Abstract

The utility model discloses an LED (Light Emitting Diode) light source directly driven by 220V. A substrate used for bearing and radiating consists of insulated high-heat-conducting aluminum nitride ceramic; a luminous surface with the diameter of 20.5 mm is drilled in the middle position of the surface of the substrate; an LED chip and a basic electronic circuit which is connected and formed in a series-parallel connection way are arranged on the luminous surface; ceramic capacitors, a starting resistor, a power resistor, a bridge rectifier and an alternated current input bonding pad are designed and surfaced-mounted at the positions which are 2 mm away from the luminous surface; an integrated drive power source is formed by the ceramic capacitors, the starting resistor, the power resistor, the bridge rectifier, the alternated current input bonding pad and a drive IC (Integrated Circuit). The LED light source directly driven by 220V has the advantage that the manual surface-mount cost and the power source assembling cost are effectively reduced.

Description

A kind of LED light source that can directly be driven by 220V

Technical field

The utility model relates to LED lighting field, relates in particular to a kind of LED light source that can directly be driven by 220V.

Background technology

Technical development and demand along with solid-state illumination, LED illuminating product has been widely applied to hotel's illumination, product introduction, high-grade leisure place etc., although the advantage of LED illuminating product is outstanding, energy-saving effect is obvious, but in view of current LED illuminating product fancy price comparatively, be still difficult to be accepted by household application market.For investigation, point out that the high price of LED illuminating product is nothing but to come from driving power, heat radiation external member, assembly cost, if LED illumination will be accomplished to most of family can be accepted in popular market, must improve the cost performance of illuminating product, reduce production costs, and the quality of production is not allowed carelessness.On existing market, the packaging technology of conventional LED lighting is all used SMD patch-type luminescent device, then mount and re-use solder reflow process after pcb board and fix, such a technique can expend the larger cost that manually mounts, and packaging efficiency is not high, the manufacturing process of driving power is also like this.

Summary of the invention

The purpose of this utility model is in order to solve prior art problem, and a kind of LED light source that can directly be driven by 220V is provided, and it can effectively reduce and manually mounts cost and power supply assembly cost.

The utility model is achieved in that

A kind of LED light source that can directly be driven by 220V, the substrate of carrying and heat radiation is comprised of the aluminium nitride ceramics of the high heat conduction of insulating, in the centre position of substrate surface, bore and dig the light-emitting area that diameter is 20.5mm, LED chip and the basic electronic circuit that uses series-parallel system to connect to form are placed in light-emitting area; Position Design outside light-emitting area 2mm is also pasted with ceramic condenser, starting resistance, power resistor, bridge heap and exchanges input pad, forms integrated form driving power with drive IC.

The utility model effect is that design includes heat dispersion heat sink, illuminating source, the three-in-one integrated form light source of driving power, LED lamp terminal client only need to connect with the mains line and install housing assembly can be practical, for having saved a large amount of cost and power supply assembly costs of manually mounting in terminal illumination market; And the utility model uses is light, heat, the design of electric integral type, so hommization more in terminal applies design, appearance design is more attractive in appearance easy.

Accompanying drawing explanation

Fig. 2: be structure schematic diagram of the present utility model.

The specific embodiment

Below in conjunction with legend, the utility model is further described.

As shown in Figure 1 and Figure 2, a kind of LED light source that can directly be driven by 220V, the substrate (10) of carrying and heat radiation is comprised of the aluminium nitride ceramics of the high heat conduction of insulation, in the centre position on substrate (10) surface, bore and dig the light-emitting area that diameter is 20.5mm (11), LED chip (1) and the basic electronic circuit that uses series-parallel system to connect to form are placed in light-emitting area (11); Position Design outside light-emitting area (11) 2mm is also pasted with ceramic condenser (3A, 3B), starting resistance (4), power resistor (5), bridge heap (8) and exchanges input pad (9), forms integrated form driving power with drive IC (6).After circuit and electronic device mount and have welded, in the bottom of substrate (10), inlay the fixedly aviation aluminium heat sink section bar (13) of active cool type, if be applied on illuminating product, user only need to lock and tighten up a screw in substrate screw hole (12), and can use at pad (9) line of connecting with the mains.

Above are only preferred embodiment of the present utility model, certainly, can also have other embodiment with further exploration according to actual needs.But, should be clear and definite, the conversion based on the similar embodiment with same idea above-mentioned or that other is not explained out, within all should being encompassed in protection domain of the present utility model.

Claims

1. the LED light source that can directly be driven by 220V, it is characterized in that: the substrate of carrying and heat radiation is comprised of the aluminium nitride ceramics of the high heat conduction of insulating, in the centre position of substrate surface, bore and dig the light-emitting area that diameter is 20.5mm, LED chip and the basic electronic circuit that uses series-parallel system to connect to form are placed in light-emitting area; Position Design outside light-emitting area 2mm is also pasted with ceramic condenser, starting resistance, power resistor, bridge heap and exchanges input pad, forms integrated form driving power with drive IC.
