Description

Have feed side and penetrate the LED bulb structure of light

Technical field

The present invention relates to lighting technical field, particularly about a kind of lamp holder upwards, the feed side of the reverse light projector type LED bulb of light irradiation downwards penetrates photo structure.

Background technology

With the international response environmental protection and energy saving policy of work, each advanced country has all set the time limit of withdrawing from the arena of osram lamp.The LED bulb is because replacement market energy-conservation, that brightness of illumination is included in osram lamp greatly.

The light source of traditional osram lamp is 360 ° a projection light, yet is the bulb of light source made with LED (SMD, wafer) at present, all can only do unidirectional projection light.When if the LED bulb of the unidirectional projection light of this kind will use on floor lamp, desk lamp, wall lamp or bedside lamp; Its projection light direction can only be toward the direction projecting beam of ceiling; For only throwing light on, has the problem of illumination deficiency significantly against the reverberation on the inclined-plane of the lampshade that is radiated at floor lamp, desk lamp, wall lamp or bedside lamp toward the projection light of floor direction.Therefore after osram lamp was withdrawn from the arena, this kind of light fixture all can only be replaced by the Electricity-saving lamp bulb of HCFL, CCFL type.

The Electricity-saving lamp bulb of right HCFL, CCFL type has ultraviolet ray, electromagnetism involves radiation etc., harmful human body, if nearly body uses, injury is hard iron more; And contain compositions such as mercury material and argon, neon, wherein mercury has more lethality for the injury of human body brain, kidney, skin and for the pollution in soil.Moreover the lamp body of HCFL, CCFL is glass material, and is very easily broken, but when fragmentation mercury metal dissipation of energy, if human body contact or suction can cause the pathology of brain and kidney.Face is the toxicity of decomposing H CFL, CCFL scrap, and the cost that is consumed is hard iron very, and is not inconsistent the environmental protection demand.In addition, HCFL, CCFL type bulb equally are that the light beam that is produced is discontinuous light with the discharge of electrode bump mercury gas as fluorescent lamp, and it can cause the vision of eyes tired, is unfavorable for reading.

For this reason, how the LED lamp envelope design is become can meet the for example range of exposures of using and increase projection light of light fixtures such as floor lamp, desk lamp, wall lamp or bedside lamp, real is LED dealer pressing matter, promotes environmental protection, energy-conservation necessary means especially.

Summary of the invention

Because above-mentioned problem, the object of the invention is promptly providing a kind of LED bulb structure that feed side is penetrated light that has.

The present invention realizes through following technical scheme: it comprises a transparent lamp socket, a transparent lamp case, a gripper shoe, an illuminating module, reaches a reflector.This transparent lamp socket comprises lower end and upper end; A lamp holder is installed in the lower end of this lamp socket; The upper end of this lamp socket forms an opening, and a driver is installed in the inside of this lamp socket. and this transparent lamp case is combined on this lamp socket and holds, and seals this opening and make this lamp socket and this lamp housing define a room jointly.This gripper shoe is supported in this room, and this gripper shoe comprises towards the upper surface of this lamp housing and towards the lower surface of this lamp holder.This illuminating module is located at the lower surface of this gripper shoe and is had several LED, and this illuminating module electrically is connected with this driver, makes this LED to be driven and towards the lower end throw light of this lamp socket.This reflector be located in this room and the position between this illuminating module and lamp holder, when this LED during throw light, can be produced the side projection light towards the lower end of this lamp socket by the reflector reflection.The LED of the present invention's LED lamp can form the projection light of downward direct projection and penetrate light by the limit that the reflective projection of reflector constitutes, and reaches the limit firing angle illumination that enlarges the LED lamp.

Preclude the use of the present invention, since the mirror will direct projection LED down light reflector produces side projection light, the light of the incident light angle greatly improved, making the LED lamps with traditional incandescent light bulbs light range, but also makes the application of LED lights range can be improved.
