Abstract
The utility model discloses an LED ceiling lamp with high radiating efficiency. The LED ceiling lamp comprises a lamp body with an inner cavity, an LED light source assembly arranged at the bottom of the inner cavity of the lamp body, a cover covering an opening of the lamp body and a drive device electrically connected with the LED light source assembly. The bottom face of the lamp body extends downwards to form a plurality of radiating fins in a radial shape, the contact area of the lamp body and external air is greatly increased, and accordingly large-area heat exchange between heat of the lamp body and the external air can be achieved, and heat in the lamp body can be quickly exhausted. Additionally, the inner cavity of the lamp body is provided with a plurality of ventilation holes which are opposite in straight lines and are communicated with the exterior, the ventilation holes are in-out channels for air convection, air convection is facilitated, the air flowing rate is accelerated, the radiating effect is ideal and service life of an LED down lamp is effectively prolonged.
Description
Technical field
The utility model relates to the LED lighting field, the LED Ceiling light that particularly a kind of radiating efficiency is high.
Background technology
LED, owing to having various excellent properties, is widely applied on lighting, and the application of LED Ceiling light is also more and more extensive, and the luminous efficiency of LED Ceiling light is high, brightness strong, energy-conserving and environment-protective.But the heat dissipation problem of LED Ceiling light is the outstanding problem that a needs solves, the heat of LED lamp pearl concentrates in small-sized chip, can make the chip internal temperature more and more higher, it is aging that continuous high temperature not only accelerates light fixture, reduction of service life, when serious, can cause chip to burn, the quality of the radiating effect of LED Ceiling light is directly connected to illumination effect and the life-span of light fixture, a heat radiation difficult problem for the LED Ceiling light, on market, the radiator of LED lamp is multifarious, but most design comparison very complicated and radiating effect is unsatisfactory.
Therefore, how to realize that a kind of radiating efficiency is high, the LED Ceiling light of long service life is technical problem urgently to be resolved hurrily in the industry.
The utility model content
Main purpose of the present utility model is to provide the LED Ceiling light that a kind of radiating efficiency is high, is intended to realize that a kind of radiating efficiency is high, the LED Ceiling light of long service life.
The utility model proposes the LED Ceiling light that a kind of radiating efficiency is high, comprise lamp body with inner chamber, be located at the lamp body intracavity bottom the LED light source assembly, cover at the cover cap of lamp body opening part, also comprise the drive unit be connected with the LED light source electrical component, the lamp body bottom surface is extended the radiating fin of some formation radiation shapes down, and the inner chamber of lamp body is provided with some straight lines relatively and is communicated to outside air vent.
Preferably, the quantity of air vent is no less than 4.
Preferably, also comprise that peace is fixed in the light transmission piece between lamp body and cover cap.
Preferably, the LED light source assembly comprises the circuit board of being close to the lamp body intracavity bottom, the LED lamp pearl that evenly is laid on circuit board and is electrically connected to drive unit.
Preferably, the drive unit peace is fixed in lamp body inside or is arranged at the lamp body outside.
Preferably, also comprise the Elastic buckle of being located at the lamp body marginal position.
Preferably, the lamp body structure that is formed in one.
Circuit board of the present utility model is close to the intracavity bottom of lamp body, and the lamp body structure that is formed in one, the heat that LED lamp pearl is produced can promptly spread all over whole lamp body; The utility model also extends the radiating fin of some formation radiation shapes down in the lamp body bottom surface, greatly increased the contact area with extraneous air, make the heat on lamp body carry out large-area exchange heat with extraneous air, get rid of fast the heat in lamp body; In addition, be provided with some straight lines relatively on the inner chamber of lamp body and be communicated to outside air vent, between air vent, can become cross-ventilated access way, be conducive to cross-ventilation, accelerate air flow rate, the radiating effect ideal, effectively extend service life of LED Down lamp.
The accompanying drawing explanation
Fig. 1 is that one of LED Ceiling light that a kind of radiating efficiency of the utility model is high is executed routine stereochemical structure decomposing schematic representation.
The realization of the utility model purpose, functional characteristics and advantage, in connection with embodiment, are described further with reference to accompanying drawing.
The specific embodiment
Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
