Background technology

The LED luminescent device is widely used in various fields such as various light sources, screen, illumination.The LED luminescent device is compared to the traditional lighting utensil; Has significant advantage; For example lower power requirement, driveability, response speed, higher shock resistance, the service life of growing and environmental protection or the like faster preferably; Therefore, market increases the demand of LED luminescent device gradually, will substitute the traditional lighting utensil.

At present; Common LED luminescent device mainly contains following two kinds of forms: a kind of is the ball alveolitoid similar with conventional light source or the replaceable led light source of lamp tube type; The advantage of this LED luminescent device is that former light fixture can continue use; And the light source of replacing different colour temperatures is feasible, but its shortcoming is that heat radiation is bad, and the restriction of heat radiation significantly reduces brightness, life-span and the cost performance of led light source; Another kind is that integration light fixture and LED are one, and this design can realize efficiently radiates heat, the advantage of performance LED durable energy saving, but shortcoming is after the light fixture making finishes, and can't change the white light colour temperature of LED.

Along with being widely used of LED luminescent device, people also have a different requirement to the colour temperature of LED.Different use fields, desired colour temperature are also different.Early stage LED luminescent device changes colour temperature and realizes through changing LED module control circuit, and this method makes the complex circuit designs of LED luminescent device, realizes that cost high being difficult for realize.

In order to address this problem; Present technology is on LED blue light InGaN chip, to apply YAG (yttrium aluminum garnet; Yttrium-aluminium-garnet) the blue-light excited fluorescent material that fluorescent material, chip send produces the green-yellow light of 500-560nm, produces white light with blue light again.This mode preparation method is simple, is convenient to realize and the efficient height that cost drops into little, and circuit design is simple, has certain practicality.But light-emitting uniformity is poor, and the tone uniformity is bad, colour temperature be prone to depart from and colour rendering not ideal enough, and can not be quick to same device, the economic different colour temperature demand of realization.

The utility model content

The purpose of the utility model provides a kind of mechanism arrangement that the LED module sends the white light of different-colour that is used to regulate; This mechanism arrangement can overcome the weak point of prior art; Make the white light that produces have light-emitting uniformity and tone uniformity preferably; This mechanism arrangement is simple in structure simultaneously, is easy to realize having high economic benefit.

The purpose of the utility model is achieved in that

A kind of being used to regulated the mechanism arrangement that the LED module sends the white light of different-colour, comprising: one group of fluorescence plated film thin slice, and each sheet fluorescence plated film thin slice can produce the white light of different-colour respectively; One retaining collar is arranged on the top of LED module, installs a slice fluorescence plated film thin slice in the said retaining collar, and it is mouthful corresponding that the middle cavities of said retaining collar and the light source of the LED module of its below send.

Said retaining collar comprises holder and thin slice fixture, and said holder is used for retaining collar is fixed on the LED module, and said thin slice fixture is used for fixing fluorescence plated film thin slice.

Said thin slice fixture can be geometrical clamp; Said thin slice fixture also can be a retainer ring, is threaded or is buckled on the said holder.

Further, said retaining collar is fixed on the LED module, is installed in the said LED module 5mm～15mm of fluorescence plated film thin slice distance in the retaining collar.

Further, said every group of fluorescence plated film thin slice is selected from one or more in the following several kinds of models: 2700K white light, 3000K white light, 3500K white light, 4000K white light, 5000K white light.Select the fluorescence plated film thin slice of different model to be installed in the retaining collar during use, then can produce the white light of corresponding colour temperature.

Further, said mechanism arrangement also comprises high reflectance reflection tunica albuginea, is arranged on the middle part cavity inner wall of said retaining collar.

The utility model is owing to adopted technique scheme; Compared with prior art have following beneficial effect: the mechanism arrangement that the utility model provided, can replace the fluorescence plated film thin slice on the LED module quickly and easily, thus the colour temperature of the white light that change LED module sends; And the white light that produces has light-emitting uniformity and tone uniformity preferably; Making only needs replacement fluorescence plated film thin slice can change the colour temperature of white light simply, easily, and no longer need replace a new LED module, and it is simple in structure, enforcement is convenient; Practice thrift production cost widely, thereby realized huge economic benefit.
