Abstract
A wide-angle LED bulb comprises a light-permeable lamp base and a light-permeable reflecting shell. A lamp cap is disposed at the lower end of the light-permeable lamp base. The inner end of the light-permeable reflecting shell is provided with a light-permeable reflecting film. A chamber is defined between the light-permeable reflecting shell and the light-permeable lamp base. A driver, a radiator and a light-emitting module electrically connected with the driver are disposed in the chamber. The light-emitting module comprises a substrate on the radiator and at least one LED disposed on the substrate. The light emitted from the LEDs can transmit through the light-permeable reflecting shell and a light-permeable housing to form upper projection light, and can be reflected by the reflecting film of the light-permeable reflecting shell to form lower reflected light; and the upper and lower projection lights project to the light-permeable lamp base and the light-permeable reflecting shell to form reflected halation which can form side projection halation, so that wide-angle light is formed.
Description
Technical field
The present invention is about a kind of bulb, particularly about a kind of LED bulb of wide projection angle.
Background technology
Along with the green energy of international response policy, each advanced country has all set the time limit of withdrawing from the arena of osram lamp.The LED bulb is also included the market that changes the outfit of osram lamp gradually in.
The illuminating module of traditional osram lamp is the projection light of 360o, however at present with LED(SMD, wafer) be the illuminating module made bulb 2,3,4(as shown in Figure 1 to Figure 3), all can only do unidirectional projection light.The LED bulb 2,3 of the unidirectional projection light of this kind, 4 design only can provide ceiling to use to the light fixture (DOWN LIGHT) of floor direction irradiation, if use at floor lamp 5(and see Figure 21) desk lamp 6(sees Figure 22), on wall lamp 7 or the bedside lamp (seeing Figure 23), its projection light direction can only be toward the direction projecting beam (seeing the Dl of Fig. 4) of ceiling, for only throwing light on 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 (seeing the D2 of Fig. 4) of floor direction, has the problem of illumination deficiency significantly.Therefore after osram lamp was withdrawn from the arena, this kind of light fixture 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., and harmful human body if nearly body uses, injures more huge; And it contains compositions such as mercury material and argon, neon, and 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.And be the toxicity of decomposing H CFL, CCFL scrap, the cost that is consumed is hard iron very, and is not inconsistent the environmental protection demand.In addition, HCFL, CCFL type bulb are that the light beam that produces is discontinuous light with the discharge of electrode bump mercury gas as fluorescent lamp, and the vision sleepiness that it can cause eyes is unfavorable for reading.
For this reason, how the LED bulb is established pin and become can meet 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 present invention's purpose is namely providing a kind of LED bulb of wide projection angle.This bulb comprises a printing opacity lamp socket, printing opacity reflection shell, a radiator, reaches an illuminating module.A lamp holder is installed in the lower end of this printing opacity lamp socket, and the upper end of this printing opacity lamp socket forms an opening.This printing opacity reflection shell is combined in to hold on this printing opacity lamp socket and seal this opening and makes this printing opacity lamp socket and this printing opacity reflection shell define a room jointly, the inner driver of installing of this room, this printing opacity reflection shell comprises an inner surface towards this lamp holder, and this inner surface is coated with a light transmission reflective membrane.This radiator is located in this room and comprises towards the upper surface of this printing opacity reflection shell and towards the lower surface of this lamp holder.This illuminating module has the substrate of being located at end face on this radiator and at least one and is located at LED on this substrate, and this illuminating module and this driver electrically are connected to make this LED to be driven and launch light.The light of LED emission can form projection light and reflect to form down reverberation via the reflective membrane that this printing opacity reflects shell via the transmission of this printing opacity reflection shell, and the upper and lower light of penetrating is incident upon this printing opacity reflection shell and can constitutes side projection halation with the formed reflection halation of this printing opacity lamp socket, and is luminous with the formation wide projection angle.
Accordingly, can make the projection light of the LED bulb of light fixtures such as being used in floor lamp, desk lamp, wall lamp or bedside lamp form full firing angle, form the required illuminating effect of the interior space and the needs that reach user's reading lighting.
In a preferred embodiment, this bulb more comprises a light transmitting shell, this light transmitting shell is combined in to hold on this printing opacity lamp socket and makes this printing opacity reflection shell position between this light transmitting shell and this illuminating module, and the light of LED emission can reflect to form down reverberation via the reflective membrane that this printing opacity reflection shell and this light transmitting shell transmission form projection light and reflect shell via saturating this printing opacity.Best, central construction one convex lens of this printing opacity reflection shell and/or this light transmitting shell is to improve the brightness of projection light on this.
