Abstract
The utility model discloses a semiconductor light emitting device comprising a substrate, a bracket, semiconductor light emitting chips and fluorescence glue, wherein the substrate is provided with an insulating layer and a conductive layer arranged on the insulating layer, the bracket forms an inward-concave opening and cooperates with the substrate to form a light projection port of a bowl structure of the semiconductor light emitting device; the semiconductor light emitting chips are electrically connected to the conductive layer; and the fluorescence glue coats the semiconductor light emitting chips and fills in the bowl structure of the semiconductor light emitting device. Moreover, the bracket is obliquely arranged relative to the substrate, and the semiconductor light emitting chips are arranged on the obliquely-arranged bracket. The semiconductor light emitting device used for displaying in the utility model has the advantages of simple structure and small light source waste.
Description
Technical field
The utility model relates to semiconductor light-emitting apparatus, especially relates to a kind of semiconductor light-emitting apparatus for showing.
Background technology
Semiconductor light-emitting-diode (Light Emitting Diode, LED) as lighting source of new generation, have the advantages such as green energy conservation, longevity, fast response time, be used widely gradually in applications such as view, indication, backlight and special lightings, wherein, LED display display frame is bright in luster, and third dimension is strong, is widely used in the public places such as station, harbour, airport, market, hospital, hotel, bank.
As shown in Figure 1, the LED that tradition is applied to show comprises: substrate 1 is provided with insulating barrier and is arranged on conductive layer on the described insulating barrier on the substrate 1; Support 2, support form the indent opening and cooperate the light projector mouth of formation semiconductor light-emitting apparatus bowl cup structure with substrate 1; Semiconductor luminous chip 3, semiconductor luminous chip 3 are arranged on the substrate 1 and are electrically connected described conductive layer.Because semiconductor luminous chip 3 is arranged on the semiconductor light-emitting apparatus bowl cup structure base plane substrate, angle is fixed and the forward light intensity, when LED display is positioned at the high-altitude, the forward light that LED sends can not be received by the ground observation person, cause the huge waste of light source, reduced simultaneously the visible angle of display screen.Therefore, be necessary to propose a kind of improvement, be used for showing the defective of LED to overcome tradition.
The utility model content
Technical problem to be solved in the utility model provides a kind of simple in structure, the semiconductor light-emitting apparatus that is applied to show that the light source waste is little.
To achieve these goals, the utility model by the following technical solutions: a kind of semiconductor light-emitting apparatus comprises: substrate is provided with insulating barrier and is arranged on conductive layer on the described insulating barrier on the described substrate; Support, described support form the indent opening and cooperate the light projector mouth of formation semiconductor light-emitting apparatus bowl cup structure with described substrate; Semiconductor luminous chip, described semiconductor chip is electrically connected described conductive layer; Fluorescent glue, described fluorescent glue coat described semiconductor luminous chip and fill described semiconductor light-emitting apparatus bowl cup structure; And: the corresponding described substrate of described support is obliquely installed; Described semiconductor luminous chip places on the described support that is obliquely installed.
As a kind of preferred technical scheme: the described holder part and the described substrate angle of inclination that are provided with described semiconductor luminous chip are that 10 degree are to 35 degree.
The utility model is used for the semiconductor light-emitting apparatus of demonstration, according to showing height, changes the semiconductor luminous chip angle of inclination, and is simple in structure, effectively avoided the light source waste, improves audient's visual experience effect.

Fig. 2 is the utility model semiconductor light-emitting apparatus cutaway view.
Embodiment
Below in conjunction with accompanying drawing, describe the utility model semiconductor light-emitting apparatus in detail: see also Fig. 2, the utility model semiconductor light-emitting apparatus comprises: substrate 1 is provided with insulating barrier and is arranged on conductive layer on the described insulating barrier on the substrate 1; Support 2, support 2 form the indent opening and cooperate the light projector mouth of formation semiconductor light-emitting apparatus bowl cup structure with substrate 1; Semiconductor luminous chip 3, semiconductor chip 3 is electrically connected with aforesaid substrate 1 conductive layer, excited by extraneous electric current and emits beam; The fluorescent glue (not shown), described fluorescent glue coats semiconductor luminous chip 1 and fills described semiconductor light-emitting apparatus bowl cup structure, and fluorescent glue is mixed by colloid and fluorescent material by a certain percentage according to the lumination of light emitting diode requirement.Semiconductor light-emitting apparatus substrate 1 conductive layer is electrically connected with external circuit, thereby make semiconductor luminous chip 3 obtain operating current, semiconductor luminous chip 3 is excited by operating current, emits beam, and is absorbed and send the light of different colours by fluorescent material in the described fluorescent glue.
As shown in Figure 2, the utility model semiconductor light-emitting apparatus, support 2 is asymmetrical bowl cup structure with the bowl cup structure that substrate 1 consists of, and support 2 has certain angle of inclination with substrate 1, and semiconductor luminous chip 3 is arranged on the clinoplain of support 2.Semiconductor luminous chip 3 places on the tilt stand 2, and forward light and semiconductor light-emitting apparatus mounting plane that semiconductor luminous chip 3 is sent have certain angle, thereby the light major part of sending is accepted by the audient, effectively avoids the light source waste.
The utility model semiconductor light-emitting apparatus, be mainly used in the high-altitude display module, consider that audient's sight angle and technique realize, the angle of inclination of support 2 and substrate 1 is the most suitable between 10 degree are spent to 35: the light waste that angle too small, semiconductor light-emitting apparatus are sent is larger; Angle is excessive, and the light that technique realization difficulty and semiconductor chip 3 send easily by the emission of semiconductor light-emitting apparatus bowl cup structure, affects light effect.
The utility model semiconductor light-emitting apparatus, luminescence chip is arranged on the tilt stand, forward light and mounting plane that luminescence chip sends have certain angle, can guarantee that the light major part that semiconductor light-emitting apparatus sends accepted by the audient, simple in structure, effectively avoid the light waste, guaranteed the visible angle of display unit.
Be the utility model case study on implementation only below, be not limited to the utility model, as long as the equivalence that those of ordinary skills do according to the utility model institute disclosure is modified or changed, all should include in the protection range of putting down in writing in claims.
