Abstract
The utility model provides a rotary type radiating light emitting diode (LED) flood light with a groove. The light mainly solves the problem that the radiating performance of an existing LED flood light power supply is poor and an existing LED flood light cannot work under the condition of high temperature and humidity. The light comprises an LED light source, an LED power supply, a flood light casing and a flood light cover, wherein the LED power supply comprises a circuit board, a power supply case and a power supply case cover, the power supply case is in a U shape or an L shape and comprises a power supply case side wall and a power supply case bottom plate, the circuit plate is fixedly arranged on the power supply case bottom plate, a vacant unit is arranged on the circuit board independently and vertically and the working temperature of the vacuum unit is in a range from -40 DEG C to 100 DEG C. The vacuum unit is installed on the circuit board vertically, the vacuum unit is replaced independently and is suitable to high temperature and humidity environment, an air channel is formed when the vacuum unit is arranged vertically, the air flow is ventilated, heat is brought away, and the radiating effect is improved further.
Description
Technical field
The present invention relates to a kind of rotary cooling LED floodlight, belong to the LED lighting field with 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.
Summary of the invention
The present invention provides a kind of rotary cooling LED floodlight with groove, has mainly solved existing LED floodlight power supply heat sinking poor performance, works in the hot and humid environment again.
Concrete technical solution of the present invention is following:
A kind of rotary cooling LED floodlight with groove comprises led light source, LED power supply, floodlight housing and floodlight lampshade, and said 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 said 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; Said floodlight housing dorsal part is provided with heat abstractor; Said heat abstractor is made up of equally distributed fin, comprises subzero temperature radiating part and streamline radiating part, and described subzero temperature radiating part is arranged on the subzero temperature radiated rib group on the floodlight housing short transverse; The streamline radiating part is arranged on the streamline radiated rib group on the floodlight housing width; The centre of said 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; Said LED power supply comprises wiring board, power supply box body and power supply lid; Said wiring board is fixedly set in the power supply box body; Said 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 set on the power supply box plate; Said 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 ℃.
The invention has the advantages that:
The present invention takes mounting means is in the circuit board erect in vacant unit, is provided with like this to be prone to heat radiation, can carry out independent replacing to vacant unit, is applicable to hot and humid environment, can be at-40 ℃ ~ 100 ℃, and 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.
