Description

The LED tubular lamp

Technical field

The utility model relates to illuminating lamp, relates in particular to the LED illuminating lamp.

Background technology

Existing tubulose illuminating lamp, for example tubular fluorescent lamp is used widely owing to having wide in range field of illumination.But the service life of fluorescent tube is shorter, and economize on electricity, and its inside inadequately is filled with poisonous mercury, in case cracked, mercury can pollute indoor environment.Also bring into use the LED lamp to be used for illumination in the prior art, but existing LED lamp is generally circle, LED pipe wherein is installed on a small size zone, during illumination, belong to spot light, the field of illumination is not wide in range, as obtaining wide in range field of illumination, just need dot matrix that many LED lamps are installed, bring the big disadvantage of power consumption again.

The utility model content

Lack, be filled with harmful substance and the little shortcoming of existing LED lamp illumination zone at above-mentioned tubulose fluorescent lifetime, the applicant has carried out research and has improved, a kind of LED tubular lamp is provided, and it has wide in range field of illumination, has the advantage of long life and economize on electricity environmental protection again.

The technical solution of the utility model is as follows:

The LED tubular lamp comprises a strip radiating shell, at described radiating shell upper edge bar length direction the LED light-emitting device is installed, and installs lampshade below the LED light-emitting device, the two ends device end cap of radiating shell and lampshade on radiating shell.

Further, described LED light-emitting device comprises the insulated circuit plate, perforate on the insulated circuit plate, and the base of LED pipe is installed in the hole, and contact with described radiating shell, the lead-in wire of LED pipe interconnects by the copper foil circuit bar on the insulated circuit plate and is connected with power supply; Described LED light-emitting device comprises by conductive metal foil layer, insulating barrier, metal base plate presses the composite metal substrate that connects and composes layer by layer, led chip is linked on the conductive metal foil layer of composite metal substrate, the electrode of led chip interconnects by the circuit bar on the conductive metal foil layer and is connected with power supply, the metal bottom flaggy of composite metal substrate is installed on the described microscler radiating shell, is coated with protecting colloid on led chip; Described radiating shell is the heat-radiating substrate of a curved shape, and the outside of heat-radiating substrate is distributed with fin; Described heat-radiating substrate has the reflective surface of bending shape; The outside of described heat-radiating substrate is distributed with the radial fin of one with it.

In the utility model, the LED light-emitting device is installed, constitutes a LED elongate tubular lamp,, therefore have wide in range field of illumination just like existing tubular fluorescent lamp along the bar length direction of radiating shell; Its light-emitting device adopts LED pipe or led chip, has the advantage of long life, economize on electricity environmental protection.The utility model has the radiating shell of radial fin, make the LED plumber as the time have better heat radiating effect, further improve the power output and the working life of LED pipe.
