Description

A kind of LED lamp
Technical field
The utility model relates to a kind of lighting apparatus, is specifically related to a kind of LED lamp.
Background technology
Existing LED has been widely used on the various bulbs, what generally adopt only is the form that makes LED on original filament position into, the lamp socket that remains original structure that uses, because the illumination of LED has certain directionality, the illumination direction of LED is generally avoids lamp holder to the covering of light and select direction away from lamp holder, just lamp holder is last, and LED throws light on downwards or lamp holder is descending the structure of LED up ligthing.Particularly the position that often needs to design lamp holder in the illumination of public way is at the illuminating road that comes up, the lamp socket designs complexity.Use cost is higher and difficulty is installed, and the street lamp of installing on some enclosure walls, if the position that is designed to lamp holder is last, the structure that illumination direction is downward is destroyed easily and influenced environmental landscape; The lamp holder position is following, and the structure that illumination direction makes progress often causes a large amount of wastes of light source.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of illumination direction that is suitable for to the LED of lamp holder position lamp.
According to the LED lamp that the utility model proposes, comprise the lamp holder that can insert power supply, be connected lamp holder holder, transparent shell, radiator, the pcb board that LED is installed, LED driving power on the lamp holder, an end that it is characterized in that described transparent shell is connected with the lamp holder holder, the opposite end that transparent shell is connected with lamp holder is connected with the LED installed surface of pcb board, the pcb board another side connects radiator, lamp holder is electrically connected with the LED driving power, and the LED driving power is electrically connected with the LED of pcb board.
The LED installed surface of described pcb board is outwards outstanding circular arc or taper surface.The direction of the irradiation light of LED is disperseed more like this, and illuminating effect is better.
The one side that the LED installed surface of described pcb board is relative is fixedlyed connected with radiator, and the radiator that is fixed with pcb board is set to the screw thread limit with transparent shell or draw-in groove is fixedlyed connected.Radiator plays the effect that heat that LED is sent distributes, and radiator is fixedlyed connected with the mode that transparent shell is set to screw thread limit or draw-in groove, and promptly firm installing/dismounting easily again is very convenient to use.
Described transparent shell inner chamber lamp holder holder axis is provided with the surface and is the reflector of reflector layer.The light that gets off from the LED direct projection just can outwards reflect like this, avoids being stopped by the lamp holder holder, improves illuminating effect.
It is inclined-plane or oblique arcwall face that the surface of described reflector is set to respect to lamp holder holder axis.Can outwards reflect equably by light like this.
The surface of described reflector is a taper surface, and the bottom of reflector is in by lamp holder holder position.Taper surface improves illuminating effect as the more direction refraction earthward of light that reflecting surface can get off the LED direct projection like this.
Described LED driving power is placed on the radiator, and is electrically connected with lamp holder by the lead in the reflector.What the lamp holder holder can design like this is less, avoids obstructing the light; The LED driving power also can be placed on and be electrically connected with lamp holder in the lamp holder holder, and passes through the interior lead of reflector and be electrically connected with LED on the pcb board.
Fix with screw between described pcb board and the radiator, scribble heat sink material between pcb board and the radiator.Can coat siliceous or other heat-conducting mediums of heat radiation between pcb board and the radiator, improve the heat dispersion of LED, strengthen the stability of LED work.
The utility model designs LED at an end relative with lamp holder, the light emission direction of LED is towards lamp holder, when the utility model is applied to up position of lamp socket like this, the light emission direction of LED lamp of the present utility model down, be its illumination direction down, reach the illumination purpose, and solved wiring problem and the light problem that stop of LED design when the end relative, have good economic benefit with lamp holder.

The specific embodiment
Describe embodiment of the present utility model below in detail.
As Fig. 1, LED lamp of the present utility model comprises the lamp holder 1 that can insert power supply, is connected lamp holder holder 2, transparent shell 3, radiator 4, the pcb board 6 that LED light emitting diode 5 is installed, LED driving power on the lamp holder 1, one end of transparent shell 3 is connected with lamp holder holder 2, the opposite end that transparent shell 3 is connected with lamp holder 1 is connected with the LED installed surface of pcb board 6, pcb board 6 another sides connect radiator 4, lamp holder 1 is electrically connected with the LED driving power, and the LED driving power is electrically connected with the LED light emitting diode 5 of pcb board 6.The one side that the LED installed surface of pcb board 6 is relative is fixedlyed connected with radiator 3, and 4 bodies that dispel the heat are set to the screw thread limit with transparent shell 3 or draw-in groove is fixedlyed connected.
As Fig. 2, transparent shell 3 inner chambers of LED lamp of the present utility model are positioned at lamp holder holder 2 axis and are provided with the surperficial reflector 7 of reflector layer that is.The surface of reflector 7 is a taper surface, and the bottom of reflector 7 is in by lamp holder holder 2 positions.Taper surface improves illuminating effect as the more direction refraction earthward of light that reflecting surface can get off 5 direct projections of LED light emitting diode like this.The LED driving power is placed on the radiator 3, and is electrically connected with lamp holder 1 by the lead 8 in the reflector 7.What lamp holder holder 2 can design like this is less, avoids obstructing the light; The LED driving power also can be placed in the lamp holder holder 2 and be electrically connected with lamp holder 1, and passes through the interior lead 8 of reflector 7 and be electrically connected with LED light emitting diode 5 on the pcb board 6.
