Abstract
The utility model relates to a LED daylight lamp. The LED daylight lamp comprises a metal base plate, one or a plurality of LED circuits arranged on one side surface of the metal base plate, controllers arranged at both ends of the metal base plate and a lamp cap respectively connected with a power supply, wherein, a radiation base plate is adhered on the back surface of the metal base plate, and the radiation base plate is detachably matched with a lamp shade to ensure the metal base plate to be covered in the lamp shade. Because the utility model adopts the technical proposal that the radiation base plate is adhered on the metal base plate, the heat produced during the luminescence process of a diode can be emitted in time, the influence of the heat to the diode is avoided well, and the service life of the daylight lamp is prolonged.
Description
Technical field
The utility model relates to a kind of lighting device, particularly a kind of LED fluorescent lamp that adopts led lighting.
Background technology
Respectively there is a filament at existing common fluorescent lamp two ends, are filled with the argon of trace and thin mercury vapour in the fluorescent tube, scribble fluorescent material on the tube inner wall, send ultraviolet ray during gaseous conduction between two filaments, make fluorescent material send soft visible light.Yet because mercury is poisonous, when fluorescent tube was broken, these mercuryvapours can be overflowed and human body is damaged.And this fluorescent lamp need be installed by starter or electric ballast just can be turned on light, and structure is comparatively complicated.
Along with deepening continuously of environmental protection and product safety idea, people have invented a kind of LED fluorescent lamp that adopts led lighting.This fluorescent lamp comprise the strip metal substrate that is provided with a plurality of LED and interlock circuit, gauge tap controller, be installed in lamp holder that the metal substrate both sides are connected with power supply and the cylindric glass lamp that is set in this metal substrate outside.Diode can constantly produce heat in luminescence process, the heat dispersion of this existing LED fluorescent lamp is relatively poor, and heat can not in time shed.Because the influence of the life-span of diode and performance received heat is bigger, thereby poor heat radiation can influence the service life of LED fluorescent lamp greatly.
Therefore, be necessary to design a kind of improved LED fluorescent lamp, to overcome above-mentioned defective.
The utility model content
The purpose of this utility model is to provide a kind of perfect heat-dissipating, the LED fluorescent lamp of long service life.
In order to reach aforementioned purpose, the related LED fluorescent lamp of the utility model comprises a metal substrate, is arranged on one or more led circuits, controller on this metal substrate lower surface and the lamp holder that is connected with power supply respectively, it is characterized in that: the upper surface of described metal substrate is pasted with heat-radiating substrate, and described heat-radiating substrate was located at metal substrate among the lampshade with removable cooperation of a lampshade.
The cross section of described heat-radiating substrate is roughly semicircular structure, and it comprises a horizontal surface, a curved upper surface and connect lower surface respectively and the joint face at upper surface two ends, and the cross section of described lampshade is an arcuate structure, and it has a upper end open.
Two ends of described upper surface are formed with slot with the joint face of this end respectively, and the wall portion of lampshade openend just can be inserted in this slot inside, forms removable cooperation.
The joint face of described heat-radiating substrate is being formed with groove respectively near the junction with lower surface, and the raised line that lampshade wall portion inboard is provided with corresponding to this groove, the wall part of lampshade openend are not inserted in the slot and the raised line of wall portion inboard is snapped onto in the groove.
Described lamp holder is installed in the two ends of lampshade and heat-radiating substrate.
The lower surface of described heat-radiating substrate and the centre position between the upper surface are equipped with gripper shoe.
Described heat-radiating substrate is made of aluminum.
Compared with prior art, advantage of the present utility model is: the utility model is owing to adopted heat-radiating substrate to be attached to technical scheme on the metal substrate, so the heat that diode produces in luminescence process can shed in time, thereby avoided the influence of heat well to diode, prolonged the service life of fluorescent lamp greatly
