Abstract

The utility model provides an LED (Light-Emitting Diode) ceiling lamp which is mainly used for solving the problems that the existing ceiling lamp has poor heat radiation property of an LED power source and cannot work in a high-temperature and high-humidity environment, and the prior art has an unreasonable structure. The LED ceiling lamp comprises an LED light source, an LED power source, a ceiling lamp shell and a ceiling lamp cover; the LED power source comprises a circuit board, a power source box body and a power source box cover; and a non-occupation unit is independently and vertically arranged on the circuit board. According to the LED ceiling lamp provided by the utility model, the non-occupation unit is vertically arranged on the circuit board, so that the non-occupation unit can be independently replaced; an air duct can be formed due to vertical arrangement of the non-occupation unit, so that the heat radiation effect is further improved; and a power source mounting hole comprises a bar-shaped hole and a U-shaped hole, so that the quantity of the mounting manners is increased by the design of the two holes. The LED ceiling lamp is applicable to various different mounting fields.

Description

A kind of LED pendent lamp

Technical field

The present invention relates to a kind of LED pendent lamp, belong to the LED lighting field.

Background technology

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 the LED power supply of existing LED pendent lamp 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 installing hole of existing power supply is provided with single, when in a single day machining accuracy does not meet the demands, possibly cause power supply can't be installed on the mounted piece; Simultaneously, the installing hole of LED pendent lamp power supply is single, causes mounting means single, if construction space is less, thereby instrument possibly can't go deep into causing and can't installing.

Summary of the invention

The present invention provides a kind of LED pendent lamp, has mainly solved the LED power supply heat sinking poor performance of existing pendent lamp, works in the hot and humid environment again.The prior art installing hole is provided with single, causes mounting means single, the problem of bad adaptability.

Technical solution of the present invention is following:

This LED pendent lamp comprises led light source, LED power supply, pendent lamp housing and canopy, and said canopy is arranged at the led light source outside and is connected with pendent lamp housing light source side, and said LED pendent lamp is fixed on the installation position through installing plate, and chain sling is connected with installing plate; Described installing plate is provided with the chain sling installing hole identical with the chain sling number; Installing plate is similar with the shape of pendent lamp housing; Also be provided with on the installing plate and be mounted a jockey that is connected; Said LED pendent lamp also comprises speculum and reflector, and speculum and reflector are located in the canopy, is fixedly connected with the light source side of pendent lamp 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, and said pendent lamp housing dorsal part is provided with heat abstractor, and said heat abstractor is made up 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 the pendent lamp housing short transverse, and the streamline radiating part is arranged on the streamline radiated rib group on the pendent lamp housing width, and the centre of said heat abstractor is provided with groove; 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; The 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; Vacant unit independently is vertically installed on the wiring board, and the operating temperature of vacant unit is-40 ℃～100 ℃; The power supply box plate is provided with at least three group connecting holes that are used for fixing power supply, and each is organized connecting hole and forms by an identical bar hole and U type hole; Be provided with between bar hole and the U type hole and be used to the limited block that prevents that bar hole is communicated with U type hole; Connecting hole is symmetrically arranged with four groups.

The invention has the advantages that:

The power supply of this LED pendent lamp is taked 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, the power supply installing hole comprises bar hole and U type hole, and the design in two kinds of holes has increased multiple mounting means, is applicable to multiple different installation occasion.
