An LED lamp comprises a radiator, a lens, a ceramic substrate, LED illuminants, a driving power circuit and a wire, wherein the radiator is a round metal turned aluminum part and sequentially provided with a first segment of round counter bore and a second segment of round counter bore from top to bottom, the first segment of round counter bore and the second segment of round counter bore are coaxially arranged, the LED illuminants are annularly arranged, the driving power circuit is arranged in the center of the upper surface of the ceramic substrate, the LED illuminants surround the driving power circuit, and the driving power circuit is communicated with the LED illuminants. Due to the adoption of the structure and on the basis of the good electrical insulating property and the high heat conduction property of the ceramic substrate, the ceramic substrate and the radiator are attached and connected with a large area, heat radiation is full, and the service life of the LED lamp is prolonged; meanwhile, due to the design of the annular LED illuminants, generation of heat island effect is avoided, and light emitted by a light source formed by the annular LED illuminants is even and soft; a non-transparent mirror surface on the lens covers the driving power circuit, the driving power circuit can not be seen, and the LED lamp is more beautiful as a whole.

Description

A kind of LED lamp
Technical field
The utility model relates to lighting, especially a kind of LED lamp.
Background technology
At present, LED has energy-conserving and environment-protective, low-power consumption, and the advantage that optical efficiency is high becomes the modern principal light source throwing light on gradually.Existing LED modulated structure is the direct welding of aluminum substrate of mode that multiple LED chips are arranged with matrix, and aluminium base is fitted on metal heat sink, and by external drive means of power, the problem of existence has:
1, the LED illuminator being rearranged by multiple LED chips produces a large amount of heats while work, accumulates in heat on aluminium base and forms heat island effect, there will be serious light decay while causing LED to work long hours, affects the service life of LED lamp;
2, the circuit board of external drive supply unit uses pcb board, and its electronic component pastes small-sized radiator by the back of the body and dispels the heat, and radiating effect is poor, affects the life-span of driving power.
3, the power of driving power carries out unified configuration according to the general assembly quantity of LED module, and after power supply breaks down, whole LED lamp will quit work, and impact illumination is used.
Summary of the invention
The purpose of this utility model is: a kind of LED lamp is provided, and it is wide that it has illumination range, and lamplight brightness is even, long service life, and stable performance, packaging efficiency is high.
The utility model is achieved in that a kind of LED lamp, comprise radiator, lens, ceramic substrate, LED illuminator, driving power circuit and electric wire, described radiating element is circular metal car aluminum component, radiating element is from top to bottom provided with first segment circular counter bore and the second section circular counter bore of coaxial line successively, first segment circular counter bore and second section circular counter bore connect, the shape of first segment circular counter bore is identical with the shape of lens, and lens embed in first segment circular counter bore and coordinate; Described ceramic substrate is arranged in second section circular counter bore, ceramic substrate bottom and radiator laminating, its special character is: described LED illuminator distributes ringwise, described driving power circuit is arranged on the centre of ceramic substrate upper surface, LED illuminator is around driving power circuit, and driving power circuit is communicated with LED illuminator.
Position, described lens centre is set to nontransparent minute surface, nontransparent minute surface be positioned at driving power circuit directly over, the area of nontransparent minute surface is consistent with the circuit area of driving power.
A kind of LED lamp of the utility model, owing to adopting such structure, utilize ceramic substrate to there is the feature of good electric insulating properties and high-termal conductivity, annular LED illuminator and drive circuit setting are incorporated on the ceramic substrate of same a slice, ceramic substrate and radiator large area are fitted and connected, heat radiation fully, extends the service life of LED lamp; The design of annular LED illuminator, has avoided the generation of tropical island effect simultaneously, and annular LED illuminator forms light source and emits beam evenly soft; Nontransparent minute surface on lens hides on driving power circuit, and driving power circuit position is invisible, makes entirety more attractive in appearance.
Accompanying drawing explanation
Fig. 1 is the front view that the utility model provides a kind of LED lamp.
Fig. 2 is the cutaway view that the utility model provides a kind of LED lamp.
Fig. 3 is the exploded view that the utility model provides a kind of LED lamp.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of LED bulb, comprise radiating element 1, lens 2, ceramic substrate 3, LED illuminator 4, driving power circuit 5 and electric wire 6, described radiating element 1 is circular metal car aluminum component, radiating element 1 is from top to bottom provided with first segment circular counter bore 11 and the second section circular counter bore 12 of coaxial line successively, and first segment circular counter bore 11 connects with second section circular counter bore 12; The shape of first segment circular counter bore 11 is identical with the shape of lens 2, i.e. the equal diameters of the diameter of first segment circular counter bore 11 and lens 2, and the height of first segment circular counter bore 11 equates with the thick of lens 2, lens 2 are arranged on the interior cooperation of first segment circular counter bore 11;
Described ceramic substrate 3 is arranged in second section circular counter bore 12, ceramic substrate 3 bottoms completely and radiating element 1 be fitted and connected; Because ceramic substrate 3 has high thermal conduction characteristic, and substrate 3 is larger with radiating element 1 connection area, and the heat that LED illuminator 4 and driving power circuit 5 produce is distributed fully;
Described LED illuminator 4 distributes ringwise, and described driving power circuit 5 is arranged on the centre of ceramic substrate 3 upper surfaces, and LED illuminator 4 arranges around driving power circuit 5, and driving power circuit 5 is communicated with LED illuminator 4; Described LED illuminator 4 forms annular light source, and the tropical island effect that the structure of annular has avoided light source to produce effectively, reduces light decay;
The welding electronic elements of described driving power circuit 5 is on ceramic substrate 3, and the heat that driving power circuit 5 work produce, passes to rapidly radiator 1 through ceramic substrate 3, and radiator 1 is gone out dissipation of heat, effectively guarantees the stability of electronic component;
The centre of described lens 2 arranges a nontransparent minute surface 21, and the area of nontransparent minute surface is suitable with drive circuit area, and nontransparent minute surface hides directly over driving electronic component, and people watch less than driving circuit section, uses LED overall appearance generous.
Further illustrate, electric wire 6 connects civil power AC220V input, and on ceramic substrate 3, the driving power circuit 5 in centre is by rectifying and pressure-regulating, and out-put supply is given annular LED illuminator 4, the luminous work of LED illuminator 4; Utilize ceramic substrate to there is the feature of good electric insulating properties and high-termal conductivity, annular LED illuminator 4 and drive circuit 5 integration are arranged on the ceramic substrate 3 of same a slice, ceramic substrate 3 is fitted and connected with radiator 1 large area, and heat radiation fully, extends the service life of LED lamp.
Above-described is only preferential embodiment of the present utility model.It should be pointed out that for the person of ordinary skill of the art, in the situation that not departing from the utility model principle, can also make some improvement and modification, this is also considered as protection domain of the present utility model.
