supply box plate, and wiring board is fixedly installed on the power supply box plate, described vacant unit independently is vertically installed on wiring board, and the operating temperature of vacant unit is-40 ℃～100 ℃, described power supply box plate away from circuit board one side be mounted the position and fit fully, the insulating heat-conductive box that power supply box plate and power pack body sidewall are formed in one.
The invention has the advantages that:
1, this power supply with the even smooth rotary heat radiation LED floodlight of pendant chains is taked vacant unit setting mounting means in the circuit board, easy heat radiation is set like this, can carry out independent replacing to vacant unit, be applicable to hot and humid environment, can at-40 ℃～100 ℃, work in 90% humidity environment; When in power supply, humidity was larger, 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, this power supply box body with the even smooth rotary heat radiation LED floodlight of pendant chains is integrated part, and heat radiation is even, and intensity is high; Simultaneously, the box body back is processed, make its with mounted piece between contact closely, be beneficial to the heat conduction.
