Abstract

The utility model discloses a light-emitting diode (LED) lamp and belongs to the technical field of LED illumination. The LED lamp comprises a front cover, a back cover, a junction box and a handle, wherein the front cover and the back cover are tightly fixed together through screws to form a hollow cavity in which an LED luminous plate is arranged, the outer surface of the back cover extends to form a heat dissipation fin which is connected with the back cover to form a whole, the heat dissipation area of the heat dissipation fin is designed to be 10 mm*50mm-15mm*60mm, the junction box is connected to the back cover, the back cover is provided with the U-shaped handle extending out of the junction box, and an actuator and a power supply module are arranged in the junction box which is electrically connected with the LED luminous plate. The LED lamp is simple in structure, convenient to install and manufacture, tight in contact due to the integral design of the heat dissipation fin and the back cover, and good in heat dissipation effect. The design of the handle facilitates lifting, placing and installing.

Description

A kind of LED lamp

Technical field

The utility model relates to the LED lighting technical field, is specifically related to the LED lamp of a kind of long service life, perfect heat-dissipating.

Background technology

The Semiconductor light-emitting diode lamp tool is LED(Light Emitting Diode) light fixture is a kind of semiconductor solid luminescence device.It is to utilize the solid semiconductor chip as luminescent material, by carrier compound energy of emitting surplus occurs and cause photo emissions in semiconductor, 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.

Under the background that Present Global energy starved worry raises once again, energy savings is the major issue that we shall face future, at lighting field, the application of LED luminous product is attracting common people's sight, LED is as a kind of novel green light source product, it must be following development trend, 21st century will enter the new type light source epoch take LED as representative, LED be called as the 4th generation lighting source goods green light source, have energy-conservation, environmental protection, long service life, the characteristics such as volume is little can be widely used in various indications, show, decorate, backlight, the field such as general lighting and urban landscape.The operating temperature of LED generally should be less than 50 ℃, show according to related data, when the LED operating temperature reaches 55 ℃, its life-span will reduce half, and especially those power are larger, need the long-time light fixture of opening, so heat dissipation problem is a major issue, radiator of the prior art generally is mounted on the housing of LED lamp, still can have certain slit between the housing of he and LED lamp, thereby cause the bad radiating effect that causes of contact effect also bad.

The utility model content

Technical problem to be solved in the utility model is to provide a kind of long service life, the LED lamp of good heat dissipation effect.

Technical problem to be solved in the utility model realizes by the following technical solutions:

A kind of LED lamp comprises protecgulum, bonnet, terminal box and handle, and described protecgulum and bonnet form a cavity by screw fastening together, be provided with the LED luminous plaque in the cavity, described terminal box is connected on the bonnet, is provided with U-shaped handle on the bonnet, and handle extends to outside the terminal box.

Described rear exterior surface is extended with fin, and fin and bonnet are linked to be an integral body, and the area of dissipation of described fin is arranged between the 10mm*50mm-15mm*60mm.

Be provided with driver and power module in the described terminal box and be electrically connected with the LED luminous plaque.

The beneficial effects of the utility model are: the utility model is simple in structure, installation, easy to make, and fin and the design of bonnet integral type, contact is tight, good heat dissipation effect; Handling and installation are convenient in the design of handle.
