Abstract

The utility model discloses an LED fluorescent lamp used for illumination, which comprises an aluminum alloy casing, wherein a drive power supply circuit board is embedded in an inner chamber of the aluminum alloy casing; a curved-surface-shaped cambered surface is formed at the upper part of the aluminum alloy casing; strip-shaped aluminum baseplates are connected to the cambered surface of the aluminum alloy casing; LEDs are welded on the aluminum baseplates; a circular arc-shaped cover is embedded in the aluminum alloy casing; two ends of each of the circular arc-shaped cover and the aluminum alloy casing are connected with plastic or metal plugs; and the whole lamp body is fixed on a ceiling or a wall through a metal elastic clamp, and can be also fixed on two disconnected points with a suitable distance in the middle. A lamp tube and a bracket are integrated, the structure is simple and reasonable, and the lamp is convenient to mount; the cover and the aluminum alloy casing are connected into a whole, the work is easy and fine, the appearance is made to be attractive easily, and the whole lamp can be made to be elegant and high-grade easily; and further, the light emitting direction of each row of the LEDs is designed to be perpendicular to the cover surface, so that the refraction loss is reduced.

Description

The LED fluorescent lamp

Technical field

The utility model relates to a kind of fluorescent lamp for illumination, especially relates to a kind of LED fluorescent lamp.

Background technology

Known LED fluorescent lamp mainly is comprised of fluorescent tube, support two large divisions, the structural design of such LED fluorescent structure imitation traditional fluorescent lamp, have following shortcoming: 1. fluorescent tube, support two parts are separated, therefore complex structure; 2. driving power or be arranged on causes the driving power installing space serious limited and be unfavorable for heat radiation in fluorescent tube, otherwise separate with fluorescent tube be arranged on cause in support install loaded down with trivial details; 3. between fluorescent tube and driving power, perhaps between driving power and supply line, adopt " U " type connector to connect, not only dangerous but also easily damage; 4. the material of support uses plastics or iron sheet to be shaped usually, often moulding coarse, do not improve grade; 5. LED generally is distributed on the planar shaped aluminium base according to 2,3 rows, and like this, the LED light-emitting area is the plane, yet lampshade is arc surface, this has just caused the LED that only has at most 1 row in the cover, and its radiation direction is vertical with cover, and the light of the LED of other more rows has all increased refraction loss.

Summary of the invention

For overcome known LED fluorescent structure complicated, be unfavorable for dispelling the heat, defective that the light refraction loss is large, the utility model provides a kind of LED fluorescent lamp, this LED fluorescent structure is simple, be beneficial to heat radiation, the light refraction loss is little.

The technical solution of the utility model is: this LED fluorescent lamp comprises aluminum alloy casing, the aluminum alloy casing inner chamber embeds driving power circuit plate, be provided with the planar cambered surface of folding above aluminum alloy casing, be connected with the aluminium base of strip on the cambered surface of aluminum alloy casing, be welded with light emitting diode above aluminium base, the circular arc cover is embedded in above aluminum alloy casing.The two ends of circular arc cover and aluminum alloy casing all are connected with plastics or metal plug.Whole lamp body fastens on ceiling or wall by metallic elastic, on the point of two suitable distance that are not connected in the middle of also can being fixed on.

The cross section of aluminum alloy casing is rectangle, the equal diameters of rectangular wide and circular arc cover, and rectangular height can be decided according to the size of driving power circuit plate.Cambered surface above aluminum alloy casing is concentric with the arc surface of circular arc cover, has enough thickness to satisfy the needs of LED heat radiation.

LED is uniform to be welded on the aluminium base of every, and aluminium base is screwed on the folding face on the aluminum alloy casing cambered surface and makes it to fit tightly with heat conductive silica gel blind.The circular arc cover is embedded on aluminum alloy casing, with sealed light emitting diode.

The two ends of circular arc cover and aluminum alloy casing all seal with Plastic cap, and the plug at two ends all leaves aperture, are used for passing through of wire.

With the aluminium alloy shell part of known LED fluorescent tube, be improved to by traditional semicircular cross section and be approximate rectangular cross section, aluminium alloy shell part unites two into one with support and is called aluminum alloy casing.The face that two expressions of aluminum alloy casing are high and the wide face of expression are the plane, the face that another expression of aluminum alloy casing is wide, be improved to arc surface by traditional plane, and this arc surface is concentric with the arc surface of cover, the radius of this arc surface is less than the radius of the arc surface of cover, and concrete size is decided according to height and the luminous intensity distribution needs of light emitting diode L.

Installation method: two metallic elastic clamps are fixed on installed surface (ceiling or wall can be also to be in same plane but two points not being connected) according to the length of lamp, the two ends of lamp are withstood on metal clamps.

Advantage of the present utility model: 1. fluorescent tube, support two parts unite two into one, and are simple and reasonable, and it is also convenient to install; 2. driving power just is contained in aluminum alloy casing, and the inner cavity size of aluminum alloy casing is according to the size design of driving power, therefore, no longer exists the driving power size serious limited and be unfavorable for the problem of dispelling the heat; 3. between fluorescent tube and driving power in the inner chamber of aluminum alloy casing safety is connected, can adopt the direct of wire to be connected between driving power and supply line, avoided use " U " type connector to connect and the potential safety hazard and the rapid wear that cause are possible; 4. the cover, aluminum alloy casing is connected and do manual work easily do meticulously, outward appearance is easily done attractive in appearancely, whole lamp is easily done not only generously but also high-grade; 5. respectively arrange direction that LED emits beam and all be designed to vertically with cover, reduced refraction loss.
