Abstract

The utility model relates to an LED fluorescent lamp, which comprises a close cover, an LED light source, an LED aluminum substrate, a transmission cover and a heat radiator, wherein the LED light source is welded on the LED aluminum substrate; the transmission cover is fixed on the substrate and is covered above the LED light source; the heat radiator presents in a cylindrical shape, and heat radiation fins are uniformly distributed on the outer circumference of the cylinder, and one side of the cylinder is provided with a vacancy position, and the LED aluminum substrate is fixed inside the vacancy position; and both ends of the heat radiator cylinder are provided with the close cover, and the close cover fixes the transmission cover, the LED aluminum substrate and the heat radiator. The LED fluorescent lamp has the advantages of energy conservation, environmental protection, high brightness, small power consumption, long service life, impact resistance and the like. By adopting the large power LED light source, a favorable heat radiation is adopted to ensure the normal work of the LED, thereby having promising market prospect.

Description

A kind of LED fluorescent lamp
Technical field
The utility model relates to electronic technology and LED technical field, relates in particular to a kind of LED fluorescent lamp.
Background technology
Along with the quickening of Urbanization in China, green, efficient, energy-conservation, long-life LED illumination enters into people's the visual field gradually.The LED lighting engineering that is considered to the lighting source of 21 century reaches its maturity, because the LED luminescent device is a cold light source, the light efficiency height, operating voltage is low, and energy consumption is low, the led light source effect reaches more than the 801m/W, bears and the closely related various energy-saving lamps that match of people's productive life thereby drill.
Fluorescent lamp in the market generally adopts the low-power LED light source of Φ 5, Φ 8, and the little fault that can not cause of the heat that this fluorescent lamp short time illumination produces takes place.But in case lengthening, led light source just produces temperature rise when lighting hours, because existing LED lampshade structure is airtight, the heat of generation is difficult for distributing, and causes light decay bigger like this, and service life is short.
The utility model content
The utility model is at the above-mentioned defective of prior art, and a kind of have environmental protection, the life-span is long, photoelectric efficiency is high LED fluorescent lamp are provided.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
A kind of LED fluorescent lamp is characterized in that, comprising: capping, led light source, LED aluminium base, euphotic cover, radiator, described led light source are welded on the LED aluminium base; Described euphotic cover is fixed on the substrate, covers the led light source top; Described radiator is for being cylindric, and the equally distributed radiating fin of cylinder periphery is provided with a vacancy position in cylinder one side, and the LED aluminium base is fixed in this vacancy position; Radiator cylinder two ends are provided with capping, and euphotic cover, LED aluminium base, radiator are fixed in this capping.
Preferably, described euphotic cover is made with PC or PMMA transparent material.
As can be seen from the above technical solutions, the heat that the utility model distributes led light source is delivered to rapidly on the substrate, and radiating fin again leads from substrate, take away heat by flow air, guarantee the operate as normal of led light source, prolong the service life of led light source, have vast market prospect.
Description of drawings
Accompanying drawing is the utility model structural representation.
The specific embodiment
Below in conjunction with the specific embodiment the utility model is described in further detail.
Shown in accompanying drawing, the utility model comprises capping 1, LED aluminium base 2, euphotic cover 3, high-power LED light source 4, radiator 5, high-power LED light source 4 is welded on the LED aluminium base 2, on aluminium base 2, cover euphotic cover 3 again, radiator 5 is for being cylindric, the equally distributed radiating fin of cylinder periphery is provided with a vacancy position in cylinder one side, and LED aluminium base 2 is fixed in this vacancy position; Radiator cylinder two ends are provided with capping 1, and euphotic cover 3, LED aluminium base 2, radiator 5 are fixed in this capping, play the effect of dust seal.
As preferred implementation of the present utility model, described euphotic cover is made with PC or PMMA transparent material.
The above embodiment has only expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
