Description

The LED Ceiling light

Technical field

The invention belongs to the LED technical field, particularly a kind of LED Ceiling light.

Background technology

Existing LED Ceiling light generally all is that the alight bead weld is connected on the aluminium base, and then by lead connection driving chip, a lampshade is installed in the outside of lamp pearl simultaneously to be encapsulated in whole alight pearl and aluminium base and driving chip in the airtight housing all, so both prevented the environment of outside to the damage to the illuminator of the inside, the light that the lamp pearl is sent reaches better illuminating effect through lampshade.But the heat that such structure produces illuminator can not be dispelled the heat timely, and the time has been grown the service life that can influence the LED lamp.And the prior art overall fault is embodied in following three aspects: one, radiating effect is bad, two, lighting angle is bad, three, the driving power poor quality.

Summary of the invention

The purpose of this utility model is to provide a kind of good heat dissipation at the deficiencies in the prior art, illumination height, the LED Ceiling light that the driving power quality is high.

The utility model is by the following technical solutions to achieve these goals:

A kind of LED Ceiling light comprises aluminium base and LED lamp pearl, it is characterized in that: described LED lamp pearl is arranged in the multilayer round from outside to inside on aluminium base, the LED lamp pearl height of each circle from outside to inside increases progressively.

In the such scheme, also comprise radiator, described radiator is connected with aluminium base.

In the such scheme, also comprise the disjunctor lens that are fixed with aluminium base.Conventional lenses is formed to be made up of lens and panel mirror and is not disjunctor, the luminous energy scioptics that LED produces and irradiance and the brightness of panel mirror weaken, can not reach the best effect of irradiation, the disjunctor lens of this novel invention can effectively solve the aforesaid drawbacks, and the luminous energy that LED produces can both reach optimum efficiency by disjunctor lens lighting degree and brightness.

In the such scheme, described disjunctor lens adopt 60 degree transmissive mirror.Lens commonly used are 30 degree on the market, and its shortcoming is that the illuminance area of shooting downward is little, and the novel product LED of my company Ceiling light adopts 60 degree transmissive mirror, and the area of shooting downward is more wide, and light is softer, and effect is better.

In the such scheme, also comprise driving power, described driving power comprise electromagnetic interface filter, rectifier bridge, realization power factor emendation function by the streaming circuit unit, finish the inverse-excitation type switch power-supply circuit of isolating output and transformation function, realize the control chip U1 of the switch control functions of inverse-excitation type switch power-supply circuit, described electromagnetic interface filter connects rectifier bridge, rectifier bridge connects by the streaming circuit unit, connects inverse-excitation type switch power-supply circuit and control chip U1.

The utlity model has following beneficial effect:

Once, bad this problem of radiating effect, the radiator that the utility model adopts is to select for use the high light car of high-quality aluminium (4 millimeters) to dock with the seamless processing of aluminium base, and the heat of big illuminator generation is in time distributed.

Two, traditional LED Ceiling light lighting angle has only 30 degree, and the light irradiated area is little, and reality is that 60 degree transmissive mirror have effectively solved the little problem of irradiated area with novel employing, and illuminating effect is better.

What three, driving power in the past adopted all is the electronic devices and components of general plug-in type, low quality, power and stability are with originally not reaching requirement, the components and parts that the utility model adopts are combinations of half plug-in unit, half surface mount elements, be added with a self-excitation control IC, element is selected for use, all be the product through the tester test passes of specialty, yet whole driving power quality effectively is protected.

The specific embodiment

LED Ceiling light of the present utility model is by being arranged in the multilayer round from outside to inside with LED lamp pearl on aluminium base, the LED lamp pearl height of each circle from outside to inside increases progressively, such arrangement situation at first makes LED lamp pearl be third dimension, space interval between the lamp pearl is bigger than at grade, more be conducive to heat radiation, because lamp pearl originally all is to squeeze on same plane, the space is narrow and small to be unfavorable for heat radiation; Secondly lamp pearl to be that third dimension can make be that the light that sends is more even, illuminating effect is better, the quantum jump of this my company's innovative product.

This Ceiling light connecting relation, outlet fixture, radiator, aluminium base fixture, aluminium base, LED lamp pearl, disjunctor lens and lamp body fixture; Outlet fixture, radiator and aluminium base fixture are enclosed first cavity, power supply places outside the lamp body, line end is enclosed second cavity in the middle of the power supply, aluminium base and LED lamp pearl place in first cavity, aluminium base is fixedlyed connected with the aluminium base fixture, LED lamp pearl be fixed on the aluminium base and exiting surface towards the disjunctor lens; Disjunctor lens and aluminium base are fixed, and pearl is electrically connected with power supply the LED lamp.This LED Ceiling light adopts lamp to drive isolating construction, and power supply is positioned at second cavity, and LED lamp pearl is positioned at first cavity, disjunctor lens and aluminium base engagement connection, and that each parts connects is compact, integral heat sink is good, easy for installation and can not damage the lamp pearl when dismantling.

Among the figure: F1 is fuse, L1, and C11, L2, C12 forms common mode and differential mode electromagnetic interface filter.C2, C3, D3, D4, D6 constitute one by streaming circuit realization power factor emendation function.Through by behind the streaming circuit, by T1, Q1, D1, the inverse-excitation type switch power-supply circuit that C5 constitutes finish and isolate output and transformation function, and control chip U1 realizes the switch control functions of inverse-excitation type switch power-supply circuit.It is simple that inverse-excitation type switch power-supply circuit has a circuit structure, and safety is isolated, and is fit to the requirement of low-power LED driving power.And the inverse-excitation type switch power-supply circuit that adopts former limit switch control mode has saved secondary output constant current constant voltage testing circuit and optocoupler, has improved system reliability and cost performance.
