Description

There is the LED lamp of integral type power supply

Technical field

This utility model relates to LED lamp field, particularly relates to one and has integral type power supply LED lamp.

Background technology

LED lamp, is used directly for illumination, it is also possible to be used as the substitution of the light source of conventional lamp, Diversified light array can also be integrated into for advertisement and decoration by handware.LED Operationally, the electric energy having about 80% is converted into luminous energy, and the electric energy of 20% is converted into heat Can, LED radiator is come to LED heat transmission, because LED chip is operationally, Inversely, temperature is the highest, and light emission rate is the lowest for he ambient temperature itself and light emission rate, When temperature reaches LED chip maximum operation (service) temperature, LED can break down.Temperature is to LED's In the life-span, light decay, color temperature shift has direct relation, so the design of LED lamp must have There is radiator structure.

And LED is the utility grid voltage that can not directly use routine.Due to LED The characteristic of light source, in order to meet special for LED voltage, current requirements, it is necessary to use especially The voltage conversion apparatus of design, just can make LED normally work.So LED lamp just has It is different from the power drives mode of conventional lamp, the power supply of i.e. extra coupling.

Generally radiator structure and the power supply of LED lamp separately designs, and therefore can take relatively Big installing space, too increases cost and the difficulty of installation and debugging, the most therefore causes LED Light fixture is just only used for special place, in order to meet the use of different places once having designed Demand, producer needs to develop number money and produces line, and user is also required to repeatedly purchase installation.

Preferably, described lens are screwed onto the lower surface of described base plate by screw.

Preferably, the height of described second fin is less than the height of the first fin.Now electricity Source module is fixed on the second fin, is not only beneficial to heat radiation, and can save space.

Preferably, it is positioned at the first heat sink of the base plate leftmost side and is positioned at the of the base plate rightmost side Being equipped with a L-type sidewall on one heat sink, each L-type sidewall all and forms one between base plate Link slot.Link slot can be used for accommodating connector, facilitates multiple LED with integral type power supply Connection between light fixture.

Preferably, connected by connector between multiple LED lamp with integral type power supply Becoming longitudinal array and/or horizontal array, described connector matches with L-type sidewall.

Preferably, described connector is that L-type connector, flat board connector and inverted T shape connect One in part.

The beneficial effects of the utility model are as follows:

This has the simple in construction of LED lamp of integrated power supply, takes up room little and is easy to Install.Wherein power module integrated installation is on a heat sink, can be directly accessed electrical network and use, Without additionally debugging and installation power supply, it is possible to be effectively saved space.It addition, this LED Tool can pass through connector forming array, its various shapes, can meet the demand of multiple occasion.

Detailed description of the invention

Below in conjunction with accompanying drawing and detailed description of the invention, this utility model is done and retouches further State:

Embodiment 1

Referring to Fig. 1 and Fig. 2, this utility model relates to a kind of LED with integral type power supply Light fixture, its better embodiment includes power module 1, radiator 2 and LED unit 3.

Concrete, sealing ring 31 that described LED unit 3 includes from top to bottom being sequentially placed, Pcb board 32 and lens 33, described pcb board 32 is socketed in sealing ring 31, described Lens 33 are removably attached to the lower surface of described radiator 2 so that sealing ring 31 and Pcb board 32 is fixed between radiator 2 and lens 33；Described power module 1 is fixed on scattered The upper surface of hot device 2, and power for pcb board 32.Wherein pcb board is provided with LED Source and the power supply circuits being connected with LED lamp source.Power module is electrically connected with city by wire, Thus power for LED unit, specifically it is pcb board and powers.Pcb board is close to radiator Lower surface, and dispelled the heat by radiator, it is possible to effectively reduce temperature.

It addition, radiator 2 includes base plate 21, some first fin arranged in parallel 22 and some second fin 23 arranged in parallel；Described first fin 22 is uniform Being arranged on the left and right sides of base plate 21, described second fin 23 is arranged in base plate 21 Between, and parallel with the first fin 22, described power module 1 is fixed on the second fin On 23.First fin and be arrangeding in parallel of the second fin can promote cross-ventilation, have Effect is dispelled the heat, and reduces heat and is gathered on pcb board, thus improves the use of LED unit Life-span.

Lens 33 are screwed onto the lower surface of described base plate 21 by screw.Second fin 23 Height less than the height of the first fin 22.Now power module is fixed on the second fin On 23, not only it is beneficial to heat radiation, and space can be saved.

As preferably, it is positioned at the first heat sink of base plate 21 leftmost side and is positioned at base plate 21 Being equipped with a L-type sidewall 24 on first heat sink of the rightmost side, each L-type sidewall 24 is equal And form a link slot 25 between base plate 21.Link slot can be used for accommodating connector, convenient many Connection between the individual LED lamp with integral type power supply.

Can be connected into by connector 4 between multiple LED lamp with integral type power supply Longitudinal array and/or horizontal array, described connector 4 matches with L-type sidewall 24.
