Description

The LED bulb lamp

Technical field

The utility model belongs to the LED ligthing paraphernalia, particularly a kind of LED bulb lamp.

Background technology

Existing LED bulb lamp, it comprises a lamp holder, is arranged on the lamp socket on the lamp holder, the lamp socket upper end connects radiator, led driver is arranged in the radiator, is connected in the printed circuit board (PCB) of radiator upper end, and some led light sources are mounted on the printed circuit board (PCB), the LED electrode links to each other with driver through lead-out wire, illuminating part is PC or glass cell-shell, and lighting angle is 120 °, and lighting angle is less, the illumination comfortableness is relatively poor, and lamp power is limited.

Summary of the invention

The technical problems to be solved in the utility model is: provide for the problem of above-mentioned existence that a kind of lighting angle is large, the good LED bulb lamp of illumination comfortableness.

The technical scheme that the utility model adopts is: the LED bulb lamp, comprise the lamp holder, lamp socket and the radiator that connect successively, wherein in the radiator driver is set, the circuit board that is connected with actuator electrical away from lamp socket one end setting at radiator simultaneously, mount one group of LED on this circuit board, it is characterized in that: described radiator is provided for reflecting the reflector of LED light away from lamp socket one end, the printing opacity cell-shell that fixed installation has the light scattering function on this reflector simultaneously.

Described reflector is formed by connecting by the some fin that are evenly arranged, and its monnolithic case is identical with printing opacity cell-shell profile.

Described reflector adopts Heat Conduction Material to make, and with the radiator close contact.

Described reflector surface applies the light reflecting material that is used for changing radiation direction and reduces light absorption.

Described reflector surface applies has radiation characteristic to increase the material of radiating effect.

Described printing opacity cell-shell adopts the printing opacity PC or the transparent glass that include diffusant to make.

The specification of described lamp holder is E27, E26 or E14.

The beneficial effects of the utility model are: 1, the utility model arranges reflector in the LED upper end, change the direction of part LED light by reflection, thereby strengthened whole lamp lighting angle, the printing opacity cell-shell contains diffusant simultaneously, have the light scattering ability, part LED light is because scattering changes the path, so that the lamp luminescence angle is greater than 300 °, thereby improved illuminating effect, improved the illumination comfortableness.2, reflector is selected highly heat-conductive material, and closely links to each other with the radiator that led light source is installed, and has increased whole lamp area of dissipation, has strengthened the light fixture heat-sinking capability, has reduced the LED junction temperature, has improved lamp power and whole light flux.3, reflector surface applies highly reflective material, when changing the LED radiation direction, reduces light absorption, has guaranteed the brightness of illumination.4, reflector surface can apply the material with high radiant rate characteristic, further increases radiating effect.

The specific embodiment

Embodiment 1: such as Fig. 1, shown in Figure 2, present embodiment comprises that its specification of lamp holder 1(is E27, E26 or E14), be arranged on the lamp socket 2 on this lamp holder, and the radiator 3 that is connected in this lamp socket upper end, radiator 3 hollows and place a led driver 4 that is used for to the light fixture power supply wherein, the printed circuit board (PCB) 5 that is electrically connected with driver 4 away from lamp socket 2 one end settings at radiator 3 simultaneously, mount one group of LED6 on this circuit board, this group LED top (is positioned on the LED light path, be away from lamp socket one end on the radiator) reflector 7 be connected with described radiator 3 is installed, be used for reflecting part LED light, to change its path, the printing opacity cell-shell 8 that has the light scattering ability by the draw-in groove fixed installation on the described reflector 7 simultaneously.

As to further the improving and replenishing of technique scheme, the utility model also comprises the additional technical feature that following each section addressed, and they can be selected on the described technical scheme of epimere according to concrete effect when implementing the utility model.

Described reflector 7 is formed by connecting by the some fin that are evenly arranged, and its monnolithic case is identical or close with traditional bulb lamp or electricity-saving lamp (printing opacity cell-shell) profile.

Described reflector 7 selects high thermal conductivity materials to make, and closely links to each other with radiator 3, thereby has increased whole lamp heat-sinking capability.

As shown in Figure 3, apply highly reflective material on reflector 7 surfaces, when changing part LED radiation direction, reduce light absorption, guarantee the brightness of illumination.

Reflector 7 surfaces can also apply the material with high radiant rate characteristic, further increase radiating effect.

Described printing opacity cell-shell 8 is the abbreviation of the high transmission rate PC(Merlon that includes diffusant) or glass material make, possesses the light scattering function, as shown in Figure 4, light is when printing opacity cell-shell 8, because the scattering of printing opacity cell-shell interior media, part light has changed radiation direction to many-side, and this LED bulb lamp is photochromic evenly, and lighting angle is greater than 300 °.

Embodiment 2: as shown in Figure 5, the present embodiment structure is substantially the same manner as Example 1, and its difference is: the shape of described printing opacity cell-shell 8 is substantially cylindrical, and reflector 7 monnolithic cases are identical with it or close.
