Abstract
The utility model discloses a light-emitting diode (LED) fluorescent lamp comprising a heat dissipation base, a power supply, a circuit board and LED chips. The LED fluorescent lamp is characterized by further comprising a fluorescent shell, wherein the power supply is arranged in the heat dissipation base, the fluorescent shell is arranged on the top of the heat dissipation base, the circuit board is disposed on the heat dissipation base, the circuit board is provided with three LED chip arrays, each LED chip array is composed of 9 LED chips, the circuit board is connected with the power supply through a wire, and a plurality of heat dissipation holes are arranged in the fluorescent shell. The LED fluorescent lamp solves the problems that an LED lamp in the prior art is small in lamination range, has lamination blind areas, and is poor in use effect and heat dissipation effect, prone to being damaged, and short in service life. The LED fluorescent lamp has the advantages of being reasonable in structure, low in cost and wide in lamination range, and the circuit board can dissipate heat rapidly.
Description
Technical field
The utility model relates to a kind of LED lamp, particularly relates to a kind of LED fluorescent lamp.
Background technology
The single led chip setting of the at present many employings of LED lamp, the light that has caused like this LED lamp to send is spot light, range of exposures is less, exists the irradiation blind area, has brought larger inconvenience for user's use.
Only have in the course of the work simultaneously 15%～25% electric energy to convert luminous energy to, remaining electric energy nearly all changes into heat energy, the temperature of LED lamp is raise, and every increase by 10 its reliabilities of degree of temperature will reduce half.In high-powered LED lamp, heat radiation is a large problem, bad service life and the result of use that often has influence on whole LED of dispelling the heat especially.
The utility model content
Little in order to solve in the prior art LED light irradiation scope, there is the irradiation blind area, result of use is relatively poor, radiating effect is bad simultaneously, damages easily the problem that service life is short, it is a kind of rational in infrastructure that the utility model provides, with low cost, circuit board can quick heat radiating, the LED fluorescent lamp that range of exposures is wide.
In order to address the above problem, technical solution adopted in the utility model is:
A kind of LED fluorescent lamp, comprise cooling base, power supply, circuit board and led chip, it is characterized in that: also comprise the fluorescence cover, in cooling base, be provided with power supply, at the cooling base top fluorescence cover be installed, be provided with circuit board at cooling base, be provided with 3 led chip arrays at circuit board, each led chip array is comprised of 9 led chips, and described circuit board is connected with power supply by wire, offers some louvres at the fluorescence cover.
Aforesaid a kind of LED fluorescent lamp is characterized in that: be packaged with transparent silica gel at led chip.
Aforesaid a kind of LED fluorescent lamp, it is characterized in that: waterproof cover has been sealed up in the outside in transparent silica gel.
Aforesaid a kind of LED fluorescent lamp is characterized in that: described cooling base is the copper pedestal.
The beneficial effects of the utility model are: the utility model is provided with 3 led chip arrays at circuit board, each led chip array is comprised of 9 led chips, is undertaken luminously by the led chip array, and the light that sends is area source, range of exposures is large, and result of use is better.The utility model can conduct heat a large amount of on the circuit board fast by cooling base within the extremely short time simultaneously, and having avoided heat energy to be gathered in affects light quality and service life on the circuit board, and the service life of whole LED lamp is longer.
Description of drawings
Fig. 1 is the utility model LED fluorescent lamp structure schematic diagram.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 1, a kind of LED fluorescent lamp, comprise radiating copper pedestal 1, circuit board 2, led chip array 3, waterproof cover 5, fluorescence cover 6 and power supply, in radiating copper pedestal 1, be provided with power supply, at radiating copper pedestal 1 top fluorescence cover 6 is installed, be provided with circuit board 2 at radiating copper pedestal 1, be provided with 3 led chip arrays 3 at circuit board 2, each led chip array 3 is comprised of 9 led chips, be packaged with transparent silica gel 4 at led chip, sealed up waterproof cover 5 in the outside of transparent silica gel 4, prevented that led chip from meeting the water damage of making moist.
The utility model is provided with 3 led chip arrays 3 at circuit board 2, and each led chip array 3 is comprised of 9 led chips, is undertaken luminously by led chip array 3, and the light that sends is area source, and range of exposures is large, and result of use is better.The utility model can conduct heat a large amount of on the circuit board 2 fast by radiating copper pedestal 1 within the extremely short time simultaneously, and having avoided heat energy to be gathered in affects light quality and service life on the circuit board 2, and the service life of whole LED lamp is longer.
More than show and described basic principle of the present utility model, principal character and advantage.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
