Description
Technical field
The utility model relates to a kind of light-emitting device, refers to a kind of light-emitting device of the mode of total reflection light source with the increase light extraction efficiency that pass through to destroy especially.
Background technology
The invention of electric light can be described as the life style that has changed the whole mankind up hill and dale, if our life does not have electric light, night or weather conditions not good the time after, the work of all will be stopped; If be subject to illumination, the utmost point has can make building construction mode or human life style all thoroughly change, and therefore the whole mankind will can't improve, the age that stays on and fall behind.
So, today employed on the market lighting apparatus, for example: fluorescent lamp, tengsten lamp even the more popular till now Electricity-saving lamp bulb of being accepted are widely used in the middle of the daily life all.Yet this type of electric light has fast, the high power consumption of optical attenuation mostly, be easy to generate high heat, the life-span is short, frangible or shortcoming such as difficult recovery.Moreover; the color rendering of traditional fluorescent lamp is relatively poor; so produce pale light and be out of favour; in addition because principle of luminosity is 120 times quick flowing in a second of fluorescent tube two utmost point electronics; when firm unlatching and electric current instability, cause flicker easily; this phenomenon is considered to cause the arch-criminal of domestic high rate of myopia usually; but this problem can solve by means of the fluorescent tube of repacking with " high-frequency electrical minor stabilizer "; its high-frequency electrical minor stabilizer not only can fall 20% to the power consumption of traditional fluorescent lamp again; when lighting a lamp because of high frequency moment again; the light wave of output is highly stable; therefore almost flicker free takes place; and when power supply voltage variation or fluorescent tube are in low temperature, be not easy to produce flicker, this helps the protection of eyesight.Yet the stabilizer of general Electricity-saving lamp bulb and power-saving lighting tube all is fixed, if eliminate the words of trade-in, must connect stabilizer abandons together, moreover no matter fluorescent tube how power saving again,, still inevitably environment is caused serious pollution after discarded because of it contains the coating of mercury.
In order to address the above problem, a kind of light-emitting diode lamp tube in response to and give birth to.See also shown in Figure 1A, knownly provide a kind of light-emitting diode lamp tube, it has a circuit substrate 1a and a plurality of series connection and is arranged at light emitting diode 2a on this circuit substrate 1a electrically, and therefore luminous by described these light emitting diodes 2a is to produce the illumination effect of similar fluorescent lamp.Yet, because described these light emitting diodes 2a each interval one preset distance is arranged setting, therefore the light source that known light-emitting diode lamp tube produced has uneven situation and takes place, for example: the light source in zone meeting more intense (as the corresponding position of dotted line) under each light emitting diode 2a, but the zone between per two light emitting diode 2a then can produce more weak light source.Therefore known light-emitting diode lamp tube can't provide uniform light source.Moreover, because described these light emitting diodes 2a can produce superpower projecting beam, and cause the user can't look at known light-emitting diode lamp tube straight, and then cause user's inconvenience in the use.
In order to solve the problem that " known light-emitting diode lamp tube can't provide uniform light source " reaches " user can't look at light-emitting diode lamp tube straight ", usually the designer can be provided with a transparent lamp shade (figure does not show) below described these light emitting diodes 2a, with mixed light that carries out light source and the intensity that reduces light source.Yet this kind practice can reduce greatly light emitting diode 2a originally the light source usefulness that can provide.
In addition, see also shown in Figure 1B and Fig. 1 C, knownly provide a kind of light-emitting diode (LED) module, it has the light emitting diode 4a that a lamp guide 3a and is arranged on the short side of this lamp guide.At first the light beam L that produced of this light emitting diode 4a invests this lamp guide 3a earlier, and light beam L produces downward light projector effect by the guiding of this lamp guide 3a more then.Yet shown in Fig. 1 C, light beam can't shine wider scope (illumination of wider range can't be provided) by downward light projector zone (shown in dotted line) A that guiding produced of this lamp guide 3a.
So the improving of the above-mentioned defective of inventor's thoughts concentratedly observed and study it, and cooperates the utilization of scientific principle, and propose a kind of reasonable in design and effectively improve the utility model of above-mentioned defective.
