Abstract

The invention discloses an LED (light emitting diode) illuminating lamp. The LED illuminating lamp comprises a housing body and a lamp cover arranged below the housing body, wherein fin-type heat radiators are arranged on the inner sides of the housing body and the lamp cover; aluminum base plates are fixed beneath the heat radiators; multiple LED lamp beads are arranged beneath the aluminum base plates; lower heat radiating holes are distributed on the periphery at the lower part of the housing body; upper heat radiating holes are arranged at the upper part of the housing body; middle heat radiating holes are arranged between the upper heat radiating holes and the lower heat radiating holes on the housing body; and the central lines of the heat radiating holes are all parallel to the base plates. According to the LED illuminating lamp, the middle heat radiating holes are both connecting and fixing holes and wire inlet holes when the lamp is horizontally connected. The upper surfaces of the lower heat radiating holes and the aluminum base plates are on the same horizontal plane, so that the water draining effect can be achieved. In addition, the middle heat radiating holes are also wire inlet holes when the lamp is vertically connected. The distributed upper, middle and lower heat radiating holes facilitate circulation of air in an inner cavity of the housing body, and have better heat radiating effects, so that the service life of the lamp is prolonged.

Description

The LED lighting

Technical field

The present invention relates to a kind of light fixture, particularly a kind of LED lighting.

Background technology

Existing LED lighting lamp structure comprises housing and the lampshade that covers on housing below, at housing and lampshade inboard gilled radiator is arranged, and below radiator, is fixed with aluminium base, is arranged with a plurality of LED lamp pearls below the aluminium base.Wherein radiator is fin type radiator, and fin type radiator has two kinds of application structure modes basically.1: the bareing heat radiation; Advantage is the initial stage good heat dissipation; Shortcoming is easy laying dust, and the foreign material that fall have a strong impact on heat radiation, influences light fixture and uses.2: the radiator that outer cover is arranged.Advantage is to prevent that dust, foreign material from falling the radiating fin surface; Shortcoming is to hinder cross-ventilation influence heat radiation.What have directly offers open-work on housing, because the position in hole and towards unreasonable has influenced dustproof effect again, also influenced heat radiation simultaneously.

Summary of the invention

The purpose of this invention is to provide a kind of simple in structure, can prevent dust, air circulation is strong, the LED lighting of good heat dissipation effect, overcomes the deficiency of prior art.

LED lighting of the present invention comprises housing and the lampshade that covers on the housing below, at housing and lampshade inboard gilled radiator is arranged; Below radiator, be fixed with aluminium base; Be arranged with a plurality of LED lamp pearls below the aluminium base, following louvre arranged, be provided with louvre on the top of housing in the lower part of frame circumferential distribution; Between last louvre and following louvre, be provided with middle louvre on the housing, the center line of described each louvre all is parallel to substrate.

LED lighting of the present invention, middle louvre are connection fixing hole and the entrance hole when laterally connecting light fixture simultaneously.Following louvre and aluminium base upper surface are in same horizontal plane, so can take into account drainage, also are the entrance hole when vertically connecting light fixture in addition.The circulation of housing inner chamber air is convenient in three holes, upper, middle and lower that distribute, and has better radiating effect, has improved the service life of light fixture.

Description of drawings

Fig. 1 is the structural representation of the specific embodiment of the invention.

The specific embodiment

As shown in Figure 1: 1 is housing, and 5 is lampshade.In housing 1 and lampshade 5 inboards gilled radiator 2 is arranged, below radiator 2, be fixed with aluminium base 3, be arranged with a plurality of LED lamp pearls 4 below the aluminium base 3.Lower periphery at housing 1 is distributed with louvre 7 down, evenly is provided with louvre 8 in the upper periphery of housing 1, and louvre 6 between last louvre 8 and following louvre 7, being distributed with on the housing 1 forms the upper, middle and lower-ranking louvre.The center line of each louvre all is parallel to substrate 3, i.e. vertical equity setting.The height and position of following louvre 7 just is in same horizontal plane with aluminium base 3 upper surfaces.

During installation, middle louvre 6 is connection fixing hole and the entrance hole when laterally connecting light fixture simultaneously.Following louvre 7 is in same horizontal plane with aluminium base 3 upper surfaces, so can take into account drainage, also is the entrance hole when vertically connecting light fixture in addition.The circulation of housing 1 inner chamber air is convenient in three holes, upper, middle and lower that distribute, and has better radiating effect, has improved the service life of light fixture.Utilize the installation end 9 that is connected with housing 1 that this LED lighting is lifted on and form the hanging light fixture on the bracing frame, also can place the below to be connected installation end 9 and form and go up the light fixture that supports with bracing frame.
