Light-emitting diode light source and lamp

The present invention relates to an illumination source and a lighting fixture, and more particularly to a light-emitting diode source and a lamp.

Please refer to FIG. 4A and FIG. 4B , which are respectively a schematic plan view and a perspective view of a conventional double-sided light-emitting diode (LED) light source. The light emitting diode light source includes a plurality of LED dies 61 and a substrate 62, and each of the LED dies 61 is disposed on the substrate 62. The substrate 62 is a rigid transparent substrate such as a glass substrate, a sapphire substrate (PSS) or a transparent ceramic substrate.

The two LED dipoles 61 are electrically connected through a connecting line 63. Specifically, each of the light-emitting diode crystal grains 61 has a connection point of two-phase different polarity, for example, a positive electrode connection point and a negative electrode connection point. The two ends of the connecting wire 63 are electrically connected to the negative connection point of the positive electrode connection point of the light emitting diode die 61 and the other light emitting diode die 61. Thereby, a plurality of light-emitting diode dies 61 disposed on the substrate 62 are connected in series through the connecting lines 63 to form the light-emitting diode source of the long vertical structure, and thus the light-emitting diode The body light source has a fragile nature.

Further, due to the structure of each of the connecting wires 63 itself, it is easy to disconnect the wires from the connection points of the corresponding light-emitting diode chips 61. Moreover, since the light emitting diode light source has to be connected to the light emitting diode crystal chips 61 via a plurality of the connecting wires 63, only the connecting wires 63 are directly connected to the connecting points without A more reliable way to connect will increase the chance of failure to break the wire.

However, since the light provided by the light emitting diode light source is limited by the light irradiation direction of the light emitting diode crystal grain, the light provided by the light emitting diode light source of the long vertical structure is projected only in the radial direction. Therefore, there is a dark region phenomenon in which the light-emitting dead angle exists in the axial direction of both ends of the light-emitting diode light source. In addition, the light-emitting diode light source cannot separately provide a 360-degree global uniform illumination range, and generally needs to arrange a plurality of light-emitting diode light sources in a ring shape, as shown in FIG.

However, a bulb using a plurality of long vertical light-emitting diode light sources still has a dark area where the light is dead at the top and bottom, and the entire illumination effect cannot be achieved. Furthermore, the use of a plurality of strip-shaped vertical light-emitting diode light sources requires the use of an additional metal conductor 52 as a support and electrical connection for the plurality of light-emitting diode strips 51, so that the process is relatively increased. The possibility of failure of the solder joint processing between the metal conductors 52 and the light-emitting diode strips 51 and the holder 53 is increased.

Since the substrate to be used is a hard and fragile glass substrate, a sapphire substrate or a transparent ceramic substrate, the length of the produced light-emitting diode light source cannot be designed too long, so that it is limited. The specifications and types of lamps that can be applied.

Referring to FIG. 5, it is a perspective view of a conventional double-sided LED lamp. The LED lamp 50 is a ball type bulb having a plurality of LED strips 51, and each of the LED strips 51 has the structure of the elongated LED source shown in FIG. 4A. Both ends of each of the light-emitting diode strips 51 are connected to the holder 53 via the metal conductors 52. Each of the metal conductors 52 is connected to the corresponding light-emitting diode strip 51 and the fixing frame 53 by soldering. In this way, the metal conductors 52 are not only provided for the corresponding connection between the LED strips 51 and the fixing frame 53, but also serve as the supporting LED strips 51 corresponding to the LEDs.

One of the aims of the present invention is to provide a light-emitting diode light source, which solves the dark region phenomenon in which the illumination provided by the long vertical light-emitting diode light strip has a light-emitting dead angle, and uses multiple light-emitting diodes for the purpose of improving the illumination range. The light source will increase the process and increase the likelihood of solder joint processing failure.

In order to achieve the foregoing disclosure, the light-emitting diode light source proposed by the present invention comprises a plurality of light-emitting diode crystal grains and a plurality of conductive carriers. Each of the conductive carriers is a sheet-shaped metal foil, wherein each of the light-emitting diode chips is commonly carried by two adjacent conductive carriers and electrically connected to the adjacent two conductive carriers to form A light-emitting diode light bar.

With the light-emitting diode light source, the length of the light-emitting diode light source can be lengthened according to requirements, and a multi-turn spiral structure can be formed to provide illumination directions in all directions to provide a uniform illumination range in the whole region. Furthermore, by the wide and flat conductive carrier structure, the connection with the light-emitting diode crystal grains can be strengthened, and each of the conductive carriers can be bent, so that the light-emitting diode light bar forms a curved spiral shape. structure.

Another object of the present invention is to provide a light-emitting diode lamp, which solves the problem that the light provided by the long vertical light-emitting diode light bar has a dark zone phenomenon of light-emitting dead angle, and in order to improve the illumination range, The use of multiple light-emitting diode sources in the luminaire will increase the process and increase the likelihood of solder joint processing failure.

In order to achieve the foregoing, the light-emitting diode lamp proposed by the present invention comprises a light-emitting diode light source, a lamp holder, an insulated lamp holder, a support member, a plurality of fixing members and a lamp cover. The lamp cap has a first connecting portion and a second connecting portion electrically connected to the conductive carriers at both ends of the LED strip. The insulating socket is fixed to the lamp cap. The support member has a horizontal portion and an upright portion, wherein the upright portion is disposed on the insulating socket, and the light emitting diode light source is spirally wound around the horizontal portion. Each of the fixing members fixes the light emitting diode light source on the horizontal portion of the support member. The lamp cover is disposed on the lamp cap and provides an accommodating space for accommodating the light emitting diode light source, the insulating lamp holder, the support member and the fixing members.

With the light-emitting diode lamp, the length of the light-emitting diode light source can be lengthened according to requirements, and more spiral structures can be formed, and in addition to providing illumination directions in all directions, the design can be further improved according to brighter requirements. Bright luminaires.

Moreover, the width of each of the conductive carriers 12 is a first width W1, and the width of each of the LED die 11 is a second width W2, wherein the first width W1 is greater than or equal to the second width W2. One half of the conductive member 12 has a sufficient connection width to reliably connect the corresponding positive electrode 112 and the negative electrode 113 to prevent the light-emitting diode die 11 from being disconnected from the conductive carrier 12.

Moreover, since each of the conductive carriers 12 has a metal foil structure, it is possible to provide heat dissipation to the heat generated by each of the light-emitting diode crystal grains 11.
