Abstract
The utility model belongs to the field of semiconductor illuminating, and discloses an improved LED fluorescent lamp comprising a bar-shaped aluminum substrate used for fixing LED lamp beads, a lamp cover, an aluminum alloy base and an aluminum alloy lamp shell. The aluminum alloy base and the aluminum lamp shell are integrated. The LED lamp beads fixed on the aluminum substrate are distributed in a shape like a Chinese character 'pin'. A rectangular groove is formed in the aluminum alloy base, the depth of the groove is a little larger than the thickness of the aluminum substrate, and a little smaller than the height of each LED lamp bead on the aluminum substrate. Therefore, the improved LED fluorescent lamp has the advantages of being high in luminous efficacy, uniform in brightness, good in heat dissipation effect, simple in structure and easy to produce.
Description
Technical field
The utility model patent of applying for belongs to field of semiconductor illumination.It is a kind of follow-on LED fluorescent lamp.
Background technology
LED is as a kind of light source, has energy-saving and environmental protection, life-span and the advantage such as grows, can keep in repair, so it has represented the developing direction of illuminating industry.Existing cast LED fluorescent lamp, normally the strip aluminium base with LED lamp pearl is fixed on the bottom of the aluminum alloy base that is provided with trapezoidal groove, like this, the contact area of aluminium base and aluminum alloy base is little to be unfavorable for heat radiation, make the too early generation light decay of LED fluorescent lamp, the lost of life.In addition, the lamp pearl of this LED fluorescent lamp is adopted facing each other being arranged in parallel at the strip aluminium base, and add upper lamp shade and produce easily later on hot spot, brightness irregularities, light efficiency is bad.
Summary of the invention
The purpose of this utility model overcomes the prior art deficiency exactly, provides a kind of light efficiency good, and good heat dissipation effect is the modified LED fluorescent lamp that is easy to produce simple in structure again.
A kind of modified LED fluorescent lamp, the aluminium base, lampshade, aluminum alloy base, the aluminium alloy lamp housing that comprise fixed L ED lamp pearl, be provided with rectangular recess at aluminum alloy base, aluminium base be fixed on bottom portion of groove, aluminum alloy base and aluminium alloy lamp housing with heat conductive silica gel be integrated.
LED lamp pearl is isosceles triangle at aluminium base arranges, and the degree of depth of rectangular channel is a little more than aluminium base thickness, a little less than the height of lamp pearl on the aluminium base.Can significantly improve light efficiency like this, overcome the defective of existing LED fluorescent lamp brightness irregularities.
Description of drawings:
Fig. 1 is a kind of modified LED fluorescent lamp profile.Fig. 2 is a kind of modified LED fluorescent lamp top view.
Description of reference numerals: 1 LED lamp pearl, 2 aluminium bases, 3 outer covers, 4 rectangular recess, 5 screws, 6 aluminum alloy casings
Son is inserted in the 8 LED fluorescent lamp shutoff 9 of 7 aluminum alloy bases
The specific embodiment: a kind of modified LED fluorescent lamp, the bead weld of LED lamp is connected on the aluminium base 2 through wiring of widening, LED lamp pearl adopts isosceles triangle to arrange.The shutoff 8 of LED fluorescent lamp and fluorescent tube are screwed by screw 5.Aluminum alloy casing 6 and aluminum alloy base 7 are integrated, and aluminum alloy base 7 is provided with rectangular recess 4, and the aluminium base 2 usefulness heat conductive silica gels of widening are fixed on the bottom of rectangular recess 4.Like this, because the contact area of aluminium base 2 and aluminum alloy base 7 strengthens, can significantly improve radiating effect, slow down light decay speed, prolong LED fluorescent lamp service life.Because again a little less than the height of LED lamp pearl 1 on aluminium base 2, and LED lamp pearl 1 adopts isosceles triangle to arrange a little more than the thickness of aluminium base 2 for the degree of depth of rectangular recess 4, like this, strong raising the light efficiency of led fluorescent lamp, and make its brightness even.The LED driving power directly is placed in the aluminum alloy casing, makes the heat Homogeneouslly-radiating of power supply.
Claims (2)
1. modified LED fluorescent lamp, the aluminium base, lampshade, aluminum alloy base, the aluminium alloy lamp housing that comprise fixed L ED lamp pearl, it is characterized in that being provided with rectangular recess at aluminum alloy base, aluminium base is fixed on bottom portion of groove, aluminum alloy base and aluminium alloy lamp housing with heat conductive silica gel is integrated.
2. a kind of modified LED fluorescent lamp according to claim 1 is characterized in that, LED lamp pearl is isosceles triangle at aluminium base arranges, and the degree of depth of rectangular channel is a little more than aluminium base thickness, a little less than the height of lamp pearl on the aluminium base.
