Abstract
The utility model relates to a square LED (light-emitting diode) ceiling lamp, which comprises a chassis and a lamp shade, and is characterized in that a plurality of rows of LED lamp bulbs are circularly arranged on the chassis, and each row of LED lamp bulbs is composed of a plurality of LED lamp bulbs connected into a row in series and is connected to a constant current source circuit; a plurality of rows of LED lamp bulbs are equally divided into a plurality of LED lamp banks, a plurality of rows of LED lamp bulbs in each LED lamp bank are respectively connected to an aluminum base plate for heat radiation in parallel in a patch form, heat radiating fins at the bottom of the LED lamp bulbs are connected with the aluminum base plate, and the aluminum base plate is arranged on the chassis; the LED lamp bulbs are low-power LED lamp bulbs. The square LED ceiling lamp has high light efficiency and good color rendering property, cannot cause harm to the eyes of people, is energy-saving and environmental friendly, has low cost and is particularly suitable for decorative lighting in hotels, houses and public places.
Description
Technical field
The utility model relates to a kind of square LED lamp affixed to the ceiling.
Background technology
Lamp affixed to the ceiling is installed in ceiling, because light fixture top is more flat, installs near the roof, and similarly be to be adsorbed on the roof, so be called lamp affixed to the ceiling.Lamp affixed to the ceiling is installed simple and easy, simple generous, gives the space clear and bright lucid and lively sensation, and is suitable for decorative lightings such as household, public place, is very much practical.General light source has the common white bulb, fluorescent lamp, high-intensity gas discharge lamp, halogen tungsten lamp etc.But the utilization rate of electrical of white bulb, fluorescent lamp is low, and illumination effect is relatively poor, and the costing an arm and a leg of high-intensity gas discharge lamp, halogen tungsten lamp.Along with development of science and technology, the price of LED reduces gradually, and the LED lamp begins popularization and application, and price also reduces gradually, and the light efficiency of LED lamp is good, electric energy loss is low, long service life, and relatively environmental protection is attractive in appearance.
Summary of the invention
In view of the deficiencies in the prior art, the purpose of this utility model is to provide a kind of energy-conserving and environment-protective and lower-cost square LED lamp affixed to the ceiling, this square LED lamp affixed to the ceiling light efficiency height, colour rendering good, can people's eyes not damaged, energy-conserving and environment-protective, cost is lower.
To achieve these goals, the technical solution of the utility model is: a kind of square LED lamp affixed to the ceiling, comprise chassis and lampshade, it is characterized in that: be equipped with multiple row LED lamp pearl on the described chassis, each is listed as LED lamp pearl and is connected into row by a plurality of LED lamp pearls, and each is listed as LED lamp pearl and all is parallel in the constant-current source circuit.
Further, described multiple row LED lamp pearl is divided into some groups of LED lamp groups, each organizes some row LED lamp pearls in the LED lamp group respectively with on the SMD aluminium base that is connected in parallel on a slice heat transmission, and the fin of described LED lamp pearl bottom is connected with aluminium base, and described aluminium base is arranged on the chassis.
Further, described LED lamp pearl is a low-power LED.
Compared with prior art, the utlity model has following advantage: this square LED lamp affixed to the ceiling simple in structure, easy to use, its with multiple row LED lamp pearl as light source, light efficiency height, colour rendering are good, can people's eyes not damaged, energy-conserving and environment-protective, cost is lower, is specially adapted to the decorative lighting of hotel, household and public place.
Description of drawings
Fig. 1 is the organigram of the utility model embodiment.
Fig. 2 is the circuit theory diagrams of the utility model embodiment.
Among the figure: the 2-lampshade 3-LED lamp pearl 4-constant-current source 5-aluminium base of 1-chassis.
The specific embodiment
With reference to figure 1, a kind of square LED lamp affixed to the ceiling comprises chassis 1 and lampshade 2, it is characterized in that: be equipped with multiple row LED lamp pearl 3 on the described chassis 1, each is listed as LED lamp pearl 3 and is connected into row by a plurality of LED lamp pearls 3, and each is listed as LED lamp pearl 3 and all is parallel in constant-current source 4 circuit.
In the present embodiment, be divided into two groups of LED lamp groups by six row LED lamp pearls 3, each organizes the row of three in LED lamp group LED lamp pearls 3 respectively with on the SMD aluminium base 5 that is connected in parallel on a slice heat transmission, each is listed as LED lamp pearl 3 and is in series by ten LED lamp pearls 3, the fin of above-mentioned LED lamp pearl 3 bottoms is connected with aluminium base 5, and above-mentioned aluminium base 5 is arranged on the chassis 1; Above-mentioned LED lamp pearl is a low-power LED, and with reference to figure 2, the power of above-mentioned LED lamp pearl 3 can be 0.02W; The power of this constant-current source 4 is 5 ~ 12W, and family's alternating current of 220V is rectified into direct current through constant-current source 4 voltage stabilizings, for LED lamp pearl 3 illuminatings.This square LED lamp affixed to the ceiling adopts multiple row LED lamp pearl 3 as light source, and not only light efficiency height, colour rendering are good, can people's eyes not damaged, and energy-conserving and environment-protective, cost is lower, and market prospects are good, are specially adapted to the decorative lighting of hotel, household and public place.
The above only is preferred embodiment of the present utility model, and all equalizations of being done according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
Claims (3)
