Description

A kind of LED bulb lamp
Technical field
The utility model relates to a kind of lighting device, particularly a kind of LED bulb lamp with big lighting angle.
Background technology
The semiconductor lighting industry is risen in the whole world; LED (light emitting diode) becomes the focus that attracts the attention of millions of people, and the development of LED technology is also maked rapid progress, particularly after 2008; Along with the lifting of LED luminous efficiency and the lasting reduction of cost, LED begins to get on a large scale illumination market.
The LED bulb is as lighting device, and energy-conservation more about 80% than conventional incandescent, the life-span is more than 20 times of conventional incandescent, and does not have infrared ray and ultraviolet ray in institute's luminous spectrum.Advocate today that the technical ability environmental consciousness progressively promotes in energy crisis and people, the LED bulb has received great welcome.
Existing LED bulb roughly has two kinds of ways basically.First kind exactly with the great power LED paster of several 1W to aluminium base or directly be attached on the heat sink and go; Second kind is adopted integrated optical source, and the integrated area source of LED of a number watt mode through heat-conducting cream or pressing directly is fixed on the lamp body radiator structure spare.First kind of bulb structure is simple, but cost is higher, and connects through series-parallel mode owing to many; If a damage is arranged, whole bulb will be impaired, in addition; Because led light source is to be made up of several great power LEDs, therefore, it seems from the outside; Be easy to see the electric light source of the inside,, so just caused great luminous flux loss if realize with regard to needing the very poor lampshade of transparency in order to shield spot light; Second kind of structure is also comparatively simple, and cost is lower, and reliability is better, therefore, has become the main flow structure of LED bulb in the market; But, more than two kinds of structures a very serious problem is all arranged, that is exactly that the lighting angle of bulb is too little; Since LED to be the luminous area source of single face and conventional incandescent or fluorescent lamp 360 degree luminous different be that the lighting angle of LED bulb has only 0~180 degree; This just means; The light that LED the sends general space of can only throwing light on, and the space at the LED bulb back side shade will occur owing to be difficult to light and arrive; In order to address this is that; Also have much human to propose solution, mention a kind of LED bulb with the leaded light post like number of patent application for certain utility model patent of " 201020598806.2 ", this structure can solve the problem of shade really; It is below the leaded light post that but the limitation of this structure is its light source; The power of light fixture will be restricted like this, only is applicable to following small-power ornament lamp of 2W or candle lamp, can't realize civilian or commercial desired high-power; It is that the utility model patent of " 201020615034.9 " is mentioned at a kind of omnibearing luminous LED bulb that number of patent application is also arranged; It is that fixing various paster low-power LEDs are realized the wide-angle illumination around an erecting bed; This to do the heat radiation of big one side be a very big problem, and reliability is not good;
The utility model content
The technical problem that the utility model will solve is to overcome the defective of prior art, proposes a kind of new LED bulb lamp, and this bulb has bigger lighting angle (more than 240 degree), and heat radiation is good, and reliability is good, and durability is better.
For this reason; The utility model is taked following technical scheme: a kind of LED bulb lamp; Comprise lamp holder, lamp socket, driving power, heat dissipating housing and Transparent lamp shade; It is characterized in that being provided with in the described heat dissipating housing annular LED integrated optical source, secondary reflecting device of the outer setting of described annular LED integrated optical source.
Described annular LED integrated optical source comprises substrate, and blue-light LED chip is set on the substrate, applies the mixture of yellow fluorescent powder and silica gel on the described led chip.
Described secondary reflecting device comprises the clear glass cylinder, and the top of said cylinder is provided with the taper refractive body, and the bottom of said taper refractive body is the taper silvered face, and the top of said taper refractive body is the clear glass disk.
Angle between described taper silvered face and the clear glass disk is 5~45 degree, and described height of column is 10mm~50mm.
Angle between described taper silvered face and the clear glass disk is 15 degree, and described height of column is 18mm.
Described annular LED integrated optical source is fixed on the heat dissipating housing, and the contact-making surface of annular LED integrated optical source and heat dissipating housing scribbles heat dissipating silicone grease.
Described heat dissipating housing is aluminium section bar or die casting aluminium structure, and the surface is fin shape.
The beneficial effect of the utility model is to realize the control to space different angles light through an annular integrated LED light source and a secondary optics reflector; With reach light in the space equally distributed characteristics; Realize that particularly the LED lamp body back side has light to arrive, and eliminates shade; And this annular LED integrated optical source has good heat dissipation, low, the easy-to-install characteristics of cost.
