Lighting device

The present invention relates to a lighting device that reduces the light attenuation of the light source module, and the lighting device has a full-circumference illumination range.

According to the light-emitting diode (LED), it has many advantages such as high luminous efficiency, low power consumption and long service life, so that the light-emitting diode is widely used in various lighting fixtures, and the old conventional fluorescent lamp It is gradually replaced by a light-emitting diode lamp.

However, the illuminating diode has a limited illumination area and a certain illumination direction. Therefore, the illumination range applied to the luminaire is not wide enough to have a full-circumferential radial illumination range like that of a conventional fluorescent lamp. For example, a white light emitting diode lamp on the market is characterized in that a yellow fluorescent powder is coated on a blue light emitting diode, and the light source energy emitted by the light emitting diode can excite the yellow fluorescent powder to emit a yellow fluorescent light. The blue light emitted by the light-emitting diode is mixed with the yellow fluorescent light to form white light. However, the conventional fluorescent powder is directly coated on the light-emitting diode and packaged together in the same wafer layer. Therefore, the fluorescent powder is attenuated by the thermal energy of the light emitting diode, which causes the whole light emitting diode lamp to be unstable when the light is emitted, and the light decay occurs, and the luminous efficiency of the overall light emitting diode lamp (lm) /W) is not high, and the color temperature shift is also large.

In order to solve the above problems, the present invention provides an illumination device in which a phosphor layer in a light source module is not packaged in the same layer as a light emitting diode, so that the light attenuation of the light source module can be reduced, and the overall illumination can be improved. Efficiency, and the overall light source module can constitute a full range of illumination.

Wherein, the light emitting diodes are blue light emitting diodes, and the two light transmitting plates are composed of a transparent glass sheet and a phosphor layer containing phosphor powder, and the wafer layer is located in two transparent layers. Between the glass sheets, each of the phosphor layers is applied to each of the transparent glass sheets away from one side of the wafer layer.

According to the above, one of the functions of the present invention can be achieved. The phosphor layers in the light source module are not packaged in the same layer as the light-emitting diodes, so that the phosphor powder of the phosphor layer is not easily exposed to light. The polar body emits light and is attenuated by the influence of thermal energy. Therefore, the illumination device of the light source module is used in the present invention, and the light attenuation degree of the light source module can be reduced, thereby increasing the luminous efficiency of the overall light source module, and the color temperature deviation degree. Also small.

According to the above, the creation can achieve the second effect. The lighting device of the light source module is used in the creation, and the wafer layers of the two adjacent light source modules are at an angle of 120 degrees, so that the light source modules can be constructed.
