The photoluminescence fluorescent powder is evenly distributed in the mixed filling and sealing colloid which is formed by filling, sealing and curing.
Description
Technical field
The utility model relates to a kind of light emitting diode, and especially relating to a kind of half-power angle is the light emitting diode of 360 degree.
Background technology
The diode illuminating device of prior art, the general semiconductor light emitting chip that adopts the wide visual angle structure of band reflector, or column type surface single in the light-emitting device is made as frosted (wrinkle) structure, realize uniformly light-emitting by this, as CN 2590182Y patent case, the column type surface of its light-emitting device is provided with the frosted structure, US 6066861 patent disclosure cases " wavelength conversion filler and the application thereof " that disclosed for another example, be on the basis of traditional light emitting diode, assemble by sheathed reflector, make light to a direction radiation.Obviously, being similar to above-mentioned prior art, all can't to reach half-power angle be the luminous purposes of 360 degree.
Summary of the invention
For solving above-mentioned deficiency of the prior art, the purpose of this utility model provides a kind of diode illuminating device, and it is the diode illuminating device of 360 degree that a kind of half-power angle especially is provided.
The purpose of the utility model is achieved through the following technical solutions: it is by with the LED support of reflector, the semiconductor light emitting chip, and lead mixes the embedding colloid and has formed basic structure.Its characteristics are: be not fixed with the semiconductor light emitting chip on the LED support with reflector, and both finish the circuit connection by lead; Described mixed embedding colloid is by photoluminescent phosphor, transparent resin adhesive, and the packing material of antisolvent precipitation constitutes according to a certain ratio; Described semiconductor light emitting chip and not with the LED support of reflector by conventional fabrication processes, with mixing embedding colloid embedding curing molding, form basic structure body of the present utility model.
Beneficial effect
After using the technical program, because of the utility model, mixed embedding colloid is by photoluminescent phosphor, and transparent resin adhesive, the packing material of antisolvent precipitation constitute according to a certain ratio and integral body is not with reflector, just can realize 360 degree uniformly light-emittings.
The purpose of this utility model, feature and advantage will be elaborated in conjunction with the accompanying drawings by embodiment.
Description of drawings
Fig. 1: the structure chart of present embodiment;
Among the figure: 1, not with the LED support of reflector; 2, semiconductor light emitting chip; 3, lead; 4, mix the embedding colloid.
The specific embodiment
With reference to Fig. 1, the utility model is not by with the LED support (1) of reflector, semiconductor light emitting chip (2), lead (3), mixing embedding colloid (4) constitutes, it is characterized in that: be not fixed with semiconductor light emitting chip (2) on the LED support (1) with reflector, and both finish the circuit connection by lead (3);
Described mixing embedding colloid (4) is by photoluminescent phosphor, transparent resin adhesive, and the packing material of antisolvent precipitation constitutes according to a certain ratio; Described semiconductor light emitting chip (2) and not with the LED support (2) of reflector with mixing embedding colloid (4) embedding curing molding.
The utility model structure realizes the mechanism of white light: excite the photoluminescent phosphor (for example selecting YA6 fluorescent material for use) that mixes in the embedding colloid (4) to send gold-tinted by semiconductor light emitting chip (2) (for example its emission wavelength 460nm), blue light and gold-tinted are complementary light, then produce white light after spacing color mixed.
This patent structure realizes 360 degree space luminescence mechanism: semiconductor light emitting chip (2) has the performance that body is luminous or analog is luminous, semiconductor light emitting chip (2) is fixed on the LED support (1) of not being with reflector, can makes the semiconductor light emitting chip (2) more can be so equably to spatial emission; Be distributed with photoluminescent phosphor equably in the optics cavity that mixing embedding colloid solidify to form, and photoluminescent phosphor is to exist with the crystal grain shape, after it is excited by semiconductor light emitting chip (2) short wavelength, every crystal grain forms new light emitting source again to space luminescence, and in the optics cavity that mixing embedding colloid solidify to form, the packing material that also is distributed with antisolvent precipitation (as is selected SiO for use
2The time), this SiO
2Inserts has the effect of scattered light, the light that sends of semiconductor light emitting chip (2) in addition, and the reflected refraction effect that in mixing the optics cavity that the casting glue body forms, produces in the transmission course of the light that sends after being stimulated of photoluminescent phosphor, launch uniform 360 and spend space luminescence so just can realize this patent structure.
The simple change of present embodiment, and the simple change on the utility model basic structure; For example: semiconductor light emitting chip (2) is constituted by many semiconductor light emitting chips (2) with identical wavelength; For another example, the mixing embedding colloid of being made up of the packing material of photoluminescent phosphor, transparent resin adhesive, antisolvent precipitation (4) solidifies the geometrical body variation that the back occurs, and these simple variations all belong to the scope of this patent protection.
Claims (3)
