Description

Novel surface mounting type LED fluorescent lamp

Technical field

The utility model relates to lighting, specifically is a kind of novel surface mounting type LED fluorescent lamp.

Background technology

At present, in our daily life, no matter be electricity-saving lamp or common fluorescent lamp, its lighting angle all is a full angle, because the luminous zone maximization that could realize illumination of full angle.Because the LED electroluminescent lamp is subjected to the restriction of the principle of luminosity of self, therefore there is not good LED fluorescent lamp to come out at present.And present most LED electricity-saving lamp all is to be assemblied on the common line plate of common paper substrate or glass fabricbase, use plastic casing, promptly ventilate and also be difficult to resolve certainly heat dissipation problem, also exist simultaneously and be difficult to moistureproof dustproof problem, high and moisture problems is difficult to fully increase the service life because of heat to cause LED.

SMD is the abbreviation of Surface Mounted Devices, mean: surface mount device, it is a SMT (Surface Mount Technology Chinese: surface mounted technology) a kind of in the components and parts, the LED of SMD type refers to carry out surface-pasted light emitting diode, have the packing density height, little, in light weight by the electronic product volume of its production, the volume of patch light-emitting diode has only about 1/10 of traditional plug-in mounting light emitting diode, reliability height.And existing fluorescent lamp is equipped with four lead risers, and what still generally adopt is single-ended input, the circuit of single-ended output, and the mode of connection is restricted.

The utility model content

The technical problem that the utility model solved be to provide a kind of simple in structure, lamp hole temperature is low, long service life, surface attaching type LED fluorescent lamp that efficient is high.

The technical problem that the utility model solved realizes by the following technical solutions:

A kind of novel surface mounting type LED fluorescent lamp, comprise that two ends respectively are provided with the LED daylight light fixture of two lead risers, the Cap casing that is equipped in the light fixture two ends respectively, and be arranged on lampshade between the Cap casing, wherein power transformer also is installed in the LED light fixture, it is characterized in that: also comprise the circuit aluminium base, be installed in the paster LED on the circuit aluminium base, the two ends of circuit aluminium base are assembled together with the Cap casing at light fixture two ends respectively, join by the base plate of LED light fixture and the conductive electrode at two ends, in described LED light fixture, also be provided with the screw fixed hole position.

Each two lead riser that are provided with of described LED light fixture two ends can select to import power supply arbitrarily, can short circuits after powering up, guarantee that the normal mounting of light fixture is used.

The base plate of described LED light fixture adopts the aluminium base structure, is used to transmit power supply and heat radiation fully.

Described paster LED is that LED is arranged the back encapsulation in flakes, and the row that distribute at least on the circuit aluminium base play that lighting angle is big, light decay is little, the life-span is long and generate heat little effect.

Described LED lampshade carries out the light DIFFUSION TREATMENT on the surface, be used for can't see when the LED fluorescent lamp is lighted the LED lamp point in the lamp.

Described LED light fixture is made by aluminium alloy, and further technical scheme is that radiating groove is set on inwall, is used to strengthen the further heat radiation of light fixture, simultaneously built-in power transformer is played a protective role.

The beneficial effects of the utility model are that installation is simple, security performance is good, and can be arbitrarily select the input power supply at the two ends of fluorescent lamp, and so not only high efficiency, long-life, and environmental requirement is little, can be in temperature-25 ℃--80 ℃, steady operation in the humidity 10%--95%RH scope.The built-in design of the bottom aluminium alloy structure of LED light fixture and power converter simultaneously also allows and has greatly improved on the whole fluorescent lamp overall appearance.
