Abstract
The invention relates to a laser light emitting diode vehicle lamp. The main structure comprises a lamp holder, a shell, a lampshade, a light condensing housing, a circuit board A, a control circuit board B and a laser light emitting diode, wherein the laser light emitting diode in the structure is arranged on the circuit board A; the lamp holder is connected with the shell; the control circuit board B is placed in the shell; the circuit board A is placed at the bottom of the light condensing housing; the control circuit B is connected with the lamp holder and the circuit board A respectively; the shape of the light condensing housing is designed in the way that light emitted by the laser light emitting diode forms diffused light but not a beam of light no matter whether the light is irradiated directly or reflected through the light condensing housing; the lampshade is adhered to the shell; and the laser light emitting diode is controlled by the control circuit board B to emit light.
Description
Technical field
The present invention relates to auto parts machinery and electronic applications, refer to a kind of lasing fluorescence diode car light especially.
Background technology
Since environmental problem is subjected to that the world is increasing and payes attention to, especially at automotive field, also strict gradually to the requirement of the toxic emission that how to reduce automobile etc.For this reason, how to promote reducing toxic emission or more energy-conservation technical scheme continues to bring out at automotive field.But these technology are based on to aspects such as engine, light weight, fuel, and as the important spare part car light of automobile, and are less and be not subjected to due attention because it improves energy-conservation influence.Though certain technological improvement is also arranged, namely substitute tengsten lamp with the LED lamp, though this also plays certain energy-saving effect, this substitutes main consideration is life-span of LED lamp to be longer than tengsten lamp.But the LED lamp has a shortcoming to be, though from energy-conservation or life-span, all improve a lot, but its quantity of heat production is also very high, we can say the LED lamp aspect the utilizing of energy except luminous available power, remaining energy all produces with the form of heat, such result is that the LED car light must use radiator, and this has increased production technology and cost.And the result that this defective causes is, when too much or radiating effect was bad when the heat that produces, the circuit part of LED car light caused easily and catches fire, and motor vehicle that this defective brings is fatal harm.
Therefore provide a kind of optical efficiency height, the safe car light that quantity of heat production is low is those skilled in the art's main target.The inventor is by making great efforts to propose a kind of technical scheme, and this technology can overcome the defective that the existing tengsten lamp life-span is short or the heating of LED lamp is high, also can overcome the above-mentioned defective of car light when improving service life.
Summary of the invention
The purpose of this invention is to provide a kind of technology, it is short service life because of tengsten lamp that this technology can overcome existing automobile lamp, the high defective that needs radiator of LED car light heating.
For achieving the above object, the present invention adopts the lasing fluorescence diode is arranged in the car light, because the lasing fluorescence diode is compared with LED lamp pearl or tengsten lamp, caloric value is low, in car light, do not need radiator, simultaneously by the improvement to control circuit, make the lasing fluorescence diode luminous stable.Adopt the car light of lasing fluorescence diode, its shell is with existing tengsten lamp or the LED lamp housing is identical can exchange, and realizes promoting saving and the practicality of the car light energy.
The present invention realizes by the following technical solutions:
A kind of lasing fluorescence diode car light, primary structure includes lamp socket, housing, lampshade, snoot, circuit board A and control circuit board B and lasing fluorescence diode constitute; The lasing fluorescence diode is installed on the described circuit board A in this structure, and described lamp socket is connected with housing; Described control circuit board B is placed in the described housing; Described circuit board A is placed in described snoot bottom, and described control circuit B is connected with circuit board A with lamp socket respectively; No matter the shape of described snoot is designed to guarantee light that described lasing fluorescence diode is launched and is direct projection or all forms diffused ray rather than become Ray Of Light through the reflection of snoot; Described lampshade is bonding on housing; Described control circuit board B control lasing fluorescence diode is luminous; Described control circuit B includes integrated drive, also is included in the shunt capacitance that will there be enough capacity at laser diode anode Vcc place, and described shunt capacitance is 0.1pF-1.0pF.
The shape of aforesaid snoot design is direct projection or all forms Ray Of Light through the reflection of snoot no matter can be designed to light that described lasing fluorescence diode launches according to the requirement of car light; Described shunt capacitance is 0.5pF-1.0pF.
The present invention compared with prior art has remarkable advantages and beneficial effect:
1, to compare with the LED of prior art, the luminous efficiency of lasing fluorescence diode is higher, and the life-span is similar with LED light pearl.
2, to compare with prior art, the caloric value of lasing fluorescence diode obviously reduces, and can solve the heat problem of lasing fluorescence diode fully by the effect of the thermistor in the drive circuit.
3, compare with prior art, because caloric value is low, saved the use of radiator, reduced production cost.
